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: 136 Crestview Circle Dover, Connecticut January 16, 1995 Gander's Furniture Store Stamford, Connecticut, 09876 Dear Sir, I am writing about your January bill, which I am returning with this letter. I am not going to pay this bill. Last month I bought a table and four chairs for $65.50. They were sent to me on December 18. That night one leg of the table broke while my wife was putting our dinner on it. It fell on one of the chair, and that broke, too. Our $ 2.50 steak landed on the floor, and the dog ate it. I spoke to the salesmen who had sold me the table and the chairs. He told me to write you a letter. I wrote you on December 20, saying that I was not going to pay for the furniture. On December 21 some men came and took it back to the store. Please do something about your records. I do not want to receive another bill for the furniture which I returned. Yours truly Alberts Robbins
