input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Let's face it.No one drinks die t soda for the taste.People drink diet soda in the hope that it will help them lose weight or at least keep them from gaining it.Yet it seems to have exactly the opposite effect, according to a new study. Researchers from the University of Texas said those who drank two or more diet sodas a day had waist size increases that were six times greater than those of people who didn't drink diet soda."What we saw was that the more diet sodas a person drank, the more weight they were likely to gain," said Sharon Fowler. The study was based on data from 474 participants in a large, ongoing research project, where the participants were followed for nearly l0 years. While the findings are surprising, they also offer some explanations. Nutrition expert, Melanie Rogers, who works with overweight patients in New York, has found that when patients are switched from regular to diet soda, they don't lose weight at all."We weren't seeing weight loss necessarily, and that was confusing to us," said Rogers. So why would diet soda cause weight gain? No one knows for sure yet, but it could be that people think they can eat more if they drink diet soda, and so over-compensate for the missing calories( ). A related study found some sweeteners raised blood sugar levels in some mice." Data from this and other potential studies suggest that the promotion of diet sodas and artificial sweeteners may be risky," said study researcher Helen P.Hazuda, professor at the University of Texas's school of medicine. Theymay be free of calories, but not of consequences. Options: A diet soda drinkers tend to eat more food B regular soda makes people lose more weight C most blood diseases come from diet soda D diet soda does help reduce calories Answer: A diet soda drinkers tend to eat more food Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Protecting Copyright Having finished her homework, Ma Li wants some music. As usual, she starts her computer and goes to Baidu.com to download music files. But this time she is surprised when an announcement about protecting songs' copyright bursts onto the screen. The age of free music and movie downloads may have come to an end as Web companies like Baidu are accused of pirating copyright. Lawsuits have been filed against four websites offering free downloads. In September 2005, a Beijing court ordered Baidu to pay recording company Shanghai Push compensation for their losses. Baidu was also told to block the links to the pirated music on the website. This caused a heated discussion on Interact file sharing. "Baidu's defeat in the lawsuit shows it is not right to get copyrighted songs without paying. Down loaders may face lawsuits or fines," said an official. Like many teens, Huang Ruoru, an 18-year-old girl from Puning in Guangdong Province, doesn't think that getting music from websites is wrong. She always shares her favourite songs downloaded from Baidu with her friends. When told about the lawsuit, she began to feel a little guilty about obtaining others' work without paying. However, other teenagers have different ideas. Wang Yafei, a Senior 2 girl from Jinan, Shandong Province pointed out that file sharing is a good way to promote pop singers. "If I download a song and really like it, I will buy the CD," she said. "So what the recording companies really should concentrate on is improving their music, rather than file-sharers." Options: A Web companies are still ignoring the copyright laws. B Teenagers haven't got money to buy CDs. C Teenagers are probably still downloading free music. D Teenagers prefer CDs with copyright to pirated music. Answer: C Teenagers are probably still downloading free music. Question:

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Life on earth depends on water, and there is no substitute for it. The current assumption is that our basic needs for water--whether for drinking, agriculture, industry or the raising of fish--will always have to be met. Given this premise , there are two basic routes we can go; more equal access to water or better engineering solutions. Look at the engineering solutions first. A lot of my research concentrates on what happens to wetlands when you build dams in river basins, particularly in Africa. The ecology of such areas is almost entirely driven by the seasonal changes of the river--the pulse of the water. And the fact is that if you build a dam, you generally spoil the downstream ecology. In the past, such problems have been hidden by a lack of information. But in the near future, governments will have no excuses for their ignorance. The engineers' ability to control water flows has created new kinds of unpredictability, too. Dams in Africa have meant fewer fish, less grazing and less floodplain agriculture, none of which were expected. And there average economic life is assumed to be thirty years. Dams don't exist forever, but what will replace them is not clear. The challenge for the future is to find new means of controlling water. Although GM technology will allow us to breed better dry-land crops, there is no market for companies to develop crops suitable for the micro-climates of the Sahel and elsewhere in Africa. Who is going to pay for research on locally appropriate crops in the Third World? Options: A The engineering solutions to water resource and their limitation. B The challenge for the future. C The basic means of controlling water. D The challenge for developing crops. Answer: A The engineering solutions to water resource and their limitation. Question:

A: What's the main idea of this passage?

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: A few years ago it was popular to speak of a generation gap, a disagreement between young people and their elders.Parents said that children did not show them proper respect and obedience , while children complained that their parents did not understand them at all.What had gone wrong? Why had the generation gap suddenly appeared? Actually the generation gap has been _ for a long time.Many people argue that a gap is built into the fabric of our society. One important cause of the generation gap is the chance that young people have to choose their own ways of life.In more traditional societies, when children grow up, they are expected to live in the same area as their parents, to marry people that their parents know and agree to, and to continue the family occupation .In our society, young people often travel great distances for their education, move out of the family home at an early age, marry or live with people whom their parents have never met, and choose occupations different from those of their parents. In our easily changing society, parents often expect their children to do better than they did: to find better jobs, to make more money, and to do all the things that they were unable to do.Often, however, the strong desire that parents have for their children are another cause of the disagreement between them.Often, they discover that they have very little in common with each other. Finally, the speed at which changes take place in our society is another cause of the gap between the generations.In a traditional culture, elderly people are valued for their wisdom, but in our society the knowledge of a lifetime may become out of date overnight.The young and the old seem to live in two very different worlds, separated by different skills and abilities. No doubt, the generation gap will continue to be a feature of American life for some time to come.Its causes are rooted in the freedom and changes of our society, and in the rapid speed at which society changes. Options: A Parents should be strict with their children. B The younger generation should value the older generation for their wisdom. C The generation gap is partly caused by the older generation. D The generation gap does not exist in American society. Answer: C The generation gap is partly caused by the older generation. Question:???
