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: Some businesses and apartment buildings are telling kids to go away. A device called the Mosquitois being used in the United Kingdom, Australia, and New York to keep kids from gathering in big groups and causing trouble. The Mosquitomakes a noise that only kids can hear. About 3000Mosquitounits have been fixed in the United Kingdom. In the United States, managers of an apartment building in New York City recently fixed one to keep noisy kids from taking over the building's entrance-hall. A children's rights agency in England wants the device forbidden. The agency says the device unfairly targets teens. Some also worry that the high sounds could hurt young ears. Fans of the Mosquito say it keeps kids out of trouble and off private property. "Mosquito devices violate the human rights of kids. The use of the devices is targeted at kids because it considers all kids as troublemakers. The devices are also harmful because the noise could hurt kids' hearing. Besides violating our rights, the Mosquitois dangerous. It could hurt the ears and the hearing of teens, babies and animals because they are more sensitive," says California eighth grader Kelly Straky. "It is not right to place the device in a public place. Teenagers have as much right to public places as adults. I listened to theMosquitosound, and it was extremely loud. It hurts not only your ears but also your whole head. It isn't just annoying; it's painful. It should not be allowed." Fans of the Mosquitobelieve that property owners have a right to decide who can be on their property and who cannot.Mosquitodevices are a method of protecting private property and keeping the peace. Property laws are put into place to protect the public. "Yes, I do believe that the rights of teens should be valued, but we must always put ourselves in other people's shoes and see the other side. In this case, doing so allows people to understand the negative effects, such as crime, that loitering can have on an area or a community," said Kayla Hill from New York.
Answer: Lawyers.
Example Output: Who are probably fans of the Mosquito?
