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.

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:
Mark Zuckerberg was born in 1984, in New York, into a prosperous, professional family. He developed an interest in computers at an early age and when he was twelve, he created a messaging program which he named "Zucknet". His dentist father used it in his surgery so that his receptionist could inform him of the arrival of a patient without yelling across the room. Together with his  friends, Mark spent much of his spare time as a boy designing and making computer games just for fun.
In 2002, Mark enrolled at Harvard University. By his second year at the institution, he had acquired a reputation on the campus as a developer of software. It was at that time he invented "Facemash" which compared pictures of female students and allowed users to vote on which one   was the most attractive. The program became very popular on campus, but was later shut down by the university authorities who deemed it 'inappropriate'.
Based on the buzz of "Facemash", three of Mark's fellow students, Divya  Narendra, and  twins, Cameron and Tyler Winklevoss, asked him to work with them on an idea for a social networking site called "Harvard Connection". This site was designed to use information from Harvard's student networks to create a dating site for the university's elite. Mark was initially enthusiastic about the complex project but boredom soon set in
and he backed out of it to work on his own social networking site. He created a  site that allowed  users to produce their own profiles, upload photos, and communicate with other people beyond the confines of the university. He called the site "Facebook" and he operated from one small college room until June 2004 when he finally abandoned his studies to  devote himself fully to Facebook and  moved the company to California. By the end of 2004, Facebook had one million users and Mark was climbing high.

Choose the option that best completes each of the following sentences

Computer programmer David Jones earns £35,000 a year designing new computer games, yet he cannot find a bank prepared to let him have a cheque card. Instead, he has been told to wait another two years, until he is 18.

The 16-year-old works for a small firm in Liverpool, where the problem of most young people of his age is finding a job. David's firm releases two new games for the expanding home computer market each month.

But David's biggest headache is what to do with his money.

Despite his salary, earned by inventing new programs within tight schedules, with bonus payments and profit-sharing, he cannot drive a car, take out a mortgage, or obtain credit cards. He lives with his parents in their council house in Liverpool, where his father is a bus driver. His company has to pay £150 a month in taxi fares to get him the five miles to work and back every day because David cannot drive.

David got his job with the Liverpool-based company four months ago, a year after leaving school with six O-levels and working for a time in a computer shop. "I got the job because the people who run the firm knew I had already written some programs," he said.

"I suppose £35,000 sounds a lot but actually that's being pessimistic. I hope it will come to more than that this year." He spends some of his money on records and clothes, and gives his mother £20 a week. But most his spare time is spent working.

"Unfortunately, computing was not part of our studies at school," he said. "But I had been studying it in books and 'magazines for four years in my spare time. I knew what I wanted to do and never considered staying on at school. Most people in this business are fairly young, anyway."

David added: "I would like to earn a million and I suppose early retirement is a possibility. You never know when the market might disappear."

Why does David think he might retire early?

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.

It weighed about 10,000 tons, entered the atmosphere at a speed of 64,000 km/h and exploded over a city with a blast of 500 kilotons. But on 15 February 2013, we were lucky. The meteorite that showered pieces of rock over Chelyabinsk, Russia, was relatively small, at only about 17 metres wide. Although many people were injured by falling glass, the damage was nothing compared to what had happened in Siberia nearly one hundred years ago. Another relatively small object (approximately 50 metres in diameter) exploded in mid–air over a forest region, flattening about 80 million trees. If it had exploded over a city such as Moscow or London, millions of people would have been killed.
By a strange coincidence, the same day that the meteorite terrified the people of Chelyabinsk, another 50m–wide asteroid passed relatively close to Earth. Scientists were expecting that visit and know that the asteroid will return to fly close by us in 2046, but the Russian meteorite earlier in the day had been too small for anyone to spot.
Most scientists agree that comets and asteroids pose the biggest natural threat to human existence. It was probably a large asteroid or comet colliding with Earth which wiped out the dinosaurs about 65 million years ago. An enormous object, 10 to 16 km in diameter, struck the Yucatan region of Mexico with the force of 100 megatons. That is the equivalent of one Hiroshima bomb for every person alive on Earth today.
Many scientists, including the late Stephen Hawking, say that any comet or asteroid greater than 20 km in diameter that hits Earth will result in the complete destruction of complex life, including all animals and most plants. As we have seen, even a much smaller asteroid can cause great damage.
The Earth has been kept fairly safe for the last 65 million years by good fortune and the massive gravitational field of the planet Jupiter. Our cosmic guardian, with its stable circular orbit far from the sun, sweeps up and scatters away most of the dangerous comets and asteroids which might cross Earth’s orbit. After the Chelyabinsk meteorite, scientists are now monitoring potential hazards even more carefully but, as far as they know, there is no danger in the foreseeable future.

It can be inferred from the 1st paragraph that the Siberian meteorite     .

      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.

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.

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.

'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.’

After meeting Eukhtuul, Samantha felt     .

It is 2025. Your mobile is now much more than just a Communication device – more like a remote control for your life. You still call it a "mobile" from habit, but it is an organiser, entertainment device, payment device and security centre, all developed and manufactured by engineers.
On a typical day it will start work even before you wake. Because it knows your travel schedule it can check for problems on the roads or with the trains and adjust the time it wakes you up accordingly, giving you the best route into work. It can control your home, re-programming the central heating if you need to get up earlier and providing remote alerts if the home security system is triggered. It is your payment system - just by placing the phone near a sensor on a barrier, like the Oyster card readers in use on London transport, you can pay for tickets for journeys or buy items in shops. With its understanding of location, the mobile can also provide directions, or even alert the user to friends or family in the Vicinity.
It is your entertainment centre when away from home. As well as holding all your music files, as some phones today are able to do, it will work with your home entertainment system while you sleep to find programmes that will interest you and download them as a podcast to watch on the train or in other spare moments. It will intelligently work out what to do with incoming phone calls and messages.

Around the year 1500, hunting people occupied the entire northern third of North America. They lived well from the animals with which they shared these lands. Hunters of sea mammals had colonized the Arctic coasts of Canada and Greenland between four and five thousand years before. Land-hunting people had lived throughout much of the northern interior for at least 12,000 years.
Northern North America is part of a larger circumpolar ecological domain that continues across the narrow Bering Strait into Siberia and northern Europe. The overall circumpolar environment in the 1500's was not very different from the environment of the present. This vast landmass had a continental climate and was dominated by cold arctic air throughout a long winter and spring season. Summer temperature ranged from near freezing to the mid-20's Celsius, while winter temperature were often as low as 40 degrees below zero Celsius.
Geographers divide the overall circumpolar domain into two zones, the Arctic and, below it, the Subarctic. They refer to the landforms of these areas as tundra and taiga, respectively.
Temperatures in the northern lands were below freezing for eight or nine months of the year. Subsurface soil in the Arctic's tundra remained permanently frozen. Even when summer temperatures were above freezing and the top inches of earth became saturated with water, the soil below remained frozen into a permafrost, as hard as rock. When water flowed upon the surface of permanently frozen tundra, it made overland travel extremely difficult. Summer travel in the boggy lands, or muskeg country, of the Sub Arctic’s taiga was also slow and arduous. Tracking animals was more difficult than it was during the winter when the swampy ground was frozen solid and covered with snow. In both tundra and taiga, hordes of mosquitoes and biting flies bred in the standing pools of water. Clothing lost its thermal efficiency when it became damp. Northern people looked forward to the turn of the season to bring the easier traveling conditions associated with cold weather. In the Arctic, they could haul food and supplies by dogsled while in the Subarctic; people could travel quickly and efficiently by snowshoes and toboggan.

All of the following are mentioned as having made travel in the summer difficult EXCEPT

In many ways, the increasingly rapid pace of climate change is a direct result of the growth of the human population. In the last 100 years, the world population has more than tripled, from just under 2 billion at the beginning of the century to nearly 7 billion today. In addition, the average person uses more energy and natural resources than the average person one hundred years ago, meaning that the rates of consumption are actually much higher than just the increase in population would imply. For example, it took the world 125 years to use the first one trillion barrels of oil. The next trillion barrels will be used in less than 30 years, which is almost 5 times as fast, not three.
All of these activities: food production, energy usage, and the use of natural resources, contribute to climate change in some way. The greater amounts of oil and other fuels burned to create energy release chemicals which add to global warming. In order to produce more food, farmers cut down trees to gain more land for their fields. In addition, we cut down trees to build the houses needed for a larger population. Those trees are an essential part of controlling global warming; others are too numerous to mention.
In addition to a growing population, the world also has a population that desires a higher standard of living than in the past, and a higher standard of living requires the use of even more natural resources. A look at one country will provide a clear example of this fact. China is the world’s most populous nation, with 1.3 billion people. Currently, the standard of living for most of those people is far below that of people in first world nations. Therefore, the average Chinese citizen uses far fewer natural resources and less energy than the average citizen of the US or Japan. But China is growing in power, and more of its citizens are beginning to expect a first world lifestyle. If every Chinese person attains a first world lifestyle, the amount of energy and natural resources needed in the world will double, even if the standard of living in every other nation on Earth remains the same as it is today.

According to the passage, how does the standard of living affect global warming?

   In 1981, the Association of Zoos and Aquariums (AZA) created a Species Survival Plan (SSP) in order to help preserve specific endangered and threatened species through captive breeding. With over 450 SSP Plans, there are a number of endangered species that are covered by the AZA with plans to cover population management goals and recommendations for breeding for a diverse and healthy population, created by Taxon Advisory Groups. These programs are commonly created as a last resort effort. SSP Programs regularly participate in species recovery, veterinary care for wildlife disease outbreaks, and a number of other wildlife conservation efforts. The AZA's Species Survival Plan also has breeding and transfer programs, both within and outside of AZA - certified zoos and aquariums. Some animals that are part of SSP programs are giant pandas, lowland gorillas, and California condors.

Robots are useful for exploring and working in space. In particular, many robots have been sent to explore Mars. Such robots have usually looked like a box with wheels. Though these robots are useful, by their very nature they are unreliable, extremely expensive, and they break easily. Also, they cannot do very many tasks. Because of these problems, scientists have been developing a new and unusual kind of robot. These new robots move like snakes, so they have been given the name "snakebots."
The way a snake is shaped lets it get into very small spaces, like cracks in rocks. It can also push its way below the ground or climb up different kinds of objects, like high rocks and trees. Such abilities account for the usefulness of a robot designed like a snake. A snakebot would be able to do these things, too, making it much more effective than regular robots with wheels, which easily get stuck or fall over. Since they can carry tools, snakebots would be able to work in space, as well. They could, for example, help repair the International Space Station.
But how can such a robot shape be made? A snakebot is built like a Chain made of about thirty parts, or modules. Each module is basically the same in that they all have a small computer and a wheel to aid movement. The large computer in the "head” of the snake makes all of the modules in a snakebot work together.
The modular design of the snakebot has many advantages. If one module fails, another can be added easily. Snakebot modules can also carry different kinds of tools, as well as cameras. Since each module is actually a robot in itself, one module can work apart from the rest if necessary. That is, all the modules can separate and move on their own, and then later, reconnect back into a larger robot.
Researchers are also trying to develop snakebots made of a special kind of plastic that can change its shape using electricity, almost like animal muscles. Snakebots made with this plastic will be very strong and hard to break.
Overall, the snakebot design is much simpler than that of common robots. Thus, snakebots will be much less expensive to build. For example, a robot recently sent to Mars cost over a hundred million dollars, whereas snakebots can cost as little as a few hundred dollars. With their versatility and affordability, snakebots seem to be the wave of the future, at least as far as space robots are concerned.

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:
A leading question among anthropologists is: what exactly led to the development of human cities? Basically, modern humans have existed on earth for over 100,000 years. Yet it is only in the last 8,000 years that they have begun to gather in significant numbers and form cities. Prior to that period, humans existed in small family or tribal groups, generally consisting of fewer than 100 individuals. What, then, led humans to make the dramatic shift from living in small groups to living in large, organized cities? It seems that the development of cities required a particular set of circumstances.
First, it required a minimum population density. For much of their early history, humans existed only in small numbers. This is due to the fact that early humans relied on hunting and gathering wild foods for their survival. Even the most fertile land would only support a relatively small number of predators, so it was not until humans began to practice agriculture that they were able to gather in large enough numbers to form cities.
Furthermore, the development of a city could only be possible if a large number of people shared a common language, culture and religion. Without such unifying factors, a cooperative, peaceful existence among large numbers of people would have been impossible.
Finally, it seems that early humans needed to be faced with a large problem, which one small group of individuals could not solve on its own. Only when large-scale cooperation was needed to overcome a problem would humans come together to form cities.

The word "circumstances" in paragraph 1 mostly means     .
