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

What is 'extreme' weather? Why are people talking about it these days? 'Extreme' weather is an unusual weather event such as rainfall, a drought or a heat wave in the wrong place or at the wrong time. In theory, they are very rare. But these days, our TV screens are constantly showing such  extreme weather events. Take just three news stories from 2010: 28 centimetres of rain fell on Riode Janeiro in 24 hours, Nashville, USA, had 33 centimetres of rain in two days and there was record  rainfall in Pakistan.

The effects of this kind of rainfall are dramatic and lethal. In Rio de Janeiro, landslides followed,  burying hundreds of people. In Pakistan, the floods affected 20 million people. Meanwhile, other parts of the world suffer devastating droughts. Australia, Russia and East Africa have been hit in the last ten years. And then there are unexpected heat waves, such as in 2003 in Europe. That summer, 35,000 deaths were said to be heat-related.

So, what is happening to our weather? Are these extreme events part of a natural cycle? Or are they caused by human activity and its effects on the Earth's climate? Peter Miller says it's probably a mixture of both of these things. On the one hand, the most important influences on weather events are natural cycles in the climate. Two of the most famous weather cycles, El Niño and La Niña, originate in the Pacific Ocean. The heat from the warm ocean rises high into the atmosphere and affects weather all around the world. On the other hand, the temperature of the Earth's oceans is slowly but steadily going up. And this is a result of human activity. We are producing greenhouse gases that trap heat in the Earth's atmosphere. This heat warms up the atmosphere, land and oceans.   Warmer oceans produce more water vapour - think of heating a pan of water in your kitchen. Turn up the heat, it produces steam more quickly. Satellite data tells US that the water vapour in the atmosphere has gone up by four percent in 25 years. This warm, wet air turns into the rain, storms, hurricanes and typhoons that we are increasingly experiencing. Climate scientist, Michael Oppenheimer, says that we need to face the reality of climate change. And we also need to act now to save lives and money in the future.

Mark the letter A, B, C, or D on your answer sheet to indicate the undelined part that needs correction in each of the following questions:
Under certain circumstances, the human body must cope with gases at greater-than-normal atmospheric pressure. For example, gas pressures increase rapidly during a drive made with scuba gear because the breathing equipment allows divers to stay underwater longer and dive deeper. The pressure exerted on the human body increases by 1 atmosphere for every 10 meters of depth in seawater, so that at 39 meters in seawater a diver is exposed to pressure of about 4 atmospheres. The pressure of the gases being breathed must equal the external pressure applied to the body,

otherwise breathing is very difficult. Therefore all of the gases in the air breathed by a scuba diver at 40 meter are present at five times their usual pressure. Nitrogen, which composes 80 percent of the air we breathe, usually causes a balmy feeling of well-being at this pressure. At a depth of 5 atmospheres, nitrogen causes symptoms resembling alcohol intoxication, known as nitrogen narcosis. Nitrogen narcosis apparently results from a direct effect on the brain of the large amounts of nitrogen dissolved in the blood. Deep dives are less dangerous if helium is substituted for nitrogen, because under these pressures helium does not exert a similar narcotic effect.
As a scuba diver descends, the pressure of nitrogen on the lungs increases. Nitrogen then diffuses from the lungs to the blood, and from the blood to body tissues. Nitrogen then diffuses from the lungs to the blood, and from the blood to body tissues The reverse occurs when the diver surfaces, the nitrogen pressure in the lungs falls and the nitrogen diffuses from the tissues into the blood, and from the blood into the lungs. If the return to the surface is too rapid, nitrogen in the tissues and blood cannot diffuse out rapidly enough and nitrogen bubbles are formed. They can cause severe pains, particularly around the joints.
Another complication may result if the breath is held during ascent. During ascent from a depth of 10 meters, the volume of air in the lungs will double because the air pressure at the surface is only half of what it was at 10 meters. This change in volume may cause the lungs to distend and even rupture. This condition is called air embolism.
To avoid this event, a diver must ascend slowly, never at a rate exceeding the rise of the exhaled air bubbles, and must exhale during ascent.

The word “rupture” in bold in paragraph 3 is closest in meaning to     .

It was not until 1920 when women finally got the right to vote. This was 50 years after the male ex-slaves of the United States were gaining the right to vote. Though women had already right to vote, the stereotypes made women be restricted in their actions. Would you believe that women who were doing the same job as men were getting paid only the 60% of what man wear to paint? In fact, they were getting paid differently for doing exactly the same work. In the 1930s there was not a huge choice of workplace for women. They could still work as secretaries, nurses, teachers and social workers. These kinds of professions were considered typically female professions and were paid much less than other professions. That kind of restrictions themed unbearable for some women. They rejected to go on with this rules anymore. They changed their hair color, style appearance and started to fight against the existing stereotypes. Those women were named in history as “flappers”. The first time in history they started wearing short skirts which were something shocking to the society. They also started driving cars, drinking alcohol, which raised a huge boom. Those kinds of things were considered “Non-feminine”. Actions of flappers were accepted as radical, though they had their influence on the society finally. The heavy restrictions started disappearing every year and today we have what we have. For a very long time, women were considered inferior to men. However, the role of a woman in society has significantly changed during recent decades. Today the importance of women in the society is beyond any suspicion. In today’s world, women with their ambitions, intelligence and strength have proved that the word “inferior” has nothing in common with their gender.

Read the following passage and choose the best answer (A, B, C, D):
Plastic bags are used by everybody. From a vegetable vendor to a designer store, everyone seems to use them. Even though they are one of the modern conveniences that we seem to be unable to do without, they are responsible for causing pollution, killing wildlife, and using up the precious resources of the Earth. But, most of us are blissfully unaware of the repercussions that are occurring and will take place in the future because of the plastic bags. Every once in a while, the government passes out an order banning store owners from providing plastic bags to customers for carrying their purchases, with little lasting effect. Plastic bags are very popular with both retailers as well as consumers because they are cheap, strong, lightweight, functional, as well as a hygienic means of carrying food as well as other goods. About a hundred billion plastic bags are used every year in the U.S. alone. And then, when one considers the huge economies and populations of India, China, Europe, and other parts of the world, the numbers can be staggering. The problem is further exacerbated by the developed countries shipping off their plastic waste to developing countries like India. Once they are used, most bags go into landfills. Each year, more and more bags are ending up littering the environment. Once they become litter, plastic bags find their way into our waterways, parks, beaches, and streets. And, if they are burned, they infuse the air with toxic fumes. About 100,000 animals, such as dolphins, turtles, whales, penguins are killed every year due to these bags. Many animals ingest plastic bags, mistaking them for food, and therefore, die. And worse, the ingested plastic bag remains intact even after the death and decomposition of the animal. Thus, it lies around in the landscape where another victim may ingest it. One of the worst environmental effects is that they are non-biodegradable. The decomposition takes about 400 years. No one will live so long to witness the decomposition of plastic! Thus, save the environment for the future generations as well as animals. Petroleum products are diminishing and getting more expensive by the day, since we have used this non-renewable resource increasingly. And to make plastic, about 60-100 million barrels of oil are needed every year around the world. Surely, this precious resource should not be wasted on producing plastic bags, should it? Petroleum is vital for our modern way of life. It is necessary for our energy requirements - for our factories, transportation, heating, lighting, and so on. Without viable alternative sources of energy yet on the horizon, if the supply of petroleum were to be turned off, it would lead to practically the entire world grinding to a halt. So, what can be done? A tote bag can make a good substitute for carrying groceries and the shopping. You can keep the bag with the cashier, and then put your purchases into it instead of the usual plastic bag. Recycling the bags you already have is another good idea. These can come into use for various purposes, like holding your garbage, instead of purchasing new ones. While governments may be working out ways to lessen the impact of plastic bags on the environment; however, each of us should shoulder some of the responsibility for this problem, which ultimately harms us. Plastics are not only nonbiodegradable, but are one of the major pollutants of the sea. For a clean and green environment, try to use alternatives to plastic whenever and wherever possible. Cut down your use of plastic, and do your bit to save our planet  
3. According to the second paragraph, what is NOT true about the reality of plastic bags?

Money habits matter a lot in a relationship, even if you’re not married or living together, concludes Melissa A Curran, an associate professor at the University of Arizona, in a new study published in the Journal of Family and Economic Issues. That’s why she recommends being picky when it comes to dating. “Young adults should choose their romantic partner wisely,” Curran tells CNBC Make It. She and her colleagues assessed over 500 young twenty-somethings in committed relationships and had them rate their health and overall life satisfaction. She asked them questions related to their partners’ financial responsibility, such as, Do they spend within a budget? And, Do they usually pay off their credit cards in full? The researchers found that the more responsible the participants perceived their partners to be with money, the higher their own sense of well-being and the happier they were with their relationships. The opposite was also true. Participants who thought their partners were bad with money had a lower sense of well-being and felt less committed to the relationship. “This finding makes sense developmentally as the young adults are transitioning to adulthood,” says Curran. “It would make sense for them to draw upon romantic partners in terms of financial socialization agents.” By socialization agents, she means people who can teach and influence the participants on matters related to money. The idea is that the financial habits of whoever you’re dating can rub off on you. If your partner is bad with money, you might become bad with money too, which in turn affects your life overall, since the researchers also confirmed that your own financial habits definitely affect your well-being. For many young adults, parents are the most influential socialization agents. So, in this study, Curran also asked the participants about what their parents expected of them when it came to their finances. Did their parents, for example, expect them to track their spending? The researchers found that high expectations from an involved parent led the participants to perform better on a financial literacy test. But, unlike romantic partners, they did not seem to influence well-being. If you’re bothered by your significant other’s over-spending or general irresponsibility with money, Curran and her colleagues recommends talking things through. “Having discussions about finances and making financial decisions together helps couples
become closer and more satisfied with their relationships.”

Read the following passage and choose the best answer (A, B, C, D):
Go is a game that has been around for 3000 years. It is widely accepted as the most challenging strategy game that exists. It takes years of playing for several hours every day to master the game. In other words, even though it has simple rules, it is not a simple game to excel at. Surprise! Deep Mind managed to create a machine that could master the game, without being programmed with explicit rules and without being taught by a professional Go player. AlphaGo mainly played against itself and learned from this self-play. At its core, it learned like a human learns, by looking at the board, evaluating the options, making moves, and learning from mistakes - it just did it a lot faster than any human can. This is extremely exciting because, at its core, what it means is that computer scientists have had all the tools they needed to do this for years. Neural networks have been known about and discussed since the middle of the last century. All it really took was simply getting creative with them, applying them in new ways. AlphaGo beating the world’s best Go player proves that AI has the potential to do anything. It can learn anything and understand anything, and from that learning and understanding it can accomplish what humans can accomplish in a much shorter period of time. You’re probably wondering what this all means. We’re much closer to the dream of an AI best friend than most of us would have dared to imagine a few years ago. AlphaGo can learn the most complex, intuition and creativity based logic game known to man and it didn’t do so through a finite database or search trees alone. It learned from practice and experience, just like we do, and the ability to create amazing new solutions to ancient puzzles suggests a realm of digital creativity never before fathomed. AlphaGo is not like other game playing AIs that have come before it. It is the future of intelligent and intuitive machines, one that we plan to turn toward more than just board games. From practical applications to that friend you’ve been hoping for, AlphaGo is sure to be the first of a new generation of self-learning intuitive AIs that go above and beyond the limited calculating capacities of its older siblings and contemporaries. The AI winter is over.
4. According to paragraph 2, what is the emphasised difference between AlphaGo and human?

Read the following passage and choose the best answer (A, B, C, D):
The temperature of the earth is rising at nearly twice the rate it was 50 years ago. This rapid rate and pattern of warming, scientists have concluded, cannot be explained by natural cycles alone. The only way to explain the pattern is to include the effect of greenhouse gases (GHGs) emitted by humans. To come to a conclusion on climate change, the United Nations formed a group of scientists called the Intergovernmental Panel on Climate Change, or IPCC. The IPCC meets every few years to review the latest scientific findings and write a report summarizing all that is known about global warming. Each report represents a consensus, or agreement, among hundreds of leading scientists. One of the first things the IPCC learned is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. Most come from the combustion of fossil fuels in cars, factories and electricity production. The gas responsible for the most warming is carbon dioxide, also called CO2. Other contributors include methane released from landfills and agriculture, especially from the digestive systems of grazing animals, nitrous oxide from fertilizers, gases used for refrigeration and industrial processes, and the loss of forests that would otherwise store CO2. Different greenhouse gases have very different heat-trapping abilities. Some of them can even trap more heat than CO2. A molecule of methane produces more than 20 times the warming of a molecule of CO2. Nitrous oxide is 300 times more powerful than CO2. Other gases, such as chlorofluorocarbons, or CFCs, which have been banned in much of the world because they also degrade the ozone layer, have heat-trapping potential thousands of times greater than CO2. But because their concentrations are much lower than CO2, none of these gases adds as much warmth to the atmosphere as CO2 does. In order to understand the effects of all the gases together, scientists tend to talk about all greenhouse gases in terms of the equivalent amount of CO2. Since 1990, yearly emissions have gone up by about 6 billion metric tons of “carbon dioxide equivalent” worldwide, more than a 20 percent increase.  
7. It can be inferred from paragraph 5 that CO2 _____

It’s often said that we team things at the wrong time. University students frequently do the minimum of work because they’re crazy about a good social life instead. Children often scream before their piano practice 5 because it’s so boring. They have to be given gold stars and medals to be persuaded to swim, or have to be bribed to take exams. But the story is different when you’re older.
Over the years, I’ve done my share of adult learning. At 30, I went to a college and did courses in History and English. It was an amazing experience. For starters, I was paying, so there was no reason to be late - I was the one frowning and drumming my fingers if the tutor was late, not the other way round. Indeed, if I could persuade him to linger for an extra five minutes, it was a bonus, not a nuisance. I wasn’t frightened to ask questions, and homework was a pleasure not a pain. When I passed an exam, I had a big meal, not for my parents or my teachers. The satisfaction I got was entirely personal.
Some people fear going back to school because they worry that their brains have got rusty. But the joy is that, although some parts have rusted up, your brain has learnt all kinds of other things since you were young. It has learnt to think independently and flexibly and is much better at relating one thing to another. What you lose in the rust department, you gain in the maturity department.
In some ways, age is a positive plus. For instance, when you’re older, you get less frustrated. Experience has told you that, if you’re calm and simply do something carefully again and again, eventually you’ll get the hang of it. The confidence you have in other areas - from being able to drive a car, perhaps - means that if you can’t, say, build a chair instantly, you don’t, like a child, want to destroy your first pathetic attempts. Maturity tells you that you will, with application, eventually get there.
I hated piano lessons at school, but I was good at music. And coming back to it, with a teacher who could explain why certain exercises were useful and with musical concepts that, at the age of ten. I could never grasp, was magical. Initially, I did feel a bit strange, thumping out a piece that I’d played for my school exams, with just as little comprehension of what the composer intended as I’d had all those years before. But soon, complex emotions that I never knew poured out from my fingers, and suddenly I could understand why practice makes perfect.

In the USA, the UK and many other countries, a lot of babies were born in the “baby boom” of the late 1940s and 1950s; after that the birth-rate fell. Baby boomers have now retired, or are approaching retirement, and this is causing headaches for many organizations: there are not enough people to succeed their top managers when they retire.
Does your organization have key staff who can’t easily be replaced? A CEO or financial director, perhaps, or a technical expert with knowledge that nobody else in the organization has. If your answer is “yes”, what will happen when they retire, or leave for another company? Will you wait until the last moment before looking for someone to replace them? Or is your organization thinking about likely future changes now, as it should be, and making plans, so that there is likely to be someone ready to replace the person leaving? If the answer is that you are planning ahead, your organization is carrying out succession planning.
Succession planning means looking inside the organization for “high-fliers” - current staff members with the potential to fill key positions - and planning the training, responsibilities and promotion they need, to make them ready when a senior vacancy occurs - which may not be for several years. The company benefits by being able to make an internal promotion when a key person leaves, and in the meantime it benefits by developing the skills of its high-fliers and encouraging them to stay. And the high-fliers benefit, because they achieve their full potential, a career is planned for them within the organization, and they can look forward to a senior post in time.
The training program planned for the high-fliers will help them to develop the leadership skills they need for more senior roles, skills such as planning long-term strategies. A career path is also planned, so that each high-flier moves into a number of different positions over a few years, to gain the experience and know ledge they need.
Sometimes a staff member is chosen as a potential successor to a particular senior manager, but a better method is for organizations to select a number of high-fliers, and prepare them for a range of senior roles. An organization can’t be certain when a particular senior manager will leave. Having a group of people being prepared fee top positions makes it easier to replace someone who leaves unexpectedly, and also means that there are other people available if a high-flier leaves the company.

All of the following are mentioned as benefits of succession planning EXCEPT     .

Read the following passage and choose the best answer (A, B, C, D):
Chichen-Itza is protected by the 1972 Federal Law on Monuments and Archaeological, Artistic and Historic Zones and was declared an archaeological monument by a presidential decree in 1986. The site remains open to the public 365 days of the year, and received a minimum of 3.500 tourists per day, a number which can reach 8.000 daily visitors in the high season. This means that the site needs constant maintenance and attention in order to avoid deterioration of its pre-hispanic fabric. Yucatan is the only state in Mexico where two institutions are involved in the management of archaeological sites: the National Institute of Anthropology and History (INAH), which is in charge of the care and conservation of the archaeological site, and the other is Board of Units of Cultural and Tourism Services of the State of Yucatan. Medium and long-term activities at Chichen-Itza, including investigation, conservation, thematic interpretation, administration and operation of the site, are addressed in the “Management Plan of the Pre-hispanic City of Chichen-Itza”. The purpose of the Plan is to articulate and coordinate the activities at the site, especially those geared towards the mise en valeur of the property and the generation of participation of the different sectors involved in the management, including the general public. No emergency plan exists for the site and there is no long term monitoring of the state of conservation, due to lack of personnel. This puts the site at risk from natural and anthropogenic disasters, as well as from longer term degradation. Threats like fire and lime stone erosion have been highlighted. Sustainable implementation of the defined planning tools and the allocation of resources to conservation and management are necessary means to ensure the conservation of the Outstanding Universal Value of the property in the long term.

Music can bring us to tears or to our feet, drive us into battle or lull us to sleep. Music is indeed remarkable in its power over all humankind, and perhaps for that very reason, no human culture on earth has ever lived without it. From discoveries made in France and Slovenia, even Neanderthal man, as long as 53,000 years ago, had developed surprisingly sophisticated, sweet- sounding flutes carved from animal bones. It is perhaps then, no accident that music should strike such a chord with the limbic system – an ancient part of our brain, evolutionarily speaking, and one that we share with much of the animal kingdom. Some researchers even propose that music came into this world long before the human race ever did. For example, the fact that whale and human music have so much in common even though our evolutionary paths have not intersected for nearly 60 million years suggests that music may predate humans. They assert that rather than being the inventors of music, we are latecomers to the musical scene.
Humpback whale composers employ many of the same tricks that human songwriters do. In addition to using similar rhythms, humpbacks keep musical phrases to a few seconds, creating themes out of several phrases before singing the next one. Whale songs in general are no longer than symphony movements, perhaps because they have a similar attention span. Even though they can sing over a range of seven octaves, the whales typically sing in key, spreading adjacent notes no farther apart than a scale. They mix percussive and pure tones in pretty much the same ratios as human composers – and follow their ABA form, in which a theme is presented, elaborated on and then revisited in a slightly modified form. Perhaps most amazing, humpback whale songs include repeating refrains that rhyme. It has been suggested that whales might use rhymes for exactly the same reasons that we do: as devices to help them remember. Whale songs can also be

rather catchy. When a few humpbacks from the Indian Ocean strayed into the Pacific, some of the whales they met there quickly changed their tunes – singing the new whales’ songs within three short years. Some scientists are even tempted to speculate that a universal music awaits discovery.

The underlined word “refrains” in paragraph 2 is closest in meaning to     .

Light-emitting diodes (LEDs) are now considered the future of lighting due to a lower energy requirement to run, a lower monthly price tag, and a longer life than traditional incandescent light bulbs. Nick Holonyak, an American scientist at General Electric, accidently invented the red LED light while trying to create a laser in the early 1960s. As with other inventors, the principle that some semiconductors glowed when an electric current was applied had been known since the early 1900s, but Holonyak was the first to patent it for use as a light fixture. Within a few years, yellow and green LEDs were added to the mix and used in several applications including indicator lights, calculator displays, and traffic lights, according to the DOE. The blue LED was created in the early 1990s by Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura, a group of Japanese and American scientists, and for which they won the 2014 Nobel Prize in Physics. The blue LED allowed scientists to create white LED light bulbs by coating the diodes with phosphor Today, lighting choices have expanded and people can choose different types of light bulbs, including compact fluorescent (CFL) bulbs work by heating a gas that produces ultraviolet light and LED bulbs. Several lighting companies are pushing the boundaries of what light bulbs can do, including Phillips and Stack. Phillips is one of several companies that have created wireless light bulbs that can be controlled via smartphone app. The Phillips Hue uses LED technology that can quickly be turned on or off or dimmed by a flick on a smart phone screen and can also be programmed. The higher-end Hue light bulbs can even be set to a large range of colors (only about sixteen million) and synced with music, movies, and video games. Stack, begun by engineers from Tesla and NASA, developed a smart light bulb using LED technology with a wide range of functions. It can automatically sense the ambient lighting and adjust as needed, it turns off and on via motion sensor when someone enters the room, can be used as a wake up alert, and even adjusts color throughout the day to fit with human’s natural circadian cycles and patterns of natural light. The light bulbs also have a built-in learning program that adapts to inputs given by residents over time. And all of these functions can be programmed or monitored from any smart phone or tablet. It is estimated that Stack smart light bulbs can use about sixty percent less energy than a typical LED light bulb and lasts between twenty and thirty thousand hours depending on the model . These light bulbs are compatible (or soon will be) with many of the options for turning an entire home into a smart home including usage with Amazon Alexa, Google Home, and Apple HomeKit.
