In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.

Example Input: Article: Chinese scientists have found a new way to use cells found in human urine that could aid in the treatment of a range of nerve disorders.That is a new technique for reprogramming cells in human urine into nerve progenitor cells that can grow into multi-functional nerve and brain cells. The technique is expected to be used in the study and treatment of nerve disorders such as Parkinson's disease, Alzheimer's disease and other nerve disorders. Pei Duanqing, a professor at Guangzhou Institutes of Biomedicine and Health, Chinese Academy of Sciences, said his research team has combined an episomal system to deliver reprogramming factors with a chemically defined culture medium to reprogram kidney epithelial cells in urine into NPCs. These NPCs, normally only found in the human brain, were later proven to be transgene-free and self-renewing, he said. "These nerve and brain cells can survive for up to one month when transplanted into the brain of a newborn rat," said Pei. "My team is working hard to understand why our experimental condition allowed the urine cells to become NPCs, because we want to improve the technique and make it more efficient". Scientists have long searched to treat and study neural disorders by obtaining and transplanting neural stem cells. However, the previous method of getting and using cells from either fetal or adult human tissue remains challenging due to ethical concerns and immune system rejections, he said. Pei hopes the discovery will be used to generate NPCs from patients with nerve disorders such as Parkinson's disease. "These NPCs from patients may help us discover new drugs for these diseases." "It is a remarkable advance in the stem cell field. The results and methods obtained from this study will be of great value and significance to the field, " said Fred Gage,a professor with the Salk Institute for Biological Studies.
Answer: Chinese scientists succeeded in making NPCs from human urine.
Example Output: What is the passage mainly about?

Example Input: Article: John Milton, the most learned poet, is the greatest writer of the seventeenth century and one of the giants of English literature as a whole. He was greatly influenced by two historical movements of Renaissance and Reformation. Like Spenser and Shakespeare, he was also one of the Renaissance giants not only in England but also in the whole world. Almost all later poets in English literature respected Milton highly. Milton _ over his age as Shakespeare towers over the Elizabethan age, and as Chaucer towers over the medieval period. John Milton was born in London in 1608. His education began at St. Paul's School, where he was very hard-working, where he showed wonderful gifts as a student of languages mastering Greek, Latin, Hebrew and many modem European languages. He also received very good home education under the influence of his father who was a Puritan and a lover of music and literature. He attended Christ's College, Cambridge University, where he was very popular because of his handsomeness and talent, where he explained the true aim of knowledge as making the spirit of man "reach out far and wide, until it fills the whole world and the space far beyond with the expansion of its greatness", where he graduated with B.A. in 1962 and M. A. in 1963.
Answer: Spenser, Shakespeare and John Milton had the friendly relationship between them.
Example Output: According to the passage, which of the following is NOT true?

Example Input: Article: Global warming happens when greenhouse gases trap heat and light from the sun in the earth's atmosphere, which increases the temperature. This is like when heat is trapped in a car. On a hot day, the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can get into the car, by going through the windows,but it can't get back out. This is what the greenhouse effect does to the earth .The heat and light can get through the atmosphere, but it can't get out As a result,the temperature rises. Sometimes the temperature can change in a way that helps us. The greenhouse effect makes the earth appropriate for people to live on Without _ ,the earth would be freezing,or it would be burning hot. It would be freezing at night because we would not get the sun's heat and light .During the day, especially during the summer, it would be burning because the sun would be up with no atmosphere to filter it,so people,plants,and animals would be exposed to all the light and heat. Although the greenhouse effect makes the earth able to have people living on it,if there gets to be too many gases,the each can get unusually warmer, and many plants,animals.and people will die. Plants would die because they would not be able to take the heat .This would cause us to have less food to eat, and it would also limit the food that animals have. With less food for the animals that we need to survive we would even have less food. Gradually, people,plants,and animals would all die of hunger. People are doing many things to try to stop global warming .One thing is carpooling--driving with someone to a place that you are both going to. Another thing is being more careful about leaving electrical devices turned on. Now, more people are even riding buses or bikes to lower the amount of greenhouse gases in the air .Although adults do many things to help stop global warming, kids call do just as much.
Answer: It prevents all the light from the sun shining on the earth.
Example Output:
What is the effect of atmosphere?
