input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Do you know why you sleep? You may think it's because you're tired. Or perhaps you've been told sleep is good for you. Yet no one knows exactly why or how people sleep. Until the early 1950s, most scientists thought the body and brain rested during sleep. Then a scientist watched people sleep. He noticed that during periods of between 5 and 30 minutes each, sleepers' eyes made rapid movements, as if they were watching something. He called these periods REM sleep, for Rapid Eye Movement. Periods when sleepers' eyes did not move he called non-REM sleep. Whenever the scientist woke people during REM sleep, they were having vivid dreams. Measurements showed that sleepers' pulses went up quickly during REM sleep. Their breathing, heartbeat, and the blood going to the brain also increased. Far from being a time of rest, REM sleep is a time when the body is hard at work. Scientists still don't know the reason for this. Some believe REM sleep makes learning easier. Babies spend a lot of time in REM sleep. Because of this, some scientists believe that REM sleep helps the brain grow. Others think REM sleep is a time for the brain to empty the day's garbage. One thing all the scientists agree on is that sleep is necessary. Without enough sleep, people make mistakes. Most major car accidents happen during the early morning hours, when people are sleepiest. Options: A REM sleep helps the brain grow. B REM sleep has been watched and recorded by scientists. C REM sleep is a time to empty the day's garbage. D REM sleep is an active time when the body is hard at work. Answer: B REM sleep has been watched and recorded by scientists. Question:

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: The human body is a living machine, and, like all machines, it needs "fuel" to supply it with energy. This is provided by the food we eat. But how much do we need to stay healthy? The energy value of food is usually measured in calories . A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1degC. The number of calories people need per day is different, as the picture shows. Also, the number of calories you use at any one moment normally depends on the activity you are in. For example, you need more calories for standing than for sitting, more for running than for walking, and so on. The energy in food is in the form of three kinds of chemical materials--carbohydrate , protein and fat. Carbohydrate provides 3.8 Cal /gm of the energy, protein 4.0 Cal/gm, and fat 8.8 Cal/gm. Each food contains different amounts of these materials, as the round pictures show. (P= protein C= carbohydrate F=fat) Options: A You need more calories for swimming than for mountain climbing. B A child aged 8 needs the same amount of calories every day as a man over 70 does. C A woman feeding baby needs over 4 times the amount of calories that a baby does.
