Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Dogs have long been used to find explosives and drugs.Now,a new study shows that man's best friend can also help to find lung and breast cancer,researchers report in integrative Cancer Therapies.The findings show that trained ordinary household dogs can detect early--stage lung and breast cancers by smelling the breath samples of patients. Researchers have found that cancer cells send out molecules different from those of healthy ones,and that might be sensed by smell by the highly sensitive dog's nose. For the study,five dogs were trained by a professional instructor to respond differently to breath samples of healthy and cancer patients."The dogs learned to sit or lie down in front of cancer patient samples and to ignore control samples through the method of food reward," McCulloch explained. After a period of training,researchers tested the animals'ability to distinguish cancer patients from controls.The animals were given breath samples from 55 patients with lung cancer,3 1 with breast cancer and 83 healthy controls who were not included in the original training period. McCulloch's group found that the dogs were able to correctly distinguish the breath samples of cancer patients from those of the control subjects in about 90 percent of the cases.The dogs were also able to detecting early-stage lung and breast cancers. "These results show that there is hope for early detection,"McCulloch said.The re-searches are planning to conduct further studies on the breath composition of cancer patients to possibly design an electronic device that can do the dogs'job."A dog's nose is so powerful it can detect odors 10 000 to 100 000 times better than a human nose can.I hope people will be interested in doing this research,"McCulloch added,"It shows that there is definitely something out there." Options: A dogs can smell signs of other cancers except the above two kinds B the final goal of the researchers is to design an electronic dog to detect cancer C dogs can detect odors 10 000 to 100 000 times better than humans can D dogs will soon be widely used to smell signs of cancers in hospitals Answer: B the final goal of the researchers is to design an electronic dog to detect cancer Question:
A: We can infer from the passage that_.

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Why doesn't the unemployment rate ever reach zero? Economists, who generally believe that supply tends to meet demand, have long thought about this question. Even in good times, i.e. not now, there are people who can't find work. And even in bad times, i.e. now, there are job openings. With over 14 million people out of work and looking for a job, you would think every available job would be filled. But that's not the case. Not now and not ever. On Monday, the Nobel Prize committee awarded the prize for economics to the three scholars who have done the most to explain this phenomenon. Two of the winners are Americans, Peter Diamond of MIT and Dale Mortensen of Northwestern. The third winner is Christopher Pissarides, who teaches at the London School of Economics and was born on Cyprus. Like most of economics, what they have found about why the jobless and ready-employers don't find each other seems obvious. You have to find out there is job opening you are interested in. Employers need to get resumes . It takes a while for both employers and employees to make the decision that this is what they want. And these guys came up with a frame-work to study the problem of why people stay unemployed longer than they should and what can be done about it. So what would today's Nobel Prize winners do to solve the current problem of the unemployed? And does the awarding of the prize contribute to the politicians' lowering joblessness? Speaking from his north London home, Pissarides told The Associated Press the announcement came as "a complete surprise" though his work had already helped shape thinking on both sides of the Atlantic. For example, the New Deal for Young People, a British government policy aimed at getting 18-24-year-olds back on the job market after long periods of unemployment, "is very much based on our work," he said. "One of the key things we found is that it is important to make sure that people do not stay unemployed too long so they don't lose their feel for the labor force," Pissarides told... Options: A Pissarides thinks his work surprising. B The work of Pissarides has influenced many economists. C Some of the winners' ideas have been put into practice. D It is probable that unemployed young people in Britain benefit from Pissarides' work. Answer: A Pissarides thinks his work surprising. Question:

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Man has always wanted to fly. Some of the greatest men in history have thought about the problem. One of these, for example, was the great Italian artist, Leonardo da Vinci. In the sixteenth century he made designs for machines that could fly. But they were never built., Throughout history, other less famous men have wanted to fly. An example was a man in England 800years ago. He made a pair of wings from chicken feathers. Then he fixed them to his body and jumped into the air from a tall building. He did not fly very far. He fell to the ground and broke every bone in his body. The first real step took place in France in 1783. Two brothers, the Mongolfiers, made a very large "hot air balloon". They knew that hot air rises. Why not fill a balloon with it? The balloon was made of cloth and paper. In September of that year, the King and Queen of France came to see the balloon. They watched it carry the very first air passengers into the sky. The passengers were a sheep and a chicken. We do not know how they felt about the trip. But we do know that the trip lasted 8 minutes and that the animals landed safely. Two months later, two men did the same thing. They rose above Paris in a balloon of the same kind. Their trip lasted twenty-five minutes and they traveled about 8 kilometers. Options: A lost his life B flew only 8 minutes C was not wounded D succeeded in flying Answer: A lost his life Question:
Answer:
In fact, the Englishman who tried to fly _ .
