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: Suppose that we lined up our roughly 14 million United States businesses in order of size, starting with the smallest, along an imaginary road from San Francisco to New York. There will be 4,500 businesses to the mile, or a little less than one per foot. Suppose further that we planted a flag each business. The height of the flag pole represents the yearly volume of sales , each $ 10, 000 in sales in shown by one foot of pole. The line of flagpoles is a very interesting sight. From San Francisco to about Reno, it is almost unnoticeable, a row of poles about a foot high. From Reno eastward the poles increase in height until, near Columbus, Ohio - about four - fifths of the way across the nation - flags fly about 10 feet in the air. But as we approach the eastern terminus , the poles suddenly begin to mount . There are about 300, 000 firms in the country with sales over $ 500, 000. These firms take up the last 75 miles of the 3,000 - mile road. There are 200, 000 firms with sales over $ 1 million. They take up the last 50 miles. Then there are 1, 000 firms with sales of $ 50, 000, 000 or more. They take up the last quarter of a mile before the city limits, flags flying at cloud height, 5 , 000 feet up . At the very gate of New York, on the last 100 feet of the last mile , we find the 100 largest industrial firms . They have sales of at least $ 1.5 billion, so that their flags are already miles high. Along the last 10 feet of road , there are 10 largest companies . Their sales are roughly $ 10 billion and up : their flags fly 190 miles in the air , almost in the stratosphere .
Answer: To tell us how the United States businesses are arranged.

Example Input: Article: Polar bears are born in dens on land and their mother stays with them for the whole winter without eating anything. The mother and the babies come out from the dens around March, _ from a long winter and must immediately go hunting to find food to stay alive. Now, the only hunting they know is to catch seals from floating ice in the open ocean. In March, polar bear mothers and babies have to swim from the land in Spitsbergen to the edge of the polar ice cap. Normally this is a short swim, since in March the polar ice cap is very close to the land, and the polar bears, and even the babies, are good swimmers. However, last year we saw that the polar ice cap had become smaller in size due to global warming. Swimming hundreds of miles, especially when they are hungry and have babies following them, is really hard, and many bears are dying because of starvation. The polar bear population in the Spitsbergen area was once threatened by hunters. In the 1970s, a ban on hunting was imposed and the polar bear population has been steadily increasing from just a few hundred to about 2,000 to 3,000. This was a great success story. However, now, because of global warming, the population is again in danger. If we do not stop making so much carbon dioxide, we will lose these beautiful animals forever. The polar bears are just one example of animals that have become endangered because of man's appetite for energy obtained by burning fossil fuels. All life on earth could be in danger unless we change our ways. What can we do? To reduce the amount of carbon dioxide in the air we must save and make energy without burning coal and oil. Instead, we can use the sun or the wind to generate electricity. We must also cut down on needless driving and turn off things that use electricity when we are not using them. In addition, we have to stop cutting down forests and start planting more trees.
Answer: To catch seals for food.
Example Output: Why do the bears swim to the edge of the polar ice cap?

Example Input: Article: More than 40 years ago, John Williams gave away all of his belongings and went off to the mountains to live the way people lived 100 years ago. For food he traps wild animals, fishes in the rivers, and plants whatever he can. John lives in a cabin he made by hand, out of trees he chopped down with an ax. Though he has no s he knows of, he does have a deer he raised from a fawn. The deer lives in the house in the winter and goes with John when he goes into the forest for food. Nobody lives within fifty miles of his cabin in the mountains and John has not been out of the mountains during the entire forty years. One day last year I hiked in to see how John lives. It was like going back in time. There were no roads, no stores, no noise, no pollution, not even a post office. Most notable of all, there were no people and that's just the way John Williams wants to keep his part of the world--without people. But there is a paradox in his story. John is an educated man. He has books and nobody knows how he got them. Mostly he reads about his world, the forest, the animals, the plants, and the mountains. He has seen airplanes flying overhead but does not want to know about them. For him, electricity is lightning, not light bulbs, refrigerators, televisions, or washing machines. John Williams is 85 years old and had not had a sick day in his life. He attributes his long life to the fact that it has nothing to do with people and in order that he might enjoy many more years of health, happiness, and solitude, I will not tell you where his kingdom lies. There is no room there for you or me.
Answer: John Williams himself.
Example Output:
Who lives in John Williams' house?
