I'm taking a test and have to guess the right answer to the question after the article. 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... Question: Scientists guess cougars could survive in the Santa Ana Mountains mainly because . Options: A: they found plenty of food there B: their living areas weren't divided by freeways C: nobody disturbed them when they raised their babies D: they succeeded in finding more food and places to survive

I'm taking a test and have to guess the right answer to the question after the article. 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... Question: . Suppose the visibility in eastern regions of China was 130 km in the early 1960s, the visibility there nowadays is _ . Options: A: 123 to 115 km B: 137 to 145 km C: 123 to 145 km D: 115 to 137 km

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: There were smiling children all the way. Clearly they knew at what time the train passed their homes and they made it their business to stand along the railway, wave to complete strangers and cheer them up as they rushed towards Penang. Often whole families stood outside their homes and waved and smiled as if those on the trains were their favorite s. This is the simple village people of Malaysia. I was moved. I had always traveled to Malaysia by plane or car, so this was the first time I was on a train. I did not particularly _ the long train journey and had brought along a dozen magazines to read and reread. I looked about the train. There was not one familiar face. I sighed and sat down to read my Economics. It was not long before the train was across the Causeway and in Malaysia. Johore Baru was just another city like Singapore, so I was tired of looking at the crowds of people as they hurried past. As we went beyond the city, I watched the straight rows of rubber trees and miles and miles of green. Then the first village came into sight. Immediately I came alive; I decided to wave back. From then on my journey became interesting. I threw my magazines into the waste basket and decided to join in Malaysian life. Then everything came alive. The mountains seemed to speak to me. Even the trees were smiling. I stared at everything as if I was looking at it for the first time. The day passed fast and I even forgot to have my lunch until I felt hungry. I looked at my watch and was surprised that it was 3:00 pm. Soon the train pulled up at Butterworth. I looked at the people all around me. They all looked beautiful. When my uncle arrived with a smile, I threw my arms around him to give him a warm hug . I had never done this before. He seemed surprised and then his weather-beaten face warmed up with a huge smile. We walked arm in arm to his car. I looked forward to the return journey. Question: What can we learn from the story? Options: A: Comfort in traveling by train. B: Pleasure of living in the country. C: Reading gives people delight. D: Smiles brighten people up.
