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.

   Thanksgiving is celebrated in the US on the fourth Thursday in November. For many Americans it is the most important holiday apart from Christmas. Schools, offices and most businesses close for Thanksgiving, and many people make the whole weekend a vacation.

   Thanksgiving is associated with the time when Europeans first came to North America. In 1620 the ship the Mayflowers arrived, bringing about 150 people who today are usually called Pilgrims. They arrived at the beginning of a very hard winter and could not find enough to eat, so many of them died. But in the following summer Native Americans showed them what foods were safe to eat, so that they could save food for the next winter. They held a big celebration to thank God and the Native Americans for the fact that they had survived.

   Today people celebrate Thanksgiving to remember these early days. The most important part of the celebration is a traditional dinner with foods that come from North America. The meal includes turkey, sweet potatoes (also called yams) and cranberries, which are made into a kind of sauce or jelly. The turkey is filled with stuffing or dressing, and many families have their own special recipe. Dessert is pumpkin made into a pie.

   On Thanksgiving there are special television programs and sports events. In New York there is the Macy's Thanksgiving Day Parade, when a long line of people wearing fancy costumes march through the streets with large balloons in the shape of imaginary characters. Thanksgiving is considered the beginning of the Christmas period, and the next day many people go out to shop for Christmas presents.

Which of the following is NOT true?

Almost as soon as World War II ended, the debate began over who had actually done the  most on the Allied side to ensure the defeat of the Axis powers. The Russians only needed to point to their twenty million plus war dead to justify their rights in Eastern Europe and their new  position as a great power on the world stage. Yet, Americans could also claim that they had done as much, if not more, as the Russians to defeat the Axis enemy. In hindsight, it is obvious that  despite its greater number of dead, the Russian effort ranks second place to the American. In  particular, the American effort seems greater in light of three crucial points: it was fighting at  extreme distances from its home territory; it simultaneously fought three different enemies on a multitude of complex fronts with air, naval, land forces; and finally, it supplied many other fighting  forces, including the Russians, with massive amounts ofmaterial. 

The main fronts of World War II were in North Africa, Italy, Western and Eastern Europe, the Pacific Ocean, China, and India. The United States military forces fought on or supported  every front, all of which were at extreme distances from the continental United States. A great logistical effort required to support both its own forces and those of many other nations. Above all,  supply ships were essential because without the supply ships, all would have been in vain.  Keeping the world's sea lanes free was one of the great accomplishments of the United States  Navy and her allies, especially the British and Canadians. This allowed ships to traverse great  distances and bring American and other Allied fighting forces to face the Axis powers. The Russians, on the other hand, were  fighting in their own country for much of the war and were close to their supply lines. They fought on one continuous font and did not have to travel far to meet the enemy. 

The United States fought all three great Axis powers during the war: Germany, Japan, and  Italy. While it cannot be denied that the Russian did the lion's share of the fighting against  Germany and the lesser Axis powers of Finland, Hungary, Romania, and Bulgaria for a longer  time, it was not until the last days of the war that Russia attacked Japan. As for the Italians, the  Russians only met the reluctant few whom Hitler managed to coerce for his Russian campaign. Another area to take into consideration is the strategic bombing campaign that the Americans and  British waged against German industry, something that the Russians did not take part in at all.  Finally, with the exception of the Baltic Sea, the Russian navy played a very minor role in the war  compared to American's navy. Despite significant aid from the British, Australians, and New Zealanders, the Americans bore the brute of the Pacific fighting. 

The Chinese tied down a massive number of Japanese troops on the Asian mainland, but  they were supplied almost exclusively by the United States. American arms, support equipment,  food, and clothing went to the four corners of the world during the war even before American officially entered it in 1941. Indeed, the Russian Red Army rode into Eastern Europe on the wheels  of over 300,000 American trucks, fed itself on a diet of American canned ham, and wore 

American boots. Coupled with all this were billion-dollar loans with generous terms of interest, which America gave to its allies. American was the only Allied nation that did not need to borrow  any money during the war. 

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.

   A rather surprising geographical feature of Antarctica is that a huge freshwater lake, one of the world’s largest and deepest, lies hidden there under four kilometers of ice. Now known as Lake Vostok, this huge body of water is located under the ice block that comprises Antarctica. The lake is able to exist in its unfrozen state beneath this block of ice because its waters are warmed by geothermal heat from the earth’s core. The thick glacier above Lake Vostok actually insulates it from the frigid temperatures on the surface.

   The lake was first discovered in the 1970s while a research team was conducting an aerial survey of the area. Radio waves from the survey equipment penetrated the ice and revealed a body of water of indeterminate size. It was not until much more recently that data collected by satellite made scientists aware of the tremendous size of the lake; the satellite-borne radar detected an extremely flat region where the ice remains level because it is floating on the water of the lake.

   The discovery of such a huge freshwater lake trapped under Antarctica is of interest to the scientific community because of the potential that the lake contains ancient microbes that have survived for thousands of years, unaffected by factors such as nuclear fallout and elevated ultraviolet light that have affected organisms in more exposed areas. The downside of the discovery, however, lies in the difficulty of conducting research on the lake in such a harsh climate and in the problems associated with obtaining uncontaminated samples from the lake without actually exposing the lake to contamination. Scientists are looking for possible ways to accomplish this.

It can be inferred from the passage that the ice would not be flat if______.

Which of the following is closest in meaning to “frigid” in paragraph 1?

Large animals that inhabit the desert have evolved a number of adaptations for reducing the effects of extreme heat. One adaptation is to be light in color,  and to reflect rather than absorb the Sun's rays. Desert mammals also depart from the normal mammalian practice of maintaining a constant body temperature. Instead of trying to keep down the body temperature deep inside the body, which would involve the expenditure of water and energy,  desert mammals allow their temperatures to rise to what would normally be fever height, and temperatures as high as 46 degrees Celsius have been measured in Grant's gazelles. The overheated body then cools down during the cold desert night, and indeed the temperature may fall unusually low by dawn,  as low as 34 degrees Celsius in the camel. This is an advantage since the heat of the first few hours of daylight is absorbed in warming up the body, and an excessive buildup of heat does not begin until well into the day.

Another strategy of large desert animals is to tolerate the loss of body water to a point that would be fatal for non-adapted animals. The camel can lose up to 30 percent of its body weight as water without harm to itself, whereas human beings die after losing only 12 to 13 percent of their body weight. An equally important adaptation is the ability to replenish this water loss at one drink. Desert animals can drink prodigious volumes in a short time, and camels have been known to imbibe over 100 liters in a few minutes. A very dehydrated person, on the other hand, cannot drink enough water to rehydrate at one session, because the human stomach is not sufficiently big and because a too rapid dilution of the body fluids causes death from water intoxication. The tolerance of water loss is of obvious advantage in the desert, as animals do not have to remain near a water hole but can obtain food from grazing sparse and far-flung pastures. Desert-adapted mammals have the further ability to feed normally when extremely dehydrated, it is a common experience in people that appetite is lost even under conditions of moderate thirst.

No matter how much you’ve trained, performance anxiety before or during a competition may occur, hindering the results of your match. 
While you can tell yourself to stay calm prior to a competition, managing performance anxiety may not be as simple as. Research has shown that strategies such as meditation and guided imagery are great places to start; both require your brain to rehearse what you will do during your competition. Your imagination holds much more power than you may expect, helping you focus on how to beat your opponent, instead of other factors that contribute to your anxiety. Adequate preparation also plays a large role.
To master the mental game, it takes time. Starting one month before your competition, consider sitting in solitude in a comfortable position for 15 minutes each day. Focus first on breathing in and out deeply. Then, begin to imagine competition situations and visualize yourself in a fight with your competitor. Be mindful of your anxiety and return your focus to breathing if you feel yourself tense up. Sometimes, you may find yourself thinking self-deprecating or negative thoughts, at which point you should consciously replace any negative self-talk with positive self-talk. During these visualizations, also be sure to think about your posture and form and create cues — mental and verbal — that will help you review and correct your technique.
Pre-competition jitters are completely normal and it’s important to acknowledge that. Accepting that this excitement and/or nervousness is normal will help your body also understand that what you are experiencing is not fear, but perhaps part of your adrenaline response to competition. With more experience, mindful visualization and mental/physical preparation can help you manage and overcome performance anxiety.

Psychologists have debated a long time about whether a child's upbringing can give it the ability to do outstandingly well. Some think that it is impossible to develop genius and say that it is simply something a person is born with. Others, however, argue that the potential for great achievement can be developed. The truth lies somewhere between these two extremes.
It seems very obvious that being born with the right qualities from gifted parents will increase a child's ability to do well. However, this ability will be fully realized only with the right upbringing and opportunities. As one psychologist says, "To have a fast car, you need both a good engine and fuel.” Scientists have recently assessed intelligence, achievement, and ability in 50 sets of identical twins that were separated shortly after birth and brought up by different pa rents. They found that achievement was based on intelligence, and later influenced by the child's environment
One case involving very intelligent twins was quoted. One of the twins received a normal upbringing, and performed well. The other twin, however, was brought up by extremely supportive parents and given every possible opportunity to develop its abilities. That twin, though starting out with the same degree of intelligence as the other, performed even better.
This case reflects the general principle of intelligence and ability. The more favorable the environment, the more a child's intelligence and ability are developed. However, there is no link between intelligence and the socioeconomic level of a child's family.  In other words, it does not matter how poor or how rich a family is, as this does not affect intelligence.
Gifted people cannot be created by supportive parents, but they can be developed by them.
One professor of music said that outstanding musicians usually started two or three years earlier than ordinary performers, often because their parents had recognized their ability. These musicians then needed at least ten years' hard work and training in order to reach the level they were capable of attaining.
People who want to have very gifted children are given the following advice:
- Marry an intelligent person.
- Permit children to chase their own interests rather than the interests of the parents.
- Start a child's education early but avoid pushing the child too hard.
- Encourage children to play; for example, playing with musical instruments is essential for a child who wants to become an outstanding musician.

   Mandatory volunteering made many members of Maryland's high school class of 97 grumble with indignation. They didn't like a new requirement that made them take part in the school's community service program. Future seniors, however, probably won't be as resistant now that the program has broken in. Some, like John Maloney, already have completed their required hours of approved community service. The Bowie High School sophomore earned his hours in eighth grade by volunteering two nights a week at the Larkin-Chase Nursing and Restorative Center in Bowie.He played shuffle board, cards, and other games with the senior citizens. He also helped plan parties for them and visited their rooms to keep them company.

   John, fifteen, is not finished volunteering. Once a week he videotapes animals at the Prince George's County animal shelter in Forestville. His footage is shown on the Bowie public access television channel in hopes of finding homes for the animals. "Volunteering is better than just sitting around," says John, "and I like animals; I don't want to see them put to sleep." He's not the only volunteer in his family. His sister, Melissa, an eighth grader, has completed her hours also volunteering at Larkin-Chase.

   "It is a good idea to have kids go out into the community, but it's frustrating to have to write essays about the works," she said. It makes you feel like you're doing it for the requirement and not for yourself." The high school's service learning office, run by Beth Ansley, provides information on organizations seeking volunteers so that students will have an easier time fulfilling their hours.

   "It's ridiculous that people are opposing the requirements," said Amy Rouse, who this summer has worked at the Ronald McDonald House and has helped to rebuild a church in Clinton.

   "So many people won't do the service unless it's mandatory," Rouse said, "but once they start doing it, they'll really like it and hopefully it will become a part of their lives - like it has become a part of mine."

In the passage, the author gives the explanation of the concept of mandatory volunteer programs by ______.

The best explainer videos are realized by great background score. When was the last time you watched a silent movie? Never? Not for a while? A long while? Even if you remember watching one, it would still have had a background score, or you’ve accidentally pressed the mute button!
The importance of background music and sound effects for your explainer video, therefore, cannot be overstated. You may not need a full blown orchestra or classy jazz tones to create the mood, but whether going for a subtle effect, a professional demonstration or simply trying to attract customers, music is a must. Explainer videos have the emotional quotient working for them and music is just going to add more to make the viewers relate to the pain points you are highlighting in your video. Imagine if your favorite video game has no background music or sound effects to back the amazing graphics? Would you play it with the same feel and excitement? Nah! Same is the case with your explainer videos. They need to and should have apt sound effects to make them worth your viewer’s time.
While the focus of explainer videos production is more on passing the desired information and explaining technical and complex procedures easily, it doesn’t mean you’ll be distracting your viewers with the background music. The sound effects and music is not going to take the message away from your explainer, it’s just going to enhance it and turn it more watchable and share-able. Even if your video doesn’t require a background score, it must include some sound effects or else it would be not so good an experience for those who choose to watch it

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. 
      To quote CREST founder Dr. Martha Honey, we earnestly believe that ecotourism is “simply a better way to travel.” Here’s a look at how this transformational approach to travel benefits conservation, increases cross-cultural understanding, and ultimately turns travelers into environmental advocates:
       To see how ecotourism benefits nature and wildlife, let’s look at endangered species such as African Elephants. Ivory from Elephant tusks is worth $1500 a pound on the black market, which has led to a dramatic increase in poaching. But Elephants are worth 76 times more alive than dead. When you consider the revenue from wildlife photography tours, luxury safari camps, and other ecotourism offerings, a single Elephant is worth $1.3 million over the course of its lifetime! Ecotourism offers a long-term alternative to exploitation, generating sustainable revenue and ensuring better overall health of the ecosystem.
       Nature reserves and national parks help prevent deforestation and pollution, while also protecting the habitat of endemic species. The revenue that ecotourism provides can help replace profits from exploitative practices such as mining or slash ‘n’ burn agriculture. It can also help ensure the long-term financial viability of the area. Naturalist guides also help travelers understand the value of a pristine ecosystem, and teach them about the importance of conservation. This ultimately help to create a more mindful and conscious legion of travelers.
      When managed properly, ecotourism can offer locals alternative revenue streams. In wildlife-rich countries such as Rwanda, former poachers are often employed as guides or trackers, capitalizing on their knowledge of the animals and their habitat. In Costa Rica, unemployment has fallen to less than 10% since the country started building its ecotourism infrastructure in the 1970s. Involving local communities in tourism management empowers them by ensuring that more revenue is reinvested locally. Ecotourism also offers indigenous peoples an opportunity to remain on ancestral land, conserve it, and preserve traditional culture.
      Sure, being a responsible traveler takes a greater level of commitment to being conscious and mindful of the impact we have on the destinations we visit. But ecotourism also offers us incredible, transformative experiences, allowing us to develop closer personal relationships to the nature, wildlife, and local people we encounter during our adventures. Learning about ecotourism can permanently change your understanding of mankind’s role in our planetary ecosystem. And once you’ve had that sort of travel experience, you’ll never want to travel the traditional way again.

   Thanksgiving is celebrated in the US on the fourth Thursday in November. For many Americans it is the most important holiday apart from Christmas. Schools, offices and most businesses close for Thanksgiving, and many people make the whole weekend a vacation.

   Thanksgiving is associated with the time when Europeans first came to North America. In 1620 the ship the Mayflowers arrived, bringing about 150 people who today are usually called Pilgrims. They arrived at the beginning of a very hard winter and could not find enough to eat, so many of them died. But in the following summer Native Americans showed them what foods were safe to eat, so that they could save food for the next winter. They held a big celebration to thank God and the Native Americans for the fact that they had survived.

   Today people celebrate Thanksgiving to remember these early days. The most important part of the celebration is a traditional dinner with foods that come from North America. The meal includes turkey, sweet potatoes (also called yams) and cranberries, which are made into a kind of sauce or jelly. The turkey is filled with stuffing or dressing, and many families have their own special recipe. Dessert is pumpkin made into a pie.

   On Thanksgiving there are special television programs and sports events. In New York there is the Macy's Thanksgiving Day Parade, when a long line of people wearing fancy costumes march through the streets with large balloons in the shape of imaginary characters. Thanksgiving is considered the beginning of the Christmas period, and the next day many people go out to shop for Christmas presents.

The primary attraction of snorkeling is the opportunity to observe underwater life in a natural setting, such as coral reefs, fish, starfish, and mollusks. Other organisms that can be seen while snorkeling include various forms of seaweed, jellyfish, shrimp and sea turtles. Snorkeling requires no special training, only the ability to swim and to breathe through the snorkel. However, it is considered advisable that one get some instruction from a tour guide, dive shop, or equipment rental shop, any of which often can be found around popular snorkeling locations. Instruction generally covers equipment usage, basic safety, what to look for, and what to look out for, including how not to damage fragile organisms such as coral. As with scuba diving, it is always recommended that one, should not snorkel alone, but rather with a friend, a guide, or a tour group

Swim fins used in snorkeling are usually longer than those used in diving. Snorkel is a tube about thirty centimeters (twelve inches) long, usually J-shaped, fitted with a mouthpiece, and constructed of rubber or plastic. It is used for breathing air from above the water surface when the mouth and nose are submerged, either when snorkeling or during a surface swim before or after scuba diving. The snorkel usually has a piece of rubber that attaches the snorkel to the outside of the strap of the diving mask, as sticking the snorkel in between the strap and the mask could cause the mask to leak, or risk losing the snorkel should the diver choose to switch to scuba.

Typically, the diving mask also serves to prevent breathing through the nose, so that one is forced to breathe through the snorkel. This also provides some negative pressure which helps keep the .mask sealed against the face, though attempting to breathe out through the nose can break this seal and fog the mask.

A snorkeler should not ________.

Large animals that inhabit the desert have evolved a number of adaptations for reducing the effects of extreme heat. One adaptation is to be light in color,  and to reflect rather than absorb the Sun's rays. Desert mammals also depart from the normal mammalian practice of maintaining a constant body temperature. Instead of trying to keep down the body temperature deep inside the body, which would involve the expenditure of water and energy,  desert mammals allow their temperatures to rise to what would normally be fever height, and temperatures as high as 46 degrees Celsius have been measured in Grant's gazelles. The overheated body then cools down during the cold desert night, and indeed the temperature may fall unusually low by dawn,  as low as 34 degrees Celsius in the camel. This is an advantage since the heat of the first few hours of daylight is absorbed in warming up the body, and an excessive buildup of heat does not begin until well into the day.

Another strategy of large desert animals is to tolerate the loss of body water to a point that would be fatal for non-adapted animals. The camel can lose up to 30 percent of its body weight as water without harm to itself, whereas human beings die after losing only 12 to 13 percent of their body weight. An equally important adaptation is the ability to replenish this water loss at one drink. Desert animals can drink prodigious volumes in a short time, and camels have been known to imbibe over 100 liters in a few minutes. A very dehydrated person, on the other hand, cannot drink enough water to rehydrate at one session, because the human stomach is not sufficiently big and because a too rapid dilution of the body fluids causes death from water intoxication. The tolerance of water loss is of obvious advantage in the desert, as animals do not have to remain near a water hole but can obtain food from grazing sparse and far-flung pastures. Desert-adapted mammals have the further ability to feed normally when extremely dehydrated, it is a common experience in people that appetite is lost even under conditions of moderate thirst.

The word "obtain" is closest in meaning to.....................

Today we take electricity for granted and perhaps we do not realize just how useful this discovery has been. Steam was the first invention that replaced wind power. It was used to drive engines and was passed through pipes and radiators to warm rooms. Petrol mixed with air was the next invention that provided power. Exploded in a cylinder, it drove a motor engine, Beyond these simple and direct uses, those forms have not much adaptability.
On the other hand, we make use of electricity in thousands of ways. From the powerful voltages that drive our electric trains to the tiny current needed to work a simple calculator,   and from the huge electric magnet in steel works that can lift 10 tons to the tiny electric magnet in a doorbell, all are powered by electricity. An electric current can be made with equal ease to heat a huge mass of molten metal in a furnace, or to boil a jug for a  cup of coffee. Other than atomic energy, which has not as yet been harnessed to the full, electricity is the greatest power in the world. It is flexible, and so adaptable for any task for which it is wanted. It travels so easily and with incredible speed along wires or conductors that it can be supplied instantly over vast distances.
To generate electricity, huge turbines or generators must be turned. In  Australia they use coal or water to drive this machinery. When dams are built, falling water is used to drive the turbines without polluting the atmosphere with smoke from coal. Atomic power is used in several countries but there is always the fear of an accident. A tragedy once occurred at Chernobyl, in Ukraine, at an atomic power plant used to make electricity. The reactor leaked, which caused many deaths through radiation.
Now scientists are examining new ways of creating electricity without harmful effects to the environment. They may harness the tides as they flow in and out of bays. Most importantly, they hope to trap sunlight more efficiently. We do use solar heaters for swimming pools but as yet improvement in the capacity of the solar cells to create more current is necessary. When this happens, electric cars will be viable and the world will rid itself of the toxic gases given off by trucks and cars that burn fossil fuels.

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. 
      To quote CREST founder Dr. Martha Honey, we earnestly believe that ecotourism is “simply a better way to travel.” Here’s a look at how this transformational approach to travel benefits conservation, increases cross-cultural understanding, and ultimately turns travelers into environmental advocates:
       To see how ecotourism benefits nature and wildlife, let’s look at endangered species such as African Elephants. Ivory from Elephant tusks is worth $1500 a pound on the black market, which has led to a dramatic increase in poaching. But Elephants are worth 76 times more alive than dead. When you consider the revenue from wildlife photography tours, luxury safari camps, and other ecotourism offerings, a single Elephant is worth $1.3 million over the course of its lifetime! Ecotourism offers a long-term alternative to exploitation, generating sustainable revenue and ensuring better overall health of the ecosystem.
       Nature reserves and national parks help prevent deforestation and pollution, while also protecting the habitat of endemic species. The revenue that ecotourism provides can help replace profits from exploitative practices such as mining or slash ‘n’ burn agriculture. It can also help ensure the long-term financial viability of the area. Naturalist guides also help travelers understand the value of a pristine ecosystem, and teach them about the importance of conservation. This ultimately help to create a more mindful and conscious legion of travelers.
      When managed properly, ecotourism can offer locals alternative revenue streams. In wildlife-rich countries such as Rwanda, former poachers are often employed as guides or trackers, capitalizing on their knowledge of the animals and their habitat. In Costa Rica, unemployment has fallen to less than 10% since the country started building its ecotourism infrastructure in the 1970s. Involving local communities in tourism management empowers them by ensuring that more revenue is reinvested locally. Ecotourism also offers indigenous peoples an opportunity to remain on ancestral land, conserve it, and preserve traditional culture.
      Sure, being a responsible traveler takes a greater level of commitment to being conscious and mindful of the impact we have on the destinations we visit. But ecotourism also offers us incredible, transformative experiences, allowing us to develop closer personal relationships to the nature, wildlife, and local people we encounter during our adventures. Learning about ecotourism can permanently change your understanding of mankind’s role in our planetary ecosystem. And once you’ve had that sort of travel experience, you’ll never want to travel the traditional way again.

The most suitable title for the passage could be ______.
