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: For a long time, the traditional method of identifying liars was to watch their body language, including facial expressions. What if the person appears to be nervous? Is the person unable to look me in the eye? Is he or she look around the room? What about other nervous movements, such as fidgeting or shifting from side to side? Many people--from parents to police officers and airport security personnel--depend on this method. But does a person's body and face reveal the truth? Not according to a new study. Talking, it seems, is the best way to smoke out a liar. That is what researchers in the United Kingdom found out recently. Their investigation took place at one place where lying can get you into big trouble--an airport. The researchers asked volunteers to pretend they were real passengers and then lie to airport security agents. Some of the agents used spoke conversation-based methods to question these make-believe passengers. Others depended instead on the person's body language, like lack of eye contact and showing signs of nervousness. The agents talking with the passengers were 20 times more likely to catch the liars. The study found that these conversation-based techniques can help you recognize when a person is lying to you. Like many methods, this conversation method has a name. It is called Controlled Cognitive Engagement or CCE, for short. The British government partly financed this study. The American Psychological (APA) published the findings. Body language cannot be trusted. Using body language and facial expressions to catch someone in a lie is really hard. And it only works, seemingly, by chance. Thomas Ormerod is the head of the School of Psychology at the University of Sussex in England. On the APA website, he reported that the "suspicious-signs method"--or using body language--"almost completely fails" in finding lies.
Answer: Communicate with researchers by talking.
Example Output: What should volunteers in the investigation do?

Example Input: Article: It's a too long story -- 17 months to be exact -- with an ending that's short and sweet. Ruthie has, finally and happily, been reunited with her family. The story goes back to October, 2005. Ruthie, 8 months old, was sitting on the back seat of the family car when her owner walked hurriedly into a Long Island store. When Nancy Noel returned a few minutes later, Ruthie was nowhere in sight. Nancy Noel and her husband, Lincoln Werden, got in touch with Nassau County police, put up flyers around their Manhasset neighborhood. But no sightings of Ruthie were reported. Until last week, that is, someone sent Ruthie to a Manhattan shelter after finding her walking slowly around the Bronx -- 25 miles from where she was taken on that fateful October day. And then, shelter workers searched Ruthie for a possible microchip -- she had one fixed under her skin. It showed her family's name and address. Ruthie was immediately reunited with Nancy Noel and her daughter, Sara Werden. "We never thought we would see her again," said Sara Werden. "We were just amazed." She's no longer the tiny pup they last saw. In fact, Ruthie gained 10 pounds during her months away from home. She's on a diet now, and has already lost one and a half pounds. Ruthie also has a new friend to play with. The family had got another dog, named Holly, after losing the hope of ever finding their beloved Ruthie.
Answer: In March 2007.
Example Output:
According to the passage, when did Ruthie get together with her family?
