Read the following passage and choose the best answer (A, B, C, D):
Fifty-five delegates representing all thirteen states except Rhode Island attended the Constitutional Convention in Philadelphia from May to September 1787. The delegates had been instructed by the Continental Congress to revise the old Articles of Confederation, but most believed that a stronger central government was needed. There were differences, however, about what structure the government should take and how much influence large states should have. Virginia was by far the most populous state, with twice as many as people as New York, four times as many as New Jersey, and ten times as many as Delaware. The leader of the Virginia delegation, James Madison, had already drawn up a plan for government, which became known as the Large State Plan. Its essence was that congressional representation would be based on population. It provided for two or more national executives. The smaller states feared that under this plan, a few large states would lord over the rest. New Jersey countered with the Small State Plan. It provided for equal representation for all states in a national legislature and for a single national executive. Angry debate, heightened by a stifling heat wave, led to deadlock. A cooling of tempers seemed to come with lower temperatures. The delegates hammered out an agreement known as the Great Compromise - actually a bundle of shrewd compromises. They decided that Congress would consist of two houses. The larger states were granted representation based on population in the lower house, the House of Representatives. The smaller states were given equal representation in the upper house, the Senate, in which each state would have two senators regardless of population. It was also agreed that there would be a single executive, the president. This critical compromise broke the logjam, and from then on, success seemed within reach.

At first glance, there is little in Horton to attract people. The other nearby towns have much more to offer: Bradfield has its river and historic buildings, while Newtown has shops and entertainment. The buildings of Horton look dirty and unloved. For shops, there is a small supermarket, a few bargain shops, a bakery which, strangely, does not sell bread and a florist which has one stand of sad-looking flowers. Even so, Horton has several advantages over its neighbouring towns. Firstly, it has a country park. Four thousand years ago, this was an important fort. There are no historic remains here now, but there are wonderful views over the countryside. On sunny weekends you can often see kids out with their parents, kicking balls or flying kites. There aren’t many job opportunities in Horton, and the roads to nearby cities aren’t really fast, but there are excellent rail links. You can be in London in an hour and a half, and other cities are less than an hour away. That means that parents can earn a good salary and still get home in time to spend the evenings with their families. Houses in Horton aren’t pretty, but they are functional and cheap. The streets are  quiet and safe, and there are plenty of parks and playgrounds. It has a library, three primary schools and a secondary school, St. Mark’s. It’s not as academically brilliant as other schools in the area, but it is friendly and offers a wide range of subjects and activities to children of all abilities and backgrounds. The town also has a swimming and a sports centre, and the community halls hold regular clubs and events for people of all ages.
1. What is the writer’s main purpose?

As computer use becomes more common, the need for security is more important than ever. One of the greatest security threats in the online world is computer hacking.
Computer hacking is the unauthorized access to a computer or network of computers. Hackers are people who illegally enter systems. They may alter or delete information, steal private information, or spread viruses that can damage or destroy files. But how exactly can a hacker get into a system to do these things? 
Most hackers use information called protocols that are built into computer software. These protocols allow computer to interact with one another. Protocols are sort of like computer police officers. When a computer connects to another system, the protocols check to see if the access is valid. The protocols can also determine how much information can be shared between the two systems. Hackers can manipulate the protocols to get unlimited access to a computer system. 
In fact, just the act of entering a computer network is considered hacking. This is commonly called passive hacking. Passive hackers get a rush from just being able to access a challenging system like a bank of military network. Another kind of hacker tries to do damage to a system. After hacking into systems, these hacker release viruses or alter, delete, or take information. Known as active hackers, they are, by far, the more dangerous of the two. 
The easiest way to protect a system is with a good password. Long and unusual passwords are harder for hackers to guess. For even greater security, some online services use “password-plus” systems. In this case, users first put in a password and then put in a second code that changes after the user accesses the site. Users either have special cards or devices that show them the new code to use the next time. Even if a hacker steals the password, they won’t have the code. Or if the hacker somehow gets the code, they still don’t know the password.

How can hackers get access to a computer system?

Marriage nowadays is a choice people make on their own, but this has not always been the case in society. Thousands of years ago, the average lifespan was shorter than it is today. A man usually lived until he was about 40 years old, while women died even sooner because of childbirth. There were many wars and illnesses, and people had to protect themselves by having more children while they were still young. The parents lived through their children.
Marriage was not so much a romantic love story but a business transaction, or deal. Most marriages were arranged between parents while their children were still very young. It was the custom that the fathers made the decision on whom their children were going to marry. The mothers had little say in it since they rarely made any decisions outside the household. The fathers would meet to arrange the wedding date and the money given for the bride on her wedding date. The more money and land a girl had, the more chances she had to marry well. Therefore, it was important that her father choose the bridegroom very well. Usually, it was someone who came from a good family or who was rich too. It was very unlikely that people married outside their social class. A few well-off and rich merchants got to marry poorer noblewomen and became King’s business advisors. In a way, poor peasants had an easier choice as it was less important whom they married.
The practice of arranged marriage is still common in some countries in the Middle East, such as India or Pakistan. Here, social classes are still strongly divided and very well-kept. Often, however, arranged marriages are a sign that people do not want to let go of the past, which gives them comfort and security in an ever-changing world.

In 1959, the government of Egypt was working on a plan to build a dam on the River Nile. It was called the Aswan Dam, and it was intended to generate electricity and allow the river water to be used for agriculture. There was one big problem with the plan, though. The dam would flood a nearby valley that contained ancient Egyptian treasures, including two enormous stone temples.
It can be difficult for governments to choose culture and history over economics. However, if countries always made decisions like this, the majority of the world's ancient sites would end up being destroyed. Luckily, UNESCO stepped in. They formed a committee that tried to convince Egypt to protect its ancient treasures. With support from many countries, they were finally successful. The huge temples were carefully removed from their original site and moved to a safe location so that the dam could be built.

After their success in saving the temples in Egypt, UNESCO went on to save more sites around the world. They protected lagoons in Venice, ruins in Pakistan, and temples in Indonesia. With industrialisation changing the world rapidly, there were many sites that needed to be saved. Eventually, UNESCO formed the World Heritage Organisation to protect important natural and historic sites wherever it was necessary.

By now, the World Heritage Organisation has protected hundreds of sites ranging from beautiful natural islands to buildings in large cities and ancient ruins. If you're able to visit any of the many protected sites, you'll agree it was worth it.

The word “this” in paragraph 2 refers to ____________.

Certain birds are, more often than not, considered bad luck, or even a sign of impending death. For example, all over the world, both crows and ravens have some connection to war, and death. In early times, crows and ravens were thought to accompany the gods of war, or be signs of the gods’ approaching arrival. This idea later changed. Crows in particular were thought to be harbingers of ill fortune or, in some cases, guides to the afterlife. Woe be it to the person who saw a single crow or raven flying overhead, for this was most certainly a portent of death in the near future.
 Interestingly, though potentially bad luck for people individually, the raven is considered to be good luck for the crown of England. So much so, in fact, that a “raven master” is, even today, an actual government position in London. He takes care of the ravens there and also clips their wings, ensuring that these birds can never fly far from the seat of the British government. This way, the kingdom will never fall to ill fortune.
 Another bird that is thought to play a part in forecasting the fortunes of people is the swallow. Depending on how and when it is seen, the swallow can be a harbinger of either good or ill fortune. Perhaps inspired by the swallow’s red-brown breast, Christian people initially related the swallow to the death of Jesus Christ. Thus, people who saw a swallow fly through their house considered it a portent of death. Later, however, farmers began to consider swallows signs of good fortune. Any barn that has swallows living in it is sure to be blessed in the following year. Farmers also have to beware of killing a swallow; that would be certain to end any good luck they might have had.
 Though many people think these superstitions are old wives’ tales, there is actually some evidence to support them. For example, crows and ravens, being scavengers, appear at the aftermath of battles. Thus, large numbers of crows and ravens could be good indications of war in an area. As well, swallows feed on insects that can cause infections in cattle. Thus, a farmer who has many swallows in his barn may actually have healthier animals on his farm. Therefore, the next time you feel inclined to laugh at an old wives’ tale, maybe you had better find out if there is any truth to it first!.

When jazz began to lose its reputation as "low-down" music and to gain well-deserved acclaim among intellectuals, musicians began to feature many instruments previously considered inappropriate for jazz. Whereas before the 1950s, jazz musicians played only eight basic instruments in strict tempo, in this decade they started to improvise on the flite, electric organ, piccolo, accordion, cello, and even bagpipes, with the rhythm section composed for strings or piano. Big bands no longer dominated jazz, and most changes emerged from small combos, such as the Dave Brubeck Quartet and the Gerry Mulligan Quartet. The Gerry Mulligan Quartet proved that a small, modern band could sound complete without a piano; the rhythm section consisted only of a set of drums and a string bass. Jazz continued to move in new directions during the 1960s. Saxophonist and composer Ornette Coleman led a quartet playing "free" jazz that was atonal. Pianist Cecil Taylor also conducted similar experiments with music, and John Coltrane included melodies from India in his compositions. In the 1970s musicians blended jazz and rock music into fusion jazz which combined the melodies and the improvisations of jazz with the rhythmic qualities of rock'n' roll, with three or five beats to the bar and in other meters. The form of jazz music was greatly affected by electric instruments and electronic implements to intensify, distort, or amplify their sounds. However, the younger musicians of the time felt compelled to include a steady, swinging rhythm which they saw as a permanent and essential element in great jazz.
3. According to the passage, the changes in jazz music in the 1970s came from:

Continents and ocean basins represent the largest identifiable bodies on Earth. On the solid portion of the planet, the second most prominent features are flat plains, elevated plateaus, and large mountain ranges. In geography, the term "continent" refers to the surface of continuous landmasses that together comprise about 29.2% of the planet's surface. On the other hand, another definition is prevalent in the general use of the term that deals with extensive mainlands, such as Europe or Asia,that actually represent one very large landmass. Although all continents are bounded by the water bodies or high mountain ranges, isolated mainlands, such as Greenland and India-Pakistan areas are called subcontinents. In some circles, the distinction between continents and large islands lies almost exclusively in the size of a particular landmass. The analysis of compression and tension in the earth's crust has determined that continental structures are composed of layers that underlie continental shelves. A great deal of disagreement among geologists surrounds the issue of exactly how many layers underlie each landmass because of their distincive mineral and chemical composition. It's also quite possible that the ocean floor rests on top of unknown continents that have not yet been explored. The continental crust is believed to have been forrmed by means of a chemical reaction when lighter materials separated from heavier ones,thus settling at various levels within the crust. Assisted by the measurements of the specifics within crust formations by means of monitoring earthquakes, geologists can speculate that a chemical split occured to form the atmosphere, sea water and the crust before it solidified many centuries ago. Although each continent has its special features, all consist of various combinations of components that include shields,moutain belts, intracratonic basins, margins, volcanic plateaus, and blockvaulted belts. The basic differences among continents lie in the proportion and the composition of these features relative to the continent size. Climatic zones have a crucial effect on the weathering and formation of the surface features, soil erosion, soil deposition, land formation, vegetation, and human activities. Moutian belts are elongated narrow zones that have a characteristic folded sedimentary organization of layers. They are typically produced during substabtial crustal movements, which generate faulting and moutain building. When continental margins collide, the rise of a marginal edge leads to the formation of large moutain ranges, as explained by the plate tectonic theory. This process also accounts for the occurrence of mountain belts in ocean basins and produces evidence for the ongoing continental plate evolution.

Tulips are Old World, rather than New World, plants, with the origins of the species lying in Central Asia. They became an integral part of the gardens of the Ottoman Empire from the sixteenth century onward, and, soon after, part of European life as well. Holland, in particular, became famous for its cultivation of the flowers. A tenuous line marked the advance of the tulip to the New World, where it was unknown in the wild. The first Dutch colonies in North America had been established in New Netherlands by the Dutch West India Company in 1624, and one individual who settled in New Amsterdam (today's Manhattan section of New York City) in 1642 described the flowers that bravely colonized the settlers' gardens. They were the same flowers seen in Dutch still-life paintings of the time: crown imperials, roses, carnations, and of course tulips. They flurished in Pennsylvania too, where in 1698 William Penn received a report of John Tateham's "Great and Stately Palace," its garden full of tulips. By 1760, Boston newspapers were advertising 50 different kinds of mixed tulip "roots." But the length of the journey between Europe and North America created many difficulties. Thomas Hancock, an English settler, wrote thanking his plant supplier for a gift of some tulip bulbs from England, but his letter the following year grumbled that they were all dead. Tulips arrived in Holland, Michigan, with a later wave of early nineteenth-century Dutch immigrants who quickly colonized the plains of Michigan. Together with many other Dutch settlements, such astheone at Pella, Iowa, they established a regular demand for European plants. The demand was bravely met by a new kind of tulip entrepreneur, the traveling salesperson. One Dutchman, Hendrick van de Schoot, spent six months in 1849 traveling through the United States taking orders for tulip bulbs. While tulip bulbs were traveling from Europe to the United States to satisfy the nostalgic longings of homesick English and Dutch settlers, North American plants were traveling in the opposite direction. In England, the enthusiasm for American plants was one reason why tulips dropped out of fashion in the gardens of the rich and famous

Butterflies are among the most extensively studied insects, an estimated 90 percent of the world's species have their scientific names. As a consequence, they are, perhaps, the best group of insects for examining patterns of terrestrial biotic diversity and distribution. Butterflies also have a favorable image with the general public. Hence, they are an excellent group for communicating information on science and conservation issues such as diversity. Perhaps the aspect of butterflies diversity that has received the most attention over the past century is the striking difference in species richness between tropical and temperate regions. For example, in 1875 one biologist pointed out the diversity of butterflies in the Amazon when he mentioned that about 700 species were found within an hour's walk, whereas the total number found on the British islands did not exceed 66, and the whole of Europe supported only 321. This early comparison of tropical and temperate butterflies' richness has been well confirmed. A general theory of diversity would have to predict not only this difference between temperate and tropical zones, but also patterns within each region, and how these patterns vary among different animal and plant groups. However, for butterflies, variation of species richness within temperate or tropical regions, rather than between them, is poorly understood. Indeed, comparisons of numbers of species among the Amazon basin, tropical Asia, and Africa are still mostly "personal communication" citations, even for vertebrates. In other words, unlike comparison between temperate and tropical areas, these patterns are still in the documentation phase. In documenting geographical variation in butterflies' diversity, some arbitrary, practical decisions are made. Diversity, number of species, and species richness are used synonymously; little is known about the evenness of butterfìy distribution. The New World butterflies make up the preponderance of examples because they are the most familiar species. It is hoped that by focusing on them, the errors generated by imperfect and incomplete taxonomy will be minimized

   A rather surprising geographical feature of Antarctica is that a huge freshwater, one of the world’s largest and deepest, lies hidden there under four kilometers of ice. Now known as Lake Vostok, this huge body of water is located under the ice block that comprises Antarctica. The lake is able to exist in its unfrozen state beneath this block of ice because its waters are warned by geothermal heat from the earth’s core. This thick glacier above Lake Vostok actually insulates it from frigid temperatures (the lowest ever recorded on Earth) on the surface.

   The lake was first discovered in the 1970s while a research team was conducting an aerial survey of the area. Radio waves from the survey equipment penetrated the ice and revealed a body of water of indeterminate size. It was not until much more recently that data collected by satellite made scientists aware of the tremendous size of the lake; satellite-borne radar detected an extremely flat region where the ice remains level because it is floating on the water of the lake.

   The discovery of such a huge fresh water lake trapped under Antarctica is of interest to the scientific community because of the potential that the lake contains ancient microbes that have survived for thousands upon thousands of years, unaffected by factors such as nuclear fallout and elevated ultraviolet light that have conducting research on the lake in such a harsh climate and in the problems associated with obtaining uncontaminated sampled from the lake without actually exposing the lake to contamination. Scientists are looking for possible ways to accomplish this.

Music can bring US to tears or to our feet, drive US into battle or lull US to sleep. Music is indeed remarkable in its power over all humankind, and perhaps for that every reason, no human culture on earth has ever lived without it. From discoveries made in France and Slovenia even Neanderthal man, as long as 53,000 years ago, had developed surprisingly sophisticated, sweet-sounding flutes carved from animal bones. It is perhaps then, no accident that music should strike such a chord with the limbic system - an ancient part of our brain, evolutionarily speaking, and one that we share with much of the animal kingdom. Some researchers even propose that music came into this world long before the human race ever did. For  example, the fact that whale and human music have so much in common even though our evolutionary paths have not interested for nearly 60 million years suggests that music may predate humans. They assert that rather than being the inventors of music, we are latecomers to the musical scene. Humpback whale composers employ many of the same tricks that human songwriters do. In addition to using similar rhythms, humpbacks keep musical phrases to a few seconds, creating themes out of several phrases before singing the next one. Whale songs in general are no longer than symphony movements, perhaps because they have a similar attention span. Even though they can sing over a range of seven octaves, the whales typically sing in key, spreading adjacent notes no farther apart than a scale. They mix percussive and pure tones in pretty much the same ratios as human composers - and follow their ABA form, in which a theme is presented, elaborated on and then revisited in a slightly modified form. Perhaps most amazingly, humpback whale songs include repeating refrains that rhyme. It has been suggested that whales might use rhymes for exactly the same reasons that we do: as devices to help them remember. Whale songs can also be rather catchy. When a few humpbacks from the Indian Ocean strayed into the Pacific, some of the whales they met there quickly changed their tunes - singing the new whales'songs within three short years. Some scientists are even tempted to speculate that a universal music awaits discovery.

Most forms of property are concrete and tangible, such as houses, cars, furniture or anything else that is included in one’s possessions. Other forms of property can be intangible and copyright deals with intangible forms of property. Copyright is a legal protection extended to authors of creative works, for example, books, magazine articles, maps, films, plays, television shows, software, paintings, photographs, music, choreography in dance and all other forms of intellectual or artistic property. Although the purpose of artistic property is usually public use and enjoyment, copyright establishes the ownership of the creator. When a person buys a copyrighted magazine, it belongs to this individual as a tangible object. However, the authors of the magazine articles own the research and the writing that went into creating the articles. The right to make and sell or give away copies of books or articles belongs to the authors, publishers, or other individuals or organizations that hold the copyright. To copy an entire book or a part of it, permission must be received from the copyright owner, who will most likely expect to be paid. Copyright law distinguishes between different types of intellectual property. Music may be played by anyone after it is published. However, if it is performed for profit, the performers need to pay a fee, called a royalty. A similar principle applies to performances of songs and plays. On the other hand, names, ideas, and book titles are accepted. Ideas do not become copyrighted property until they are published in a book, a painting or a musical work. Almost all artistic work created before the 20th century is not copyrighted because it was created before the copyright law was passed. The two common ways of infringing upon the copyright are plagiarism and piracy. Plagiarizing the work of another person means passing it off as one’s own. The word plagiarism is derived from the Latin plagiarus, which means “abductor”. Piracy may be an act of one person, but, in many cases, it is a joint effort of several people who reproduce copyrighted material and sell it for profit without paying royalties to the creator. Technological innovations have made piracy easy and anyone can duplicate a motion picture on videotape, a computer program, or a book. Video cassette recorders can be used by practically anyone to copy movies and television programs, and copying software has become almost as easy as copying a book. Large companies zealously monitor their copyrights for slogans, advertisements, and
brand names, protected by a trademark.

Fiberscopes are one of the most are one of the most important outcomes of he science of fiber optics. Fibers made of glass and transparent acrylic plastic are capable of conveying light energy, and when thousands of these fibers are combined in what is called a fiberscope, they can transmit images. The most common fiberscopes contain about 750,000 fibers, each 0.001 centimeter, or 10 microns, in diameter. For certain uses, the diameter of the fiber may be as small as 5 microns. Fiberscopes have a wide range of applications. In the medical field, physicians use fiberscopes to examine internal organs and as an aid in delicate surgeries. Miniature probes have also been developed to view muscle fiber, skin tissue, and blood cells. Fiberscopes have also found varied uses in industry, particularly to inspect or control operations in inaccessible areas. Bundles of fiberscopes fused together in a solid plate, called a faceplate, are being used in the manufacture of television tubes and other cathode- ray tube devices. The most far reaching applications of fiber-optic technology are in communication. Optical fibers carry voice messages for telephone service. The sound of the voice is electronically broken down into thousands of pulses per second, which causes a transmitting laser to send coordinated pulses of light through the optical fibers. At the receiving end, the light pulses are converted to electrical signals and the voice message is reconstructed. Light-wave communication systems can handle an immensely greater number of telephone calls and television programs than the current system, and they will form the basis of the “electronic superhighway” expected to crisscross the nation in the near future of the information age.

To understand other people's emotions, you should be sympathetic to other people's misfortunes and congratulate them on their achievements. To do this, you need to be aware of what is going on in other people's lives. It's crucial to maintain eye contact and do not be afraid to ask others for their opinions as this will help to make them feel valued.
