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:
Birds have evolved many physical attributes that contribute to their flying ability. Wings are important, but adjustable tails, large hearts and light bones play critical roles.
To fly, birds, like airplanes, move air across their wings. Wings are designed so that air above the wings is forced to move faster than air below the wing. This creates higher pressure under the wings, called lift, which pushes the bird up. Different wing types evolved for different ways of flying. Prolonged flight requires long wings and an ability to soar. Other birds need superior maneuverability. Finches and sparrows
have short, broad wings. Faster birds, like hawks, have built-in spoilers that reduce turbulence while flying. This allows a steeper angle of attack without stalling.
Tails have evolved for specialized use. The tail acts like a rudder helping birds steer. Birds brake by spreading out their tails as they land. This adaptation allows them to make sudden, controlled stops-an essential skill, since most birds need to land on individual branches or on prey.
Flight takes muscle strength. If body builders has wings, they still could not flap hard enough to leave the ground. Birds have large, specialized hearts that beat much faster than the human heart and
provide the necessary oxygen to the muscles. The breast muscle accounts for 15 percent of the bird’s body weight. On pigeons, it accounts for a third of their total body weight.
Birds carry no excess baggage; they have hollow feathers and hollow bones with struts inside to maintain strength, like cross beams in a bridge. Birds fly to find prey, escape predators, and attract mates- in other words, to survive.

According to the passage, what benefit comes from having built-in spoilers?

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:
Buying a house is the single largest financial investment an individual makes. Yet, in India this act is fraught with risk and individuals depend on weak laws for justice. Occasionally, deviant promoters are called to account as was the case in the detention of Unitech’s promoters. This incident shows up the fallout of an absence of proper regulation to cover contracts between buyers and real estate promoters. A real estate bill, which is presently pending in Rajya Sabha, seeks to fill this gap. It has been debated for over two years and should be passed by Parliament in the budget session.
India is in the midst of rapid urbanization and urban population is expected to more than double to about 900 million over the next three decades. Unfortunately, even the current population does not have adequate housing. A government estimate in 2012 put the shortage at nearly 19 million units. If this shortage is to be alleviated quickly, India’s messy real estate sector needs reforms.
The real estate bill seeks to set standards for contracts between buyers and sellers. Transparency, a rare commodity in real estate, is enforced as promoters have to upload project details on the regulators’ website. Importantly, standard definitions of terms mean that buyers will not feel cheated after taking possession of a house. In order to protect buyers who pay upfront, a part of the money collected for a real estate project is ring-fenced in a separate bank account. Also, given the uncertainty which exists in India on land titles, the real estate bill provides title insurance. This bill has been scrutinized by two parliamentary committees and its passage now brooks no delay.
This bill is an important step in cleaning up the real estate market, but the journey should not end with it. State governments play a significant role in real estate and they are often the source of problems. Some estimates suggest that real estate developers have to seek approvals of as many as 40 central and state departments, which lead to delays and an escalation in the cost of houses. Sensibly, NDA government’s project to provide universal urban housing forces states to institute reforms to access  central funding. Without real estate reforms at the level of states, it will not be possible to meet the ambition of making housing accessible for all urban dwellers.

The word “escalation” in the last paragraph is closest in meaning to .

        Many older cities are having modern makeovers and they are being given a new (1) ______. Sometimes the impetus for this type of change comes from the need to provide new facilities for particular events being held in the city - a sporting event, or something similar. On other occasions the change just seems to take place almost naturally.

      Urbanization degrades the environment, according to conventional wisdom. This view has led many developing countries to limit rural - urban migration and curb urban expansion. But this view is incorrect. There are a number of reasons urbanization can be good for the environment, if managed properly.
      First, urbanization brings higher productivity because of its positive externalities and economies of scale. Asian urban productivity is more than 5.5 times that of rural areas. The same output can be produced using fewer resources with urban agglomeration than without. In this sense, urbanization reduces the ecological footprint. The service sector requires urbanization because it needs a concentration of clients. As services generally pollute less than manufacturing, this aspect of urbanization is also beneficial to the environment.
      Second, for any given population, the high urban density is benign for the environment. The urban economics literature shows that compactness is a key determinant of energy use. High density can make public transport more viable and reduce the length of trips. Urban living encourages walking and cycling rather than driving. Third, environment-friendly infrastructure and public services such as piped water, sanitation, and waste management are much easier and more economical to construct, maintain, and operate in an urban setting. Urbanization allows more people to have access to environment-friendly facilities and services at affordable prices.
     Fourth, urbanization drives innovation, including green technologies. In the long term, environment-friendly equipment, machines, vehicles, and utilities will determine the future of the green economy. Green innovations in Asia's cities will be supported by the region's vast market as the billions of people who will be buying energy-efficient products will create opportunities and incentives for entrepreneurs to invest in developing such products. Finally, the higher standard of living associated with urbanization provides people with better food, education, housing, and health care. Urban growth generates revenues that fund infrastructure projects, reducing congestion and improving public health. Urbanization fosters a pro-environment stance among property owners and the middle class, which is crucial for the introduction and enforcement of environmental laws and regulations.
      Of course, urbanization also comes with costs. Millions of people are migrating to Asian cities and companies are locating there to employ them. Urban sprawl and industrial activities, such as power generation, transportation, construction, garbage and waste disposal, harm the environment. An assessment of the impact of urbanization on the environment must balance its benign and adverse effects.

What does it take to graduate from university with a First?

Mark McArdle, first–class degree holder from the University of Lancaster, tells how he did it.

Don’t spend too much time at the student lounge, do turn up for most lectures and tutorials and do submit all coursework – eventually. That, I was told by a PhD student during freshers’ week, was all I needed to do to get a 2:2. For a 2:1, I’d require a better attendance record and have to work harder, but not at the expense of being cut off from civilization. And for a First I would have to become some sort of social outcast, go to even lecture and tutorial (scribbling notes madly), spend every waking moment immersed in academic books, and be among the last to be thrown out of the university library at 10 pm closing time.

Well, I did not give up my life for study. I didn't attend every lecture and tutorial. I didn’t write down every word spoken in lectures. I didn’t get 80% or more in every essay, project, test or exam. I was usually behind with my reading and occasionally mystified by the syllabus. Sometimes I couldn't be bothered to go to university and stayed at home instead. But I always knew where I was what I had to do and what not to bother with. And I always worked hard on the things that counted: assignments and exams.

Getting a degree is about learning, but it isn’t just about learning biology, history, English or whatever. It’s about understanding what you need to succeed − what, in fact, the university wants from you and what you will get in return. You have to have a feel for the education market and really sell your inspirations. What does the lecturer want? What is the essay marker searching for? Some students try to offer something not wanted. Others want to give very little − they steal the thoughts of others and submit them as their own. But they all want to be rewarded. Exchange, but don’t steal, and you’ll get a degree.

I could guarantee every book on my reading list was out on long loan from the university library within five seconds of the list being issued. This was worrying at first, but I quickly learned that it was impossible to read all of the books on an average reading list anyway. I sought shortcuts. Collections of selected readings or journal articles were excellent sources that often saved me the bother of reading the original texts. References in books dragged me all over the place but with all the courses I had to do, there wasn't enough time to be dragged too far. I would flick through the book, read the introduction, note any summaries, look at diagrams, skim the index, and read any conclusions. I plucked out what was needed and made my escape.

I revised by discarding subject areas I could not face revising, reading, compiling notes, and then condensing them onto one or two sheets of A4 for each subject area. Leading up to the exam, I would

concentrate on just the condensed notes and rely on my memory to drag out the detail behind them when the time came. I didn’t practice writing exam questions, although it was recommended. I prefer to be spontaneous and open–minded. I don't want pre–formed conclusions filling my mind.

And nor should you; there is no secret to getting a First – this is just an account of how I got my First. Be a happy student by striking the right balance between working and enjoying yourself. Take what you do seriously and do your best. And, no matter what you do don’t forget to appreciate every day of your university studies: it is one of the greatest periods of your life.

What is the main purpose of the passage?

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:
Pollution emitted in industrial areas represents a threat to human health and the surrounding natural resources. We have a tendency to  believe that the  production processes are  the only source of environmental damage, and often forget about the possible long-term effects of harmful production practices. We may think that the closure of these huge industrial areas would improve the quality of the environment. Unfortunately, this ignores the threat of the remaining waste, which is abandoned and poorly stored. It  represents an even bigger danger because it  stands neglected as it degrades and leaks into the earth without any control at all.
Changes in the water chemistry due to surface water contamination can affect all levels of an ecosystem. It can affect the health of lower food chain organisms and, consequently, the availability of food up through the food chain. It can damage the health of wetlands and damage  their ability to support healthy ecosystems, control flooding, and filter pollutants from storm water runoff. The health of animals and humans are affected when they drink or bathe in contaminated water. In addition water-based organisms, like fish and shellfish, can pile up and concentrate contaminants in their bodies. When other animals or humans eat  these organisms,  they receive a much higher dose of contaminant than they would have if they had been directly exposed to the original contamination.
Contaminated groundwater can badly affect animals, plants and humans if it is removed from the ground by manmade or natural processes. Depending on the study of rocks of the area, groundwater may rise to the surface through springs or seeps, flow sideways into nearby rivers, streams, or ponds, or sink deeper into the earth. In many parts of fhe world, groundwater is pumped  out of the ground to be used for drinking, bathing, other household uses, agriculture, and industry.
Contaminants in the soil can harm plants when they take up the contamination through  their roots. Eating, breathing in, or touching contaminated soil, as well as eating plants or animals that have piled up soil contaminants can badly affect the health of humans and animals.
Air pollution can cause breathing-related problems and other bad health effects as contaminants are absorbed from the lungs into other parts of the  hody. Certain air  contaminants  can also harm animals and humans when they contact the skin. Plants rely on breathing for their growth and can also be affected by exposure to contaminants moved in the air.

According to the passage, which of the followings supports healthy ecosystems?

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:
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.

The Americans with Disabilities Act (ADA) was signed into law in 1990. This law extends civil rights protection to persons with disabilities in private sector employment, all public services, and in public accommodations, transportation and telecommunications. A person with a disability is defined as someone with a mental or physical impairment that substantially limits him or her in a major life activity, such as walking, talking, working, or self-care. A person with a disability may also be someone with a past record of such impairment, for example, someone who no longer has heart disease but is discriminated against because of that history.
The ADA states that employers with fifteen or more employees may not refuse to hire or promote a person because of a disability if that person is qualified to perform the job. Also, the employer must make reasonable accommodations that will allow a person with a disability to perform essential functions of the job.
All new vehicles purchased by public transit authorities must be accessible to people with disabilities. All rail stations must be made accessible, and at least one car per train in existing rail systems must be made accessible.
It is illegal for public accommodations to exclude or refuse persons with disabilities. Public accommodations are businesses and services such as restaurants, hotels, grocery stores and parks. All new buildings must be made accessible, and existing facilities must remove barriers if the removal can be accomplished without much difficulty or expense.
The ADA also stipulates that companies offering telephone service to the general public must offer relay services to individuals who use telecommunications devices for the deaf, twenty-four hours a day, seven days a week.

According to the passage, all of the following are affected by the Americans with Disabilities Act EXCEPT     .

A mansion is a very large home. McDonald's is the name of a fast food hamburger chain. What do you get when you put the two together? You get McMansion, the recently created name for a type of  large suburban, two storied home that originated in the United States. Many people love McMansions for their low price, abundant space and impressive styling, but the news is not all good. In fact, McMansions may now be a threatened species.
McMansion became very popular in the United States during the 1990s, and this popularity continued for almost 20 years. During those years the economy was relatively strong, and banks were willing to lend large sums of money to people who wanted to buy a home. The result was an increase in the average home size. In 1988, the average new American home was 170 square meters, but by 2008 this had risen to 244 square meters, a 44% increase.
To offset the greater costs of these large homes, land developers built many homes that all used a similar basic design and identical construction methods. Framing and interior fittings were constructed in factories, instead of on site, and the materials used were often of a lower quality. Finally, the sections of land used for each house were much smaller than before.
The result was suburban developments full of huge homes, often over 280 square meters in floor area, that all looked similar to each other. Their standardization and lowest possible-cost construction reminded people of McDonald's hamburgers, hence the term McMansion. For many people a McMansion was their dream home, but that dream is now rapidly turning sour.
There are two main problems with McMansions. One problem is that their huge size means that they cost a lot to heat or cool. Energy is becoming more expensive, so owners are faced with huge bills if they try to heat or cool their home. The other problem is that McMansion owners are often in a lot of debt. They borrowed a lot of money to pay for their impressive home, but during the 2000s, with struggling economy and high unemployment, they couldn't afford to repay their loan.
McMansion are still popular in some area, but no one is sure how long it will last. Will energy become even more expensive and force owners to downsize? Will the economy grow and banks become more willing to end again? Will the drop-in house prices allow larger, less affluent families to afford a McMansion? These questions are weighing heavily on the future of one of the most popular housing styles of the late 20th century.

Which of the following statements is NOT true about McMansions?

Bitcoins are a form of virtual currency. In other words, they are a type of money that does not exist in the actual world. However, they can be used to purchase actual products and services from real companies.
The bitcoin system was created in 2009 by an enigmatic person named Satoshi Nakamoto. In fact, no one is sure if Satoshi Nakamoto is an actual person or a group of people. Bitcoins are designed to serve as an alternative to national currencies, such as dollars and euros, They can be used to pay for things instead of cash or credit cards. When bitcoins are transferred from a buyer to a seller, the transaction is recorded in a public database.
Governments are concerned that bitcoins can easily be stolen by hackers. It has dawned on them that they might be used for illegal purposes. For example, stolen goods could be purchased without the government's knowledge. Although more and more companies are beginning to accept bitcoins, the percentage of purchases made using bitcoins is minuscule compared to other online payment methods, such as credit cards. Instead, many bitcoin owners simply keep them as an investment since more valuable in the future.
This may or may not be a wise approach. Currently, the value of bitcoins is fluctuating wildly, especially when compared to highly stable national currencies, Bitcoin Investors are gambling on the hope that as this high-tech money becomes more widely accepted, its value will soar.

Social parasitism involves one species relying on another to raise its young. Among vertebrates, the best known social parasites are such birds as cuckoos and cowbirds; the female lays egg in a nest belonging to another species and leaves it for the host to rear
The dulotic species of ants, however, are the supreme social parasites. Consider, for example, the unusual behavior of ants belonging to the genus Polyergus. All species of this ant have lost the ability to care for themselves. The workers do not forage for food, feed their brood or queen, or even clean their own nest. To compensate for these deficits, Polyergus has become specialized at obtaining workers from the related genus Formica to do these chores
In a raid, several thousand Polyergus workers will travel up to 500 feet in search of a Formica nest, penetrate it, drive off the queen and her workers, capture the pupal brood, and transport it back to their nest. The captured brood is then reared by the resident Formica workers until the developing pupae emerge to add to the Formica population, which maintains the mixed- species nest. The Formica workers forage for food and give it to colony members of both species. They also remove wastes and excavate new chambers as the population increases
The true extent of the Polyergus and dependence on the Formica becomes apparent when the worker population grows too large for existing nest. Formica scouts locate a new nesting site, return to the mixed-species colony, and recruit additional Formica nest mates. During a period that may last seven days, the Formica workers carry to the new nest all the Polyergus eggs, larvae, and pupae, every Polyergus adult, and even the Polyergus queen
Of the approximately 8000 species of ants in the world, all 5 species of Polyergus and some 200 species in other genera have evolved some degree of parasitic relationship with other ants

According to the information in the passage, all of the following terms refer to ants beginning to the genus Formica EXCEPT

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 Roman alphabet took thousands of years to develop, from the picture writing of the ancient Egyptians through modifications by Phoenicians, Greek, Romans, and others. Yet in just a dozen years, one man, Sequoyah, invented an alphabet for the Cherokee people. Bom in eastern Tennessee, Sequoyah was a hunter and a silversmith in his youth, as well as an able interpreter who knew Spanish, French and English.
Sequoyah wanted his people to have the secret of the “talking leaves” as he called his books of white people, and so he set out to design a written form of Cherokee. His chief aim was to record his people’s ancient tribal customs. He began by designing pictographs for every word in the Cherokee vocabulary. Reputedly his wife, angry with him for his neglect of garden and house, burned his notes, and he had to start over. This time, having concluded that picture-writing was cumbersome, he made symbols for the sounds of Cherokee language. Eventually he refined his system to eighty-five characters, which he borrowed from the Roman, Greek, and Hebrew alphabets. He presented this system to the Cherokee General Council in 1821, and it was wholeheartedly approved. The response was phenomenal. Cherokees who had stmggled for months to leam English lettering school picked up the new system in days. Several books were printed in Cherokee, and in 1828, a newspaper, the Cherokee Phoenix, was first published in the new alphabet. Sequoyah was acclaimed by his people.
In his later life, Sequoyah dedicated himself to the general advancement of his people. He went to Washington, D.C, as a representative of the Western tribes. He helped settled bitter differences among Cherokee after their forced movement by the federal government to the Oklahoma territory in the 1930s.
He died in Mexico in 1843 while searching for groups of lost Cherokee. A statue of Sequoyah represents Oklahoma in the Statuary Hall in the Capitol building of Washington, DC. However, he is probably chiefly remembered today because Sequoias, the giant redwood trees of California, are named of him.

According to the passage, how long did it take to develop the Cherokee’s alphabet?
