The man traveling in the back of the ambulance which was running at a high speed along the streets of Baltimore that morning in2008 had no business to be alive. By everything that was reasonable, and there were plenty of such things before, he should have been very dead indeed. But he wasn't. As the people in the hospital pointed out after they had examined him, he was only slightly hurt. Yet he had just fallen 150 feet down a hotel lift shaft! Unknown to the man, two things had occurred which were to affect his life that day. On the thirteenth floor of the hotel, somebody had carelessly left the lift gate open. Down in the basement, a pipe had burst and it had flooded from the bottom of the lift shaft to a depth of two feet. Modern lifts have all sorts of fail-safe system to prevent accidents, but this was ancient equipment unreliable, slow, dangerous, and unsuitable material to recycle. The man had plenty of things to occupy his mind that morning. He had overslept. The hotel had forgotten to call him and now he was late for an important business appointment. He dressed quickly, shaved hurriedly, took hold of his briefcase and hurried off down the hotel corridor. Good! The lift gate was open. The lift must be there. He need not press the button and wait while the large, clumsy lift made its way upwards. Without looking or thinking, he stepped out into space, The lift cage was, in fact, one floor above him on the fourteenth. The lift shaft which he had walked was a narrow space of not very fresh air, ending150 feet below in two feet of dirty water. The man fell, making his journey to the ground at a speed he had never dreamed of. Confused patterns, a rush of air, time enough to be afraid, split-second thoughts of death, then crash! Perhaps this gave him the record for some sort of high-diving act. No doubt in future he always looked before he jumped. Certainly he learnt that this was no way to save time. The experts said that those two feet of water had saved his life. Which of the following was NOT the cause of the accident? A) A pipe burst B) The man overslept C) The hotel forgot to call him D) Someone left the lift door open

Skeptics are a strange lot. Some of them refuse to admit the serious threat of human activities to the environment, and they are tired of people who disagree with them. Those people, say skeptics, spread nothing but bad news about the environment. The "eco-guilt" brought on by the discouraging news about our planet gives rise to the popularity of skeptics as people search for more comforting worldviews. Perhaps that explain why a new book by Bjorn Lomborg received so much publicity. That book, The Skeptical Environmentalist, declares that it measures the "real state of the world" as fine. Of course, another explanation is the deep pockets some big businesses with special interests. Indeed, Mr. Lomborg's views are similar to those of some Industry-funded organizations, which start huge activities though the media to confuse the public about issues like global warming. So it was strange to see Mr. Lomborg's book go largely unchallenged in the media though his beliefs were contrary to most scientific opinions. One national newspaper in Canada ran a number of articles and reviews full of words of praise, even with the conclusion that "After Lomborg, the environmental movement will begin to die down." Such one-sided views should have immediately been challenged. But only a different review appeared in Nature, a respected science magazine with specific readership. The review remarked that Mr. Lomborg's "preference for unexamined materials is incredible ". A critical eye is valuable, and the media should present information in such a way that could allow people to make informed decisions. Unfortunately, that is often inaccessible as blocked by the desire to be shocking or to defend some special interests. People might become half-blind before a world partially exhibited by the media. That's a shame, because matters concerning the health of the planet are far too important to be treated lightly. The author mentioned the review in Nature in order to _ . A) voice a different opinion B) find fault with Lomborg's book C) challenge the authority of the media D) point out the value of scientific views.

Of all the animals in the animal kingdom, which one (aside from man) is the cleverest? There are several ways of measuring the intelligence of animals. In one test a scientist sets three same cans on a table. While the animal watches, he puts food under one of the cans. Then he leads the animal away. Some time later, he brings it back to see if it remembers which can has the food. No smelling is allowed; the animal must go directly to the correct can or it fails. This is called a delayed-response test. The idea is to find out how long an animal's memory can keep information. The scientists would try showing the cans to the animal one hour later, or two hours later, or even a full day later. They discovered that chimpanzees and elephants have the best memory, and were able to remember the correct can for at least twenty hours. No other animal is close. Dogs came next, but they only remember for nine hours. To settle the matter, the scientists designed a huge maze and ran the chimps and elephants through it. The maze was very difficult, with many blind paths and dead ends. It took the chimps ten minutes to find their way out. The elephants needed half an hour. Even allowing for the elephants' slower rate of speed, the test shows that chimpanzees are the cleverest animals. From this and other tests, the scientists drew the following conclusion: an animal's intelligence depends on the size of its brain in proportion to the size of its body. The elephant's brain weighs ten pounds. But this is only 1/600th of its 6,000 pounds body. A chimp's brain weighs about one pound, or 1/120th of its total body weight. So in proportion to its body size, the chimp has four times as much brain as the elephant----more brain for less body. The chimp is the champ! The delayed-response test is designed to test an animal's _ . A) eyesight B) intelligence C) learning ability D) memory
