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 following questions:
The ruined temples of Angkor are perhaps one of the most impressive Seven Wonders of the World. Located in modern day Cambodia near Lake Tonle Sap, the largest freshwater lake in Asia, Angkor was the seat of power for the Khmer Empire for the ninth to the fifteenth century. The ruins of Angkor are documented as some of the most impressive ones in the world, rivaling the pyramids of Giza in Egypt. Why this mighty civilization died out is a question that archaeologists are now only beginning to ponder. The answer, it turns out, may be linked with the availability of fresh water.
One possible explanation for the downfall of the Khmer Empire has to do with the inhabitant’s irrigation system. The temples and palaces of Angkor were constructed around a series of artificial reservoirs and canals which were annually flooded to capacity by the Mekong River. Once filled, they were used to irrigate the surrounding paddies and farmland during the course of the year. Farmers were completely dependent on the water for their crucial rice crop. Without consistent irrigation, the farmers would have been unable to maintain functional crop production.
Scientists speculate that toward the end of the Khmer Empire the hydraulic system of the reservoirs and canals broke down. The construction of hundreds of sandstone temples and palaces required an enormous amount of physical labor. In addition, as the capital of Khmer Empire, Angkor contained upwards of one hundred thousand people who resided in and around Angkor. In order to feed so many people, the local farmers were driven to grow food more quickly and more efficiently. After centuries of continual use, the irrigation system was pushed beyond its capacity. Soil erosion, nutrient depletion, and loss of water led to decrease in the food supply. With the less food available, the people of Angkor slowly began to migrate to other parts of Cambodia, thus leaving the marvelous city of Angkor to be swallowed by the jungle. Therefore, it is speculated that the Khmer Empire may have fallen victim to its own decrepit infrastructure.The hydraulic system of reservoirs .

Read the following passage and choose the best answer (A, B, C, D):
Pollutants in the air aren’t always visible and come from many different sources. Smog hanging over cities is the most familiar and obvious form of air pollution. But there are different kinds of pollution - some visible, some invisible - that contribute to global warming. Generally any substance that people introduce into the atmosphere that has damaging effects on living things and the environment is considered air pollution. Carbon dioxide, a greenhouse gas, is the main pollutant that is warming Earth. Though living things emit carbon dioxide when they breathe, carbon dioxide is widely considered to be a pollutant when associated with cars, planes, power plants, and other human activities that involve the burning of fossil fuels such as gasoline and natural gas. In the past 150 years, such activities have pumped enough carbon dioxide into the atmosphere to raise its levels higher than they have been for hundreds of thousands of years. Other greenhouse gases include methane - which comes from such sources as swamps and gas emitted by livestock - and chlorofluorocarbons (CFCs), which were used in refrigerants and aerosol propellants until they were banned because of their deteriorating effect on Earth’s ozone layer. Another pollutant associated with climate change is sulfur dioxide, a component of smog. Sulfur dioxide and closely related chemicals are known primarily as a cause of acid rain. But they also reflect light when released in the atmosphere, which keeps sunlight out and causes Earth to cool. Volcanic eruptions can spew massive amounts of sulfur dioxide into the atmosphere, sometimes causing cooling that lasts for years. In fact, volcanoes used to be the main source of atmospheric sulfur dioxide; today people are. Industrialized countries have worked to reduce levels of sulfur dioxide, smog, and smoke in order to improve people’s health. But a result, not predicted until recently, is that the lower sulfur dioxide levels may actually make global warming worse. Just as sulfur dioxide from volcanoes can cool the planet by blocking sunlight, cutting the amount of the compound in the atmosphere lets more sunlight through, warming the Earth. This effect is exaggerated when elevated levels of other greenhouse gases in the atmosphere trap the additional heat.

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

Swine influenza (also called swine flu, hog flu and pig flu) is an infection of a host animal by any one of several specific types of microscopic organisms called "swine influenza virus". A swine influenza virus (SIV) is any strain of the influenza family of viruses that is usually hosted by (is endemic in) pigs. As of 2009, the known SIV strains are the influenza c virus and the subtypes of the influenza A virus known as HI N1, H1N2, H3N1, H3N2 and H2N3. Swine influenza is common in pigs in the mid-western United States (and occasionally in other states), Mexico, Canada, South America, Europe (including the UK, Sweden and Italy) Kenya Mainland China, Taiwan Japan and other parts of eastern Asia.
Transmission of swine influenza vims from pigs to humans is not common and does not always cause human influenza, often only resulting in the production of antibodies in the blood. The meat of the animal poses no risk of transmitting the virus when properly cooked. If transmission does cause human influenza, it is called zoonotic swine flu. People who work with pigs, especially people with intense exposures, are at increased risk of catching swine flu. In the mid-20th century, identification of influenza subtypes became possible. This allows accurate diagnosis of transmission to humans. Since then, fifty confirmed transmissions have been recorded. Rarely, these strains of swine flu can pass from human to human. In humans, the symptoms of swine flu are similar to those of influenza and of influenza-like illness in general namely chills fever sore throat, muscle pains severe headache, coughing, weakness and general discomfort.
The 2009 flu outbreak in humans known as "swine flu" is due to a new strain of influenza A virus subtype H1N1 that contains genes closely related to swine influenza. The origin of this new strain is unknown. However, the World Organization for Animal Health (OIE) reports that this strain has not been isolated in pigs. This strain can be transmitted from human to human, and causes the normal symptoms of influenza

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

Read the following passage and choose the best answer (A, B, C, D):
For nearly all of human history, there haven’t been that many of us. Around the year zero, Earth’s population is estimated to have been 190 million. A thousand years later, it was probably around 250 million. Then the Industrial Revolution happened, and human population went into overdrive. It took hundreds of thousands of years for humans to hit the 1 billion mark, in 1800. We added the next billion by 1928. In 1960, we hit 3 billion. In 1975, 4 billion. That sounds like the route to an overpopulation apocalypse, right? To many midcentury demographers, futurists, and science fiction writers, it certainly predicted one. Extending the timeline, they saw a nightmarish future ahead for humanity: human civilizations constantly on the brink of starvation, desperately crowded under horrendous conditions, draconian population control laws imposed worldwide. Stanford biologist Paul Ehrlich wrote in his best-selling book, “In the 1970’s, hundreds of millions of people will starve to death” because of overpopulation. None of that ever came to pass. The world we live in now, despite approaching a population of nearly 8 billion, looks almost nothing like the one doomsayers were anticipating. Starting in the 19th century in Britain and reaching most of the world by the end of the 20th century, birthrates plummeted — mostly because of women’s education and access to contraception, not draconian population laws. In wealthy societies where women have opportunities outside the home, the average family size is small; in fact, it’s below replacement level. Called the demographic transition, it is one of the most important phenomena for understanding trends in global development. There’s still significant debate among population researchers about the extent of the sea change in population trends. Researchers disagree on whether global populations are currently on track to start declining by midcentury. There’s also disagreement on what the ideal global population figure would be, or whether it’s morally acceptable to aim for such a figure. While academic research seeks to nail down these questions, it’s important to be clear what is consensus among researchers. Our projections around population are used to make global health and development policy. They’re critical for planning, especially about climate change. Fears of overpopulation sometimes turn into hostility to immigrants, those who choose to have large families, and countries in an earlier stage of their population transition. Having an informed conversation about population is crucial if we are to get humanity’s future right.

Read the following passage and choose the best answer (A, B, C, D):
Leonardo da Vinci was born on April 15, 1452, in the small Tuscan town of Vinci, near Florence. Leonardo was the son of a wealthy Florentine public official and a peasant woman. In the mid- 1460s, the family settled in Florence, where Leonardo was given the best education that Florence could offer. He rapidly advanced socially and intellectually. He was handsome, persuasive in conversation and a fine musician and improviser. About in 1466, he apprenticed as a studio boy to Andrea Del Verrocchio. In Verrocchio’s workshop, Leonardo was introduced to many activities, from the painting of altarpieces and panel pictures to the creation of large sculptural projects. In 1472, he was entered in the painter’s guild of Florence, and in 1476, he was still mentioned as Verrocchio’s assistant. In Verrocchio’s Baptism of Christ, the kneeling angel at the left of the painting is by Leonardo. In 1478, Leonardo became an independent master. His first commission, to paint an altarpiece for the chapel of the Palazzo Vecchino, the Florentine town hall, was never executed. His first large painting, The Adoration of the Magi, left unfinished, was ordered in 1481 for the Monastery of San Donato a Scopeto, Florence. Other works ascribed to his youth are the so-called Benois Madonna, the portrait Ginerva de’ Benci, and the unfinished Saint Jerome. In 1482, Leonardo’s career moved into high gear when he entered the service of the duke of Milan, Ludovico Sforza, having written the duke an astonishing letter in which he stated that he could build portable bridges; that he knew the techniques of constructing bombardments and of making cannons; that he could build ships as well as armored vehicles, catapults, and other war machines; and that he could execute sculpture in marble, bronze, and clay. He served as a principal engineer in the duke’s numerous military enterprises and was so active also as an architect. In addition, he assisted the Italian mathematician Luca Pacioli in the celebrated work Divina Proportione. Evidence indicates that Leonardo had apprentices and pupils in Milan, for whom he probably wrote the various texts later compiled as Treatise on Painting. The most important of his own paintings during the early Milan period was The Virgin of the Rocks, two versions of which exist; he worked on the compositions for a long time, as was his custom, seemingly unwilling to finish what he had begun. From 1495 to 1496, Leonardo labored on his masterpiece, The Last Super, a mural in the refectory of the Monastery of Santa Maria Delle Grazie, Milan. Unfortunately, his experimental use of oil on dry plaster was technically unsound, and by 1500 its deterioration had begun. Since 1726 attempts have been made, unsuccessfully, to restore it; a concerted restoration and conservation program, making use of the latest technology, was begun in 1977 and is reversing some of the damage. Although much of the original surface is gone, the majesty of the composition and the penetrating characterization of the figures give a fleeting vision of its vanished splendor. During his long stay in Milan, Leonardo also produced other paintings and drawings, most of which have been lost theater designs, architectural drawings, and models for the dome of Milan Cathedral. His largest commission was for a colossal bronze monument to Francesco Sforza, father of Ludovico, in the courtyard of Castello Sforzesco. In December 1499, however, the Sforza family was driven from Milan by French forces; Leonardo left the statue unfinished and he returned to Florence in 1500.

Read the following passage and choose the best answer (A, B, C, D):
It’s extremely important for kids of middle childhood to continue, or to start to lead a healthy lifestyle, including eating nutritious meals as well as getting plenty of exercise and adequate sleep every day. These positive health habits will help children grow strong, stay healthy, and decrease the likelihood that they will become obese. Childhood obesity rates have increasing dramatically in recent years. According to the Centers for Disease Control, in 2004, 18.8% of school-aged children were obese, versus 4% of children 30 years before in 1974. Children’s skyrocketing rate of obesity is worrisome because it greatly increases children’s risk for remaining obese in adulthood, which in turn raises their risk for heart disease, stroke, cancer, diabetes, and premature death as adults. Obese children may also develop associated health problems during the middle childhood stage, such as high blood pressure, high cholesterol levels, and respiratory problems. Obesity can also set the stage for problems with self esteem, depression, anxiety and social ostracism, and/or being victimized by bullies Healthy diet and adequate exercise are important in preventing Type II diabetes in childhood as well as obesity. Diabetes is a metabolic disease in which the body cannot properly metabolize the sugars from food. Because the body cannot metabolize sugars, the sugars accumulate in the bloodstream instead and ultimately stress children’s kidneys, heart, circulatory system, and eyes. Insulin, which is created in the pancreas, is the chemical that breaks down blood sugar. In Type II diabetes, the body does not produce enough insulin to deal with all the sugars coming into the body. This medical diagnosis used to be called “adult-onset diabetes” because the disorder primarily affected adults with poor eating and activity habits. Today, however, this illness is now diagnosed in America’s children far more than in adults. It is now referred to as “Type II diabetes”, to reflect this shift in prevalence. In contrast to the many youth in America who overeat and don’t get enough exercise, other children become obsessed with over-controlling their food intake and with exercising too much. With the constant barrage of perfect, photoshopped bodies in the media today, many children are feeling pressure at younger and younger ages to imitate those images. Children as young as 6 are reporting that they are trying to lose weight by dieting. Overemphasis on extreme thinness can put children at risk for poor self-esteem, unhealthy exercise patterns, and eating disorders such as anorexia and bulimia. Children who embrace healthy eating and exercise habits during middle childhood will have a much easier time maintaining a healthy lifestyle through adolescence and adulthood than individuals who try to make the shift later in life. Teaching children to habitually eat moderate portion sizes and to choose healthy foods in preference to junk foods becomes increasingly important as children begin to spend more time away from home and gain more independence over their food and activity choices. Even though parents have less control over their children’s eating habits during middle childhood than when children were younger, it remains vital that parents continue to reinforce children’s healthy habits whenever possible.

Read the following passage and choose the best answer (A, B, C, D):
Technology continually disrupts almost every area of our lives, resulting in constant shifts across all segments of our society. The education sector is no exception. In fact, the nature of its target audience – mostly young and highly connected – means that the sector must adapt to accommodate their expectations. Most students have grown up online and will expect the same levels of technology in their learning environments as in their day-to-day lives Creating an effective digital learning environment is not just about offering convenience and familiarity to students, however. The consequences for their futures if we don’t keep pace are manifold and damaging. Lack of opportunity is one major threat, because limited or no access to technology will result in a greater divide between certain categories of student. Crucially, students’ potential success could be severely compromised by lack of technical proficiency. As a minimum, employers want graduates who are adept at using technology to connect, communicate, and collaborate with workplace technology. Yet with the right technology platform, solutions and industry partners, universities are starting to create next-generation learning environments that effectively prepare students for the future by offering access to the tools they need while also providing a fulfilling learning experience. Digital technology can supply the framework to support new learning approaches that engage students, bolster new revenue streams, cut operational costs and preserve highly valued school and university brands and reputations. For example, the ability to connect with outside experts or even lecturers with other schools and universities could increase the number of courses offered and attract more students. For both students and teachers, ubiquitous connectivity facilitates greater collaboration, enabling people to develop increasingly connected communities in their chosen fields. Being more available to students can also empower teachers to deliver more innovative, exciting lectures, whether face-to-face or online, while offering more personalised feedback and mentoring. It’s now easier for students to engage on their own terms and no longer having to travel across campus for every single meeting makes it easier for leaders and faculty members to work together, too. Effective digital transformation isn’t just about technology, though. It requires a willingness to adopt technology in new ways, beyond administrative process. It must be continual and evolutionary in order to enhance teaching and learning and improve efficiency. It also necessitates collaborative working; vision and leadership; culture; process and methodology – and the technology itself.
2. According to paragraph 1, what possibly causes students’ demand for high-tech education? -
In the mid - nineteenth century, the United States had tremendous natural resources that could be exploited in order to develop heavy industry. Most of the raw materials that are valuable in the manufacture of machinery, transportation facilities, and consumer goods lay ready to be worked into wealth. Iron, coal, and oil - the basic ingredients of industrial growth - were plentiful and needed only the application of technical expertise, organizational skill, and labor.
One crucial development in this movement toward industrialization was the growth of the railroads. The railway network expanded rapidly until the railroad map of the United States looked like a spider's web, with the steel filaments connecting all important sources of raw materials, their places of manufacture, and their centers of distribution. The railroads contributed to the industrial growth not only by connecting these major centers, but also by themselves consuming enormous amounts of fuel, iron, and coal.
Many factors influenced emerging modes of production. For example, machine tools, the tools used to make goods, were steadily improved in the latter part of the nineteenth century - always with an eye to speedier production and lower unit costs. The products of the factories were rapidly absorbed by the growing cities that sheltered the workers and the distributors. The increased urban population was nourished by the increased farm production that, in turn, was made more productive by the use of the new farm machinery. American agricultural production kept up with the urban demand and still had surpluses for sale to the industrial centers of Europe.
The labor that ran the factories and built the railways was recruited in part from American farm areas where people were being displaced by farm machinery, in part from Asia, and in part from Europe. Europe now began to send tides of immigrants from eastern and southern Europe - most of whom were originally poor farmers but who settled in American industrial cities. The money to finance this tremendous expansion of the American economy still came from European financiers for the most part, but the American were approaching the day when their expansion could be financed in their own " money market".

Is cake a socially awkward person’s reward for having made it through the birthday celebration ritual? Well, not exactly. And actually celebrating the anniversary of one’s birth has not always been the done thing either. What if I told you that having your birthday celebrated is the closest you are getting to be a god(dess)? The first “birthday” celebration goes back to the Egyptians who, each year, would rejoice on the anniversary of the pharaoh’s coronation day. The reason being that you were not really born until you were made into a pharaoh, i.e., after you were transformed into a God. From there, the Greeks contributed to bringing a moon-shaped cake and candles to celebrate the lunar goddess, Artemis, to represent the radiance of the moon and her beauty. But still, what about the cake? We have to thank the Germans for introducing the contemporary birthday celebrations, which included a cake. They started the ‘kinderfeste’, where children were honoured with a celebration on their birthday, especially when it came to the first birthday. Kids also had candles on their cake; one for each year they had been alive, plus one, symbolising the chance of making it through the coming year. Fortunately, we now live at a time where birthday cakes come in various shapes, colours and flavours to please different preferences and dietary requirements, as it is very difficult to imagine a birthday party without a sweet and yummy, treat. Conversely, cake eating is less and less reserved to birthdays only, and personally I really like being able to enjoy a piece of cake whenever I feel like it outside birthday parties. Still, there is something even more special about a birthday cake; it is also about sharing special moments with loved ones

Read the following passage and choose the best answer (A, B, C, D):
Geothermal energy is the heat from the Earth. It’s clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth’s surface, and down even deeper to the extremely high temperatures of molten rock called mác-ma. Almost everywhere, the shallow ground or upper 10 feet of the Earth’s surface maintains a nearly constant temperature between 50° and 60°F (10° and 16°C). Geothermal heat pumps can tap into this resource to heat and cool buildings. A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building. In the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system. In the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger. The heat removed from the indoor air during the summer can also be used to provide a free source of hot water. In the United States, most geothermal reservoirs of hot water are located in the western states, Alaska, and Hawaii. Wells can be drilled into underground reservoirs for the generation of electricity. Some geothermal power plants use the steam from a reservoir to power a turbine/generator, while others use the hot water to boil a working fluid that vaporizes and then turns a turbine. Hot water near the surface of Earth can be used directly for heat. Direct-use applications include heating buildings, growing plants in greenhouses, drying crops, heating water at fish farms, and several industrial processes such as pasteurizing milk. Hot dry rock resources occur at depths of 3 to 5 miles everywhere beneath the Earth’s surface and at lesser depths in certain areas. Access to these resources involves injecting cold water down one well, circulating it through hot fractured rock, and drawing off the heated water from another well. Currently, there are no commercial applications of this technology. Existing technology also does not yet allow recovery of heat directly from mác-ma, the very deep and most powerful resource of geothermal energy

Light, litter and noise from boating and water sports are all major stressors on marine life, a new study aims to enhance our knowledge of the effects of these stressors. Researchers will be gathering data from sporting events, leisure boating, tourism and beach activities. The project will assess the impact that these activities have on the environment and marine life in order to offer further guidance to organisers and water sports enthusiasts. Mike Laflin said: “I’ve worked in the sports industry for 30 years, providing market intelligence and information services and a few years ago I started to measure the impact of sporting events on host cities and nations. I’m excited to support this new research so that we can understand more about how our activities impact the environment and how we can mitigate against any negative effects.” Theresa Laflin said: “We are very excited to be able to support all the wonderful work that the university is doing in the area of marine research, and for increasing our awareness of the detrimental impact we have on our environment.” The PhD project will be supervised by Tamara Galloway, Professor of Ecotoxicology at Exeter, who conducts research into the human health effects of pollutants, particularly micro-plastics in water; and Steve Simpson, Associate Professor in Marine Biology and Global Change at the University of Exeter, who has shown that man-made noise is having a detrimental effect on the marine world. Simpson said: “Noise from offshore construction, shipping and motorboats all change the ocean soundscape, disrupting acoustic communication, robbing animals of fundamental sensory information and causing stress. However, working with industry we have found that by managing when and where noise is made, and developing new technology to reduce the noise, we can mitigate the impacts of noise. Finding solutions to reduce the impacts of sporting activities will further help to protect the marine environment.” Galloway said: “We’ll be looking at all forms of pollution both from everyday leisure activities and major sporting events. Investigating specific events gives us the opportunity to measure environmental quality before and after the event, and to return after a period of time to assess recovery. Such an event could be seen as an ‘acute stressor’. Then we’ll also assess ongoing sporting activities, akin to a ‘chronic stressor’ and will try to compare and contrast different types of impact.”

Read the following passage and choose the best answer (A, B, C, D):
More than a decade ago the UK investigative journalist Nick Davies published Flat Earth News, an exposé of how the mass media had abdicated its responsibility to the truth. Newsroom pressure to publish more stories, faster than their competitors had, Davies argued, led to journalists becoming mere “churnalists”. Shocking as Davies’ revelations seemed in 2008, they seem pretty tame by today’s standards, writes Ben Lorica, Chief Data Scientist at O’Reilly. We now live in a post-truth world of Fake News and “alternative facts”; where activists don’t just seek to manipulate the news agenda with PR but now use advanced technology to fake images and footage. A particularly troubling aspect of these ‘”deepfake” videos is their use of artificial intelligence to fabricate people saying or doing things with almost undetectable accuracy. The result is that publishers risk running completely erroneous stories – as inaccurate as stating that the world is flat – with little or any ability to check their source material and confirm whether it is genuine. The rise of unchecked fakery has serious implications for our liberal democracy and our ability to understand what’s truly going on in the world. The technology to manipulate imagery has come a long way since Stalin had people airbrushed out of history. Creating convincing yet fake digital content no longer requires advanced skills or a well-resourced (mis)information bureau. Anyone with a degree of technical proficiency can create content that will fool even the experts. Take the faked footage of Nancy Pelosi earlier this year, which was doctored to make her look incoherent and was viewed two and a half million times before Facebook took it down. This story shows how social media is giving new life to the old aphorism that “a lie can go halfway around the world before the truth has a chance to put its boots on”. The propagation of lies and misinformation is immeasurably enhanced by platforms like Twitter and Facebook that enable virality. What’s more, the incentives for creating fake content now favour malicious actors, with clear economic and political advantages for disseminating false footage. Put simply, the more shocking or extreme the content, the more people will share it and the longer they will stay on the platform. Meanwhile, counterfeiters can manipulate the very tools being developed to detect and mitigate deepfak content, just as the security industry inadvertently supplies software that can be misused for cybercrime.
