Q: I'm taking a test and have to guess the right answer to the question after the article. Article: There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution. Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil) is creating a "greenhouse effect"-- conserving heat reflected from the earth and raising the world's average temperature. If this view is correct and the world's temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be in water. Another view, less widely held, is that increasing particular matter in the atmosphere is blocking sunlight and lowering the earth's temperature -- a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. Today we do not know for sure that either of these conditions will happen (though one recent government report drafted by experts in the field concluded that the greenhouse effect is very possible). Perhaps, if we are lucky enough, the two tendencies will _ each other and the world's temperature will stay about the same as it is now. Driven by economic profits, people neglect the damage on our environment caused by the "advanced civilization". Maybe the air pollution is the price the human beings have to pay for their development. But is it really worthwhile? Question: This passage is primarily about _ . Options: A: the greenhouse effect B: the burning of fossil fuels C: the potential effect of air pollution D: the likelihood of a new ice age
A: C

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Born with easy-broken bone disease, Zhang Yonghong is only half a meter tall and must use a wheelchair. His thin arms and legs can hardly support any weight, and he is unable to take care of himself. However, his hands are able to produce fine paper-cuts, which will free his daughter from the same disease. To support himself, he learned how to make paper-cut art from his mother. He sold his artwork and taught his techniques in Xi'an for eight years before discovering his young daughter _ the disease from him, leading Zhang to move his family to Beijing for his daughter's better treatment five years ago. The daughter's treatment costs about 30,000 yuan a year. The family's savings was used up in two years, and Zhang was forced to start to sell his work in underground passages with his healthy wife, who soon left him because of the hard life. With a little help from government, he was lucky to meet some kindhearted people in Beijing. A Hong Kong businessman gave 60,000 yuan to him last year to treat the girl and start a small shop on Qiangulouyuan, which is known as a famous hutong that attracts lots of tourists over holidays. Zhang Rui, a university graduate, spends most of her time helping Zhang sell the paper-cuts, translating the stories of the paper-cuts into English and selling the works on the roadside of Nanluoguxiang. However, the artist still lives beyond his income and struggles to continue his small business. "Selling paper-cuts is his only source of income. Without this, he can't support the family and treat his daughter," says Zhang Rui, who hopes more people will help Zhang. Question: Why did Zhang grow only half a meter tall? Options: A: His easy-broken bone disease affected him. B: His parents also had the same disease. C: His poor family couldn't provide him with rich food. D: An unexpected accident caused him to grow slowly.
A: A
