Read the following passage and choose the best answer (A, B, C, D):
Paul Watson is an environmental activist. He is a man who believes that he must do something, not just talk about doing something. Paul believes in protecting endangered animals, and he protects them in controversial ways. Some people think that Watson is a hero and admire him very much. Other people think that he is a criminal. On July 16th, 1979, Paul Watson and his crew were on his ship, which is called the Sea Shepherd. Watson and the people who work on the Sea Shepherd were hunting on the Atlantic Ocean near Portugal. However, they had a strange prey, instead of hunting for animals, their prey was a ship, the Sierra. The Sea Shepherd found the Sierra, ran into it and sank it. As a result, the Sierra never returned to the sea. The Sea Shepherd, on the other hand, returned to its home in Canada. Paul Watson and his worked thought that they had been successful. The Sierra had been a whaling ship, which had operated illegally. The captain and the crew of the Sierra did not obey any of the international laws that restrict whaling. Instead, they killed as many whales as they could, quickly cut off the meat, and froze it. Later, they sold the whale meat in countries where it is eaten. Paul Watson tried to persuade the international whaling commission to stop the Sierra. However, the commission did very little, and Paul became impatient. He decided to stop the Sierra and whaling ships in any way that he could. He offered to pay $25,000 to an one who sank any illegal whaling ship, and he sank the Sierra. He acted because he believed that the whales must be protected. Still, he acted without the approval of the government; therefore, his action controversial. Paul Watson is not the only environmental activist. Other men and women are also fighting to protect the Earth. Like Paul Watson, they do not always have the approval of their governments, and like Watson, they have become impatient. Yet, because of their concern for the environment, they will act to protect it.

Over the past 600 years, English has grown from a language of few speakers to become the dominant language of international communication. English as we know it today emerged around 1350, after having incorporated many elements of French that were introduced following the Norman invasion of 1066. Until the 1600s, English was, for the most part, spoken only in England and had not extended even as far as Wales, Scotland or Ireland. However, during the course of the next two centuries, English began to spread around the globe as a result of exploration, trade (including slave trade), colonization, and missionary work. Thus, small enclaves of English speakers became established and grew in various parts of the world. As these communities proliferated, English gradually became the primary language of international business, banking and diplomacy.
Currently, about 80 percent of the information stored on computer systems worldwide is in English. Two-thirds of the world’s science writing is in English, and English is the main language of technology, advertising, media, international airports, and air traffic controllers. Today there are more than 700 million English users in the world, and over half of these are non-native speakers, constituting the largest number of non-native users than any other language in the world.

Which of the following is not mentioned as the field where English is the main language?

Read the following passage and choose the best answer (A, B, C, D):
From their inception, most rural neighborhoods in colonial North America included at least one carpenter, joiner, sawyer, and cooper in woodworking; a weaver and a tailor for clothing production; a tanner, currier, and cordwainer (shoemaker) for fabricating leather objects; and a blacksmith for metalwork. Where stone was the local building material, a mason was sure to appear on the list of people who paid taxes. With only an apprentice as an assistant, the rural artisan provided the neighborhood with common goods from furniture to shoes to farm equipment in exchange for cash or for “goods in kind” from the customer’s field, pasture, or dairy. Sometimes artisans transformed material provided by the customer wove cloth of yam spun at the farm from the wool of the family sheep; made chairs or tables from wood cut in the customer’s own woodlot; produced shoes or leather breeches from cow, deer, or sheepskin tanned on the farm.  Like their farming neighbors, rural artisans were part of an economy seen, by one historian, as “an orchestra conducted by nature.” Some tasks could not be done in the winter, others had to be put off during harvest time, and still others waited on raw materials that were only produced seasonally. As the days grew shorter, shop hours kept pace, since few artisans could afford enough artificial light to continue work when the sun went down.  To the best of their ability, colonial artisans tried to keep their shops as efficient as possible and to regularize their schedules and methods of production for the best return on their investment in time, tools, and materials. While it is pleasant to imagine a woodworker, for example, carefully matching lumber, joining a chest together without resort to nails or glue, and applying all thought and energy to carving beautiful designs on the finished piece, the time required was not justified unless the customer was willing to pay extra for the quality - and few in rural areas were. Artisans, therefore, often found it necessary to employ as many shortcuts and economics as possible while still producing satisfactory products.

Stonehenge, the prehistoric stone circle in southern England, is one of the most distinctive and mysterious monuments in the world. The monument, which attracted more than one and a half million visitors last year, is thought to be up to 5,000 years old, and the heaviest stone weighs 38 tons. No one really knows how the stones got there, or the reason they look the way they do – but a piece removed from one of the stones six decades ago could bring some answers. At first glance, the new “discovery” - a cylinder of rock - might look unremarkable. But for Lewis and Robin Phillips, it meant one thing: their dad, Robert. In 1958, Robert Phillips worked on a major restoration project commissioned by the British government. The goal was to make the monument safer, and help historians better understand what Stonehenge was and why it was there. The team drilled through the largest of the sarsen rocks, removing three stone cores. Robert Phillips was gifted one as a souvenir. At the time, the core sample was considered to be “waste material,” Lewis said. “I think that the standards of the day, in conservation, were a bit different to what they are now,” Robert added. Six decades later, Robert - who’s now in his 90s - asked his sons to return the “waste material.” But what had become a family heirloom for the Phillips’ was “the Holy Grail” of Stonehenge for geologists, according to Susan Greaney, an archaeologist at English Heritage. “When the Phillips family first got in touch with us, we had no idea that this existed,” Greaney said. “We’d just assumed that they’d been thrown away.” In 1958, samples like this couldn’t provide much information - but now, Greaney added, it can help archaeologists understand where the stones were from and how they were transported. It could even provide clues to one of the biggest questions: why move all these rocks to one location? Right now, “we don’t know” is the answer to that, Greaney said. "We think this is a prehistoric temple. It’s aligned with the movements of the sun, so we think it’s some kind of ceremonial space. But exactly what the stones mean, why they built them in this way and set them up in the way we see today, there are lots of mysteries about Stonehenge that we have yet to get to the bottom of.

Read the following passage and choose the best answer (A, B, C, D):
Geothermal energy is the heat from the Earth. It’s clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth’s surface, and down even deeper to the extremely high temperatures of molten rock called mác-ma. Almost everywhere, the shallow ground or upper 10 feet of the Earth’s surface maintains a nearly constant temperature between 50° and 60°F (10° and 16°C). Geothermal heat pumps can tap into this resource to heat and cool buildings. A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building. In the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system. In the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger. The heat removed from the indoor air during the summer can also be used to provide a free source of hot water. In the United States, most geothermal reservoirs of hot water are located in the western states, Alaska, and Hawaii. Wells can be drilled into underground reservoirs for the generation of electricity. Some geothermal power plants use the steam from a reservoir to power a turbine/generator, while others use the hot water to boil a working fluid that vaporizes and then turns a turbine. Hot water near the surface of Earth can be used directly for heat. Direct-use applications include heating buildings, growing plants in greenhouses, drying crops, heating water at fish farms, and several industrial processes such as pasteurizing milk. Hot dry rock resources occur at depths of 3 to 5 miles everywhere beneath the Earth’s surface and at lesser depths in certain areas. Access to these resources involves injecting cold water down one well, circulating it through hot fractured rock, and drawing off the heated water from another well. Currently, there are no commercial applications of this technology. Existing technology also does not yet allow recovery of heat directly from mác-ma, the very deep and most powerful resource of geothermal energy

Read the following passage and choose the best answer (A, B, C, D):
Sophia is a humanoid robot developed by Hong Kong-based company Hanson Robotics. She has been designed to learn and adapt to human behavior and work with humans, and has been interviewed around the world. In October 2017, she became a Saudi Arabian citizen, the first robot to receive citizenship of a country. According to herself, Sophia was activated on April 19, 2015. She is modeled after actress Audrey Hepbum,and is known for her human-like appearance and behavior compared to previous robotic variants. According to manufacturer, David Hanson, Sophia has artificial intelligence, visual data processing and facial recognition. Sophia also imitates human gestures and facial expressions and is able to answer certain questions and to make simple conversations on predefined topics (e.g. on the weather). The robot uses voice recognition technology from Alphabet Inc. (parent company of Google) and is designed to get smarter over time. Sophia’s intelligence software is designed by SingularityNET. The AI program analyses conversations and extracts data that allows her to improve responses in the future. It is conceptually similar to the computer program ELIZA, which was one of the first attempts at simulating a human conversation. Hanson designed Sophia to be a suitable companion for the elderly at nursing homes, or to help crowds at large events or parks. He hopes that she can ultimately interact with other humans sufficiently to gain social skills. Sophia has been interviewed in the same manner as a human, striking up conversations with hosts. Some replies have been nonsensical, while others have been impressive, such as lengthy discussions with Charlie Rose on 60 Minutes. In a piece for CNBC, when the interviewer expressed concerns about robot behavior, Sophia joked that he had “been reading too much Elon Musk, and watching too many Hollywood movies”. Musk tweeted that Sophia could watch The Godfather and suggested “What’s the worst that could happen?”. On October 11, 2017, Sophia was introduced to the United Nations with a brief conversation with the United Nations Deputy Secretary-General, Amina J. Mohammed. On October 25, at the Future Investment Summit in Riyadh, she was granted Saudi Arabian citizenship, becoming the first robot ever to have a nationality. This attracted controversy as some commentators wondered if this implied that Sophia could vote or marry, or whether a deliberate system shutdown could be considered murder. Social media users used Sophia’s citizenship to criticize Saudi Arabia’s human rights record.

Read the following passage and choose the best answer (A, B, C, D):
There is a new type of advertisement becoming increasingly common in newspaper classified columns. It is sometimes placed among “situations vacant”, although it does not offer anyone a job, and sometimes it appears “situations wanted”, although it is not placed by someone looking for a job, either. What it does is to offer help in applying for a job. “Contact us before writing your application”, or "Make use of our long experience in preparing your curriculum vitae or job history”, is how it is usually expressed. The growth and apparent success of such a specialized service is, of course, a reflection on the current high levels of unemployment. It is also an indication of the growing importance of the curriculum vitae (or job history), with the suggestion that it may now qualify as an art form in its own right. There was a time when job seekers simply wrote letters of application. “Just put down your name, address, age and whether you have passed any exams”, was about the average level of advice offered to young people applying for their first jobs when I left school. The letter was really just for openers, it was explained, everything else could and should be saved for the interview. And in those days of full employment, the technique worked. The letter proved that you could write and were available for work. Your eager face and intelligent replies did the rest. Later, as you moved up the ladder, something slightly more sophisticated was called for. The advice then was to put something in the letter which would distinguish you from the rest. It might be the aggressive approach. “Your search is over. I am the person you are looking for,” was a widely used trick that occasionally succeeded. Or it might be some special feature specially designed for the job in view

Spend just a minute watching the world population counter tick up on Worldometers and you’ll see just how quickly we’re swelling in numbers. The current figure stands at around 7.7 billion, and this is projected to become 9.8 billion by 2050, according to the UN. More people means more carbon footprints - more cars, waste and emissions, more houses and infrastructure to be constructed using the world’s limited resources, more mouths to be fed using more water and energy in food production. Governments recognise the severity of the situation and have mostly come together over global policies like the UN’s Paris Agreement, to limit carbon emissions and their impact on climate change. In addition, new technologies are being developed to make our use of resources more efficient. As for controlling population growth, the education of women is one key factor. Research shows the higher level to which a woman is educated, the fewer children she is likely to have. In Ghana, for example, women who have been to high school, have a fertility rate of between two and three children, compared with six for those who have no education. This could be for several reasons including learning about desired family size and understanding child health better. This means that the mother is more confident her children will survive. She is also likely to hold more sway within the family, arguing for fewer children if that is what she wants.  There is also plenty that individuals can do to reduce their personal footprint. Earth Overshoot Day is defined as the day when humanity has used up nature’s resource budget for the year. The Global Footprint Network calculates that moving Earth Overshoot day back by five days every year would mean that, by 2050, we’d be using the resources of less than one planet. Just eating 50% less meat and replacing it with vegetarian alternatives could save the planet five days. As David Attenborough says, if we want to save Earth, we can no longer afford to keep eating meat: “We are omnivores, so biologically, if you could have a biological morality, you can say, yes we evolved to eat pretty well everything. But now we’ve got to a stage in our own social evolution in which that is no longer practical.” Sir David says he himself now eats less meat and is bolstered by the knowledge that it’s helping the planet.  
7. Which of the following statements is TRUE, according to the passage?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the following questions:
The United States Department of Education describes “giftedness” as exceptionally advanced performance or the potential for outstanding performance in intellectual, creative leadership, artistic, or specific academic fields. Children who demonstrate outstanding talents come from all social, cultural, and economic groups.
Educators believe that gifted students require special education services because their learning needs differ significantly from those of the general population. They learn more rapidly and are able to understand more abstract and complex ideas. They are also able to transform existing knowledge into new and useful forms, and to create new knowledge recognized for its originality, complexity, and elegance. Special education services and facilities for gifted children may enhance these abilities. In addition, some gifted learners may require special counseling services to address social or emotional adjustment issues that are complicated by their exceptional abilities.
Many regular elementary and secondary schools in the United States offer special programs designed specifically to meet the needs of gifted students. Some schools provide specialized education programs to gifted children exclusively. These schools offer advanced education in mathematics, science, technology, the arts, or other academic disciplines. Many schools rely on intelligence tests to identify gifted students. However, most guidelines for determining giftedness recommend the use of a combination of standardized test scores, rating systems developed by individual schools, classroom observation records, and performance assessments.
Gifted children may study a specially modified curriculum or may progress through academic subjects at an accelerated pace. Acceleration involves adapting education programs so that students may progress through particular subject material quicker than usual. These modifications may take place within the regular classroom setting or they may involve changing the child’s placement in school. Some gifted children gain early entrance to kindergarten, skip grades, enter college earlier than usual, or take specific courses with older children. Ideal programs for gifted students consider the individual needs of children and offer multiple options for services. These programs generally involve both advanced course materials and acceleration.

These days, most people in Britain and the US do not wear very formal clothes. But sometimes it is important to wear the right thing.
Many British people don't think about clothes very much. They just like to be comfortable. When they go out to enjoy themselves, they can wear almost anything. At theatres, cinemas and concerts you can put on what you like from elegant suits and dresses to jeans and sweaters. Anything goes, as long as you look clean and tidy.

But in Britain, as well as in the US, men in offices usually wear suits and ties, and women wear dresses or skirts (not trousers). Doctors, lawyers and business people wear quite formal clothes. And in some hotels and restaurants men have to wear ties and women wear smart dresses.
In many years, Americans are more relaxed than British people, but they are more careful with their clothes. At home, or on holiday, most Americans wear informal or sporty clothes. But when they go out in the evening, they like to look elegant. In good hotels and restaurants, men have to wear jackets and ties, and women wear pretty clothes and smart hairstyles.
It is difficult to say exactly what people wear informal or formal in Britain and the US, because everyone is different. If you are not sure what to wear, watch what other people do and then do the same. You'll feel more relaxed if you don't look too different from everyone else.

Who doesn’t usually wear suits and ties?

The generation gap (1)_____ to the difference in attitudes or behavior between a  younger generation and the older one. In my opinion, different attitudes towards life, different views about certain problems, and a lack of communication can cause a generation gap in most societies.  The first factor is that parents and children generally see things from different (2)______. Choosing a career is a good example for this. Many parents try to impose certain careers they favor (3)_____ their children, based on their own perceptions. However, young people don’t always understand their parents’ points of views. Instead, they prefer to be free to make their own decisions on their future career. Another factor lies in differences in musical tastes, fashion, and political views between young people and their parents. (4)______, having a pierced nose might be viewed as fashionable by some teens, but for many parents, it is considered to be an act of rebellion against social norms.  The major factor (5)____ the generation gap is lack of communication between parents and their children. Parents tend to be dominant and not to trust their children to deal with crises. Also, they keep talking too much about certain problems. That is the reason why young people seldom reveal their feelings to their parents. When facing problems, young people prefer to seek help from their classmates or friends

Print media encompasses mass communication through printed material. It includes newspapers, magazines, booklets and brochures, house magazines, periodicals or newsletters, direct mailers, handbills or flyers, billboards, press releases, and books. Newspapers enjoyed the position of the most preferred medium to reach a wider audience until electronic communication emerged on the media scene. In the early days, newspapers were the only medium that masses at large depended on, for daily news. A newspaper carries all kinds of communication related to a variety of topics like politics, socialism, current affairs, entertainment, finance, stocks, etc. Apart from this, it also includes topics, which are in lighter vein like cartoons, movie reviews, book reviews, puzzles, crosswords, etc. This captivates the imagination and interests of readers from all age groups. Newspapers are an important platform of mass communication, as they reach every nook and corner of the world where electronic media fails to reach. It plays a pivotal role in providing authentic firsthand information, building opinions, updating the knowledge of the reader, and serves as a good platform for advertisers to promote their products. However, with the emergence of Internet, which updates information every second, and is just a click away, the popularity of newspapers has reduced. Magazines are another type of popular culture print media. They usually cater to a specific type of audience who are looking for information based on a particular subject. Magazines cover a plethora of topics, like current affairs, business, finance, consumers, gadgets, self-help, luxury, lifestyle, beauty, fashion, entertainment, travel, etc. Magazines like TIME and Reader’s Digest include information, which is all-pervasive. The frequency of magazines can be weekly, fortnightly, bi-monthly, quarterly, halfyearly, or yearly. These magazines are the best forum for advertisers, as they have a niche  readership. The readers look for a specific type of information, say for example, a camera ad in a Gadget magazine will definitely have a direct brand impact on the reader who wants to buy a camera. Also, the shelf life and brand recall of magazines is far better than newspapers, which have a short life span.

For many years, scientists have speculated that the cataclysmic impact of an asteroid with the earth was responsible for the demise of the dinosaurs approximately 65 million years ago. Previous discoveries and results have hinted that an asteroid two kilometers in diameter struck the Yucatan peninsula in Eastern Mexico. This impact, stronger than one thousand nuclear explosions, is speculated to have cast a cloud of dust and debris into the atmosphere, covering the entire surface of the earth and blocking out the sun and consequently lowering the surface temperature of the earth. With such a radical change in the earth's environment, scientists believe that over 99% of all animal and plant species were eradicated. Only after millions of years did plants and animals even begin to recover and develop into forms that were better adapted to survive changes in their environment. But, the reign of the dinosaurs had ended and the age of mammals had begun. The crucial link that has held this theory together has been the element iridium. Iridium is not commonly found on either the surface of the earth or inside the crust. It is more commonly found in asteroids or meteorites throughout the solar system. Scientists have hypothesized that after the asteroid impacted the Earth, an even layer of iridium sediment settled over the globe and eventually became part of its surface. The theory, of course, has depended on the discovery of such an existing layer of iridium. Unfortunately, scientists have never been able to offer absolute proof that this asteroid impact ever occurred. Recently, however, a discovery may go a long way toward validating these scientists 'theories. In 1996, a team of marine biologists excavated samples of rock from the Atlantic Ocean just off the cost of Bermuda. Found thousands of meters below the sea, these samples contain iridium similar to those found in the Yucatan peninsula thousands of kilometers away. At first, scientists were skeptical whether the samples were from the same time period. But since carbon dating placed them to 65 million years ago, their doubts were quickly alleviated. Since then many of the other theories for the demise of the dinosaur have been finally laid to rest.

Read the following passage and choose the best answer (A, B, C, D):
In addition to improved physical health, sport plays a primarily positive role in youth  development, including improved academic achievement, higher self-esteem, fewer behavioral problems, and better psychosocial development. Many studies focus on the effects of sport on the five “C’s” - competence, confidence, connections, character, and caring. The many facets of playing sport - the discipline of training, learning teamwork, following the leadership of coaches and captains, learning to lose - provide lifelong skills for athletes.  The literature on youth sport stresses the positive effects of participation in learning the important life skills of goal setting and time management combined with enjoyment; the development of a strong sense of morality; and the development of an appreciation of diversity. Studies have shown that children and youth participating in sport, when compared to peers who do not play sport, exhibit higher grades, expectations, and attainment; greater personal confidence and self-esteem; greater connections with school – that is, greater attachment and support from adults; stronger peer relationships, more academically oriented friends, greater family attachment and more frequent interactions with parents; more restraint in avoiding risky behavior; and greater involvement in volunteer work.  Sport provides opportunities for children and youth to engage in valuable and positive relationships with adults. Thus, it is a missed opportunity for children who are "gated" - or not included in sport - during early stages of childhood because they are less well behaved than other children. These children are being prevented from participating in the very thing that could help them learn to control and regulate their behavior. Sport provides an opportunity for children to safely navigate and negotiate between right and wrong as they learn to interact with peers and adults. Research by Taliaferro et al. suggests that playing sport can even protect against suicide risk in youth. Compared to non-athletes, male athletes exhibit lower levels of hopelessness and suicidal ideation. Young males involved in multiple sports seem to garner even more protection in this regard. Similar results were found for girls. Research on the role of exercise in adults confirms that it improves mood and alleviates many forms of depression. Bartko and Eccles les found that youth who are highly involved in sport are more “psychologically resilient,” that is, better able to recover from problems. Eccles et al. found that sport participation protects young athletes against social isolation

Read the following passage and choose the best answer (A, B, C, D):
We’re all born with a passion for learning that for many of us sadly fades over time. A mindset of continuous learning best positions us for an ever-evolving future. Dr. Carol Dweck, a psychologist and Stanford professor, distinguishes between a fixed mindset and a growth mindset. In a fixed mindset, people believe that their basic qualities, like intelligence or talent, are fixed traits. They believe that talent alone, without effort, creates success. They believe that they are “smart” or “dumb” and that there is no way to change. No matter how hard they work at something, a ceiling prevents them from getting better. In a growth mindset, people believe that their basic abilities can be developed through dedication and hard work. Brains and talent are a starting point. This view creates a love of learning and a resilience that is essential for great accomplishments. The sky is the limit. It’s not about proving yourself, it’s about improving yourself. “Future Shock” author Alvin Toffler once said, “The illiterate of the 21st century will not be those who cannot read and write, but those who cannot learn, unlearn and relearn.” Learning and relearning can be fun. Unlearning is hard. It’s hard discarding old thinking, protocols, treatment plans, business practices and communication styles. But that hard work is necessary to progress and grow as people and professionals. Unlearning is particularly difficult for adults; kids are good at it. Our thinking becomes more rigid as we age. How difficult was it for medical professionals of the past to unlearn bloodletting, lobotomies, arsenic and mercury treatments, urine for teeth whitening, shock therapy, and heroin for children’s coughs? All were considered contemporary medicine in our great-grandparents’ day. The importance of learning, unlearning and relearning has never been more important than in today’s rapidly changing workplace
