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.

(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.

Human beings are plagued by all kinds of diseases and millions of people die from them. Many of these diseases such as diabetes, polio, whooping cough and diphtheria can be fatal and in the past, people used to die from them. However, with modern technology and a lot of research, scientists and doctors have come up with various ways to cure these diseases, and consequently, many lives are saved. In doing the medical research, doctors have come face to face with many problems. One such problem is the opposition that comes from animal activists. They are against the inhuman treatment of animals. They argue that in conducting their medical research, doctors put animals through a very painful process and this should be stopped. According to the fiercest animal activists, nothing justifies the use of animals in medical experiments, even if lives might be saved. To get their message across, animal activists are even willing to resort to the use of violence. Many animal protection groups, like the Animal Liberation Front (ALF), have broken into laboratories illegally to ‘rescue’ animals. They take away whatever animals they can find and free them. These people also make their case by threatening the researchers. They vandalize medical equipment, and in the most serious cases, they even . In stealing the animals, the activists are actually hindering the progress of medicine. In many cases, the animals were part of research for the cure for various diseases and visual defects in babies. Cures for problems that people face, therefore, come slower and in the waiting period, more people die. Researchers have come up with many cures in the process of working with animals and on animals. Organ transplants are so common today, but we forget that they became only  possible after they were tested on animals. Doctors were able to come up with a cure for river blindness, a disease that affects millions of people in South America and Africa. These are only a few examples, and there are many more. In spite of what animal activists think, most researchers do not treat animals cruelly. In fact, mistreated animals which are in agony will affect the quality of research so that results obtained are not really reliable. Thus, researchers do try to treat animals as well as possible. In the long run, animal activists can cause serious damage to the future of medicine. With their persistent campaigning, much of the public supports their cause. People with AIDS or cancer need doctors to do research to save their lives, and often it is a case where animal research is crucial before any cure can be found

Read the following passage and choose the best answer (A, B, C, D):
When it comes to cooking, boomers cook one, Generation X cooks another way and the beat generation does things that must be recorded now, because once they have passed out of fashion, they will never be discovered again. They have weird skills, derived from scarcity in their early years. They keep their spices in brown glass because they last longer. For practical purposes, this means everything is in an old Calpol bottle with “sumac” scrawled over it. Some of them are, and will fish an empty packet of sugar out of the bin, shake a quarter-teaspoon of sugar from it and put it back. They can often make a cake by eye, without weighing anything, which I find incredible, and they know what to do with leaf gelatine, which is great until it isn’t. My mother once made avocado in jelly and then said: “I don’t know, the proportions may have been slightly off.” I said, recklessly: “Don’t worry – I’m sure I’ll choke it down,” but when it came to it, my cutlery bounced off it, like a prank played on a very hungry person in a cartoon. The beat generation canon is Meat at Any Price and Fish at Any and anything to do with mince. The descent of mince from a sacred food to a bolognese-only staple is one of the great mysteries of progress, because it is delicious even when you don’t shove a load of tomato in it. But you can’t just shove cheap meat in a pan and watch while it sweats out watery grey juice. This seems to be something that only wartime generations understand. Hip parents in the 70s, or regular parents in the 80s, or quite trad parents in the 90s had a horror of overcooked carrots and waterlogged cabbage. The very smell of cooked vegetables evoked for them every bad memory of British cuisine, before anchovies and Italians and radicchio arrived, when all dinner was a school dinner. So they would all just tease their vegetables with a hint of boiling water, before turning them out, still basically a salad, only a bit warmer. Then you, their offspring, would leave home, and accidentally encounter a vegetable that had been cooked, and realise how delicious it was and now you probably overcook your vegetables a bit, and your children will go the other way.

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:
The biological community changes again as one moves from the city to the suburbs. Around all cities is a biome called the "suburban forest". The trees of this forest are species that are favored by man, and most of them have been deliberately planted. Mammals such as rabbits, skunks, and opossums have moved in from the surrounding countryside. Raccoons have become experts at opening garbage cans, and in some places even deer wander suburban thoroughfares. Several species of squirrel get along nicely in suburbia, but usually only one species is predominant in any given suburb -fox squirrels in one place, red squirrels in another, gray squirrels in a third - for reasons that are little understood. The diversity of birds in the suburbs is great, and in the South, lizards thrive in gardens and even houses. Of course, insects are always present. There is an odd biological sameness in these suburban communities. True, the palms of Los Angeles are missing from the suburbs of Boston, and there are species of insects in Miami not found in Seattle. But over wide stretches of the United States, ecological conditions in suburban biomes vary much less than do those of natural biome. And unlike the natural biomes, the urban and suburban communities exist in spite of, not because of, the climate.

Read the following passage and choose the best answer (A, B, C, D):
The human desire for companionship may feel boundless, but research suggests that  our social capital is finite. Social scientists have used a number of ingenious approaches to gauge the size of people’s social networks; these have returned estimates ranging from about 250 to about 5,500 people. An undergraduate thesis from MIT focusing exclusively on Franklin D. Roosevelt, a friendly guy with an especially social job, suggested that he might have had as many as 22,500 acquaintances. Looking more specifically at friendship, a study using the exchange of Christmas cards as a proxy for closeness put the average person’s friend group at about 121 people.  However vast our networks may be, our inner circle tends to be much smaller. The average American trusts only 10 to 20 people. Moreover, that number may be shrinking: From 1985 to 2004, the average number of confidants that people reported having decreased from three to two. This is both sad and consequential, because whoever has strong social relationships tends to live longer than those who don’t. So what should you do if your social life is lacking? Just follow the research. To begin with, don’t dismiss the humble acquaintance. Even interacting with people with whom one has weak social ties has a meaningful influence on well-being. Beyond that, building deeper friendships may be largely a matter of putting in time. A recent study out of the University of Kansas found that it takes about 50 hours of socializing to go from acquaintance to casual friend, an additional 40 hours to become a “real” friend, and a total of 200 hours to become a close friend. If that sounds like too much effort, reviving dormant social ties can be especially rewarding. Reconnected friends can quickly recapture much of the trust they previously built, while offering each other a dash of novelty drawn from whatever they’ve been up to in the meantime. And if all else fails, you could start randomly confiding in people you don’t know that well in hopes of letting the tail wag the relational dog. The academic literature is clear: Longing for closeness and connection is pervasive. Which suggests that most of us are stumbling through the world pining for companionship that could be easily provided by the lonesome stumblers all around us.
6. The word “dormant” in paragraph 4 is closest in meaning to _______

Read the following passage and choose the best answer (A, B, C, D):
Air pollution is the most prominent and dangerous form of pollution. It occurs dues to many reasons. Excessive burning of fuel which is a necessity of our daily lives for cooking, driving and other industrial activities releases a huge amount of chemical substances in the air every day; as a result, these pollute the air. Smoke from chimneys, factories, vehicles or burning of wood basically occurs due to coal burning. This releases sulphur dioxide into the air making it toxic. The effects of air pollution are evident too. Release of sulphur dioxide and hazardous gases into the air causes global warming and acid rain which in turn have increased temperatures, erratic rains and droughts worldwide making it tough for animals to survive. We breathe in every polluted particle from the air, the result is an increase in asthma and cancer in the lungs. Another effect of air pollution is ozone layer depletion. Ozone layer is the thin shield high up in the sky that prevents ultra violet rays from reaching the Earth. As a result of human activities, chemicals, such as chlorofluorocarbons (CFCs) which play a key role, were released into the atmosphere which contributed to the destruction of ozone layer. Water pollution has taken toll of all the surviving species of the earth. Almost 60% of the species live in water bodies. It occurs due to several factors; the industrial wastes dumped into the rivers and other water bodies cause an imbalance in the water leading to its severe contamination and death of aquatic species. If you suspect that nearby water sources have been contaminated by a corporation then it might be a good idea to hire an expert to see you options. Moreover, spraying insecticides, pesticides like DDT on plants also pollutes the ground water system and oil spills in the oceans have caused irreparable damage to the water bodies. Eutrophication is another big source; it occurs due to daily activities like washing clothes or utensils near lakes, ponds or rivers; this forces detergents to go into water which blocks sunlight from penetrating, thus reducing oxygen and making it inhabitable. Water pollution not only harms the aquatic beings but it also contaminates the entire food chain by severely affecting humans dependents on these. Waterborne disease like cholera, diarrhea have also increased in all places. Another type of pollution common in the countryside is soil pollution. Soil pollution occurs due to the incorporation of unwanted chemicals in the soil due to human activities. Insecticides and pesticides absorb the nitrogen compounds in the soil making it unfit for plants to derive nutrition. Release of industrial waste, mining and deforestation also damages the soil. Since plants can’t grow properly, they can’t hold the soil and this leads to soil erosion.

Read the following passage and choose the best answer (A, B, C, D):
Zoos used to be primarily a place for people to see wild animals they had never seen.  Now, however, zoos serve a new purpose – to be captive-breeding programs for endangered animals. There are less than a hundred Sumatran rhinos worldwide, and three were born in Cincinnati Zoo. When old enough, one of the males was sent to Way Kamabas National Park in Sumatra and this helped to start the process of re-populating his species in the wild and saving it from the extinction.  Other zoos have started captive-breeding programs as well. Zoos have saved the Arabian onyx, the black-footed ferret, the red wolf, the Guam rail, and the California condor. But the cost of the programs for saving the threatened animals is not cheap. The condor program alone costs up to $2 million a year. While it is mostly large-city zoos involved in captive breeding, smaller zoos do their part. The Miller Park Zoo in Bloomington, Illinois, is working on breeding the endangered, and small. Mount Graham red squirrel.  Zoos have always been involved in animal conservation to some degree, but the question of which animals to save is a big one. Endangered animals may not be the most exciting to see in a zoo, and to di conservation work the zoos must survive financially. Space is a problem as well. A zoo might be able to save a small number of large animals or a large number of small ones. Currently, the most threatened group of animals is amphibians. Zoos realize that visitors may not want to see frogs, salamanders, or other small animals and may only pay to see rhinos, lions, and tigers. Some scientists believe zoos should be less tourist attractions and more conservation sanctuaries. Thus, although zoos continue to do good work, they still confront tricky questions. There are a limited number of animals that can be cared for in zoos, and that means many species on the edge of extinction may not survive. The Sumatran orangutan and a thousand other threatened species have not made it into a captive-breeding program, but the species will continue to exist. How? In the Frozen Zoo. Cells from these animals are stored in the San Diego Zoo Institute for Conservation Research in liquid nitrogen. Only one animal in the Frozen Zoo is presently extinct, but many others are at dire risk. In the Frozen Zoo, however, the cells of animals will be preserved for study through their genetic material.

Read the following passage and choose the best answer (A, B, C, D):
Kids can be creatures of habit. Much like how they can watch the same movie over and over, some kids will stick to one author or genre of book that they’ve fallen in love with. But does it matter if they’re always reading the same type of book? After all, isn’t their love of reading in itself enough? Reading builds their imagination, develops their critical thinking skills, and improves their communication skills, amongst many other benefits. Well, while a love of reading of any sort is to be nurtured, when a child only reads the same author or type of book, their growth and the benefits they gain may not be as broad if they were to explore more types of books. Coaxing them to open up to reading other genres can be a big advantage for them in the long term. They will get exposed to different types of characters and lifestyles when they read a wider range of writing. For example, their favourite fantasy novels may spark their imagination, but true tales of life halfway around the world can trigger interest in traveling and foster understanding of other cultures. It helps them develop a broad perspective on the world around them. Their vocabulary will benefit, too, if they read a wide selection of books. Think of the words and the sentence structure used in a vampire book and how they will differ significantly from those in a suspense novel. They will have to sound out words, and it’ll be helpful to have a dictionary handy. With each new word encountered in the broad range of reading materials they’re consuming, their vocabulary grows. Reading a variety of books will also help your child grow their love of reading and it’ll fuel their motivation to read more and more. They once only adored one author, who has  a limited number of books written, discovering new authors or types of books expands their choice of reading material; they’ll never run out of books to add to their reading list! Consider, too, the value of specific types of books for very young readers. Ones that teach the alphabet help them learn that letters come together to form the words in books. Poetry with rhyming words will help develop a child’s phonemic awareness, which is the ability to hear, identify and manipulate individual sounds in spoken words. Folktales and nursery rhymes are beloved and cherished. Surely there are ones that bring you right back to your childhood, and they tend to be shared from one generation to the next - your child’s favourite will likely be ones they teach their children when they grow up and have kids of their own!

Read the following passage and choose the best answer (A, B, C, D):
There are a number of initiatives, some already introduced and some in the pipeline,  that are specifically designed to ensure that the economic value of nature is recognised. One example is reduced emissions from deforestation and forest degradation, under  which forest owners are paid not to cut down trees. A number of governments across the world have committed hundreds of millions of dollars to these projects. Another is habitat banking, the market for which currently stands at around $3bn in the US, where companies that degrade natural areas are forced to restore nature elsewhere. Trade in forest conservation obligations in Brazil and ground-water salinity credits in Australia have also proved successful. Alongside these schemes and those like them, there are various compensation arrangements that make those causing environmental damage pay for it, just like carbon credits that currently exist. Exemptions from these various taxes, charges and fees, as well as subsidies, are also used to encourage environmentally responsible behaviour.  There is also growing pressure for companies to begin incorporating the costs of the damage that they do to the Earth’s natural resources into their profit and loss accounts. Only by incorporating these costs into their accounts, many argue, will companies be forced to reduce their impact on the natural world. "Directors’ bonuses don’t have to be included in company accounts from a pure profit and loss point of view, but they are. Environmental externalities should be the same," says Pavan Sukhdev, a career banker and team leader of the United Nations’ The Economics of Ecosystems and Biodiversity study.  “This is not a straightforward process and needs standard methodologies accepted by everyone, but it could be achieved within 10 years.” The next step would be to incorporate environmental assets into national accounts.

Read the passage carefully and choose the correct answer.

Communication in general is process of sending and receiving messages that enables humans to share knowledge, attitudes, and skills. Although we usually identify communication with speech, communication is composed of two dimensions - verbal and nonverbal. Nonverbal communication has been defined as communication without words. It includes apparent behaviors such as facial expressions, eyes, touching, tone of voice, as well as less obvious messages such as dress, posture and spatial distance between two or more people. Activity or inactivity, words or silence all have message value: they influence others and these others, in turn, respond to these communications and thus they are communicating. Commonly, nonverbal communication is learned shortly after birth and practiced and refined throughout a person's lifetime. Children first learn nonverbal expressions by watching and imitating, much as they learn verbal skills. Young children know far more than they can verbalize and are generally more adept at reading nonverbal cues than adults are because of their limited verbal skills and their recent reliance on the nonverbal to communicate. As children develop verbal skills, nonverbal channels of communication do not cease to exist although become entwined in the total communication process.

Which is not included in nonverbal communication?

Egypt’s 100 millionth citizen was born last week, undoubtedly a happy occasion for one family, but a moment filled with foreboding for a country struggling to contain a population explosion. In the past year the government has scrambled to stem the birth rate with a new program called “Two is Enough.” It is establishing family planning clinics throughout the country, where Egyptians can purchase heavily subsidized contraceptives. But many doctors and activists fear that this is too little, and comes too late to reverse the uptick in population growth. Doctors complain that the new “Two is Enough” program lacks in a clear strategy to bring down birthrates. The financial resources deployed thus far have been a fraction of previous efforts; some family-planning clinics have reportedly run out of contraceptives. While clinics funded by the campaign to provide some reproductive health education, sexual education remains taboo in Egyptian schools. There is also a lack of adequate services for the poor and pensioners. Many Egyptians opt to have more children in the hope they will look after them as they age, a phenomenon common in countries with high levels of poverty and inadequate safety nets. While over 30 million Egyptians live in poverty, only 9.4 million receive means-tested cash transfers from the government’s welfare programs. Economic reforms undertaken as part of a recently completed International Monetary Fund program have cut subsidies in a number of areas, contributing a spike in inflation that at one point exceeded 30%. For newborns like the 100-millionth Egyptian, the outlook is grim. A burgeoning population exacerbates many problems. Despite Egypt’s limited supply - it depends almost exclusively on the Nile - there has been a systemic failure to adequately address water waste. From wasteful megaprojects draining the Nile to literally dumping waste in the river, Egyptian officials have consistently failed to prudently protect what is perhaps the country’s most vital natural resource. In 2018, Egypt temporarily reduced the farming of rice, a water intensive crop - only to expand cultivation the following year. The New Administrative Capital that Sisi has set out to erect is projected to need 650,000 cubic meters of water per day when finished. Failure to quickly and dramatically improve water management practices in Egypt could be disastrous, and the risk is the greater for the country’s rapid population growth
