input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Air pollution is one of the hottest topics at present because poor air quality is an important factor in both the incidence and cause of respiratory diseases. Zhong Nanshan, a deputy to the NPC and a member of the CAE, said recently when the concentration of PM2.5 rises by 10 micrograms per cubic meter, hospitalization may rise by as much as 3.1 percent. Meanwhile, when the concentration of PM2.5 rises from 25 mgs per cubic meter to 200, the average daily death rate may rise to 11 percent. Zhi Xiuyi, a leading expert in lung cancer treatment and also vice-president of the CATS, said medical authorities used to focus on tobacco control as a primary means of preventing lung cancer. "But in fact, air pollution is no less harmful than smoking and our research team released a report earlier this year showing that the cancer rate in Beijing is closely related to industrialization," he said. The report, conducted by the Beijing Institute of Cancer Research, shows that the number of cancer patients in China has increased markedly during the past ten years. Chaoyang District, the city's main area of industrialization, has the highest incidence of cancer, almost double that of Yanqing, an area on the outskirts of the city. About four out of 1000 Chaoyang residents have some form of the disease, with lung cancer at the top of the list. "The risk of having cancer largely depends on the length of exposure and the concentration of noxious gases ," said Zhi. In response to the doubt whether seven years' exposure to poor air quality will almost result in cancer, Zhi said the time scale was taken from research overseas that suggested the rate of incidence generally peaked in the seventh year of exposure to a heavily polluted environment. Options: A 16000 B 12000 C 8000 D 7500 Answer: B 12000 Question:???
output answer: If there were 3,000,000 people in Chaoyang District, how many would have respiratory diseases?

Write a multi-choice question for the following article, with the given choices and answer: Article: A serious problem for today's society is who should be responsible for our elderly and how to improve their lives. It is not only a financial problem but also a question of the system we want for our society. I would like to suggest several possible solutions to this problem. First, employers should take the responsibility for their retired employees. To make this possible, a percentage of profits should be set aside for this purpose. But when a company must take life-long responsibility for its employees, it may suffer from a commercial disadvantage due to higher employee costs. Another way of solving the problem is to return the responsibility to the individual. This means each person must save during his working years to pay for his years of retirement. This does not seem a very fair model since some people have enough trouble paying for their daily life without trying to earn extra to cover their retirement years. This means the government might have to step in to care for the poor. In addition, the government could take responsibility for the care of the elderly. This could be financed through government taxes to increase the level of pensions. Furthermore, some institutions should be created for senior citizens, which can help provide a comfortable life for them. Unfortunately, as the present situation in our country shows, this is not a truly _ answer. The government can seldom afford to care for the elderly, particularly when it is busy trying to care for the young. One further solution is that the government or social organizations establish some working places especially for the elderly where they are independent. To sum up, all these options have advantages and disadvantages. Therefore, it is reasonable to expect that some combination of these options may be needed to provide the care we hope to give to our elderly generations. Options: A The problems faced by the old in society. B Why we should take responsibility for the old. C How we can improve the lives of the old. D Where the old can go to get their pensions. Answer: C How we can improve the lives of the old. Question:

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Looking for a new weight loss plan? Try living on the top of a mountain.Mountain air contains less oxygen than air at lower altitudes,so breathing it causes the heart to beat faster and the body to burn more energy. Studies have found that athletes training at high altitudes tend to lose weight.Doctor Florian Lippl in Germany wondered how the mountain air would affect _ individuals if they weren't doing any more physical activity than usual. Lippl and his colleagues invited 20 obese men to an environmental research station about 300 meters below the summit of Zugspitze, mountain around 2, meters near the Austrian border.2,970 This was no hiking expedition. They were allowed to eat as much as they liked. men also gave The blood so that researchers could test for hormones linked to appetite and obesity.At the end of the week, men, the whose weight starting out was 105 kilograms, had lost about 1.5 kg on average.The men's blood pressure also dropped,which the researchers owed to weight lost. Exactly what caused the weight loss is uncertain.Loss of appetite is common at higher altitudes, and indeed the men ate significantly less than usua!--about 700 calories fewer per day. Appetite loss at high altitudes could certainly be key,notes Damian Bailey,a physiologist, who himself recently lost 11 kg during a 3-month expedition to the Andes in Chile. Unfortunately,for the average person there's no treatment that can resemble living at high altitudes, says Lippl.He says,half-jokingly, obese people plan their holidays,they might not "If go to the sea,but maybe to the mountains." Options: A They controlled what to eat. B They took in fewer calories than usual. C They lost appetite because of lack of physical activities. D They were provided with a healthier diet than before. Answer: B They took in fewer calories than usual. Question:
A: What was found about the 20 obese men in the process of the research?
