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: When Carlos Westez died at the age of 76, a language died, too. Westez, more commonly known as Red Thunder Cloud, was the last speaker of the Native American language, Catawba.www.ks5u.com Anyone who wants to hear various songs of the Catawba tribe can get in touch with the Smithsonian Institution in Washington, D.C., where, back in the 1940s, Red Thunder Cloud recorded a series of songs for future generations. They are all that is left of the Catawba language. The language that people used to speak is gone forever. We are all aware of the damage that modern industry can do to the world's ecology. However, few people are aware of the effect that widely spoken languages have on other languages and ways of life. English has spread all over the world. Chinese, Spanish, Russian, and Hindi have become powerful languages, as well. As these languages become more powerful, their use as tools of business and culture increases. When this happens, hundreds of languages that are spoken by only a few people die out. Scholars believe there are about 6,000 languages around the world, but more than half of them could die out within the next 100 years. Araki is a native language of the island of Vanuatu, located in the Pacific Ocean. It is spoken by only a few older adults, so like Catawba, Araki will soon disappear. Many languages of Ethiopia will have the same fate because each one has only a few speakers. In the Americas,100 languages also are dying out. Red Thunder Cloud was one of the first to recognize the threat of language death and to try to do something about it. He was not actually born into the Catawba tribe, and the language was not his mother tongue. However, he was a frequent visitor to the Catawba reservation in South Carolina, where he learned the language. The songs he sang for the Smithsonian Institution helped to make Native American music popular. Now he is gone, and the language is dead.
Question: Why did Westez record songs for the Smithsonian Institution?
Options: (A) To fight for Native Americans' rights. (B) To deal with the threat of language death. (C) To make Native American music popular. (D) To help young people learn Catawba songs.
