*Question*
I'm taking a test and have to guess the right answer to the question after the article. Article: Indonesia's coral reefs are in trouble. Coral mining, Industrial pollution and poisonous agricultural runoff all play a role in their destruction, but the fishermen have been the worst offenders. They not only bomb fish but also poison them with cyanide, an equally destructive practice. The fishermen are also among the biggest potential victims . Two thirds of Indonesia's 7, 000 coastal villages are close to coral reefs and thus depend for their livelihood on the harvest of reef fish. The disappearing reefs are already leading to a dramatic decline in the productivity of coastal fisheries and to increasing fights among fishermen. Indonesia's reefs are vast - they cover 51, 000 square kilometers, surround 17, 500 islands and stretch 3,500 kilometers - but they are not infinite. Many foreign experts and Indonesians fear that the region's entire marine environment could be seriously damaged if the reefs keep dying at their present rate. "The overall picture is depressing," says Ian Dutton, Indonesian director of an environmental group. Depressing, but not hopeless. Despite the destruction, environmentalists have in recent years made significant progress in changing the hearts and minds of the fishermen. Working closely with local Indonesian authorities in North Sulawesi and less populated eastern Indonesia, where most of the country's reefs are located, they have succeeded in preventing destructive fishing practices and coral mining from overwhelming the reefs. Increasing numbers of fishermen are waking up to the threat and protecting the life-sustaining coral before it's too late. Nuhung, a 56-year-old fisherman, says, "I always knew blast fishing was harmful. Then I suddenly realized that by bombing the reefs I was destroying not only my own but my children's future." Question: The fishermen are named "worst offenders" because_. Options: A: they defend their rights of mining the coral reefs too eagerly B: they wake up too late to realize the terrible situation C: they use the fishing ways, which destroy the coral reefs D: they pretend to follow the government's rules

*Question*
I'm taking a test and have to guess the right answer to the question after the article. Article: The oddness of life in space never quite goes away. Here are some examples. First consider something as simple as sleep. Its position presents its own challenges. The main question is whether you want your arms inside or outside the sleeping bag. If you leave your arms out, they float free in zero gravity, often giving a sleeping astronaut the look of a funny balled dancer. "I'm an inside guy," Mike Hopkins says, who returned from a six-month tour on the International Space Station. "I like to be wrapped up." On the station, the ordinary becomes strange. The exercise bike for the American astronauts has no handlebars. It also has no seat. With no gravity, it's just as easy to pedal violently. You can watch a movie while you pedal by floating a microcomputer anywhere you want. But station residents have to be careful about staying in one place too long. Without gravity to help circulate air, the carbon dioxide you exhale has a tendency to form an invisible cloud around you head. You can end up with what astronauts call a carbon-dioxide headache. Leroy Chiao, 54, an American retired astronaut after four flights, describes what happens even before you float out of your seat,"Your inner ear thinks your're falling . Meanwhile your eyes are telling you you're standing straight. That can be annoying--that's why some people feel sick." Within a couple days --truly terrible days for some --astronauts' brains learn to ignore the panicky signals from the inner ear, and space sickness disappears. Space travel can be so delightful but at the same time invisibly dangerous. For instance, astronauts lose bone mass. That's why exercise is considered so vital that National Aeronautics and Space Administration (NASA) puts it right on the workday schedule. The focus on fitness is as much about science and the future as it is about keeping any individual astronauts return home, and, more importantly, how to maintain strength and fitness for the two and a half years or more that it would take to make a round-trip to Mars. Question: What is the major challenge to astronauts when they sleep in space? Options: A: Deciding on a proper sleep position B: Choosing a comfortable sleeping bag C: Seeking a way to fall asleep quickly D: Finding a right time to go to sleep.

*Question*
I'm taking a test and have to guess the right answer to the question after the article. Article: Waiting anxiously to be reunited with the son he had not seen for 13 years, Phil Baker took a walk along the beach with his wife Lyn to relax himself. His boy Benji, 21, was finally back to Australia after living most of his life in the UK, half a world away from his dad. As he looked out at the ocean, wondering how his son might have changed over the years, Phil saw some people on the kayaks in trouble on the water. Without hesitation, he dived into the sea to help. And as he carried a stricken young man trembling and semi-conscious to the shore, he realized the young man was his long-lost son. "I looked at his face, and something occurred to me," says Phil. "Those brown eyes were very familiar." Although Phil had seen just a few photos of his son since the boy was eight years old, he recognized him at once. It would be reasonable to suppose it was a father's instinct that _ Phil to help ---- but at the moment he dived into the water to go to the aid of the struggling group, he only thought he was helping a stranger in trouble. He said, "Two people were desperately paddling on one of the kayaks and it seemed like someone fell into the water. I told Lyn, 'Something is not right; I'm going to help.' " "l took off my T-shirt and threw my keys on the sand. Diving into the water, I saw there were two instructors on board and a man lying in the water. He was shaking violently. Linking arms with one instructor, I helped to carry the man out of the water. He was drifting in and out of consciousness and his hands and feet were blue." Then Phil looked into the boy's eyes and wept as he realized the stricken stranger was his own son. Phil recalled, "I asked the instructor, 'what's his name?' " He replied, 'Benji'. In an instant, I knew that stranger was my boy. I checked his breathing and pulse and said, "It's me, your dad. You're going to be OK." Benji tells how it felt to be saved by his long-lost dad. "All I remember was waking up on the beach and seeing my dad there," he says, "And I recognized his face straight away." Question: What can we know about the Bakers? Options: A: Phil and his wife lived in Australia. B: Phil knew he was going to save his son. C: Benji was going to see off his son on the beach. D: Benji and Phil were separated because of Benji's education.
