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.

[Q]: 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.

[Q]: Article: What if you arrived home to find a delicious hot meal waiting for you,prepared by your very own kitchen robot? It might sound like science fiction,but professors at the university of Tokyo have taken the first steps toward making that scenario a reality.The team recently introduced a humanoid kitchen robot that can pour tea and other drinks into cups and serve them to guests.When teatime is over,the robot can also wash the dishes and put them away. In California,another interesting kitchen robot has been developed.Called the Readybot,it can pick up objects and either store them in cabinets or put them in the trash.It also carries a separate floor-cleaning robot that can operate by itself.Unlike the Japanese robot,Readybot is not humanoid.Instead,it looks more like a large box with arms and wheels. Readybot was created by engineers and designers who established a club called the Readybot Challenge.They believe that in the future millions of robots will be needed in homes to perform ordinary household tasks.Readybot is just the first step in their plan to create a robot that can tackle jobs not only in kitchens but in other rooms of homes and in offices as well. Clearly there are technological hurdles to overcome before robots can cook a complete dinner,and there are also many safety concerns.Not everyone(especially parents)would be comfortable with the idea of robots in their house,manipulating hot pans and sharp knives.The European Commission recently funded a project to study these concerns.
Answer: it looks more like a person than Readybot does.
[A]: What does the writer imply about the Japanese robot?

[Q]: Article: On March 19, 2013, Malala Yousafzai, a 15-year-old Pakistani student and women's-education activist , returned to the classroom for the first time since being attacked by a member of the Taliban on October 9, 2012. Malala was shot on her way home from school in Mingora, Pakistan. The Taliban said that they did the attack. The group said the attack should be a warning to others. Malala was targeted because she expresses her opinion publicly about girls' rights to education. After a long period of recovery, Malala is starting as a ninth-year student at Edgbaston High School. It is the oldest independent girl's school in Birmingham, England. Though she has no specific plans to return to Pakistan, Malala still speaks out as a voice for change in her country, and everywhere. "I'm excited that today I have realized my dream of going back to school. I want all girls in the world to have this kind of chance," Malala said in a statement . Malala has been an Internet blogger since she was 11 years old.
