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:
One of the most interesting parts of the earth for many people was and continues to be the beautiful world of the sea. People were always attracted to the mysteries of the deep waters when they saw a little part of the under water world on television or in photographs. Due to this intense attraction caused by the mystery of the waters, more and more people choose to practice scuba diving, which became in time one of the most popular sports around the world. Scuba diving is a complex sport that requires some research before being understood at its real value. In order for someone to practice it, it is required for them to take some courses so accidents can be avoided.
Scuba diving is not only about diving and observing the amazing environment that exists under the waters. This sport can be transformed into a successful career by those who are truly passionate about it. At the moment, scuba diving has four main areas of interest: recreation purposes, commercial purposes, scientific research and military activity as well. The most frequent reason why people go for scuba diving is because they want to relax in a special way, by having contact with a less known world.
A great thing about this sport is that it can be practiced anytime around the year; however, you should choose the summer if you have problems with low temperatures. Once you take the lessons, you get the basic knowledge before diving, you should talk to a specialist and obtain quality equipment for this activity. For the beginning, you can  only rent scuba diving equipment,  but if you get attached to this sport, then you will have to purchase one of your own at some moment. Some of the most important parts of the scuba gear are the mask, the snorkel, the diving suit, the gloves, the boots and the diving regulator.
If you finally decided to try scuba diving and you already took some scuba courses then you must be thinking about what location to choose. This is one of  the most difficult decisions to  make  as our world is filled with numerous destinations, equally beautiful and interesting. If this passion catches you then you will surely get to visit more and more amazing locations each year. There is    no such thing as the most beautiful waters to scuba diving in as each part has something to offer    and shelters special creatures that should be observed.

Social parasitism involves one species relying on another to raise its young. Among vertebrates, the best known social parasites are such birds as cuckoos and cowbirds; the female lays egg in a nest belonging to another species and leaves it for the host to rear
The dulotic species of ants, however, are the supreme social parasites. Consider, for example, the unusual behavior of ants belonging to the genus Polyergus. All species of this ant have lost the ability to care for themselves. The workers do not forage for food, feed their brood or queen, or even clean their own nest. To compensate for these deficits, Polyergus has become specialized at obtaining workers from the related genus Formica to do these chores
In a raid, several thousand Polyergus workers will travel up to 500 feet in search of a Formica nest, penetrate it, drive off the queen and her workers, capture the pupal brood, and transport it back to their nest. The captured brood is then reared by the resident Formica workers until the developing pupae emerge to add to the Formica population, which maintains the mixed- species nest. The Formica workers forage for food and give it to colony members of both species. They also remove wastes and excavate new chambers as the population increases
The true extent of the Polyergus and dependence on the Formica becomes apparent when the worker population grows too large for existing nest. Formica scouts locate a new nesting site, return to the mixed-species colony, and recruit additional Formica nest mates. During a period that may last seven days, the Formica workers carry to the new nest all the Polyergus eggs, larvae, and pupae, every Polyergus adult, and even the Polyergus queen
Of the approximately 8000 species of ants in the world, all 5 species of Polyergus and some 200 species in other genera have evolved some degree of parasitic relationship with other ants

The modem comic strip started out as ammunition in a newspaper was between giants of the American press in the late nineteenth century. The first full-color comic strip appeared in January 1894 in the New York World, owned by Joseph Pulitzer. The first regular weekly full- color comic supplement, similar to today's Sunday funnies, appeared two years later, in William Randolph Hearst's rival New York paper, the Morning Journal.
Both were immensely popular, and publishers realized that supplementing the news with comic relief boosted the sale of papers. The Morning Journal started another feature in 1896, the "Yellow Kid," the first continuous comic character in the United States, whose creator, Richard Outcault, had been lured away from the World by the ambitious Hearst. The "Yellow Kid" was in many ways a pioneer. Its comic dialogue was the strictly urban farce that came to characterize later strips, and it introduced the speech balloon inside the strip, usually placed above the characters' heads.
The first strip to incorporate all the elements of later comics was Rudolph Dirks's "Katzenjammer Kids", based on Wilhelm Busch's Max and Moritz, a European satire of the nineteenth century. The "Kids" strip, first published in 1897, served as the prototype for future American strips. It contained not only speech balloons, but a continuous cast of characters, and was divided into small regular panels that did away with the larger panoramic scenes of the earliest comics.
Newspaper syndication played a major role in spreading the popularity of comic strips throughout the country. Though weekly colored comics came first, daily black-and-white strips were not far behind. They first appeared in the Chicago American in 1904. It was followed by many imitators, and by 1915 black-and-white comic strips had become a staple of daily newspaper; around the country.

The passage suggests that comic strips were popular for which of the following reasons?

   They call Jamaica the "Island in the sun" and that is my memory of it. Of sunshine, warmth and abundant fruit that was growing everywhere, and of love. There were two sisters ahead of me in the family, and though of course I didn't know it, there was an exciting talk of emigration, possibly to Canada but more usually to England, the land of opportunity. I guess that plans were already being made when I was born, for a year or so later my Dad left for London. Two years after that my mum went as well and my sisters and I were left in the care of my grandmother.

   Emigrating to better yourself was a dream for most Jamaicans, a dream many were determined to fulfill. Families were close and grandmothers were an important part of the family. So, when the mass emigrations began, it seemed perfectly right and natural for them to take over the running of families left behind.

   Grandmothers are often strict, but usually also spoil you. She ran the family like a military operation: each of us, no matter how young, had our tasks. Every morning, before we went to school, we all had to take a bucket appropriate to our size and run a relay from the communal tap to the barrels until they are full. My sisters had to sweep the yard before they went to school. My grandmother would give orders to the eldest and these were passed down- as I got older I found this particularly annoying! But I can tell you, no one avoided their duties.

   My Dad came over from England to see how we were getting on . He talked to us about the new country, about snow, about the huge city, and we all wanted to know more, to see what it was like. I didn't know it at that time., but he had come to prepare us for the move to England. Six months later my grandmother told me that I was going to join my parents and that she, too, was emigrating.

   London was strange and disappointing. There was no gold on the pavements, as the stories in Jaimaica had indicated. The roads were busy, the buildings were grey and dull, with many tall, high-rise blocks. It was totally unlike Jamaica, the houses all small and packed close together. In my grandmother's house I had a big bedroom, here I had to share.

   Then came the biggest shock: snow. While flakes came out of the sky and Dad smiled, pointed and said: "That's snow!" I rushed outside, looked up and opened my mouth to let the flakes drop in. The snow settled on my tongue and it was so cold that I cried. My toes lost all feeling. As my shoes and socks got wet and frozen, there came an excruciating pain and I cried with the intensity of it. I didn't know what was happening to me.

When the writer first went to London, he was disappointed because ________.

If you could travel back in time five centuries, you'd encounter a thriving Aztec empire in Central Mexico, a freshly painted "Mona Lisa" in Renaissance Europe and cooler temperatures across the Northern Hemisphere. This was a world in the midst of the Little Ice Age (A.D. 1300 to   1850) and a period of vast European exploration now known as  the Age of  Discovery. But what if  we could look 500 years into the future and glimpse the Earth of the 26th century? Would the  world seem as different to us as the 21st century would have seemed to residents of the 16th century? For starters, what will the weather be like?
Depending on whom you ask, the 26th century will either be a little chilly or infernally hot.
Some solar output models suggest that by the 2500s, Earth's climate will have cooled back down to near Little Ice Age  conditions. Other studies predict that ongoing climate change and fossil fuel use will render much of the planet too hot for human life by 2300.
Some experts date the beginning of human climate change back to the Industrial Revolution  in the 1800s, others to slash-and-burn agricultural practices in prehistoric times. Either way, tool- wielding humans alter their environment -- and our 26th century tools might be quite impressive indeed.
Theoretical physicist and futurist Michio Kaku predicts that in a mere 100 years, humanity will make the leap from a type zero civilization to a type I civilization on the Kardashev Scale. In  other words, we'll become a species that can harness the entire sum of a planet's energy. Wielding such power, 26th-century humans will be masters of clean energy technologies such as fusion and solar power. Furthermore, they'll be able to manipulate planetary energy in order to control global climate. Physicist Freeman Dyson, on the other hand, estimates the leap to a type I civilization would occur within roughly 200 years.
Technology has improved exponentially since the 1500s, and this pace will likely continue in   the centuries to come. Physicist Stephen Hawking proposes that by the  year 2600, this growth  would see 10 new theoretical physics papers published every 10  seconds. If  Moore's Law holds  true and both computer speed and complexity double every 18 months, then some of  these  studies may be the work of highly intelligent machines.
What other technologies will shape the world of the 26th century? Futurist and author Adrian Berry believes the average human life span will reach 140 years and that the digital  storage of human personalities will enable a kind of computerized immortality. Humans will farm the oceans, travel in starships and reside in both lunar and Martian colonies while robots explore the outer cosmos.

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 ability of falling cats to right themselves in midair and land on their feet has been a source of wonder for ages. Biologists long regarded it as an example of adaptation by natural selection, but for physicists it bordered on the miraculous.
Newton's laws of motion assume that the total amount of spin of a body cannot change unless an external torque speeds it up or slows it down. If a cat has no spin when it isreleased and experiences no external torque, it ought not to be able to twist around as it falls.
In the speed of its execution, the righting of a tumbling cat resembles a magician's trick. The gyrations of the cat in midair are too fast for the human eye to follow, so the process is obscured. Either the eye must be speeded up, or the cat's fall slowed down for the phenomenon to be observed. A century ago the former was accomplished by means of high-speed photography using equipment now available in any pharmacy. But in the nineteenth century the capture on film of a falling cat constituted a scientific experiment.
The experiment was described in a paper presented to the Paris Academy in 1894. Two sequences of twenty photographs each, one from the side and one from behind, show a white cat in the act of righting itself. Grainy and quaint though they are, the photos show that the cat was dropped upside down, with no initial spin, and still landed on its feet. Careful analysis of the photos reveals the secret; as the cat rotates the front of its body clockwise, the rear and tail twist counterclockwise, so that the total spin remains zero, in perfect accord with Newton's laws. Halfway down, the cat pulls in its legs before reversing its twist and then extends them again, with the desired end result. The explanation was that while nobody can acquire spin without torque, a flexible one can readily change its orientation, or phase. Cats know this instinctively, but scientists could not be sure how it happened until they increased the speed of their perceptions a thousandfold.

Covering more than 70 percent of our planet, oceans are among the earth’s most valuable natural resources. They govern the weather, clean the air, help feed the world, and provide a living for millions. They also are home to most of the life on earth, from microscopic algae to the blue whale, the largest animal on the planet. Yet we’re bombarding them with pollution. By their very nature—with all streams flowing to rivers, all rivers leading to the sea—the oceans are the end point for so much of the pollution we produce on land, however far from the coasts we may be. And from dangerous carbon emissions to choking plastic to leaking oil to constant noise, the types of ocean pollution humans generate are vast. As a result, collectively, our impact on the seas is degrading their health at an alarming rate. Here are some ocean pollution facts that everyone on our blue planet ought to know.
When we burn fossil fuels, we don’t pollute just the air but the oceans, too. Indeed, today’s seas absorb as much as a quarter of all man-made carbon emissions, which changes the pH of surface waters and leads to acidification. This problem is rapidly worsening—oceans are now acidifying faster than they have in some 300 million years. It’s estimated that by the end of this century, if we keep pace with our current emissions practices, the surface waters of the ocean could be nearly 150 percent more acidic than they are now.
The majority of the garbage that enters the ocean each year is plastic—and here to stay. That’s because unlike other trash, the single-use grocery bags, water bottles, drinking straws, and yogurt containers, among eight million metric tons of the plastic items we toss (instead of recycle), won’t biodegrade. Instead, they can persist in the environment for a millennium, polluting our beaches, entangling marine life, and getting ingested by fish and seabirds.
Where does all this debris originate? While some is dumped directly into the seas, an estimated 80 percent of marine litter makes its way there gradually from land-based sources―including those far inland―via storm drains, sewers, and other routes. Oil from boats, airplanes, cars, trucks, and even lawn mowers is also swimming in ocean waters. Chemical discharges from factories, raw sewage overflow from water treatment systems, and storm water and agricultural runoff add other forms of marine-poisoning pollutants to the toxic brew.
The ocean is far from a “silent world.” Sound waves travel farther and faster in the sea’s dark depths than they do in the air, and many marine mammals like whales and dolphins, in addition to fish and other sea creatures, rely on communication by sound to find food, mate, and navigate. But an increasing barrage of human-generated ocean noise pollution is altering the underwater acoustic landscape, harming—and even killing—marine species worldwide.

As mentioned in paragraph 2, acidification ______________.

The blue whale is the largest animal ever known to  have existed. During the 20th century,  the species was almost exterminated due to commercial whaling. The species has slowly recovered following the global whaling ban but it remains endangered and faces a  number of  serious threats including ship strikes and the impact of climate change.
Blue whales are simply enormous with most ranging in length from 24-30 m. The largest  ever recorded was a gargantuan 33.5 m long. Females are up to 10 m longer than males. And they can weigh up to 200 tonnes. Just to put that in perspective: an adult male African elephant weighs 6 tonnes. The blue whale's heart is the size of a small car and its beat can be detected two miles away. But that's nothing compared to their calls. Blue whales are the loudest animals on earth and their calls are louder than a jet engine: reaching 188 decibels, while a jet's engine hit 'just' 140 decibels. Apart from their gigantic size, blue whales can be identified by their relatively small dorsal fin, a fairly rounded rostrum (anterior part of the skull), and approximately 90 ventral  grooves, which reach the navel. They also have row of 300-400 baleen plates on each side of the mouth, which are black in color and range in length from 50 cm in front to 100 cm in back.
Blue whales mostly travel alone or in groups of 2-3. Larger groups of up to 60 whales have been reported and are probably associated with feeding grounds. However, the blue whale has the most powerful voice in the animal kingdom and its low-frequency sounds can travel in deep water over hundreds, or even thousands, of miles. Under these circumstances, animals which may appear to us to be traveling alone may actually be in constant contact with one another.
At birth, a blue whale calf is the largest baby on earth: approximately 8m long and weighing about 4 tonnes. They grow at a rate of 90 kg per day and wean after 7-8 months, once they have reached about 15 m in length, and are able to follow the normal migration pattern alone. They reach sexual maturity at 5-10 years. This growth rate is astonishing and is probably the fastest in the animal kingdom.  From  conception to weaning, it represents a several billion-fold increase in tissue in just over a year and a half. Like other baleen whales, the blue whale has no teeth so it is hard to tell its age but scientists believe they live until at least 50.
Like other large whales, blue whales are threatened by chemical and sound pollution, habitat loss, overfishing of krill, ship strikes and becoming entangled in fishing gear. Climate change could also have a major impact on its food supply, since global warming and associated ocean acidification may impact krill populations. In addition, frontal zones - critical whale habitats - are projected to move further south due to climate change. Frontal zones are boundaries between different water masses, where water can rise from the depths, bringing with it large amounts of nutrients that stimulate the growth of phytoplankton and support substantial populations of prey species for whales. Blue whales would have to migrate further (perhaps 200-500 km more) to reach and feed at these food-rich areas where they build up reserves to sustain themselves for the rest of the year. These longer migration paths could increase the energy costs  of migration and reduce the duration of the main feeding season. As frontal zones move southward, they also move closer together, reducing the overall area of foraging habitat available.

Despite these drawbacks, (25) ______the retirement age is still considered by policymakers as one of the key solutions to the ageing population problem in Vietnam, But these are only temporary solutions. Complementary long-term solutions such as increasing labor productivity must also be examined.
As Vietnam has specialized in manufacturing with its competitive advantage of a cheap labor force in the global supply chain, (26)______higher education should be reoriented to focus more on vocational training rather than university degrees. The Vietnamese government has already taken action by simplifying the entrance exam to university. Previously, Vietnam's national entrance exam was very difficult and only a limited number of the most talented citizens managed to enter universities.
However, as living standards in Vietnam improve and more families can afford to send their children to university, universities have become more commercialized and entering university is no longer a rare achievement. The low quality of Vietnamese universities also means the majority of graduating students are unable to find an appropriate job. By simplifying entrance exams to deemphasize university degrees, the government has encouraged students to opt for vocational training.

Martin Luther King, Jf, is well- known for his work in civil rights and for his many famous speeches, among which is his moving “I have a dream” speech. But fewer people know much about King’s childhooD. M.L., as he was called, was bom in 1929 in Atlanta, Georgia, at the home of his maternal grandfather. M.L.’s grandfather purchased their home on Auburn Avenue in 1909, twenty years before M.L was bom. His grandfather allowed the house to be used as a meeting place for a number of organizations dedicated to the education and social advancement of blacks. M.L. grew up in the atmosphere, with his home being used as a community gathering place, and was no doubt influenced by it.

M.L.’s childhood was not especially eventfully. His father was a minister and his mother was a musician. He was the second of three children, and he attended all black schools in a black neighborhood. The neighborhood was not poor, however. Auburn Avenue was an area of banks, insurance companies, builders, jewelers, tailors, doctors, lawyers, and other businesses and services. Even in the face of Atlanta’s segregation, the district thrived. Dr. King never forgot the community spirit he had known as a child, nor did he forget the racial prejudice that was a huge barrier keeping black Atlantans from mingling with whites.

Dolphins are one of the most intelligent species on the planet, which makes them a very interesting animal to scientists. In their natural habitats, dolphins use various vocalization techniques. They whistle and squeak to recognize members of their pod, identify and protect their young, and call out warnings of danger. They also make clicking sounds used for echolocation to find food and obstacles in dark and murky waters.
Amazingly, the whistling sound that the bottlenose dolphin makes has been found to have a similar pattern to human language. They always make conversational sounds when they greet each other. If you listen to dolphins' squeaks and squeals, it will sound like they are having a conversation.
Dolphins usually use both sound and body language to communicate with each other. It is through gesture and body language, however, that most of their communication with humans comes. Dolphins can be trained to perform complicated tricks. This suggests they have a high level of intelligence and communication capacity. If they work for a long time with a trainer, they are able to recognize and understand human commands.
A lot of dolphin communication has been studied using dolphins in captive environments. These studies have been criticized because some marine biologists believe that dolphins living in aquariums or research centers cannot be considered "normal." Even so, most believe that studying dolphin communication in captivity is useful for beginning to understand the complexity of dolphin communication. After all, dolphins are one of the most intelligent animals. Their ability to communicate is impressive and worthy of study.

Scientists do not yet thoroughly understand just how the body of an individual becomes sensitive to  a substance that is harmless or even wholesome for the average person. Milk, wheat, and egg, for example, rank among the most healthful and widely used foods. Yet these foods can cause persons sensitive to them to suffer greatly. At first, the body of the individual is not harmed by coming into
contact with the substance. After a varying interval of time, usually longer than a few weeks, the body becomes sensitive to it, and an allergy has begun to develop. Sometimes it's hard to figure out if you have a food allergy, since it can show up so many different ways.
Your symptoms could be caused by many other problems. You may have rashes, hives, joint pains mimicking arthritis, headaches, irritability, or depression. The most common food allergies are to milk, eggs, seafood, wheat, nuts, seeds, chocolate, oranges, and tomatoes. Many of these allergies will not develop if these foods are not fed to an infant until her or his intestines mature at around seven months. Breast milk also tends to be protective. Migraines can be set off by foods containing tyramine, phenathylamine, monosodium glutamate, or sodium nitrate. Common foods which contain these are chocolate, aged cheeses, sour cream, red wine, pickled herring, chicken livers, avocados, ripe bananas, cured meats, many Oriental and prepared foods (read the labels!).
Some people have been successful in treating their migraines with supplements of B-vitamins, particularly B6 and niacin. Children who are hyperactive may benefit from eliminating food additives, especially colorings, and foods high in salicylates from their diets. A few of these are almonds, green peppers, peaches, tea, grapes. This is the diet made popular by Benjamin Feingold, who has written the book “Why your Child is Hyperactive”. Other researchers have had mixed results.

Which of the following was a suggested treatment for migraines in the passage?

Martin Luther King, Jf, is well- known for his work in civil rights and for his many famous speeches, among which is his moving “I have a dream” speech. But fewer people know much about King’s childhooD. M.L., as he was called, was bom in 1929 in Atlanta, Georgia, at the home of his maternal grandfather. M.L.’s grandfather purchased their home on Auburn Avenue in 1909, twenty years before M.L was bom. His grandfather allowed the house to be used as a meeting place for a number of organizations dedicated to the education and social advancement of blacks. M.L. grew up in the atmosphere, with his home being used as a community gathering place, and was no doubt influenced by it.
M.L.’s childhood was not especially eventfully. His father was a minister and his mother was a musician. He was the second of three children, and he attended all black schools in a black neighborhood. The neighborhood was not poor, however. Auburn Avenue was an area of banks, insurance companies, builders, jewelers, tailors, doctors, lawyers, and other businesses and services. Even in the face of Atlanta’s segregation, the district thrived. Dr. King never forgot the community spirit he had known as a child, nor did he forget the racial prejudice that was a huge barrier keeping black Atlantans from mingling with whites.

According to the author, M.L.     .

Astronomers have for the first time definitively ID’d the birth of a specific heavy element during a neutron-star smashup. They found strontium. And it showed up in the wavelengths of light — or spectra — making up this collision’s afterglow.
Scientists had assumed that a collision by two super-dense objects, such as neutron stars, would trigger a chain of nuclear reactions. They’re known as the r-process. In such an environment, the nuclei of atoms could rapidly gobble up neutrons. Afterward, those nuclei would become transformed in a process known as radioactive decay. The r-process was seen as a way to transform old, smaller elements into newer, bigger ones. About half of all elements heavier than iron were thought to be made in the r-process. Finding strontium in the recent collision at last offered the most direct evidence yet that neutron-star collisions really do trigger the r-process.
Physicists had long predicted that silver, gold and many other elements more massive than iron formed this way. But scientists weren’t sure where those r-process reactions took place. After all, no one had directly seen the r-process underway in a celestial event. Or they didn’t until the merger of two neutron stars in 2017. Scientists quickly analyzed light given off by that cataclysm. In it, they found evidence of the birth of a hodgepodge of heavy elements. All would seem to have come from the r-process. 
The researchers were examining mostly very heavy elements — ones whose complex atomic structures can generate millions of spectral features. And all of those features were not yet fully known, Watson points out. This made it extremely difficult to tease apart which elements were present, he says.
Strontium, however, is relatively light compared to other r-process elements. And its simple atomic structure creates a few strong and well-known spectral clues. So Watson and his colleagues expanded their analysis to consider it. In doing so, they turned up the clear "fingerprint" of strontium. It emerged in light collected by the Very Large Telescope in Chile within a few days of the neutron-star collision. Seeing strontium in the afterglow wasn’t all that unexpected, says Brian Metzger. He’s an astrophysicist at Columbia University in New York City and not involved in the new work. Strontium, he notes, “does tell us something interesting” about the elements formed during the neutron-star collision.

The word “tease” in paragraph 4 can be replaced by _______.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct word or phrase that best fits each of the numbered blanks. 

BRITPOP
       In the early to mid-1990s Britpop artists, influenced by British guitar sounds of the 1960s and 70s, wrote about topics that were considered purely British and relevant to their generation. The music style with its (1) ____ songs was considered as a reaction against the grunge music that was arriving from the States and, in fact, it did not have a huge commercial success in the USA.
       Britpop bands included Suede, Pulp, Blur and Oasis but it was the (2) ____ two that really dominated the market. In 1994 Blur released their album Parklife (3) ____ had a strong retro feel from the 70s and Oasis released Definitely Maybe, again with a retro feel reminiscent of John Lennon.
       The two bands were often seen (4) ____ rivals and this was exaggerated by the media who emphasized their differences in origins and class: Oasis from the north of England, Blur from the south. This culminated in both bands releasing singles on the same day in 1985, with Blur's single Country House reaching number one in the charts and Oasis's Roll With It number two. Oasis, however, went on to have greater commercial success, particularly with the album (What's the story) Morning Glory? (1985) which sold 412 million (5) ____ in the UK.
