Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: A Brown University sleep researcher has some advice for people who run high schools: Don't start classes so early in the morning. It may not be that the students who at their desks are lazy. And it may not be that their parents have failed to enforce bedtime. Instead, it may be that biologically these sleepyhead students aren't used to the early hour. "Maybe these kids are being asked to rise at the wrong time for their bodies," says Mary Carskadon, a professor looking at problem of adolescent sleep at Brown's School of Medicine. Carskadon is trying to understand more about the effects of early school time in adolescents. And, at a more basic level. she and her team are trying to learn more about how the biological changes of adolescence affect sleep needs and patterns. Carskadon says her work suggests that adolescents may need more sleep than they did at childhood, no less, as commonly thought. Sleep patterns change during adolescence, as any parent of an adolescent can prove. Most adolescents prefer to stay up later at nigh and sleep later in the morning. But it's not just a matter of choice -their bodies are going through a change of sleep patterns. All of this makes the transfer from middle school to high school--which may start one hour earlier in the morning ---- all the more difficult , Carskadon says. With their increased need for sleep and their biological clocks set on the "sleep late, rise late" pattern, adolescent are up against difficulties when it comes to trying to be up by 5 or 6 a.m. for a 7:30 a.m. first bell. A short sleep on a desktop may be their body's way of saying. "I need a timeout." Options: A Adolescents depend more on their parents. B Adolescents have to choose their sleep patterns. C Adolescents sleep better than they did at childhood. D Adolescents need more sleep than they used to. Answer: C Adolescents sleep better than they did at childhood. Question:

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: One morning, I stepped out of bed and put my feet on the floor. Suddenly, a mean little man jumped out from under the bed and stabbed (,) an ice pick through my left foot. Figuratively speaking, yes. I took another step and he stabbed it again. This went on all day. Step, stab, scream. Over the next few days, I started limping . My whole body hurt. Even my hair. I kept thinking that the little man would get tired of stabbing me and go pick on somebody else.We often take things for granted until we lose them or they start to hurt. My brother deals with pain every day. He's also blind and suffers from cerebral palsy , needs a walker to walk, doesn't take much for granted. I had to wonder: What would he think about my foot? Finally, after a week of pain, I went to see a very nice foot doctor. The doctor studied my foot, took X-rays, shook his head, and said the little man's name: Arthur Itis, or Arthritis . I knew it well. I'd often heard it hissed angrily by my grandparents and parents, all attacked by Arthur's ice pick when they got older. "Wait," I said. "Doesn't Arthur usually just pick on old people?" The doctor smiled, looking at my chart. "How old are you?" I gave him a look. "Never mind," I said. "Can you fix it?" "Well," he said, "we can try." He listed several options and I chose the injection . It didn't hurt much. Not half as much as the ice pick. That was yesterday. This morning, I awoke, took a few careful steps and ... hallelujah!It hurt just a bit, but no ice pick. I looked under the bed. No sign of Arthur. Maybe he was hiding in the closet, waiting for another day.But for now, he was gone, and I was grateful.My mind began to race with plans to do all the things I'd been putting off for days:unpack, clean the house, wash my hair ... Then it hit me. Another stab. Not in my foot. In my heart. I remembered that I hadn't called my brother in a long time. It's easy to take some things for granted. But it should never be the people we love. Options: A The author. B The author's brother. C The author's parents. D The author's grandparents. Answer: B The author's brother. Question:

A: Who had a disease that was different from the other people mentioned?

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: They like using the Internet. They have lots of pocket money to spend. And they spend a higher proportion of it online than the rest of us. Teenagers are just the sort of people an online seller is interested in, and the things they want to buy-games, CDs and clothing-are easily sold on the Web. But paying online is a tricky business for consumers who are too young to own credit cards. Most have to use a parent's card. They want a facility that allows them to spend money. That may come sooner than they think: new ways to take pocket money into cyber space are coming out rapidly on both sides of the Atlantic. If successful, these products can stimulate online sales. In general, teenagers spend huge amounts: $153bn (billion) in the US last year and PS20bn annually in the UK. Most teenagers have access to the Internet at home or at school-88 percent in the US, 69 percent in the UK. According to the Jupiter Research, one in eight of those with Internet access has bought something online-mainly CDs and books. In most cases, parents pay for these purchases with credit cards, an arrangement that is often unsatisfactory for them and their children. Pressing parents to spend online is less productive than pressing on the high street. They are more likely to ask "Why?" if you ask to spend some money online. One way to help teenagers change notes and coins into cybercash is through prepaid cards such as InternetCash in the US and Smart cards in the UK. Similar to those for pay-as-you-go mobile telephones, they are sold in amounts such asPS20 or $50 with a concealed 14-digit number that can be used to load the cash into an online account. Options: A Online shopping traps. B Internet users in the US and the UK. C New credit cards for parents. D The arrival of cyber pocket money. Answer: D The arrival of cyber pocket money. Question:
A:
What is the passage mainly about?
