Given the task definition, example input & output, solve the new input case.
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.

Output: Researchers did experiments on kids in order to find out _ .
It is clearly mentioned in the article that to the check effect of mood on children is the main purpose of the experiment.

New input case for you: Article: Japanese students work very hard but many are very unhappy. They feel great pressure from their parents to do well in school and in college. Most students are always being told by their parents to study harder so that they can have successful future. Although this may be good advice for those who are very bright, it can have very bad results for many students who are not quick enough at learning. Unfortunately, a number of students actually kill themselves. Others are after comfort in using drugs. Some students, however, do bad things with groups of bad people and turn to crime. Many of them have tried very hard at school but, in spite of all their tries, have failed in certain examinations and have disappointed their parents. Such students feel that they are less important than everyone else they meet and leave school before they finish their study. It is surprising that although most Japanese parents are anxious for their children to do well at school, they do not help them in any way. Many parents feel that they are unable to help their children with their lessons and that it is the teachers' job to help their children. To make matter worse, a lot of parents send their children to special schools called juku-cram schools. These schools are open during the evenings and on weekends, and their only purpose is to prepare students to pass exams; they do not try to educate students in any real sense of the world. Thus comes a shock to realize that almost three quarters of the junior high school students attend these cram schools. Ordinary Japanese schools usually have rules about everything from the length of students' hair to their clothes and things in their school bags. Child psychologists now think that such strict rules often lead to a feeling of being unsafe and being unable to fit into society. They believe that no sense of moral values is developed and that students are given neither guidance nor training in becoming good citizens.

Many Japanese students are unhappy at school because_.
