Question: Write a multi-choice question for the following article: Article: The first Beijing Fair of National Culture and Art kicked off August 3 and ran till August 12. The fair features more than 21 old Beijing business brands, more than 80 examples of intangible cultural heritage and 6 official Olympics merchandise. One of the highlights is a show featuring 15 lanterns. The fair aims at starting cultivating the cultural atmosphere for the Beijing Olympic Games, by highlighting the long history and culture of the city. The fair is divided into 12 districts and is open from 430--930 pm. There are both exhibitions and performances and interactive items tourists can enjoy. Sports competitions and craftmaking are available to teenagers, who can learn from old masters. Some of the most notable art elements include three luxury items worn by nobles in ancient China:a wooden craft called"pillow of Lu Ban", after a legendary civil engineer and carpenter who lived from 507--444 B.C., and whose designs are still used, and glass grapes. Some items are for sale and shoppers can hear about the history of the items from craftspeople. The lantern show includes 15 pieces installed along the park's main roads, providing both light and decor. There will be lantern shows accompanied by music and some lanterns feature designs including flowers, the moon and animal paintings. The fair also provides opportunities to teenagers to take part in interactive activities. For example, children can learn how to make dough figures from artist Wang Xingshan. They can also learn the art of papercutting, get some practice of braiding Chinese knots, and learn how to make sugar figures.
Answer: Question: The first Beijing Fair of National Culture and Art lasted  _  days.Options:A 9B 21C 8D 15Answer:A
[Q]: Write a multi-choice question for the following article: Article: People who drink moderately  , exercise, quit smoking and eat five servings of fruit and vegetables each day live on average 14 years longer than people who adopt none of these behaviors, researchers said on Tuesday.   Much evidence has shown these things contribute to healthier and longer lives, but the new study  actually quantified   their combined effect, the British team said.   "These results may provide further support for the idea that even small differences in lifestyle may make a big difference to health in the population," the researchers wrote in the journal PLoS Medicine. Between 1993 and 1997 the researchers questioned 20,000 healthy British men and women about their lifestyles. They also tested every participant's blood to measure vitamin C intake, which shows how much fruit and vegetables people ate. Then they assigned the participants aged 45-79 a score of between 0 and 4, giving one point for each of the healthy behaviours.   After allowing for age and other factors that could affect the possibility of dying, the researchers determined people with a score of 0 were four times as likely to have died. Also a person with a health score of 0 had the same risk of dying as someone with a health score of 4 who was 14 years older.   The lifestyle change with the biggest benefit was giving up smoking, which led to an 80 percent improvement in health, followed by eating fruits and vegetables. Moderate drinking and keeping active brought the same benefits.   With this information, public-health officials should now be better encouraging behavior changes likely to improve the health of middle-aged and older people.

input: Please answer the following: Write a multi-choice question for the following article: Article: Scientists recently found three animal species living two miles below the surface of the Mediterranean Sea, where the super-salty waters don't have oxygen . They're multicellular , which means their bodies have many cells. They each are as small as a large grain of sand. But they are animals. The most exciting thing about these creatures, say the scientists, is that they obviously don't need oxygen to live. What biologists know about life so far is that only single-celled living things can live in places that have no oxygen, and that multicellular organisms  can visit these places, but not live there. These newly found creatures could _ . Finding animals down there was so surprising that the scientists couldn't believe it. At first, "we thought they were dead bodies," Roberto Danovaro, a scientist at the Polytechnic University of Marche in Ancona, Italy, told Science News. To find out whether the animals could actually live there Danovaro and his colleagues brought up more samples  from the ocean floor. Studying the animals in the new samples showed that they appeared to be alive. The researchers did more tests, and found that some of the animals had eggs--which suggests they were reproducing . Also in the samples were old skins, suggesting that the animals had lived there long enough to grow. Finally, pictures taken showed that the insides of the animals appear to be adapted to live in an environment that has no oxygen. These clues suggest the animals don't need oxygen, but the evidence  is indirect, which means that scientists still have not observed how the animals live without oxygen. This means more studies are needed, but the scientists think they're on the right track. And if they're right, biologists will need to rethink what they know about where animals live.

input: Please answer the following: Write a multi-choice question for the following article: Article: Can people change their skin color1 without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin color1.     The gene comes in two versions, one of which is found in 99 percent of Europeans. The other is found in 93 to 100 percent of Africans, researchers at Pennsylvania State University report in the latest issue of science.     Scientists have changed the color1 of a dark-striped zebrafish to uniform gold by inserting a version of the pigment gene into a young fish. As with humans, zebrafish skin color1 is determined by pigment cells, which contain melanin  . The number, size and darkness of melanin per pigment cell determine skin color1.     It appears that, like the golden zebrafish, light-skinned Europeans also have a mutation   in the gene for melanin production. This results in less pigmented skin. However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebrafish genes.     Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun , which can cause skin cancer. But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng.     "Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin color1," said Cheng.     The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin color1 without damaging it like chemical treatment did on Michael Jackson. ks5u
