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: Workers who commute by car, bus or train to the office are more likely to suffer from stress and exhaustion, according to a study. Scientists studied 12,000 employees aged between 18 and 65.They found that those who traveled to work by car or public transport reported higher levels of stress and tiredness compared to active commuters who traveled by foot or bicycle. The negative health of public transport users increased with journey time. It is now expected that the study, from Lund University in Sweden, will encourage further investigation into the health effects of commuting and the best forms of transportation. Researcher Erik Hansson said:"Generally car and public transport users suffered more everyday stress, poorer sleep quality, exhaustion and felt that they struggled with their health compared to the active commuters." According to the Office for National Statistics, the average Briton commutes 54 minutes every day. But now the scientists claim that the advantages of daily travel, such as higher pay or housing conditions, need to be weighed against the negative health effects. Income, family background and environmental factors are other things that need to be considered. It may also have a cost effect on industry. According to a Absence and Workplace Health Survey, the U.K. economy lost 190 million working days to absence last year, with each employee taking an average of 6.5 days off sick, costing employers US$27 billion. Hansson added that findings would help to reconsider the balance between economic needs, health, and the costs of working days lost. However, researchers stress that the findings, published in the journal BMC Public Health, do not prove that commuting causes ill health and further research is needed.
