Read the following passage and choose the letter A, B, C, or D to indicate the correct word or phrase that best fits each of the numbered blanks. Why is it that many teenagers have the energy to play computer games until late at night but can't find the energy to get out of bed in time for school? According to a new report, today's generation of children are in danger of getting so little sleep that they are putting their mental and physical health at (1)________. Adults can easily survive on seven to eight hours' sleep a night, (2)________ teenagers require nine or ten hours. According to medical experts, one in five youngsters gets anything between two and five hours' sleep a night less than their parents did at their age. This raises serious questions about whether lack of sleep is affecting children's ability to concentrate at school. The connection between sleep deprivation and lapses in memory, impaired reaction time and poor concentration is well established. Research has shown that losing as little as half an hour's sleep a night can have profound (3)_________ on how children perform the next day. A good night's sleep is also crucial for teenagers because it is while they are asleep (4)________ they release a hormone that is essential for their 'growth spurt' (the period during teenage years when the body grows at a rapid rate). It's true that they can, (5)_______ some extent, catch up on sleep at weekends, but that won't help them when they are dropping off to sleep in class on a Friday afternoon. By Tim Falla and Paul A.

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions. Apples are one of the healthiest foods you can eat every day. A traditional American proverb states: "An apple a day keeps the doctor away". But it does not specifically say anything about the best time of day to eat apples. It is generally believed that eating an apple in the morning is good for people, but eating an apple in the evening is like eating poison. There is actually a scientific reason behind this belief. One benefit of apples is that they are a favorable source of fructose, which is a natural form of sugar that gives you a big boost of energy. The energy you get from an apple is longer lasting than that provided by a cup of coffee. Clearly, this is something most people would rather experience in the morning than right before bedtime. Apples also contain high levels of pectin, a kind of dietary fiber. Fiber stimulates bowel movements, which help maintain the health of your digestive system. But if you eat an apple shortly before going to bed, this can cause problems. While you are asleep, your bowels can fill up with gas, making you feel bloated and uncomfortable. You may also wake up several times to use the bathroom, which will prevent you from getting a good night's sleep. Other health benefits of apples come from flavonoids, beta carotene, and B vitamins. Flavonoids are the material that gives flowers and fruits their bright colors, such as the deep red of apples. When eaten, flavonoids can decrease your risk of heart disease, diabetes, and other illnesses. Meanwhile, beta carotene helps prevent cancer, and B vitamins provide the body with a wide variety of important benefits. Apparently, starting your day with an apple really can keep the doctor awayWhich of the following is TRUE about flavonoids?

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions. Each advance in microscopic technique has provided scientists with new perspectives on the function of living organisms and the nature of matter itself. The invention of the visible-light microscope late in the sixteenth century introduced a previously unknown realm of single-celled plants and animals. In the twentieth century, electron microscopes have provided direct views of viruses and minuscule surface structures. Now another type of microscope, one that utilizes X-rays rather than light or electrons, offers a different way of examining tiny details; it should extend human perception still farther into the natural world. The dream of building an X-ray microscope dates to 1895; its development, however, was virtually halted in the 1940's because the development of the electron microscope was progressing rapidly. During the 1940's, electron microscopes routinely achieved resolution better than that possible with a visible-light microscope, while the performance of X-ray microscopes resisted improvement. In recent years, however, interest in X-ray microscopes has revived, largely because of advances such as the development of new sources of X-ray illumination. As a result, the brightness available today is millions of times that of X-ray tubes, which, for most of the century, were the only available sources of soft X-rays. The new X-ray microscopes considerably improve on the resolution provided by optical microscopes. They can also be used to map the distribution of certain chemical elements. Some can form pictures in extremely short times; others hold the promise of special capabilities such as three-dimensional imaging. Unlike conventional electron microscopy, X-ray microscopy enables specimens to be kept in air and in water, which means that biological samples can be studied under conditions similar to their natural state. The illumination used, so-called soft X rays in the wavelength range of twenty to forty angstroms (an angstrom is one ten-billionth of a meter), is also sufficiently penetrating to image intact biological cells in many cases. Because of the wavelength of rays used, soft X-ray microscopes will never match the highest resolution possible with electron microscopes. Rather, their special properties will make possible investigations that will complement those performed with light- and electron-based instrumentsBased on the information in the passage, what can be inferred about X-ray microscopes in the future?
