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: When tea was first brought to England between 1652 and 1654, it was so expensive that only the rich could buy it. It was said that an old couple had some sent to them as a great treat. But they did not know how it ought to be used. Eventually they boiled the leaves, put some of them on a piece of bacon for dinner, ate the leaves, and threw the tea soup away. However, tea quickly proved popular enough to replace ale as the national drink of England after King Charles II and his Portuguese wife began to follow this foreign tea tradition. Before the introduction of tea into Britain, the English had two main meals -- breakfast and dinner. Breakfast was ale, bread and beef. Dinner was a long, massive meal at the end of the day. It was no wonder that Anna, the Duchess of Bedford (1788 -- 1861) experienced a _ in the late afternoon. So she invited friends to join her for an additional afternoon meal at five o'clock in her castle. The menu centered around small cakes, bread and butter sandwiches, and, of course, tea. This summer practice proved so popular that the Duchess continued it when she returned to London, sending cards to her friends asking them to join her for "tea and a walking the fields". The practice of inviting friends to come for tea in the afternoon was quickly picked up by other social hostesses. A common pattern of service soon came into practice. The first pot of tea was made in the kitchen and carried to the lady of the house who waited with her invited guests, surrounded by fine porcelain from China. The first pot was warmed by the hostess from a second pot (usually silver) that was kept heated over a small flame. Food and tea was then passed among the guests, the main purpose of the visiting being conversation.
