Teacher: Now, understand the problem? If you are still confused, see the following 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.

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

Now, solve this instance: Article: All Ric O Barry wants is to stop the dolphinkilling, so he is headed to this seaside Japanese town, Taiji.The American activist, who is the star of a new awardwinning documentary that portrays the dolphinkilling here, got an unwelcome reception when he showed up here this week for the start of the annual hunt. His movie, The Cove , directed by National Geographic photographer Louie Psihoyos, was released in the United States a month ago but has not yet to come out in Japan. Scenes in the film, some of which were shot secretly, show fishermen banging on metal poles stuck in the water to create a wall of sound that scares the dolphins-- which have supersensitive sonar --and sends them fleeing into a cove. There, the fishermen sometimes pick a few to be sold for aquarium shows, for as much as $150,000. They kill the others, spearing the animals repeatedly until the water turns red. The meat from one dolphin is worth about 50,000 yen, and is sold at supermarkets across Japan. Greenpeace and other groups have tried to stop the hunt for years.Activists hope The Cove will bring the issue to more people internationally--and eventually in Japan. Already,the Australian town of Broome dropped its 28year sistercity relationship with Taiji last month,partly because of the movie. "Some regions have a tradition of eating dolphin meat," said fisheries official Toshinori Uoya. "Dolphinkilling may be negative for our international image, but it is not something orders can stop." The town government in Taiji--which has made whales and dolphins its trademark--refused to comment about The Cove, or the growing international criticism against dolphinkilling. Many in Taiji take the dolphin hunt for granted as part of everyday life. They are _ about The Cove,seeing themselves as powerless victims of overseas pressure to end a simple and honest way of making a living.
