Climate change, also called global warming, refers to the rise in average surface temperatures on Earth. An overwhelming scientific consensus maintains that climate change is due primarily to the human use of fossil fuels, which (1) __________ carbon dioxide and other greenhouse gases into the air. The gases trap heat within the atmosphere, which can have a range of effects on ecosystems, (2) __________ rising sea levels, severe weather events, and droughts that render landscapes more susceptible to wildfires. While consensus among nearly all scientists, scientific organizations, and governments is (3)__________ climate change is happening and is caused by human activity, a small minority of voices questions the validity of such assertions and prefers to cast doubt on the preponderance of evidence. Climate change deniers often claim that recent changes (4) __________ to human activity can be seen as part of the natural variations in Earth’s climate and temperature, and that it is difficult or impossible to establish a direct connection between climate change and any single weather event, such as a hurricane.

Environmentalists often fear that tourists will trample all over sensitive natural resource areas, but tourism may bring the needed and only economic incentives to help drive conservation, said Bynum Boley. Ecotourism and natural resource conservation already have a mutually beneficial relationship that is ideal for creating a sustainable partnership. “Ecotourism destinations benefit in the form of enhanced tourism competitiveness from the protection of quality natural resources,” he said. "Meanwhile, the conservation of these natural resources is increasingly valued since these pristine natural resources are the foundation of the ecotourism industry and the driver of all economic benefits associated with ecotourism." Tourism is a $7.6 trillion global industry, provides 277 million jobs and is a primary income source for 20 of the world’s 48 least-developed countries. It also subsidizes environmental protection and helps protect, conserve and value cultural resources that might otherwise be undervalued by the host community, Boley said. In the newpaper, Boley and coauthor Gary Green said that despite past tension between the tourism industry and environmentalists, the two should team up as allies to fight off increasing conversion of land away from its natural state. Ecotourists not only provide a boost to the economy in such places, they can also motivate landowners into keeping the environment in its natural state instead of converting it into something unsustainable. They could also influence the public perception of conservation, Boley explained, which does not often favor environmental protection. “The public has become increasing less prone to respond to environmental messages,” he said. “Economic messages are needed in order to attract the public’s interest.” Too often, Boley and Green said, unique natural resource areas are converted into urban, suburban and agricultural developments without considering their ecotourism potential. In addition to the lost ecotourism revenue, there are a host of negative environmental consequences such as biodiversity loss, water and food shortages and the land being unable to mitigate the effects of climate change. These areas are not valued for their unique attributes or the valuable natural resources they provide, Green said, “so we lose them.” Tourists have historically been seen as having a negative impact on the environment. Critics complain that they violate fragile and threatened natural environments while contributing to greenhouse gases from the increased number of flights to these exotic and often remote locales. While these criticisms are justified, Boley and Green said responsible programs promote education of ecological conservation and environmental sustainability, fostering a greater understanding and appreciation of these exotic areas

In 1959 Xerox created the first plain paper copy machine. It was one of the most  successful products ever. The company name Xerox grew into a verb that means “to copy,” as in “Bob, can you Xerox this for me?” Around 50 years later, the same thing happened to Google. Their company name grew into a verb that means “to do an internet search.” Now everyone and their grandma knows what it means to Google it.  Unlike Xerox, Google wasn’t the first company to invent their product, not by a long shot. Lycos released their search engine in 1993. Yahoo! came out in 1994. AltaVista began serving results in 1995. Google did not come out until years later, in 1998. Though a few years difference may not seem like much, this is a major head start in the fast moving world of tech. So how did Google do it? How did they overtake their competitors who had such huge leads in time and money? Maybe one good idea made all the difference.  There are millions and millions of sites on the internet. How does a search engine know which ones are relevant to your search? This is a question that great minds have been working on for decades. To understand how Google changed the game, you need to know how search engines worked in 1998. Back then most websites looked at the words in your query. They counted how many times those words appeared on each page. Then they might return pages where the words in your query appeared the most. This system did not work well and people often had to click through pages and pages of results to find what they wanted.  Google was the first search engine that began considering links. Links are those blue underlined words that take you to other pages when you click on them. Larry Page, cofounder of Google, believed that meaningful data could be drawn from how those links connect. Page figured that websites with many links pointing at them were more important than those that had few. He was right. Google’s search results were much better than their rivals. They would soon become the world’s most used search engine.  It wasn’t just the great search results that led to Google becoming so wellliked. It also had to do with the way that they presented their product. Most of the other search engines were cluttered. Their home pages were filled with everything from news stories to stock quotes. But Google’s homepage was, and still is, clean. There’s nothing on it but the logo, the search box, and a few links. It almost appears empty. In fact, when they were first testing it, users would wait at the home page and not do anything. When asked why, they said that they were, “waiting for the rest of the page to load.” People couldn’t imagine such a clean and open page as being complete. But the fresh design grew on people once they got used to it.

Read the following passage and choose the best answer (A, B, C, D)
Gender inequality remains an everyday reality for the world’s women and girls. It can begin right at the moment of birth and continue throughout the course of a woman’s life. Despite critical advances over the course of recent history, women in all countries and across all socioeconomic levels in society can face various forms of unfair treatment, including discrimination, harassment, domestic violence and sexual abuse. Other forms of abuse that are particularly prevalent in certain countries or cultural contexts include forced marriage, honor killings, deprivation of education, denial of land and property rights, and lack of access to work and to health care. Women may experience human rights abuses at different points in their working lives, including during recruitment, hiring, promotion and termination processes, as well as in daily interactions with colleagues and supervisors. Outside of the workplace, women are often particularly vulnerable to the social and environmental impacts of business activities. For example, in many developing countries, women and girls are primarily responsible for fetching and hauling water. When company operations contaminate local sources, it is they  who carry the burden of walking, often for hours, to the nearest substitute, which can prevent them from working or going to school. According to the UN Entity for Gender Equality and the Empowerment of Women, gender “refers to the social attributes and opportunities associated with being male and female and the relationships between women and men and girls and boys, as well as the relations between women and those between men. These attributes, opportunities and relationships are socially constructed and are learned through socialization processes.” Furthermore, gender equality “refers to the equal rights, responsibilities and opportunities of women and men and girls and boys. Equality does not mean that women and men will become the same but that women’s and men’s rights, responsibilities and opportunities will not depend on whether they are born male or female.” Women and girls comprise half of the planet’s population; their empowerment is essential in expanding economic growth and promoting social development in a sustainable way. Evidence from around the world shows that gender equality advancements have a ripple effect on all areas of sustainable development, from reducing poverty, hunger and even carbon emissions to enhancing the health, well-being and education of entire families, communities and countries. In fact, “Equality between women and men is seen both as a human rights issue and as a precondition for, and indicator of, sustainable people-centered development.”

Read the following passage and choose the best answer (A, B, C, D):
The fresh data released by the Centre for Monitoring Indian Economy (CMIE)  showed that unemployment rate in the month of October jumped to 8.5 per cent, which is the highest in over three years. A new academic research paper released by the Centre of Sustainable Employment also concluded that there has been a marked decline in total employment in India between 2011-12 and 2017-18, reported The Indian Express.  The research paper by Santosh Mehrotra and Jaiati K Parida stated as, "However, due to sharp increases in enrollment at every level of education over the noughties, it was expected that post -2012 total employment would increase, particularly in the non-farm sectors. But unfortunately, total employment during 2011-12 and 2017-18 declined by 9 million. The research further states that this happened for the first time in India’s history.  It is really ironical noting that Coimbatore Municipal Corporation posted a vacancy for 549 sanitary workers. What followed was that 7000 highly qualified applicants even some of them with engineering and graduate degrees applied for the job. The Corporation witnessed the overwhelming turnout of 7000 candidates. Similarly, few month back, Chennai witnessed an unusual event when around 4600 of youth sent their application for 14 posts like sweepers and sanitary workers. The applicants had professional qualification like B.Tech, M.Tech, Master of Business Administration.  Though the government constantly has been refuting the grim of job data but the facts and figures can’t be avoided any more. Therefore, now the government should take an initiative to overcome the high prevalence of unemployment and figure out the derivers of the job crisis. In this regard, it is worth to mention a book titled ‘Job crisis in India’ written by business journalist Raghavan Jagnnathan. The author in his book pointed out factors and reasons behind this decline of employment. He attributed that the absence of skills required in the highly technical nature of jobs is big factor. Another aspect of this is that in the majority of cases the skills or training acquired by the youths do not match or suit the core demand of the job. So at first the government must step up for reformation, innovation and renovation of the standard of the education in universities and colleges. 
4. What does the phrase “the noughties” in paragraph 2 most likely mean?

A pilot cannot fly by sight alone. In many conditions, such as flying at night and landing in dense fog, a pilot must use radar, an alternative way of navigating. Since human eyes are not very good at determining speeds of approaching objects, radar can show a pilot how fast nearby planes are moving. The basic principle of radar is exemplified by what happens when one shouts in a cave. The echo of the sounds against the walls helps a person determine the size of the cave. With radar, however, the waves are radio waves instead of sound waves. Radio waves travel at the speed of light, about 300,000 kilometres in one second. A radar set sends out a short burst of radio waves. Then it receives the echoes produced when the waves bounce off objects. By determining the tune it takes for the echoes to return to the radar set, a trained technician can determine the distance between the radar set and other objects. The word "radar" in fact gets its name from the term "radio detection and ranging". "Ranging" is the term for detection of the distance between an object and the radar set. Besides being of critical importance to pilots radar is essential for air traffic control tracking ships at sea, and for tracking weather Systems and storms.

What might be inferred about radar?

Of the six outer planets, Mars, commonly called the red planet, is the closest to Earth. Mars, 4,200 miles in diameter and 55 percent of the size of Earth, is 34,600,000 miles from Earth, and 141,000,000 miles from the Sun. It takes this planet, along with its two moons, Phobos and Deimos, 1.88 years to circle the Sun, compared to 365 days for the Earth.

For many years, Mars had been thought of as the planet with the man-made canals, supposedly discovered by an Italian astronomer, Schiaparelli, in 1877. With the United States spacecraft Viking I's landing on Mars in 1976, the man-made canal theory was proven to be only a myth.

Viking I, after landing on the soil of Mars, performed many scientific experiments and took numerous pictures. The pictures showed that the red color of the planet is due to the reddish, rocky Martian soil. No biological life was found, though it had been speculated by many scientists. The Viking also monitored many weather changes including violent dust storms. Some water vapor, polar ice, and permafrost (frost below the surface) were found, indicating that at one time there were significant quantities of water on this distant planet. Evidence collected by the spacecraft shows some present volcanic action, though the volcanoes are believed to be dormant, if not extinct.

Birds are even more disrupted by their noisy neighbours than had been thought  previously, researchers have found. And human activities could be preventing birds from reproducing and even developing normal social behaviour and keeping the peace.  A study by Queen’s University Belfast found that when European robins were subjected to human produced noises their behaviour changed. Background noise appeared to mask the communication of crucial information between birds. While aggressive communication is common and birds respond to it, interference through noise can lead to the birds mistaking the signals.  Birds can end up in situations all too familiar to humans. “The birds receive incomplete information on their opponent’s intent and do not appropriately adjust their response,” explained Arnott. “Where song is disguised by background noise, in some cases the male ends up fighting more vigorously than he should, but at other times gives in too easily.”Arnott said the purpose of birdsong was twofold – to attract mates and defend territory. Birds already face an array of human-made dangers, from pesticides and intensive farming to shooting and poisoning. But noise had often been overlooked, the paper in Biology Letters found. A spokesperson for the RSPB said: “Everyone is becoming increasingly concerned that nature is in crisis in the UK, with one in 10 of our wildlife species at threat of extinction. Many of our birds’ populations are already facing a serious crisis as a result of habitat loss, climate change and other human activities. This report is a good reminder that the way we live and our lifestyle has an impact on our natural world, and that we need to protect our natural world if we want to let nature sing.”  For birds, the extra burden of noise pollution adds to extraordinary decline in species, including among once common birds, in recent decades due to such activities as agricultural practice and pesticide use. In the experiment the team used playbacks of robin song to stimulate responses from birds who were territory holders. Simple or complex songs were used in either the presence or absence of noise. The researchers found that song complexity  was used as a signal of aggressive intent; birds demonstrated higher aggressive intent towards complex rather than simple song. This process was disrupted by the presence of added noise.

Mark the letter A, B, C, or D on your answer sheet to indicate the undelined part that needs correction in each of the following questions:
(Line 1) Horace Pippin, as an African-American soldier during World War I, was wounded in his right arm. He discovered, however, that by keeping his right wrist steady with his left hand, he could paint and draw. Pippin was not trained, but his artistic sensitivity and intuitive feel for two- dimensional design and the arrangement of colour and patterns made him one of the finest Primitive artists America has produced.
(Line 6) Pippin did a series of paintings on the abolitionist John Brown and one on his war experiences, but he shied away from social issues for the most part and achieved his greatest success with scenes of the people and places of his hometown of West Chester, Pennsylvania. His Domino Players, featuring four women gathered around a wooden table in a simple kitchen setting, is an excellent example of his rural domestic scenes.

Read the following passage and choose the best answer (A, B, C, D):
Even though it’s sometimes hard for parents to think about letting go of their child, the best relationships are the ones that teens come back to, as adults, recognizing how their parents have helped them into adulthood by not clinging or pushing them away too soon. We recommend that parents look for opportunities to teach independence, starting in childhood. Encourage your teen to be responsible for his or her own time. “How much time do you need for homework?” “How long to do you need to unwind after school?” If the answers to these questions are “None” and “Until midnight”, then your teen needs some help making a schedule. Many teens can come up with a reasonable time for getting things done, with some practice and initial limits from you. You may want to let her try out her schedule through, say, one grading period. If grades go down, the schedule needs work and maybe more supervision from you. Not knowing basic financial skills can be one the first things to trip up a newly independent young adult. Look for chances to teach basic money skills. Some parents give their teen a set amount of money and let her plan the weekly grocery shopping or family vacation. Have her help you pay utility bills and budget for expenses. Explain carefully about credit cards and limit access to credit. Teens are impulsive, and easily get stuck in the trap of  charging more than they can pay off. An after-school job is a great opportunity for your teen to start practicing. More than anything else, teens learn from making mistakes. As a parent, your job is to try to make sure that the mistakes your teen makes aren’t life-threatening, like getting into the car with a drunk driver. Most mistakes, though, will not fall into that category. No one is perfect, especially parents. It’s important that teen see that you do not expect perfection from him or from yourself, and that you can admit your mistakes when you make them. Letting your teen make mistakes, and letting him suffer the consequences of a mistake, can be hard to do. But when you give your teen permission to make mistakes, and let him know you love him anyway, you tell him that you believe in his ability to take a fall, get up and learn from it

Read the following passage and choose the best answer (A, B, C, D):
We live in a world of tired, sleep deprived people. In his book Counting Sheep, Paul Martin - a behavioral biologist - describes a society which is just too busy to sleep and which does not give sleeping the importance it deserves. Modern society has invented reasons not to sleep. We are now a 24/7 society where shops and services must be available all hours. We spend longer hours at work than we used to, and more time getting to work. Mobile phones and email allow us to stay in touch round the clock and late-night TV and the Internet tempt us away from our beds. When we need more time for work or pleasure, the easy solution is to sleep less. The average adult sleeps only 6.2 hours a night during the week, whereas research shows that most people need eight or even eight and a half hours’ sleep to feel at their best. Nowadays, many people have got used to sleeping less than they need and they live in an almost permanent state of “sleep debt”.  Until the invention of the electric light in 1879 our daily cycle of sleep used to depend on the hours of daylight. People would get up with the sun and go to bed at nightfall. But nowadays our hours of sleep are mainly determined by our working hours (or our social life) and most people are woken up artificially by an alarm clock. During the day caffeine, the world’s most popular drug, helps to keep us awake. 75% of the world’s population habitually consume caffeine, which up to a point masks the symptoms of sleep deprivation. What does a chronic lack of sleep do to us? As well as making us irritable and unhappy as humans, it also reduces our motivation and ability to work. This has serious implications for society in general. Doctors, for example, are often chronically sleep deprived, especially when they are on “night call”, and may get less than three hours’ sleep. Lack of sleep can seriously impair their mood, judgment, and ability to take decisions. Tired engineers, in the early hours of the morning, made a series of mistakes with catastrophic results. On our roads and motorways lack of sleep kills thousands of people every year. Tests show that a tired driver can be just as dangerous as a drunken driver. However, driving when drunk is against the law but driving when exhausted isn’t. As Paul Martin says, it is very ironic that we admire people who function on very little sleep instead of criticizing them for being irresponsible. Our world would be a much safer, happier place if everyone, whatever their job, slept eight hours a night

Read the following passage and choose the best answer (A, B, C, D):
Human’s avarice for ivory has resulted in thousands of unfathomable elephant atrocities and senseless suffering that has pushed the species to the brink of extinction. In 2015, the U.S. and China announced they will work together to enact a near complete ban on the import and export of ivory. As an industry that has largely been driven by China and, if substantiated, these claims could be a ray of light for one of the most endangered animals in the kingdom. However, as the famous saying goes, “for every action, there is an equal and opposite reaction.” With the worldwide attention on elephant ivory, hippo teeth, which can grow up to three-feet-long, have become the next target. Since the United Nations Convention on International Trade in Endangered Species officially imposed a ban on ivory trading in 1990, about 30,000 pounds per year of hippo teeth have been exported from Africa. On a recent trip to Kenya, I had the unfortunate displeasure of meeting these facts face-to-face. On the banks of the Mara River, the infamous transient point of the great wildebeest migration, I met a Conservancy Ranger, a local Kenyan, named Ivan. He led me along a narrow path above the riverbed to view pods of hippos. They clumped together in the river, every few minutes lifting their heads above the waterline to welcome my arrival. Despite their label as one of the most dangerous animals in Africa, they were playful to watch. Their tiny ears and eyes would appear from the murky river and then, with a splash, they would disappear. The river is everything to the hippo, Ivan explained, it is their lifeline. The only real time they leave the river is during their nightly ritual of traveling to nearby plains to consume grasses. Contrary to their aggressiveness, they are vegetarians. As we neared the end of our trek, we reached the Mara Bridge, spanning the divide between Kenya and Tanzania. An undeniable stench filled the air. Our gaze fell to the water beneath the structure, and as if to mark the metaphorical significance of the passage, lay a poached hippo. It had been killed the previous night, probably as it grazed unsuspectingly under the cover of darkness. They had found spear punctures in its body, and its teeth were missing. It had somehow, in unthinkable pain, made its way back to the river, its home, to die.

Read the following passage and choose the best answer (A, B, C, D):
Deforestation is the clearing, destroying, or otherwise removal of trees through  deliberate, natural or accidental means. It can occur in any area densely populated by trees and other plant life, but the majority of it is currently happening in the Amazon rainforest. The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people.  Deforestation occurs for a number of reasons, including: farming, mostly cattle due to its quick turn around; and logging for materials and development. It has been happening for thousands of years, arguably since man began converting from hunter/gatherer to agricultural based societies, and required larger, unobstructed tracks of land to accommodate cattle, crops, and housing. It was only after the onset of the modern era that it became an epidemic.  One of the most dangerous and unsettling effects of deforestation is the loss of animal and plant species due to their loss of habitat; not only do we lose those known to us, but also those unknown, potentially an even greater loss. Seventy percent of Earth’s land animals and plants live in forests, and many cannot survive the deforestation that destroys their homes. The trees of the rainforest that provide shelter for some species also provide the canopy that regulates the temperature, a necessity for many others. Its removal through deforestation would allow a more drastic temperature variation from day to night, much like a desert, which could prove fatal for current inhabitants. In addition to the loss of habitat, the lack of trees also allows a greater amount of greenhouse gases to be released into the atmosphere. Presently, the tropical rainforests of South America are responsible for 20% of Earth’s oxygen and they are disappearing at a rate of 4 hectares a decade. If these rates are not stopped and reversed, the consequences will become even more severe.  The trees also help control the level of water in the atmosphere by helping to regulate the water cycle. With fewer trees left, due to deforestation, there is less water in the air to be returned to the soil. In turn, this causes dryer soil and the inability to grow crops, an ironic twist when considered against the fact that 80% of deforestation comes from small-scale agriculture and cattle ranching.  Further effects of deforestation include soil erosion and coastal flooding. In addition to their previously mentioned roles, trees also function to retain water and topsoil, which provides the rich nutrients to sustain additional forest life. Without them, the soil erodes and washes away, causing farmers to move on and perpetuate the cycle. The barren land which is left behind in the wake of these unsustainable agricultural practices is then more susceptible to flooding, specifically in coastal regions. Coastal vegetation lessens the impact of waves and winds associated with a storm surge. Without this vegetation, coastal villages are susceptible to damaging floods.
5. The following are negative effects of deforestation, EXCEPT __________
