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:
Reading to oneself is a modern activity which was almost unknown to the scholars of the classical and medieval worlds, while during the fifteenth century the term “reading” undoubtedly meant reading aloud. Only during the nineteenth century did silent reading become commonplace.
One should be wary, however, of assuming that silent reading came about simply because reading aloud was a distraction to others. Examinations of factors related to the historical development of silent reading have revealed that it became the usual mode of reading for most adults mainly because the tasks themselves changed in character.
The last century saw a steady gradual increase in literacy and thus in the number of readers. As the number of readers increases, the number of potential listeners decline and thus there was some reduction in the need to read aloud. As reading for the benefit of listeners grew less common, so came the flourishing of reading as a private activity in such public places as libraries, railway carriages and offices, where reading aloud would cause distraction to other readers.
Towards the end of the century, there was still considerable argument over whether books should be used for information or treated respectfully and over whether the reading of materials such as newspapers was in some mentally weakening. Indeed, this argument remains with us still in education. However, whatever its virtues, the old shared literacy culture had gone and was replaced by the printed mass media on the one hand and by books and periodicals for a specialized readership on the other.
By the end of the twentieth century, students were being recommended to adopt attitudes to books and to use reading skills which were inappropriate, if not impossible, for the oral reader.
The social, cultural and technological changes in the century had greatly altered what the term “reading” implied.The writer of this passage is attempting 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:
If you could travel back in time five centuries, you'd encounter a thriving Aztec empire in Central Mexico, a freshly painted "Mona Lisa" in Renaissance Europe and cooler temperatures across the Northern Hemisphere. This was a world in the midst of the Little Ice Age (A.D. 1300 to 1850) and a period of vast European exploration now known as the Age of Discovery. But what if we could look 500 years into the future and glimpse the Earth of the 26th century? Would the world seem as different to us as the 21st century would have seemed to residents of the 16th century? For starters, what will the weather be like?
Depending on whom you ask, the 26th century will either be a little chilly or infernally hot.
Some solar output models suggest that by the 2500s, Earth's climate will have cooled back down to near Little Ice Age conditions. Other studies predict that ongoing climate change and fossil fuel use will render much of the planet too hot for human life by 2300.
Some experts date the beginning of human climate change back to the Industrial Revolution in the 1800s, others to slash-and-burn agricultural practices in prehistoric times. Either way, tool- wielding humans alter their environment -- and our 26th century tools might be quite impressive indeed.
Theoretical physicist and futurist Michio Kaku predicts that in a mere 100 years, humanity will make the leap from a type zero civilization to a type I civilization on the Kardashev Scale. In other words, we'll become a species that can harness the entire sum of a planet's energy. Wielding such power, 26th-century humans will be masters of clean energy technologies such as fusion and solar power. Furthermore, they'll be able to manipulate planetary energy in order to control global climate. Physicist Freeman Dyson, on the other hand, estimates the leap to a type I civilization would occur within roughly 200 years.
Technology has improved exponentially since the 1500s, and this pace will likely continue in the centuries to come. Physicist Stephen Hawking proposes that by the year 2600, this growth would see 10 new theoretical physics papers published every 10 seconds. If Moore's Law holds true and both computer speed and complexity double every 18 months, then some of these studies may be the work of highly intelligent machines.
What other technologies will shape the world of the 26th century? Futurist and author Adrian Berry believes the average human life span will reach 140 years and that the digital storage of human personalities will enable a kind of computerized immortality. Humans will farm the oceans, travel in starships and reside in both lunar and Martian colonies while robots explore the outer cosmos.The word “infernally” 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.
When we think of the renewable energy transition, we often have in mind dark blue photovoltaic rectangles carpeting the landscape or large three-blade horizontal axis wind turbines marching along mountain ridges or into the sea. We think about grid reliability and consumer cost per kilowatt-hour, or we think about the climate change apocalypse that we will impose on future generations if we fail to act swiftly enough. All of these elements are important from technical and policy perspectives, but there is something missing that will be key to success if we are to meet the goals that we have set for ourselves. We must recognize the importance of human culture to the realization of change.
It is a lack of imagination that has brought us to the brink, and it will be an influx of imagination that can possibly pull us back from it. If we are going to succeed in reducing carbon emissions, we must make the solutions more visible, inspire the general public, and get people excited about the renewable energy transition.
This is the mission of the Land Art Generator Initiative (LAGI), a nonprofit that works with cities around the world on civic art installations that also function as renewable energy infrastructures. These generous works of art give back more than just beauty and return more than just kilowatt hours on their capital investment. LAGI design competitions have changed the way that cities and developers manage the integration of public art and creative placemaking into the master planning process for new developments. Competitions for Dubai/Abu Dhabi (2010), New York City (2012), Copenhagen (2014), Glasgow (2015), Santa Monica (2016), Willimantic (2017), and Melbourne (2018) have brought in over 1,000 designs from 60+ countries.Which best serves as the title for 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:
A generation gap in the workplace can make workers both young and old feel inferior, as well as hamper productivity and teamwork. Differences between generations can be seen in work ethics, habits and communication styles. Younger workers might fear not being taken seriously by their older colleagues, while older workers might fear that their experience is not valued but replaced by workers with knowledge of more current technology. However, members of each generation can close the gap between them if they're willing to meet one another halfway.
Older workers can show respect to the younger set by asking for their opinions and recognizing their contributions to the workplace as valid, or complimenting them on a job well done. Younger workers can show their elders respect by asking for advice on how to manage a situation with work, based on the older worker's many years of experience. It's important for both entry- and senior-level workers to see each other as equals, regardless of the type of position in which they work. No one wants to feel inferior or irrelevant just because of their age. Rather, a generation gap at work can be a learning opportunity.
Workers can also put themselves in their colleagues' shoes to determine what might be bothering them about their generational age difference. If a person is much older than another, perhaps it is bitterness about fewer job opportunities, or fear that a younger worker might seem more relevant and edge him out of his job. If workers open their minds to understand where co-workers are coming from, it can help ease any tension between them and appreciate each other's
work contributions.
If age seems to be a problem for someone at the workplace, it can be helpful to do the very opposite of what a co-worker might expect from someone of a different age set due to stereotypes. For example, if a worker is considerably younger such as right out of college, she can share researched information to indicate that she knows what she's doing, or show curiosity instead of upset to indicate emotional maturity if the person makes a disparaging remark about her youth. Older workers can maintain an enthusiastic attitude about work instead of showing boredom or bitterness from past experiences.
Workers can, moreover, directly address the concern of age differences at work with the colleague at odds with them by asking the person for constructive advice on how to handle the issue. For example, older workers who are unfamiliar with new software that younger colleagues understand might acknowledge to them that they did the same tasks differently in years past but show interest in learning the program to keep up with modern technology. Learning to speak their technological language can make them feel more connected. Likewise, a younger worker can admit to being green on the work scene, but eager to gain experience by learning from senior colleagues.Each generation should respect the other generation at work 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:
Franklin D. Roosevelt, the 32nd President of the United States, was from a wealthy well- known family. As a child, he attended private school, had private tutors, and traveled with his parents to Europe. He attended Harvard University, and afterward studied law. At age 39, Roosevelt suddenly developed polio, a disease that left him without the full use of his legs for the rest of his life. Even though the worst of his illness, however, he continued his life in politics. In 1942 he appeared at the Democratic National Convention to nominate Al Smith for president, and eight years after that he himself was nominated for the same office. Roosevelt was elected to the presidency during the Great Depression of the 1930s, at a time when more than 5,000 banks had failed and thousands of people were out of work. Roosevelt took action. First he declared a bank holiday that closed all the banks so no more could fail; then he reopened the banks little by little with government support. Roosevelt believed in using the full power of government to help what he called the “forgotten people”. And it was these workers, the wage earners, who felt the strongest affection toward Roosevelt. There were others, however, who felt that Roosevelt’s policies were destroying the American system of government, and they opposed him in the same intense way that others admired him
In 1940 the Democrats nominated Roosevelt for an unprecedented third term. No president in American history had ever served three terms, but Roosevelt felt an obligation not to quit while the United States’ entry into World War II was looming in the future. He accepted the nomination and went on to an easy victory.aThe word “full” in the first paragraph could be best replaced by which of the following?

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:
Film is an illusion because the moving pictures seen on the screen are not moving at all. A film is actually a series of tiny still pictures, or flames. They appear to be moving because the retina of the human eye retains the impression of an object for a split second after that object has actually disappeared. This principle is known as the persistence of vision. When we look at a single frame of film, the image persists in the brain's visual center for a fraction of a second. Then, the next frame comes along and the brain has to catch up with the new image. Thus, our eyes and brain trick US into thinking that we see a smoothly moving image rather than a series of still ones.
Another illusion of film is known collectively as special effects, the tricks and techniques that filmmakers use when makeup, costume, and stunts are still not enough to make a scene convincing. Special effects artists apply science to filmmaking, showing US things that no plain camera could ever photograph. Even since the introduction of computer graphics in recent decades, the films of today still rely on some special effects that have existed since the early years of cinema.
One category of special effects is called optical or visual effects, tricks made with the camera. One of the pioneers of optical effects was the French filmmaker Georges Méliès, who invented a technique called stop-motion photography. With this technique, a scene is filmed, the camera is stopped, the scene is changed in some way, and then the camera rolls again. Stop motion photography can create the illusion of an actor disappearing on screen. In one short film, an actor's clothes keep returning to his body as he tries to get undressed. Méfiés also invented a technique known as split screen. By putting a card over the camera lens, he prevented half of the frame of film from being exposed. He filmed a scene on the uncovered half of the frame and then backed up the same strip of film in his camera. For the second shot, he covered the exposed half and took another series of pictures on the half that had been covered the first time. With the technique of split screen, it is possible to achieve illusions such as having the same actor play twins.
Mechanical effects are another category of special effects. Mechanical effects are objects or devices used during the filming to create an illusion, such as feathers or plastic chips to simulate snow, and wires to create the illusion that people are flying. Many sound effects are mechanical effects. Wood blocks create a horse's hoof beats, and a vibrating sheet of metal sounds like thunder. During the silent film era, the music machine called the Kinematophone was popular because it could produce the sounds of sirens, sleigh bells, gunfire, baby cries, and kisses-all at the press of a key.
Other mechanical effects are puppets, robots of all sizes, and tiny copies of buildings or cities. To reduce the cost of studio sets or location photography, special-effects technicians create painted or projected backgrounds, which replace the set or add to it. For example, in a long shot of a town, the set might be only a few feet high, and the remainder of the town is painted onto a sheet of glass positioned in front of the camera during filming. In a 1916 silent film called The Flying Torpedo, mechanical effects created the appearance of an enemy invasion of the California seacoast. Technicians threw small contact- rigged explosives into toy cities, scattering the tiny buildings into the air. An artist painted a row of battleships on a board that was only six feet long. Carpenters drilled small holes in the ships, which were filled with small charges of flash powder to simulate guns. An electrician wired the charges so they could be fired on cue from a small battery. For audiences of t -

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:
Dolphins are one of the most intelligent species on the planet, which makes them a very interesting animal to scientists. In their natural habitats, dolphins use various vocalization techniques. They whistle and squeak to recognize members of their pod, identify and protect their young, and call out warnings of danger. They also make clicking sounds used for echolocation to find food and obstacles in dark and murky waters.
Amazingly, the whistling sound that the bottlenose dolphin makes has been found to have a similar pattern to human language. They always make conversational sounds when they greet each other. If you listen to dolphins' squeaks and squeals, it will sound like they are having a conversation.
Dolphins usually use both sound and body language to communicate with each other. It is through gesture and body language, however, that most of their communication with humans comes. Dolphins can be trained to perform complicated tricks. This suggests they have a high level of intelligence and communication capacity. If they work for a long time with a trainer, they are able to recognize and understand human commands.
A lot of dolphin communication has been studied using dolphins in captive environments. These studies have been criticized because some marine biologists believe that dolphins living in aquariums or research centers cannot be considered "normal." Even so, most believe that studying dolphin communication in captivity is useful for beginning to understand the complexity of dolphin communication. After all, dolphins are one of the most intelligent animals. Their ability to communicate is impressive and worthy of study.It can be inferred from what the write said in the last paragraph that .

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.

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 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.Which of the following best expresses the essential information in the bold sentence in paragraph 3?

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:
How is the news different from entertainment? Most people would answer that news is real but entertainment is fiction. However, if we think more carefully about the news, it becomes clear that the news is not always real. The news does not show us all the events of the day, but stories from a small number of chosen events. The creation of news stories is subject to specific constraints, much like the creation of works of fiction. There are many constraints, but three of the most important ones are: commercialism, story formulas, and sources.
Newspapers, radio, and TV stations are businesses, all of which are rivals for audiences and advertising revenue. The amount of time that the average TV station spends on news broadcasts has grown steadily over the last fifty years - largely because news is relatively cheap to produce, yet sells plenty of advertising. Some news broadcasts are themselves becoming advertisements. For example, during one week in 1996 when the American CBS network was airing a movie about the sinking of the Titanic, CBS news ran nine stories about that event (which had happened 84 years before). The ABC network is owned by Disney Studios, and frequently runs news stories about Mickey Mouse. Furthermore, the profit motive drives news organizations to pay more attention to stories likely to generate a large audience, and to shy away from stories that may be important but dull. This pressure to be entertaining has produced shorter, simpler stories: more focus on celebrities than people of substance, more focus on gossip than on news, and more focus on dramatic events than on nuanced issues.
As busy people under relentless pressure to produce, journalists cannot spend days agonizing over the best way to present stories. Instead, they depend upon certain story formulas, which they can reuse again and again. One example is known as the inverted pyramid. In this formula, the journalist puts the most important information at the beginning of the story, than adds the next most important, and so on. The inverted pyramid originates from the age of the telegraph, the idea being that if the line went dead halfway through the story, the journalist would know that the most crucial information had at least been relayed. Modern journalists still value the formula for a similar reason. Their editors will cut stories if they are too long. Another formula involves reducing a complicated story into a simple conflict. The best example is "horse race" election coverage. Thorough explication of the issues and the candidates' views is forbiddingly complex. Journalists therefore concentrate more on who is winning in the opinion polls, and whether the underdog can catch up in the numbers than on politicians' campaign goals.
Sources are another constraint on what journalists cover and how they cover it. The dominant sources for news are public information officers in businesses and government offices. The majority of such officers try to establish themselves as experts who are qualified to feed information to journalists. How do journalists know who is an expert? In general, they don't. They use sources not on the basis of actual expertise, but on the appearance of expertise and the willingness to share it. All the major news organizations use some of the same sources (many of them anonymous), so the same types of stories always receive attention. Over time, the journalists may even become close friends with their sources, and they stop searching for alternative points of view. The result tends to be narrow, homogenized coverage of the same kind.The word "them" in paragraph 4 refers to _.

Astronomers have for the first time definitively ID’d the birth of a specific heavy element during a neutron-star smashup. They found strontium. And it showed up in the wavelengths of light — or spectra — making up this collision’s afterglow.
Scientists had assumed that a collision by two super-dense objects, such as neutron stars, would trigger a chain of nuclear reactions. They’re known as the r-process. In such an environment, the nuclei of atoms could rapidly gobble up neutrons. Afterward, those nuclei would become transformed in a process known as radioactive decay. The r-process was seen as a way to transform old, smaller elements into newer, bigger ones. About half of all elements heavier than iron were thought to be made in the r-process. Finding strontium in the recent collision at last offered the most direct evidence yet that neutron-star collisions really do trigger the r-process.
Physicists had long predicted that silver, gold and many other elements more massive than iron formed this way. But scientists weren’t sure where those r-process reactions took place. After all, no one had directly seen the r-process underway in a celestial event. Or they didn’t until the merger of two neutron stars in 2017. Scientists quickly analyzed light given off by that cataclysm. In it, they found evidence of the birth of a hodgepodge of heavy elements. All would seem to have come from the r-process.
The researchers were examining mostly very heavy elements — ones whose complex atomic structures can generate millions of spectral features. And all of those features were not yet fully known, Watson points out. This made it extremely difficult to tease apart which elements were present, he says.
Strontium, however, is relatively light compared to other r-process elements. And its simple atomic structure creates a few strong and well-known spectral clues. So Watson and his colleagues expanded their analysis to consider it. In doing so, they turned up the clear "fingerprint" of strontium. It emerged in light collected by the Very Large Telescope in Chile within a few days of the neutron-star collision. Seeing strontium in the afterglow wasn’t all that unexpected, says Brian Metzger. He’s an astrophysicist at Columbia University in New York City and not involved in the new work. Strontium, he notes, “does tell us something interesting” about the elements formed during the neutron-star collision.According to paragraph 5, why did the researchers extend the reviewed scale of elements for strontium?

Most people start smoking when they are in their teens and are addicted by the time they reach adulthood. Some have tried to quit but have returned to cigarettes because smoking is such a strong addiction. It is a habit that is very difficult to break. There are many different reasons why people smoke.
Three of the main reasons that young people smoke are to look mature, to be like their friends, and to experiment. Since teens see older people all around them smoking, especially their parents and relatives, they smoke to act older. If their friends or peers smoke, they may feel pressured into doing the same to be accepted. The last reason is the excitement of experimenting with something that is forbidden. In Massachusetts it is against the law for anyone under 18 years old to smoke. Usually parents do not allow their under age teens to smoke. Therefore, smoking becomes very attractive. It is exciting to get cigarettes and sneak away to smoke without being caught.
Adults smoke for other reasons. They may have a lot of stress and pressures because of economic and personal problems. They may be unemployed or working but not making enough money to take care of themselves and their families. They may be homeless, or they may be dealing with alcohol or cocaine/heroin addictions. Some may be in bad marriages or relationships in which there is physical and/or verbal abuse. All these people may smoke to feel relaxed or to give them energy while going through a hard time.
Whether young or old, some people smoke to control their weight. Smokers, on the average, weigh seven pounds less than non-smokers. Smoking reduces a person's appetite. It lessens his/her sense of taste and smell. This could be why ex-smokers gain weight after quitting cigarettes. Food tastes and smells so much better.
Finally, there are people who say they love to smoke. Smoking gives them pleasure. It just makes them feel good.he main purpose of paragraph 4 is .

A tropical cyclone is a violent low pressure storm that usually occurs over warm oceans of over 80°F or 27°C. It winds counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as it is described for the term, cyclone itself. This powerful storm is fueled by the heat energy that is released when water vapor condenses at high altitudes, the heat ultimately derived from the Sun.
The center of a tropical cyclone, called the eye, is relatively calm and warm. This eye, which is roughly 20 to 30 miles wide, is clear, mainly because of subsiding air within it. The ring of clouds around the eye is the eyewall, where clouds reach highest and precipitation is heaviest. The strong wind, gusting up to 360 kilometers per hour, occurs when a tropical cyclone’s eyewall passes over land.
There are various names for a tropical cyclone depending on its location and strength. In Asia, a tropical cyclone is named according to its strength. The strongest is a typhoon; its winds move at more than 117 kilometers per hour. In India, it is called a cyclone. Over the North Atlantic and in the South Pacific, they call it a hurricane.
On average, there are about 100 tropical cyclones worldwide each year. A tropical cyclone peaks in late summer when the difference between temperature in the air and sea surface is the greatest. However, it has its own seasonal patterns. May is the least active month, while September is the most active.
The destruction associated with a tropical cyclone results not only from the force of the wind, but also from the storm surge and the waves it generates. It is born and sustained over large bodies of warm water, and loses its strength over inland regions that are comparatively safe from receiving strong winds. Although the tract of a tropical cyclone is very erratic, the Weather Service can still issue timely warnings to the public if a tropical cyclone is approaching densely populated areas. If people ever experience a cyclone, they would know how strong it could be.What can be inferred about typhoons, cyclones and hurricanes?

Setting up and running a car company was an expensive business and required a lot of workers. A company that makes its money out of a smart app requires less capital, doesn't have to pay (81) storage or transport in the way that car companies do and (82) virtually no extra costs as the number of users increases.
In the jargon of economics, the marginal costs per unit of output tend towards zero and the returns to scale are high. This explains why tech entrepreneurs can get very rich very young. Technological change has always been (83) There was a polarization of income and wealth in the first wave of industrialization at the beginning of the 19th century, and this gave rise to political and institutional change over the 100 years between 1850 and 1950: the spread of democracy; the emergence of trade unions; progressive taxation and the development of social safety nets. These helped create bigger markets for the consumer goods that were spawned by the second Industrial Revolution: TVs, radios, vacuum cleaners and the like. (84) over the past four decades a political model that both facilitated the spread of technology and provided some protection against its disruptive consequences has come under attack. Welfare states have become less generous, levels of long-term unemployment are much higher, taxation has become less progressive, and politics has increasingly been dominated by those with the deepest pockets (85) can lobby the loudest.(84)..............

Transportation accounts for up to one–third of greenhouse gas emissions from the world’s biggest cities and traffic is the largest source of toxic air pollution. To create sustainable, healthy and liveable cities, we need to increase the number of cyclists on our streets, and that means getting more women on their bikes. In San Francisco, only 29% of cyclists are women; in Barcelona, there are three male cyclists for every female cyclist; in London, 37% of cyclists are female.
Surveys reveal that potential cyclists of all genders are deterred by similar concerns, including aggressive and speeding drivers, the threat posed by large vehicles such as lorries and buses, and bike theft. However, women disproportionately view protected cycle lanes as a more urgent priority.
According to research about women and cycling in San Francisco, cities should invest in protected cycle lanes with consistent and clear signage that function as a joined–up network to encourage female riders. Together with more secure cycle parking, these infrastructure investments would make cycling safer, supporting those who already cycle and encouraging those who do not yet ride.
People do what they perceive to be possible. Research in San Francisco found that women, especially women of colour, felt that “people like me” do not cycle. Similarly, 49% of people in London say they do not feel cycling is for “people like them”. More diverse and inclusive imagery of cyclists (in policy documents, in the media and on city streets) could help challenge these perceptions and make more people feel that cycling is for everyone. Social events that enable women to try cycling in a relaxed environment, perhaps as part of a buddy or mentor system that pairs experienced cyclists with those newer to cycling, can help make cycling more accessible and inclusive, along with approaches such as female–led maintenance classes.
The different decisions men and women make about cycling are not only based on issues of convenience or comfort. People’s perceptions of safety influence how, when, where and why they travel. Women and girls learn early on to worry about their personal safety when out and about, and to change their behaviour, dress, speech and travel patterns to avoid sexual harassment or violence. Cities must take women’s and girls’ safety considerations seriously through initiatives such as safety audits.The word “deterred” in paragraph 2 mostly means .

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 antsThe word “excavate” is closest in meaning to
