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:
Around 365 B.C. in ancient Greece, the great teacher Plato told a story about a place called Atlantis. Plato described Atlantis as a continent in the Atlantic Ocean. He said it had been the home of a powerful people who were destroyed when the continent was swallowed by the sea.
Ever since Plato’s time, people have wondered if the story about Atlantis was really true. Was there ever such a place as Atlantis? During the Middle Ages, many people believed in the legend of Atlantis. Some men even made voyages to find the “lost continent”. Later, most people believed Atlantis to be just a myth. Scientists could find no evidence to show that such a place had ever existed.
Ideas change in time, however, for now some scientists think that Atlantis might have been a real place. A Greek professor has offered a new theory. He says that Atlantis was not a continent in the Atlantic Ocean but an island called Thera in the Aegean Sea. The professor says that 3,500 years ago much of Thera collapsed into the sea when a volcano erupted. He thinks that before the explosion Thera had been the home of a people called Minoans. The Minoans were sea traders who ruled the Aegean Sea from 2,000
B.C. to 1,250 B.C.
Scientist who have come to investigate Thera have found an ancient city buried beneath volcanic ash and stone. It appears that the people who lived in the city had an advanced civilization. They were probably Minoans.
Is Thera the “lost continent” of Atlantis? No one may ever know for certain. Atlantis may remain a riddle without an answer.

Who were the ancient Minoans?

For hundreds of years, giving flowers have been a social means of communication. In the United States, flowers are often given during rites of passage, for commemorating special occasions or as a heartfelt gift between loved ones and friends. Flower gifting also occurs in most countries around the world. However, the meanings and traditions often vary.
While students traditionally gave their favorite teacher an apple in past years, in China, teachers are given flowers. Peonies are by far the  flower most often  given  in  China. They are also quite popularly used for weddings. Strangely, potted plants are not considered a pleasant gift among Asian cultures. The people believe that like a plant confined by a pot, the gift  symbolizes a binding or restriction.
In Russia, in lieu of giving birthday presents, the guest of honor receives a single flower or an unwrapped bouquet. Floral arrangements or baskets are not given. Russians celebrate a holiday known as Woman's Day. Traditional gifts include red roses, hyacinths or tulips. When   there is a funeral or other occasion where someone wishes to express sympathy, carnations, lilies or roses are given in circular configurations, which signify the transition of birth, life and death to   rebirth. In this instance, the color of choice is commonly yellow. For joyous occasions, arrangements and bouquets generally contain an odd number of flowers.
In the times of ancient Rome, brides carried flowers to scare away evil spirits and encourage fertility. The Dutch believed that flowers were food for the soul. When invited to someone's home in Great Britain, it is tradition to bring a gift of flowers. All types are acceptable except white lilies, which are usually seen at funerals. Unlike the United States, red roses are a symbol of love.
Flowers are generally gifted in odd numbered increments regardless of the occasion. However, the Brits also have superstitions regarding the number 13, so the number is avoided.
In the southern region of the continent, flowers are traditionally given during Christmas. Egyptians are much more conservative and restrict flower gifting to funerals and weddings. While certain flowers may have significant meanings for some, flowers in Las Vegas and across the United States flowers are an accepted gift for any reason desired.

There is a common expression in the English language referring to a blue moon. When people say that something happens “only once in a blue moon,” they mean that it happens only very rarely, once in a great while. This expression has been around for at least a century and a half; there are references to this expression that date from the second half of the nineteenth century. (5) The expression “a blue moon” has come to refer to the second full moon occurring in any given calendar month. A second full moon is not called a blue moon because it is particularly blue or is any different in hue from the first full moon of the month. Instead, it is called a blue moon because it is so rare. The moon needs a little more than 29 days to complete the cycle from full moon to full moon. Because every month except February has more than 29 days, every month will have at least one full moon (except February, which will have a full moon unless there is a full moon at the very end of January and another full moon at the very beginning of March). It is on the occasion when a given calendar month has a second full moon that a blue moon occurs. This does not happen very often, only three or four times in a decade. The blue moons of today are called blue moons because of their rarity and not because of their color; however, the expression “blue moon” may have come into existence in reference to unusual circumstances in which the moon actually appeared blue. Certain natural phenomena of gigantic proportions can actually change the appearance of the moon from Earth. The eruption of the Krakatao volcano in 1883 left dust particles in the atmosphere, which clouded the sun and gave the moon a bluish tint. This particular occurrence of the blue moon may have given rise to the expression that we use today. Another example occurred more than a century later. When Mount Pinatubo erupted in the Philippines in 1991, the moon again took on a blue tint.

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:
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.

According to the passage, what happened about 400 million years ago?

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:
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 weight. There was no trend toward a decrease in water 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 itent 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.

According to the passage, the results of the experiments with kangaroo rats showed that

In 1900 the United States had only three cities with more than a million residents-New York, Chicago, and Philadelphia. By 1930, it had ten giant metropolises. The newer ones experienced remarkable growth, which reflected basic changes in the economy. The population of Los Angeles (114,000 in 1900) rose spectacularly in the early decades of the twentieth century, increasing a dramatic 1,400 percent from 1900 to 1930.
A number of circumstances contributed to the meteoric rise of Los Angeles. The agricultural potential of the area was enormous if water for irrigation could be found, and the city founders had the vision and dating to obtain it by constructing a 225-mile aqueduct, completed in 1913, to tap the water of the Owens River. The city had a superb natural harbor, as well as excellent rail connections. The climate made it possible to shoot motion pictures year-round; hence Hollywood not only supplied jobs but also disseminated an image of the good life in Southern California on screens all across the nation. The most important single industry powering the growth of Los Angeles, however, was directly linked to the automobile. The demand for petroleum to fuel gasoline engines led to the opening of the Southern California oil fields, and made Los Angeles North America’s greatest refining center.
Los Angeles was a product of the auto age in another sense as well: its distinctive spatial organization depended on widespread private ownership of automobiles. Los Angeles was a decentralized metropolis, sprawling across the desert landscape over an area of400 square miles.
It was a city without a real center. The downtown business district did not grow apace with the city as a whole, and the rapid transit system designed to link the center with outlying areas withered away from disuse. Approximately 800,000 cars were registered in Los Angeles County in 1930, one per 2.7 residents. Some visitors from the east coast were dismayed at the endless urban sprawl and dismissed Los Angeles as a mere collection of suburbs in search of a city. But the freedom and mobility of a city built on wheels attracted floods of migrants to the city.

The author characterizes the growth of new large cities in the United States after 1900 as resulting primarily from     .

The elements other than hydrogen and helium exist in such small quantities that it is accurate to say that the universe is somewhat more than 25 percent helium by weight and somewhat less than 75 percent hydrogen.
Astronomers have measured the abundance of helium throughout our galaxy and in other galaxies as well. Helium has been found in old stars, in relatively young ones, in interstellar gas, and in the distant objects known as quasars. Helium nuclei have also been found to be constituents of cosmic rays that fall on the earth (cosmic rays are not really a form of radiation; they consist of rapidly moving particles of numerous different kinds). It doesn’t seem to make very much difference where the helium is found. Its relative abundance never seems to vary much. In some places, there may be slightly more of it; in others, slightly less, but the ratio of helium to hydrogen nuclei always remains about the same.
Helium is created in stars. In fact, nuclear reactions that convert hydrogen to helium are responsible for most of the energy that stars produce. However, the amount of helium that could have been produced in this manner can be calculated, and it turns out to be no more than a few percent. The universe has not existed long enough for this figure to be significant greater. Consequently, if the universe is somewhat more than 25 percent helium now, then it must have been about 25 percent helium at a time near the beginning.
However, when the universe was less than one minute old, no helium could have existed. Calculations indicate that before this time temperature were too high and particles of matter were moving around much too rapidly. It was only after the one-minute point that helium could exist. By this time, the universe had cooled so sufficiently that neutrons and protons could stick together. But the nuclear reactions that led to the formations of helium went on for only relatively short time. By the time the universe was a few minutes old, helium production had effectively ceased.

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.

The purpose of copyright law is most comparable with the purpose of which of the following?

The concept of obtaining fresh water from iceberg that is towed to populated areas and arid regions of the world was once treated as a joke more appropriate to cartoons than real life. But now it is being considered quite seriously by many nations, especially since scientists have warned that the human race will outgrow its fresh water supply faster than it runs out of food. Glaciers are a possible source of fresh water that has been overlooked until recently. (A)
Three-quarters of the Earth's fresh water supply is still tied up in glacial ice, a reservoir of untapped fresh water so immense that it could sustain all the rivers of the world for 1,000 years. Floating on the oceans every year are 7,659 trillion metric tons of ice encased in 10,000 icebergs that break away from the polar ice caps, more than ninety percent of them from Antarctica. (B)
Huge glaciers that stretch over the shallow continental shelf give birth to icebergs throughout the year. Icebergs are not like sea ice, which is formed when the sea itself freezes; rather, they are formed entirely on land, breaking off when glaciers spread over the sea. As they drift away from the polar region, icebergs sometimes move mysteriously in a direction opposite to the wind, pulled by subsurface  currents. Because they melt more slowly than smaller pieces of ice, icebergs have been known to drift as far north as 35 degrees south of the equator in the Atlantic Ocean. (C)
The difficulty arises in other technical matters, such as the prevention of rapid melting in warmer climates and the funneling of fresh water to shore in great volume. But even if the icebergs lost half of their volume in towing, the water they could provide would be far cheaper than that produced by desalination, or removing salt from water. (D)

If the salinity of ocean waters is analyzed, it is found to vary only slightly from place to place. Nevertheless, some of these small changes are important. There are three basic processes that cause a change in oceanic salinity. One of these is the subtraction of water from the ocean by means of evaporation-conversion of liquid water to water vapor. In this manner, the salinity is increased, since the salt behind. If this is carried to the extreme, of course, white crystals of salt would be left behind.
The opposite of evaporation is precipitation, such as rain, by which water is added to the ocean. Here the ocean is being diluted so that the salinity is decreased. This may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. Thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation or runoff.
Normally, in tropical regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. Similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas.
A third process by which salinity may be altered is associated with the formation and melting of sea ice. When seawater is frozen, the dissolved materials are left behind. In this manner, seawater directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. Of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.
In the Weddell Sea, off Antarctica, the densest water in the ocean is formed as a result of this freezing process, which increases the salinity of cold water. This heavy water sinks and is found in the deeper portions of the oceans of the world.

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:
Because the low latitudes of the Earth, the areas near the equator, receive more heat than the latitudes near the poles, and because the nature of heat is to expand and move, heat is transported from the tropics to the middle and high latitudes. Some of this heat is moved by winds and some by ocean currents, and some gets stored in the atmosphere in the form of latent heat. The term “latent heat” refers to the energy that has to be used to convert liquid water to water vapor. We know that if we warm a pan of water on a stove, it will evaporate, or turn into vapor, faster than if it is allowed to sit at room temperature. We also know that if we hang wet clothes outside in the summertime, they will dry faster than in winter, when the temperature is lower. The energy used in both cases to change liquid water to water vapor is supplied by heat - supplied by the stove in the first case and by the Sun in the latter case. This energy is not lost. It is stored as vapor in the atmosphere as latent heat. Eventually, the water stored as vapor in the atmosphere will condense to liquid again, and the energy will be released to the atmosphere.
In the atmosphere, a large portion of the Sun’s incoming energy is used to evaporate water, primarily in the tropical oceans. Scientists have tried to quantify this proportion of the Sun’s energy. By analyzing temperature, water vapor, and wind data around the globe, they have estimated the quantity to be about 90 watts per square meter, or nearly 30 percent of the Sun’s energy. Once this latent heat is stored within the atmosphere, it can be transported, primarily to higher latitudes, by prevailing, large - scale winds. Or it can be transported vertically to higher levels in the atmosphere, where it forms clouds and subsequent storms, which then release the energy back to the atmosphere.

The passage mainly discusses how heat
