Read the following passage and choose the best answer (A, B, C, D):
Aging is the process of growing old. It occurs eventually in every living thing provided, of course, that an illness or accident does not kill it prematurely. The most familiar outward signs of aging may be seen in old people, such as the graying of the hair and the wrinkling of the skin. Signs of aging in a pet dog or cat include loss of playfulness and energy, a decline in hearing and eyesight, or even a light graying of the coat. Plants are too, but the signs are much harder to detect. Most body parts grow bigger and stronger, and function more effiiently during childhood. They reach their peak at the time of maturity, or early adulthood. After that, they begin to decline. Bones, for example, gradually become lighter and more brittle. In the aged, the joints between the bones also become rigid and more inflxible. This can make moving very painful. All the major organs of the body show signs of aging. The brain, for example, works less effiiently, and even gets smaller in size. Thinking processes of all sorts are slowed down. Old people often have trouble in remembering recent events. One of the most serious changes of old age occurs in the arteries, the blood vessels that lead from the heart. They become thickened and constricted, allowing less blood to flw to the rest of body. This condition accounts, directly or indirectly, for many of the diseases of the aged. It may, for example, result in heart attack. Aging is not a uniform process. Different parts of the body wear out at the different rates. There are differences among people in their rate of aging. Even the cell of the body differ in the way they age. The majority of cells are capable of reproducing themselves many times during the course of a lifetime. Nerve cells and muscle fiers can never be replaced once they wear out. Gerontologists - scientists who study the process of aging - believe this wearing out of the body is controlled by a built-in biological time-clock. They are trying to discover how this clock works so that they can slow down the process. This could give man a longer life and a great number of productive years.

Gujarat’s favourite watering hole, Union territory of Daman, will add more activity  for its tourists than let them hang around only in the bars on its sun-kissed beaches. The administration has decided to develop leisure water sports on Jampore and Light house beaches at Moti Daman. The tourism department of Daman has already selected two operators to run these leisure water sports facilities. At present, facilities like creation of ramps, walking area and waiting area for the tourists are under construction at the beaches.  Director of Daman Tourism, Harshil Jain told TOI, “The leisure water sports activities are all set to start very soon. We have not decided the dates, but the contractors are working day-and-night to set up facilities soon at both the beaches.” He further said that leisure water sports will help boost tourism in Daman. “The flow of tourist will increase during the vacation period. Till now, tourists come here to enjoy sitting on the beaches, but now they will have the option for water sports, too,” Jain added.  According to tourism department officials, the sporting activity would be set up on the lines of Goa. Attractions like jet skis, banana ride, para sailing, pedal boating, rowing, kayaking and motorboating will add to the beach fun, they said. A senior tourism officer said, “Since adventure has a risk factor, we have asked the contractors to keep provision of accidental insurance cover for all the tourists using the ride. Customers too must be covered for accidental death, loss of limb and permanent and partial disability.” “On the weekends alone, more than 60,000 people visit Daman. We are pretty sure that the water sports activity will increase the numbers to more than 80,000,” asserted another official.

Read the following passage and choose the best answer (A, B, C, D):
The Colosseum was constructed over a short decade, between 70-80 AD, by up to  100,000 slaves. Its building was overseen by different emperors who ruled under the Imperial Flavian dynasty, lending the structure its original name. Emperor Vespasian began the construction of the Flavian Amphitheater and his son Titus oversaw the construction of an additional tier after his death in 79 AD. His youngest son Domitian constructed the underground tunnels and added an extra level to increase its seating capacity. The amphitheater takes its more commonly attributed name from the Colossus of Nero, an enormous bronze statue of the Emperor which was located beside the structure.  The Colosseum was a recreational and gathering space that was used for gladiatorial contests, public spectacles, historical re-enactments, mythological theatrical performances and of course, executions. It could hold between 50,000 to 80,000 spectators and the seating arrangements reflect the stratification of Roman society: senators were seated closest to the stage while the poorest Roman citizens (and women) stood at the highest level. Its skilled architects developed an ingenious design which included 80 entrances and exits with a numbering system to allow access in and out of the structure. Unlike most ancient amphitheaters which were built into hillsides for support, the Colosseum is so impressive because it is a freestanding structure: it is made of travertine stone that was sourced from the nearby Tivoli area and held together with iron clamps.  The Colosseum is most closely associated with its gladiatorial shows, although often the combatants were not skilled professionals but rather unlucky slaves and criminals pitted against each other for the enjoyment of the public. In fact the venatio, or animal hunt, was one of the most popular shows for its novelty and shock appeal. Always in pursuit of ostentatious displays of wealth and power, the Romans procured exotic animals such as elephants, giraffes, lions, bears and crocodiles from the far reaches of the empire and sent them out into the pit, often along with unfortunate souls who would be torn to pieces. During the inaugural games of the Colosseum, most likely held in 80 AD, over 9,000 animals are believed to have been killed. The Romans also constructed elaborate stage sets on the arena floor, simulating forests and other natural environments, as backdrops to the events taking place.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the following questions:
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.

How is a flight attendant’s job similar to a roadie’s?

As a result of the recent oil crisis, 9.9 million of California’s 15 million motorists were subjected to an odd – even plan of gas rationing. The governor signed a bill forcing motorists with license plates ending in odd numbers to buy gas only on odd – numbered days, and those ending in even numbers on even – numbered days. Those whose plates were all letters or specially printed had to follow the odd – numbered plan.
Exceptions were made only for emergencies and out – of – state – drivers. Those who could not get gas were forced to walk, bike, or skate to work.
This plan was expected to eliminate the long lines at many service stations. Those who tried to purchase more than twenty gallons of gas or tried to fill a more than half filled tank would be fined and possibly imprisoned.

California was forced to adopt this plan because

A new study shows that urbanization shifts this seasonal cue in nuanced ways, with cities in cold climates triggering earlier spring plant growth and cities in warm climates delaying it. The study also found that the urban heat island effect, the phenomenon in which cities are warmer than their surroundings, is not the only culprit behind the shift, suggesting that other aspects of urbanization, such as pollution, changes in humidity and fertilizer runoff, may also influence plants’ seasonal patterns.  Researchers analyzed millions of observations of 136 plant species across the U.S. and Europe to study how regional temperature and the local density of people-a proxy for urbanization—affect when plants sprout leaves and blossoms. Their results revealed a complex story: Separately, warmer temperatures and higher population density each spurred earlier springs. A 3.6-degree Fahrenheit increase in temperature bumped up plants’ production of leaves and flowers by about five and six days, respectively. A fourfold increase in human population density advanced flowering and leaf production dates by about three days. But the team found that when these two factors worked together, local temperature had an outsized influence. In cold regions—areas with an average November-to-May temperature of about 18 degrees-plants produced leaves and flowers about 20 days earlier in locations with about 26,000 people per square mile, compared with equally frigid wildland. When an area’s average November-to-May temperature jumped to 68, however, leaves and flowers appeared four and six days later, respectively, in locations with about 26,000 people per square mile, compared with equally balmy wildland. In New York, for example, plants are likely sprouting leaves about 9.5 days earlier and blossoms eight days earlier than uninhabited regions with the same temperature. Jacksonville, in contrast, is likely pushing leaf production later by about one day and flowers by about half a day, with leaves appearing two days later and flowers a day later in Houston.  Even after accounting for urban heat islands, the team’s models revealed cities significantly affect plants’ springtime growth. “Not only are there other things going on, but they actually matter quite a lot,” said study co-author Brian Stucky, Florida Museum research scientist. Plants may not be the only organisms affected by seasonal shifts, he added. “Seasons are such a big part of our lives. We define our world around seasonal things. Those rhythms are what we think of as the normal way the world works.” 
7. Which of the following statements is TRUE, according to the passage?

Read the following passage and choose the best answer (A, B, C, D):
Light-emitting diodes (LEDs) are now considered the future of lighting due to a lower energy requirement to run, a lower monthly price tag, and a longer life than traditional incandescent light bulbs. Nick Holonyak, an American scientist at General Electric, accidently invented the red LED light while trying to create a laser in the early 1960s. As with other inventors, the principle that some semiconductors glowed when an electric current was applied had been known since the early 1900s, but Holonyak was the first to patent it for use as a light fixture. Within a few years, yellow and green LEDs were added to the mix and used in several applications including indicator lights, calculator displays, and traffic lights, according to the DOE. The blue LED was created in the early 1990s by Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura, a group of Japanese and American scientists, and for which they won the 2014 Nobel Prize in Physics. The blue LED allowed scientists to create white LED light bulbs by coating the diodes with phosphor Today, lighting choices have expanded and people can choose different types of light bulbs, including compact fluorescent (CFL) bulbs work by heating a gas that produces ultraviolet light and LED bulbs. Several lighting companies are pushing the boundaries of what light bulbs can do, including Phillips and Stack. Phillips is one of several companies that have created wireless light bulbs that can be controlled via smartphone app. The Phillips Hue uses LED technology that can quickly be turned on or off or dimmed by a flick on a smart phone screen and can also be programmed. The higher-end Hue light bulbs can even be set to a large range of colors (only about sixteen million) and synced with music, movies, and video games. Stack, begun by engineers from Tesla and NASA, developed a smart light bulb using LED technology with a wide range of functions. It can automatically sense the ambient lighting and adjust as needed, it turns off and on via motion sensor when someone enters the room, can be used as a wake up alert, and even adjusts color throughout the day to fit with human’s natural circadian cycles and patterns of natural light. The light bulbs also have a built-in learning program that adapts to inputs given by residents over time. And all of these functions can be programmed or monitored from any smart phone or tablet. It is estimated that Stack smart light bulbs can use about sixty percent less energy than a typical LED light bulb and lasts between twenty and thirty thousand hours depending on the model . These light bulbs are compatible (or soon will be) with many of the options for turning an entire home into a smart home including usage with Amazon Alexa, Google Home, and Apple HomeKit.
5. According to paragraph 5, what can be done with the higher-end Hue light bulbs?

October brings attention to breast cancer, by raising awareness of treatment, research  and prevention. One local company is going a step above the rest, by offering a free home cleaning to a patient undergoing treatment. Cleaning for a Reason is an international organization that provides home cleanings for family members battling cancer.  “I am a breast cancer survivor myself, I was diagnosed in 2011. And so when I found out about this in 2014, after going through my experience of being extremely tired and just no energy at all to perform day to day tasks, that I realized this would be something that would greatly benefit the women in our community,” said Marlo Kanipe, owner of Deserved Comfort House Cleaning. The company partners with Cleaning for a Reason to provide the service locally.  Columbia native Lenora Floyd was diagnosed with breast cancer in 2018, and learned about Cleaning for a Reason from a flyer. “I was sitting at the table and I thought ‘that’s really something that would be such a huge help!’ Because I do most of the cleaning around the house, and I didn’t really know what to expect,” said Floyd. Floyd said having a clean home lifted a burden while she was going through a tough time. “It was just really nice to have that service, and one less thing not to have to worry about. Be able to rest instead of thinking ‘oh, I really need to vacuum up,’” said Floyd. “The chemotherapy and radiation really just takes a toll on your body. When someone is going through those times, the last thing you want to do is to have to do physical work. And house cleaning, of course, is physical work,” said Kanipe. “It’s nice to be able to take one small thing off of their plate. That they don’t have to worry about cleaning or keeping their house clean,” said Nicka Evans, a certified cleaning technician with Deserved Comfort. “This is what I do for work, it doesn’t seem like it’s a big deal. But to be able to come into someone’s house and see that it is a big deal and it’s important to them, it really means a lot to me.”  Since partnering with Cleaning for a Reason in 2014, Deserved Comfort has donated about $15,000 worth of cleanings. They will continue to help and be there for people as they battle cancer.
4. According to paragraph 4, what is the motive behind the organization’s work?

Read the following passage and choose the best answer (A, B, C, D):
Deforestation has important global consequences. Forests sequester carbon in the  form of wood and other biomass as the trees grow, taking up carbon dioxide from the atmosphere. When forests are burned, their carbon is returned to the atmosphere as carbon dioxide, a greenhouse gas that has the potential to alter global climate, and the trees are no longer present to sequester more carbon.  In addition, most of the planet’s valuable biodiversity is within forests, particularly tropical ones. Moist tropical forests such as the Amazon have the greatest concentrations of  animal and plant species of any terrestrial ecosystem; perhaps two-thirds of Earth’s species live only in these forests. As deforestation proceeds, it has the potential to cause the extinction of increasing numbers of these species.  On a more local scale, the effects of forest clearing, selective logging, and fires interact. Selective logging increases the flammability of the forest because it converts a closed, wetter forest into a more open, drier one. This leaves the forest vulnerable to the accidental movement of fires from cleared adjacent agricultural lands and to the killing effects of natural droughts. As wildfires, logging, and droughts continue, the forest can become progressively more open until all the trees are lost. Additionally, the burning of tropical forests is generally a seasonal phenomenon and can severely impact air quality. Record-breaking levels of air pollution have occurred in Southeast Asia as the result of burning for oil palm plantations.  In the tropics, much of the deforested land exists in the form of steep mountain hillsides. The combination of steep slopes, high rainfall, and the lack of tree roots to bind the soil can lead to disastrous landslides that destroy fields, homes, and human lives. With the significant exception of the forests destroyed for the oil palm industry, many of the humid forests that have been cleared are soon abandoned as croplands or only used for lowdensity grazing because the soils are extremely poor in nutrients. The vegetation that contains most of the nutrients is often burned, and the nutrients literally “go up in smoke” or are washed away in the next rain. Although forests may regrow after being cleared and then abandoned, this is not always the case, especially if the remaining forests are highly fragmented. Such habitat fragmentation isolates populations of plant and animal species from each other, making it difficult to reproduce without genetic bottlenecks, and the fragments may be too small to support large or territorial animals. Furthermore, deforested lands that are planted with commercially important trees lack biodiversity and do not serve as habitats for native plants
and animals, many of which are endangered species.

The Broadway hit “Hamilton” earned $1.9 million in ticket sales per week, according to The New York Times. “Hamilton” was awarded the 2016 Pulitzer Prize in Drama and it won 11 Tony awards out of 16 nominations, according to broadway.com. Lin-Manuel Miranda, 37, who created the show and starred as Alexander Hamilton, grew up in New York, immersed in music and performance art, although his family could rarely afford Broadway show tickets, according to published biographies. He watched “Les Miserables” at age 7, and fell in love with the art form. He starred in “Pirates of Penzance” during high school, and took a liking to hip-hop and R&B. Miranda went to Wesleyan University, where he studied theater, appeared on stage and drafted his own work. He was cast as the lead in the 2007 off-Broadway musical “In the Heights,” which eventually went to Broadway in 2008. That show earned four Tony Awards and was nominated for the drama category of the Pulitzer Prize, according to published reports. Miranda was encouraged to be a lawyer at a young age, but he always shined when performing, according to playbill.com. As a young adult, he came to a dilemma that would change his life. He was substitute teaching at Hunter College High School, his alma mater, and was offered a position as a part-time English teacher there. He was torn between taking the safe job or pursuing writing. Miranda turned to his father and asked, “What should I do? Should I keep teaching or should I just kind of sub and do gigs to pay the rent and really throw myself into writing full time?” His father answered his question in a letter: “I really want you to keep the job - that’s the smart “parent thing” to do - but when I was 17, I was a manager at Sears in Puerto Rico, and I basically threw it all away to go to New York (and) I didn’t speak a lot of English. It made no sense, but it was what I needed to do. It makes no sense to leave your job to be a writer, but I have to tell you to do it. You have to pursue that if you want." Miranda declined the part-time teaching job, threw himself into writing and “Hamilton!” was born.

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

Myriad occupational schools in the central coastal city of Da Nang have received just a small number of applications over the past few years. “Last year we only had 142 new students, but the number of new enrollees is 50 this school year,” Truong Van Hung, rector of the Duc Tri Da Nang Vocational College, said, adding the school has set a target of recruiting 1,200 students for the 2014-2015 academic year. “Closing the school is just a matter of time,” he said. Similarly, the Viet A Vocational School in Hai Chau District in Da Nang has not recruited any new enrollee for over one year given the absence of job opportunities for its graduates. “We do not want to enroll because we cannot help students land jobs after they graduate,” a leader of Viet A said. “We will only admit new students when we can have a partnership with companies who can employ our students after they finish their studies.” Elsewhere, vocational schools in the southern province of Dong Nai are ‘frozen’. The Dong Nai Information Technology-Telecommunications Vocational School in the academic year of 2013-2014 enrolled only 82 students compared with a target of 1,000; the Nhon Trach Industrial Engineering Vocational School only had 200 out of its goal of 600 students for the school year; the 26-3 Vocational School received 150 students while they set a target of 250; and the South-Eastern Electromechanical Vocational School only recruited 300 out of the 500 students they planned to admit. The situation means that equipment for training programs at those schools has been left unused and covered with rust. Local experts have commented that if the lack of students persists, vocational schools are at high risk of being closed, sooner or later.

Read the following passage and choose the best answer (A, B, C, D):
Global sea level has been rising over the past century, and the rate has increased in recent decades. In 2014, global sea level was 2.6 inches above the 1993 average-the highest annual average in the satellite record (1993-present). Sea level continues to rise at a rate of about one-eighth of an inch per year. Higher sea levels mean that deadly and destructive storm surges push farther inland than they once did, which also means more frequent nuisance flooding. Disruptive and expensive, nuisance flooding is estimated to be from 300 percent to 900 percent more frequent within U.S. coastal communities than it was just 50 years ago. The two major causes of global sea level rise are thermal expansion caused by warming of the ocean since water expands as it warms, and increased melting of land-based ice, such as glaciers and ice sheets. The oceans are absorbing more than 90 percent of the increased atmospheric heat associated with emissions from human activity. With continued ocean and atmospheric warming, sea levels will likely rise for many centuries at rates higher than that of the current century. In the United States, almost 40 percent of the population lives in relatively high-population-density coastal areas, where sea level plays a role in flooding, shoreline erosion, and hazards from storms. Globally, eight of the world’s 10 largest cities are near a coast, according to the U.N. Atlas of the Oceans. Sea level rise at specific locations may be more or less than the global average due to local factors such as land subsidence from natural processes and withdrawal of groundwater and fossil fuels, changes in regional ocean currents, and whether the land is still rebounding from the compressive weight of Ice Age glaciers. In urban settings, rising seas threaten infrastructure necessary for local jobs and regional industries. Roads, bridges, subways, water supplies, oil and gas wells, power plants, sewage treatment plants, landfills-virtually all human infrastructure-is at risk from sea level rise.
