Scientists have uncovered a new threat to the world's endangered coral reefs. They have found that most are incapable of growing quickly enough to compensate for rising sea levels triggered by global warming. The study suggests that reefs - which are already suffering serious degradation because the world's seas are warming and becoming more acidic - could also become overwhelmed by rising oceans.
The research - led by scientists at Exeter University and published in Nature this week - involved studying growth rates for more than 200  tropical western Atlantic and  Indian Ocean  reefs. It was found only 9% of these reefs had the ability to keep up  with even the most optimistic rates of sea-level rises forecast by the Intergovernmental Panel on Climate Change. "For many   reefs across the Caribbean and Indian Ocean regions, where the study focused, rates of growth are slowing due to coral reef degradation," said Professor Chris Perry, of Exeter University. “Meanwhile, rates of sea-level rise are increasing - and our results suggest reefs will be unable to  keep up. As a result, water depths above most reefs will increase rapidly through this century.”
Sea levels rose by  several inches over the past century and measurements indicate the speed of this increase is now rising significantly. Two key factors are involved: climate change is making  ocean water warmer and so it expands. And as ice sheets and glaciers melt, they increase amounts of water in the oceans.
At the same time, reefs are being weakened by ocean warming and also by ocean acidification, triggered as the seas absorb more and more carbon dioxide. These effects lead to bleaching events that kill off vast stretches of coral and limits their ability to grow.
“Our predictions, even under the best case scenarios, suggest that by  2100, the inundation  of reefs will expose coastal communities to significant threats of shoreline change,” said co-author Prof Peter Mumby of Queensland University. This point was backed by US marine scientist Ilsa Ruffner writing in a separate comment piece for Nature. “The implications of the study are dire. Many island nations and territories are set to quickly lose crucial natural resources.”

What does the word "compensate" in the first paragraph probably mean?

The culture of Vietnam is one of the oldest in Southeast Asia, with the ancient Bronze age Đông Sơn culture being widely considered one of its most important progenitors. In spite of geographically Southeast Asian, Vietnamese culture was heavily influenced by Chinese culture in terms of politics, government, social and moral ethics, and art due to 1000 years of Chinese rule. Thus, Vietnam is considered to be part of the East Asian cultural sphere together with China, Japan, Korea and Taiwan.

Following independence from China in the 10th century, Vietnam began a southward expansion that saw the annexation of territories formerly belonging to the Champa Civilization (now Central Vietnam) and parts of the Khmer Empire (now Southern Vietnam). Gradually, there are minor regional variances in Vietnam's culture due to exposure to these different groups.

During the French colonial period, Vietnamese culture absorbed various influences from the Europeans, including the spread of Catholicism and the adoption of the Latin alphabet. Prior to this, Vietnamese had used both Chinese characters and a script called Chữ Nôm which was based on Chinese but included newly invented characters to represent native Vietnamese words.

In the socialist era, the cultural life of Vietnam has been deeply influenced by government-controlled media and the cultural influences of socialist programs. For many decades, foreign cultural influences from the Western World were shunned, and emphasis was placed on sharing the culture of communist nations such as those in the Soviet Union, Cuba, China, and others.

Some elements generally considered to be characteristic of Vietnamese culture include ancestor veneration, respect for community and family values, handicrafts and manual labour, and devotion to study. Important symbols present in Vietnamese culture include dragons, turtles, lotuses, and bamboo.

Which reason led to the minor regional variances in Vietnam's culture?

The Atmosphere of Venus
Venus, also called the Morning Star and Evening Star, is the second-closest planet to the sun and the brightest object in the night sky. The planet orbits the sun every two hundred and twenty four Earth-days and is sometimes referred to as Earth’s sister planet because the two share both a similar size and bulk. What is not similar, however, is Venus’s atmosphere in comparison to Earth’s atmosphere.
The atmosphere on Venus is much heavier and has a higher density than that of Earth. Venus’s atmosphere also expands significantly higher than Earth’s atmosphere although a thick cloud cover makes the surface of Venus nearly impossible to see unless observed through radar mapping.
While the pressure and temperature of Venus’s upper atmosphere are comparable to those of Earth, the heat and pressure of the lower atmosphere are not unlike a furnace. Venus’s atmosphere is very thick due to a composition consisting mainly of carbon dioxide, and a small amount of nitrogen. If man could survive the extreme heat of Venus’s surface (400 degrees Celsius), then he would have to contend with a surface pressure that is more than 90 times that of Earth. Venus’s extremely high temperature is thanks to the greenhouse effect caused by such a large amount of carbon dioxide. The greenhouse effect is a process by which the sun’s infrared radiation is more readily absorbed by the atmosphere. Just like in a real greenhouse used to grow plants years round, the proliferation of carbon dioxide traps radiation and warms Venus’s atmosphere. Due to this phenomenon, Venus boasts a higher atmospheric temperature than Mercury, even though Venus is twice the distance from the sun.
However, scientists postulate that Venus’s atmosphere was not always so hot. Studies show that large bodies of water were once on Venus’s surface but that eventually evaporation of all the water caused the runaway greenhouse effect which regulates the planet today.Thus Venus has become a critical study for today’s scientists, as human being are only beginning to struggle with the early stages of the greenhouse effect. Our problems do not stem from evaporated water supplies but from a propagation of carbon dioxide and other greenhouse gases due to industrial and automobile emissions.
Another interesting characteristic to note regarding Venus’s atmosphere is that its daytime temperatures and nighttime temperatures are not that far removed from each other. This is due to the thermal inertia, the ability of a substance to store heat despite changing temperatures and the transfer of heat by Venus’s strong winds. Although winds on the surface of Venus move slowly in comparison with Earth’s winds, Venus’s air is so dense that a slow-moving there can move large obstructions and even skip stones along the planet’s surface.
In 1966, humankind made its first attempt at sending a recording instrument into Venus’s atmosphere. The Venera 3 probe did collide with Venus surface; however, the abrupt impact caused its communication system to fail, and it was unable to send and feedback. In 1967, Venera 4 successfully enter Venus’s atmosphere and was able to take many readings, one of which recorded that Venus’s atmosphere was between ninety and ninety-five percent carbon dioxide. Subsequent Venera probes were sent into Venus’s atmosphere, but most of them succumbed to the crushing air pressure.

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

Do you think you're smarter than your parents and grandparents? According to James Flynn, a professor at a New Zealand university, you are! Over the course of the last century, people who have taken IQ tests have gotten increasingly better scores-on average, three points better for every decade that has passed. This improvement is known as "the Flynn effect," and scientists want to know what is behind it.
IQ tests and other similar tests are designed to measure general intelligence rather than knowledge. Flynn knew that intelligence is partly inherited from our parents and partly the result of our environment and experiences, but the improvement in test scores was happening too quickly to be explained by heredity. So what was happening in the 20th century that was helping people achieve higher scores on intelligence tests?
Scientists have proposed several explanations for the Flynn effect. Some suggest that the improved test scores simply reflect an increased exposure to tests in general. Because we take so many tests, we learn test-taking techniques that help us perform better on any test. Others have pointed to better nutrition since it results in babies being born larger, healthier, and with more brain development than in the past. Another possible explanation is a change in educational styles, with teachers encouraging children to learn by discovering things for themselves rather than just memorizing information. This could prepare people to do the kind of problem solving that intelligence tests require.
Flynn limited the possible explanations when he looked carefully at the test data and discovered that the improvement in scores was only on certain parts of the IQ test. Test takers didn't do better on the arithmetic or vocabulary sections of the test; they did better on sections that required a special kind of reasoning and problem solving. For example, one part of the test shows a set of abstract shapes, and test-takers must look for patterns and connections between them and decide which shape should be added to the set.
According to Flynn, this visual intelligence improves as the amount of technology in our lives increases. Every time you play a computer game or figure out how to program a new cell phone, you are exercising exactly the kind of thinking and problem solving that helps you do well on one kind of intelligence test. So are you really smarter than your parents? In one very specific way, you may be.a

Which statement would Professor Flynn agree with?

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

All of the following were mentioned in the passage as alphabet systems that Squoyah borrowed from EXCEPT    .

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Very few people in the modem world obtain their food supply by hunting and gathering in the natural environment surrounding their homes. This method of harvesting from nature’s provision is the oldest known subsistence strategy and has been practised for at least the last two million years. It was, indeed, the only way to obtain food until rudimentary farming and the domestication of wild animals were introduced about 10,000 years ago.
Because hunter-gatherers have fared poorly in comparison with their agricultural cousins, their numbers have dwindled, and they have been forced to live in marginal environments, such as deserts and arctic wastelands. In higher latitudes, the shorter growing seasons have restricted the availability of plant life. Such conditions have caused a greater dependence on hunting, and on fishing along the coasts and waterways. The abundance of vegetation in the lower latitudes of the tropics, on the other hand, has provided a greater opportunity for gathering a variety of plants. In short, the environmental differences have restricted the diet and have limited possibilities for the development of subsistence societies.
Contemporary hunter-gatherers may help US understand our prehistoric ancestors. We know from the observation of modem hunter-gatherers in both Africa and Alaska that a society based on hunting and gathering must be very mobile. While the entire community camps in a central location, a smaller party harvests the food within a reasonable distance from the camp. When the food in the area has become exhausted, the community moves on to exploit another site. We also notice seasonal migration patterns evolving for most hunter-gatherers, along with a strict division of labor between the sexes. These patterns of behavior may be similar to those practised by mankind during the Paleolithic Period.

A typical feature of both modem and prehistoric hunter-gatherers is that    .

Baseball evolved from a number of different ball-and stick games (paddle ball, trap ball, one-old- cat, rounders, and town ball) originating in England. As early as the American Revolution, it was noted that troops played “baseball” in their free time. In 1845 Alexander Cartwright formalized the New York Knickerbockers’ version of the game: a diamond shaped infield, with bases ninety feet apart, three strikers - you’re - out, batter out on a caught ball, three outs per inning, a nine-man team. “The New York Game” spread rapidly, replacing earlier localized forms. From its beginnings, baseball was seen as a way of satisfying the recreational needs of an increasingly urban - industrial society. At its inception it was it was played by and for gentlemen. A club might consist of 40 members. The president would appoint two captains who would choose teams from among the members. Games were played on Monday and Thursday afternoons, with the losers often providing a lavish evening’s entertainments for the winners.
During the 1850 - 70 period the game was changing, however, with increasing commercialism (charging admission), under - the - table payments to exceptional players, and gambling on the outcome of games. By 1868 it was said that a club would have their regular professional ten, an amateur first - nine, and their “muffins” (the gentlemanly duffers who once ran the game). Beginning with the first openly all - salaried team (Cincinnati’s Red Stocking Club) in 1869, the 1870- 1890 period saw the complete professionalization of baseball, including formation of the National Association of Professional baseball players in 1871. The National League of Professional Baseball Clubs was formed in 1876, run by business-minded invertors in joint-stock company clubs. The 1880s has been called Major League Baseball’s “Golden Age”. Profits soared, player’s salaries rose somewhat, a season of 84 games became one of 132, a weekly periodical “The sporting News” came into being, wooden stadiums with double- deck stands replaced open fields, and the standard refreshment became hot dogs, soda pop and peanuts. In 1900 the Western League based in the growing cities of the Mis west proclaimed itself the American League.

Sharks have gained an unfair reputation for being fierce predators of large sea animals. Humanity's unfounded fear and hatred of these ancient creatures is leading to a worldwide slaughter that may result in the extinction of many coastal shark species. The shark is the victim of a warped attitude of wildlife protection; we strive only to protect the beautiful, non-threatening parts of our environment. And, in our efforts to restore only non-threatening parts of our earth, we ignore other important parts.
A perfect illustration of this attitude is the contrasting attitude toward another large sea animal, the dolphin. During the 1980s, environmentalists in the United States protested the use of driftnets for tuna fishing in the Pacific Ocean since these nets also caught dolphins. The environmentalists generated enough political and economic pressure to prevent tuna companies from buying tuna that had been caught in driftnets. In contrast to this effort on behalf of the dolphins, these same environmentalists have done very little to help save the Pacific Ocean sharks whose population has decreased nearly to the point of extinction.
Sharks are among the oldest creatures on earth, having survived in the seas for more than 350 million years. They are extremely efficient animals, feeding on wounded or dying animals, thus performing an important role in nature of weeding out the weaker animals in a species. Just the fact that species such as the Great White Shark have managed to live in the oceans for so many millions of years is enough proof of their efficiency and adaptability to changing environments. It is time for US humans, who may not survive another 1,000 years at the rate we are damaging the planet, to cast away our fears and begin considering the protection of sharks as an important part of a program for protection of all our natural environment.

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions:
The blue whale is the largest animal ever known to  have existed. During the 20th century,  the species was almost exterminated due to commercial whaling. The species has slowly recovered following the global whaling ban but it remains endangered and faces a  number of  serious threats including ship strikes and the impact of climate change.
Blue whales are simply enormous with most ranging in length from 24-30 m. The largest  ever recorded was a gargantuan 33.5 m long. Females are up to 10 m longer than males. And they can weigh up to 200 tonnes. Just to put that in perspective: an adult male African elephant weighs 6 tonnes. The blue whale's heart is the size of a small car and its beat can be detected two miles away. But that's nothing compared to their calls. Blue whales are the loudest animals on earth and their calls are louder than a jet engine: reaching 188 decibels, while a jet's engine hit 'just' 140 decibels. Apart from their gigantic size, blue whales can be identified by their relatively small dorsal fin, a fairly rounded rostrum (anterior part of the skull), and approximately 90 ventral  grooves, which reach the navel. They also have row of 300-400 baleen plates on each side of the mouth, which are black in color and range in length from 50 cm in front to 100 cm in back.
Blue whales mostly travel alone or in groups of 2-3. Larger groups of up to 60 whales have been reported and are probably associated with feeding grounds. However, the blue whale has the most powerful voice in the animal kingdom and its low-frequency sounds can travel in deep water over hundreds, or even thousands, of miles. Under these circumstances, animals which may appear to us to be traveling alone may actually be in constant contact with one another.
At birth, a blue whale calf is the largest baby on earth: approximately 8m long and weighing about 4 tonnes. They grow at a rate of 90 kg per day and wean after 7-8 months, once they have reached about 15 m in length, and are able to follow the normal migration pattern alone. They reach sexual maturity at 5-10 years. This growth rate is astonishing and is probably the fastest in the animal kingdom.  From  conception to weaning, it represents a several billion-fold increase in tissue in just over a year and a half. Like other baleen whales, the blue whale has no teeth so it is hard to tell its age but scientists believe they live until at least 50.
Like other large whales, blue whales are threatened by chemical and sound pollution, habitat loss, overfishing of krill, ship strikes and becoming entangled in fishing gear. Climate change could also have a major impact on its food supply, since global warming and associated ocean acidification may impact krill populations. In addition, frontal zones - critical whale habitats - are projected to move further south due to climate change. Frontal zones are boundaries between different water masses, where water can rise from the depths, bringing with it large amounts of nutrients that stimulate the growth of phytoplankton and support substantial populations of prey species for whales. Blue whales would have to migrate further (perhaps 200-500 km more) to reach and feed at these food-rich areas where they build up reserves to sustain themselves for the rest of the year. These longer migration paths could increase the energy costs  of migration and reduce the duration of the main feeding season. As frontal zones move southward, they also move closer together, reducing the overall area of foraging habitat available.

According to the last paragraph, how does climate change affect the blue whale?

These helped create bigger markets for the consumer goods that were spawned by the second Industrial Revolution: TVs, radios, vacuum cleaners and the like.

Newspapers and television news programs always seem to report about the bad things happening in society. However, there is a place where readers can find some good news. That place is the website called HappyNews. The man behind HappyNews is Byron Reese. Reese set up HappyNews because he thought other news sources were giving people an unbalanced view of the world. Reese said about HappyNews, “The news media gives you a distorted view of the world by exaggerating bad news, misery, and despair. We’re trying to balance out the scale.”
Not everyone agrees with Reese’s view, though. Many people think that news sources have a responsibility to provide news that is helpful to people. People need to know about issues or problems in today’s society. Then they are better able to make informed decisions about things that affect their daily lives. Reese said that HappyNews is not trying to stop people from learning about issues or problems. HappyNews is just trying to provide a balanced picture of today’s world.
