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.

New input: Article: We like to consider ourselves the superior race, and we are. It's true that we are getting to know more and more, and we actually live in "the information age". Our human vanity makes us believe that we really have to know everything! Surprisingly, we do not have this ability. The question "what is happening in the Bermuda Triangle" is the very proof. Where is the Bermuda Triangle located? The mysterious triangle is believed to be situated between Florida, Bermuda and Puerto Rico, where too many unusual events have happened. On December the 5th1945, five U.S. military planes took off from Florida on a clear day only to disappear over Bermuda. Furthermore, some other disappearances took place; in 1947, an American C54 plane simply disappeared at 100 miles from Bermuda; at 80 miles, a Star Tiger plane disappeared in 1948. Even Columbus had trouble in Bermuda. Some of his journals were about the strange happenings there: "the waters are changing their colors" and "compasses are going wild". Maybe it's why it is called the Devil's triangle or the Atlantic cemetery. Many _ were stated in order to explain the strange events. In spite of these attempts, the mystery of the Bermuda Triangle remains unsolved. Some people get to say that maybe aliens are involved in it. Other imaginative scientists relate the happenings in Bermuda to Einstein's theory, saying that the missing ships and planes are translated to another dimension of space and time and taken into another world. Maybe we will just have to wait to go to Heaven and ask the One who made it. The answer will surely be a satisfying one!
