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: Leaders of the World Health Organization say they are concerned about the air quality and health efiects on citizens during a recent outbreak of heavy pollution in Beijing.Still,they said they were unsure of the exact amount the air pollution takes on any person's body,casting doubts on local reports tying the area's dirty air to particular cases of illness. Speaking at a briefing on Tuesday,the WHO's Western Pacific regional director, Shin Young--Soo,cited reports about poor air quality causing lung cancer in recent weeks. "The WHO is skeptical of the information,"she said."We're cautious of whether the illness is related to air po11ution. We know it has an impact on health,but we don't know how much." The officials didn't cite particular reports.The comments follow a number of articles since late last year connecting some cases of diseases like lung cancer with pollution,.including one in November regarding an 8-year-old girl. The health impact of Beijing's gray skies has been on the minds of many over the past week. Local authorities on Tuesday preserved an orange alert the city's second highest pollution-warning level--and again warned people to stay indoors.Experts widely agree that small particulates known as PM2.5 carry significant short-and long-term health risks,particularly with children.Other studies find a certain link between pollution and shorter life spans. Chinese state media have noted a rise in cancer levels in Beijing,without specifying whether the new cases are the main result of pollution,smoking,other sources or some combination. Bernhard Schwartlander,the organization's China chief,said he is concerned and has been in contact with national authorities."There is no easy solution,"Dr. Schwartlainder said,adding that solving the problem requires managing industry and the economy.WHO leaders advised citizens.to stay indoors and limit exposure to the harmful particulates.When asked if wearing a face mask has any proven efficacy in preventing health effects of air pollution,Dr. Schwartlainder said,"Whatever you do,it's better than nothing."
