Boeing will temporarily halt production of its troubled 737 Max airliner in January, the manufacturer said. Production of the jet had continued despite the model being grounded for nine months after two deadly crashes. More than 300 people died when two 737 Max aircraft crashed in Indonesia and Ethiopia after reported problems with a new feature. Boeing had been hoping to have the planes back in the air by the end of this year. But US regulators made it clear that they would not be certified to return to the skies that quickly. What will Boeing do next? Boeing is one of the largest US exporters. The company said in a statement that it would not lay off workers associated with the 737 Max, but the stoppage is likely to affect suppliers and the wider economy. "Safely returning the 737 Max to service is our top priority," the aircraft manufacturer said. "We know that the process of approving the 737 Max's return to service, and of determining appropriate training requirements, must be extraordinarily thorough and robust, to ensure that our regulators, customers, and the flying public have confidence in the 737 Max updates." What went wrong with the planes? Last week a congressional hearing was told that US aviation regulators were aware, following the first crash in Indonesia in October 2018, that there was a risk of further accidents. The Federal Aviation Authority's analysis suggested there could be more than a dozen more crashes over the lifetime of the aircraft unless changes were made to its design. Despite that, the 737 Max was not grounded until after the second crash in Ethiopia in March 2019. Boeing is redesigning the automated control system thought to have been the primary cause of the crashes. The manufacturer said it had 400 of the 737 Max aircraft in storage and would focus on delivering those to customers. While many airlines around the world have the planes on order, delivery was halted to allow Boeing's engineers to develop software fixes. The situation surrounding the 737 Max is extraordinary. Nine months after the aircraft was grounded worldwide, it is still not clear when it will be certified to fly again. Regulators - criticised for allowing a flawed aircraft to fly in the first place - are now playing hardball. For Boeing, being forced to shut down the production line is deeply embarrassing - and likely to prove costly. But it is a huge business, and it can at least redeploy many of its workers. But if the stoppage goes on for long, suppliers could be badly hit. Boeing sits at the top of a global supply chain, ranging from major businesses to small operators. Here in the UK, for example, the company works across 65 sites, including a factory in Sheffield. But it draws on a network of some 300 suppliers. For smaller firms in particular, losing 737-related work could prove serious - hitting revenues and potentially forcing them to lay off workers as well. What has the reaction been? Travel industry analyst Henry Harteveldt said the decision to suspend production was unprecedented and likely to have a "massive impact on Boeing, its suppliers and the airlines". "It's really going to create some chaos for the airlines that are involved in this as well as the 600 or so companies that are part of the 737 Max supply chain and Boeing itself." The suspension of the 737 Max has already cost Boeing around $9bn (£6.75bn). Boeing shares fell more than 4% on Monday amid speculation production would be suspended. The production freeze is expected to be felt across the plane's global supply chain. Teal Group aviation analyst Richard Aboulafia described Boeing's options for managing the blow to its suppliers as "bad and worse". He said the plane maker could either allow them to take a hit, or pay them to wait for when the 737 Max is finally cleared to fly. US carriers operate the largest 737 Max fleets, though airlines around the world also use it. "The Chinese carriers would [also] be quite badly affected. They're some of the biggest users of the Max," said Shukor Yusof, aviation analyst at Endau Analytics. In fact, China's three largest carriers were among the first to press Boeing for compensation over the grounded planes. Aviation analyst Chris Tarry told the Today programme: "The last thing any manufacturer wants is to stop the production line and it's going to take time to get it going again when the aircraft takes to the skies. "If we look at it in terms of the volume of the impact on capacity growth in the industry, it is significant and it will take time to recover the production. Boeing's reputation will take time to recover from this as well." How are other businesses affected? Some suppliers, such as fuselage maker Spirit AeroSystems, are highly dependent on the jet, with half of its revenue attached to it, according to Mr Aboulafia. So far, the supplier has only said it is "working closely" with Boeing to determine what impact the production suspension may have. The move by Boeing is unlikely to affect passengers as airlines have leased additional aircraft to replace the 737 Max. It's a different story for airlines, who have the added expense of leasing planes and managing their grounded aircraft. In July, Boeing set aside nearly $5bn to compensate those affected. However, that figure assumed that the 737 Max would fly again this year.

Camille Jouvenceau has an amazing view of Western Europe's highest mountain, Mont Blanc, from the balcony of her apartment in the pretty town of Sallanches. But the mountain air does not entice her. By John LaurensonBBC News, Sallanches, France "The air stinks outside, so you think twice about going out," she says. She has had bronchitis, asthma and ear infections on and off since the end of November, when the fine particle pollution started peaking at red alert levels. "Before you leave the house you ask yourself whether the air's going to make you cough or make your eyes stream or you have to spit," says Ms Jouvenceau, 24. "I leave earlier now when I go to work, so that I can walk slowly and of course I've stopped cycling or doing any sport." It's like this every year in the 105km-long (65-mile) Arve Valley, home to 150,000 people and surrounded by some of the world's most famous ski resorts - Megeve, Saint Gervais and Chamonix. Seasonal scourge The pollution from fine (PM10) and ultra-fine (PM2.5) particles - the ones that get right down into your bronchial tubes and do the most damage - is now dangerously high for an average of 40 days a year. In winter, this part of the Alps has the worst fine-particle pollution in France. The problem is compounded by the fact that, at the bottom of these deep mountain valleys, the air is often cooler than higher up. Since it is cooler, the air does not rise or disperse easily. Prof Frank Kelly, chair of environmental health at King's College, London, says the mountains also block the wind, "rather like the mountains north of Beijing, which stop the dispersal of the wind-borne pollution from the south". He has been working with the French on a monitoring project in the Arve Valley. At St Joseph's Infant and Primary School, the youngest children are kept inside at break time, while the older ones are allowed into the playground, but are not allowed to run around. "Since the pollution alert started, the authorities have stopped all school sport," says head teacher Nathalie Gex. "No skating, no swimming pool even. Our gym teacher's been giving theatre classes instead. At break time we give the older children chalk to draw on the ground, and cards and building blocks to play with, to make sure they don't move too much." Wood-burning tradition It's a beautiful day and I climb up above Sallanches - by car of course, I'm not going hiking in this air. I was told you can see the pollution from up here. Well, you absolutely can. There is a thick, white quilt of it lying across the town. The other thing you can see from up the mountain is the main cause. Surprisingly, perhaps, it is not the lorries grinding up the valley towards the Mont Blanc Tunnel and Italy. No, the main cause is a renewable energy source with an environmentally-friendly reputation - the humble wood-burning stove. Columns of smoke are rising from many of the houses. "The latest surveys show that between 60% and 80% of fine-particle pollution here comes from wood-burning stoves and fireplaces in people's homes," says Vincent Hazout, who recently organised a demonstration calling for action against air pollution. It rallied 1,000 people in Sallanches. Mr Hazout's six-year-old son is currently ill with asthma. When he was his son's age, he suffered from asthma too. His family lived in Paris but took the decision to leave because of young Vincent's health. They came to Alps for the "clean mountain air". "Now we'll have to move too for my son, like my parents moved for me, unless we can solve this pollution problem," Mr Hazout says. Clean-up campaign The power to do something about the air in this valley lies mainly with the representative of central government, called the prefect. His office, though declining an interview, provided details of all the anti-air pollution measures taken this winter - and there are quite a few of them: restrictions on the most-polluting heavy goods vehicles, a voluntary slow-down of some industrial activity, a decrease in volume of refuse-burning and a ban on burning wood for households with alternative means of heating. "Clearly insufficient," says Mr Hazout. "The authorities don't want to implement more drastic measures, for fear of blackening the image of the ski resorts." So how are things up on the pistes? In Chamonix, which attracts thousands of skiers each year, Mayor Eric Fournier says that on the slopes you are fine as you are above the danger zone, and that even in the town the pollution is not nearly as bad as it is down in the valley. He also says air quality is actually improving in Chamonix, because of an upgrade scheme for wood-burning stoves, which he has put in place. But the air quality in Chamonix on winter evenings is still poor. Plenty of wood smoke continues to pump fine particles into the air, despite this scheme.

# Output (b):
The government has taken a number of anti-air pollution measures during the winter, including restrictions on heavy goods vehicles, a voluntary slow-down of some industrial activity, a decrease in volume of refuse-burning, and a ban on burning wood for households with alternative means of heating. Residents of the Arve Valley are not satisfied with these measures, as they believe more drastic measures are needed to solve the pollution problem. They are calling for more financially attractive or mandatory measures to change the way people heat their homes.

# Output (a):
The French government has taken several anti-air pollution measures during the winter in the Arve Valley, including restrictions on heavy goods vehicles, a voluntary slow-down of some industrial activity, a decrease in refuse-burning, and a ban on burning wood for households with alternative heating. However, residents believe these measures are insufficient and want more drastic action taken against the main cause of pollution - wood-burning stoves and fireplaces in people's homes. Vincent Hazout, who recently organised a demonstration calling for action against air pollution, believes changing the way people heat their homes should become mandatory or more financially attractive.

Camille Jouvenceau has an amazing view of Western Europe's highest mountain, Mont Blanc, from the balcony of her apartment in the pretty town of Sallanches. But the mountain air does not entice her. By John LaurensonBBC News, Sallanches, France "The air stinks outside, so you think twice about going out," she says. She has had bronchitis, asthma and ear infections on and off since the end of November, when the fine particle pollution started peaking at red alert levels. "Before you leave the house you ask yourself whether the air's going to make you cough or make your eyes stream or you have to spit," says Ms Jouvenceau, 24. "I leave earlier now when I go to work, so that I can walk slowly and of course I've stopped cycling or doing any sport." It's like this every year in the 105km-long (65-mile) Arve Valley, home to 150,000 people and surrounded by some of the world's most famous ski resorts - Megeve, Saint Gervais and Chamonix. Seasonal scourge The pollution from fine (PM10) and ultra-fine (PM2.5) particles - the ones that get right down into your bronchial tubes and do the most damage - is now dangerously high for an average of 40 days a year. In winter, this part of the Alps has the worst fine-particle pollution in France. The problem is compounded by the fact that, at the bottom of these deep mountain valleys, the air is often cooler than higher up. Since it is cooler, the air does not rise or disperse easily. Prof Frank Kelly, chair of environmental health at King's College, London, says the mountains also block the wind, "rather like the mountains north of Beijing, which stop the dispersal of the wind-borne pollution from the south". He has been working with the French on a monitoring project in the Arve Valley. At St Joseph's Infant and Primary School, the youngest children are kept inside at break time, while the older ones are allowed into the playground, but are not allowed to run around. "Since the pollution alert started, the authorities have stopped all school sport," says head teacher Nathalie Gex. "No skating, no swimming pool even. Our gym teacher's been giving theatre classes instead. At break time we give the older children chalk to draw on the ground, and cards and building blocks to play with, to make sure they don't move too much." Wood-burning tradition It's a beautiful day and I climb up above Sallanches - by car of course, I'm not going hiking in this air. I was told you can see the pollution from up here. Well, you absolutely can. There is a thick, white quilt of it lying across the town. The other thing you can see from up the mountain is the main cause. Surprisingly, perhaps, it is not the lorries grinding up the valley towards the Mont Blanc Tunnel and Italy. No, the main cause is a renewable energy source with an environmentally-friendly reputation - the humble wood-burning stove. Columns of smoke are rising from many of the houses. "The latest surveys show that between 60% and 80% of fine-particle pollution here comes from wood-burning stoves and fireplaces in people's homes," says Vincent Hazout, who recently organised a demonstration calling for action against air pollution. It rallied 1,000 people in Sallanches. Mr Hazout's six-year-old son is currently ill with asthma. When he was his son's age, he suffered from asthma too. His family lived in Paris but took the decision to leave because of young Vincent's health. They came to Alps for the "clean mountain air". "Now we'll have to move too for my son, like my parents moved for me, unless we can solve this pollution problem," Mr Hazout says. Clean-up campaign The power to do something about the air in this valley lies mainly with the representative of central government, called the prefect. His office, though declining an interview, provided details of all the anti-air pollution measures taken this winter - and there are quite a few of them: restrictions on the most-polluting heavy goods vehicles, a voluntary slow-down of some industrial activity, a decrease in volume of refuse-burning and a ban on burning wood for households with alternative means of heating. "Clearly insufficient," says Mr Hazout. "The authorities don't want to implement more drastic measures, for fear of blackening the image of the ski resorts." So how are things up on the pistes? In Chamonix, which attracts thousands of skiers each year, Mayor Eric Fournier says that on the slopes you are fine as you are above the danger zone, and that even in the town the pollution is not nearly as bad as it is down in the valley. He also says air quality is actually improving in Chamonix, because of an upgrade scheme for wood-burning stoves, which he has put in place. But the air quality in Chamonix on winter evenings is still poor. Plenty of wood smoke continues to pump fine particles into the air, despite this scheme. For Vincent Hazout, the way forward is obvious. But it will take political will. Changing the way people heat their homes would have to become far more financially attractive or, if that failed, mandatory. Prof Kelly agrees.

At St Joseph's Infant and Primary School, the youngest children are kept inside at break time, while the older ones are allowed into the playground, but are not allowed to run around. "Since the pollution alert started, the authorities have stopped all school sport," says head teacher Nathalie Gex. "No skating, no swimming pool even. Our gym teacher's been giving theatre classes instead. At break time we give the older children chalk to draw on the ground, and cards and building blocks to play with, to make sure they don't move too much." Wood-burning tradition It's a beautiful day and I climb up above Sallanches - by car of course, I'm not going hiking in this air. I was told you can see the pollution from up here. Well, you absolutely can. There is a thick, white quilt of it lying across the town. The other thing you can see from up the mountain is the main cause. Surprisingly, perhaps, it is not the lorries grinding up the valley towards the Mont Blanc Tunnel and Italy. No, the main cause is a renewable energy source with an environmentally-friendly reputation - the humble wood-burning stove. Columns of smoke are rising from many of the houses. "The latest surveys show that between 60% and 80% of fine-particle pollution here comes from wood-burning stoves and fireplaces in people's homes," says Vincent Hazout, who recently organised a demonstration calling for action against air pollution. It rallied 1,000 people in Sallanches. Mr Hazout's six-year-old son is currently ill with asthma. When he was his son's age, he suffered from asthma too. His family lived in Paris but took the decision to leave because of young Vincent's health. They came to Alps for the "clean mountain air". "Now we'll have to move too for my son, like my parents moved for me, unless we can solve this pollution problem," Mr Hazout says. Clean-up campaign The power to do something about the air in this valley lies mainly with the representative of central government, called the prefect. His office, though declining an interview, provided details of all the anti-air pollution measures taken this winter - and there are quite a few of them: restrictions on the most-polluting heavy goods vehicles, a voluntary slow-down of some industrial activity, a decrease in volume of refuse-burning and a ban on burning wood for households with alternative means of heating. "Clearly insufficient," says Mr Hazout. "The authorities don't want to implement more drastic measures, for fear of blackening the image of the ski resorts." So how are things up on the pistes? In Chamonix, which attracts thousands of skiers each year, Mayor Eric Fournier says that on the slopes you are fine as you are above the danger zone, and that even in the town the pollution is not nearly as bad as it is down in the valley. He also says air quality is actually improving in Chamonix, because of an upgrade scheme for wood-burning stoves, which he has put in place. But the air quality in Chamonix on winter evenings is still poor. Plenty of wood smoke continues to pump fine particles into the air, despite this scheme. For Vincent Hazout, the way forward is obvious. But it will take political will. Changing the way people heat their homes would have to become far more financially attractive or, if that failed, mandatory. Prof Kelly agrees. "This pollution has three causes: the topography, the climate and the use of wood as heating fuel. We can't change the first two - although the Chinese have been experimenting with making rain to wash away pollution - but we can act on the wood-burning," he says. In January 2015, the authorities in the Paris region banned the use of open fireplaces (more polluting than closed ones), before Ecology Minister Segolene Royal intervened to lift the order. Many people in the French Alps hope that that measure, or an even more comprehensive ban on wood-heating, will be applied here. "In two years," says Mr Hazout, "we could have this problem solved".

Here is a summary requirement:
Summarize the health issues faced by Camille Jouvenceau due to air pollution.

Please summarize the above article based on the given requirement:

Camille Jouvenceau, a resident of Sallanches, France, has been suffering from bronchitis, asthma, and ear infections since the end of November due to the fine particle pollution in the air. She has to think twice before going out as the air stinks outside. The pollution from fine and ultra-fine particles is dangerously high for an average of 40 days a year in the Arve Valley, where she lives. The pollution is caused mainly by wood-burning stoves and fireplaces in people's homes. The authorities have taken some anti-air pollution measures, but they are considered insufficient by the residents.

Camille Jouvenceau has bronchitis, asthma and ear infections as a result of air pollution. She has to be careful about going outside, and has to take precautions when she does. School sports have been cancelled, and children are kept inside at break times. The main cause of the pollution is wood-burning stoves. Vincent Hazout, who organised a demonstration against air pollution, says that more drastic measures are needed to solve the problem.


You are a helpful assistant in evaluating the quality of the outputs for a given instruction. Your goal is to select the best output for the given instruction.

Select the Output (a) or Output (b) that is better for the given instruction. The two outputs are generated by two different AI chatbots respectively.

Here are some rules of the evaluation:
(1) You should prioritize evaluating whether the output honestly/precisely/closely executes the instruction, then consider its helpfulness, accuracy, level of detail, harmlessness, etc.
(2) Outputs should NOT contain more/less than what the instruction asks for, as such outputs do NOT precisely execute the instruction.
(3) You should avoid any potential bias and your judgment should be as objective as possible. For example, the order in which the outputs were presented should NOT affect your judgment, as Output (a) and Output (b) are **equally likely** to be the better.

Do NOT provide any explanation for your choice.
Do NOT say both / neither are good.
You should answer using ONLY "Output (a)" or "Output (b)". Do NOT output any other words.

Camille Jouvenceau has an amazing view of Western Europe's highest mountain, Mont Blanc, from the balcony of her apartment in the pretty town of Sallanches. But the mountain air does not entice her. By John LaurensonBBC News, Sallanches, France "The air stinks outside, so you think twice about going out," she says. She has had bronchitis, asthma and ear infections on and off since the end of November, when the fine particle pollution started peaking at red alert levels. "Before you leave the house you ask yourself whether the air's going to make you cough or make your eyes stream or you have to spit," says Ms Jouvenceau, 24. "I leave earlier now when I go to work, so that I can walk slowly and of course I've stopped cycling or doing any sport." It's like this every year in the 105km-long (65-mile) Arve Valley, home to 150,000 people and surrounded by some of the world's most famous ski resorts - Megeve, Saint Gervais and Chamonix. Seasonal scourge The pollution from fine (PM10) and ultra-fine (PM2.5) particles - the ones that get right down into your bronchial tubes and do the most damage - is now dangerously high for an average of 40 days a year. In winter, this part of the Alps has the worst fine-particle pollution in France. The problem is compounded by the fact that, at the bottom of these deep mountain valleys, the air is often cooler than higher up. Since it is cooler, the air does not rise or disperse easily. Prof Frank Kelly, chair of environmental health at King's College, London, says the mountains also block the wind, "rather like the mountains north of Beijing, which stop the dispersal of the wind-borne pollution from the south".
