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 following questions. Most desert animals will drink water if confronted with it, but many of them never have any opportunity. All living things must have water, or they will expire. The herbivores find it in desert plants. The carnivores slake their thirst with the flesh and blood of living prey. One of the most remarkable adjustments, however, has been made by the tiny kangaroo rat, who not only lives without drinking but subsists on a diet of dry seeds containing about 5% free water. Like other animals, he has the ability to manufacture water in his body by a metabolic conversion of carbohydrates. But he is notable for the parsimony with which he conserves his small supply by every possible means, expending only minuscule amounts in his excreta and through evaporation from his respiratory tract. Investigation into how the kangaroo rat can live without drinking water has involved various experiments with these small animals. Could kangaroo rats somehow store water in their bodies and slowly utilize these resources in the long periods when no free water is available from dew or rain? The simplest way to settle this question was to determine the total water content in the animals to see if it decreases as they are kept for long periods on a dry diet. If they slowly use up their water, the body should become increasingly dehydrated, and if they begin with a store of water, this should be evident from an initial high water content. Results of such experiments with kangaroo rats on dry diets for more than 7 weeks showed that the rats maintained their body content during the long period of water deprivation. When the kangaroo rats were given free access to water, they did not drink water. They did nibble on small pieces of watermelon, but this did not change appreciably the water intent in their bodies, which remained at 66.3% to 67.2% during this period. This is very close to the water content of dry-fed animals (66.5%), and the availability of free water, therefore, did not lead to any “storage” that could be meaningful as a water reserve. This makes it reasonable to conclude that physiological storage of water is not a factor in the kangaroo rat’s ability to live on dry food. What is the topic of this passage?

Read the following passage and mark the letter A, B, C or D on you answer sheet to indicate the correct answer to each of the questions.  REALITY TELEVISION       Reality television is genre of television programming which, it is claimed), presents unscripted dramatic or humorous situation, documents actual events, and features ordinary rather than professional actors. It could be described as a form of artificial or "heightened” documentary. Although the genre has existed in some form or another since the early years of television, the current explosion of popularity dates from around 2000.        Reality television covers a wide range of television programming formats, from game or quiz shows which resemble the frantic, often demeaning programmes produced in Japan in the 1980s and 1990s (a modern example is Gaki no Tsukai), to surveillance- or voyeurism- focused productions such as Big Brother.        Critics say that the term “reality television” is somewhat of a misnomer and that such shows frequently portray a modifies and highly influenced form of reality, with participants put in exotic location or abnormal situations, sometimes coached to act in certain ways by off-screen handlers, and with events on screen manipulated through editing and other post-production techniques.        Part of reality television's appeal is due to its ability to place ordinary people in extraordinary situations. For example, on the ABC show, The Bachelor, an eligible male dates a dozen women simultaneously, traveling on extraordinary dates to scenic locales. Reality television also has the potential to turn its participants into national celebrities, outwardly in talent and performance programs such as Pop Idol, though frequently Survivor and Big Brother participants also reach some degree of celebrity.        Some commentators have said that the name “reality television" is an inaccurate description for several styles of program included in the genre. In competition-based programs such as Big Brother and Survivor, and other special-living-environment shows like The Real World, the producers design the format of the show and control the day-to-day activities and the environment, creating a completely fabricated world in which the competition plays out. Producers specifically select the participants, and use carefully designed scenarios, challenges, events, and settings to encourage particular behaviours and conflicts. Mark Burnett, creator of Survivor and other reality shows, has agreed with this assessment, and avoids the word “reality" to describe his shows; he has said, "I tell good stories. It really is not reality TV. It really is unscripted drama."   In the first line, the writer says “it is claimed” because __________.

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.        The green building movement, started in the 1970s as a way to reduce environmental destruction, is changing the way buildings are constructed. In the early years, green builders were a small minority, and their goals of reducing the environmental impact of buildings were considered unrealistic. Now, however, the movement is growing, as builders have been able to take advantage of new technology.       Green builders try to make use of recycled materials, which means less waste in dumps. Also, they reduce environmental impact by reducing the energy requirements of a building. One way is to provide an alternative, non-polluting source of energy. First, with solar panels, it is possible to produce electricity from the rays of the sun. Once installed, they provide energy at no they cost and with no pollution.        Another solution is to reduce the amount of energy required in a building. It is possible to cut electricity use noticeably by improving natural lighting and installing low-energy light bulbs. To reduce the amount of fuel needed for heating or cooling, builders also add insulation to the walls so that the building stays warmer in winter and cooler in summer.        One example of this advanced design is the Genzyme Center of Cambridge, the most environmentally responsible office building in America. Every aspect of the design and building had to consider two things: the need for a safe and pleasant workplace for employees and the need to lessen the negative environmental impact. 75 percent of the building materials were recycled materials, and the energy use has been reduced by 43 percent and water use by 32 percent, compared with other buildings of the same size.        In other parts of the world, several large-scale projects have recently been developed according to green building principles. One of these is in Vauban, Germany, in an area that was once the site of army housing. The site has been completely rebuilt with houses requiring 30 percent less energy than conventional ones. These houses, heated by special non-polluting systems, are also equipped with solar panels.        A larger project is under way in China. The first phase of this project will include houses for 400 families built with solar power, non-polluting bricks, and recycled wall insulation. In a second phase, entire neighborhoods in six cities will be built. If all goes well, the Chinese government plans to copy these ideas in new neighborhoods across China.        Green building ideas, on a small or large scale, are spreading. Individuals, companies, and governments are beginning to see their benefits. Not only are they environmentally friendly, green buildings improve living and working conditions and also save money in the long run.  (Adapted from "Advanced Reading Power" by Beatrice S. Mikulecky and Linda Jeffries) What is one common characteristic shared by the Genzyme Center of Cambridge and the project in Vauban, Germany?
