Please answer this: Write a multi-choice question for the following article: Article: Sometimes successful health campaigns can have quite unexpected reactions. The years of warnings about skin cancer mean that Britons are happy to cover themselves in sunscreen or stay out of the sun altogether, but it also means that most of us are not getting enough vitamin D. Scientists announced yesterday that Britons need to increase to three times the amount of vitamin D they get per day. They called on food producers to fortify their products with more of the vitamin and suggested people should consider taking supplements to keep levels up. They also suggested getting out in the sun for short periods more often, but they warned against "sun bingeing". The government does not publish official advice on the amount of vitamin D people should take due to a lack of research, says Dr Birgit Teucher of the Institute for Food Research. But in the US, the government recommends 5 micrograms a day. By that count, Dr Birgit Teucher said that around 90% of Britons between 19 and 64 would be lacking in the vitamin because they only took around 3 micrograms a day. Vitamin D is important for absorption of calcium by the body, which is needed for healthy teeth and bones. A lack of it can lead to serious diseases in both children and adults. The vitamin can be found in some foods but it can also be obtained from chemicals in the skin reacting to sunlight. Dr Barbara Boucher said adults should get 5 to 25 micrograms a day. Shortage of vitamin D may be linked to diseases such as muscle weakness, high blood pressure and rickets . Dr Birgit Teucher gave several reasons for the lack among Britons. Increasing numbers of office-based jobs mean a lack of exposure to the sun; and the rise of becoming overweight means that vitamin D--which is fat soluble is increasingly stored in body fat, where it cannot be accessed readily. Professor Brian Wharton of the Institute of Child Health said that children in particular needed to have enough vitamin D to prevent rickets. Professor Graham Bentham, an environmental scientist at the...

Problem: Write a multi-choice question for the following article: Article: This July, Wang Chen, a student from Shanghai University of Finance and Economics, won the International University WEICHI Tournament 2013 in Shanghai, which saw competitors from 54 universities around the world, including Harvard University and Massachusetts Institute of Technology. Compared with the busy sports ground, it seems a bit dull, but Wang and his peers enjoy an intense brain workout . Wang is an amateur seventh-degree master player -- the highest degree amateur players can attain. "I had hoped to win first place, but when it came true, I couldn't believe it," says Wang. Wang began studying weichi when he was 7 years old. "I was a quiet boy and my parents thought weichi would help develop my logical thinking ability," he says. He began to attend the Chinese Rank Promotion from the age of 10. "I failed for nine years, and them I gave up. I entered university and became an amateur player," says Wang. What this hobby brings Wang is not only a sense of achievement, but also independence. He has won 10 national and international championships, which have brought the young student a handsome sum of money. When he won the national amateur competition in 2011, he received 100,000 yuan in prize money. With awards from contests, Wang covers his expenses and tuition fees all by himself. Wang is busier than most of his peers. A look at his calendar shows that he will attend competitions in Guizhou and Taiwan at the end of August, after attending an international competition only this July. But Wang admits he has little in common with his classmates. "I feel a bit lonely sometimes," he says. On campus Wang spends more time on exploring his skills. Wang now regards playing weichi as a hobby. He is the captain of the weichi team on campus, which has five members. He organizes them to research the latest formations once a week. Wang says his next project is to promote weichi among his peers on campus. "Many young people in China don't understand this kind of sports and I want to promote it," says Wang.
