After you hear a question, you must choose the answer from the four choices marked A), B), C) and D). Then mark the corresponding letter on the Answer Sheet with a single line through the center.Passage OneYou can tell the age of a tree by counting its rings. But these records of a trees life really say a lot more. Scientists are using tree rings to learn whats been happening on the suns surface for the last ten thousand years. Each ring represents a year of growth. As the tree grows, it adds a layer to its trunk, taking up chemical elements from the air. By looking at the elements in the rings from a given year, scientists can tell what elements were in the air that year.Dr. Stevenson is analysing one element, carbon-14, in rings from both living and dead trees. Some of the rings go back almost ten thousand years to the end of the Ice Age. When Stevenson followed the carbon-14 trail back in time, he found carbon-14 levels change with the intensity of solar burning. You see the sun has cycles. Sometimes it burns fiercely. At other times its relatively calm. During the suns violent periods it throws off charged particles in fast moving streams, called solar winds. The particles interfere with the formation of carbon-14 on earth when there rises and falls about every four hundred and twenty years. The scientists concluded that solar wind activity must follow the same cycle.Questions 16 to 18 are based on the passage you have just heard.16. Whats the purpose of the scientists in studying tree rings? (C)17. What affects the amount of carbon-14 on earth? (D)18. What do we learn from the passage about solar wind activity? (A)Passage TwoIn addition to exercising regularly, eating a good breakfast is considered by many health experts to be a significant part of a successful way of reduction plan. After a night of fasting the body needs to be replenished with nutrients in order to maintain a high level of energy throughout the day. Several nutritionists suggest that dieters should eat up to one-third of their daily calories at breakfast time. These calories should be in the form of a balanced meal of nutritious food. A balanced meal consists of five key elements: proteins, carbohydrates, fats, vitamins and minerals. People whore dieting need a variety of foods to assure a constant supply of nutrients their bodies need. If a well-balanced diet is not followed, the dieter may become sleepy, nervous, or feel out of sorts. If a poor diet is maintained for a long period of time, the dieters may become vitamin deficient. Vitamin deficiency can cause serious health problems. For this reason, many doctors recommend that everyone, especially those on diets, starts the day with up to one-third of the daily requirement of nutrients in the form of a well-balanced breakfast.Questions 19 to
