Read the following passage and choose the best answer (A, B, C, D):
Without regular supplies of some hormones our capacity to behave would be seriously impaired; without others we would soon die. Tiny amounts of some hormones can modify our moods and our action, our inclination to eat or drink, our aggressiveness or submissiveness, and our reproductive and parental behavior. And hormones do more than influence adult behavior; early in life they help to determine the development of bodily form and may even determine an individual’s behavioral capacities. Later in life the changing outputs of some endocrine glands and the body’s changing sensitivity to some hormones are essential aspects of the phenomena of aging. Communication within the body and the consequent integration of behavior were considered the exclusive province of the nervous system up to the beginning of the present century. The emergence of endocrinology as a separate discipline can probably be traced to the experiments of Bayliss and Starling on the hormone secretion. This substance is secreted from cells in the intestinal walls when food enters the stomach; it travels through the bloodstream and stimulates the pancreas to liberate pancreatic juice, which aids in digestion. By showing that special cells secrete chemical agents that are conveyed by the bloodstream and regulate distant target organs or tissues, Bayliss and Starling demonstrated that chemical integration can occur without participation of the nervous system. William Bayliss and Ernest Henry Starling, two British physiologists, discovered and introduced the word hormone. In 1979, The Bayliss and Starling Society was founded as a forum for research scientists with specific interest in the chemistry, physiology and function of central and autonomic peptides. The Society also offered the travelling fellowship award for members who wanted to attend national and international academic conferences. Sometimes, the Society help schools to organize science fairs for secondary students and give them incentives to fall for related subjects. The term “hormone” was first used with reference to secretion. Starling derived the term from the Greek hormone, meaning “to excited or set in motion.” The term “endocrine” was introduced shortly thereafter, “Endocrine” is used to refer to glands that secrete products into the bloodstream. The term “endocrine” contrasts with “exocrine” which is applied to glands that secrete their products through ducts to the site of action. Examples of exocrine glands are the tear glands, the sweat glands, and the pancreas, which secretes pancreatic juice through a duct into intestine. Exocrine glands are also called duct glands, while endocrine glands are called ductless.

Read the following passage and choose the best answer (A, B, C, D):
The comings and goings of teenagers, while a frequent source of tension in the  parent–child relationship, are a crucial experience in the construction of social identities. For this age group, mobility is not just a practice that is socially determined – by social background, residential environment and schooling – but also a specific experience that durably shapes their relationships with the spaces and the social world they encounter.  Although mobility is a socialised practice, based on habits forged in the domestic, residential and school environments, it is itself a specific experience in teenage socialisation. At this age, mobility plays an important role in individuals’ learning of behaviours and ways of being, gradually reshaping the dispositions acquired during primary socialisation.  First of all, mobility affects teenagers’ ways of being and behaving within their peer group, which play an increasingly important role in teenage socialisation. At this age, peers become more and more involved in mobility practices: they are one of the key reasons for mobility but, above all, they become preferred partners in self-mobility situations.  Furthermore, the movements of teenagers, alone or in groups, gradually reshapes their dispositions vis-à-vis mobility, particularly those acquired in the domestic sphere. At this age, experiences in mobility have lasting effects on the future practices of teenagers. They sometimes help modify the dispositions of teenagers regarding transport modes. We could cite, among other examples, the case of a girl whose fear of the metro gradually diminished as a result of occasional trips with her best friend, who was more familiar with this mode of transport. These experiences also influence the spatial amplitude of future mobility, in particular preferences for travel within or outside one’s area of residence.  Lastly, mobility allows teenagers to discover the public domain, when it gives rise to interactions that take place under the gaze of an incidental audience and which are therefore subject to specific rules. In the course of their travels, teenagers gradually become familiar with these rules, and they mutually adapt their behaviours to those of other citizens so as to eventually find their place within the public domain. Listening to music on mobile phones on public transport, for example, is appropriate to a greater or lesser extent, depending on the circumstances at the time.
6. Which of the following statements is TRUE, according to the passage?

Read the following passage and choose the best answer (A, B, C, D):
If you were going to choose a job that involves travel, what would be your first choice? There are many jobs available today that give people opportunities to travel. Although may traveling careers sound fantastic, they also have disadvantages. Being an au pair is an excellent way to not only go to different countries, but to live in different places around the world and really get a feel for the culture. Au pairs lives with the families they are placed with and take of children. Many parents include au pairs in family events and vacations, so they experience many aspects of the new culture while on the job. However, many of the activities are centered around the children, so they may not get to experience many things that interest adults. For people who want a bit more freedom working abroad, being an English teacher maybe a good choice. There are English teaching jobs in almost countries in the world. People teaching English in other countries often have a chance to travel on the weekends around the country. One drawback is that many teachers often wind up hanging out with other English teachers, and they don’t have time to learn the country’s language. The nickname “roadie” implies that this job involves life on the road. Roadies are people who work and travel with bands and provide technical support. Roadies can be lighting and stage crew who set up the stage and break it down before and after events. They can also be technicians helping band members with their instruments. International tours take a band’s crew to cities around the world, often requiring air travel. However, the crew doesn’t get much time off, so they may travel to several countries without seeing much besides concert venues and hotels. Similarly, flight attendants often travel to cities around the world, but they don’t see much besides the inside of airplanes and hotels. However, when they do have time off, they can often fly at no cost, and family member can sometimes fly free as well. Its is widely thought that a flight attendant job is glamorous, but flight attendants must deal with travel hassles, as well as security issues. All jobs gave advantages and disadvantages whether or not you travel for work, so if you have the travel bug, keep these jobs in mind for the future.
8. It can be inferred from the passage that _______

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  
2. What is the synonym of the word “repercussions” in the first paragraph?

Read the following passage and choose the best answer (A, B, C, D):
Most people have heard about how PTSD can unravel a person. Fewer have heard about posttraumatic growth, the process that lifted Curry out of his despair and into his new role as a leader in the veteran community. The term - defined as “positive change that occurs as a result of the struggle with highly challenging life crises” - was coined in the mid-1990s by Richard Tedeschi, PhD, and Lawrence Calhoun, PhD, after studying how people develop wisdom. They identified five specific ways people can grow after a crisis. First, their relationships strengthen. One woman diagnosed with breast cancer, for example, said she realized her relationships “are the most important things you have.” Bereaved parents told Tedeschi and Calhoun that losing a child had made them more compassionate. Second, they discover new paths and purposes in life. Sometimes these are related to a particular survivor mission. One interviewee became an oncology nurse after losing her child to cancer. Other times, the crisis becomes the catalyst for a more general reconsideration of priorities, as Christine discovered when she started attending The Dinner Party in the aftermath of her mother’s death. Third, the trauma allows them to find their inner strength. The common thread among those Tedeschi and Calhoun studied is a “vulnerable yet stronger” narrative. This paradoxical outlook defined the attitude of a rape survivor who admitted the world seemed more dangerous after the assault, but that, at the same time, she felt more resilient as a result of the inner strength she’d built. Fourth, their spiritual life deepens. That could mean they renew their faith in God, or it could mean they grapple with existential questions more broadly, coming to know certain deep truths about the world or themselves, as one interviewee did after his spinal-cord surgery. Finally, they feel a renewed appreciation for life. Rather than taking for granted a stranger’s kindness or the vivid colors of autumn leaves, they savor the small moments of beauty that light up each day. The difference between those who are able to grow from adversity and those who are stymied lies in what Tedeschi and Calhoun call “deliberate rumination” or introspection. The participants they studied spent a lot of time trying to make sense of their painful experiences, reflecting on how the events changed them. Doing so helped them make the life changes associated with posttraumatic growth.

Read the following passage and choose the best answer (A, B, C, D):
During droughts water is scarce but is it possible to make it rain to provide water. Experiments in cloud seeding suggest that it may be possible to artificially create rainfall. Rainfall occurs when supercooled droplets of water – those that are still liquid but are at a temperature below the usual freezing point of zero centigrade – form ice crystals. Now too heavy to remain suspended in the air, these then fall, often melting on their way down to form rain. Even in dry areas the air usually contains some water. This can be made to come together and form ice crystals by seeding the atmosphere with chemicals such as silver iodide or dry ice. They work to promote rainfall by inducing nucleation – what little water is in the air condenses around the newly introduced particles and crystallises to form ice. The ‘seeds’ can be delivered by plane or simply by spraying from the ground. But does it work? It’s hard to tell for sure. As is often the case with weather and climate, it’s impossible to carry out a controlled experiment – so, in areas of increased precipitation, we can’t know whether it would still have rained even if the clouds hadn’t been seeded. Success has been claimed for trials in Australia, France, Spain and the US. In the United Arab Emirates, the technique is credited with the creation of 52 storms in the Abu Dhabi desert, while China boasts of having used the technology in reverse to keep the Beijing Olympic Games of 2008 dry. Recent research, however, suggests that it’s not as effective as was previously believed

There is a scam aimed at a child’s desire to be a published writer - usually as a poet, in a book of poems. How does the scam work? Keen teachers are unwittingly caught up in the promotion but are completely unaware of the dodgy side of the scheme. There are plenty of honest opportunities for children’s writing that don’t cost their parents a small fortune and provide a poor-quality product. Most books in scams are badly set out. They tend to be huge volumes, squashing in as many writers’ efforts as possible to make as much money as possible. They’re an embarrassment for the young poets. These competitions to discover hidden talent sound great in the glossy flyers. Schools too are offered a prize if a winner is from their school. Schools become unpaid ‘agents’ in promotion of the competitions. Parents are happy to pay a small entry fee. Each child hopes to get an ‘honourable mention’ with the possibility of being selected to be included in a book. The price of the book is not given. Naturally, if a child’s work were published, parents would want a copy of the book. In one such scheme the pre-order price was $67 with an extra $26 if the child’s photo was included. That’s nearly $100! Strangely, awards are given to those who pre-order a book! The books are not attractive. A copy at a market sold for $2. There were three to five kids’ poems squashed on a page, with over 3000 poems jammed into that one book. Clip Art was used to illustrate the poor publication. Look at the maths. 3000 kids multiplied by $100 equals $300 000. Now add the entry fees of, say, $2 - add another $6000! Enough to cover publicity! One place winner’ was upset when the parents realised this was a con to buy a book, but not buying the book made the parents feel guilty. Genuine competitions that publish books give a free copy to any ‘winner’

Most people think that lions only come from Africa. This is understandable because in fact most lions do come from there but this has not always been the case. If we went back ten thousand years, we would find that there were lions roaming vast sections of the globe. However now, unfortunately only a very small section of the lion's former habitat remains.
Asiatic lions are sub-species of African lions. It is almost a hundred thousand years since the Asiatic lions split off and developed as a sub-species. At one time the Asiatic lion was living as far west as Greece and they were found from there, but in a band that spreads east through various countries of the Middle East, all the way to India. In museums now, you can see Greek coins that

have clear images of the Asiatic lion on them. Most of them are dated at around 500 B.C. However, Europe saw its last Asiatic lions roaming free two thousand years ago. Over the next nineteen hundred years the numbers of Asiatic lions in the other areas declined steadily, but it was only in the nineteenth century that they disappeared from everywhere but in India.
The Gir Wildlife Sanctuary in India was established especially to protect the Asiatic lion. There are now around three hundred Asiatic lions in India and almost all of them are in this sanctuary. However, despite living in a sanctuary, which makes them safe from hunters, they still face a number of problems that threaten their survival. One of these is the ever-present danger of disease. This is what killed more than a third of Africa’s Serengeti lions in 1994, and people are fearful that something similar could happen in the Gir Sanctuary and kill off many of the Asiatic lions there.
India's lions are particular vulnerable because they have a limited gene pool. The reason for this is interesting is because all of them are descended from a few dozen lions that were saved by a prince who took a particular interest in them. He was very healthy, and he managed to protect them; otherwise they would probably have died out completely.
When you see the Asiatic lion in India, what you sense is enormous vitality. They are very impressive animals and you would never guess that they have this vulnerability when you look at them.

The blazes, which have been burning across Australia for months, have razed homes  and wiped out entire towns. Across Australia, nearly 18 million acres of land have been burned – much of it bushland, forests and national parks, home to the country’s beloved and unique wildlife. Nearly half a billion animals have been impacted by the fires in NSW alone, with millions potentially dead, according to ecologists at the University of Sydney. That figure includes birds, reptiles, and mammals, except bats. It also excludes insects and frogs. The total number of animals affected nationwide could be as high as a billion, according to Christopher Dickman, the University of Sydney ecologist who led the report.  "The scale of these fires is unprecedented," said Dieter Hochuli, an environmental sciences professor at the University of Sydney. “There are substantial concerns about the capacity of these (ecosystems) to rebound from the fires.”  Some animals, like koalas and kangaroos for instance, are primarily killed by being incinerated in flames or choking on smoke. Nearly a third of all koalas in NSW have died and about a third of their habitat has been destroyed. Photos from the ground show koalas with singed fur, raw patches of burnt flesh, and blistered paws. Even if they are rescued and treated, sometimes their injuries are simply too extensive to survive. Wombats have also been hit hard – they don’t cope well with heat or stress, and panic at the smell of smoke. The small, stubby-legged marsupials can’t run very fast or far, and are largely at the mercy of the flames. Smaller mammals and reptiles can escape the blazes by burrowing underground or hiding in rocks – but afterward, there is no food or shelter left, only certain predators that are drawn to fire because they know it brings easy prey. Koalas and kangaroos are spread out across the country, so they’re not in danger of going extinct due to the blazes. But other animals that live in niche environments and have smaller populations may have been wiped out entirely; these include the eastern bristlebird, the mountain pygmy possum and the corroboree frog.  These animals’ recovery depends not only on their population size, but also on the condition of their habitat. For instance, plants grow slower in high-altitude alpine regions, meaning it could be a very long time before species are able to return.

Read the following passage and choose the best answer (A, B, C, D):
Hardcover and paperback are two types of books and bookbinding processes. A hardcover book is also called a hardback or hardbound. On the other hand, a paperback also goes by the names softback and soft cover. Paperbacks can be further classified as trade paperbacks and mass-market paperbacks. Paperback book, as its name implies, has a soft card or a thick paper cover over the pages. This type of covering is less heavy but prone to folding, bending, and wrinkles with use and over time. Hardcover books are characterized with a thick and rigid covering. This covering allows protection for the pages and makes the book durable and usable for a long time. Oftentimes, a hardcover book has a dust that protects the books from dust and other wear and tear. Some books are even made durable by using leather or calfskin as a book covering. In terms of manufacturing and purchasing books, hardcover books are more expensive due to the materials and processes. Pages of hardcover books are acid-free paper. This type of paper allows preservation of the ink and is ideal for books in use and preserving them for a long time. On the other hand, paperbacks use cheap paper, usually newsprint. The reason for this is to lower production costs and being readily made available for the masses. The paper in a hardcover book is usually stitched together before being glued, stapled, or sewn to the book’s spine. Due to the stitches, a hardcover book can have signatures, a place where the binding threads are visible. Meanwhile, a paperback book’s pages are glued together and glued again to the spine. This makes the pages loose or separated while being in use. Hardcover books are often applied to academic books, references books, commercial, and bestsellers that have enjoyed financial success. Other books in the hardcover version are books of collectible value. Publishers often release a hardcover version of the book to show investment so that they can project a high return of investment. This is a large contrast regarding paperbacks. Paperback books are done for new or succeeding editions, reprinting of books or books with little profit margin. Publishers use the paperback editions to stretch the profit for the book. The first release or first edition of a literary work is purposefully done as a hardcover book followed by paperback versions.

Read the following passage and choose the best answer (A, B, C, D):
Diseases are a natural part of life on earth. If there were no diseases, the population would grow too quickly, and there would not be enough food or other resources, so in a way, diseases are natural ways of keeping the Earth in balance. But sometimes they spread very quickly and kill large numbers of people. For example, in 1918, an outbreak of the flu across the world, killing over 25 million people only in six months. Such terrible outbreaks of a diseases are called pandemics. Pandemics happen when a disease changes in a way that our bodies are not prepared to fiht. In 1918, a new type of fl virus appeared. Our bodies had no way to fiht this new flu virus, and so it spread very quickly and killed large numbers of people. While there have been many different pandemic diseases throughout history, all of them have a new thing in common. First, all pandemic diseases spread from one person to another very easily. Second, while they may kill many people, they generally do not kill people very quickly. A good example of this would be the Marburg virus. The Marburg virus is an extremely infectious disease. In addition, it is deadly. About 70%-80% of all people who get the Marburg virus died from the disease. However, the Marburg virus has not become a pandemics because most people die within three days of getting the disease. This means that the virus does not have enough time to spread a large number of people. The flu virus of 1918, on the other hand, generally took about a week to ten days to kill its victims, so it had more time to spread. While we may never be able to completely stop pandemics, we can make them less common. Doctors carefully monitor new disease that they fear could become pandemics. For example, in 2002, and 2003, doctors carefully watched SARS. Their health warming may have prevented SARS from becoming a pandemic.
