In this task, you're given an article and an answer. Your task is to generate the fill-in-the-blank question for this answer based on the given article. The blanks are always at the end of the question, and can be filled with more than one word or phrase.
Example: Article: Homework can put you in a badmood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.

Problem: Article: The economy has developed a lot while the Internet is still not fully used in China. A study shows that about two-thirds of typical Chinese Internet users use the computer for news, often entertainment-related, or for online games, music or movies, all can be downloaded for free. Most prefers messages to e-mail, seldom makes online shopping at all. Although they are now depending on the Internet more often than before to communicate with others who have the same professions, hobbies and political interests, online shopping still remains unpopular in China. Three-quarters of users surveyed have never bought anything over the Internet, and only 10 percent do shopping even once a month. Among those who do buy online, most pay for entertainment while others buy phone cards, or computer hardware or software. "Many people don't trust the quality of goods bought online," the researcher said, "If they buy it in a store and don't like it, they can easily bring it back." The survey was done in Beijing, Shanghai, Guangzhou, Chengdu and Changsha. Results do not necessarily project countrywide because Internet use in the countryside is lower than in cities. The study showed that the typical netizens   in the five cities are richer and more highly educated. Males make up two-thirds of the group, and more than 80 percent of users are under 24.Surprisingly, with the ages increase, the percentage decreases. China has more than 200 million people online, however, forty-two percent say they do not use search engines. Others seek entertainment news, as well as information useful for work or study on line. Baidu. com was used by half of those surveyed, compared with a quarter for Google, the leading search engine in the United States.
