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.
There are already many, many people who have passed the landmark age of 100. In fact, there are now so many healthy, elderly people that there's a new term for them: the wellderly. These are people over the age of 80 who have no diseases such as high blood pressure, heart disease or diabetes and have never taken medicines for these conditions.
There have been many scientific studies of communities where a healthy old age is typical. These include places like Calabria in southern Italy and the island of Okinawa in Japan.
The small village of Molochio in Calabria has about 2,000 inhabitants. And of these there are at least eight centenarians. When researchers ask people like this the secret of their long life, the answer is almost always to do with diet and is almost always the same: 'I eat a lot of fruit and vegetables.' 'A little bit, but of everything.’ ‘No smoking, no drinking.’
While in the past scientists have looked at things such as diet and lifestyle for an explanation of long life, these days they are investigating genetics. One such researcher is Eric Topol, who says, "There must be genes that explain why these individuals are protected from the aging process."
The new research into long life looks at groups of people who have a genetic connection. For example, one group of interest lives in Ecuador. In one area of the country there are a number of people with the same genetic condition. It's called Laron syndrome. The condition means that they don't grow to more than about one, but it also seems to give them protection against cancer and diabetes. As a result, they live longer than other people in their families. Meanwhile, on the Hawaiian island of Oahu, there's another group of long-lived men, Japanese-Americans. They have a similar gene to the Laron syndrome group.
Back in Calabria, scientists are trying to work out exactly how much of the longevity is due to genetics and how much to environment. By checking public records going back to the 19th century, researchers have reconstructed the family trees of 202 nonagenarians and centenarians. They concluded that there were genetic factors involved.Healthy elderly people ______________________.

It is hard to get any agreement on the precise meaning of the term "social class". In everyday life, people tend to have a different approach to those they consider their equals from which they assume with people they consider higher or lower than themselves in social scale. The criteria we use to 'place' a new acquaintance, however, are a complex mixture of factors. Dress, way of speaking, area of residence in a given city or province, education and manners all play a part.
In ancient civilizations, the Sumerian, for example, which flourished in the lower Euphrates valley from 2000 to 5000 B.C. social differences were based on birth, status or rank, rather than on wealth. Four main classes were recognized. These were the rulers, the priestly administrators, the freemen (such as craftsmen, merchants or farmers) and the slaves.
In Greece, after the sixth-century B.C., there was a growing conflict between the peasants and the aristocrats, and a gradual decrease in the power of the aristocracy when a kind of ‘middle class’ of traders and skilled workers grew up. The population of Athens, for example, was
divided into three main classes which were politically and legally distinct. About one-third of the total population was slaves, who did not count politically at all, a fact often forgotten by those who praise Athens as the nursery of democracy. The next main group consisted of resident foreigners, the, ‘metics’ who were freemen, though they too were allowed no share in political life. The third group was the powerful body of ‘citizens”, who were themselves divided into sub- classes.
In the later Middle Ages, however, the development of a money economy and the growth of cities and trade led to the rise of another class, the ‘burghers’ or city merchants and mayors. These were the predecessors of the modern middle classes. Gradually high office and occupation assumed importance in determining social position, as it became more and more possible for a person born to one station in life to move to another. This change affected the towns more than the country areas, where remnants of feudalism lasted much longer.According to the passage, we evaluate other people's social position by ...........

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:
Peru’s Inca Indians first grew potatoes in the Andes Mountains in about 200 BC. Spanish conquistadors brought potatoes to Europe, and colonists brought them to America. Potatoes are fourth on the list of the world’s food staples – after wheat, corn, and rice. Today, Americans consume about 140 pounds of potatoes per person every year, while Europeans eat twice as many.
One of our favourite ways to eat potatoes is in the form of potato chips. While Benjamin Franklin was the American ambassador to France, he went to a banquet where potatoes were prepared in 20 different ways. Thomas Jefferson, who succeeded Franklin as our French ambassador, brought the recipe for thick–cut, French fried potatoes to America. He served French fries to guests at the White House in 1802 and at his home, Monticello.
A native American chef named George Crum created the first potato chips on August 24, 1853, at Moon Lake Lodge in Saratoga, New York. He became angry when a diner complained that his French fries were too thick, so he sliced the potatoes as thinly as possible, making them too thin and crisp to eat with a fork. The diner loved them, and potato chips were born. In 1860, Chef Crum opened his own restaurant and offered a basket of potato chips on every table.
Joe “Spud” Murphy and Seamus Burke produced the world’s first seasoned crisps, cheese & onion and salt & vinegar chips, in the 1950s in Ireland. In the United Kingdom and Ireland, crisps are what we, in the United States, call potato chips, while their chips refer to our French fries. Ketchup–flavored chips are popular in the Middle East and Canada. Seaweed–flavored chips are popular in Asia, and chicken– flavored chips are popular in Mexico. Other flavors from around the world include: paprika, pickled onions, béarnaise, meat pie, chili crab, salmon teriyaki, borscht, Caesar salad, roasted sausage, firecracker lobster, roast ox, haggis and black pepper, olive, and spaghetti.Which of the following is a true statement?

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.
Different cultures follow their own special customs when a child's baby teeth fall out. In Korea, for example, they have the custom of throwing lost teeth up on the roof of a house. According to tradition, a magpie will come and take the tooth. Later, the magpie will return with a new tooth for the child. In other Asian countries, such as Japan and Vietnam, children follow a similar tradition of throwing their lost teeth onto the roofs of houses.
Birds aren't the only animals thought to take lost teeth. In Mexico and Spain, tradition says a mouse takes a lost tooth and leaves some money. However, in Mongolia, dogs are responsible for taking teeth away. Dogs are highly respected in Mongolian culture and are considered guardian angels of the people. Tradition says that the new tooth will grow good and strong if the baby tooth is fed to a guardian angel. Accordingly, parents in Mongolia will put their child's lost tooth in a piece of meat and feed it to a dog.
The idea of giving lost teeth to an angel or fairy is also a tradition in the West. Many children in Western countries count on the Tooth Fairy to leave money or presents in exchange for a tooth. The exact origins of the Tooth Fairy are a mystery, although the story probably began in England or Ireland centuries ago. According to tradition, a child puts a lost tooth under his or her pillow before going to bed. In the wee hours, while the child is sleeping, the Tooth Fairy takes the tooth and leaves something else under the pillow. In France, the Tooth Fairy leaves a small gift. In the United States, however, the Tooth Fairy usually leaves money. These days, the rate is $1 to $5 per tooth, adding up to a lot of money from the Tooth Fairy!

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:
Certainly no creature in the sea is odder than the common sea cucumber. All living creature, especially human beings, have their peculiarities, but everything about the little sea cucumber seems unusual. What else can be said about a bizarre animal that, among other eccentricities, eats mud, feeds almost continuously day and night but can live without eating for long periods, and can be poisonous but is considered supremely edible by gourmets?
For some fifty million years, despite all its eccentricities, the sea cucumber has subsisted on its diet of mud. It is adaptable enough to live attached to rocks by its tube feet, under rocks in shallow water, or on the surface of mud flats. Common in cool water on both Atlantic and Pacific shores, it has the ability to suck up mud or sand and digest whatever nutrients are present.
Sea cucumbers come in a variety of colors, ranging from black to reddish – brown to sand – color and nearly white. One form even has vivid purple tentacles. Usually the creatures are cucumber – shaped – hence their name – and because they are typically rock inhabitants, this shape, combined with flexibility, enables them to squeeze into crevices where they are safe from predators and ocean currents.
Although they have voracious appetites, eating day and night, sea cucumbers have the capacity to become quiescent and live at a low metabolic rate-feeding sparingly or not at all for long periods so that the marine organisms that provide their food have a chance to multiply. If it were not for this faculty, they would devour all the food available in a short time and would probably starve themselves out of existence.
But the most spectacular thing about the sea cucumber is the way it defends itself. It major enemies are fish and crabs, when attacked; it squirts all its internal organs into the water. It also casts off attached structures such as tentacles. The sea cucumber will eviscerate and regenerate itself if it is attacked or even touched; it will do the same if surrounding water temperature is too high or if the water becomes too polluted.Which of the following would NOT cause a sea cucumber to release its internal organs into the water?

People in the UK enjoy fewer years of good health before they die than the citizens of most comparable European countries as well as Australia and Canada, a major report shows. While life expectancy has improved by 4.2 years in the UK over the two decades, other countries have improved faster. In 2010, Spain topped the league. Its people could expect 70.9 years of healthy life - before disease and disability began to take a toll. Second came Italy, with 70.2 years and third was Australia, on 70.1 years. In the UK, we can expect 68.6 healthy years of life.
Hunt said the UK was a long way behind its global counterparts and called for action by local health commissioners to tackle the five big killers - cancer, heart disease, stroke, respiratory and liver diseases. Drinking and drug use have been the main issues behind the worsening of the UK's ranking in early deaths among adults aged 20-54. In 2010, drugs were the sixth leading cause of death in this age group and alcohol was 18th - up from 32nd and 43rd place respectively 20 years earlier.
Hunt will on Tuesday announce a strategy to tackle cardiovascular disease, which he says could save 30,000 lives a year. "Despite real progress in cutting deaths, we remain a poor relative to our global cousins on many measures of health, something I want to change," he said. "For too long we have been lagging behind and I want the reformed health system to take up this challenge and turn this shocking underperformance around.” However, the problem is only in part to do with hospital care - much of it is about the way we live. Our diet, our drinking and continuing smoking habits all play a part, which assumes its responsibilities on 1 April.The word “it” in paragraph 2 refers to ?

American movies create myths about college life in the United States. These stories are entertaining, but they are not true. You have to look beyond Hollywood movies to understand what college is really like.
Thanks to the movies, many people believe that college students party and socialize more than they study. Movies almost never show students working hard in class or in the library. Instead, movies show them eating, talking, hanging out, or dancing to loud music at wild parties. While it is true that American students have the freedom to participate in activities, they also have academic responsibilities. In order to succeed, they have to attend classes and study hard.
Another movie myth is that athletics is the only important extracurricular activity. In fact, there is a wide variety of nonacademic activities on campus such as special clubs, service organizations, art, and theater programs. This variety allows students to choose what interests them. Even more important, after graduation, students’ résumés look better to employers if they list a few extracurricular activities.
Most students in the movies can easily afford higher education. If only this were true! While it is true that some American college students are wealthy, most are from families with moderate incomes. Up to 80% of them get some type of financial aid. Students from middle and lower- income families often work part-time throughout their college years. There is one thing that many college students have in common, but it is not something you will see in the movies. They have parents who think higher education is a priority, a necessary and important part of their children's lives.
Movies about college life usually have characters that are extreme in some way: super athletic, super intelligent, super wealthy, super glamorous, etc. Movies use these stereotypes, along with other myths of romance and adventure because audiences like going to movies that include these elements. Of course, real college students are not like movie characters at all.
So the next time you want a taste of the college experience, do not go to the movies. Look at some college websites or brochures instead. Take a walk around your local college campus. Visit a few classes. True, you may not be able to see the same people or exciting action you will see in the movies, but you can be sure that there are plenty of academic adventures going on all around you!Which of the following is NOT mentioned in 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:
Tides are the periodic rise and fall of the Earth’s waters that are caused by the Moon’s and Sun’s forces of gravity acting on the Earth .It is important to distinguish natural tidal phenomena from huge tsunamis , with the latter being caused by earthquakes and undersea volcanic eruptions.
The Moon is a main factor controlling ordinary tides. At the location on the Earth closest to the Moon, it exerts a powerful gravitational pull on the water. The resulting rise in the water produces higher tides. The water on the side of the Earth farthest away from the Moon also gets pulled by this lunar gravity, but not as strongly. The Earth itself has its own gravitational force that is constantly pulling waters downward, which is why the oceans do not simply bulge out toward the Moon. Ordinary tides usually feature high and low waters alternating in relation to the Earth’s rotation. Most shores around the world have high waters and two low waters for each day, which last about 24 hours and 50 minutes. The difference in height between the high water and low water is called the range of tide, and it can be quite dramatic in narrower bays
.Canada’s bays of Fundy , for example , commonly experiences the world’s most extreme tidal ranges , with daily differences of the 16 meters.
Two other types of tides are influenced by the Sun, which is much farther away from the Earth and exerts less than half of the Moon’s gravitational force. When the Sun, the Moon and the Earth are directly in line, the solar and lunar gravitational forces add up to produce higher spring tides. The range of spring tides is intensified, with higher water marks and lower low water marks. However, when the Moon is in the first or third quarter, it is at a 90–degree angle with the Sun in relation to the Earth .The opposing solar and lunar forces partially cancel each other out, and the result is a lower tide. This is called a neap tide, which comes twice a month and has lower high water marks and higher low water marks. The range of neap tides is minimum.
Some tides do not occur over water at all. The solid body of the Earth has slight elasticity, so lunar and solar gravity cause it to stretch very subtly. These changes in the Earth’s shape, although imperceptible to humans, are known as Earth tides.
Another tidal phenomenon, atmospheric tides, is caused by the Sun’s heating of the Earth’s atmosphere. Like ordinary tides, they usually occur over 12–hour periods.Why does the author mention tsunamis in the passage?

The great debate, “Is cheerleading a sport?” It’s the topic that will get any cheerleader fired up and ready to defend their side. The definition of sport from the Oxford Dictionary is “An activity involving physical exertion and skill in which an individual or team competes against another or others for entertainment.” Cheer has a competitive nature and it takes both mental and physical ability to succeed. Hollywood has made the “cheerleading character” into a fantasy where all the boys are after them, they’re dumb and they parade around in short skirts. Of course you should never trust the appearance of movies because it’s Hollywood and not reality.
First off, cheerleading has a purpose. The purpose is to encourage positivity and entertain at athletic games and events. Without cheerleaders the “circle of energy” in a game would be non-existent. It’s a sporting event tradition that has lasted for over 100 years.
Also cheerleaders do train for what they do. Just as a football player would, cheerleaders train too. How else do you think the girls get thrown in the air and come down safely? Cheerleaders have to lift weights and do cardio just as any other athlete would. Stunting is the most exciting, entertaining, and dangerous part of cheerleading. Most injuries from cheer end up being concussions, broken bones, stitches, and not to mention the endless bruises. It ranks 1st in the catastrophic sports injuries for women and 2nd in all sports combined next to football.
I believe every sport should have support from others because the athletes care and are passionate about what they do. Cheerleading has its challenges and rewards like every other sport and I believe it’s time for cheerleaders to be recognized for their hard work.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.

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.
Volunteering has been acknowledged as part of the wider health policy, with the NHS five-year plan identifying a need to encourage community volunteering. It also has an important role to play in tackling social exclusion, through projects such as lunch clubs for older people, assisted gardening schemes, or young play leaders.
Volunteering can help to provide people with ways out of poverty, by giving them new skills, confidence and aid social integration. This is of particular value to those who are most excluded from the labour market, such as recent migrants or people with disabilities. But while the benefits of volunteering are clear, there is worrying evidence that the people who could benefit most from giving their time are precisely those least likely to be involved.
There are many reasons for people not to volunteer. For older people, the barriers can include poor health, poverty, lack of skills, poor transport links, or having caring responsibilities, such as looking after grandchildren. Younger people can be deterred by feeling they don’t have the time to volunteer, or not knowing anyone else who volunteers. Many of them also think volunteering is just for older people with time on their hands. Volunteering has an image problem – particularly with men and younger people.
More should be done to promote the value of volunteering to the particular needs of different groups. There is evidence on why people choose to volunteer, and we need to make better use of that information. For instance, a recent survey showed that 95% of young people, aged 13-24, hoped to develop new skills through volunteering, compared to just 32% of volunteers aged over 55. Almost three quarters of young people were keen to gain qualifications through volunteering compared to just 13% of those over 55. Over three quarters of disabled volunteers were keen to develop new skills and nearly two thirds hoped to improve their health and wellbeing through volunteering.What does the phrase “many of them” in paragraph 3 refer to?

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:
Robots are useful for exploring and working in space. In particular, many robots have been sent to explore Mars. Such robots have usually looked like a box with wheels. Though these robots are useful, by their very nature they are unreliable, extremely expensive, and they break easily. Also, they cannot do very many tasks. Because of these problems, scientists have been developing a new and unusual kind of robot. These new robots move like snakes, so they have been given the name "snakebots."
The way a snake is shaped lets it get into very small spaces, like cracks in rocks. It can also push its way below the ground or climb up different kinds of objects, like high rocks and trees. Such abilities account for the usefulness of a robot designed like a snake. A snakebot would be able to do these things, too, making it much more effective than regular robots with wheels, which easily get stuck or fall over. Since they can carry tools, snakebots would be able to work in space, as well. They could, for example, help repair the International Space Station.
But how can such a robot shape be made? A snakebot is built like a Chain made of about thirty parts, or modules. Each module is basically the same in that they all have a small computer and a wheel to aid movement. The large computer in the "head” of the snake makes all of the modules in a snakebot work together.
The modular design of the snakebot has many advantages. If one module fails, another can be added easily. Snakebot modules can also carry different kinds of tools, as well as cameras. Since each module is actually a robot in itself, one module can work apart from the rest if necessary. That is, all the modules can separate and move on their own, and then later, reconnect back into a larger robot.
Researchers are also trying to develop snakebots made of a special kind of plastic that can change its shape using electricity, almost like animal muscles. Snakebots made with this plastic will be very strong and hard to break.
Overall, the snakebot design is much simpler than that of common robots. Thus, snakebots will be much less expensive to build. For example, a robot recently sent to Mars cost over a hundred million dollars, whereas snakebots can cost as little as a few hundred dollars. With their versatility and affordability, snakebots seem to be the wave of the future, at least as far as space robots are concerned.According to the passage, which of the following is TRUE about the snakebots?

Have you ever thought about inventing something? Did you worry that your idea was too strange or unrealistic? Well, maybe you should think again. Strange or unrealistic ideas never stopped Arthur Pedrick. Pedrick was a British inventor. Originally a government clerk, he spent his retirement in the 1960s and 1970s developing new and unusual ideas. Some of these ideas contradicted basic physics, but that didn’t stop Pedrick. One of his strangest ideas was a plan to connect large tubes from the continent of Australia all the way to Antarctica, a distance of 10,000 km! These tubes would carry giant ice balls from Antarctica to Australia. This ice would then melt in the Australian desert, and the water would be used in irrigation. Another of Pedrick’s inventions was a radio-controlled golf ball. A golfer could change the speed and direction of the golf ball by small flaps, controlled by computer chips. Using radio waves, the golfer could also find lost golf balls. Arthur Pedrick had thousands of bizarre ideas for inventions, most of which were never built.
Though many of Pedrick’s inventions were never developed, a lot of other strange ideas were. In 1989, a company designed and sold a theft-prevention device for expensive cars. As part of this device, several tubes were attached to the bottom of a car. If someone tried to steal the car, super hot flames would come out of the tubes and burn the car thief. Some people who were not thieves, however, were seriously injured. They accidentally set off the device by walking past the car. Other strange inventions include underwear for dogs and pens with drinkable ink. The underwear keeps dogs from making a mess when they go out for a walk. Also, if you are ever thirsty during a test, a pen with drinkable ink would be very handy! If you have an idea that seems a little out in left field, don’t let that stop you from trying it. You’ll be in good company.The words “out in left field” in paragraph 2 is closest in meaning to .

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.
Optimists have plenty to be happy about. In other words, if you can convince yourself that things will get better, the odds of it happening will improve - because you keep on playing the game. In this light, optimism “is a habitual way of explaining your setbacks to yourself”, reports Martin Seligman, the psychology professor and author of Learned Optimism. The research shows that when times get tough, optimists do better than pessimists - they succeed better at work, respond better to stress, suffer fewer depressive episodes, and achieve more personal goals.
Studies also show that belief can help with the financial pinch. Chad Wallens, a social forecaster at the Henley Centre who surveyed middle-class Britons’ beliefs about income, has found that “the people who feel wealthiest, and those who feel poorest, actually have almost the same amount of money at their disposal. Their attitudes and behaviour patterns, however, are different from one another.”
Optimists have something else to be cheerful about - in general, they are more robust. For example, a study of 660 volunteers by the Yale University psychologist Dr. Becca Levy found that thinking positively adds an average of seven years to your life. Other American research claims to have identified a physical mechanism behind this. A Harvard Medical School study of 670 men found that the optimists have significantly better lung function. The lead author, Dr. Rosalind Wright, believes that attitude somehow strengthens the immune system. “Preliminary studies on heart patients suggest that, by changing a per¬son’s outlook, you can improve their mortality risk,” she says.
Few studies have tried to ascertain the proportion of optimists in the world. But a 1995 nationwide survey conducted by the American magazine Adweek found that about half the population counted themselves as optimists, with women slightly more apt than men (53 per cent versus 48 per cent) to see the sunny side.As mentioned in the passage, who found that optimists have a longer life expectancy than negative counterparts?

People in the UK enjoy fewer years of good health before they die than the citizens of most comparable European countries as well as Australia and Canada, a major report shows. While life expectancy has improved by 4.2 years in the UK over the two decades, other countries have improved faster. In 2010, Spain topped the league. Its people could expect 70.9 years of healthy life - before disease and disability began to take a toll. Second came Italy, with 70.2 years and third was Australia, on 70.1 years. In the UK, we can expect 68.6 healthy years of life.
Hunt said the UK was a long way behind its global counterparts and called for action by local health commissioners to tackle the five big killers - cancer, heart disease, stroke, respiratory and liver diseases. Drinking and drug use have been the main issues behind the worsening of the UK's ranking in early deaths among adults aged 20-54. In 2010, drugs were the sixth leading cause of death in this age group and alcohol was 18th - up from 32nd and 43rd place respectively 20 years earlier.
Hunt will on Tuesday announce a strategy to tackle cardiovascular disease, which he says could save 30,000 lives a year. "Despite real progress in cutting deaths, we remain a poor relative to our global cousins on many measures of health, something I want to change," he said. "For too long we have been lagging behind and I want the reformed health system to take up this challenge and turn this shocking underperformance around.” However, the problem is only in part to do with hospital care - much of it is about the way we live. Our diet, our drinking and continuing smoking habits all play a part, which assumes its responsibilities on 1 April.The word “cardiovascular” in paragraph 2 could be best replaced by .

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:
Atomic were once thought to be fundamental pieces of matter, but they are in turn made of smaller subatomic particles There are three major subatomic particles neutrons, protons, and electronic. Protons and neutrons can be broken into even smaller units, but these smaller units not occur naturally in nature and are thought to only be produced in manmade particle accelerators and perhaps in extreme stellar events like supernovas. The structure of an atom can best be described as a small solar system, with the neutrons at the center and the electrons circling them in various orbits, just as the planets circle the sun. In reality, the structure of an atom is far more complex, because the laws of physics are fundamentally different at the atomic level than at the level of the observable word. The true nature of atomic structure can only be expressed accurately through complex mathematical formulas. This explanation, however, is of little use to most average people.
Protons and neutrons have nearly equal mass and size, but protons carry a positive electrical charge, while neutrons carry no charge at all. Protons and neutrons are bound together by the strong nuclear force, one of the four basic forces in the universe. Protons and neutrons give atoms some of their most basic properties. Elements are defined by two numbers: their atomic number, which is equal to the number of protons they have, and their atomic weight, which is equal to total number of their neutrons and protons. In most lighter atoms, the number of neutrons and protons is equal, and the element is stable. In heavier atoms, however, there are more neutrons than protons, and the element is unstable, eventually losing neutrons through radioactive decay until a neutral state is reached.
Electrons are negatively charged particles. They are bound to their atoms through electromagnetic attraction. Opposite electrical charges attract one another, so the positive charge of the proton helps to keep the negatively charged electron in orbit around the nucleus of the atom. Electrons are different from neutrons in that they cannot be broken down into smaller particles. They are also far smaller and lighter than neutrons and protons. An electron is about one thousandth of the diameter of a proton and an even smaller fraction of its mass. Electrons circle the protons and neutrons at the center of the atom in orbits. These orbits are often called electron shells. The closer the orbit is to the center of the atom, the lower its energy is. There are seven electron shells, and each higher level can hold more electrons than the previous shell. Electrons naturally seek to occupy the lowest shell possible. So, if there is space in a lower shell, an electron will drop down to occupy that space. At temperatures higher than a few hundred degrees, electrons will gain energy and move to a higher shell, but only momentarily. When the electrons drop back down to their natural shell, they emit light. This is why fires and other very hot objects seem to glow.
Electrons are also primarily responsible for many of the chemical properties of atoms. Since electrons seek to occupy the lowest electron shell possible, they will move from one atom to another if there is a space available in a lower electron shell. For example, if there is an atom with an open space in its third shell, and it comes into contact with an atom with electrons in its fourth shell, the first atom will take one of these electrons to complete its third shell. When this happens, the two atoms will be chemically bonded to form a molecule. Furthermore, atoms sometimes lose electrons in collisions with other atoms. When this happens, the radio of protons and electrons in the atom changes, and therefore, the overall electrical charge of the atom changes as well. These atoms -
Ambient divers are, unlike divers who go underwater in submersible vehicles of pressure resistant suits, exposed to the pressure and temperature of the surrounding ambient water. Of all types of diving, the oldest and simplest is free diving. Free divers may use no equipment at all, but most use a face mask, foot fins, and a snorkel. Under the surface, free divers must hold their breath. Most free divers can only descend 30 to 40 feet, but some skilled divers can go as deep as 100 feet.
Scuba diving provides greater range than free diving. The word scuba stands for self-contained underwater breathing apparatus. Scuba divers wear metal tanks with compressed air or other breathing gases. When using open-circuit equipment, a scuba diver simply breathes air form the tank through a hose and releases the exhaled air into the water. A closed-circuit breathing device, also called a rebreather, filters out carbon dioxide and other harmful gases and automatically adds oxygen. This enables the diver to breathe the same air over and over. In surface-supplied diving, divers wear helmets and waterproof canvas suits. Today, sophiticated plastic helmets have replaced the heavy copper helmets used in the past.These divers get their air from a hose connected to compressors on a boat. Surface-supplied divers can go deeper than any other type of ambient diver.When using closed-circuit devices, divers .............

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:
Since the world became industrialized, the number of animal species that have either become extinct or near extinction has increased. Bengal tigers, for instance, which once roamed the jungles in vast numbers, now number only about 2,300. By the year 2025, it is estimated that they will become extinct.
What is alarming about the case of the Bengal tiger is that this extinction will have been caused almost entirely by poachers who, according to some sources, are not always interested in material gain but in personal gratification. This is an example of the callousness that is contributing to the problem of extinction. Animals such as the Bengal tiger, as well as other endangered species, are valuable parts of the world/s ecosystem. International laws protecting animals must be enacted to ensure their survival-and the survival of our planet.
Countries around the world have begun to deal with the problem in various ways. Some countries, in an effort to circumvent the problem, have allocated large amounts of land to animal reserves. They then charge admission prices to help defray the costs of maintaining the parks, and they often must also depend on world organizations for support. This money enables them to invest in equipment and patrols o protect the animals. Another response to the increase in animal extinction is an international boycott of products made from endangered species. This has had some effect, but by itself will not prevent animals from being hunted and killed.aWhich of the following could best replace the word 'case' as used in paragraph 2?
