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: Effective environmental protection laws and other measures have led to the improvement of water quality in Tai Hu lake in prefix = st1 /JiangsuProvince. The news was announced by officials from the provincial environmental protection bureau, which has just conducted an inspection of the lake area. By the end of September, about 80 per cent of industrial pollutants met required standards and the lake is expected to be cleaner by the end of the year, officials said. According to targets set by the State Environmental Protection Administration, all polluting enterprises must meet set standards by the end of this year or they will be shut down. The Taihu Lake area, which surrounds the cities of Suzhou, Wuxiand Changshou, is one of the most economically developed areas in the country and has long enjoyed a reputation as the "land of fish and rice" However, the quality of water in the lake has been deteriorating at an alarmingly rate in recent years, which has caused concern from the government and local people. Pollution is so high mainly because people do not have enough environmental awareness and have put economic benefits ahead of their surroundings. Economic development in the area has been rapid with hundreds of factories being built. But officials say most of these do not have the anti-pollution equipment or measures they should have. Because of the lack of waste treatment facilities, wasted water and other rubbish from residential areas in nearby towns and villages flow into rivers which are connected to TaihuLake. This also contributed to the lake's pollution. Realizing the seriousness of the situation, the provincial and local governments began to tackle the problem. Experts were invited to offer suggestions and laws and regulations were issued. All newly built factories and enterprises in the lake area were required to install necessary anti-pollution facilities before they can go into operation. Also, some wasted water treatment works will be built in the three cities.
