Read the following passage and choose the best answer (A, B, C, D):
Some cities are located by chance. A wagon breaks down, the driver spends some  time in repairs, finds that he is in a congenial spot, and settles down. Later another person builds a house near his, and later someone adds an inn. Someone else starts selling farm produce there. Soon there is a little market, which grows to a town, and later to a city.  Other places were destined by nature to become cities. London, for example, is on what is called the head of navigation - the point where it becomes too difficult for oceangoing ships to continue upriver, and must transfer their cargoes. As with London, the head of navigation is also the point where the river can be conveniently bridged. In fact, the location of a bridge is often the reason for the birth of a town - as Cambridge or Weybridge in England show. Again, a good harbour will generally lead to a city growing up about it. New York and San Francisco began life as ports, as did Cape Town in South Africa. Some places were created mainly for military purposes, such as Milan, and the host of English cities finishing with - cester, which is derived from castra which means camp in Latin. Chester itself, created to guard the Welsh border, is a very good example. Other such military bases are Manchester, Doncaster, and of course, Newcastle.  A few cites are not created by accident, but by intention. This was the case with Milton Keynes in England, but the most famous examples of such cities are capitals. Brasilia, Canberra and Washington are capitals created in modern times, but even their greatest admirers will admit that they lack a certain character. It is no co-incidence that there are famous pop songs about New York, (“New York, New York”) Chicago (“My kind of Town”) San Francisco (“Going to San Francisco”) and many other US cities, but none about the nation’s capital. On the other hand any Londoner can give you at least three songs about the place.

Read the following passage and choose the best answer (A, B, C, D):
Human’s avarice for ivory has resulted in thousands of unfathomable elephant atrocities and senseless suffering that has pushed the species to the brink of extinction. In 2015, the U.S. and China announced they will work together to enact a near complete ban on the import and export of ivory. As an industry that has largely been driven by China and, if substantiated, these claims could be a ray of light for one of the most endangered animals in the kingdom. However, as the famous saying goes, “for every action, there is an equal and opposite reaction.” With the worldwide attention on elephant ivory, hippo teeth, which can grow up to three-feet-long, have become the next target. Since the United Nations Convention on International Trade in Endangered Species officially imposed a ban on ivory trading in 1990, about 30,000 pounds per year of hippo teeth have been exported from Africa. On a recent trip to Kenya, I had the unfortunate displeasure of meeting these facts face-to-face. On the banks of the Mara River, the infamous transient point of the great wildebeest migration, I met a Conservancy Ranger, a local Kenyan, named Ivan. He led me along a narrow path above the riverbed to view pods of hippos. They clumped together in the river, every few minutes lifting their heads above the waterline to welcome my arrival. Despite their label as one of the most dangerous animals in Africa, they were playful to watch. Their tiny ears and eyes would appear from the murky river and then, with a splash, they would disappear. The river is everything to the hippo, Ivan explained, it is their lifeline. The only real time they leave the river is during their nightly ritual of traveling to nearby plains to consume grasses. Contrary to their aggressiveness, they are vegetarians. As we neared the end of our trek, we reached the Mara Bridge, spanning the divide between Kenya and Tanzania. An undeniable stench filled the air. Our gaze fell to the water beneath the structure, and as if to mark the metaphorical significance of the passage, lay a poached hippo. It had been killed the previous night, probably as it grazed unsuspectingly under the cover of darkness. They had found spear punctures in its body, and its teeth were missing. It had somehow, in unthinkable pain, made its way back to the river, its home, to die.
2. What does the first paragraph mainly discuss?

Read the following passage and choose the best answer (A, B, C, D):
My mom is a pretty talented pianist. She reads music very well and loves to play  Chopin and various other classical artists. One of my earliest memories involves sitting under her piano bench while she played. It gave her a lot of joy and a lot of personal pride, I think. I trust that she naturally wanted those things for me when she enrolled me in piano lessons when I was about seven years old.  I hated them. I was scared of my teacher. I hated practicing. I hated the songs I was being forced to learn. I hated reading music. I was a young kid, and there were other things I wanted to do instead. It just didn’t interest me, and no amount of begging and pleading on my mother’s part could get me to enjoy practicing. One thing in particular that she used to say as she was begging me to practice was, “One day, when you’re older, you will cherish the ability to sit down and play.” Nevertheless, after a couple years of once-a-week torture, she finally allowed me to quit.  Years went by. I switched schools when I was 11 years old, got a new best friend, and got interested in music. This was a critical turning point. My best friend loved the band Bush and lots of other alternative bands of the ‘90s, and listening to them unlocked a whole new sonic world for me. I fell in love, fell completely and totally in love, with rock music.  My friend taught me the form for a power chord on her acoustic guitar. If you know how to play a power chord, you can play or at least convincingly fake pretty much every single rock song in the world. It was like someone had given me my first hit of a powerful opiate.  I spent hours practicing in my room. Hours sounding out my favourite songs. More hours playing along with those songs in front of my mirror, pretending I was Scott Weiland, Dolores O’Riordan, Chris Cornell, or my personal favourite Louise Post (of Veruca Salt). I unlocked a talent within myself that had gone obscenely undiscovered and undeveloped when I was a young child banging my head against a piano keyboard, trying and failing to read a piece of music - I could play the guitar by ear. I just hadn’t had the time to figure that out because my mom was trying so hard to get me to do something that did not come naturally to me and that I had no desire to do.

Read the following passage and choose the best answer (A, B, C, D):
Bagpipe music played, wreaths were sent and Amazing Grace was sung. A  black shroud was laid upon a makeshift urn. It was a funeral, of course, for which such displays of respect are common. But in this case, the people living in a small Nova Scotia community had gathered to pay their respects not to a person who had died, but to a post office.  The grief might have been hard for outsiders to understand, but not for those living in Head of St. Margaret’s Bay, N.S., where the post office run by Verna Dunlop was a big part of their small, tight-knit community. The post office, which had been located in the back of Dunlop’s home, was not just a utilitarian service kiosk where residents had to go to pick up their mail. According to locals, it was also a community hub where people gathered to catch up on the town gossip, or to enjoy a cup of the coffee the postmaster had been brewing for them. “It’s really the centre of the village,” said one woman, explaining what the post office meant to the people living there.  There had been a post office located in Head of St. Margaret’s Bay since before Confederation. And local residents spent months fighting to keep the one they had. But Canada Post made the decision to close it, as it was losing money. It was replacing the post office with sets of newly installed super mailboxes.  Many people in town weren’t convinced the coming changes were for the better. “We do not want those super mailboxes. We want to have a community life,” he said. At the mock funeral, Dunlop choked up as she said she hoped “this is going to stop,” alluding to the fact that it wasn’t just Head of St. Margaret’s Bay that was losing its post office. “We hope that the way of life that we’re used to we can keep,” she added. Canada Post had closed 40 such rural post offices that year and had long-term plans to close more than 5,000 of them across the country. “Just as Verna Dunlop’s post office came to symbolize for these people the best qualities of rural life, so does its passing remind them of the steady erosion of that way of life,” said Evans.

Read the following passage and choose the best answer (A, B, C, D):
Kids can be creatures of habit. Much like how they can watch the same movie over and over, some kids will stick to one author or genre of book that they’ve fallen in love with. But does it matter if they’re always reading the same type of book? After all, isn’t their love of reading in itself enough? Reading builds their imagination, develops their critical thinking skills, and improves their communication skills, amongst many other benefits. Well, while a love of reading of any sort is to be nurtured, when a child only reads the same author or type of book, their growth and the benefits they gain may not be as broad if they were to explore more types of books. Coaxing them to open up to reading other genres can be a big advantage for them in the long term. They will get exposed to different types of characters and lifestyles when they read a wider range of writing. For example, their favourite fantasy novels may spark their imagination, but true tales of life halfway around the world can trigger interest in traveling and foster understanding of other cultures. It helps them develop a broad perspective on the world around them. Their vocabulary will benefit, too, if they read a wide selection of books. Think of the words and the sentence structure used in a vampire book and how they will differ significantly from those in a suspense novel. They will have to sound out words, and it’ll be helpful to have a dictionary handy. With each new word encountered in the broad range of reading materials they’re consuming, their vocabulary grows. Reading a variety of books will also help your child grow their love of reading and it’ll fuel their motivation to read more and more. They once only adored one author, who has  a limited number of books written, discovering new authors or types of books expands their choice of reading material; they’ll never run out of books to add to their reading list! Consider, too, the value of specific types of books for very young readers. Ones that teach the alphabet help them learn that letters come together to form the words in books. Poetry with rhyming words will help develop a child’s phonemic awareness, which is the ability to hear, identify and manipulate individual sounds in spoken words. Folktales and nursery rhymes are beloved and cherished. Surely there are ones that bring you right back to your childhood, and they tend to be shared from one generation to the next - your child’s favourite will likely be ones they teach their children when they grow up and have kids of their own!

Alexander Hamilton was born on January 11, 1755 or 1757 in the West Indies. Due to his mother’s lack of marital status, Hamilton was not seen as a legitimate child and was thus denied access to church schools. When his mother died he was adopted by a merchant in Nevis, where he worked as a clerk. During his time in Nevis, Hamilton continued to write; one of his essays impressed the community leaders so much that they worked together and collected funds to send Hamilton to the colonies. Hamilton served in the revolutionary war, during which time he worked his way through battles and earned himself a place aiding General Washington. After the war, Hamilton was elected into the Congress of the Confederation. He was dissatisfied with the decentralized government that was set up and the inability to raise money from the states to pay the soldiers. Hamilton was involved in the Constitution Convention but did not fully agree with the document; despite his disagreements, he promoted the document because he believed it was a vast improvement over the Articles of Confederation. He pushed the ratification of the Constitution, teaming up with John Jay and James Madison to write the Federalist papers, which were often cited when pushing for the Constitution’s ratification. Alexander Hamilton was appointed as the country’s first Secretary of The Treasury on September 11, 1789. During his time as Secretary of the Treasury Hamilton helped write economic policies, develop the funding of state debts, establish the national bank, create a national currency, a system of tariffs, and a peaceful trade relationship with Britain. After his time in politics finished, Alexander Hamilton went back to New York to practice law. He died in a duel with Aaron Burr in Weehawken, New Jersey on July 12, 1804

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.

Read the following passage and choose the best answer (A, B, C, D):
By the end of the third millennium, people will all have access to basic utilities like  electricity and the internet. As a type of civilization, the overall energy consumption of everyone in the 30th century will be at a level of around 4×10²⁶ watts. In other words, the  energy utilization in a world full of working class consumers will be comparable to the luminosity of our parent star. So, the people of the future will inevitably need to fully harness the output of the Sun through the use of a vast array of satellite mega-structures that encircle the celestial body and capture the radiation it emits.  In requiring everyone to work together, the inclusive attitude of the future will cause everyone to grow much closer to one another, improving interpersonal relationships in neighborhoods the world over. By the year 3000, the whole of humanity will become a sort of poly-amorous society of mono-ethnic global citizens, living in a complex egalitarian intercontinental cooperative. Everyone will be part of multicultural communities within communities. Companies and credit unions will even be owned by their employees. People will all be very conscientious. Everyone will support the global economy, as well as ecology, of the world.  Humans will inhabit artificial urban jungles filled with buildings and sidewalks, while the other animals will inhabit natural rural jungles filled with wilderness and trails. Friends will walk through the crowded streets of the mega-cities of the future holding hands with one another. Public displays of affection will be customary among everyone. Casual bisexual encounters will be the norm. Everyone will care about everyone else. People will all accept each other, and help each other out, more and more as time goes on. The point is that eventually, everyone will finally get along. Humanity will progress to a point of collective compatibility as everyone sufficiently integrates and assimilates. From now until the year 3000, the several thousand languages currently spoken will reduce down to only about a hundred. More importantly, the nation-state members of the UN will all use the same form of electronic currency. As the countries of the world unify more and more, the metric system will become the universal standard of measurement. Things will become increasingly more common among everyone. This will bring everyone closer and closer together, each step of the way. In the end, cultural memes will all eventually just blend together in the great melting pot that is the world.  People will also change physically, along with mentally, too though. For instance, there will be an increase in both height and longevity, among people in general. In the year 3000 people will be about six feet tall, and live to be 120 years old, on average. They will experience a slight reduction in the size of their mouths, too. Improvements in nutritional science will revolutionize the world of medicine and alter the course of human evolution. Everyone will be genetically screened as an embryo to weed out defects and correct mistakes in their personal genome. 8th scale transhuman cyborgs will even go so far as to have 7 th  scale robotic integrations, with microscopic machines making them better. This will be terribly important because there will be very little diversity in the gene pool of the superhumans of the future, who are all bred to be what is considered ideal.

Read the following passage and choose the best answer (A, B, C, D):
The International Monetary Fund (IMF) is an organization of 189 member countries.  It stabilizes the global economy in three ways. First, it monitors global conditions and identifies risks. Second, it advises its members on how to improve their economies. Third, it provides technical assistance and short-term loans to prevent financial crises. The IMF’s goal is to prevent these disasters by guiding its members. These countries are willing to give up some of their sovereign authority to achieve that aim.  The IMF has the rare ability to look into and review the economies of all its member countries. As a result, it has its finger on the pulse of the global economy better than any other organization. The IMF produces a wealth of analytical reports. It provides the World Economic Outlook, the Global Financial Stability Report, and the Fiscal Monitor each year. It also delves into regional and country-specific assessments. It uses this information to determine which countries need to improve their policies. Hence, the IMF can identify which countries threaten global stability. The member countries have agreed to listen to the IMF’s recommendations because they want to improve their economies and remove these threats.  Since the Mexican peso crisis of 1994–95 and the Asian crisis of 1997–98, the IMF has taken a more active role to help countries prevent financial crises. It develops standards that its members should follow. For example, members agree to provide adequate foreign exchange reserves in good times. That helps them increase spending to boost their economies during recessions. The IMF reports on members countries’ observance of these standards. It also issues member country reports that investors use to make well-informed decisions. That improves the functioning of financial markets. The IMF also encourages sustained growth and high living standards, which is the best way to reduce members’ vulnerability to crises.  The IMF provides loans to help its members tackle balance of payments problems, stabilize their economies, and restore sustainable growth. Because the Fund lends money, it’s often confused with the World Bank. The World Bank lends money to developing countries for specific projects that will fight poverty. Unlike the World Bank and other development agencies, the IMF does not finance projects. Traditionally, most IMF borrowers were developing countries. They had limited access to international capital markets due to their economic difficulties. An IMF loan signals that a country’s economic policies are on the right track. That reassures investors and acts as a catalyst for attracting funds from other sources. All that shifted in 2010 when the Eurozone crisis prompted the IMF to provide short-term loans to bail out Greece. That was within the IMF’s charter because it prevented a global economic crisis.  The role of the IMF has increased since the onset of the 2008 global financial crisis. In fact, an IMF surveillance report warned about the economic crisis but was ignored. As a result, the IMF has been called upon more and more to provide global economic surveillance. It’s in the best position to do so because it requires members to subject their economic policies to IMF scrutiny. Member countries are also committed to pursuing policies that are conducive to reasonable price stability, and they agree to avoid manipulating exchange rates for unfair competitive advantage.

Human beings are plagued by all kinds of diseases and millions of people die from them. Many of these diseases such as diabetes, polio, whooping cough and diphtheria can be fatal and in the past, people used to die from them. However, with modern technology and a lot of research, scientists and doctors have come up with various ways to cure these diseases, and consequently, many lives are saved. In doing the medical research, doctors have come face to face with many problems. One such problem is the opposition that comes from animal activists. They are against the inhuman treatment of animals. They argue that in conducting their medical research, doctors put animals through a very painful process and this should be stopped. According to the fiercest animal activists, nothing justifies the use of animals in medical experiments, even if lives might be saved. To get their message across, animal activists are even willing to resort to the use of violence. Many animal protection groups, like the Animal Liberation Front (ALF), have broken into laboratories illegally to ‘rescue’ animals. They take away whatever animals they can find and free them. These people also make their case by threatening the researchers. They vandalize medical equipment, and in the most serious cases, they even . In stealing the animals, the activists are actually hindering the progress of medicine. In many cases, the animals were part of research for the cure for various diseases and visual defects in babies. Cures for problems that people face, therefore, come slower and in the waiting period, more people die. Researchers have come up with many cures in the process of working with animals and on animals. Organ transplants are so common today, but we forget that they became only  possible after they were tested on animals. Doctors were able to come up with a cure for river blindness, a disease that affects millions of people in South America and Africa. These are only a few examples, and there are many more. In spite of what animal activists think, most researchers do not treat animals cruelly. In fact, mistreated animals which are in agony will affect the quality of research so that results obtained are not really reliable. Thus, researchers do try to treat animals as well as possible. In the long run, animal activists can cause serious damage to the future of medicine. With their persistent campaigning, much of the public supports their cause. People with AIDS or cancer need doctors to do research to save their lives, and often it is a case where animal research is crucial before any cure can be found

Seeing the glass as half full may mean a longer life, according to research suggesting that optimists not only live longer in general, but have a better chance of reaching 85 or older. People of an upbeat disposition have previously been found to have a lower risk of heart conditions and premature death. Researchers now say it could also play a role in living a long life. “A lot of evidence suggests that exceptional longevity is usually accompanied by a longer span of good health and living without disability, so our findings raise an exciting possibility that we may be able to promote healthy and resilient ageing by cultivating psychosocial assets such as optimism,” said Lewina Lee, the lead author of the study at Boston University School of Medicine. Writing in the Proceedings of the National Academy of Sciences, Lee and colleagues report how they analysed data from two previous long-term research projects, one involving female nurses and the other focused on a cohort of men. The former team compared lifespan for the most optimistic with the least, taking into account factors including age, sex, race, education, depression and other health conditions present at the outset. The results show the most optimistic group of women had a lifespan almost 15% longer than the least. As for the other project, when the team compared the fifth of men boasting the highest optimism scores with the least optimistic, they found the most positive men had lifespans almost 11% longer. But being optimistic was not only linked to a longer lifespan. For men and women it was also linked more specifically to living to 85 or older when health behaviours were taken into account, with the most optimistic group of women having 20% better odds of reaching age 85 than the least. Lee said it was not yet clear why optimism is linked to longevity. “In our study, healthier behaviours, fewer depressive symptoms, and more social ties only partially accounted for the association from optimism to exceptional longevity,” Lee said, adding there are likely to be other mechanisms at play, such as optimistic people coping better with stress. Dr Catherine Hurt, an expert in health psychology at City, University of London, said the study highlighted the importance of psychological wellbeing alongside physical wellbeing for living a long and healthy life.

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:
After two decades of growing student enrollments and economic prosperity, business schools in the United States have started to face harder times. Only Harvard's MBA School has shown a substantial increase in enrollment in recent years. Both Princeton and Stanford have seen decreases in their enrollments. Since 1990, the number of people receiving Masters in Business Administration (MBA) degrees, has dropped about 3 percent to 75,000, and the trend of lower enrollment rates is expected to continue.
There are two factors causing this decrease in students seeking an MBA degree. The first one is that many graduates of four-year colleges are finding that an MBA degree does not guarantee a plush job on Wall Street, or in other financial districts of major American cities. Many of the entry-level management jobs are going to students graduating with Master of Arts degrees in English and the humanities as well as those holding MBA degrees. Students have asked the question, "Is an MBA degree really what I need to be best prepared for getting a good job?" The second major factor has been the cutting of American payrolls and the lower number of entry-level jobs being offered. Business needs are changing, and MBA schools are struggling to meet the new demands.

Rachel Carson was born in 1907 in Springdale, Pennsylvania. She studied biology in college and zoology at Johns Hopkins University, where she received her master's degree in 1933. In 1936, she was hired by the US Fish and wildlife service, where she worked most of her life. Carson's first book, Under the Sea Wind, was published in 1941. It received excellent reviews, but sales were poor until it was reissued in 1952. In that year, she published The Sea Around Us, which provided a fascinating look beneath the ocean's surface, emphasizing human history as well as geology and marine biology. Her language had a poetic quality. Carson consulted no less than 1,000 printed sources. She had voluminous correspondence and frequent discussions with experts in the field. However, she always realized the limitations of her non-technical readers. In 1962, Carson published Silence Spring, a book that sparked considerable controversy. It proved how much harm was done by the uncontrolled, reckless use of insecticides. She detailed how they poison the food supply of animals, kill birds, and contaminate human food. At that time, spokes men for the chemical industry mounted personal attacks against Carson and issued propaganda to indicate that her findings were flawed. However, her work was vindicated by a 1963 report of the President's Science Advisory Committee.
