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:
By mid-century, there will likely be 9 billion people on the planet, consuming ever more resources and leading ever more technologically complex lives. What will our cities be like? How much will artificial intelligence advance? Will global warming trigger catastrophic changes, or will we be able to engineer our way out of the climate change crisis?
Making predictions is, by nature, a dicey business, but to celebrate the 40th anniversary of Smithsonian magazine Big Think asked top minds from a variety of fields to weigh in on what the future holds 40 years from now. The result is our latest special series, Life in 20 50. Demographic changes in world population and population growth will certainly be dramatic. Rockefeller University mathematical biologist Joel Cohen says it's likely that by 2050 the majority of the people in the world will live in urban areas, and will have a significantly higher average age than people today. Cities theorist Richard Florida thinks urbanization trends will reinvent the education system of the United States, making our economy less real estate driven and erasing the divisions between home and work.
Large migrations from developing countries like Indonesia, Malaysia, Bangladesh, Mexico, and countries in the Middle East could disrupt western governments and harm the unity of France, Germany, Spain, the Netherlands, Poland, and the United Kingdom under the umbrella of the European Union.
And rapidly advancing technology will continue ever more rapidly. According to Bill Mitchell, the late director of MIT's Smart Cities research group, cities of the future won't look like "some sort of science -fiction fantasy" or "Star Trek" but it's likely that "discreet, unobtrusive" technological advances and information overlays, i.e. virtual reality and augmented reality, will change how we live in significant ways. Self-driving cars will make the roads safer, driving more efficient, and provide faster transports. A larger version of driverless cars-driverless trucks-may make long haul drivers obsolete.
Meanwhile, the Internet will continue to radically transform media, destroying the traditional model of what a news organization is, says author and former New York Times Public Editor, Daniel Okrent, who believes the most common kinds of news organizations in the future will be "individuals and small alliances of individuals” reporting and publishing on niche topics.

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:
Homeopathy, the alternative therapy created in 1796 by Samuel Hahnemann, and now widely used all over the world, is based on the belief that the body can be stimulated to heal itself. A central principle of the “treatment” is that “like cures like”, meaning a subtance that causes certain symptoms can also help to remove those symptoms. Medicines used in homeopathy are created by heavily diluting in water the subtance in question and subsequently shaking the liquid vigorously. They can then be made into tablets and pills. Practitioners believe that the more a subtance is diluted in this way, the greater its power to treat symptoms.
However, in a new study, a working committee of medical experts at Australia’s National Health and Medical Research Council (NHMRC) has claimed that homeopathic medicines are only as effective as placebos at treating illness. Their research, involving the analysis of numerous reports from homeopathy interest groups and the public, concluded that there is no reliable evidence that homeopathy works.
Moreover, researchers uncovered no fewer than 68 ailments that homeopathic remedies had failed to treat, including asthma, sleep disturbances, cold and flu, and arthritis.
As a result of the findings, the NHMRC is urging health workers to inform their patients to be wary of anecdotal evidence that appears to support the effectiveness of homeopathic medicine. “It  isn’t possible to tell whether a health treatment is effective or not simply by considering the experience of one individual or the beliefs of a health practitioner,” says the report. Experts believe that most illnesses said to have been cured by homeopathy would be cured by the body on its own without taking the medicine. Apparently, many illnesses are short-lived by their very nature which often leads to people believing that it is the homeopathy that cures them.
A more serious matter is highlighted by Professor John Dwyer of the University of New South Wales. As an immunologist, he is concerned about homeopathic vaccinations on offer for diseases such as HIV, tuberculosis, and malaria, none of which he considers effective. According to Professor John Dwyer, the concept that homeopathic vaccinations are just as good as traditional vaccinations in delusion, and those who believe it are failing to protect themselves and their children.

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:
Alaska is disappearing slowly, but surely. It is estimated that since the 19505, as much as fifteen percent of Alaska's land area has disappeared. How can a whole state be disappearing? The problem is that Alaska’s glaciers are melting. The state has more than 100,000 glaciers. These glaciers account for about 75,000 square kilometers, or five percent, of the state’s area. That is an area of land larger than Ireland!
According to a recent report by the US Geological Survey, ninety-nine percent of Alaska's glaciers are either retreating or diminishing. This diminishing seems mainly due to the increase in global temperatures. Since the 19605, the average year-round temperature has increased by almost 3°C. Additionally, the average winter temperature has increased by over 6°C. Presently, an estimated 100 cubic kilometers of ice is disappearing from Alaskan glaciers every year. It may be even more in the near future, as some scientists predict that the average world temperature could go up 4 to 7°C by the year 2100.
Another problem facing Alaska is its thawing permafrost. Much of the land in Alaska used to be permanently frozen or frozen for most of the year. Now, the thawing permafrost is causing a number of problems for people living in Alaska. Roads and utility poles are collapsing as the ground around and under them warms and soften. Also, the hard permafrost that originally prevented beaches from eroding during violent storms is now melting. People who live along Alaska's coasts are being forced to relocate. For villages on small low islands, one terrible storm could wipe out the entire community.
The melting permafrost and increasing temperatures are both affecting the forests of Alaska. As the permafrost under the forests melts, insects that normally do not turn up until the warmer seasons are appearing sooner. The spruce-bark beetle, for example, is increasing in numbers as a result of warmer winter temperatures. It usually takes about two years for these beetles to grow and reproduce in. very cold weather. However, due to the increase in temperatures, spruce-bark beetles are reproducing faster and damaging as many trees in one year as they previously damaged in two. If something cannot be done to change things, Alaska's forests will not survive the turn of the century.
Some scientists believe that human activity is linked to a global increase in weather temperature.
Whatever the cause of rising temperatures may be, the fact remains that temperatures are warming, affecting Alaska for the worse. Horribly, this could be a preview of what will happen to the rest of the world in the next century.

According to the passage, the following are the problems caused by the melting permafrost, EXCEPT     .

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 word robot first appeared in a 1921 stage play by Czech writer Karel Capek. In the play, a man makes a machine that can think, which he calls a robot and which ends up killing its owner. In the 1940s, the American science fiction writer Isaac Asimov wrote a series of stories about robots and invented the term robotics, the science of robots. Meanwhile, in the real world, the first robots were developed by an engineer, Joseph F. Engelberger, and an inventor, George C. Devol. Together they started Unimation, a manufacturing company that produces the first real robot in 1961, called the Unimate. Robots of this type were installed at a General Motors automobile plant and proved to be a success. They worked reliably and saved money for General Motors, so other companies were soon acquiring robots as well.
These industrial robots were nothing like the terrifying creatures that can often be seen in science fiction films. In fact, these robots looked and behaved nothing like humans. They were simply pieces of computer-controlled machinery, with metal “arms” or “hands”. Since they were made of metal, they could perform certain jobs that were difficult or dangerous for humans, particularly jobs that involve high heat. And since robots were tireless and never got hungry, sleepy, or distracted, they were useful for tasks that would be tiring or boring for humans. Industrial robots have been improved over the years, and today they are used in many factories around the world. Though the use of robots has meant the loss of some jobs, at the same time other jobs have been created in the design, development, and production of the robots.

      Anthropogenic global warming is a theory explaining today's long-term increase in the average temperature of Earth's atmosphere as an effect of human industry and agriculture.
      Since the latter half of the 20th century, growing banks of data and improved climate models have convinced most climate scientists that rising trends in greenhouse gas emissions are directly responsible for a rising trend in atmospheric temperature. The source of these emissions vary, consisting of a mix of gases that include methane and carbon dioxide. While some sources - such as volcanoes - are natural, their overall emissions compared with those produced by human industries, transport, and livestock have been regarded as insignificant over recent centuries.
       Greenhouse gases are made of molecules that absorb electromagnetic radiation, such as  the light reflecting from the planet's surface, and re-emit it as heat. These gases include methane, carbon dioxide, water, and nitrous oxide. Despite making up only a small percentage of the atmosphere's mix of gases they are very important. If we had no naturally occurring greenhouse gases in the atmosphere at all, the average global temperature on Earth would be a much lower -18 degrees instead of the roughly 15 degrees Celsius we have enjoyed most of human history.
        Carbon dioxide levels have steadily risen over the past two centuries, thanks largely to the burning of fossil fuels for electricity general, transportation, and smelting. Current levels are approximately 415 parts per million (ppm), up from pre-industrial levels of around 280 ppm. Models vary in their predictions of further temperature increases, and depend heavily on future trends in greenhouse gas emissions. Conservative estimates by the Intergovernmental Panel on Climate Change predict an even chance of 4 degrees Celsius rise by the end of the century if current emissions trends continue.

According to paragraph 4, what are the CO2-producing fossil fuels utilized for?

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:
Since the world became industrialized, the number of animal species that have either become extinct or near extinction has increased. Bengal tigers, for instance, which once roamed the jungles in vast numbers, now number only about 2,300. By the year 2025, it is estimated that they will become extinct.
What is alarming about the case of the Bengal tiger is that this extinction will have been caused almost entirely by poachers who, according to some sources, are not always interested in material gain but in personal gratification. This is an example of the callousness that is contributing to the problem of extinction. Animals such as the Bengal tiger, as well as other endangered species, are valuable parts of the world/s ecosystem. International laws protecting animals must be enacted to ensure their survival-and the survival of our planet.
Countries around the world have begun to deal with the problem in various ways. Some countries, in an effort to circumvent the problem, have allocated large amounts of land to animal reserves. They then charge admission prices to help defray the costs of maintaining the parks, and they often must also depend on world organizations for support. This money enables them to invest in equipment and patrols o protect the animals. Another response to the increase in animal extinction is an international boycott of products made from endangered species. This has had some effect, but by itself will not prevent animals from being hunted and killed.a

The day after Thanksgiving is the start of the holiday shopping season. Thanksgiving is always on a Thursday, so the day after is a Friday. This day has come to be known as Black Friday. It has been the busiest shopping day of the year since 2005.
Most stores offer great deals on Black Friday. They open their doors in the wee hours of the morning. They try to attract shoppers with big discounts. Some items like TVs are much cheaper than usual. Stores may even lose money on these items. They hope that shoppers will buy gifts for other people while they are in the store.Black Friday is a great time to get good deals. The problem is that there are not enough low-priced items to go around. Each store may only have a few. These items are in high demand. People stand in long lines to get such great deals. They may line up hours before a store opens. They may be hoping to get a low price on a TV or laptop, but not everyone who wants one will get one. Some people leave disappointed. The situation can be tense. Some Black Friday events have been Violent. Large, eager crowds have trampled workers. Fights have broken out or people have been cutting in line. People have shot one another over parking spots. But most Black Friday events are safe and fun. Still, if you plan on going, expect large crowds and a bit of shoving.

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:
Telecommuting-substituting the computer for the trip to the job-has been hailed as a solution to all kinds of problems related to office work. For workers, it promises freedom from the office, less time wasted in traffic, and help with child-care conflicts. For management, telecommuting helps keep high performers on board, minimizes tardiness and absenteeism by eliminating commutes, allows periods of solitude for high-concentration tasks, and provides scheduling flexibility. In some areas, such as Southern California and Seattle, Washington, local governments are encouraging companies to start telecommuting programs in order to reduce rush-hour congestion and improve air quality, but these benefits do not come easily. Making a telecommuting program work requires careful planning and an understanding of the differences between telecommuting realities and popular images.
Many workers are seduced by rosy illusions of life as a telecommuter. A computer programmer from New York City moves to the tranquil Adirondack Mountains and stays in contact with her office via computer. A manager comes into his Office three days a week and works at home the other two. An accountant stays home to care for child; she hooks up her telephone modem connections and does office work between calls to the doctor.
These are powerful images, but they are a limited reflection of reality. Telecommuting workers soon learn that it is almost impossible to concentrate on work and care for a young child at the same time. Before a certain age, young children cannot recognize, much less respect, the necessary boundaries between work and family. Additional child support is necessary if the parent is to get any work done.
Management, too, must separate the myth from the reality. Although the media has paid a great deal of attention to telecommuting, in most cases it is the employee’s situation, not the availability of technology, that precipitates a telecommuting arrangement.
That is partly why, despite the widespread press coverage, the number of companies with work-at-home programs or policy guidelines remains small.

Which of the following is NOT mentioned as a problem for employers that is potentially solved by telecommuting?

The world needs to do more to prepare for the impact of a rapidly ageing population, the UN has warned - particularly in developing countries. Within 10 years the number of people aged over 60 will pass one billion, a report by the UN Population Fund said. The demographic shift will present huge challenges to countries’ welfare, pension and healthcare systems. The UN agency also said more had to be done to tackle "abuse, neglect and violence against older persons".
The number of older people worldwide is growing faster than any other age group. The report, Ageing in the let Century: A Celebration and a Challenge, estimates that one in nine people around the world are older than 60. The elderly population is expected to swell by 200 million in the next decade to surpass one billion, and reach two billion by 2050. This rising proportion of older people is a consequence of success - improved nutrition, sanitation, healthcare, education and economic well-being are contributing factors, the report says.
But the UN and a charity that also contributed to the report, Help Age International, say the ageing population is being widely mismanaged. "In many developing countries with large populations of young people, the challenge is that governments have not put policies and practices in place to support their current older populations or made enough preparations for 2050," the agencies said in a joint statement.

Orbis is an organisation which helps blind people of everywhere. It has built an eye hospital inside an aeroplane and flown it all over the world with an international medico team. Samantha Graham, a fourteen-year-old schoolgirl from England, went with the plane to Mongolia. Samantha tells the story, of the Eukhtuul, a young Mongolian girl.
'Last year, when Eukhtuul was walking home from school, she was attacked by boys with sticks and her eyes were badly damaged. Dr. Duffey, an Orbis doctor, said that without an operation she would never see again, I thought about all the things I do that she couldn't, things like reading schoolbooks, watching television, seeing friends, and I realised how lucky I am.'
'The Orbis team agreed to operate on Eukhtuul and I was allowed to watch, together with some Mongolian medical students. I prayed the operation would be successful. The next day I waited nervously with Eukhtuul while Dr. Duffey removed her bandages. "In six  months your sight will be back to normal," he said. Eukhtuul smiled, her mother cried, and I had to wipe away some tears, too!'
Now Eukhtuul wants to study hard to become a doctor. Her whole future has changed thanks to a simple operation. We should all think more about how much our sight means to us.’

What is the result of Eukhtuul's operation?

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:
Almost all living things ultimately get their energy from the sun. In a process called photosynthesis, plants, algae, and some other organisms capture the sun's energy and use it to make simple sugars such as glucose. Most other organisms use these organic molecules as a source of energy. Organic materials contain a tremendous amount of energy. As food, they fuel our bodies and those of most other creatures. In such forms as oil, gas, and coal, they heat our homes, run our factories and power our cars.
Photosynthesis begins when solar energy is absorbed by chemicals called photosynthetic pigments that are contained within an organism. The most common photosynthetic pigment is chlorophyll. The bright green color characteristic of plants is caused by it. Most algae have additional pigments that may mask the green chlorophyll. Because of these pigments, algae may be not only green but brown, red, blue or even black.
In a series of enzyme-controlled reactions, the solar energy captured by chlorophyll and other pigments is used to make simple sugars, with carbon dioxide and water as the raw materials. Carbon dioxide is one of very few carbon- containing molecules not considered to be organic compounds. Photosynthesis then converts carbon from an inorganic to an organic form. This is called carbon fixation. In this process, the solar energy that was absorbed by chlorophyll is stored as chemical energy in the form of simple sugars like glucose. The glucose is then used to make other organic compounds. In addition, photosynthesis produces oxygen gas. All the oxygen gas on earth, both in the atmosphere we breathe and in the ocean, was produced by photosynthetic organisms. Photosynthesis constantly replenishes the earth's oxygen supply.
Organisms that are capable of photosynthesis can obtain all the energy they need from sunlight and do not need to eat. They are called autotrophs. Plants are the most familiar autotrophs on land. In the ocean, algae and bacteria are the most important autotrophs. Many organisms cannot produce their own food and must obtain energy by eating organic matter. These are called heterotrophs.

Tides are the periodic rise and fall of the Earth’s waters that are caused by the Moon’s and Sun’s forces of gravity acting on the Earth .It is important to distinguish natural tidal phenomena from huge tsunamis , with the latter being caused by earthquakes and undersea volcanic eruptions.
The Moon is a main factor controlling ordinary tides. At the location on the Earth closest to the Moon, it exerts a powerful gravitational pull on the water. The resulting rise in the water produces higher tides. The water on the side of the Earth farthest away from the Moon also gets pulled by this lunar gravity, but not as strongly. The Earth itself has its own gravitational force that is constantly pulling waters downward, which is why the oceans do not simply bulge out toward the Moon. Ordinary tides usually feature high and low waters alternating in relation to the Earth’s rotation. Most shores around the world have high waters and two low waters for each day, which last about 24 hours and 50 minutes. The difference in height between the high water and low water is called the range of tide, and it can be quite dramatic in narrower bays
.Canada’s bays of Fundy , for example , commonly experiences the world’s most extreme tidal ranges , with daily differences of the 16 meters.
Two other types of tides are influenced by the Sun, which is much farther away from the Earth and exerts less than half of the Moon’s gravitational force. When the Sun, the Moon and the Earth are directly in line, the solar and lunar gravitational forces add up to produce higher spring tides. The range of spring tides is intensified, with higher water marks and lower low water marks. However, when the Moon is in the first or third quarter, it is at a 90–degree angle with the Sun in relation to the Earth .The opposing solar and lunar forces partially cancel each other out, and the result is a lower tide. This is called a neap tide, which comes twice a month and has lower high water marks and higher low water marks. The range of neap tides is minimum.
Some tides do not occur over water at all. The solid body of the Earth has slight elasticity, so lunar and solar gravity cause it to stretch very subtly. These changes in the Earth’s shape, although imperceptible to humans, are known as Earth tides.
Another tidal phenomenon, atmospheric tides, is caused by the Sun’s heating of the Earth’s atmosphere. Like ordinary tides, they usually occur over 12–hour periods.

It is hard to get any agreement on the precise meaning of the term "social class". In everyday life, people tend to have a different approach to those they consider their equals from which they assume with people they consider higher or lower than themselves in social scale. The criteria we use to 'place' a new acquaintance, however, are a complex mixture of factors. Dress, way of speaking, area of residence in a given city or province, education and manners all play a part.
In ancient civilizations, the Sumerian, for example, which flourished in the lower Euphrates valley from 2000 to 5000 B.C. social differences were based on birth, status or rank, rather than on wealth. Four main classes were recognized. These were the rulers, the priestly administrators, the freemen (such as craftsmen, merchants or farmers) and the slaves.
In Greece, after the sixth-century B.C., there was a growing conflict between the peasants and the aristocrats, and a gradual decrease in the power of the aristocracy when a kind of ‘middle class’ of traders and skilled workers grew up. The population of Athens, for example, was
divided into three main classes which were politically and legally distinct. About one-third of the total population was slaves, who did not count politically at all, a fact often forgotten by those who praise Athens as the nursery of democracy. The next main group consisted of resident foreigners, the, ‘metics’ who were freemen, though they too were allowed no share in political life. The third group was the powerful body of ‘citizens”, who were themselves divided into sub- classes.
In the later Middle Ages, however, the development of a money economy and the growth of cities and trade led to the rise of another class, the ‘burghers’ or city merchants and mayors. These were the predecessors of the modern middle classes. Gradually high office and occupation assumed importance in determining social position, as it became more and more possible for a person born to one station in life to move to another. This change affected the towns more than the country areas, where remnants of feudalism lasted much longer.

There are many mistakes that people make when writing their resume (CV) or completing a job application. Here are some of the most common and most serious.
The biggest problem is perhaps listing the duties for which you were responsible in a past position: all this tells your potential employers is what you were supposed to do. They do not necessarily know the specific skills you used in executing them, nor do they know what results you achieved - both of which are essential. In short, they won’t know if you were the best, the worst or just average in your position.
The more concrete information you can include, the better. As far as possible, provide measurements of what you accomplished. If any innovations you introduced saved the organization money, how much did they save? If you found a way of increasing productivity, by what percentage did you increase it?
Writing what you are trying to achieve in life - your objective - is a waste of space. It tells the employer what you are interested in. Do you really think that employers care what you want? No, they are interested in what they want! Instead, use that space for a career summary. A good one is brief - three to four sentences long. A good one will make the person reviewing your application want to read further.
Many resumes list ‘hard' job-specific skills, almost to the exclusion of transferable, or ‘soft’, skills. However, your ability to negotiate effectively, for example, can be just as important as your technical skills.
All information you give should be relevant, so carefully consider the job for which you are applying. If you are applying for a job that is somewhat different than your current job, it is up to you to draw a connection for the resume reviewer, so that they will understand how your skills will fit in their organization. The person who reviews your paperwork will not be a mind reader.
If you are modest about the skills you can offer, or the results you have achieved, a resume reader may take what you write literally, and be left with a low opinion of your ability: you need to say exactly how good you are. On the other hand, of course, never stretch the truth or lie.

Why did the author mention that applicants should write a good brief career summary?

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. 
There are many different metaphors used to describe culture. My favorite one is the iceberg. I think, it demonstrates so vividly what can happen to us if we believe only in the visible and ignore or underestimate the invisible part. The hidden part of our culture is that part which we know instinctively because we absorbed it from childhood on. It's handed down to us from generation to generation. We could also say, it's the "thinking" and "feeling" part of culture: habits, assumptions, attitudes, desires, values, tastes, etc.
Now, if we are in a new culture, our customary evaluations and interpretations are likely not to be on target because we see everything through our own cultural glasses. Imagine yourself in a new city trying to get around with a map from your own hometown. It wouldn't take long for you to get lost and completely frustrated! When we experience an encounter in the new culture that puzzles us, the most common reaction is to judge it through our own cultural glasses. 
I want to propose an alternate approach to our initial gut reaction. Instead of immediately and instinctively judging a situation through our own glasses, we might first just pause and notice what is happening and then realize that this is a cultural learning situation. Remember the iceberg metaphor! The new culture becomes your mirror that shows you a hidden part of your own culture. What an opportunity for personal growth and new insight! You can compare two different approaches, that of the new culture and of your own culture. This gives you a choice. Now you can decide what fits best for you or even take the best from both sides. 

The word “it” in paragraph 2 refers to _______.

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:
Nature has always provided a stimulus for inventive minds. Early flying machines clearly were an attempt to emulate the freedom of birds. Architects and engineers have often consciously modeled buildings on forms found in nature. A more recent example of the inspiration given by nature is the invention of Velcro®. The inventor of this now common fastening device noticed that small burrs attached to his dog's coat grasped the hairs by means of tiny hooks. This led him to invent a synthetic fabric whose surfaces mimic the clasping properties of this natural seedpod.
Animals and plants have evolved solutions to the kinds of problems that often interest engineers  and designers. Much current research in material science is concerned with actively examining the natural world, especially at the molecular level, for inspiration to develop materials with novel properties. This relatively new field of study is sometimes known as biomimetics, since it consciously attempts to mimic nature.
Researchers have investigated several interesting areas. For example, they have studied how the molecular structure of antler bone contributes to its amazing toughness, how the skin structure of a worm contributes to its ability to crawl, how the sea cucumber softens its skeleton and changes shape so that it can squeeze through tiny gaps in rocks, or what gives wood its high resistance to impact. These investigations have led to several breakthroughs in the development of composite materials with remarkable properties.
Predictions for future inventions that may be developed from these lines of research include so- called smart structures that design and repair themselves in a similar way to a variety of processes in the natural world. For example, engineers have envisaged bridges that would detect areas heavily stressed by vehicle movement or wind. The bridge structure would then automatically add or move material to the weak areas until the stress is reduced. The same principle might be used to repair damaged buildings. Other new materials that have been imagined are substances that would copy photosynthesis in green plants in order to create new energy sources. The potential impact of biomimetic research is so great that the twenty-first century may come to be known as the "Age of Materials."
