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: A telescope , called Gaia, is being designed by astronomers in Europe, and it couldn't be more different from Pan-STARRS, which is another telescope being designed. While Pan-STARRS will be looking for asteroids and comets headed for Earth, Gaia will be looking at our entire galaxy . Gaia is designed to draw a map of the Milky Way, our home galaxy. Just as a map of your town gives you a picture of where things are located, Gaia's map of the galaxy will tell astronomers where the stars are. Over five years, Gaia will observe about a billion stars and other objects in our galaxy. Each object will be observed about 70 times. Gaia will be sent into space connected to a rocket. It contains two telescopes, each focused at a different angle . These two telescopes act like Gaia's "eyes". The reason why humans can see things in 3D is that we have two eyes focused on the same object, at slightly different angles. By using two telescopes like eyes, Gaia can produce the first 3D map of the positions of the stars it views. Gaia, which is to be sent into space in 2011, will be a powerful telescope. If you were to use it on Earth, for example, you could stand 600 miles away from your best friends and still get a clear picture of their hair. Gaia is one of more than a dozen telescopes being designed by scientists right now. The next generation of telescopes will reveal new parts of our universe that will seem surprising. The universe, with all its planets, stars and other strange objects, is a puzzle with pieces that we can see by using powerful telescopes.
Answer: 2 .

SOLUTION: How many different angles can Gaia focus at each time?

PROBLEM: Article: Most Americans get what money they have from their work; that is, they earn an income from wages or salaries. The richest Americans, however, get most of their money from what they own -- their stocks, bonds, real estate, and other forms of property, or wealth. Although there are few accurate statistics to go by, wealth in American society appears to be concentrated in very few hands. More than 20 percent of everything that can be privately owned is held by less than one percent of the adult population and more than 75 percent of all wealth is owned by 20 percent of American adults. The plain fact is that most Americans have no wealth at all aside from their homes, automobiles, and a small amount of savings. Income in the United States is not as highly concentrated as wealth. In 1917 the richest 10 percent of American families received 26.1 percent of all income, while the poorest 10 percent received 17 percent, mainly from Social Security and other government payments. The most striking aspect of income distribution is that it has not changed significantly since the end of World War II. Although economic growth has roughly doubled real disposable family income (the money left after taxes and adjusted for inflation) over the last generation, the size of the shares given to the rich and the poor is about the same. By any measure economic inequality is great in the United States. The reality behind these statistics is that a large number of Americans are poor. In 1918, 14 percent of the population was living below the federal government's poverty line, which at that time was an annual income of $ 9 287 for a nonfarm family of two adults and two children. In other words, about one out of seven Americans over 31 million people was officially considered unable to buy the basic necessities of food, clothes, and shelter. The suggested poverty line in 1981 would have been an income of about $11, 200 for a family of four. By this relative definition, about 20 percent of the population or more than 45 million Americans are poor.
Answer: Their house, cars and small amounts of savings.

SOLUTION: What does the majority of the Americans have in terms of wealth?

PROBLEM: Article: Electronic waste, or e-waste, refers to electronic products that are no longer usable. This can include TVs, cell phones and computers and other office electronics, electronic toys and videos machines. Today, the average turnover rate for a computer in the United States is every two years, according to the environmental group, Greenpeace. The group's Dai Yun says e-waste is a global problem. "The electronic industry is one of the fastest growing industries in the world. The high speed of growth in this industry means more and more electronic products are being wasted and thrown away. If no one decides to retrieve the old products and process them properly, the electronic waste will sweep over the earth like the huge wave behind me and pollute the Earth seriously." Greenpeace works out that 20 to 50 million tons of e-waste are produced globally each year. The components in many electronic products contain harmful chemicals that pollute ground water and the environment. At present , the U.S. has no federal law for the disposal of e-waste although a few states have e-waste recycling programs in place, but there is no law. The U.S. exports much of its e-waste to third world countries, such as India and China, where workers took apart computers for valuable parts, hoping to sell them for money. But harmful wastes expert, Dr. Bakul Rao, says that's a dangerous practice. "From now on, the recyclers are not very educated. All they know is they can retrieve copper or gold out of it. So, the easiest way to do that is leach it out in an acid or burn it off to retrieve it. So, that's where they don't know how to deal with it, neither do they have any health systems in place. So, their exposure is more."
Answer: A table

SOLUTION:
Which of the following is most likely not to be a form of e-waste?
