Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Sir John a British scientist who won last year's Nobel prize for medicine, said he had predicted at the time of his frog experiments that the successful cloning of a mammal would happen within 50 years.and that "maybe the same answer is appropriate" far the step to human cloning. Parents who lose children in accidents may be able to clone "copies" to replace them then. Although any attempt to clone an entire human would raise complex moral issues, the biologist claimed people would soon overcome their concerns if the technique became medically useful.Cloning was regarded with extreme doubts when it was first developed but became widely accepted after the birth of Louise Brown, the first "test tube baby" He said, "When my first frog experiment.s were done, an American reporter asked how long it will be before these things can he done in mammals or humans I said, 'Well, it could be anywhere between 10 years and 100 years-how about 50 year ?' It turned out that it wasn't far off the mark as far as Dolly was concerned.Maybe the same answer is appropriate." Sir John added that cloning a human being effectively means making an identical twin, and doctors would therefore simply be "copying what nature has already produced" The average vote on allowing parents of deceased children, who are no longer fertile , to create another using the mother's eggs and skin cells from the first child, thinking the technique was safe and effective, is 60 per cent in favor.The reasons for "no" are usually that the new child would feel they were some sort of a replacement for something. . Options: A The life of Sir John, B Predict/on on human cloning. C Views on human cloning D Achievements in human cloning. Answer: B Predict/on on human cloning. Question:

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Poor Oral Health Leads to Social and Emotional Problems A new report says nearly four-billion people have major tooth decay, or cavities. That number represents more than half of the world's population. Health officials are warning that failure to repair cavities can lead to social and emotional problems. Wagner Marcenes is with the Institute of Dentistry at Queen Mary, University of London. He led a team of researchers as part of the Global Burden of Disease 2010 study. About 500 researchers attempt to collect and examine studies about all major diseases. They used the information to estimate rates of the infection. The report says untreated tooth decay is the most common of all 291 major diseases and injuries. Professor Marcenes says cavities or holes in permanent teeth are also known as caries. "Caries is a chronic disease that shares the same risk factors as cancer, cardiovascular disease. What we're having now is an increase in disease from highly developed countries happening in sub-Saharan Africa and probably it will be in other areas of Africa, too." He says an increase in tooth decay in Africa could be a result of developing countries becoming more like Western nations. "It is likely to be related to a change in diet. Our industrialized diet leads to chronic disease, which includes caries. And that may be the main explanation." Western diets are rich in sugar, a leading cause of health problems in the mouth. Wagner Marcenes says oral health problems can have a major effect on a person's quality of life. First, cavities make eating difficult. Second, people may change what they eat. They may eat softer foods that are not hard to chew. However, softer foods are often fattier foods. But professor Marcenes says the biggest issue in tooth decay is both social and mental. He says the researchers found strong evidence that the mouth has a big influence on socialization. He says many people want to hide bad teeth. They smile less and communicate less. Wagner Marcenes is calling for an "urgent, organized,... Options: A works as the leader of the Institute of Dentistry at Queen Mary, University of London. B and his researchers accumulate some studies to find out some ways to cure all major disease. C is in charge of the activity to estimate the infection rate with the collected and examined studies about all major studies. D thinks that the most serious problem caused by tooth decay is cancer that will last for a long time. Answer: C is in charge of the activity to estimate the infection rate with the collected and examined studies about all major studies. Question:???
output answer: From the passage, we know that Wagner Marcenes _ .

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: When TV news programmers report wars or diseases, the editors rarely use the most horrifying pictures of dead or wounded victims because they don't want to upset their viewers. Even so, viewers are usually warned in advance that they"may find some of these scenes disturbing", so they can look away if they choose. But the men and women whose job is to record those scenes, the TV cameramen, have no such choice. It is their duty to witness the horrors of the world and record them, no matter how unpleasant they may be. As a result, it is one of the most dangerous, exposed and emotionally _ jobs the world has to offer. Today, the demand for their work is rising. The explosion of satellite broadcasting and 24hour news in recent years has created an almost insatiable demand for TV information. But major broadcaster sand the TV news agencies , such as Reuters and WTN, have never had enough staff to meet thje worldwide demand for up-to-date pictures, so increasingly they turn to freelance TV cameramen. These freelance cameramen are independent operators tied to no particular organization. They will work for any company which hires them, for just a few hours or for several weeks in a war zone. But if the freelance cameraman is injured in the course of the job, the TV company is not responsible for him. The freelance must survive on his own. "TV will always need hard, vivid and moving pictures which are fresh, but these companies feel uncomfortable with large numbers of employees on their books."Explains Nik Cowing, once a foreign editor for Britain's Channel 4 news and now a BBC news presenter. "By hiring freelancers, they can buy in the skills they need only when they need them. It also enables them to reduce the risk."He says.
