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.

Now, solve this instance: Article: Fighting racial stereotypes on US campuses often begins by putting students of different ethnic backgrounds together -- under one dormitory roof. Sam Boakye was a freshman at Ohio State University and the only black student on his floor. He was determined to get good grades -- in part to make sure his white roommate had no basis for negative racial views. "You're pushed to do better, to challenge the stereotype that black people are not that smart," he told theNew York Times. Several recent studies have found that having a roommate of a different race can reduce prejudice , diversify friendships and even promote students' academic performance. In a study by Ohio State psychology professor Russell Fazio, black freshmen who came to college with high test scores earned better grades if they had a white roommate--even if the roommate's test scores were low. Another study on student interaction by Duke University suggests that freshmen with roommates of a different race were the most likely to diversify their friendships. "Just having diversity in classrooms doesn't do anything to increase interracial friendships," said Claudia Buchman, an author of the Duke study. "But living together with a different-race roommate does lead to more interracial friendships." There are, however, some problems with such room assignments. Fazio's study found that three times as many randomly assigned interracial roommates weren't living together at the end of the semester, compared with white roommates. Interracial roommates also spent less time together, had fewer joint activities and were less involved with each other's friends than white pairs. As for Boakye, this is not the case. "A lot of white students come without much exposure to diversity, so when their first interaction with a black guy isn't bad, they will make more black friends. I think I made a good impression on my freshman roommate. I saw him this year, and he said, 'Hey dude, you're not the only black friend I have.' That felt good."
