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.
Answer: whether mood affects their learning ability
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: It is the goal of politicians everywhere-----how to win and keep the trust of voters. Now researchers at the University of St Anurew's in Scotland say they may have the answer. They believe politicians could learn a lot from recent advances in science. A growing number of studies have shown that people do judge a book by its cover. Researchers say most of us make quick judgments about a person on the basis of how they look. Studies suggest that people are less likely to trust those with particularly masculine features, such as a square jaw, small eyes or a big nose. " They are considered dominant and less trustworthy," says Ms Cornwell. "It doesn't mean that men who look more masculine are less trustworthy-----it's just our first impression." Those with less masculine features-----larger eyes, a smaller nose and thinner lips are thought to be more trustworthy. The researchers are putting their science to the test at the Royal Society's annual summer exhibition in London. They have copied the faces of Prime Minister Tony Blair, Conservative leader Michael Howard and Liberal Democrat leader Charles Kennedy stressing their dominant and trustworthy features. " We have used a computer program to change the shape of their faces and features. We hope it will help people to understand our work." So should we expect to see them at the exhibition getting tips? "I don't think it's something they will want to try," says Ms Cornwell. "It's not really possible with television. We all know what they look like."
Answer: facial features might give people some wrong impressions

According to the passage, we know that _ .
