      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 3, what would happen if the Earth were bereft of natural greenhouse gases?

Today we take electricity for granted and perhaps we do not realize just how useful this discovery has been. Steam was the first invention that replaced wind power. It was used to drive engines and was passed through pipes and radiators to warm rooms. Petrol mixed with air was the next invention that provided power. Exploded in a cylinder, it drove a motor engine. Beyond these simple and direct uses, those forms have not much adaptability. On the other hand, we make use of electricity in thousands of ways. From the powerful voltages that drive our electric trains to the tiny current needed to work a simple calculator, and from the huge electric magnet in steel works that can lift 10 tons to the tiny electric magnet in a doorbell, all are powered by electricity. An electric current can be made with equal ease to heat a huge mass of molten metal in a furnace or to boil a jug for a cup of coffee. Other than atomic energy, which has not as yet been harnessed to the full, electricity is the greatest power in the world. It is flexible, and so adaptable for any task for which it is wanted. It travels so easily and with incredible speed along wires or conductors that it can be supplied instantly over vast distances. To generate electricity, huge turbines or generators must be turned. In Australia they use coal or water to drive this machinery. When dams are built, falling water is used to drive the turbines without polluting the atmosphere with smoke from coal. Atomic power is used in several countries but there is always the fear of an accident. A tragedy once occurred at Chernobyl, in Ukraine, at an atomic power plant used to make electricity. The reactor leaked, which caused many deaths through radiation. Now scientists are examining new ways of creating electricity without harmful effects to the environment. They may harness the tides as they flow in and out of bays. Most importantly, they hope to trap sunlight more efficiently. We do use solar heaters for swimming pools but as yet improvement in the capacity of the solar cells to create more current is necessary. When this happens, electric cars will be viable and the world will rid itself of the toxic gases given off by trucks and cars that burn fossil fuels.

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.

What we today call American folk art was, indeed, art of, by, and for ordinary, everyday “folks” who, with increasing prosperity and leisure, created a market for art of all kinds, and especially for portraits. Citizens of prosperous, essentially middle-class republics — whether ancient Romans, seventeenth-century Dutch burghers, or nineteenth-century Americans — have always shown a marked taste for portraiture. Starting in the late eighteenth century, the United States contained increasing numbers of such people, and of the artists who could meet their demands. The earliest American folk art portraits come, not surprisingly, from New England — especially Connecticut and Massachusetts — for this was a wealthy and populous region and the center of a strong craft tradition. Within a few decades after the signing of the Declaration of Independence in 1776, the population was pushing westward, and portrait painters could be found at work in western New York, Ohio,
Kentucky, Illinois, and Missouri. Midway through its first century as a nation, the United States' population had increased roughly five times, and eleven new states had been added to the original thirteen. During these years the demand for portraits grew and grew eventually to be satisfied by the camera. In 1839 the daguerreotype was introduced to America, ushering in the age of photography, and within a generation the new invention put an end to the popularity of painted portraits. Once again an original portrait became a luxury, commissioned by the wealthy and executed by the professional.
But in the heyday of portrait painting — from the late eighteenth century until the
1850's — anyone with a modicum of artistic ability could become a limner, as such a portraitist was called. Local craftspeople — sign, coach, and house painters — began to paint portraits as a profitable sideline; sometimes a talented man or woman who began by sketching family members gained a local reputation and was besieged with requests for portraits; artists found it worth their while to pack their paints, canvases, and brushes and to travel the countryside, often combining house decorating with portrait painting.

According to the passage, which of the following contributed to a decline in the demand for painted portrait?

Most people need some preparation before they are ready for the workforce, and planning should begin long before it is time to start a career.
Many high school students don't yet know what they want to do. High school is a great time to start thinking about careers. Settling on just one occupation in high school isn't necessary, but they should know how to explore careers and put time into investigating them and learning about their skills and interests.
Understanding what you enjoy what you are good at is the first step in exploring careers. It is important to think about what you like to do because work will eventually be a big part of your life. Once you have thought about the subjects and activities you like best, the next step is to look for careers that put those interests to use. If you love sports, for example, you might consider a career as a gym teacher, or coach.
Another approach to identifying potential career interests is to consider local employers and the types of jobs they have. There are many jobs in manufacturing and healthcare near the high school. Talking directly to workers can help you get information about what they do. If you don't know workers in occupations that interest you, ask people such as your parents, friends, or teacher for their contacts.
If job shadowing give you taste of what an occupation is like, imagine how helpful getting experience could be. Students can begin getting career-related experiences in high school through internships, employment, and other activities. Completing an internship is an excellent way to get experience. Internships are temporary, supervised assignments designed to give student practical job training.

The word “manufacturing” in paragraph 4 means     .

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:
We first learn about loving and caring relationships from our families. Family is  defined as   a domestic group of people with some degree of kinship - whether through blood, marriage, or adoption. Ideally, each child is nurtured, respected, and grows up to care for others and develop strong and healthy relationships. This does not mean that it is always easy to make and keep friends; it just means that we share the goal of having strong relationships.
"Family" includes your siblings and parents, as well as relatives who you may not interact with every day, such as your cousins, aunts, uncles, grandparents, and stepparents.
These are probably the people you are closest to and with whom you spend the most time.  Having healthy relationships with your family members is both important and difficult.
Families in the 21st century come in all shapes and sizes: traditional, single parent, blended  (more than one family together in the same house], and gay and lesbian parents -just to name a few. No matter the "type" of family you have, there are going to be highs and lows - good times and bad. Many times, however, families become blocked in  their relationships by  hurt, anger, mistrust, and confusion. These are natural and normal, and few families do not have at  least  a  few experiences with them. The worst time for most families, is during a divorce. By making a few  simple changes in the way we look at the world and deal with other people, it is possible to create happier, more stable relationships. Families need to be units of mutual caring and support; they can   be sources of lifelong strength for all individuals.

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."

People in the UK enjoy fewer years of good health before they die than the citizens of most comparable European countries as well as Australia and Canada, a major report shows. While life expectancy has improved by 4.2 years in the UK over the two decades, other countries have improved faster. In 2010, Spain topped the league. Its people could expect 70.9 years of healthy life - before disease and disability began to take a toll. Second came Italy, with 70.2 years and third was Australia, on 70.1 years. In the UK, we can expect 68.6 healthy years of life.
Hunt said the UK was a long way behind its global counterparts and called for action by local health commissioners to tackle the five big killers - cancer, heart disease, stroke, respiratory and liver diseases. Drinking and drug use have been the main issues behind the worsening of the UK's ranking in early deaths among adults aged 20-54. In 2010, drugs were the sixth leading cause of death in this age group and alcohol was 18th - up from 32nd and 43rd place respectively 20 years earlier.
Hunt will on Tuesday announce a strategy to tackle cardiovascular disease, which he says could save 30,000 lives a year. "Despite real progress in cutting deaths, we remain a poor relative to our global cousins on many measures of health, something I want to change," he said. "For too long we have been lagging behind and I want the reformed health system to take up this challenge and turn this shocking underperformance around.” However, the problem is only in part to do with hospital care - much of it is about the way we live. Our diet, our drinking and continuing smoking habits all play a part, which assumes its responsibilities on 1 April.

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:
Urban populations interact with their environment. Urban people change their  environment through their consumption of Food, energy, water, and land. And in turn, the polluted urban environment affects the health and quality of life of the urban population. People who live in urban areas have very different consumption patterns than residents in rural areas. For example, urban populations consume much more food, energy, and durable goods than rural populations. In China during the 1970s, the urban populations consumed twice as much pork as the rural populations who were raising the pigs. With economic development,  the difference  in  consumption declined as the rural populations ate better diets. But even a decade later, urban populations had 60 percent more pork in their diets than rural populations. The increasing consumption of meat is a sign of growing affluence in Beijing; in India where  many  urban  residents are vegetarians, greater prosperity is seen in higher consumption of milk.
Urban populations not only consume more food, but they also consume more durable goods, In the early 1990s, Chinese households in urban areas were two times more likely to have a   TV, eight times more likely to have a washing machine, and 25 times more likely to have a refrigerator than rural households. This increased consumption is a function of urban labor markets, wages, and household structure.
Urban consumption of energy helps create heat islands that can change local weather patterns and weather downwind from the heat islands. The heat  island  phenomenon is created because cities radiate heat back into the atmosphere at rate 15 percent to 30 percent less than rural areas. The combination of the increased energy consumption and difference in albedo (radiation) means that cities are warmer than rural areas (0.6 to 1.3 C), And these heat islands become traps for  atmospheric pollutants. Cloudiness and fog occur with greater frequency. Precipitation is 5 percent to 10 percent higher in cities; thunderstorms and hailstorms are much  more frequent, but snow days in cities are less common.
Urbanization also affects the broader regional environments. Regions  downwind  from  large industrial complexes also see increases in the amount of precipitation, air pollution, and the number of days with thunderstorms. Urban areas affect not only the weather patterns, but also the runoff patterns for water. Urban areas generally generate more rain, but they reduce the infiltration of water and lower the water tables. This means that runoff occurs more rapidly with greater peak flows. Flood volumes increase, as do floods and water pollution downstream.
Many of the effects of urban areas on the environment are not necessarily linear. Bigger  urban areas do not always create more environmental problems. And small urban areas can cause large problems. Much of what determines the extent of the environmental impacts is how the urban populations behave - their consumption and living patterns - not just how large they are.

Which of the following is TRUE about the food consumption of Chinese urban inhabitants?

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.

These days it is easy for most of us to get a hold of the latest books or magazines. We can go to bookstores, order them through the Internet, or borrow them from the local libraries. Now imagine having to walk miles and miles through a hot sandy desert just to borrow a book. This is the reality for people living in the villages of the Carissa region of Kenya in East Africa.
In 1996, librarian Wycliffe Oluoch used to spend each day waiting for people to come to borrow some of the 24,000 books in his library in Carissa. The library had no shortage of books, but people weren’t coming to read them. It was too much effort to walk through the desert just to borrow books. Oluoch racked his brain for ways to entice people into the library. After a lot of thought, he hit upon a great idea. If people wouldn’t come to the library, then he would have to take the library to them. Oluoch strapped boxes of books onto the backs of camels, and created the Mobile Camel Library.
Starting with three camels in 1996, but more recently expanding the service to six camels, the Mobile Camel Library serves over one million people. Twice a month, the camel library can be seen carrying books all around the Carissa region. These hard-working animals need little water and can carry up to 500 pounds of books across the sands. A librarian, a library assistant, a herdsman, and a lookout all travel with the camels. The lookout helps protect the books from thieves.
The children of Carissa love the camel library and appreciate Oluoch’s effort. Eleven-year-old Mohamud Mohamed reads his library books carefully and always returns them on time. He knows the Carissa library punishes people for losing books, just like any other library. However, the punishment is very stiff compared to that of other libraries. If a village loses a book, the camel library stops visiting.

Which of the following do NOT travel with the Mobile Camel Library?

Last week I went to visit Atlantic College, an excellent private college in Wales. Unusually, it gives people much needed experience of life outside the classroom, as well as the opportunity to study for their exams. The students, who are aged between 16 and 18 and come from all over the word, spend the morning studying. In the afternoon they go out and do a really useful activity, such as helping on the farm, looking after people with learning difficulties, or checking for pollution in rivers.

One of the great things about Atlantic College students is that they come from many different social backgrounds and countries. As few can afford the fees of £20,000 over two years, grants are available.

A quarter of students are British, and many of those can only attend because they receive government help.

“I really admire the college for trying to encourage international understanding among young people", as Barbara Molenkamp, a student from the Netherlands, said. ''You learn to live with people and respect them, even the ones you don't like. During the summer holidays my mother couldn't believe how much less I argued with my sister."

To sum up, Atlantic College gives its students an excellent education, using methods which really seem to work.

The concept of being environmentally conscious, or “green”, has become more prevalent in twenty first-century U.S culture. It has begun to affect the manufacturing of everything from non-toxic household cleaning products to motor vehicles powered by alternative sources of energy. However, one way of being “green” that is perhaps not as apparent to the viewer but of equal importance in being environmentally conscious, is the construction of buildings that are considered “sustainable”. Sustainable buildings are those that do not impose on the environment or rely on the over-utilization of energy or natural resources. There are four main principles of sustainability, which includes consideration of the health and stability of all living things and their environmental diversity, as well as the economic opportunities of humanity.
Sustainable architecture consists of environmentally conscious design techniques. In the past, the demolition of an old building meant that all or most of the debris of the building would end up in a landfill or a waste disposal site. Today, architects can plan and design a building that uses recycled materials, such as wood, concrete, stone, or metal. These materials are salvaged from the demolition of an older building and can be appropriately incorporated into a new construction. Architects and construction supervisors may also choose to recycle more organic parts of demolished buildings, such as wooden doors, windows and other glass, ceramics, paper, and textiles.
A problem that has often arisen has been with how a site crew-whether it is demolition or construction crew determines and sorts what is “waste” and what is recyclable. Architects and environmental scientists have to decide whether or not a material is appropriate for use in new construction and how it will impact the environment. They must evaluate the materials from the demolition and determine what those materials contain, and if they meet the standards set by the U.S, government’s Environmental Protection Agency (the EPA). If the debris from the demolition contains hazardous materials that are harmful to the environment or to the consumer, such as asbestos, then the material is not salvageable. Use of the asbestos for insulation and as a form of fire retardation in buildings and fabrics was common in the nineteenth century. Asbestos was once used in shingles on the sides of buildings, as well as in the insulation in the interior walls of homes or other construction. In new “green” construction, insulation that once asbestos- based can be replaced with recycled denim or constructed with cellulose-a fibrous material found in paper products. The same-assessment applies to wood or wallboard painted with toxic lead-based paints. In addition, gas-flow regulators and meters on both water and gas heating systems constructed prior to 1961 must be carefully evaluated to determine that they do not contain dangerous substances such as mercury. Mercury can be harmful to humans and the environment if it is spilled during the removal of these devices.

In paragraph 2, the word “salvaged” is closest in meaning to     .

Volunteering has been acknowledged as part of the wider health policy, with the NHS five-year plan identifying a need to encourage community volunteering. It also has an important role to play in tackling social exclusion, through projects such as lunch clubs for older people, assisted gardening schemes, or young play leaders.
Volunteering can help to provide people with ways out of poverty, by giving them new skills, confidence and aid social integration. This is of particular value to those who are most excluded from the labour market, such as recent migrants or people with disabilities. But while the benefits of volunteering are clear, there is worrying evidence that the people who could benefit most from giving their time are precisely those least likely to be involved.
There are many reasons for people not to volunteer. For older people, the barriers can include poor health, poverty, lack of skills, poor transport links, or having caring responsibilities, such as looking after grandchildren. Younger people can be deterred by feeling they don’t have the time to volunteer, or not knowing anyone else who volunteers. Many of them also think volunteering is just for older people with time on their hands. Volunteering has an image problem – particularly with men and younger people.
More should be done to promote the value of volunteering to the particular needs of different groups. There is evidence on why people choose to volunteer, and we need to make better use of that information. For instance, a recent survey showed that 95% of young people, aged 13-24, hoped to develop new skills through volunteering, compared to just 32% of volunteers aged over 55. Almost three quarters of young people were keen to gain qualifications through volunteering compared to just 13% of those over 55. Over three quarters of disabled volunteers were keen to develop new skills and nearly two thirds hoped to improve their health and wellbeing through volunteering.

   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.

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:
During the past half-century, our species has embarked on a remarkable social experiment. For the first time in human history, great numbers of people - at all ages, in all places, of every political persuasion - have begun settling down as singletons. Until the second half of the last century, most of us married young and parted only at death. If death came early, we remarried quickly; if late, we moved in with family, or they with us. Now we marry later. We divorce, and stay single for years or decades.
The rise of living alone has produced significant social benefits, too. Young and middle-aged solos have helped to revitalise cities, because they are more likely to spend money, socialise and participate in public life. Contemporary solo dwellers in the US are primarily women: about 18 million, compared with 14 million men. The majority, more than 16 million, are middle-aged adults between the ages of 3S and 64. The elderly account for about 11 million of the total. Young adults between 18 and 34 number increased more than 5 million, compared with 500,000 in 1950, making them the fastest-growing segment of the solo-dwelling population.
Despite fears that living alone may be environmentally unsustainable, solos tend to live in apartments rather than in big houses, and in relatively green cities rather than in car-dependent suburbs. There's good reason to believe that people who live alone in cities consume less energy than if they coupled up and decamped to pursue a single-family home.

In the 2rd paragraph, the writer suggests that     .

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.

The word “consumption” in the passage is closest in meaning to .........

Read the passage then choose the best answer:
Music influences people in different ways or the same person differently at different times.
Music may seem to influence people differently. That is because people can react differently to the
music. We are able to apply a choosing process to the music we hear. If someone hates jazz, then a
jazz piece with a positive effect will probably not make him feel good. A happy song might appear
to make an angry person angrier, yet it is not the music itself that is creating the anger; rather it is the
positive effect of the music. The angry person does not want to accept the song's happy feeling: it
points out his already existing anger, and makes that anger come to the surface. When a piece of
music is played and we are listening to it, our body, mind, and feelings are being affected. The
musicians of ancient cultures such as China, India, Turkey and Greece understood the effects of
music. In fact, Pathagoras, in ancient Greece, introduced a whole science that concerned them.
Because the musicians of these ancient cultures understood these effects, they created music that was
positive, uplifting, and beneficial. Once the effects of music are better understood, the next step is to
gain a better understanding of the music around us, and what effect it is actually having.

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:
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

As mentioned in paragraph 2, which of the following species returned to the water least completely?
