Article: In America, most people don't get enough sleep. Children aged 5 to 12 are advised to sleep 10 to 11 hours every night, but most of them can't sleep that long. A study found that about 41 million American workers got less than six hours of sleep every night. Scientists worry that parents are passing their bad sleeping habits down to their children. In the study, Reut Gruber and some other scientists either added or reduced on hour of sleep for healthy children aged 7 to 11. They watched the children for five nights. They wanted to know if the amount of sleep can affect a child's behavior. Before the study began, students were asked to sleep the same amount of hours as usual. Their teachers were asked to record their behavior. After five nights of the records, scientists found that those who slept one hour less behaved worse than those who slept one hour more. Students with less sleep were more likely to feel sad and had more problems paying attention. The scientists chose to study children in their homes instead of in a laboratory, because they wanted to find out how everyday changes might affect children's behavior at school. "In the study, nobody became a talent, and nobody became crazy. But small changes in children can really make a big difference," says Gruber. Question: Scientists did the new study in order to know _ . Yes or no, is the answer "if the amount of sleep can affect a child's behavior"?
No

Ques: Article: "Who did this?" asked my teacher. Thirty children tried to think about not only what they had done, but also what our teacher might have found out. "Who did this?" she asked again. She never became angry, but she was this time. She held up a piece of broken glass and asked, "Who broke this window?" "Oh, oh," I thought. I was the one who broke the window. I did not do it on purpose . It was caused by a bad throw of a baseball. Why did it have to be me? If I admitted it, I would be in a lot of trouble. How would I be able to pay for a big window like that? "My father is going to get angry at me," I thought. I didn't want to raise my hand, but something much stronger than me pulled it up. "I did it," I said. Then I was silent. It was hard enough saying what I had. My teacher went to one of our bookshelves and took down a book. She then began walking towards my desk. I had never known my teacher to strike a student, but I feared she was going to start with me. "I know how you like birds," she said as she stood looking down at my face. "Here is the field guide about birds that you always _ from our school library. It is yours now. We have got a new one for the school. You will not be punished . But remember, it's only for your honesty." I couldn't believe it! I wasn't being punished and I was getting my own bird field guide, the one that I had been saving up all my money to buy. Question: The writer mainly wants to tell us that _ . Yes or no, is the answer "he who is honest is wise"?
Ans: No
