Q: 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
A: Researchers did experiments on kids in order to find out _ .
Rationale: It is clearly mentioned in the article that to the check effect of mood on children is the main purpose of the experiment.
Q: Article: The city can seem a cold, mean place. In the middle of so many people hurrying about their own business, a person can feel alone among the millions of others. There is a popular view that in cities, strangers are less likely to help an elderly person cross a street or call the police when they see a bike being stolen. Recently, a New Yorker named Casey Neistat did an experiment. He chained up his bike in several public places, then "stole" it in a number of obvious ways, such as using a hacksaw . He filmed everything to see whether other New Yorkers would try to stop a shameless bike theft. The result? People just walked on by. Is this evidence of an immoral, selfish urban society? Not necessarily. According to another recent study, the way city people mind their own business is about other factors besides morality . This is called the Bystander Effect, the theory that city people do not react because of the urban enviromnent they live in. Psychologist Dr. Harold explained why people did not involve themselves in Neistat's bike theft experiment with the Bystander Effect. First, people who live in cities are surrounded by so much activity that they stop noticing what is going on around them. Second, they are less easy to surprise and assume every activity has a logical explanation. "The third is that people notice it, but they don't know what to do," he continued. "And the fourth is fear -- they know they should do something, but they're afraid to challenge someone with a hacksaw." A lack of concern is only a small reason why people don't take action, concludes Dr. Harold. Despite the results of Neistat's experiment, there is also evidence of a sense of team spirit that connects people in cities. All it takes is a funny joke or a shared interest to start a conversation with someone at a bus stop. When city folk are in trouble, they come together for support -- famously in New York on City society is different, but that doesn't mean it's cold or mean -- it just means it's busy!
