The diary and the letter were the most extensively practiced forms of life writings in eighteenth- century America. From the numerous examples of these two types of writing from the period, a portrait of daily life of the period can be gleaned.
Many of the diaries that were kept during this period were life diaries by authors interested in maintaining day-to-day records of reflective self-examination, but some of the most compelling were situational diaries; those prompted by and limited to lengthy descriptions of personal reflections about a particular event. Three of the many situational journals of this period are those written by Sarah Kemble Knight, William Burd II, and Dr. Alexander Hamilton. Sarah Kemble Knight's diary of her five-month trip at the end of 1704 and the beginning of 1705 from Boston to New Haven to New York and back again to Boston was published more than a century later as The Journal of Madam Knight. Though this diary does include an account of the hardship that she encountered along the way, it is principally composed of humorous descriptions of and commentary on the hospitality that she was offered and the manners of those that she encountered. William Burd II kept two diaries to describe his experiences on a 1729 surveying expedition to settle a border dispute between Virginia and North Carolina. One of the diaries, History of the Dividing Line between Virginia and North Carolina, was published in 1842, while its companion, Secret Diary, was published in 1929. In these diaries, Burd used a humorous and satirical approach to describe not just the day-to-day events of the trip but also the characteristics which set his beloved Virginia culture apart from the (in his opinion) decidedly less praiseworthy culture of those non- Virginians that he encountered in his trip. Dr. Alexander Hamilton's Itinerarium (1744) describes a four- month voyage of discovery undertaken by Hamilton through the mid-Atlantic and New England colonies; in the diary that he kept of this trip. Hamilton provides considerable commentary on the social customs of various areas, comparing the customs and culture of the better homes of the American colonies with those of the great salons of Europe.
Letter-writing also held a place of importance in eighteenth-century America (indeed, the ability to produce cultured letters was considered a form of art), and many letters extant from that period provide insights into the culture, mores, and styles of written communication of that era. Many of the letter writers employed devices in common usage in European models of the time, demonstrating that letter writers felt a sense of cohesiveness with the cultured classes of Europe: John and Abigail Adams signed the names Lysander and Constantia to their early letters, while Thomas Jefferson created an elaborate dialogue between his head and his heart to discuss the nature of friendship in  a 1786 letter to Maria Cosway. The variety of purposes that these letters served provides additional insight into the priorities of the society of the time. The letters were used to cement love matches and friendships, as the previously mentioned letters did; they were the primary method for relaying news among family and friends who were scattered across various geographic locations; they were often used as a means of carrying out business in this era before more rapid long-distance communication; they were often used used as a way of sharing professional, social, or political ideas among leaders in various fields who perhaps had no other way to get together and exchange ideas.

A number of factors related to the voice reveal the personality of the speaker. The first is the broad area of communication, which includes imparting information by use of language, communicating with a group or an individual and specialized communication through performance. Aperson conveys thoughts and ideas through choice of words, by a tone of voice that is pleasant or unpleasant, gentle or harsh, by the rhythm that is inherent within the language itself, and by speech rhythms that are flowing and regular or uneven and hesitant, and finally, by the pitch and melody of the utterance. When speaking before a group, a person’s tone may indicate uncertainty or fright, confidence or calm. At interpersonal levels, the tone may reflect ideas and feelings over and above the words chosen, or may believe them.Here the participant’s tone can consciously or unconsciously reflect intuitive sympathy or antipathy, lack of concern or interest, fatigue, anxiety, enthusiasm or excitement, all of which are usually discernible by the acute listener. Public performance is a manner of communication that is highly specialized with its own techniques for obtaining effects by voice and /or gesture. The motivation derived from the text, and in the case of singing, the music, in combination with the performer’s skills, personality, and ability to create empathy will determine the success of artistic, political, or pedagogic communication. Second, the voice gives psychological clues to a person’s self-image, perception of others, and emotional health. Self- image can be indicated by a tone of voice that is confident, pretentious, shy, aggressive, outgoing, or exuberant, to name only a few personality traits. Also the sound may give a clue to the facade or mask of that person, for example, a shy person hiding behind an overconfident front. How a speaker perceives the listener’s receptiveness, interest, or sympathy in any given conversation can drastically alter the tone of presentation, by encouraging or discouraging the speaker. Emotional health is evidenced in the voice by free and melodic sounds of the happy, by constricted and harsh sound of the angry, and by dull and lethargic qualities of the depressed.

Why does the author mention “artistic, political, or pedagogic communication”?

The concept of obtaining fresh water from iceberg that is towed to populated areas and arid regions of the world was once treated as a joke more appropriate to cartoons than real life. But now it is being considered quite seriously by many nations, especially since scientists have warned that the human race will outgrow its fresh water supply faster than it runs out of food. Glaciers are a possible source of fresh water that has been overlooked until recently. (A)
Three-quarters of the Earth's fresh water supply is still tied up in glacial ice, a reservoir of untapped fresh water so immense that it could sustain all the rivers of the world for 1,000 years. Floating on the oceans every year are 7,659 trillion metric tons of ice encased in 10,000 icebergs that break away from the polar ice caps, more than ninety percent of them from Antarctica. (B)
Huge glaciers that stretch over the shallow continental shelf give birth to icebergs throughout the year. Icebergs are not like sea ice, which is formed when the sea itself freezes; rather, they are formed entirely on land, breaking off when glaciers spread over the sea. As they drift away from the polar region, icebergs sometimes move mysteriously in a direction opposite to the wind, pulled by subsurface  currents. Because they melt more slowly than smaller pieces of ice, icebergs have been known to drift as far north as 35 degrees south of the equator in the Atlantic Ocean. (C)
The difficulty arises in other technical matters, such as the prevention of rapid melting in warmer climates and the funneling of fresh water to shore in great volume. But even if the icebergs lost half of their volume in towing, the water they could provide would be far cheaper than that produced by desalination, or removing salt from water. (D)

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:
In the twentieth - century, people depend on unlimited energy to power their everyday lives. A wide range of energy-run devices and modern conveniences are taken for granted, and although it may seem that we will never be in danger of living without those conveniences, the fact is that many supplies of energy are dwindling rapidly. Scientists are constantly searching for new sources of power to keep modern society running. Whether future populations will continue to enjoy the benefits of abundant energy will depend on the success of this search.
Coal, oil, and natural gas supply modern civilization with most of its power. However, not only are supplies of these fuels limited, but they are a major source of pollution. If the energy demands of the future are to be met without seriously harming the environment, existing alternative energy sources must be improved or further explored and developed. These include nuclear, water, solar, wind, and geothermal power, as well as energy from new, nonpolluting types of fuels. Each of these alternatives, however, has advantages and disadvantages.
Nuclear power plants efficiently produce large amounts of electricity without polluting the atmosphere; however, they are costly to build and maintain, and they pose the daunting problem of what to do with nuclear waste. Hydroelectric power is inexpensive and environmentally safe, but impractical for communities located far from moving water. Harnessing energy from tides and waves has similar drawbacks. Solar power holds great promise for the future but methods of collecting and concentrating sunlight are as yet inefficient, as are methods of harnessing wind power.
Every source of energy has its disadvantages. One way to minimize them is to use less energy. Conservation efforts coupled with renewable energy resources, such as a combination of solar, water, wind, and geothermal energy and alternative fuels, such as alcohol and hydrogen, will ensure supplies of clean, affordable energy for humanity's future.

Environmental pollution is one of the impacts of human activities on the Earth. Pollution occurs when pollutants contaminate the natural surroundings; which brings about changes that affect our normal lifestyles adversely. Pollution disturbs our ecosystem and the balance in the environment. Pollution occurs in different forms; air, water, soil, radioactive, noise, heat/ thermal and light Let us discuss the causes and effects of air pollution on mankind and the environment as a whole.
Air pollution is the most prominent and dangerous form of pollution. It occurs due to many reasons. Excessive burning of fuel which is a necessity of our daily lives for cooking, driving and other industrial activities; releases a huge amount of chemical substances in the air every day; these pollute the air. Smoke from chimneys, factories, vehicles or burning of wood basically occurs due to coal burning; this releases sulphur dioxide into the air making it toxic.
The effects of air pollution are evident too. The increase in the amount of CO2 in the atmosphere leads to smog which can restrict sunlight from reaching the earth. Thus, preventing plants in the process of photosynthesis. Gases like sulfur dioxide (SO2) and nitrogen oxide (NO) can cause acid rain.
The decrease in quality of air leads to several respiratory problems including asthma or lung cancer. Chest pain, congestion, throat inflammation, cardiovascular disease, respiratory disease are some of diseases that can be caused by air pollution.
The emission of greenhouse gases particularly CO2 is leading to global warming. Every other day new industries are being set up, new vehicles come on roads and trees are cut to make way for new homes. All of them, in direct or indirect way lead to increase in CO2 in the environment. The increase in CO2 leads to melting of polar ice caps which increases the sea level and pose danger for the people living near coastal areas.
Ozone layer is the thin shield high up in the sky that stops ultra violet rays from reaching the  earth. As a result of human activities, chemicals, such as chlorofluorocarbons (CFCs), were released into the atmosphere which contributed to the depletion of ozone layer.

The main difference between urban growth in Europe and in the American colonies was the slow evolution of cities in the former and their rapid growth in the latter. In Europe they grew over a period of centuries from town economies to their present urban structure. In North America, they started as wilderness communities and developed to mature urbanism’s in little more than a century.
In the early colonial day in North America, small cities sprang up along the Atlantic Coastline, mostly in what are now New America, small cities sprang up along the Atlantic United States and in the lower Saint Lawrence valley in Canada. This was natural because these areas were nearest England and France, particularly England, from which most capital goods (assets such as equipment) and many consumer goods were imported Merchandising establishments were, accordingly, advantageously located in port cities from which goods could be readily distributed to interior settlements. Here, too, were the favored locations for processing raw materials prior to export. Boston, Philadelphia, New York, Montreal, and other cities flourished, and, as the colonies grew, these cities increased in importance.
This was less true in the colonial South, where life centered around large farms, known as plantations, rather than around towns, as was the case in the areas further north along the Atlantic coastline. The local isolation and the economic self-sufficiency of the plantations were antagonistic to the development of the towns. The plantations maintained their independence because they were located on navigable streams and each had a wharf accessible to the small shipping of that day. In fact, one of the strongest factors in the selection of plantation land was the desire to have it front on a water highway.
When the United States became an independent nation in 1776, it did not have a single city as large as 50,000 inhabitants, but by 1820 it had a city of more than 10,000 people, and by 1880 it had recorded a city of over one million. It was not until after 1823, after the mechanization of the spinning and weaving industries, that cities started drawing young people away from farms. Such migration was particularly rapid following the Civil War (1861-1865).

According to the passage, early colonial cities were established along the Atlantic coastline of North America due 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:
Many of the most damaging and life-threating types of weather-torrential rains, severe thunderstorms, and tornadoes-begin quickly, strike suddenly, and dissipate rapidly, devastating small regions while leaving neighboring areas untouched. One such event, a tornado, struck the northeastern section of Edmonton, Alberta, in July 1987. Total damages from the tornado exceeded $250 million, the highest ever for any Canadian storm. Conventional computer models of the atmosphere have limited value in predicting short-live local storms like the Edmonton tornado, because the available weather data are generally not detailed enough to allow computers to discern the subtle atmospheric changes that precede these storms. In most nations, for example, weather balloon observations are taken just once every twelve hours at locations typically separated by hundreds of miles. With such limited data, conventional forecasting models do a much better job predicting general weather conditions over large regions than they do forecasting specific local events.
Until recently, the observation-intensive approach needed for accurate, very short range forecasts, or “Nowcasts”, was not feasible. The cost of equipping and operating many thousands of conventional weather stations was prohibitively high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a network were insurmountable. Fortunately, scientific and technological advances have overcome most of these problems. Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observation over large regions at a relatively low cost. Communications satellites can transmit data around the world cheaply and instantaneously, and modern computers can quickly compile and analyzing this large volume of weather information. Meteorologists and computer scientists now work together to design computer programs and video equipment capable of transforming raw weather data into words, symbols, and vivid graphic displays that forecasters can interpret easily and quickly. As meteorologists have begun using these new technologies in weather forecasting offices, Nowcasting is becoming a reality.

Which of the following would best illustrate Nowcasting?

Do you feel like your teenager is spending most of the day glued to a phone screen? You're not too far off. A new survey from the Pew  Research Center reveals the  surprising  ways that technology intersects with teen friendships —  and the results show that 57  percent  of teens have made at least one new friend online. Even more surprisingly, only 20 percent of those digital friends ever meet in person.
While teens do connect with their friends face-to-face outside of school, they spend 55 percent of their day texting with friends, and only 25 percent of teens are spending actual time with their friends on a daily basis (outside of school hallways). These new forms of communication are key in maintaining friendships day-to-day — 27 percent of teens instant message their friends every day, 23 percent connect through social media every day, and 7 percent even video chat daily. Text messaging remains the main form of communication — almost half of survey respondents say it's their chosen method of communication with their closest friend.
While girls are more likely to text with their close friends, boys are meeting new friends (and maintaining friendships) in the gaming world-89 percent play with friends they know, and  54 percent play with online-only friends. Whether they're close with their teammates or not, online garners say that playing makes them feel "more connected" to friends they know, or garners they've never met.
When making new friends, social media has also become a major part of the teenage identity-62 percent of teens are quick to share their social media usernames when connecting with a new friend (although 80 percent still consider their phone number the best method of contact). Despite the negative consequences-21 percent of teenage users feel worse about their  lives because of posts they see on social media — teens also have found  support  and  connection through various platforms. In fact, 68  percent of  teens received support during a challenging time  in their lives via social media platforms.
Just as technology has become a gateway for new friendships, or a channel to  stay  connected with current friends, it can also make a friendship breakup more public. The study reveals that girls are more likely to block or unfriend former allies, and 68 percent of all teenage  users report experiencing "drama among their friends on social media."

By adopting a few simple techniques, parents who read to their children can considerably increase their children’s language development. It is surprising, but true. How parents talk to their children makes a big difference in the children’s language development. If a parent encourages the child to actively respond to what the parent is reading, the child’s language skills increase.
A study was done with two or three-year-old children and their parents. Half of the thirty children participants were in the experimental study; the other half acted as the control group. In the experimental group, the parents were given a two-hour training session in which they were taught to ask open-ended questions rather than yes-no questions. For example, the parent should ask, “What is the doggy doing?” rather than, “Is the doggy running away?” Experimental parents were also instructed how to expand on their children’s answer, how to suggest alternative possibilities, and how to praise correct answers.
At the beginning of the study, the children did not differ on levels of language development, but at the end of one month, the children in the experimental group were 5.5 months ahead of the control group on a test of verbal expression and vocabulary. Nine months later, the children in the experimental group still showed an advance of 6 months over the children in the control group.

Instagram was founded by Kevin Systrom and Mike Krieger in October 2010. Systrom and Krieger initially wanted to create an application for mobile photography called Burbn, but upon developing their idea further, they found that it was too similar to the existing search-result app called Foursquare. They tweaked their original idea until they came up with a photo-sharing app. The name “Instagram” is a combination of “instant camera” and “telegram.”

From the outset, Instagram proved extremely popular. Only two months after its launch, it achieved a million users and reached ten million users in its first year. The simple idea of sharing photos in a social media setting appealed to a wide variety of phone users. As time went on, Systrom and Krieger began making a series of technology-related improvements to the app —making it compatible with Android and Windows phones, for example - as well as improving the user experience. In January 2011, it added hashtags, offering users the ability to find posts and people related to common interests. As Instagram grew into one of the most popular apps in the world, tech titans took notice. In 2012, Facebook purchased Instagram for one billion dollars.

In November 2012, Instagram launched web versions of user profiles, giving desktop users the ability to access Instagram profiles. However, the website profile launch retained limited functionality and lacked a search bar; the feature was redesigned in 2015. Instagram also began allowing the upload of non-square photos to the app in August 2015, a notable shift from the look and feel of the app since its inception. Rather than cropping down larger photos to a neat square, users could upload any photo of any dimension to share with friends and followers.

In March 2016, Instagram changed the nature of its news feed, the place where users scroll through newly-posted photos from those they follow, from chronological to algorithmic. “Algorithmic” means that Instagram uses computer algorithms and artificial intelligence to make “decisions” on what its data predicts you’ll like best. While this decision was met with backlash at first, it was made in order to prevent users from missing important posts from friends and family that might have gone unnoticed with a standard chronological timeline approach. Later in 2016, the app underwent major aesthetic changes; the app itself revamped to a black-and-white theme, while the app icon changed to a whimsical rainbow-colored design.

Today, Instagram boasts 800 million users. Every day, 55 million photos are uploaded and 1.2 billion likes are recorded.

In the last paragraph, why is “decisions” in quotation marks?

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:
According to sociologists, there are several different ways in which a person may become recognized as the leader of a social group in the United States. In the tamily, traditional cultural patterns confer leadership on one or both of the parents. In other cases, such as friendship groups, one or more persons may gradually emerge as leaders, although there is no formal process of selection. In larger groups, leaders are usually chosen formally through election or recruitment.
Although leaders are often thought to be people with unusual personal ubility, decades ot research have failed to produce consistent evidence that there is any category ot “natural leaders”. It seems that there is no set of personal qualities that all leaders have in common; rather, virtually any person may be recognized as a leader if the person has qualities that meet the needs ot that particular group.
Furthermore, although it is commonly supposed that social groups have a single leader, research suggests that there are typically two different leadership roles that are held by different individuals. Instrumental leadership is leadership that emphasizes the completion of tasks by a social group.
Group members look to instrumental leaders to “get things” done.” Expressive leadership, on the other hand, is leadership that emphasizes the collective well-being of a social group’s member. Expressive leaders are less concerned with the overall goals of the group than with providing emotional support to group members and attempting to minimize tension and conflict among them. Group members expect expressive leaders to maintain stable relationships within the group and provide support to individual members.
Instrumental leaders are likely to have a rather secondary relationship to other group members. They give orders and may discipline group members who inhibit attainment of the group’s goals. Expressive leaders cultivate a more personal or primary relationship to others in the group. They offer sympathy when someone experiences difficulties or is subjected to discipline, are quick to lighten a serious moment with humor, and try to resolve issues that threaten to divide the group. As the differences in these two roles suggest, expressive leaders generally receive more personal affection from group members; instrumental leaders, if they are successful in promoting group goals, may enjoy a more distant respect.

The word “them” in the third paragraph refers 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:
Around 365 B.C. in ancient Greece, the great teacher Plato told a story about a place called Atlantis. Plato described Atlantis as a continent in the Atlantic Ocean. He said it had been the home of a powerful people who were destroyed when the continent was swallowed by the sea.
Ever since Plato’s time, people have wondered if the story about Atlantis was really true. Was there ever such a place as Atlantis? During the Middle Ages, many people believed in the legend of Atlantis. Some men even made voyages to find the “lost continent”. Later, most people believed Atlantis to be just a myth. Scientists could find no evidence to show that such a place had ever existed.
Ideas change in time, however, for now some scientists think that Atlantis might have been a real place. A Greek professor has offered a new theory. He says that Atlantis was not a continent in the Atlantic Ocean but an island called Thera in the Aegean Sea. The professor says that 3,500 years ago much of Thera collapsed into the sea when a volcano erupted. He thinks that before the explosion Thera had been the home of a people called Minoans. The Minoans were sea traders who ruled the Aegean Sea from 2,000
B.C. to 1,250 B.C.
Scientist who have come to investigate Thera have found an ancient city buried beneath volcanic ash and stone. It appears that the people who lived in the city had an advanced civilization. They were probably Minoans.
Is Thera the “lost continent” of Atlantis? No one may ever know for certain. Atlantis may remain a riddle without an answer.

Which statement seems true for the passage?
