Article: It is a logical extension of the compound engine (described above) to split the expansion into yet more stages to increase efficiency. The result is the multiple expansion engine. Such engines use either three or four expansion stages and are known as triple and quadruple expansion engines respectively. These engines use a series of cylinders of progressively increasing diameter. These cylinders are designed to divide the work into equal shares for each expansion stage. As with the double expansion engine, if space is at a premium, then two smaller cylinders may be used for the low-pressure stage. Multiple expansion engines typically had the cylinders arranged inline, but various other formations were used. In the late 19th century, the Yarrow-Schlick-Tweedy balancing 'system' was used on some marine triple expansion engines. Y-S-T engines divided the low-pressure expansion stages between two cylinders, one at each end of the engine. This allowed the crankshaft to be better balanced, resulting in a smoother, faster-responding engine which ran with less vibration. This made the 4-cylinder triple-expansion engine popular with large passenger liners (such as the Olympic class), but this was ultimately replaced by the virtually vibration-free turbine engine.[citation needed]

Now answer this question: What are engines using four expansion stages known as?


Please answer a question about the following article about Amazon rainforest:

Deforestation is the conversion of forested areas to non-forested areas. The main sources of deforestation in the Amazon are human settlement and development of the land. Prior to the early 1960s, access to the forest's interior was highly restricted, and the forest remained basically intact. Farms established during the 1960s were based on crop cultivation and the slash and burn method. However, the colonists were unable to manage their fields and the crops because of the loss of soil fertility and weed invasion. The soils in the Amazon are productive for just a short period of time, so farmers are constantly moving to new areas and clearing more land. These farming practices led to deforestation and caused extensive environmental damage. Deforestation is considerable, and areas cleared of forest are visible to the naked eye from outer space.

Acessing the Amazon rainforest was restricted before what era?


Article: Kenya has proven deposits of oil in Turkana and the commercial viability was just discovered. Tullow Oil estimates Kenya's oil reserves to be around 10 billion barrels. Exploration is still continuing to determine if there are more reserves. Kenya currently imports all crude petroleum requirements. Kenya, east Africa's largest economy, has no strategic reserves and relies solely on oil marketers' 21-day oil reserves required under industry regulations. Petroleum accounts for 20% to 25% of the national import bill.

Now answer this question: Where does Kenya have deposits of oil?


The Apollo program succeeded in achieving its goal of manned lunar landing, despite the major setback of a 1967 Apollo 1 cabin fire that killed the entire crew during a prelaunch test. After the first landing, sufficient flight hardware remained for nine follow-on landings with a plan for extended lunar geological and astrophysical exploration. Budget cuts forced the cancellation of three of these. Five of the remaining six missions achieved successful landings, but the Apollo 13 landing was prevented by an oxygen tank explosion in transit to the Moon, which disabled the command spacecraft's propulsion and life support. The crew returned to Earth safely by using the Lunar Module as a "lifeboat" for these functions.

Imperialism
However, in 1883–84 Germany began to build a colonial empire in Africa and the South Pacific, before losing interest in imperialism. Historians have debated exactly why Germany made this sudden and short-lived move.[verification needed] Bismarck was aware that public opinion had started to demand colonies for reasons of German prestige. He was influenced by Hamburg merchants and traders, his neighbors at Friedrichsruh. The establishment of the German colonial empire proceeded smoothly, starting with German New Guinea in 1884.

In 1874, Tesla evaded being drafted into the Austro-Hungarian Army in Smiljan by running away to Tomingaj, near Gračac. There, he explored the mountains in hunter's garb. Tesla said that this contact with nature made him stronger, both physically and mentally. He read many books while in Tomingaj, and later said that Mark Twain's works had helped him to miraculously recover from his earlier illness.

Kublai Khan promoted commercial, scientific, and cultural growth. He supported the merchants of the Silk Road trade network by protecting the Mongol postal system, constructing infrastructure, providing loans that financed trade caravans, and encouraging the circulation of paper banknotes (鈔, Chao). Pax Mongolica, Mongol peace, enabled the spread of technologies, commodities, and culture between China and the West. Kublai expanded the Grand Canal from southern China to Daidu in the north. Mongol rule was cosmopolitan under Kublai Khan. He welcomed foreign visitors to his court, such as the Venetian merchant Marco Polo, who wrote the most influential European account of Yuan China. Marco Polo's travels would later inspire many others like Christopher Columbus to chart a passage to the Far East in search of its legendary wealth.


In 1873, Tesla returned to his birthtown, Smiljan. Shortly after he arrived, Tesla contracted cholera; he was bedridden for nine months and was near death multiple times. Tesla's father, in a moment of despair, promised to send him to the best engineering school if he recovered from the illness (his father had originally wanted him to enter the priesthood).
What disease did Tesla contract in 1873?


The new office of the PM will have power and authority to co-ordinate and supervise the functions of the Government and will be occupied by an elected MP who will be the leader of the party or coalition with majority members in Parliament.

While in-house production had ceased, the BBC hoped to find an independent production company to relaunch the show. Philip Segal, a British expatriate who worked for Columbia Pictures' television arm in the United States, had approached the BBC about such a venture as early as July 1989, while the 26th series was still in production. Segal's negotiations eventually led to a Doctor Who television film, broadcast on the Fox Network in 1996 as a co-production between Fox, Universal Pictures, the BBC and BBC Worldwide. Although the film was successful in the UK (with 9.1 million viewers), it was less so in the United States and did not lead to a series.

In what country was the Doctor Who film not successful enough to spawn a series?


Here is a question about this article: Until 1932 the generally accepted length of the Rhine was 1,230 kilometres (764 miles). In 1932 the German encyclopedia Knaurs Lexikon stated the length as 1,320 kilometres (820 miles), presumably a typographical error. After this number was placed into the authoritative Brockhaus Enzyklopädie, it became generally accepted and found its way into numerous textbooks and official publications. The error was discovered in 2010, and the Dutch Rijkswaterstaat confirms the length at 1,232 kilometres (766 miles).[note 1]
What is the answer to this question: Why was the Rhine measurement changed?

Please answer a question about the following article about Rhine:

At the begin of the Holocene (~11,700 years ago), the Rhine occupied its Late-Glacial valley. As a meandering river, it reworked its ice-age braidplain. As sea-level continued to rise in the Netherlands, the formation of the Holocene Rhine-Meuse delta began (~8,000 years ago). Coeval absolute sea-level rise and tectonic subsidence have strongly influenced delta evolution. Other factors of importance to the shape of the delta are the local tectonic activities of the Peel Boundary Fault, the substrate and geomorphology, as inherited from the Last Glacial and the coastal-marine dynamics, such as barrier and tidal inlet formations.

Where did the Rhine occupy during the Holocene?

Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table and is a highly reactive nonmetal and oxidizing agent that readily forms compounds (notably oxides) with most elements. By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula O
2. Diatomic oxygen gas constitutes 20.8% of the Earth's atmosphere. However, monitoring of atmospheric oxygen levels show a global downward trend, because of fossil-fuel burning. Oxygen is the most abundant element by mass in the Earth's crust as part of oxide compounds such as silicon dioxide, making up almost half of the crust's mass.
Under normal conditions, what do two atoms of oxygen form?


Article: The addition of new rock units, both depositionally and intrusively, often occurs during deformation. Faulting and other deformational processes result in the creation of topographic gradients, causing material on the rock unit that is increasing in elevation to be eroded by hillslopes and channels. These sediments are deposited on the rock unit that is going down. Continual motion along the fault maintains the topographic gradient in spite of the movement of sediment, and continues to create accommodation space for the material to deposit. Deformational events are often also associated with volcanism and igneous activity. Volcanic ashes and lavas accumulate on the surface, and igneous intrusions enter from below. Dikes, long, planar igneous intrusions, enter along cracks, and therefore often form in large numbers in areas that are being actively deformed. This can result in the emplacement of dike swarms, such as those that are observable across the Canadian shield, or rings of dikes around the lava tube of a volcano.

Question: What activity maintains topographic gradients?


Please answer a question about the following article about Economic inequality:

Firstly, certain costs are difficult to avoid and are shared by everyone, such as the costs of housing, pensions, education and health care. If the state does not provide these services, then for those on lower incomes, the costs must be borrowed and often those on lower incomes are those who are worse equipped to manage their finances. Secondly, aspirational consumption describes the process of middle income earners aspiring to achieve the standards of living enjoyed by their wealthier counterparts and one method of achieving this aspiration is by taking on debt. The result leads to even greater inequality and potential economic instability.

What is one method of achieving aspirational consumption?

The Very high-speed Backbone Network Service (vBNS) came on line in April 1995 as part of a National Science Foundation (NSF) sponsored project to provide high-speed interconnection between NSF-sponsored supercomputing centers and select access points in the United States. The network was engineered and operated by MCI Telecommunications under a cooperative agreement with the NSF. By 1998, the vBNS had grown to connect more than 100 universities and research and engineering institutions via 12 national points of presence with DS-3 (45 Mbit/s), OC-3c (155 Mbit/s), and OC-12c (622 Mbit/s) links on an all OC-12c backbone, a substantial engineering feat for that time. The vBNS installed one of the first ever production OC-48c (2.5 Gbit/s) IP links in February 1999 and went on to upgrade the entire backbone to OC-48c.

Oxygen
Reactive oxygen species, such as superoxide ion (O−
2) and hydrogen peroxide (H
2O
2), are dangerous by-products of oxygen use in organisms. Parts of the immune system of higher organisms create peroxide, superoxide, and singlet oxygen to destroy invading microbes. Reactive oxygen species also play an important role in the hypersensitive response of plants against pathogen attack. Oxygen is toxic to obligately anaerobic organisms, which were the dominant form of early life on Earth until O
2 began to accumulate in the atmosphere about 2.5 billion years ago during the Great Oxygenation Event, about a billion years after the first appearance of these organisms.

Q: When did O2 begin to acculturate in the atmosphere?

Nikola Tesla
Tesla was renowned for his achievements and showmanship, eventually earning him a reputation in popular culture as an archetypal "mad scientist". His patents earned him a considerable amount of money, much of which was used to finance his own projects with varying degrees of success.:121,154 He lived most of his life in a series of New York hotels, through his retirement. Tesla died on 7 January 1943. His work fell into relative obscurity after his death, but in 1960 the General Conference on Weights and Measures named the SI unit of magnetic flux density the tesla in his honor. There has been a resurgence in popular interest in Tesla since the 1990s.

Q: What was named "The Tesla" in his honor?

Answer a question about this article:
A construction project is a complex net of contracts and other legal obligations, each of which all parties must carefully consider. A contract is the exchange of a set of obligations between two or more parties, but it is not so simple a matter as trying to get the other side to agree to as much as possible in exchange for as little as possible. The time element in construction means that a delay costs money, and in cases of bottlenecks, the delay can be extremely expensive. Thus, the contracts must be designed to ensure that each side is capable of performing the obligations set out. Contracts that set out clear expectations and clear paths to accomplishing those expectations are far more likely to result in the project flowing smoothly, whereas poorly drafted contracts lead to confusion and collapse.
What does the time element in construction mean?


Free oxygen gas was almost nonexistent in Earth's atmosphere before photosynthetic archaea and bacteria evolved, probably about 3.5 billion years ago. Free oxygen first appeared in significant quantities during the Paleoproterozoic eon (between 3.0 and 2.3 billion years ago). For the first billion years, any free oxygen produced by these organisms combined with dissolved iron in the oceans to form banded iron formations. When such oxygen sinks became saturated, free oxygen began to outgas from the oceans 3–2.7 billion years ago, reaching 10% of its present level around 1.7 billion years ago.
At first, what did oxygen and iron combine to form?

 Seamans' establishment of an ad-hoc committee headed by his special technical assistant Nicholas E. Golovin in July 1961, to recommend a launch vehicle to be used in the Apollo program, represented a turning point in NASA's mission mode decision. This committee recognized that the chosen mode was an important part of the launch vehicle choice, and recommended in favor of a hybrid EOR-LOR mode. Its consideration of LOR —as well as Houbolt's ceaseless work— played an important role in publicizing the workability of the approach. In late 1961 and early 1962, members of the Manned Spacecraft Center began to come around to support LOR, including the newly hired deputy director of the Office of Manned Space Flight, Joseph Shea, who became a champion of LOR. The engineers at Marshall Space Flight Center (MSFC) took longer to become convinced of its merits, but their conversion was announced by Wernher von Braun at a briefing in June 1962.

Who was hired to be the deputy director of the Office of Manned Space Flight?


1973 oil crisis
In response to American aid to Israel, on October 16, 1973, OPEC raised the posted price of oil by 70%, to $5.11 a barrel. The following day, oil ministers agreed to the embargo, a cut in production by five percent from September's output and to continue to cut production in five percent monthly increments until their economic and political objectives were met. On October 19, Nixon requested Congress to appropriate $2.2 billion in emergency aid to Israel, including $1.5 billion in outright grants. George Lenczowski notes, "Military supplies did not exhaust Nixon's eagerness to prevent Israel's collapse...This [$2.2 billion] decision triggered a collective OPEC response." Libya immediately announced it would embargo oil shipments to the United States. Saudi Arabia and the other Arab oil-producing states joined the embargo on October 20, 1973. At their Kuwait meeting, OAPEC proclaimed the embargo that curbed exports to various countries and blocked all oil deliveries to the US as a "principal hostile country".

Q: Why did the oil ministers agree to a cut in oil production?


Article: Early in 1537, Johannes Agricola (1494–1566) – serving at the time as pastor in Luther's birthplace, Eisleben – preached a sermon in which he claimed that God's gospel, not God's moral law (the Ten Commandments), revealed God's wrath to Christians. Based on this sermon and others by Agricola, Luther suspected that Agricola was behind certain anonymous antinomian theses circulating in Wittenberg. These theses asserted that the law is no longer to be taught to Christians but belonged only to city hall. Luther responded to these theses with six series of theses against Agricola and the antinomians, four of which became the basis for disputations between 1538 and 1540. He also responded to these assertions in other writings, such as his 1539 open letter to C. Güttel Against the Antinomians, and his book On the Councils and the Church from the same year.

Question: Who did Luther think was behind the antinomian theses circulating in Wittenberg?


Answer a question about this article:
Hypersensitivity is an immune response that damages the body's own tissues. They are divided into four classes (Type I – IV) based on the mechanisms involved and the time course of the hypersensitive reaction. Type I hypersensitivity is an immediate or anaphylactic reaction, often associated with allergy. Symptoms can range from mild discomfort to death. Type I hypersensitivity is mediated by IgE, which triggers degranulation of mast cells and basophils when cross-linked by antigen. Type II hypersensitivity occurs when antibodies bind to antigens on the patient's own cells, marking them for destruction. This is also called antibody-dependent (or cytotoxic) hypersensitivity, and is mediated by IgG and IgM antibodies. Immune complexes (aggregations of antigens, complement proteins, and IgG and IgM antibodies) deposited in various tissues trigger Type III hypersensitivity reactions. Type IV hypersensitivity (also known as cell-mediated or delayed type hypersensitivity) usually takes between two and three days to develop. Type IV reactions are involved in many autoimmune and infectious diseases, but may also involve contact dermatitis (poison ivy). These reactions are mediated by T cells, monocytes, and macrophages.
What is the chemical that mediates Type 1 hypersensitivity?


To avoid interference with existing VHF television stations in the San Francisco Bay Area and those planned for Chico, Sacramento, Salinas, and Stockton, the Federal Communications Commission decided that Fresno would only have UHF television stations.

Article: Harvard's academic programs operate on a semester calendar beginning in early September and ending in mid-May. Undergraduates typically take four half-courses per term and must maintain a four-course rate average to be considered full-time. In many concentrations, students can elect to pursue a basic program or an honors-eligible program requiring a senior thesis and/or advanced course work. Students graduating in the top 4–5% of the class are awarded degrees summa cum laude, students in the next 15% of the class are awarded magna cum laude, and the next 30% of the class are awarded cum laude. Harvard has chapters of academic honor societies such as Phi Beta Kappa and various committees and departments also award several hundred named prizes annually. Harvard, along with other universities, has been accused of grade inflation, although there is evidence that the quality of the student body and its motivation have also increased. Harvard College reduced the number of students who receive Latin honors from 90% in 2004 to 60% in 2005. Moreover, the honors of "John Harvard Scholar" and "Harvard College Scholar" will now be given only to the top 5 percent and the next 5 percent of each class.

Now answer this question: How many courses must undergraduates maintain for full time status?


Computational complexity theory
Many complexity classes are defined using the concept of a reduction. A reduction is a transformation of one problem into another problem. It captures the informal notion of a problem being at least as difficult as another problem. For instance, if a problem X can be solved using an algorithm for Y, X is no more difficult than Y, and we say that X reduces to Y. There are many different types of reductions, based on the method of reduction, such as Cook reductions, Karp reductions and Levin reductions, and the bound on the complexity of reductions, such as polynomial-time reductions or log-space reductions.

Q: According to reduction, if X and Y can be solved by the same algorithm then X performs what function in relationship to Y?


Article: Since about the year 2000, a growing number of Internet pharmacies have been established worldwide. Many of these pharmacies are similar to community pharmacies, and in fact, many of them are actually operated by brick-and-mortar community pharmacies that serve consumers online and those that walk in their door. The primary difference is the method by which the medications are requested and received. Some customers consider this to be more convenient and private method rather than traveling to a community drugstore where another customer might overhear about the drugs that they take. Internet pharmacies (also known as online pharmacies) are also recommended to some patients by their physicians if they are homebound.

Question: What is one reason a patient might choose an internet pharmacy?

The connection between macroscopic nonconservative forces and microscopic conservative forces is described by detailed treatment with statistical mechanics. In macroscopic closed systems, nonconservative forces act to change the internal energies of the system, and are often associated with the transfer of heat. According to the Second law of thermodynamics, nonconservative forces necessarily result in energy transformations within closed systems from ordered to more random conditions as entropy increases.
What makes energy changes in a closed system?


Article: Edward John Noble, the owner of Life Savers candy, drugstore chain Rexall and New York City radio station WMCA, purchased the network for $8 million. Due to FCC ownership rules, the transaction, which was to include the purchase of three RCA stations by Noble, would require him to resell his station with the FCC's approval. The Commission authorized the transaction on October 12, 1943. Soon afterward, the Blue Network was purchased by the new company Noble founded, the American Broadcasting System. Noble subsequently acquired the rights to the "American Broadcasting Company" name from George B. Storer in 1944; its parent company adopted the corporate name American Broadcasting Companies, Inc. Woods retained his position as president and CEO of ABC until December 1949, and was subsequently promoted to vice-chairman of the board before leaving ABC altogether on June 30, 1951.

Now answer this question: What position did Mark Woods take on at the new American Broadcasting Company?


Article: Plants have two main immune responses—the hypersensitive response, in which infected cells seal themselves off and undergo programmed cell death, and systemic acquired resistance, where infected cells release signals warning the rest of the plant of a pathogen's presence. Chloroplasts stimulate both responses by purposely damaging their photosynthetic system, producing reactive oxygen species. High levels of reactive oxygen species will cause the hypersensitive response. The reactive oxygen species also directly kill any pathogens within the cell. Lower levels of reactive oxygen species initiate systemic acquired resistance, triggering defense-molecule production in the rest of the plant.

The reason for the majority rule is the high risk of a conflict of interest and/or the avoidance of absolute powers. Otherwise, the physician has a financial self-interest in "diagnosing" as many conditions as possible, and in exaggerating their seriousness, because he or she can then sell more medications to the patient. Such self-interest directly conflicts with the patient's interest in obtaining cost-effective medication and avoiding the unnecessary use of medication that may have side-effects. This system reflects much similarity to the checks and balances system of the U.S. and many other governments.[citation needed]
Where might the doctor's self-interest be at odds with the patient's self-interest?

Wilkinson and Kate Pickett have found higher rates of health and social problems (obesity, mental illness, homicides, teenage births, incarceration, child conflict, drug use), and lower rates of social goods (life expectancy by country, educational performance, trust among strangers, women's status, social mobility, even numbers of patents issued) in countries and states with higher inequality. Using statistics from 23 developed countries and the 50 states of the US, they found social/health problems lower in countries like Japan and Finland and states like Utah and New Hampshire with high levels of equality, than in countries (US and UK) and states (Mississippi and New York) with large differences in household income.
What is the answer to this question: Health problems were lower in places with higher levels of what?

Plague was reportedly first introduced to Europe via Genoese traders at the port city of Kaffa in the Crimea in 1347. After a protracted siege, during which the Mongol army under Jani Beg was suffering from the disease, the army catapulted the infected corpses over the city walls of Kaffa to infect the inhabitants. The Genoese traders fled, taking the plague by ship into Sicily and the south of Europe, whence it spread north. Whether or not this hypothesis is accurate, it is clear that several existing conditions such as war, famine, and weather contributed to the severity of the Black Death.

What did the Mongol army throw in their catapults?


Here is a question about this article: One of the rarest items in the collection is the 58 cm high Gloucester Candlestick, dated to c1110, made from gilt bronze; with highly elaborate and intricate intertwining branches containing small figures and inscriptions, it is a tour de force of bronze casting. Also of importance is the Becket Casket dated c1180 to contain relics of St Thomas Becket, made from gilt copper, with enamelled scenes of the saint's martyrdom. Another highlight is the 1351 Reichenau Crozier. The Burghley Nef, a salt-cellar, French, dated 1527–28, uses a nautilus shell to form the hull of a vessel, which rests on the tail of a parcelgilt mermaid, who rests on a hexagonal gilt plinth on six claw-and-ball feet. Both masts have main and top-sails, and battlemented fighting-tops are made from gold. These items are displayed in the new Medieval & Renaissance galleries.
What is the answer to this question: Which material is the Gloucester Candlestick made from?


Article: British victories continued in all theaters in the Annus Mirabilis of 1759, when they finally captured Ticonderoga, James Wolfe defeated Montcalm at Quebec (in a battle that claimed the lives of both commanders), and victory at Fort Niagara successfully cut off the French frontier forts further to the west and south. The victory was made complete in 1760 when, despite losing outside Quebec City in the Battle of Sainte-Foy, the British were able to prevent the arrival of French relief ships in the naval Battle of the Restigouche while armies marched on Montreal from three sides.

Question: What victory at thwarted efforts of French relief ships.

Article: The Panthers defense gave up just 308 points, ranking sixth in the league, while also leading the NFL in interceptions with 24 and boasting four Pro Bowl selections. Pro Bowl defensive tackle Kawann Short led the team in sacks with 11, while also forcing three fumbles and recovering two. Fellow lineman Mario Addison added 6½ sacks. The Panthers line also featured veteran defensive end Jared Allen, a 5-time pro bowler who was the NFL's active career sack leader with 136, along with defensive end Kony Ealy, who had 5 sacks in just 9 starts. Behind them, two of the Panthers three starting linebackers were also selected to play in the Pro Bowl: Thomas Davis and Luke Kuechly. Davis compiled 5½ sacks, four forced fumbles, and four interceptions, while Kuechly led the team in tackles (118) forced two fumbles, and intercepted four passes of his own. Carolina's secondary featured Pro Bowl safety Kurt Coleman, who led the team with a career high seven interceptions, while also racking up 88 tackles and Pro Bowl cornerback Josh Norman, who developed into a shutdown corner during the season and had four interceptions, two of which were returned for touchdowns.

Now answer this question: How many tackles did Luke Kuechly register?


Victoria and Albert Museum
The Victoria and Albert Museum (often abbreviated as the V&A), London, is the world's largest museum of decorative arts and design, housing a permanent collection of over 4.5 million objects. It was founded in 1852 and named after Queen Victoria and Prince Albert. The V&A is located in the Brompton district of the Royal Borough of Kensington and Chelsea, in an area that has become known as "Albertopolis" because of its association with Prince Albert, the Albert Memorial and the major cultural institutions with which he was associated. These include the Natural History Museum, the Science Museum and the Royal Albert Hall. The museum is a non-departmental public body sponsored by the Department for Culture, Media and Sport. Like other national British museums, entrance to the museum has been free since 2001.

Q: Who is the museum named for?


Answer a question about this article:
Kublai's government after 1262 was a compromise between preserving Mongol interests in China and satisfying the demands of his Chinese subjects. He instituted the reforms proposed by his Chinese advisers by centralizing the bureaucracy, expanding the circulation of paper money, and maintaining the traditional monopolies on salt and iron. He restored the Imperial Secretariat and left the local administrative structure of past Chinese dynasties unchanged. However, Kublai rejected plans to revive the Confucian imperial examinations and divided Yuan society into three, later four, classes with the Han Chinese occupying the lowest rank. Kublai's Chinese advisers still wielded significant power in the government, but their official rank was nebulous.
Who would have been the lowest-ranked class?


Article: In humans, this response is activated by complement binding to antibodies that have attached to these microbes or the binding of complement proteins to carbohydrates on the surfaces of microbes. This recognition signal triggers a rapid killing response. The speed of the response is a result of signal amplification that occurs following sequential proteolytic activation of complement molecules, which are also proteases. After complement proteins initially bind to the microbe, they activate their protease activity, which in turn activates other complement proteases, and so on. This produces a catalytic cascade that amplifies the initial signal by controlled positive feedback. The cascade results in the production of peptides that attract immune cells, increase vascular permeability, and opsonize (coat) the surface of a pathogen, marking it for destruction. This deposition of complement can also kill cells directly by disrupting their plasma membrane.

Now answer this question: The speed of the killing response of the human immune system is a product of what process?


What is the title of this article:

Datanet 1 was the public switched data network operated by the Dutch PTT Telecom (now known as KPN). Strictly speaking Datanet 1 only referred to the network and the connected users via leased lines (using the X.121 DNIC 2041), the name also referred to the public PAD service Telepad (using the DNIC 2049). And because the main Videotex service used the network and modified PAD devices as infrastructure the name Datanet 1 was used for these services as well. Although this use of the name was incorrect all these services were managed by the same people within one department of KPN contributed to the confusion.


Please answer a question about the following article about Prime number:

Several public-key cryptography algorithms, such as RSA and the Diffie–Hellman key exchange, are based on large prime numbers (for example, 512-bit primes are frequently used for RSA and 1024-bit primes are typical for Diffie–Hellman.). RSA relies on the assumption that it is much easier (i.e., more efficient) to perform the multiplication of two (large) numbers x and y than to calculate x and y (assumed coprime) if only the product xy is known. The Diffie–Hellman key exchange relies on the fact that there are efficient algorithms for modular exponentiation, while the reverse operation the discrete logarithm is thought to be a hard problem.

How many bits are typically used in the primes for the Diffie–Hellman key exchange?


Article: Iqbal expressed fears that not only would secularism and secular nationalism weaken the spiritual foundations of Islam and Muslim society, but that India's Hindu-majority population would crowd out Muslim heritage, culture and political influence. In his travels to Egypt, Afghanistan, Palestine and Syria, he promoted ideas of greater Islamic political co-operation and unity, calling for the shedding of nationalist differences. Sir Muhammad Iqbal was elected president of the Muslim League in 1930 at its session in Allahabad as well as for the session in Lahore in 1932. In his Allahabad Address on 29 December 1930, Iqbal outlined a vision of an independent state for Muslim-majority provinces in northwestern India. This address later inspired the Pakistan movement.

Now answer this question: Iqbal worried that India's mostly Hindu population would do what to Muslim heritage and culture?


Please answer a question about the following article about Warsaw:

After the German Invasion of Poland on 1 September 1939 began the Second World War, Warsaw was defended till September 27. Central Poland, including Warsaw, came under the rule of the General Government, a German Nazi colonial administration. All higher education institutions were immediately closed and Warsaw's entire Jewish population – several hundred thousand, some 30% of the city – herded into the Warsaw Ghetto. The city would become the centre of urban resistance to Nazi rule in occupied Europe. When the order came to annihilate the ghetto as part of Hitler's "Final Solution" on 19 April 1943, Jewish fighters launched the Warsaw Ghetto Uprising. Despite being heavily outgunned and outnumbered, the Ghetto held out for almost a month. When the fighting ended, almost all survivors were massacred, with only a few managing to escape or hide.

When did Hitler order the annihilation of the Warsaw Ghetto?

Article: From the late 1340s onwards, people in the countryside suffered from frequent natural disasters such as droughts, floods and the resulting famines, and the government's lack of effective policy led to a loss of popular support. In 1351, the Red Turban Rebellion started and grew into a nationwide uprising. In 1354, when Toghtogha led a large army to crush the Red Turban rebels, Toghun Temür suddenly dismissed him for fear of betrayal. This resulted in Toghun Temür's restoration of power on the one hand and a rapid weakening of the central government on the other. He had no choice but to rely on local warlords' military power, and gradually lost his interest in politics and ceased to intervene in political struggles. He fled north to Shangdu from Khanbaliq (present-day Beijing) in 1368 after the approach of the forces of the Míng dynasty (1368–1644), founded by Zhu Yuanzhang in the south. He had tried to regain Khanbaliq, which eventually failed; he died in Yingchang (located in present-day Inner Mongolia) two years later (1370). Yingchang was seized by the Ming shortly after his death. Some royal family members still lived in Henan today.

Now answer this question: What uprising began in 1351?


Answer a question about this article:
The Yuan undertook extensive public works. Among Kublai Khan's top engineers and scientists was the astronomer Guo Shoujing, who was tasked with many public works projects and helped the Yuan reform the lunisolar calendar to provide an accuracy of 365.2425 days of the year, which was only 26 seconds off the modern Gregorian calendar's measurement. Road and water communications were reorganized and improved. To provide against possible famines, granaries were ordered built throughout the empire. The city of Beijing was rebuilt with new palace grounds that included artificial lakes, hills and mountains, and parks. During the Yuan period, Beijing became the terminus of the Grand Canal of China, which was completely renovated. These commercially oriented improvements encouraged overland and maritime commerce throughout Asia and facilitated direct Chinese contacts with Europe. Chinese travelers to the West were able to provide assistance in such areas as hydraulic engineering. Contacts with the West also brought the introduction to China of a major food crop, sorghum, along with other foreign food products and methods of preparation.
What astronomer worked for Kublai?


European Union law
Following the election of the UK Labour Party to government in 1997, the UK formally subscribed to the Agreement on Social Policy, which allowed it to be included with minor amendments as the Social Chapter of the 1997 Treaty of Amsterdam. The UK subsequently adopted the main legislation previously agreed under the Agreement on Social Policy, the 1994 Works Council Directive, which required workforce consultation in businesses, and the 1996 Parental Leave Directive. In the 10 years following the 1997 Treaty of Amsterdam and adoption of the Social Chapter the European Union has undertaken policy initiatives in various social policy areas, including labour and industry relations, equal opportunity, health and safety, public health, protection of children, the disabled and elderly, poverty, migrant workers, education, training and youth.

Q: What did the Works Council Directive require?


Article: Oxygen toxicity to the lungs and central nervous system can also occur in deep scuba diving and surface supplied diving. Prolonged breathing of an air mixture with an O
2 partial pressure more than 60 kPa can eventually lead to permanent pulmonary fibrosis. Exposure to a O
2 partial pressures greater than 160 kPa (about 1.6 atm) may lead to convulsions (normally fatal for divers). Acute oxygen toxicity (causing seizures, its most feared effect for divers) can occur by breathing an air mixture with 21% O
2 at 66 m or more of depth; the same thing can occur by breathing 100% O
2 at only 6 m.

Question: What is the most feared condition that divers want to avoid?


Please answer a question about the following article about Fresno, California:

While many homes in the neighborhood date back to the 1930s or before, the neighborhood is also home to several public housing developments built between the 1960s and 1990s by the Fresno Housing Authority. The US Department of Housing and Urban Development has also built small subdivisions of single-family homes in the area for purchase by low-income working families. There have been numerous attempts to revitalize the neighborhood, including the construction of a modern shopping center on the corner of Fresno and B streets, an aborted attempt to build luxury homes and a golf course on the western edge of the neighborhood, and some new section 8 apartments have been built along Church Ave west of Elm St. Cargill Meat Solutions and Foster Farms both have large processing facilities in the neighborhood, and the stench from these (and other small industrial facilities) has long plagued area residents. The Fresno Chandler Executive Airport is also on the West Side. Due to its position on the edge of the city and years of neglect by developers, is not a true "inner-city" neighborhood, and there are many vacant lots, strawberry fields and vineyards throughout the neighborhood. The neighborhood has very little retail activity, aside from the area near Fresno Street and State Route 99 Freeway (Kearney Palm Shopping Center, built in the late 1990s) and small corner markets scattered throughout.

On which corner is the shopping center located?

In 1888, the editor of Electrical World magazine, Thomas Commerford Martin (a friend and publicist), arranged for Tesla to demonstrate his alternating current system, including his induction motor, at the American Institute of Electrical Engineers (now IEEE). Engineers working for the Westinghouse Electric & Manufacturing Company reported to George Westinghouse that Tesla had a viable AC motor and related power system — something for which Westinghouse had been trying to secure patents. Westinghouse looked into getting a patent on a similar commutator-less, rotating magnetic field-based induction motor presented in a paper in March 1888 by the Italian physicist Galileo Ferraris, but decided Tesla's patent would probably control the market.

Who was Thomas Commerford Martin?


Major roads in the area include the A1 (Gateshead Newcastle Western Bypass), stretching north to Edinburgh and south to London; the A19 heading south past Sunderland and Middlesbrough to York and Doncaster; the A69 heading west to Carlisle; the A696, which becomes the A68 heads past Newcastle Airport and up through central Northumberland and central Scottish Borders, the A167, the old "Great North Road", heading south to Gateshead, Chester-le-Street, Durham and Darlington; and the A1058 "Coast Road", which runs from Jesmond to the east coast between Tynemouth and Cullercoats. Many of these designations are recent—upon completion of the Western Bypass, and its designation as the new line of the A1, the roads between this and the A1's former alignment through the Tyne Tunnel were renumbered, with many city centre roads changing from a 6-prefix to their present 1-prefix numbers. In November 2011 the capacity of the Tyne Tunnel was increased when a project to build a second road tunnel and refurbish the first tunnel was completed.

The outcome was one of the most significant developments in a century of Anglo-French conflict. France ceded its territory east of the Mississippi to Great Britain. It ceded French Louisiana west of the Mississippi River (including New Orleans) to its ally Spain, in compensation for Spain's loss to Britain of Florida (Spain had ceded this to Britain in exchange for the return of Havana, Cuba). France's colonial presence north of the Caribbean was reduced to the islands of Saint Pierre and Miquelon, confirming Britain's position as the dominant colonial power in eastern North America.

What territory was ceded to Britain?

Another important role of the immune system is to identify and eliminate tumors. This is called immune surveillance. The transformed cells of tumors express antigens that are not found on normal cells. To the immune system, these antigens appear foreign, and their presence causes immune cells to attack the transformed tumor cells. The antigens expressed by tumors have several sources; some are derived from oncogenic viruses like human papillomavirus, which causes cervical cancer, while others are the organism's own proteins that occur at low levels in normal cells but reach high levels in tumor cells. One example is an enzyme called tyrosinase that, when expressed at high levels, transforms certain skin cells (e.g. melanocytes) into tumors called melanomas. A third possible source of tumor antigens are proteins normally important for regulating cell growth and survival, that commonly mutate into cancer inducing molecules called oncogenes.

What is an example of an enzyme that can transform skin cells into tumors when expressed at high levels?


French and Indian War
In Europe, the North American theater of the Seven Years' War usually is not given a separate name. The entire international conflict is known as the Seven Years' War. "Seven Years" refers to events in Europe, from the official declaration of war in 1756 to the signing of the peace treaty in 1763. These dates do not correspond with the fighting on mainland North America, where the fighting between the two colonial powers was largely concluded in six years, from the Battle of Jumonville Glen in 1754 to the capture of Montreal in 1760.

Q: What was first battle in 1754?


Please answer a question about the following article about Warsaw:

The first historical reference to Warsaw dates back to the year 1313, at a time when Kraków served as the Polish capital city. Due to its central location between the Polish–Lithuanian Commonwealth's capitals of Kraków and Vilnius, Warsaw became the capital of the Commonwealth and of the Crown of the Kingdom of Poland when King Sigismund III Vasa moved his court from Kraków to Warsaw in 1596. After the Third Partition of Poland in 1795, Warsaw was incorporated into the Kingdom of Prussia. In 1806 during the Napoleonic Wars, the city became the official capital of the Grand Duchy of Warsaw, a puppet state of the First French Empire established by Napoleon Bonaparte. In accordance with the decisions of the Congress of Vienna, the Russian Empire annexed Warsaw in 1815 and it became part of the "Congress Kingdom". Only in 1918 did it regain independence from the foreign rule and emerge as a new capital of the independent Republic of Poland. The German invasion in 1939, the massacre of the Jewish population and deportations to concentration camps led to the uprising in the Warsaw ghetto in 1943 and to the major and devastating Warsaw Uprising between August and October 1944. Warsaw gained the title of the "Phoenix City" because it has survived many wars, conflicts and invasions throughout its long history. Most notably, the city required painstaking rebuilding after the extensive damage it suffered in World War II, which destroyed 85% of its buildings. On 9 November 1940, the city was awarded Poland's highest military decoration for heroism, the Virtuti Militari, during the Siege of Warsaw (1939).

When is the first reference in history to Warsaw?


Answer a question about this article:
It became clear that managing the Apollo program would exceed the capabilities of Robert R. Gilruth's Space Task Group, which had been directing the nation's manned space program from NASA's Langley Research Center. So Gilruth was given authority to grow his organization into a new NASA center, the Manned Spacecraft Center (MSC). A site was chosen in Houston, Texas, on land donated by Rice University, and Administrator Webb announced the conversion on September 19, 1961. It was also clear NASA would soon outgrow its practice of controlling missions from its Cape Canaveral Air Force Station launch facilities in Florida, so a new Mission Control Center would be included in the MSC.
Where was the Space Task Group located?

Answer a question about this article:
During the Southern Song dynasty the descendant of Confucius at Qufu, the Duke Yansheng Kong Duanyou fled south with the Song Emperor to Quzhou, while the newly established Jin dynasty (1115–1234) in the north appointed Kong Duanyou's brother Kong Duancao who remained in Qufu as Duke Yansheng. From that time up until the Yuan dynasty, there were two Duke Yanshengs, once in the north in Qufu and the other in the south at Quzhou. During the Yuan dynasty, the Emperor Kublai Khan invited the southern Duke Yansheng Kong Zhu to return to Qufu. Kong Zhu refused, and gave up the title, so the northern branch of the family kept the title of Duke Yansheng. The southern branch still remained in Quzhou where they lived to this day. Confucius's descendants in Quzhou alone number 30,000. During the Yuan dynasty, one of Confucius' descendants moved from China to Goryeo era Korea and established a branch of the family there after marrying a Korean woman.
Who did Duke Yansheng Kong Duanyou flee with?


Please answer a question about the following article about Huguenot:

In 1700 several hundred French Huguenots migrated from England to the colony of Virginia, where the English Crown had promised them land grants in Lower Norfolk County. When they arrived, colonial authorities offered them instead land 20 miles above the falls of the James River, at the abandoned Monacan village known as Manakin Town, now in Powhatan County. Some settlers landed in present-day Chesterfield County. On 12 May 1705, the Virginia General Assembly passed an act to naturalise the 148 Huguenots still resident at Manakintown. Of the original 390 settlers in the isolated settlement, many had died; others lived outside town on farms in the English style; and others moved to different areas. Gradually they intermarried with their English neighbors. Through the 18th and 19th centuries, descendants of the French migrated west into the Piedmont, and across the Appalachian Mountains into the West of what became Kentucky, Tennessee, Missouri, and other states. In the Manakintown area, the Huguenot Memorial Bridge across the James River and Huguenot Road were named in their honor, as were many local features, including several schools, including Huguenot High School.

What town was actually granted to the Huguenots on arrival?


Here is a question about this article: Around 2.5 million years ago (ending 11,600 years ago) was the geological period of the Ice Ages. Since approximately 600,000 years ago, six major Ice Ages have occurred, in which sea level dropped 120 m (390 ft) and much of the continental margins became exposed. In the Early Pleistocene, the Rhine followed a course to the northwest, through the present North Sea. During the so-called Anglian glaciation (~450,000 yr BP, marine oxygen isotope stage 12), the northern part of the present North Sea was blocked by the ice and a large lake developed, that overflowed through the English Channel. This caused the Rhine's course to be diverted through the English Channel. Since then, during glacial times, the river mouth was located offshore of Brest, France and rivers, like the Thames and the Seine, became tributaries to the Rhine. During interglacials, when sea level rose to approximately the present level, the Rhine built deltas, in what is now the Netherlands.
What is the answer to this question: How far did the sea level drop in the ice ages?

The Amazon rainforest (Portuguese: Floresta Amazônica or Amazônia; Spanish: Selva Amazónica, Amazonía or usually Amazonia; French: Forêt amazonienne; Dutch: Amazoneregenwoud), also known in English as Amazonia or the Amazon Jungle, is a moist broadleaf forest that covers most of the Amazon basin of South America. This basin encompasses 7,000,000 square kilometres (2,700,000 sq mi), of which 5,500,000 square kilometres (2,100,000 sq mi) are covered by the rainforest. This region includes territory belonging to nine nations. The majority of the forest is contained within Brazil, with 60% of the rainforest, followed by Peru with 13%, Colombia with 10%, and with minor amounts in Venezuela, Ecuador, Bolivia, Guyana, Suriname and French Guiana. States or departments in four nations contain "Amazonas" in their names. The Amazon represents over half of the planet's remaining rainforests, and comprises the largest and most biodiverse tract of tropical rainforest in the world, with an estimated 390 billion individual trees divided into 16,000 species.
What kind of forest is the Amazon rainforest?

Individual Huguenots settled at the Cape of Good Hope from as early as 1671 with the arrival of François Villion (Viljoen). The first Huguenot to arrive at the Cape of Good Hope was however Maria de la Queillerie, wife of commander Jan van Riebeeck (and daughter of a Walloon church minister), who arrived on 6 April 1652 to establish a settlement at what is today Cape Town. The couple left for the Far East ten years later. On 31 December 1687 the first organised group of Huguenots set sail from the Netherlands to the Dutch East India Company post at the Cape of Good Hope. The largest portion of the Huguenots to settle in the Cape arrived between 1688 and 1689 in seven ships as part of the organised migration, but quite a few arrived as late as 1700; thereafter, the numbers declined and only small groups arrived at a time.

Where did the first Huguenot colonists settle?


Here is a question about this article: James Hutton is often viewed as the first modern geologist. In 1785 he presented a paper entitled Theory of the Earth to the Royal Society of Edinburgh. In his paper, he explained his theory that the Earth must be much older than had previously been supposed in order to allow enough time for mountains to be eroded and for sediments to form new rocks at the bottom of the sea, which in turn were raised up to become dry land. Hutton published a two-volume version of his ideas in 1795 (Vol. 1, Vol. 2).
What is the answer to this question: In 1785 James Hutton presented what paper to the Royal Society of Edinburgh?


Here is a question about this article: On April 20, Kennedy sent a memo to Vice President Lyndon B. Johnson, asking Johnson to look into the status of America's space program, and into programs that could offer NASA the opportunity to catch up. Johnson responded approximately one week later, concluding that "we are neither making maximum effort nor achieving results necessary if this country is to reach a position of leadership." His memo concluded that a manned Moon landing was far enough in the future that it was likely the United States would achieve it first.
What is the answer to this question: What was the general consensus Johnson came to regarding America's progress on going to space and reaching a position of leadership?


Here is a question about this article: Extension causes the rock units as a whole to become longer and thinner. This is primarily accomplished through normal faulting and through the ductile stretching and thinning. Normal faults drop rock units that are higher below those that are lower. This typically results in younger units being placed below older units. Stretching of units can result in their thinning; in fact, there is a location within the Maria Fold and Thrust Belt in which the entire sedimentary sequence of the Grand Canyon can be seen over a length of less than a meter. Rocks at the depth to be ductilely stretched are often also metamorphosed. These stretched rocks can also pinch into lenses, known as boudins, after the French word for "sausage", because of their visual similarity.
What is the answer to this question: This causes the rock unit as a whole to become longer and thinner.


Answer a question about this article:
Following their loss in the divisional round of the previous season's playoffs, the Denver Broncos underwent numerous coaching changes, including a mutual parting with head coach John Fox (who had won four divisional championships in his four years as Broncos head coach), and the hiring of Gary Kubiak as the new head coach. Under Kubiak, the Broncos planned to install a run-oriented offense with zone blocking to blend in with quarterback Peyton Manning's shotgun passing skills, but struggled with numerous changes and injuries to the offensive line, as well as Manning having his worst statistical season since his rookie year with the Indianapolis Colts in 1998, due to a plantar fasciitis injury in his heel that he had suffered since the summer, and the simple fact that Manning was getting old, as he turned 39 in the 2015 off-season. Although the team had a 7–0 start, Manning led the NFL in interceptions. In week 10, Manning suffered a partial tear of the plantar fasciitis in his left foot. He set the NFL's all-time record for career passing yards in this game, but was benched after throwing four interceptions in favor of backup quarterback Brock Osweiler, who took over as the starter for most of the remainder of the regular season. Osweiler was injured, however, leading to Manning's return during the Week 17 regular season finale, where the Broncos were losing 13–7 against the 4–11 San Diego Chargers, resulting in Manning re-claiming the starting quarterback position for the playoffs by leading the team to a key 27–20 win that enabled the team to clinch the number one overall AFC seed. Under defensive coordinator Wade Phillips, the Broncos' defense ranked number one in total yards allowed, passing yards allowed and sacks, and like the previous three seasons, the team has continued to set numerous individual, league and franchise records. With the defense carrying the team despite the issues with the offense, the Broncos finished the regular season with a 12–4 record and earned home-field advantage throughout the AFC playoffs.
Who was the quarterback for the Broncos 2015 season?

Apollo 5 (AS-204) was the first unmanned test flight of LM in Earth orbit, launched from pad 37 on January 22, 1968, by the Saturn IB that would have been used for Apollo 1. The LM engines were successfully test-fired and restarted, despite a computer programming error which cut short the first descent stage firing. The ascent engine was fired in abort mode, known as a "fire-in-the-hole" test, where it was lit simultaneously with jettison of the descent stage. Although Grumman wanted a second unmanned test, George Low decided the next LM flight would be manned.


Following the utilitarian principle of seeking the greatest good for the greatest number – economic inequality is problematic. A house that provides less utility to a millionaire as a summer home than it would to a homeless family of five, is an example of reduced "distributive efficiency" within society, that decreases marginal utility of wealth and thus the sum total of personal utility. An additional dollar spent by a poor person will go to things providing a great deal of utility to that person, such as basic necessities like food, water, and healthcare; while, an additional dollar spent by a much richer person will very likely go to luxury items providing relatively less utility to that person. Thus, the marginal utility of wealth per person ("the additional dollar") decreases as a person becomes richer. From this standpoint, for any given amount of wealth in society, a society with more equality will have higher aggregate utility. Some studies have found evidence for this theory, noting that in societies where inequality is lower, population-wide satisfaction and happiness tend to be higher.
A dollar spent by a poor person is likely to provide what for them?

However, this oft-quoted saying of Tetzel was by no means representative of contemporary Catholic teaching on indulgences, but rather a reflection of his capacity to exaggerate. Yet if Tetzel overstated the matter in regard to indulgences for the dead, his teaching on indulgences for the living was in line with Catholic dogma of the time.


Article: To fix carbon dioxide into sugar molecules in the process of photosynthesis, chloroplasts use an enzyme called rubisco. Rubisco has a problem—it has trouble distinguishing between carbon dioxide and oxygen, so at high oxygen concentrations, rubisco starts accidentally adding oxygen to sugar precursors. This has the end result of ATP energy being wasted and CO2 being released, all with no sugar being produced. This is a big problem, since O2 is produced by the initial light reactions of photosynthesis, causing issues down the line in the Calvin cycle which uses rubisco.

Question: What process down the line does rubisco's flaw interfere with?


Article: On June 16, 2007, ABC began to phase in a new imaging campaign for the upcoming 2007–08 season, "Start Here". Also developed by Troika, the on-air design was intended to emphasize the availability of ABC content across multiple platforms (in particular, using a system of icons representing different devices, such as television, computers and mobile devices), and "simplify and bring a lot more consistency and continuity to the visual representation of ABC". The ABC logo was also significantly redesigned as part of the transition, with a glossy "ball" effect that was specifically designed for HD. On-air, the logo was accompanied by animated water and ribbon effects. Red ribbons were used to represent the entertainment division, while blue ribbons were used for ABC News.

Question: Blue ribbons in the logo were used to represent which division of ABC?


Construction
Mortgage bankers, accountants, and cost engineers are likely participants in creating an overall plan for the financial management of the building construction project. The presence of the mortgage banker is highly likely, even in relatively small projects since the owner's equity in the property is the most obvious source of funding for a building project. Accountants act to study the expected monetary flow over the life of the project and to monitor the payouts throughout the process. Cost engineers and estimators apply expertise to relate the work and materials involved to a proper valuation. Cost overruns with government projects have occurred when the contractor identified change orders or project changes that increased costs, which are not subject to competition from other firms as they have already been eliminated from consideration after the initial bid.

Q: Who studies the expected monetary flow over the life of the project and to monitor the payouts throughout the process?

Before World War I, Tesla sought overseas investors. After the war started, Tesla lost the funding he was receiving from his patents in European countries. Eventually, he sold Wardenclyffe for $20,000 ($472,500 in today's dollars). In 1917, around the time that the Wardenclyffe Tower was demolished by Boldt to make the land a more viable real estate asset, Tesla received AIEE's highest honor, the Edison Medal.
What award was given to Tesla?


Answer a question about this article:
The original theme was composed by Ron Grainer and realised by Delia Derbyshire of the BBC Radiophonic Workshop, with assistance from Dick Mills. The various parts were built up using musique concrète techniques, by creating tape loops of an individually struck piano string and individual test oscillators and filters. The Derbyshire arrangement served, with minor edits, as the theme tune up to the end of season 17 (1979–80). It is regarded as a significant and innovative piece of electronic music, recorded well before the availability of commercial synthesisers or multitrack mixers. Each note was individually created by cutting, splicing, speeding up and slowing down segments of analogue tape containing recordings of a single plucked string, white noise, and the simple harmonic waveforms of test-tone oscillators, intended for calibrating equipment and rooms, not creating music. New techniques were invented to allow mixing of the music, as this was before the era of multitrack tape machines. On hearing the finished result, Grainer asked, "Did I write that?"[citation needed]
When was the last season that this original theme was used?


Article: The Taliban were spawned by the thousands of madrasahs the Deobandi movement established for impoverished Afghan refugees and supported by governmental and religious groups in neighboring Pakistan. The Taliban differed from other Islamist movements to the point where they might be more properly described as Islamic fundamentalist or neofundamentalist, interested in spreading "an idealized and systematized version of conservative tribal village customs" under the label of Sharia to an entire country. Their ideology was also described as being influenced by Wahhabism, and the extremist jihadism of their guest Osama bin Laden.

Now answer this question: Thousands of madrasahs spawned what organization?


Article: Shi Tianze was a Han Chinese who lived in the Jin dynasty. Interethnic marriage between Han and Jurchen became common at this time. His father was Shi Bingzhi (史秉直, Shih Ping-chih). Shi Bingzhi was married to a Jurchen woman (surname Na-ho) and a Han Chinese woman (surname Chang); it is unknown which of them was Shi Tianze's mother. Shi Tianze was married to two Jurchen women, a Han Chinese woman, and a Korean woman, and his son Shi Gang was born to one of his Jurchen wives. The surnames of his Jurchen wives were Mo-nien and Na-ho; the surname of his Korean wife was Li; and the surname of his Han Chinese wife was Shi. Shi Tianze defected to Mongol forces upon their invasion of the Jin dynasty. His son Shi Gang married a Kerait woman; the Kerait were Mongolified Turkic people and were considered part of the "Mongol nation". Shi Tianze (Shih T'ien-tse), Zhang Rou (Chang Jou, 張柔), and Yan Shi (Yen Shih, 嚴實) and other high ranking Chinese who served in the Jin dynasty and defected to the Mongols helped build the structure for the administration of the new state. Chagaan (Tsagaan) and Zhang Rou jointly launched an attack on the Song dynasty ordered by Töregene Khatun.

The idea was to create a network of wholly and partially owned channels, and affiliates to rebroadcast the network's programs. In 1959, this rerun activity was completed with program syndication, with ABC Films selling programs to networks not owned by ABC. The arrival of satellite television ended the need for ABC to hold interests in other countries; many governments also wanted to increase their independence and strengthen legislation to limit foreign ownership of broadcasting properties. As a result, ABC was forced to sell all of its interests in international networks, mainly in Japan and Latin America, in the 1970s.

When did ABC Films begin selling programs to other networks?

In 1870, Tesla moved to Karlovac, to attend school at the Higher Real Gymnasium, where he was profoundly influenced by a math teacher Martin Sekulić.:32 The classes were held in German, as it was a school within the Austro-Hungarian Military Frontier. Tesla was able to perform integral calculus in his head, which prompted his teachers to believe that he was cheating. He finished a four-year term in three years, graduating in 1873.:33
What could Tesla perform in his head?


In the United States, the game was televised by CBS, as part of a cycle between the three main broadcast television partners of the NFL. The network's lead broadcast team of Jim Nantz and Phil Simms called the contest, with Tracy Wolfson and Evan Washburn on the sidelines. CBS introduced new features during the telecast, including pylon cameras and microphones along with EyeVision 360—an array of 36 cameras along the upper deck that can be used to provide a 360-degree view of plays and "bullet time" effects. (An earlier version of EyeVision was last used in Super Bowl XXXV; for Super Bowl 50, the cameras were upgraded to 5K resolution.)
Who, with Jim Nantz, was a member of the game's lead broadcast team?

Warsaw
One of the most famous people born in Warsaw was Maria Skłodowska-Curie, who achieved international recognition for her research on radioactivity and was the first female recipient of the Nobel Prize. Famous musicians include Władysław Szpilman and Frédéric Chopin. Though Chopin was born in the village of Żelazowa Wola, about 60 km (37 mi) from Warsaw, he moved to the city with his family when he was seven months old. Casimir Pulaski, a Polish general and hero of the American Revolutionary War, was born here in 1745.

Q: How old was Chopin when he moved to Warsaw with his family?


Article: In the Middle East, and particularly in Iran, Genghis Khan is almost universally condemned as a destructive and genocidal warlord who caused enormous damage and destruction to the population of these areas. Steven R. Ward wrote that "Overall, the Mongol violence and depredations killed up to three-fourths of the population of the Iranian Plateau, possibly 10 to 15 million people. Some historians have estimated that Iran's population did not again reach its pre-Mongol levels until the mid-20th century."

Question: How many people do historians estimate Genghis Khan killed in the Iranian Plateau?


Hyperbaric (high-pressure) medicine uses special oxygen chambers to increase the partial pressure of O
2 around the patient and, when needed, the medical staff. Carbon monoxide poisoning, gas gangrene, and decompression sickness (the 'bends') are sometimes treated using these devices. Increased O
2 concentration in the lungs helps to displace carbon monoxide from the heme group of hemoglobin. Oxygen gas is poisonous to the anaerobic bacteria that cause gas gangrene, so increasing its partial pressure helps kill them. Decompression sickness occurs in divers who decompress too quickly after a dive, resulting in bubbles of inert gas, mostly nitrogen and helium, forming in their blood. Increasing the pressure of O
2 as soon as possible is part of the treatment.
What occurs after a dive in which a diver decompresses too quickly?


There is evidence that there have been significant changes in Amazon rainforest vegetation over the last 21,000 years through the Last Glacial Maximum (LGM) and subsequent deglaciation. Analyses of sediment deposits from Amazon basin paleolakes and from the Amazon Fan indicate that rainfall in the basin during the LGM was lower than for the present, and this was almost certainly associated with reduced moist tropical vegetation cover in the basin. There is debate, however, over how extensive this reduction was. Some scientists argue that the rainforest was reduced to small, isolated refugia separated by open forest and grassland; other scientists argue that the rainforest remained largely intact but extended less far to the north, south, and east than is seen today. This debate has proved difficult to resolve because the practical limitations of working in the rainforest mean that data sampling is biased away from the center of the Amazon basin, and both explanations are reasonably well supported by the available data.
Analysis of what kind of deposits from the Amazon Fan indicates a change in rainfall in the Amazon basin?

Article: 30 US states have banned corporal punishment, the others (mostly in the South) have not. It is still used to a significant (though declining) degree in some public schools in Alabama, Arkansas, Georgia, Louisiana, Mississippi, Oklahoma, Tennessee and Texas. Private schools in these and most other states may also use it. Corporal punishment in American schools is administered to the seat of the student's trousers or skirt with a specially made wooden paddle. This often used to take place in the classroom or hallway, but nowadays the punishment is usually given privately in the principal's office.

Question: How many US states do no practice corporal punishment?

The quick and decisive defeat of the Arab troops during the Six-Day War by Israeli troops constituted a pivotal event in the Arab Muslim world. The defeat along with economic stagnation in the defeated countries, was blamed on the secular Arab nationalism of the ruling regimes. A steep and steady decline in the popularity and credibility of secular, socialist and nationalist politics ensued. Ba'athism, Arab socialism, and Arab nationalism suffered, and different democratic and anti-democratic Islamist movements inspired by Maududi and Sayyid Qutb gained ground.


Answer a question about this article:
The concept environmental determinism served as a moral justification for domination of certain territories and peoples. It was believed that a certain person's behaviours were determined by the environment in which they lived and thus validated their domination. For example, people living in tropical environments were seen as "less civilized" therefore justifying colonial control as a civilizing mission. Across the three waves of European colonialism (first in the Americas, second in Asia and lastly in Africa), environmental determinism was used to categorically place indigenous people in a racial hierarchy. This takes two forms, orientalism and tropicality.
What were the two forms of environmental determinism?

Article: Super Bowl 50 featured numerous records from individuals and teams. Denver won despite being massively outgained in total yards (315 to 194) and first downs (21 to 11). Their 194 yards and 11 first downs were both the lowest totals ever by a Super Bowl winning team. The previous record was 244 yards by the Baltimore Ravens in Super Bowl XXXV. Only seven other teams had ever gained less than 200 yards in a Super Bowl, and all of them had lost. The Broncos' seven sacks tied a Super Bowl record set by the Chicago Bears in Super Bowl XX. Kony Ealy tied a Super Bowl record with three sacks. Jordan Norwood's 61-yard punt return set a new record, surpassing the old record of 45 yards set by John Taylor in Super Bowl XXIII. Denver was just 1-of-14 on third down, while Carolina was barely better at 3-of-15. The two teams' combined third down conversion percentage of 13.8 was a Super Bowl low. Manning and Newton had quarterback passer ratings of 56.6 and 55.4, respectively, and their added total of 112 is a record lowest aggregate passer rating for a Super Bowl. Manning became the oldest quarterback ever to win a Super Bowl at age 39, and the first quarterback ever to win a Super Bowl with two different teams, while Gary Kubiak became the first head coach to win a Super Bowl with the same franchise he went to the Super Bowl with as a player.

Now answer this question: How many teams has Manning won the Super Bowl with?


Answer a question about this article:
In cpDNA, there are several A → G deamination gradients. DNA becomes susceptible to deamination events when it is single stranded. When replication forks form, the strand not being copied is single stranded, and thus at risk for A → G deamination. Therefore, gradients in deamination indicate that replication forks were most likely present and the direction that they initially opened (the highest gradient is most likely nearest the start site because it was single stranded for the longest amount of time). This mechanism is still the leading theory today; however, a second theory suggests that most cpDNA is actually linear and replicates through homologous recombination. It further contends that only a minority of the genetic material is kept in circular chromosomes while the rest is in branched, linear, or other complex structures.
How does the secondary theory say most cpDNA is structured?


Article: After a chloroplast polypeptide is synthesized on a ribosome in the cytosol, an enzyme specific to chloroplast proteins phosphorylates, or adds a phosphate group to many (but not all) of them in their transit sequences. Phosphorylation helps many proteins bind the polypeptide, keeping it from folding prematurely. This is important because it prevents chloroplast proteins from assuming their active form and carrying out their chloroplast functions in the wrong place—the cytosol. At the same time, they have to keep just enough shape so that they can be recognized by the chloroplast. These proteins also help the polypeptide get imported into the chloroplast.

Now answer this question: Where is the chloroplast polypeptide synthesized?


Article: Starting in 1894, Tesla began investigating what he referred to as radiant energy of "invisible" kinds after he had noticed damaged film in his laboratory in previous experiments (later identified as "Roentgen rays" or "X-Rays"). His early experiments were with Crookes tubes, a cold cathode electrical discharge tube. Soon after, much of Tesla's early research—hundreds of invention models, plans, notes, laboratory data, tools, photographs, valued at $50,000—was lost in the 5th Avenue laboratory fire of March 1895. Tesla is quoted by The New York Times as saying, "I am in too much grief to talk. What can I say?" Tesla may have inadvertently captured an X-ray image—predating, by a few weeks, Wilhelm Röntgen's December 1895 announcement of the discovery of x-rays—when he tried to photograph Mark Twain illuminated by a Geissler tube, an earlier type of gas discharge tube. The only thing captured in the image was the metal locking screw on the camera lens.:134

Question: Who was Tesla trying to photograph when he accidentally took the X-Ray image?

On 23 June 2005, Rep. Joe Barton, chairman of the House Committee on Energy and Commerce wrote joint letters with Ed Whitfield, Chairman of the Subcommittee on Oversight and Investigations demanding full records on climate research, as well as personal information about their finances and careers, from Mann, Bradley and Hughes. Sherwood Boehlert, chairman of the House Science Committee, said this was a "misguided and illegitimate investigation" apparently aimed at intimidating scientists, and at his request the U.S. National Academy of Sciences arranged for its National Research Council to set up a special investigation. The National Research Council's report agreed that there were some statistical failings, but these had little effect on the graph, which was generally correct. In a 2006 letter to Nature, Mann, Bradley, and Hughes pointed out that their original article had said that "more widespread high-resolution data are needed before more confident conclusions can be reached" and that the uncertainties were "the point of the article".

Both B cells and T cells carry receptor molecules that recognize specific targets. T cells recognize a "non-self" target, such as a pathogen, only after antigens (small fragments of the pathogen) have been processed and presented in combination with a "self" receptor called a major histocompatibility complex (MHC) molecule. There are two major subtypes of T cells: the killer T cell and the helper T cell. In addition there are regulatory T cells which have a role in modulating immune response. Killer T cells only recognize antigens coupled to Class I MHC molecules, while helper T cells and regulatory T cells only recognize antigens coupled to Class II MHC molecules. These two mechanisms of antigen presentation reflect the different roles of the two types of T cell. A third, minor subtype are the γδ T cells that recognize intact antigens that are not bound to MHC receptors.

What class of T cells recognizes intact antigens that are not associated with MHC receptors?

Sir Charles Lyell first published his famous book, Principles of Geology, in 1830. This book, which influenced the thought of Charles Darwin, successfully promoted the doctrine of uniformitarianism. This theory states that slow geological processes have occurred throughout the Earth's history and are still occurring today. In contrast, catastrophism is the theory that Earth's features formed in single, catastrophic events and remained unchanged thereafter. Though Hutton believed in uniformitarianism, the idea was not widely accepted at the time.

Which famous evolutionist was influenced by the book Principles of Geology?
