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: 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.

PROBLEM: Article: According to body language expert Robert Phipps,the way people sleep at night actually determines a lot about the type of personality they have.Phipps has identified four sleeping positions that affect personality. Phipps found that worriers,those who stress the most,tend to sleep in the fetal position.He found that this is the most common bedtime position,with nearly 58 percent of people sleeping on their side with knees up and head down.The more we curl up ,the more comfort we are seeking,according to Phipps. The second most common position is the log.Sleeping with a straight body,with arms at each side,as if they are standing guard at Buckingham Palace,indicates stubbornness,and these people(the 28 percent who sleep this way)often wake up stiffer than when they went to sleep. "The longer you sleep like this,the more _ your thinking is and you can become inflexible,which means you make things harder for yourself,"according to Phipps. Yearner sleepers are next on the list.About 25 percent of people sleep in this style--on their side with arms stretched out in front,looking as if they are either chasing a dream or perhaps being chased themselves.Yearners are typically their own worst critics,always expecting the best results,explained Phipps.These people often wake up refreshed and eager to face the challenges of the day ahead. Perhaps the most peculiar of sleep styles is the freefaller position.This sleep style makes up 17 percent of the population.They sleep face down with arms stretched out.These people,according to Phipps,feel like they have little control over their life.Not only is this the strangest of sleep styles,but also the least comfortable,and people may wake up feeling tired and have no energy. In conclusion,Phipps has only one more thing to add:"A good night's sleep sets you up for the following day and our sleeping positions can determine how we feel when we wake."
Answer: Your Personality Depends a Lot on How You Sleep at Night

SOLUTION: Which of the following is the best title of the passage?

PROBLEM: Article: In the countries of South and Southeast Asia, the elephant has been an important part of the culture, economy and religion for centuries. And nowhere more so than in Thailand. Unlike its African cousin, the Asian elephant is easily domesticated . The rare so-called white elephants have actually lent the power of royalty to its rulers,and until the 1920s the national flag was a white elephant on a red background. To the early Western visitors, the country's romantic name was" Land of the White Elephant". Today, however, the story is very different. Out of work and out of land, the Thai elephant struggles for survival in a nation that no longer needs it. The elephant has found itself more or less deserted by previous owners who have moved on to a different economic world and a society in the western part. And while the elephant's problems began many years ago, now it has a very low national advantage. How does the national symbol turn into ignored animals? It is a story of worse environment and the changing lives of the Thais themselves. According to Richard Lair, Thailand's expert on the Asian elephant and author of the report Gone Astray, at the turn of the last century, there may well have been as many as 100,000 national elephants in the country. In the north of Thailand alone, it was estimated that more than 20,000 elephants were employed in transport, 1,000 of them alone on the road between the cities of Chiang Mai and Chiang Saen. This was at a time when 90 percent of Thailand was still forest---a habitat that not only supported the animals but also made them necessary to carry goods and people. Nothing ploughs through thick forest better than lots of sure-footed elephants. By 1950 the elephant population had dropped, but still to the number of 13, 397. However, today there are probably no more than 3,800, with another l,350 wandering free in the national parks. But now, Thailand's forest covers only 20 percent of the land. This deforestation is the central point of the elephant's difficult situation, for it has effectively put the animals out of work. This century, as the road network grew, the elephant's role as a beast of burden decreased.
Answer: It is hard to domesticate them.
