Problem: 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.

Problem: Article: My nephew, Adam, turned 19 on Monday. He's a good kid and makes the whole family laugh. He wears his baseball cap backward, his shorts baggy and his T-shirts loose. In short, I hate the way he looks. To me, it seems as if everything is about to fall off at any moment. He makes me nervous. But he's still a teenager. I think that's the way he's supposed to look. Cooler than cool. I was on the Harvard campus recently and was surprised how almost everyone looked like Adam, just as they did on the Georgetown campus the week before with baggy shorts far below the knees. It's a uniform, of course, just as there was a uniform when I went to college. Fashion is a changeable thing. _ has made fools of us all over the years. In my college years, everyone wore frayed bell-bottoms, tie-dye shirts and hair to the shoulders. But I predict the "uniform" that's likely to cause the most shame for its wearers 30 years from now will be the exposed-tummy look brought to us by Britney Spears. I'll admit. Britney's exposed-mid-waist looks pretty good in those short jeans. Just a piece of skin. Firm, flat, brown. Unfortunately, the look has been picked up by young women from Malibu to Maine, young women who do not have Britney Spears' firm, flat, brown skin. As my mother has asked a thousand times: Don't these girls have mirrors?
