Question: Read the following article and answer the question. Article: This is a tale of two friends --- one is blind, the other has no arms. On their own, the two are "disabled". But together, they are a powerful team that has changed part of their village in North China's Hebei Province into a rich, green forest. Meet 53-year-old Jia Haixia and Jia Wenqi! Their story began in 2000, when Haixia, who was already blind in his right eye, lost his left one after an illness. Wenqi lost his arms in an accident when he was just three. Neither could find a job, so the two decided to team up. They rented some poor land and began to plant trees. In return, the local officials paid them a small fee. Haixia and Wenqi never imagined that they would end up creating an environmental paradise. Their forest now has over 10,000 trees, hundreds of birds and many other wild animals. In addition, it saves the village from river flooding during the rainy season. When the friends work together, they focus on their strengths not their disabilities. Their day begins at 7 a.m. when the sightless Haixia carries Wenqi across the river to get to their worksite. Since they cannot afford to buy young trees to plant, the two use branches from existing trees. Haixia climbs to the tree-top and with Wenqi's direction, selects the perfect branch. He then digs a hole and carefully plants it. Finally Wenqi waters the area. Though hard-working, the men don't make much money. But as Wenqi puts it, " _ ." Neither Haixia nor Wenqi cares about money. Together, they already have everything they need --- a perfect pair of eyes, two strong hands, and the best friendship in the world! Question: Haixia and Wenqi's forest has helped the village by _ . Answer:

- stopping floods in the rainy season
- increasing the number of tourists
- making the villagers richer
- providing more farmland
Answer: stopping floods in the rainy season

It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution.

Q: Read the following article and answer the question. Article: "How are you?" is a nice question.It's a friendly way that people in the United States greet each other,but "How are you?" is also a very unusual question.It's a question that often doesn't have an answer.The person who asks "How are you?" hopes to hear the answer "Fine", even if the Derson's friend isn't fine.The reason is that "How are you?" isn't really a question and "Fine",isn't really an answer.They are simply other ways of saying "Hello!" or "Hi!". Sometimes,people also don't say exactly what they mean.For example,when someone asks "Do you agree?".the other person might be thinking,"No,I disagree.I think you're wrong."But it isn't very polite to disagree so strongly,so the other person might say "I'm not so sure."It's a nicer way to say that you don't agree with someone. People also don't say exactly what they are thinking when they finish talking with other people.For example,many talks over the phone finish when one person says "I have to go now."Often,the person who wants to hang up gives an excuse:"Someone's at the door.""Something is burning on the stove."The excuse might be real,or it might not.Perhaps the person who wants to hang up simply doesn't want to talk any more,but it isn't polite to say that.The excuse is more polite,and it doesn't hurt the other person. Whether they are greeting each other,talking about an idea,or finishing a talk,people often don't say exactly what they are thinking. It's an important way that people try to be nice to each other,and it's part of the game of language. Question: When a person in the United States asks "How are you?". he or she wants to hear" _ ". Answer:

OPTIONS:
- How are you?
- Hello.
