Article: Science, as we think, was born when the Greek philosopher ( ) Thales ( about 640-546 B.C.) asked a difficult question: What makes up our universe? No one had a ready answer, so Thales went on studying the earth around him, the sky and the stars. He saw so much water on earth and so much water falling from the sky as rain that he decided water must be the basic substance ( ) of the universe. Other Greek thinkers became interested in this question. They suggested other answers. One said that because air lies around the earth, it must be air that makes up all things. Another said that fire, appearing in different forms, was the building block of the universe. The Greek philosophers were feeling their way towards the ideas on which chemistry is based. Centuries later, scientists proved that the universe is made up of certain basic substances. But the list is much more _ than the Greeks realized. We now know of 103 basic substances which we call " elements ( )". Question: Thales, the famous Greek philosopher, died when he was about _ . Yes or no, is the answer "94 years old"?
Yes

Article: In some children who go blind, certain parts of the brain that normally control vision appear to switch jobs and focus instead on sound, a new study has found. The study, by researchers at the University of Montreal, involved 7 adults who could see and 12 adults who had lost their vision when they were children. Each participant sat in a room with 16 loudspeakers at different locations. The room was designed so that there were no echoes During the experiment, the speakers irregularly produced sounds. Participants had to point to where the sounds were coming from. Meanwhile, the researchers monitored blood flow in the brains of the participants to see which brain structures were working during the task. The results showed that five of the blind participants were very good at pointing to where sounds were coming from. In these people, blood flow increased in the visual cortex --- an area at the back of the right side of the brain. This part of the brain is usually associated with vision. The other seven blind participants showed no increase in activity in the visual cortex. These people didn't do very well at picking out where sounds were coming from. Now, the researchers are looking at whether these people have gained an enhanced sense of touch instead of sound to replace their lost vision. The scientists say that their study shows how adaptable parts of the brain can be. Question: The participants of the experiment were asked _ . Yes or no, is the answer "to identify the direction the sound came from"?
No

Q: Article: Mark Twain left school when he was twelve. He had little school education but had to live. He made millions of dollars by writing whose real name was Samuel Langhorne Clemens, but he is better known all over the world as Mark Twain, his penname.

Then, he worked as a printer, a river-boat pilot and later joined the army. But shortly after that he became a miner. During this period, he started to write short stories.

Question: Article: I was giving the class when her giggling drew my attention. Walking over to the young trouble-maker, I asked for the note in her hands. It was a had-drawn picture of me, teeth blackened, nostrils upwards, and the words "I'm stupid" coming out of my mouth. I managed to fold up the picture calmly and continue the class. My mind, however, was working angrily. I knew the two most likely suspects for drawing the picture. Maybe it was high time that I taught them a lesson! Somehow, in the very moment of real hurt and anger, I asked myself very softly, "How can I ever bring good out of this?" When there were about six minutes left of the class, I showed the kids the picture. The whole class was silent. I told them there must be a reason behind such a picture and that now was their chance to tell me the reason. Then I let them write silently while I stood sadly in the back of the classroom. Most of them either blamed the artist or felt sorry. But two notes, from the girls I figured were behind the picture, had a list of issues. I was too mean and too strict. Reading those notes, I realized that where I thought I was driving them to success I was actually driving them away. I had some apologizing to do. When the kids walked into my classroom the next day, one boy and one girl each handed me a card. The one signed by all the boys expressed sincere regret for the ugly joke. The one from the girls asked for forgiveness. I was extremely surprised. And more than a little shameful. I had my little speech all ready to give to the kids, but they did it before me. Question: Why did the teacher give up punishing the students who drew the picture? Yes or no, is the answer "Because she didn't think it would do any good."?
Answer: No

Article: Aside from doing schoolwork and studying, American students must also participate in various extra-curricular activities. Many students get involved in their communities by doing volunteer work at various local organizations. In fact, the school I attend even requires students to perform a certain number of hours of volunteer work per semester. It is part of our study hall grade, as well as a graduation requirement. There are many places to do volunteer work in the community. Some of my classmates volunteer at the local animal shelter, the community table (which provides free meals for needy families), charity stores, and many others. Finding a suitable place to volunteer usually depends on what's available, as well as personal interests. For example, a friend of mine who enjoys swimming volunteers at the recreation center to teach young children how to swim. With all these options out there, I ended up doing most of my volunteer work at a school library and a non-profit bookstore called Friends of the Library. This bookstore sells donated books at cheap prices, and all the profits made are donated to the local library. I thought it was very fitting that I do my volunteer work at a library and a bookstore, because reading has always been very important to me. I love working in the bookstore now, because every sale we make helps our public library expand, and gives it the funds needed to purchase new books. I think everyone should have the opportunity to read, and that we each should do our part to help those who don't have the chance. There is a charity event, called One Book for A Window of Opportunity, in which Chinese students can donate a book to the children of the poor village Fangmaping. They don't have a lot of resources, so reading can be a challenge. To find out more about this event, please visit: http://bbs.enfamily.cn/thread-739278-1-1.html. Question: This passage is supposed to write to _ . Yes or no, is the answer "Chinese readers"?
Yes
