Question: Write a multi-choice question for the following article: Article: Scientists have discovered a special biological behavior in dolphins that could lead to a treatment for late-onset diabetes in humans. Studies on dolphins found that healthy dolphins switch into a diabetic-like state overnight when they are not feeding, but return to normal when they eat the following morning. The extraordinary finding has led scientists to suggest that dolphins have "genetic switch" that allows them to imitate diabetes while they are not feeding for a night, without suffering any ill effect. If researchers can identify a similar genetic pathway in human, they may be able to develop drugs to effectively switch off diabetes. Some 2.2 million people in Britain have type 2 (or late-onset) diabetes, a figure that is expected to reach 4 million by 2025 as a consequence of rising levels of obesity . The tissues of people with type 2 diabetes have become resistant to insulin so they lose the ability to control sugar levels in their blood. The condition can damage the heart, eyes, kidneys and nerves and contribute to 5% of all deaths, according to the World Healthy Organization. Dolphins appear to imitate diabetes to keep high levels of blood sugar when food is rare. Like humans, dolphins need some sugar in their blood for their brains to function normally. Venn-Watson's team analyzed 1,000 blood samples from 52 dolphins while they didn't eat anything overnight and fed in the morning. At night time, the dolphins' metabolism changed greatly and showed similar characteristics to that seen in people with type 2 diabetes. "It is our hope that this discovery can lead to new ways to prevent, treat and maybe even cure diabetes in humans," said Stephanie Venn-Watson, director of clinical research at the National Marine Foundation in San Diego.
Answer: Question: The key to applying the finding to curing human diabetes lies in _ .Options:A producing insulin in a larger amountB developing drugs from healthy dolphinsC identifying a similar genetic pathway in humanD analyzing more blood samples from hungry dolphinsAnswer:C

Question: Write a multi-choice question for the following article: Article: I always feel sorry for world leaders busy dealing with fights between nations. When my three children were young, most days it was hard to keep my house from becoming a battlefield. It got worse as they grew older. Three years ago, Zack, then 16, couldn't make it through a day without making his sisters, Alex 11 and Taryn 9, angry. My husband and I tried to be understanding the boy at such an age. We reasoned, punished, and left heartfelt notes on his bed about how he was hurting our family. His answer was "I say it because it's true." I even tried telling the girls to fight back. Bad idea. Now I had three children at war. Whatever I said to them, they paid no attention. When there was no way out, I told everything to my sister in an e-mail. She replied, "Don't e-mail me. E-mail him." Our son was online every day, mailing and talking with his friends. Maybe he would actually hear me this way. I didn't say anything different, but e-mail just took the tension away. There'd be no shouting or door banging. Zack wouldn't feel under attack. Zack didn't reply for days. When he finally did, his entire message was four small words. I smiled when I read them, "You're right. I'm sorry." The children still fought, of course, but Zack changed. Best of all, I now have a better way to talk with not one but three of them. I like it that they don't _ as much as they used to. They like not having to listen to me shouting to them. Or as Alex says, "You're so much nicer online." All I know is that the house is quiet. But we're talking.
Answer: Question: The writer e-mailed her sister _ .Options:A to tell her about the family problemB hoping she'd e-mail the boyC asking about child-raisingD to reduce the tensionAnswer:A

Question: Write a multi-choice question for the following article: Article: Houses fall down. Trees fall over. Large holes form in the ground. Could Alaska be sinking? That's what some villagers in Alaska have been asking themselves recently--and scientists think they know why. Warmer temperatures may be causing Alaska's frozen ground to thaw . About 85 percent of Alaska's land surface has _ . Permafrost supports the ground above it--including trees, houses, and roads. But why is the permafrost thawing? Some scientists say that human-caused pollution is leading to global warming. And most scientists agree that Alaska has been getting warmer. They say that the warmer temperature is causing permafrost to thaw in some areas. The thawing permafrost can cause problems for people, plants, and animals. "The collapsing is a problem in the villages in Alaska which are built on permafrost, and some of them may have to move to safer ground, where there is no permafrost," Weller said. The Alaskan town of Glennallen saw its old post office collapse. And, according to James Walters, a permafrost expert at the University of Northern Iowa, house-moving companies have been very busy. "Melting permafrost can also destroy trees and forests," Weller said. "When holes in the ground form, trees fall into them and die. This could turn a forest into a swamp , and animals which need the forest will have to move elsewhere." The melting could cause "severe problems." Weller says: "This could take hundreds of years, but in the end Alaska will look quite different from what it looks like now."
