Write a multi-choice question for the following article, with the given choices and answer: Article: An absolute description of the threat hanging over the world's mammals, reptiles, amphibians(, , ) and other life forms has been published by the well-known scientific journal, Nature. A special analysis carried out by the journal indicates that an astonishing 41% of all amphibians on the planet now face extinction while 26% of mammal species and 13% of birds are similarly threatened. Many species are already critically endangered and lose to extinction, including the Sumatran elephant, Amur leopard and mountain gorilla. But also in danger of vanishing for the wild, it now appears, are animals that are currently rated as merely being endangered. In each case, the finger of blame points directly at human activites The continuing spread of agriculture is destroying million of hectares of wild habitats every year, leaving animals without homes, while the introduction of newly-come species, often helped by humans, is also damaging native populations. At the same time, pollution and overfishing are destroying ocean ecosystems. "Habitat destruction, pollution or overfishing either skill off wild creatures and plants or leaves them badly weakened," said Derek Tittensor, an ocean ecologist at the World Conservation Monitoring Centre in Cambridge. "The trouble is that in coming decades, the additional threat of worsening climate change will become more and more common and could then kill off these survivors." The problem, according to Nature, is worsened because of the huge gaps in scientists knowledge about the planet's biodiversity. Evaluations of the total number of species of animals and plants alive vary from 2 million to 50 million. In addition, evaluations of current rates of species' disappearances vary from 500 to 36, 000 a year. "That is the real problem we face," added Tittensor. "The scale of uncertainty is huge." In the end, however, the data indicate that the world is heading cruelty towards a mass extinction-which is defined as one involving a loss of 75% of species or more. This could arrive in less... Options: A mass extinction B extinction rates C extinction time D 75% of species or more Answer: A mass extinction Question:

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Celia was shocked. She had always been in good shape during high school, but now, in her first year of college, she was suddenly ten pounds heavier. "My friends and I often had pizza or ice cream when we studied late at night," she said, "and I was always drinking Coke to stay awake." Celia's experience is common. Many students enter college and find it so different that they cannot deal with changes properly. They're away from their parents and in a new stressful environment. Pressures together with freedom to sleep and eat however they please cause many students to experience the "Freshman 15": gaining weight suddenly in their freshman year of college. Most students do not realize that the "Freshman 15" can cause some serious health problems. Of course, college-age adults are still developing bone mass, so gaining some weight is normal. Sudden weight gain, however, puts too much strain on the heart and lungs, resulting in little energy and some difficulty thinking and remembering. In later life, it can lead to heart disease, diabetes, obesity, and possibly cancer. The solution to the "Freshman 15" is simple--pay attention to developing good habits! In general: * Eat normal-sized meals at regular times. Eat slowly and enjoy it, so you don't need to go back for more. * Keep only healthy snacks in your room--and don't snack too often! * Control drinking and smoking. Alcohol has a lot of calories, and smoking too much makes exercise difficult. * Exercise regularly! Even just 30 minutes a day--such as walking quickly to class from your dorm--will make a big difference! Options: A They find it quite different. B They find it not quite difficult. C They find it very free. D They find it simple. Answer: A They find it quite different. Question:
A: What do many students think of their freshman year of college?

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Around the world coral reefs are facing threats brought by climate change and great changes in sea temperatures. While ocean warming has been the primary focus for scientists and ocean policy managers, cold events can also whiten corals. A new study by scientists compared damaged to corals exposed to heat as well as cold stress. The results show that cool temperatures can cause more damage in the short term, but heat is more destructive in the long run. Climate change is widely known to produce warming conditions in the oceans, but extreme cold-water events have become more frequent and serious as well. In 2010, for example, coral reefs around the world faced on of the coldest winters and one of the hottest summers on record. During a unique experiment, corals under cold temperatures suffered greater damage in just days compared with heat treated corals. Yet the researchers found that corals were eventually able to adjust to the cold conditions, make their health stable and continue to grow. However, over the long term corals subjected to heat suffered more greatly than those in cold, with evidence of severe whitening and growth stoppage, which leads to death. The coral's ability to adjust to cool temperatures surprised the researchers, who say the study's results show the complexities of monitoring coral health in response to different environmental factors . "Global warming is associated with increases but also decreases of temperatures," said Deheyn, one of the researchers. "Not much has been known about the comparative effects of temperature decrease on corals. These results are important because they show that corals react differently to temperature differences, which is important for future management of coral reefs in the field of climate change." Options: A corals may continue to grow in cold events after a few days B cold events help corals grow more quickly in a short time C corals show no response to hot temperatures in the first days D corals are whitened mainly because of warm temperatures Answer: A corals may continue to grow in cold events after a few days Question:
Answer: According to the research, _ .

Write a multi-choice question for the following article, with the given choices and answer: Article: Are animal brains too simple for thoughts and choices? Stories about animal kindness have really changed my point of view. In fact, some stories are amazing, especially when animals are meeting with people. Here are two stories that interest me. James, a wildlife writer, told a story that an African woman had placed her baby in the shade of a tree while she was working. An elephant group walked by and saw the baby. Several elephants pulled leafy branches from the tree covered the sleeping baby. Flies can be a problem in Africa and the branches protected the baby from the flies. The elephants were so gentle and quiet that they did not even wake up the baby. Then the elephants walked away. An English magazine offers another story. Bill, a cat, stayed at home while its master was away on a trip, but the man was injured in a railway accident and died a few days later in a hospital. At the funeral, the Man's brother was surprised to see that Bill was there. The faithful cat had traveled a long way to the hospital, looked at the coffin , and then sadly returned home. Humans are only one part of the earth. The beautiful flowers are our sisters; the deer, the horses and the great eagles, these are our brothers. The sky and mountains, the cows and men, all belong to the same family. These stories, I hope, will inspire more people to treat animals as our friends rather than pets or our next meal. Options: A He wants to make animals become our sisters and brothers. B He wants to inspire more people to treat animals as friends. C He wants to warn people against having more food or pets. D He wants to make readers know the elephants and the cat. Answer: B He wants to inspire more people to treat animals as friends. Question:
