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: 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?

Example Input: Article: The Olympic Games are seen as the greatest test of an athlete's ability and are supposed to celebrate the spirit of fair play. But in fact, sportsmen have been using drugs to cheat their way to victory since the Games first began. In the early years, athletes ate mushrooms and plant seeds to improve their performance. Nowadays, this kind of cheating has a name doping . Just last month, Britain's top sprinter Dwain Chambers and several American athletes tested positive for the drug THG. Until a coach secretly gave a sample of THG to scientists, no one knew how ho test for it. "We're like cops chasing criminals--athletes are always adapting and looking for areas we haven't investigated," said Jacquew de Ceaurriz, a French anti-doping expert. Since the first drugs test was carried out at the 1968 Olympics in Mexico City, many cheats have been caught out. The most famous case in history is that of Canadian sprinter Ben Johnson. He broke the 100 meters world record in winning gold at the 1988 Seoul Olympics. But days later, he tested positive for drug use, lost his gold medal and was banned from the sport. Five years later, he returned to action--only to be found positive again and banned forever. China has also had problems with drug cheats. At the 1994 Asian Games, 11 Chinese athletes--seven of them swimmers--tested positive for banned drugs. Sports organizations promised that cheating on this scale would not happen again. Experts are also worried that doping can damage a person's health. It is believed to increase the risk of liver and kidney diseases, and women may experience reproductive problems. As long as they can stay ahead of the scientists, it is unlikely the cheats will stop. But experts say there is a limit to what can be achieved and that athletes will not be able to change their bodies using gene technology. "For the moment, genetic doping does not exist," said de Ceaurriz. "Even in 10 or 15 years it will not be done easily--the scientific community will not let it happen."
Answer: Eating plant seeds.
Example Output: Which of the following is not the way that some athletes cheat to their better sports achievements?

Example Input: Article: NEW YORK-- The band Atomic Tom has scored an Internet hit with its self-created video to the song Take Me Out. In the video, the band members ride a New York City subway while performing entirely on iPhones, with applications linked with mini-battery powered broadcasters for each instrument. Singer Luck White says the production was a top-secret operation. "We didn't tell anyone about this. It was completely top-secret from our family, from our friends, from management, from everybody. So the first time that people saw this video was last Friday when we put it on YouTube,"explained White. It has been watched by more than 2 million on YouTube since debuting last week. "All I've wanted to do for the past few days is just stare at the YouTube page and keep refreshing it to see how far it will go, " said Espiritu, the lead guitarist of the band. "The Internet changed everything,"Espiritu said. "It's kind of an exciting time because it forces everyone to adjust and be creative and find new ways to get your name out there." The idea for the video came from Espiritu's 24-year-old brother Benjamin, who's hoping to go to film school. " I've seen a lot of these music applications, and they're kind of fascinating to me,"Benjamin Espiritu said. " I thought: 'What would happen if iPhones kind of took over the world? If there could actually be a band that played straight through with iPhones, what would that look like?'" So they shot the video --with iPhones also serving as video cameras. The band also tried Union Square but were stopped during playing because they didn't have a permit. " _ ,"Espiritu said. "We've seen the jump." Their album has been in the top 10albums on iTunes. Will their fans start cheering for iPhone-only performances? "We've gotten the most exposure and teh most fans that we've ever gotten through this, so I wouldn't be surprised if fans are going to want to see that.: Espritu said.
