TASK DEFINITION: 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.
PROBLEM: Article: The "Occupy Wall Street" movement gained more support on Wednesday as unions and students joined in. With the protests developing from a group of young people's camping out near the New York Stock Exchange on September 17 to large-scale movements across the country and around the world, people can't help asking: What has led to "Occupy Wall Street?" Three years after the severe economic crisis, the U.S. economy now is stuck again. Protesters are not satisfied with the present economic situation since unemployment rate is above 9 percent and economic growth has slowed. The housing market is still struggling for a recovery three years after the bubble burst. People are losing their houses even after they have paid a large amount of mortgage . It is getting difficult for young people to find jobs. People feared that a similar crisis like the one in 2008 may be already on its way. It is Wall Street that possessed the most riches. It is Wall Street greed that, at least partly, led to the financial crisis in 2008. It was Wall Street's "fat cats" who take taxpayers' aid money as their own big bonus . With the growing economic crisis around the world, people realize that Wall Street is responsible for it. So they try to target people who created the crisis. The majority of the protesters are young people under 30. Many of them are unemployed. Some are students with mountains of loans . Some are hard-working people about to lose their houses even if they have paid a large amount of mortgage. They are complaining that the hard-working middle class is getting poor, yet Wall Street stays wealthy. William Cohan, author ofMoney and Power: How Goldman Sachs Came to Rule the world, wrote recently that Wall Street not only learned nothing from the 2008 crisis, they are also trying to kill all reforms that might "break this dangerous cycle in which bankers get very rich while the rest of working people suffer from their mistakes."
Answer: The cause of the "Occupy Wall Street" movement.

SOLUTION: . What is the main idea of the passage?

PROBLEM: Article: An astronomer is making a case for launching pop singer Justin Bieber into suborbital space aboard a private rocket ship. The idea is not to rid the world of the Canadian teenager -- he would come back down to Earth eventually, after all -- but rather to help jump-start the emerging suborbital spaceflight industry. It would generate a lot of public interest, which would help commercial spaceflight pick up some much-needed momentum, said Seth Shostak, senior astronomer at the Search for Extraterrestrial Intelligence (SETI) Institute in Mountain View, California. "If there's more interest, there are more customers. If there are more customers, there's more technical development. It's a positive feedback loop, and obviously that's good." Such missions would return to Earth without completing a full lap around the planet. Instead, the flights would hit the edge of space about 62 miles (100 kilometers) above Earth, experience a few minutes of weightlessness, then re-enter the atmosphere and land back at a spaceport. None of these firms are ready to fly customers yet, but some are getting close. For instance, Virgin Galactic hopes to begin powered test flights of its SpaceShipTwo vehicle later this year, with commercial operations perhaps beginning in 2013 or 2014. It is SpaceShipTwo that reportedly grabbed the attention of Beyonce and Jay-Z. Virgin Galactic has collected deposits from nearly 500 customers willing to pay $200,000 for a ride aboard SpaceShipTwo, and both Virgin and XCOR have inked deals to fly scientists and their experiments on research flights. So a suborbital market already exists -- but Shostak is thinking about ways to make it grow. A celebrity launch isn't Shostak's only idea. Suborbital firms should also promote their activities aggressively via social media, Shostak said, and they should make sure their spaceships are bristling with cameras both inside and out, to give the public dramatic views of every mission. Some observers view commercial suborbital spaceflight as a potentially transformative industry, saying it could serve as a stepping stone to the exploration and exploitation of space on an unprecedented scale. While the industry's success is far from assured, Shostak offered some reason for optimism: The American public remains keen on space.
Answer: To arouse the American public's interest.

SOLUTION: Why may Justin Bieber be sent into suborbital space?

PROBLEM: Article: The human body is designed to move. But modern lifestyles and office jobs rarely give us the chance to move around. As we know. we're while we're eating; we sit in the car and we sit while we watch TV. And many of us sit for many hours at work. New research shows that sitting less than three hours a day might extend your life by two years. Peter Katzmarzyk,a scientist at the University of Louisiana in the southern United States,says that sitting is ubiquitous in our lives,meaning it is something we do all the time,everywhere. However,Mr. Katzmarzyk says that does not mean you can sit for the rest of your waking hours. He also says you may exercise often,"We can't throw away physical activity. It's extremely important. We have 60 years of research showing us that. " Mr. Katzmarzyk and his coi leagues are part of a new generation of researchers studying how sitting all day affects length of life. "Studies that have assessed the relationship between sitting and mortality or television viewing and mortality are very rare. There's only been a few of them,actually five or six now,in the last four or five years. "They found that cutting television time to less than two hours a day could add one-point four years to life. Luckily,change is already coming to some offices,especially in the design of desks. A "standing desk"lets people stand while they work. Another new design is called the "treadmill desk. " A treadmill is an exercise machine that lets you walk in one place. Even some U. S. schools are beginning to experiment with desks that are part bicycle to keep children moving. That's one of the strategies that many companies are using now. Mr. Katzmarzyk also says studying this problem has inspired his team to make a few changes in their own lives.
Answer: Exercise is important and don't sit too long.
