Write a multi-choice question for the following article, with the given choices and answer: Article: Are you an early riser or a night owl? Researchers from Aachen University in Germany believe that about 10 percent of people can be classified as "morning people", who feel more active and function best in the morning.Around 20 percent are night owls--people who naturally tend to stay up late and are more tired during the day.And the rest of us fall somewhere in between, according to New Scientist. Previous studies have suggested that early risers are more likely to be happy and healthy while night owls experience worse sleep as well as more depression and anxiety during the day. For a long time, scientists have been trying to find out what causes the differences between the two.A new study suggests that it isn't just people's habits--early risers and night owls actually have different brain structures. Led by Jessica Rosenberg at Aachen University, researchers scanned the brains of 16 early risers, 23 night owls and 20 people with intermediate sleeping hours.They found that the brains of night owls had less "white matter"--which speeds up the transmission of nerve signals -- in brain areas associated with depression. As you know, after people fly in an airplane from one time zone to another, they often suffer from a confused and tired feeling called "jet lag" because their body clocks are out of sync with the new time zone.It usually takes about a week for their bodies to adjust to the new time.But night owls always have difficulty syncing their bodies to the right time due to their brain structure."It's like they suffer from permanent jet lag," said Rosenberg. The good news is that it is possible for night owls to turn themselves into morning people.According to the researchers, night owls should try to spend as much time in the sunlight as possible and reduce their exposure to artificial light at night to force their body clocks to shift to a more normal rhythm. Options: A make up almost a third of the human population B have more white matter in their brains than other people C are more used to artificial night than sunlight D have body clocks that are not in agreement with the actual time Answer: D have body clocks that are not in agreement with the actual time Question:

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: It's hard to find Alice Munro in the media. Even after she won the 2013 Nobel Prize in Literature, the Canadian writer just appeared for a quick interview and then dropped out of sight. On Dec 29, she still didn't seek the spotlight when she was named one of the five Women of the Year by the Financial Times. In Munro's eyes, ordinary lives always hide larger dramas. So she records what we casually think of as the everyday actions of normal people. She often focuses on life in her hometown, a small village in Ontario which she is most familiar with. She writes about the ordinary things in the village-fox forming, trees filled in the Ontario wilderness, poor country alcohol and long last illnesses. Above all, she talks about girls and women who have seemingly ordinary lives but struggle against daily misfortune. She has a special talent for uncovering the extraordinary in the ordinary. These are ordinary people, ordinary stories, but she has the magic. Her precise language, depth of detail and the logic of her storytelling have made her stories inviting. Runaway, one of Munro's representative works, is a good example of her writing style. One of the stories centers on the life of an ordinary woman Carla, who lives in a small Canadian town with her husband Clark. The story slowly forms a picture of Carla, trapped in a bad marriage, her unhappiness building into desperation until she decided to flee. The story of Carla is a story of the power and betrayals of love. It is about lost children and lots of chances that we can all find in life, There is pain beneath the surface, like a needle in the heart. Since she published her first collection of short stories in 1968, Munro has won many awards, with the Nobel Prize being her biggest honor. On Oct 10, 2013, the Nobel Prize committee named Munro the "master of the contemporary short story". Options: A Alice Munro and her hometown B The awards Alice Munro won C Alice Munro and her writing style D Alice Munro's literary life Answer: C Alice Munro and her writing style Question:
A: What is the text mainly about?

Write a multi-choice question for the following article, with the given choices and answer: Article: Today, we know that the role of vitamins and minerals goes way beyond the prevention of deficiency diseases to actually preventing cancer and heart disease, the most fearsome killers of our time. With this knowledge has come the widespread call for nutritional supplementation -- and a confusing group of vitamin, mineral, and supplements lining the supermarket shelves. Far from contributing to better health, however, nutritional supplements threaten to turn a scientific breakthrough into a nutritional disaster. _ of vitamins and minerals -- especially vitamins A, C, and E-- would have consumers believe that the little vitamin pill in the bottle is all they need for good health. Take your vitamins in the morning, and you're covered. It's okay to eat fast foods for the rest of the day or skip meals to achieve today's fashionably skinny look. But vitamins and minerals are only one part of the nutritional puzzle. A diet rich in fiber and balanced in carbohydrates and protein is essential for good health. You can't get these things from a nutritional supplement. The focus on vitamin and mineral supplements may actually be robbing us of the full nutrition we seek. And no supplement can compare to the quality of nutrition found in natural sources. For example, our bodies turn carotenes from plant foods into vitamin A. Many supplements contain a single carotene, but natural sources are rich in many different carotenes. Many supplements contain a form of vitamin E that is made from chemicals, when natural vitamin E is more readily absorbed and used by the body. And science is still discovering the wealth of nutrients in foods. You'd be hard-pressed to find a supplement as nutritionally comprehensive and powerful as a balanced diet. Even if you could, you'd pay much more than if you got the same nutritional value from natural sources. But perhaps the greatest danger presented by nutritional supplements comes from the very real risks presented by self-medication. Anyone can walk into the market and buy as many... Options: A The knowledge of deficiency diseases. B The low prices of nutritional supplements. C The frighteningly high death rate from cancer and heart disease.
