input question: Write a multi-choice question for the following article, with the given choices and answer: Article: After a day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day. There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other. Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs your eyeballs begin to move quickly (although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement. If you have trouble falling asleep, some people recommend breathing very slowly and very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion that counting sheep will put you to sleep. Options: A Sleep. B Good Health C Dreams D Work and Rest Answer: A Sleep. Question:???

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Our boat floated on between walls of forest. It was too thick for us to get a view of the land we were passing through, though we knew from the map that our river must be passing through chains of hills from time to time. Nowhere did we find a place where we could have landed: although the jungle did not actually spread right down into the river, banks of soft mud prevented us from going ashore. In any case, what would we have gained by landing? The country was full of snakes and other dangerous creatures and the jungle was so thick that one would be able to advance slowly, cutting one's way with knives the whole way. So we stayed in the boat, hoping that when we reached the sea, a friendly fisherman would pick us up and take us to civilization. As for water, there was a choice. We could drink the muddy river water, or die of thirst. We drank the water. Men who have just escaped from what appeared to be certain death lost all worries about such small things as diseases caused by dirty water. In fact, none of us suffered from any illness as a result. One day we passed another village, but fortunately nobody saw us. We did not wish to risk being taken prisoners a second time: we might not be so lucky as to escape in a stolen boat again. Options: A they were in an uninhabited area B they were on a journey home happily C the country was a civilized society D the country was a tropical jungle coutry Answer: D the country was a tropical jungle coutry Question:???
output answer: From the passage, we can learn that.
