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: Immigration is the act of coming to a foreign country to live. The act of leaving one's country to settle in another is called emigration. Immigrants who flee their country because of persecution, war, or such disasters as famines or epidemics are known as refugees or displaced persons. Most people find it very hard to pull up roots in their native land and move to a strange country. But throughout history, countless millions of people have done so. The heaviest immigration worldwide took place from the early 1800's to the Great Depression, the economic hard times of the 1930's. In that period, about 60 million people moved to a new land. Most came from Europe. More than half immigrated to the United States. Other destinations included Canada, Argentina, Brazil, Australia, New Zealand, and South Africa. Today, the availability of fast, safe, and cheap transportation helps make migration easier. Asia is replacing Europe as the major immigrant-sending area. The United States remains the chief receiving nation. People abandon their homeland and move to another country for various reasons. The main reason for immigration has long been economic opportunity----the desire for better land or a better job. During the 1800's, for example, the rich prairie land of the United States attracted many European farmers. Today, professional people commonly emigrate because of better opportunities elsewhere. Such emigration has sometimes been called brain drain. Many doctors and nurses and numerous engineers and scientists have moved to the United States. Religious persecution has led many people to move to a new land for the freedom to practice their faith. Such immigrants include Jews expelled from England in the 1200's. Wars, revolutions, and political unrest have driven innumerable people to find new homes. In the 1990's alone, millions of refugees fled from warfare in Afghanistan, Iraq, Liberia, Iran, Uganda, Southeastern Asia, and Central America. Some immigrants were brought to a new land against their will. From the 1500's to the 1800's Europeans shipped black Africans to the Western Hemisphere as slaves. The United Kingdom transported prisoners to Australia from the late 1700s to the 1860s to relieve over crowding in British jails. Before that time, the United Kingdom sent prisoners to the American colonies. Immigrants have made enormous contributions to the culture and economy of such nations as Australia, Canada, New Zealand the United States. But their accomplishments have been made with great difficulty. At times, the United States, like many receiving countries, has restricted immigration to maintain a more homogeneous society in which all the people share the same ethnic, geographic, and cultural background. Although some immigration laws have been relaxed, many new comers of different backgrounds still face challenges in gaining acceptance.
