Read the following passage, and mark the letter (A, B, C or D) on your answer sheet to indicate the correct answer to each question. Certainly no creature in the sea is odder than the common sea cucumber. All living creature, especially human beings, have their peculiarities, but everything about the little sea cucumber seems unusual. What else can be said about a bizarre animal that, among other eccentricities, eats mud, feeds almost continuously day and night but can live without eating for long periods, and can be poisonous but is considered supremely edible by gourmets?For some fifty million years, despite all its eccentricities, the sea cucumber has subsisted on its diet of mud. It is adaptable enough to live attached to rocks by its tube feet, under rocks in shallow water, or on the surface of mud flats. Common in cool water on both Atlantic and Pacific shores, it has the ability to suck up mud or sand and digest whatever nutrients are present.Sea cucumbers come in a variety of colors, ranging from black to reddish – brown to sand – color and nearly white. One form even has vivid purple tentacles. Usually the creatures are cucumber – shaped – hence their name – and because they are typically rock inhabitants, this shape, combined with flexibility, enables them to squeeze into crevices where they are safe from predators and ocean currents.Although they have voracious appetites, eating day and night, sea cucumbers have the capacity to become quiescent and live at a low metabolic rate-feeding sparingly or not at all for long periods so that the marine organisms that provide their food have a chance to multiply. If it were not for this faculty, they would devour all the food available in a short time and would probably starve themselves out of existence.But the most spectacular thing about the sea cucumber is the way it defends itself. It major enemies are fish and crabs, when attacked; it squirts all its internal organs into the water. It also casts off attached structures such as tentacles. The sea cucumber will eviscerate and regenerate itself if it is attacked or even touched; it will do the same if surrounding water temperature is too high or if the water becomes too polluted.The word “bizarre” is closest meaning to....

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 from 43 to 50.Sometimes the road to the future leads through the past. Such was the case for Americans Scott and Brennan Olson, who used an old idea to launch a hot new trend in sports: inline roller skating. In 1979, these siblings found a pair of antique roller skates while checking out bargains at a used sporting-goods store. The skates they found had four wheels in a single row instead of the traditional parallel pairs of wheels in front and back. This single row of wheels intrigued the Olsons. They were avid hockey players, and they immediately noticed the similarity between the inline wheels and the long, single blade found on the bottom of ice skates. Could these unusual skates somehow be used to practice hockey off the ice? The Olsons set about trying to modify the design of the antique skates that they had found. First they tested out the antique skates to see how well they worked. From those tests, they tried to come up with ways to improve the old design. One improvement involved using special materials to make the skates stronger and easier to steer. The Olsons also added reliable brakes to their inline skates. In 1980, the Olsons founded a company called Rollerblade to make and sell their “new” invention. Sales skyrocketed, and soon millions of people worldwide were “rollerblading,” as inline skating was mistakenly called. At first, inline skating was recreational. People enjoyed skating in parks and on streets, and some even danced on skates at giant roller discos. Today, inline “group skates” are popular all over the world. In cities such as San Francisco, Paris, and Berlin, as many as 20,000 skaters might meet on a free day and skate together through the streets. Many people see inline skating as a great way to exercise and socialize. By the mid-1990s, inline skating had become more than just a recreational sport. It had developed into several competitive sports. One of the most popular, even today, is aggressive skating. This involves performing tricks and jumping over objects such as boxes, ramps, and rails. Other kinds of competitive skating include speed skating, artistic skating, downhill racing, and skating marathons. So, what about hockey? Well, the Olsons achieved their goal. Inline hockey leagues sprang up almost immediately. Then in 1999, inline hockey joined the lineup at the Pan-American Games. There are rumors that inline skating may even become part of the Summer Olympics somedayThe word "sprang up" in the last paragraph is closest in meaning to____________.

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 from 36 to 42.Are organically grown foods the best food choices? The advantages claimed for such foods over conventionally grown and marketed food products are now being debated. Advocates of organic foods – a term whose meaning varies greatly – frequently proclaim that such products are safer and more nutritious than others.The growing interest of consumers in the safety and nutritional quality of the typical North American diet is a welcome development. However, much of this interest has been sparked by sweeping claims that the food supply is unsafe or inadequate in meeting nutritional needs. Although most of these claims are not supported by scientific evidence, the preponderance of written material advancing such claims makes it difficult for the general public to separate fact from fiction. As a result, claims that eating a diet consisting entirely of organically grown foods prevents or cures disease or provides other benefits to health have become widely publicized and form the basis for folklore. Almost daily the public is besieged by claims for "no-aging" diets, new vitamins, and other wonder foods. There are numerous unsubstantiated reports that natural vitamins are superior to synthetic ones, that fertilized eggs are nutritionally superior to unfertilized eggs, that untreated grains are better than fumigated grains, and the like. One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods. But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods. So there is real cause for concern if consumers, particularly those with limited incomes, distrust the regular food supply and buy only expensive organic foods insteadWhat is the author's attitude toward the claims made by advocates of health foods?
