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

Problem: Article: Generations of children who sat through endless lessons of "chalk and talk" in front of a bossy teacher can take some relief. But the "chalk and talk" method helped them achieve better exam results. Modern classroom techniques may make school days a good deal happier, but contentment  is not the road to success in examinations, according to university researchers. Their three-year study, monitoring the progress of 2000 teenagers, tried to measure the influence of the "boredom factor" in 17 selected schools in the north of England. The researchers also found that the old-fashioned approach  of teachers ordering pupils about is still alive and producing results. Their conclusions were welcomed yesterday by educationists who were worried by the shift to less formal lessons. The pupils in the latest study were asked to award teachers marks to measure how frequently they followed or ignored today's fashion for "child-centred" education. A five-point scale was given to spot the teachers who always told them what they should know and what to write down. "It was significant and not anything you would get by chance or accident. Certainly, when you compare the pupil's interest and attitude to school, there is a quite definite and highly significant difference," one of the researchers said. But the rankings were turned upside down when the team of four researchers looked at how the children did in examination. The sort of methods now frowned upon  actually improve the final grades. The researchers said,"There is nothing wrong with old-fashioned, didactic  teaching in the fight place, even if it isn't the flavor at the moment." However, he insisted the best teachers had always mixed the two techniques to match the needs of pupils, although certain examinations forced some to concentrate more on dictation and learning by rote .
