Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions from 43 to 50. The need for a surgical operation, especially an emergency operation, almost always comes as a severe shock to the patient and his family. Despite modern advances, most people still have an irrational fear of hospitals, and anaesthetics. Patients do not often believe they really need surgery - cutting into a part of the body as opposed to treatment with drugs. In the early years of the 20th century there was little specialization in surgery. A good surgeon was capable of performing almost every operation that had been advised up to that time. Today the situation is different. Operations are now being carried out that were not even dreamed of fifty years ago. The heart can be safely opened and its valves repaired. Clogged blood vessels can be cleaned out, and broken ones mended or replaced. A lung, the whole stomach, or even part of the brain can be removed and still permit the patient to live comfortable and satisfactory life. However, not every surgeon wants to, or is qualified to carry out every type of modern operation. The scope of surgery has increased remarkably in the past decades. Its safety has increased too. Deaths from most operations are about 20% of what they were in 1910 and surgery has been extended in many directions, for example to certain types of birth defects in new born babies, and, at the other end of the scale, to life saving operations for the octogenarian. The hospital stay after surgery has been shortened to as little as a week for most major operations. Most patients are out of bed on the day after an operation and may be back at work in two or three weeks. Many developments in modern surgery are almost incredible. They include replacement of damaged blood vessels with simulated ones made of plastic: the replacement of heart valves with plastic substitutes; the transplanting of tissues such as lens of the eye; the invention of the artificial kidney to clean the blood of poisons at regular intervals and the development of heart and lung machines to keep patients alive during very long operations. All these things open a hopeful vista for the future of surgery. One of the most revolutionary areas of modem surgery is that of organ transplants. Until a few decades ago, no person, except an identical twin, was able to accept into his body the tissues of another person without reacting against them and eventually killing them. Recently, however, it has been discovered that with the use of X-rays and special drugs, it is possible to graft tissues from one person to another which will survive for periods of a year or more. Kidneys have been successfully transplanted between non-identical twins. Heart and lung transplants have also been reasonably successful. "Spare parts" surgery, the simple routine replacement of all worn-out organs by new ones, is still a dream of the future but surgery is ready for such miracles. In the meantime, you can be happy if your doctors say to you, "Yes, I think it is possible to operate on you for this condition." Question 44: Surgeons in the early 20th century, compared with modem ones _______.

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 35 to 42.   The concept of being environmentally conscious, or “green,” has become more prevalent in twenty first-century U.S. culture. It has begun to affect the manufacturing of everything from non-toxic household cleaning products to motor vehicles powered by alternative sources of energy. However, one way of being “green” that is perhaps not as apparent to the viewer but of equal importance in being environmentally conscious, is the construction of buildings that are considered “sustainable.” Sustainable buildings are those that do not impose on the environment or rely on the over-utilization of energy or natural resources. There are four main principles of sustainability, which include consideration of the health and stability of all living things and their environmental diversity, as well as the economic opportunities of humanity.   Sustainable architecture consists of environmentally conscious design techniques. In the past, the demolition of an old building meant that all or most of the debris of the building would end up in a landfill or a waste disposal site. Today, architects can plan and design a building that uses recycled materials, such as wood, concrete, stone, or metal. These materials are salvaged from the demolition of an older building and can be appropriately incorporated into a new construction. Architects and construction supervisors may also choose to recycle more organic parts of demolished buildings, such as wooden doors, windows and other glass, ceramics, paper, and textiles.   A problem that has often arisen has been with how a site crew-whether it is demolition or construction crew determines and sorts what is “waste” and what is recyclable. Architects and environmental scientists have to decide whether or not a material is appropriate for use in new construction and how it will impact the environment. They must evaluate the materials from the demolition and determine what those materials contain, and if they meet the standards set by the U.S. government’s Environmental Protection Agency (the EPA). If the debris from the demolition contains hazardous materials that are harmful to the environment or to the consumer, such as asbestos, then the material is not salvageable. Use of asbestos for insulation and as a form of fire retardation in buildings and fabrics was common in the nineteenth century. Asbestos was once used in shingles on the sides of old buildings, as well as in the insulation in the interior walls of homes or other construction. In new “green” construction, insulation that was once asbestos-based can be replaced with recycled denim or constructed with cellulose-a fibrous material found in paper products. The same assessment applies to wood or wallboard painted with toxic lead-based paints. In addition, gas-flow regulators and meters on both water and gas heating systems constructed prior to 1961 must be carefully evaluated to determine that they do not contain dangerous substances such as mercury. Mercury can be harmful to humans and the environment if it is spilled during the removal of these devices. In paragraph 3, the author mentions all of the following hazardous materials found in debris from a demolition site EXCEPT _____________ .

Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions from 36 to 42. Life originated in the early seas less than a billion years after the Earth was formed. Yet another three billions years were to pass before the first plants and animals appeared on the continents. Life's transition from the sea to the land was perhaps as much of an evolutionary challenge as was the genesis of life. What forms of life were able to make such a drastic change in lifestyle? The traditional view of the first terrestrial organisms is based on megafossils - relatively large specimens of essential whole plants and animals. Vascular plants, related to modern seed plants and ferns, left the first comprehensive megafossil record. Because of this, it has been commonly assumed that the sequence of terrestrialization reflected the evolution of 10 modern terrestrial ecosystems. In this view, primitive vascular plants first colonized the margins of continental waters, followed by animals that fed on the plants, and lastly by the animals that preyed on the plant-eaters. Moreover, the megafossils suggest that terrestrial life appeared and diversified explosively near the boundary between the Silurian and the Devonian periods, a little more than 400 million years ago. Recently, however, paleontologists have been taking a closer look at sediments below this Silurian- Devonian geological boundary. It turns out that some fossils can be extracted from these sediments by putting the rock in an acid bath. The technique has uncovered new evidence from sediments that were deposited near the shores of the ancient oceans - plant microfossils and microscopic pieces of small animals. In many instances, the specimens are less than one-tenth of a millimeter in diameter. Although they were entombed in the rocks for hundreds of millions of years, many of the fossils consist of the organic remains of the organism. These discovered fossils have not only revealed the existence ofpreviously unknown organisms, but have also pushed back these dates for the invasion of land by multicellular organisms. Our view about the nature of the early plants and animal communities are now being revised. And with those revisions come new speculations about the first terrestrial life-forms. Question 42: With which of the following conclusions would the author probably agree?

In many instances, the specimens are less than one-tenth of a millimeter in diameter. Although they were entombed in the rocks for hundreds of millions of years, many of the fossils consist of the organic remains of the organism.

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 28 to 34.   Although speech is the most advanced form of communication, there are many ways of communicating without using speech. Signals, signs, symbols, and gestures may be found in every known culture. The basic function of signal is to impinge upon the environment in such a way that it attracts attention, for example, the dots and dashes of a telegraph circuit. Coded to refer to speech, the potential for communication is really great. Less adaptable to the codification of words, signs also contain meaning in and of themselves. A stop sign or barber pole conveys meaning quickly and conveniently. Symbols are more difficult to describe than either signals or signs because of their intricate relationship with the receiver’s cultural perceptions. In some culture, applauding in a theater provides performers with an auditory’ symbol of approval. Gestures such as waving and handshaking also convey certain cultural messages.   Although signals, signs, symbols, and gestures are very useful, they do have a major disadvantage. They usually do not allow ideas to be shared without the sender being directly adjacent to the receiver. As a result, means of communication intended to be used for long distances and extended periods are based upon speech. Radio, television, and the telephone are only a few. Why were the telephone, radio, and the television invented?

Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions from 36 to 42. Life originated in the early seas less than a billion years after the Earth was formed. Yet another three billions years were to pass before the first plants and animals appeared on the continents. Life's transition from the sea to the land was perhaps as much of an evolutionary challenge as was the genesis of life. What forms of life were able to make such a drastic change in lifestyle? The traditional view of the first terrestrial organisms is based on megafossils - relatively large specimens of essential whole plants and animals. Vascular plants, related to modern seed plants and ferns, left the first comprehensive megafossil record. Because of this, it has been commonly assumed that the sequence of terrestrialization reflected the evolution of 10 modern terrestrial ecosystems. In this view, primitive vascular plants first colonized the margins of continental waters, followed by animals that fed on the plants, and lastly by the animals that preyed on the plant-eaters. Moreover, the megafossils suggest that terrestrial life appeared and diversified explosively near the boundary between the Silurian and the Devonian periods, a little more than 400 million years ago. Recently, however, paleontologists have been taking a closer look at sediments below this Silurian- Devonian geological boundary. It turns out that some fossils can be extracted from these sediments by putting the rock in an acid bath.

* 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 24 to 30. MEGACITY: A NEW KIND OF CITY   A term 'megalopolis' (or megacity) was first used by French geographer Jean Gottman to describe the north-eastern United States in 1961. The term is used more widely now and is defined as an urban area of more than 10 million inhabitants dominated by a low-density housing. In 1995 there were 14 megacities. By 2020 there could be 30.   Megacities are the result of the process of urbanization. After cities grew into crowded urban centres, people who could afford to move into suburbs at the edge of the city. When the suburbs in turn became crowded, people moved into villages and dormitory towns outside the city, but within commuting distance. In this way, for the first time since industrialisation, the countryside began to gain population, whereas cities lost their inhabitants. In the 1980s St Louis and Detroit in the America lost between 35 and 47 per cent of their populations and London lost 15 per cent in the 20 years to 1971.   However, this movement away from cities does not mean that the city is dying. In fact it is spreading. From the old city develops a metropolitan area with many low-level urban developments. When these metropolitan areas merge together, they form megacities which contain over 10 million people. The largest of these is in America, called Boswash - a region over 300 miles long from Boston in the north to Washington, DC in the south with more than 44 million people. There are emerging megalopolises in Britain centred around London and the south-east, in Germany in the industrial region of the Ruhr and Japan in the Tokyo-Osaka-Kyoto region. (adaptedfrom Archive IELTS (2013), Louis Harrison et al., Cengage Learning) The highlighted word "these" in the passage refers to_________.
