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:
Vietnam’s population is ageing quickly. In 2017, more than 10 per cent of the population will be 60 and older, and in 15-20 years the elderly will account for one third of the total population. This raises concerns about healthcare, welfare and pensions for the elderly at a time when Vietnam is focusing on economic integration and requires a large labor force. So far two solutions have been proposed: to loosen the two-child policy and to increase the retirement age to 58 for women and 62 for men. By ending the two-child policy the government expects to make up for the ageing population within the next 20
years. But its effect could be creating an uncontrollable boom in the Vietnamese population. When the government loosened the two-child policy in 2015 in a trial period, in the first 6 months of 2016 the third child birth rate increased remarkably by 7.5 per cent
Raising the retirement age has been proposed by the Ministry of Labor pending parliamentary evaluation in May 2017. While the policy is beneficial in utilizing the work experience of the elderly while creating savings in the pension budget, it also means fewer job prospects and promotion opportunities for younger generations. It is also not in the interest of all the elderly, especially the 70 per cent of Vietnam's labor force working in manual labor-intensive sectors such as agriculture, manufacturing and construction where working above the age of 50 can be dangerous and unproductive. Despite these drawbacks, raising the retirement age is still considered by policymakers as one of the key solutions to the ageing population problem in Vietnam. However, these are only temporary solutions.

There are a number of natural disasters that can strike across the globe. Two that are frequently linked to one another are earthquakes and tsunamis. Both of them can cause a great amount of devastation when they hit. However, tsunamis are the direct result of earthquakes and cannot happen without them.
The Earth has three main parts. They are the crust, the mantle, and the core. The crust is the outer layer of the Earth. It is not a single piece of land. Instead, it is comprised of a number of plates.
There are a few enormous plates and many smaller ones. These plates essentially rest upon the mantle, which is fluid. As a result, the plates are in constant – yet slow – motion. The plates may move away from or toward other plates. In some cases, they collide violently with the plates adjoining them. The movement of the plates causes tension in the rock. Over a long time, this tension may build up. When it is released, an earthquake happens.Tens of thousands of earthquakes happen every year. The vast majority are so small that only scientific instruments can perceive them. Others are powerful enough that people can feel them, yet they cause little harm or damage. More powerful earthquakes, however, can cause buildings, bridges, and other structures to collapse. They may additionally injure and skill thousands of people and might even cause the land to change it appearance.
Since most of the Earth’s surface is water, numerous earthquakes happen beneath the planet’s oceans. Underwater earthquakes cause the seafloor to move. This results in the displacement of water in the ocean. When this occurs, a tsunami may form. This is a wave that forms on the surface and moves in all directions from the place where the earthquake happened. A tsunami moves extremely quickly and can travel thousnads of kilometres. As it approaches land, the water near the coast gets sucked out to sea. This causes the tsunamis to increase in height.
Minutes later, the tsunami arrives. A large tsunami – one more than ten meters in height – can travel far inland. As it does that, it can flood the land, destroy human settlements, and kill large numbers of people

Ambient divers are, unlike divers who go underwater in submersible vehicles of pressure resistant suits, exposed to the pressure and temperature of the surrounding ambient water. Of all types of diving, the oldest and simplest is free diving. Free divers may use no equipment at all, but most use a face mask, foot fins, and a snorkel. Under the surface, free divers must hold their breath. Most free divers can only descend 30 to 40 feet, but some skilled divers can go as deep as 100 feet.
Scuba diving provides greater range than free diving. The word scuba stands for self-contained underwater breathing apparatus. Scuba divers wear metal tanks with compressed air or other breathing gases. When using open-circuit equipment, a scuba diver simply breathes air form the tank through a hose and releases the exhaled air into the water. A closed-circuit breathing device, also called a rebreather, filters out carbon dioxide and other harmful gases and automatically adds oxygen. This enables the diver to breathe the same air over and over. In surface-supplied diving, divers wear helmets and waterproof canvas suits. Today, sophiticated plastic helmets have replaced the heavy copper helmets used in the past.These divers get their air from a hose connected to compressors on a boat. Surface-supplied divers can go deeper than any other type of ambient diver.

What are the helmets that surface-supplied divers use today made from, according to the passage?

Grandparents are becoming the forgotten generation, with youngsters now too busy to listen to their stories from the olden days.
A study of 1,000 five to 18 year-olds reveals just 21 per cent will visit their older relatives to hear about how their lives were different in the  past; such as  where they worked, how it was living in the war, and how they met the love of their life. More than half of youths have no idea what job their grandparent did before retirement - admitting they'd never thought to ask. Sadly, one in 10 admitted they are simply not interested in their grandmother's or grandad's previous job or talents and interests, and a quarter only turn up to see  them for pocket money. But 23 per cent claim the reason they don't know  anything about their older relatives is  because they don't really get  the chance to talk properly.
Geoff Bates, spokesman for McCarthy 8/. Stone's Inspirational Generation campaign, said: We know this generation have lived full lives with heroic tales to tell and so much to offer, but how many  of us have actually thought to ask these questions of our older family members? We want to shout about the amazing feats retirees have achieved in their lifetime and put the spotlight on the wonderfully colorful lives of today's older people. We are calling on parents and children to talk to   their grandparents, to find out what they have done in their lives - and continue to do, and tell us all about it so we can give them the credit they deserve."
Researchers found that although 65 per cent of youngsters do see their grandparents every single week, 37 per cent claim this is only because their parents want them to. And while 39 per cent talk to their grandparents on the phone, Facebook or Skype at least once a week -  16  per cent once a day - conversation is rarely focused on what they are doing or have done in  the past.  Four in 10 kids have no idea what their grandparents proudest achievements are, while 30 per cent don't know if they have any special skills or talents. And 42 per cent don't spend any time talking about their grandparent's history -and are therefore clueless about what their grandmother or grandad was like when they were younger. Perhaps due to this lack of communication and respect, just six per cent of children say they look up to their grandparents as a role model and inspiration. However, grandchildren are agreed their grandparents are both loving and friendly, while 43 per cent think they're funny - with 23 per cent admitting they often have more fun with their elderly relatives than their parents.

Millions of people tune into the weather forecast each evening on televisions. Most of them imagine that the presenter does little more than arrive at the studio a few minutes before the broadcast, read the weather, and then go home.
In fact, this imagine is far from the truth. The two-minute bulletin which we all rely on when we need to know tomorrow’s weather is the result of a hard day’s work by the presenter, who is actually a highly-qualified meteorologist.
Every morning after arriving at the TV studios, the first task of the days is to collect the latest data from the national Meteorological Office. This office provides up-to-the- minute information about weather conditions throughout the day, both in Britain and around the world. The information is very detailed and includes predictions, satellite and radar pictures, as well as more technical data. After gathering all the relevant material from this office, the forecaster has to translate the scientific terminology and maps into images and word which viewers can easily understand.
The final broadcast is then carefully planned. It is prepared in the same way as other programmes. The presenter decides what to say and in what order to say it. Next, a “story board” is drawn up which lay out the script word for word. What make a weather forecast more complicated than other programmes are the maps and electronic images which are required. The computer has to be programmed so that the pictures appear in the correct order during the bulletin.
The time allocated for each broadcast can also alter. This is because the weather report is screened after the news, which can vary in length. The weather forecaster doesn’t always know how much time is available, which means that he/ she has to be thoroughly prepared so that the material can be adapted to the time available.
Another related complication is that the weather forecast has to be a live broadcast; it cannot be pre- recorded. Live shows are very nerve- racking for the presenter because almost anything can go wrong. Perhaps the most worrying aspect for every weather
forecaster is getting the following day’s predictions wrong. Unfortunately for them this is not an unusual occurrence; the weather is not always possible to predict accurately.
The weather is a national obsession in Britain, Perhaps because it is so changeable. It’s the national talking point, and most people watch at least one daily bulletin. It can be mortifying for a weather man or woman who has predicted rain for the morning to wake up to brilliant sunshine. These days, a weather forecaster’s job is even more complicated because they are replied upon to predict other environmental conditions. For example, in the summer the weather forecast has to include the pollen count for hay fever sufferers. Some also include reports on ultraviolet radiation intensity to help people avoid sunburn.
The job of the weather forecaster is certainly far more complicated than just pointing at a map and describing weather conditions. It’s a job for professionals who can cope with stressful and demanding conditions.

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 theories about the beginning of drama in ancient Greece. The one most widely accepted today is based on the assumption that drama evolved from ritual. The argument for this view goes as follows. In the beginning, human beings viewed the natural forces of the world, even the seasonal changes, as unpredictable, and they sought, through various means, to control these unknown and feared powers. Those measures which appeared to bring the desired results were then retained and repeated until they hardened into fixed rituals. Eventually stories arose which explained or veiled the mysteries of the rites. As time passed some rituals were abandoned, but the stories, later called myths, persisted and provided material for art and drama.
Those who believed that drama evolved out of ritual also argue that those rites contained the seed of theater because music, dance, masks, and costumes were almost always used. Furthermore, a suitable site hard to be provided for the performances, and when the entire community did not participate, a clear division was usually made between the "acting area" and the "auditorium". In addition, there were performers, and since considerable importance was attached to avoiding mistakes in the enactment of rites, religious leaders usually assumed that task. Wearing masks and costumes, they often impersonated other people, animals, or supernatural beings, and mimed the desired effect- success in hunt or battle, the coming rain, the revival of the Sun as an actor might. Eventually such dramatic representations were separated from religious activities.
Another theory traces the theater's origin from the human interest in storytelling. According to this view, tales (about the hunt, war or other feats) are gradually elaborated, at first through the use of impersonation, action, and dialogue by a narrator and then through the assumption of each of the roles by a different person. A closely related theory traces theater to those dances that are primarily rhythmical  and gymnastic or that are imitation of animal movements and sounds.

Which of the following is NOT mentioned as a common element of theater and ritual?

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. 
      In the early 1800s, less than 3% of the world's population lived in cities; today, more than half of the global population is urban and by 2050, the proportion will rise to three quarters. There are thousands of small and medium-sized cities along with more than 30 megacities and sprawling, networked metropolitan areas with 15 million residents or more. Yet despite these massive transformations in how people live and interact, our international affairs are still largely dictated by national states, not cities.
       Cities are beginning to flex their muscles on the international stage. They are already displacing nation states as the central nodes of the global economy, generating close to 80% of global GDP. Cities like New York and Tokyo are bigger in GDP terms than many G-20 countries. Metropolitan regions and special economic zones are linking global cities through transnational supply chains. A growing number of mega-regions, such as those linking cities in Mexico and the U.S., transcend borders. In the process, cities are collectively forging common regional plans, trading partnerships, and infrastructure corridors.
      The spectacular rise of cities did not happen by accident. Cities channel creativity, connect human capital, and when well governed, they drive growth. That many cities and their residents are rolling up their sleeves and getting things done - where nations have failed - are grounds for optimism. In the future, we hope that it is our proximate, accountable, and empowered city leaders who will define our fates. 

The phrase "flex their muscles" in paragraph 2 is closest in meaning 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:
Amelia Earhart was born in Kansas in 1897. Thirty one years later, she received a phone call that would change her life. She was invited to become the first woman passenger to cross the Atlantic Ocean in a plane. The flight took more than 20 hours – about three times longer than it routinely takes today to cross the Atlantic by plane. Earhart was twelve years old before she ever saw an airplane, and she didn’t take her first flight until 1920. But she was so thrilled by her first experience in a plane that she quickly began to take flying lessons. She wrote, “As soon as I left the ground, I knew I myself had to fly.”
After that flight Earhart became a media sensation. She was given a ticker tape parade down Broadway in New York and even president Coolidge called to congratulate her. Because her record – breaking career and physical appearance were similar to pioneering pilot and American hero Charles Lindbergh, she earned the nickname “Lady Lindy.” She wrote a book about her flight across the Atlantic, called 20 Hrs, 40 Min.
Earhart continued to break records, and also polised her skills as a speaker and writer, always advocating women’s achievements, especially in aviation. Her next goal was to achieve a transatlantic crossing alone. In 1927 Charles Lindbergh became the first person to make a solo nonstop flight across the Atlantic. Five years later, Earhart became the first woman to repeat that feat. Her popularity grew even more and she was the undisputed queen of the air. She then wanted to fly around the world, and in June 1973 she left Miami with Fred Noonan as her navigator. No one knows why she left behind important communication and navigation instruments. Perhaps it was to make room for additional fuel for the long flight. The pair made it to New Guinea in 21 days and then left for Howland Island, a tiny island in the middle of the Pacific Ocean. The last communication from Earhart and Noonan was on July 2, 1937 with a nearby Coast Guard ship. The United States Navy conducted a massive search for more than two week but no trace of the plane or its passengers was ever found. Many people believe they got lost simply ran out of fuel and died.

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.

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 first thing to do when you have a trip abroad is to check that your passport is valid. Holders of out–of–date passports are not allowed to travel overseas. Then you can prepare for your trip. If you don't know the language, you can have all kinds of problems communicating with local people. Buying a pocket dictionary can make a difference. You'll be able to order food, buy things in shops and ask for directions. It's worth getting one. Also there's nothing worse than arriving at your destination to find there are no hotels available. The obvious way to avoid this is to book in advance. This can save you money too. Another frustrating thing that can happen is to go somewhere and not know about important sightseeing places. Get a guide book before you leave and make the most of your trip. It's a must.
Then, when you are ready to pack your clothes, make sure they are the right kind. It's no good packing sweaters and coats for a hot country or T–shirts and shorts for a cold one. Check the local climate before you leave.
Also, be careful how much you pack in your bags. It's easy to take too many clothes and then not have enough space for souvenirs. But make sure you pack essentials. What about money? Well, it's a good idea to take some local currency with you but not too much. There are conveniently located cash machines (ATMs) in most big cities, and it's usually cheaper to use them than change your cash in banks. Then you'll have more money to spend. When you are at your destination, other travellers often have great information they are happy to share. Find out what they have to say. It could enhance your travelling experience.

According to the passage, you should do all of the following before leaving EXCEPT

Charles Lindbergh was born in Detroit, Michigan, in 1902 but was raised on a farm in Minnesota, where his father was elected to the U.S. Congress in 1907. From then on, he spent his boyhood alternately in Washington, D.C. Detroit, and Little Falls, Minnesota. Because Lindbergh exhibited exceptional mechanical talent, in 1921 he was admitted to the University of Wisconsing to study engineering. However, the young man was seeking more challenging endeavors, and two years later he became a stunt pilot who performed feats at county fairs and public assemblies. This unusual and dangerous undertaking paid off handsomely in the sense that it allowed him to gain a diverse and well–rounded experience in aeronautics. He particularly delighted in what he called “wing–walking” and parachute jumping.
After a year of training as a military cadet, Lindbergh completed his program at the Brooks and Kelly airfields at the top of his class and earned the rank of captain.
Robertson Aircraft Corporation of St. Louis, Missouri, offered him employment as a mail pilot to run the routes between St. Louis and Chicago, and Lindbergh retained his position with the company until 1927. During this period, he set out to win the Raymond B. Orteig prize of $25,000 to be awarded to the first pilot to fly nonstop from New York to Paris. This ambition would irreversibly change his life and accord him a prominent place in the history of aviation.
Embarking on the greatest adventure of his time, Lindbergh left Roosevelt Field at 7:52 A.M. on May 20, 1927, and landed at Le Bourget Field at 5:24 P.M. the next day. Fearing that he would be unknown when he arrived, Lindbergh carried letters of introduction to dignitaries in Paris, but when his plane came to a stop, he was overwhelmed by tremendous welcoming crowds. He was decorated in France, Great Britain, and Belgium, and President Coolidge sent a specially designated cruiser, the Memphis, to bring him back, His accomplishments in aeronautics brought him more medals and awards than had ever been received by any other person in private life.

The author of the passage implies that Lindbergh’s job with Robertson Aircraft Corporation.

Called the ‘Red Planet,’ Mars is roughly half the size of Earth, and one of our closest neighboring planets. Though Mars is the most Earth-like of any other planet, the two are still worlds apart. Living on Mars has been the stuff of science fiction for decades. However, can humans really live on Mars? Will it ever be possible or safe? NASA (the National Aeronautics and Space Administration) hopes to find out. NASA researchers on Earth are conducting several experiments together with the International Space Station (ISS) to study the health and safety issues that may tell us if life on Mars is possible.
Food and oxygen would be the main necessities for travelers living extended periods on Mars. The need to grow plants, which provide both food and oxygen, would be a key. But the decreased gravity and low atmospheric pressure environment of the planet will stress the plants and make them hard to grow. However, space station crews are growing plants in controlled environments in two of the station’s greenhouses. They take care of the plants, photograph them, and collect samples to be sent back to Earth. Researchers then use the data to develop new techniques that will make it possible to grow plants successfully in space. 
Another concern for space travelers is the health hazards posed by the effect of space radiation on humans. A spacecraft traveling to Mars would be exposed to large amounts of radiation. Since human exposure to such intense radiation would mean certain death, the spacecraft used for such travel would have to protect the humans on the inside of the craft from exposure. Researchers are using special machines inside the crew areas of the International Space Station to carefully watch radiation levels. NASA scientists, who have maintained radiation data since the beginning of human space flight, continue to learn about the dangers it poses. Researchers use the station to test materials that could be used in making a spacecraft that could successfully travel to Mars.
Will it ever be safe for humans to live on Mars? It is still too early to say. But thanks to the dedicated researchers of NASA and the results of ISS experiments, we are getting closer to knowing every day. 
(Adapted from “Select Readings –Intermediate Tests” by Linda Lee and Erik Gundersen)

As mentioned in paragraph 2, why can’t people grow plants successfully in space?

If you go back far enough, everything lived in the sea. At various points in evolutionary history, enterprising individuals within many different animal groups moved out onto the land, sometimes even to the most parched deserts, taking their own private seawater with them in blood and cellular fluids. In addition to the reptiles, birds, mammals and insects which we see all around us, other groups that have succeeded out of water include scorpions, snails, crustaceans such as woodlice and land crabs, millipedes and centipedes, spiders and various worms. And we mustn't forget the plants, without whose prior invasion of the land, none of the other migrations could have happened.
Moving from water to land involved a major redesign of every aspect of life, including breathing and reproduction. Nevertheless, a good number of thoroughgoing land animals later turned around, abandoned their hard-earned terrestrial re-tooling, and returned to the water again. Seals have only gone part way back. They show us what the intermediates might have been like, on the way to extreme cases such as whales and dugongs. Whales [including the small whales we call dolphins] and dugongs, with their close cousins, the manatees, ceased to be land creatures altogether and reverted to the full marine habits of their remote ancestors. They don't even come ashore to breed. They do, however, still breathe air, having never developed anything equivalent to the gills of their earlier marine incarnation. Turtles went back to the sea a very long time ago and, like all vertebrate returnees to the water, they breathe air. However, they are, in one respect, less fully given back to the water than whales or dugongs, for turtles still lay their eggs on beaches.
There is evidence that all modern turtles are descended from a terrestrial ancestor which lived before most of the dinosaurs. There are two key fossils called Proganochelys quenstedti and Palaeochersis talampayensis dating from early dinosaur times, which appear to be close to the ancestry of all modern turtles and tortoise. You might wonder how we can tell whether fossil animals lived in land or in water, especially if only fragments are found. Sometimes it's obvious. lchthyosaurs were reptilian contemporaries of the dinosaurs, with fins and streamlined bodies. The fossils look like dolphins and they surely lived like dolphins, in the water. With turtles it is a little less obvious. One way to tell is by measuring the bones of their forelimbs
