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: Recently Chinese society has seen a flowering of a new vocabulary. Perhaps the most interesting has been the division of people into tribes (zu in Chinese). The pains of the yi zu, or the ant tribe, have been well-known --- recent graduates from outside the main cities who move to urban areas, live cheaply and work hard, often in low-paid jobs. Perhaps less well-known are the ken lao zu, the bite-the-old tribe, those between 25 and 35 who are out of work, still at home and depending completely on Mum and Dad. Many of the tribes, inevitably , are made up of people looking for love. There is the jia wan zu, the marry-the-bowl tribe. These are young women searching for the most stable husbands, the ones who hold government jobs. The shan hun zu, or lightening-marriage tribe, marry fast and sometimes separate faster. They should not be confused with the yin hun zu, the hidden-marriage tribe. These are women in their 20s who hide the fact that they are married. And if you can only afford a postage stamp of an apartment, you're probably a member of the wo ju zu, the snail-house tribe. You can belong to more than one tribe. Most members of the ant tribe also belong to the ben ben zu, the rush-rush tribe, to which, in fact, most urban Chinese belong. All that rushing around can create a lot of anger, leading to the nie nie zu, the crush-crush tribe, so named because they go into supermarkets and take out their anger by standing in the passages crushing packets of instant noodles. Another famous one is the yue guang zu, or moonlight tribe, so named because the Chinese characters for "moonlight" sound the same as the phrase "spend all your monthly salary". Their parents save every coin, but life for these young people is just to spend, spend and spend.
Answer: Graduates from the countryside .
Example Output: Who probably belong to the ant tribe?

Example Input: Article: Nanjing-style paper cutting is an important part of Chinese paper cutting. It is known for its different designs, simplistic but graceful shapes, finely cut lines and unique skills. Zhang Fanglin is a leading figure in the Nanjing-style paper cutting. Zhang was born in a paper-cutting family. He is the fourth generation to continue the family's paper-cutting skills. Taught by his father, he began to learn paper cutting in his childhood. In 1963 when he was only 14 years old, he started his artistic career in a local folk handicraft factory. Over the past decades, Zhang has created many works and developed excellent skills. In 1985, Zhang was admitted into Nanjing Municipal Fine Arts Company, creating and designing paper cuts. Throughout his artistic career, Zhang has absorbed characteristics and elements of various styles of paper cutting and created a large number of creative paper-cutting works. Thanks to his great contributions, he won many national prizes and was awarded the title of "National Master Artist in Handicraft Art". As a leading figure, Zhang Fanglin has been invited to more than 30 countries and regions around the world, showcasing his paper-cutting skills. In the 2010 Shanghai World Expo, Zhang showcased his new creations of gold foil-embedded paper cutting works.
Answer: A paper cutting artist.
Example Output: What is the passage mainly about?

Example Input: Article: A huge cloud of dust rose and an overpass disappeared. This was the scene in Zhuzhou,Hunan Province on May 17.Nine people were killed and 16 injured. Things were similar last year in the Sichuan earthquake. Thousands of people were buried in the ruins and lost their lives. What if we could have warned them? People are always _ to find a way of preventing buildings' collapse. Better materials and technology help,but they are not a solution. Just like humans,a building has its own life cycle from "birth" to "death".If we know when a building is going to collapse,we can repair it in advance or get out of it before it falls. Now,scientists at the University of Illinois have developed a material that turns red before it breaks. The invention could be used in things like climbing ropes or bridge supports. The research was led by Nancy Sottos,a professor at the university's Beckman Institute,and Douglas Davis,a graduate research assistant. The secret behind the colorchanging material is a type of molecule .A molecule is a group of atoms held together by chemical bonds. Imagine you and your friends standing in a circle,holding hands. Each person stands for one atom,your hands represent the bonds,and the entire circle represents a molecule. If one person lets go of his or her hands,the molecule changes color. The research team put the molecule into a soft material. When the researchers stretched the material,it turned bright red for a few seconds before it broke into two pieces. When they repeatedly stretched and relaxed the material,without breaking it,it only turned a little red. The major problem is that light can get rid of the red color. When the team shone bright light on the molecule,the broken bond was fixed,and the color disappeared. If the bright light keeps the red color from appearing,the material's warning system will be useless. Scientists still have a lot of work to do before the colorchanging molecules can be used outside the lab.
Answer: A way of preventing building from collapsing.
