Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: As a young man, Paul Beier hiked in the mountains of California. Since then, he has decided to choose his career as a wildlife protector. He went to school to learn more first of all. After he earned his doctor's degree, he eagerly signed up for a job studying cougars , which once lived throughout the United States, but now live mainly in the Rocky Mountains and westward. They need not only a lot of land to survive but also plenty of food and places to raise their young. But many wild areas have been divided by freeways and taken over by towns. The small wilderness areas of the Santa Ana Mountains in Southern California didn't have much room for them. And yet a few still lived there. How did they do it? Many big animals are disappearing. Those that survive are being trapped in shrinking patches of habitat. A patch may not have enough space or food for a cougar to survive. Scientists wondered if cougars could move from one patch to another. If so, maybe humans could preserve wildlife corridors to connect the patches, providing enough room for the animals. But no one had shown that animals use wildlife corridors in real life. To see if cougars had found corridors through local suburbs and freeways, Paul and his research team studied 32 cougars for five years. They used a drug to make each cat sleep, buckled a radio collar around its neck, and let it go. Every day, Paul used an electrical device that sends and receives radio signals to find cougars, listening for radio beeps from their collars. Once or twice a week, he trailed one of the cougars all night. He traced their travels on a map. Sure enough, some of them had discovered paths from one small park land to the next. One cougar became famous for his travels. He was named M6:"M"for Male, and"6"because he was the sixth one collared in the study. M6's corner of the Santa Ana Mountains wasn't large enough for him. Chino Hills State Park was not far away, but the trip was not safe. After dark, M6 used a paved vehicle underground passage to cross undera busy... Options: A see how cougars found and used corridors B draw the regular routine cougars moved C prove cougars were better at finding food D know how human activities influenced cougars Answer: A see how cougars found and used corridors Question:

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Cities need to put efforts to deal with pollution and clear the air. Chinese cities will need to put efforts to clear up the sky when a new department to improve regional air quality is set up by 2015, according to the latest plan released by the State Council. Besides the existing pollution control program for SO2, regional emission caps for other certain chemicals will be established in the three key air polluting areas-- the Yangtze River Delta, Pearl River Delta and the Beijing-Tianjin-Hebei region. Coal-consumption caps will also be tried out in some areas, according to the plan. "The plan is aimed at dealing with regional air pollution--such as acid rain and smog--which have become increasingly obvious in China in recent years and caused a severe threat to people's health," Zhang Lijun, vice-minister of environmental protection, said in an interview on Monday. "The air quality in a city affects the regions nearby because pollutants Can travel through the atmosphere," said Chai Fahe, vice-director of Chinese Research Academy of Environmental Sciences. "So efforts to reduce air pollution in a single city, targeting a certain pollutant will not be enough," Chai said. Zhang said, "The country's major industrial districts--the Yangtze River Delta, Pearl River Delta and the Beijing-Tianjin-Hebei region--have recorded more than 100 misty days annually in recent years." These three regions, home to at least 200 million people, occupy only 6. 3 percent of the country's area but consume 40 percent of the country's coal and produce half of its steel, according to official figures. Studies also show that the visibility in eastern regions of China has dropped by 7 to 15 km compared to that in the early 1960s, as a result of air pollution. Liaoning province, the Shandong Peninsula, Wuhan in Hubei province and its surrounding area, the Changsha-Zhuzhou-Xiangtan region in Hunan province, the Chengdu-Chongqing region, and the western coast of the Taiwan Straits are also listed as areas to carry out such regional... Options: A to inform readers of the damage caused by air pollution B to introduce the new plan to control air pollution C to provide official figures of air pollution levels D to point out the regions affected by air pollution Answer: B to introduce the new plan to control air pollution Question:???

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Although man has known asbestos for many hundreds of years, it was not until 160 years ago that it was mined for the first time on the North American continent. H. W. Johns, owner of a New York City Supply Shop for roofers , was responsible for(...) the opening of that first mine. Mr. Johns was given a piece of asbestos which had been found in Italy. He experimented with the material and then showed its surprising powers to his customers. After putting on a pair of asbestos gloves, which looked much like ordinary work gloves, he took red-hot coals from the fireplace and played with them in his hands. How astonished the customers were to discover that he was not burned at all. You can well imagine that he had increasing business in asbestos roofing materials. However, because it was very expensive to transport (carry) them from Italy to the United States, Mr. Johns sent out a young scientist to seek a source nearer home. This young man found great vein , in the province of Quebec in Canada. Ever since 1881 Quebec has led the world in the production of this unusual mineral, which is made up of magnesium, silicon, iron, and oxygen. When it is mined, the asbestos is heavy, just as you would expect a mineral to be. When it is separated, a strange thing happens; the rock breaks down into fine, soft, soapy fibres . Scientists do not know why the rock can be separated easily into threads , but they have found thousands of users of this fireproof material, of the so-called "cloth of stone". Options: A Asbestos mined in Canada B Fireproof matter C A "wonder" mineral D A new roofing material Answer: C A "wonder" mineral Question:
