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: 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 .

SOLUTION: Who probably belong to the ant tribe?

PROBLEM: Article: We each have a unique genetic (,) make-up. Every cell of your body has the same set of about 100,000 separate genes made of DNA. These are the instructions for producing a person. Genes decide everything from the colour of your skin to the way your brain works. You have one of several billion combinations of DNA which come from the random mixing of your parents' genes. Except for identical twins , no one has the same combination as another person. You are unique! You are unique in another way too: in the way you are raised and all the experiences you have from before birth to adult life. These experiences influence you, your behaviour and attitudes, and the choices you make. But are genes or life experiences more important in shaping your appearance and personality? Scientists are studying twins to find out. One set of twins occurs every 70 births---some are identical and others are non-identical twins. Identical twins are special because they share exactly the same genes and often the same environment. Non-identical twins are more like ordinary brothers and sisters. Some identical twins have been adopted and brought up in different homes. With identical genes but a different home environment, scientists can study twins to see how much a particular feature depends on the genes we inherit. For example, we know that eye problems, like short-sightedness, are mostly genetic. But resistance to pain is largely dependent on experiences. Genes also influence our eating habits. Identical twins brought up apart often like to eat at the same time of day and feel full after eating the same amount. Non-identical twins in similar circumstances have more varied eating habits. Identical twins are also more likely to follow the same patterns for marriage and divorce than non-identical twins. Scientists are trying to identify the different genes that influence our behaviour. Some people are thrill-seekers and get into risk-taking and adventurous activities. They take up extreme sports like bungee jumping and possibly take drugs. Scientists have discovered a gene which affects _ . We could ask, "Are our lives determined by our genes or our upbringing?" Scientists are learning more all the time, but it is certainly true that both are important in making us who we are.
Answer: To discover what shapes us as individuals.

SOLUTION: Why are scientists studying twins?

PROBLEM: Article: Goats are being hired to do the work of men in a neighborhood just outside of San Diego. The fires that occurred in Hillborough four years ago destroyed thirty homes, most of which have been rebuilt. While the home were rebuilt, the grasses, bushes, and shrubs were re-growing. The area is now so overgrown in brush that it again brings a major danger of fire. The city government asked for bids to remove the brush. The lowest bid they received was $50,000. And that was if the city provided breakfast and lunch for the work crews for the six weeks it would take to clear the overgrown area. The city government said no, offering unlimited coffee and a doughnut a day for each crew member. When that offer was rejected, the city asked for help on its website. A sheepherder in Montana and a goat-herder in San Bernardino read about the city's problem while surfing the web on their laptops. They both offered to do the job for $25,000. The government chose the goat-herder because he lived closer. When told that the city dump was overflowing, the goat-herder said, "No problem. My goats will eat everything in your dump. Except for the automobile engines, of course." So, for another $5,000, the city killed two birds with one stone. If all goes well, they will invite the goat-herder and his "family" back every three years. The goat-herder said he will probably visit San Diego while his goats are in the dump. "I want to go there by plane; I just hope we don't crash. My goats would miss me a lot," he said.
Answer: The overgrowing plants in this area have become a big danger of fire.

SOLUTION:
What faces the city government as a serious problem?
