Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Many people go to school for an education. They learn languages, history, politics, geography, physics, chemistry and mathematics. Others go to school to learn a skill so that they can make a living. School education is very important and useful. Yet, no one can learn everything from school. A teacher, no matter how much he knows, can not teach his students everything they want to know. The teacher's job is to show his students how to learn. He teaches them how to read and how to think. So, much more is to be learned outside school by the students themselves. It is always more important to know how to study by oneself than to memorize some facts or a formula . It is actually quite easy to learn a certain fact in history or a formula in math. But it is very difficult to use a formula in working out a math problem. Great scientists before us didn't get everything from school. Their teachers only showed them the way. Edison didn't even finish primary school. But they were all so successful. They invented so many things for mankind. The reason for their success is that they knew how to study. They read books that were not taught at school. They would ask many questions as they read. They did thousands of experiments. They worked hard all their lives, wasting not a single moment. Above all, they knew how to use their brain. Options: A only a certain formula B a certain fact C some facts D the way to solve it Answer: D the way to solve it Question:

A: To work out a math problem, you need to know _ .

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: 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. Options: A too much homework B pressure from parents C TV and computer games D parents' bad sleeping habits Answer: D parents' bad sleeping habits Question:
++++++++++++++++++++++++++++++++
The answer is:
Scientists worry that _ may cause children to sleep less.
