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:
We first learn about loving and caring relationships from our families. Family is  defined as   a domestic group of people with some degree of kinship - whether through blood, marriage, or adoption. Ideally, each child is nurtured, respected, and grows up to care for others and develop strong and healthy relationships. This does not mean that it is always easy to make and keep friends; it just means that we share the goal of having strong relationships.
"Family" includes your siblings and parents, as well as relatives who you may not interact with every day, such as your cousins, aunts, uncles, grandparents, and stepparents.
These are probably the people you are closest to and with whom you spend the most time.  Having healthy relationships with your family members is both important and difficult.
Families in the 21st century come in all shapes and sizes: traditional, single parent, blended  (more than one family together in the same house], and gay and lesbian parents -just to name a few. No matter the "type" of family you have, there are going to be highs and lows - good times and bad. Many times, however, families become blocked in  their relationships by  hurt, anger, mistrust, and confusion. These are natural and normal, and few families do not have at  least  a  few experiences with them. The worst time for most families, is during a divorce. By making a few  simple changes in the way we look at the world and deal with other people, it is possible to create happier, more stable relationships. Families need to be units of mutual caring and support; they can   be sources of lifelong strength for all individuals.

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

The world needs to do more to prepare for the impact of a rapidly ageing population, the UN has warned - particularly in developing countries. Within 10 years the number of people aged over 60 will pass one billion, a report by the UN Population Fund said. The demographic shift will present huge challenges to countries’ welfare, pension and healthcare systems. The UN agency also said more had to be done to tackle "abuse, neglect and violence against older persons".
The number of older people worldwide is growing faster than any other age group. The report, Ageing in the let Century: A Celebration and a Challenge, estimates that one in nine people around the world are older than 60. The elderly population is expected to swell by 200 million in the next decade to surpass one billion, and reach two billion by 2050. This rising proportion of older people is a consequence of success - improved nutrition, sanitation, healthcare, education and economic well-being are contributing factors, the report says.
But the UN and a charity that also contributed to the report, Help Age International, say the ageing population is being widely mismanaged. "In many developing countries with large populations of young people, the challenge is that governments have not put policies and practices in place to support their current older populations or made enough preparations for 2050," the agencies said in a joint statement.

Which of the following is TRUE about the older people?

The ocean bottom - a region nearly 2.5 times greater than the total land area of Earth - is a vast frontier that even today is largely unexplored and uncharted. Until about a century ago, the deep-ocean floor was completely inaccessible, hidden beneath waters averaging over 3,600 meters deep. Totally without light and subjected to intense pressures hundreds of times greater than at the Earth’s surface, the deep-ocean bottom is a hostile environment to humans, in some ways as forbidding and remote as the void of outer space.
Although researchers have taken samples of deep-ocean rocks and sediments for over a century, the first detailed global investigation of the ocean bottom did not actually start until 1968, with the beginning of the National Science Foundation’s Deep Sea Drilling Project (DSDP). Using techniques first developed for the offshore oil and gas industry, the DSDP’s drill ship, the Glomar Challenger, was able to maintain a steady position on the ocean’s surface and drill in very deep waters, extracting samples of sediments and rock from the ocean floor.
The Glomar Challenger completed 96 voyages in a 15-year research program that ended in November 1983. During this time, the vessel logged 600,000 kilometers and took almost 20,000 core samples of seabed sediments and rocks at 624 drilling sites around the world.. The Glomar Challenger’s core samples have allowed geologists to reconstruct what the planet looked like hundreds of millions of years ago and to calculate what it will probably look like millions of years in the future. Today, largely on the strength of evidence gathered during the Glomar Challenger’s voyages, nearly all earth scientists agree on the theories of plate tectonics and continental drift that explain many of the geological processes that shape the Earth.
The cores of sediment drilled by the Glomar Challenger have also yielded information critical to understanding the world’s past climates. Deep-ocean sediments provide a climatic record stretching back hundreds of millions of years, because they are largely isolated from the mechanical erosion and the intense chemical and biological activity that rapidly destroy much land-based evidence of past climates. This record has already provided insights into the patterns and causes of past climatic change - information that may be used to predict future climates.

The Deep Sea Drilling Project was significant because it was .............

In today’s fast-paced industry, learning will most likely involve seeking new skills in ways that challenge the norm. But thankfully, there is a promise for such lifelong learning online - the promise that will save your time and money while helping you earn more of both.
Provided you have access to a decent computer and the Internet, the barrier to getting started is probably lower than it ever has been. And with those things in place, it is a matter of finding the content you wish to learn. So, to help others who may be looking to maximize their own learning efforts, I have listed some quick tips below.
First, set achievable goals. When you start learning, it is a good idea to set goals about what you want to learn or what you might do with your newly acquired knowledge. It might be landing that new job, building a tangible product, or impressing your current management. The goals may vary in size and complexity, but do revisit these goals throughout your learning process. Within a couple weeks, ask yourself: “Am I getting closer to my goal?” or “Am I learning the skills necessary to reach my goals?”. If you are not, then you may need to look elsewhere.
Second, learn with others. By yourself, learning anything has a high propensity to become frustrating. Try teaming up with friends or colleagues. They can often be your best resource for maintaining motivation while you learn.
Third, make it a habit. Online habits often include scrolling through social media or watching videos on YouTube. If you have the downtime for such activities, then you could spend that downtime learning something. And why not learn something? If you do, then you will have plenty more to talk about on social media anyways. So, make learning your new online habit by making a commitment to learn something new each day.

According to the passage, what are the basic conditions for learning online?

The first Industrial Revolution was about harnessing steam power so that muscle could be replaced by machines. The second was driven by electricity and a cluster of  inventions from the late 19th century onwards - including the internal combustion engine, the aeroplane and moving pictures. A third revolution began in the 1960s and was based on digital technology, personal computing and the development of the internet. Industrial Revolution 4.0 will be shaped by  a  fresh wave of innovation in areas such as driverless cars, smart robotics, materials that are lighter and tougher, and a manufacturing process built around 3D printing.
There are some myths about Industrial Revolution 4.0. The first is that it won't really have as big an impact as the previous periods of change, most especially the breakthroughs associated with the second industrial revolution. In the past, it has always taken time to feel the full effects of technological change and many of today's advances are in their infancy. It is far too early to  say  that the car or air travel will prove to be less important than the sequencing of the human genome or synthetic biology. The second myth is that the process will be trouble free  provided  everything  is  left to the market. It is a fantasy to believe that the wealth created by the fourth  Industrial  Revolution will cascade down from rich to poor, and that those displaced will just walk into another job that pays just as well.
Indeed, all the evidence so far is that the benefits of the coming change will be concentrated among a relatively small elite, thus exacerbating the current trend towards greater levels of inequality. This was a point stressed by the Swiss bank UBS in a report launched in Davos. It notes that there will be a "polarisation of the labour force as low-skill jobs continue to  be automated and this trend increasingly spreads to middle class jobs,"

Read the passage then choose the best answer:
Music influences people in different ways or the same person differently at different times.
Music may seem to influence people differently. That is because people can react differently to the
music. We are able to apply a choosing process to the music we hear. If someone hates jazz, then a
jazz piece with a positive effect will probably not make him feel good. A happy song might appear
to make an angry person angrier, yet it is not the music itself that is creating the anger; rather it is the
positive effect of the music. The angry person does not want to accept the song's happy feeling: it
points out his already existing anger, and makes that anger come to the surface. When a piece of
music is played and we are listening to it, our body, mind, and feelings are being affected. The
musicians of ancient cultures such as China, India, Turkey and Greece understood the effects of
music. In fact, Pathagoras, in ancient Greece, introduced a whole science that concerned them.
Because the musicians of these ancient cultures understood these effects, they created music that was
positive, uplifting, and beneficial. Once the effects of music are better understood, the next step is to
gain a better understanding of the music around us, and what effect it is actually having.

Paul Watson is an environmental activist. He is a man who believes that he must do something, not just talk about doing something. Paul believes in protecting endangered animals, and he protects them in controversial ways. Some people think that Watson is a hero and admire him very much. Other people think that he is a criminal.
On July 16th, 1979, Paul Watson and his crew were on his ship, which is called the Sea Shepherd. Watson and the people who work on the Sea Shepherd were hunting on the Atlantic Ocean near Portugal. However, they had a strange prey; instead of hunting for animals, their prey was a ship, the Sierra. The Sea Shepherd found the Sierra, ran into it and sank it. As a result, the Sierra never returned to the sea. The Sea Shepherd, on the other hand, returned to its home in Canada. Paul Watson and his workers thought that they had been successful.
The Sierra had been a whaling ship, which had operated illegally. The captain and crew of the Sierra did not obey any of the international laws that restrict whaling. Instead, they killed as many whales as they could, quickly cut off the meat, and froze it. Later, they sold the whale meat in countries where it is eaten.
Paul Watson tried to persuade the international whaling commission to stop the Sierra. However, the commission did very little, and Paul became impatient. He decided to stop the Sierra and other whaling ships in any way that he could. He offered to pay $25,000 to anyone who sank any illegal whaling ship, and he sank the Sierra. He acted because he believes that the whales must be protected. Still, he acted without the approval of the government; therefore, his actions were controversial.
Paul Watson is not the only environmental activist. Other men and women are also fighting to protect the Earth. Like Watson, they do not always have the approval of their governments, and like Watson, they have become impatient. Yet, because of their concern for the environment, they will act to protect it.

When another old cave is discovered in the south of France, it is not usually news. Rather, it is an ordinary event. Such discoveries are so frequent these days that hardly anybody pays heed to them. However, when the Lascaux cave complex was discovered in 1940, the world was amazed. Painted directly on its walls were hundreds of scenes showing how people lived thousands of years ago. The scenes show people hunting animals, such as bison or wild cats. Other images depict birds and, most noticeably, horses, which appear in more than 300 wall images, by far outnumbering all other animals.
Early artists drawing these animals accomplished a monumental and difficult task. “They” did not limit themselves to the easily accessible walls but carried their painting materials to spaces that required climbing steep walls or crawling into narrow passages in the Lascaux complex.
Unfortunately, the paintings have been exposed to the destructive action of water and temperature changes, which easily wear the images away. Because the Lascaux caves have many entrances, air movement has also damaged the images inside. Although they are not out in the open air, where natural light would have destroyed them long ago, many of the images have deteriorated and are barely recognizable. To prevent further damage, the site was closed to tourists in 1963, 23 years after it was discovered.

Tides are the periodic rise and fall of the Earth’s waters that are caused by the Moon’s and Sun’s forces of gravity acting on the Earth .It is important to distinguish natural tidal phenomena from huge tsunamis , with the latter being caused by earthquakes and undersea volcanic eruptions.
The Moon is a main factor controlling ordinary tides. At the location on the Earth closest to the Moon, it exerts a powerful gravitational pull on the water. The resulting rise in the water produces higher tides. The water on the side of the Earth farthest away from the Moon also gets pulled by this lunar gravity, but not as strongly. The Earth itself has its own gravitational force that is constantly pulling waters downward, which is why the oceans do not simply bulge out toward the Moon. Ordinary tides usually feature high and low waters alternating in relation to the Earth’s rotation. Most shores around the world have high waters and two low waters for each day, which last about 24 hours and 50 minutes. The difference in height between the high water and low water is called the range of tide, and it can be quite dramatic in narrower bays
.Canada’s bays of Fundy , for example , commonly experiences the world’s most extreme tidal ranges , with daily differences of the 16 meters.
Two other types of tides are influenced by the Sun, which is much farther away from the Earth and exerts less than half of the Moon’s gravitational force. When the Sun, the Moon and the Earth are directly in line, the solar and lunar gravitational forces add up to produce higher spring tides. The range of spring tides is intensified, with higher water marks and lower low water marks. However, when the Moon is in the first or third quarter, it is at a 90–degree angle with the Sun in relation to the Earth .The opposing solar and lunar forces partially cancel each other out, and the result is a lower tide. This is called a neap tide, which comes twice a month and has lower high water marks and higher low water marks. The range of neap tides is minimum.
Some tides do not occur over water at all. The solid body of the Earth has slight elasticity, so lunar and solar gravity cause it to stretch very subtly. These changes in the Earth’s shape, although imperceptible to humans, are known as Earth tides.
Another tidal phenomenon, atmospheric tides, is caused by the Sun’s heating of the Earth’s atmosphere. Like ordinary tides, they usually occur over 12–hour periods.

What can be inferred about Canada’s Bay of Fundy ?

There are many theories about the beginning of drama in ancient Greece. The one most widely accepted today is based on the assumption that drama evolved from ritual. The argument for this view goes as follows. In the beginning, human beings viewed the natural forces of the world, even the seasonal changes, as unpredictable, and they sought, through various means, to control these unknown and feared powers. Those measures which appeared to bring the desired results were then retained and repeated until they hardened into fixed rituals. Eventually stories arose which explained or veiled the mysteries of the rites. As time passed some rituals were abandoned, but the stories, later called myths, persisted and provided material for art and drama.
Those who believed that drama evolved out of ritual also argue that those rites contained the seed of theater because music, dance, masks, and costumes were almost always used. Furthermore, a suitable site hard to be provided for the performances, and when the entire community did not participate, a clear division was usually made between the "acting area" and the "auditorium". In addition, there were performers, and since considerable importance was attached to avoiding mistakes in the enactment of rites, religious leaders usually assumed that task. Wearing masks and costumes, they often impersonated other people, animals, or supernatural beings, and mimed the desired effect- success in hunt or battle, the coming rain, the revival of the Sun as an actor might. Eventually such dramatic representations were separated from religious activities.
Another theory traces the theater's origin from the human interest in storytelling. According to this view, tales (about the hunt, war or other feats) are gradually elaborated, at first through the use of impersonation, action, and dialogue by a narrator and then through the assumption of each of the roles by a different person. A closely related theory traces theater to those dances that are primarily rhythmical  and gymnastic or that are imitation of animal movements and sounds.

"Computer programmer David Jones earns £35,000 a year designing new Computer games, yet he cannot find a bank prepared to let him have a cheque car. Instead he has been told to wait another two years, until he is 18.
 The 16-year-old boy works for a small firm in Liverpool, where the problem of most young people of age is finding a job. David’s firm releases two new games for the expanding home Computer market each month.
 But David’s biggest headache is what to do with his money. Despite his salary, earned by inventing new programmes within tight schedules with bonus payment and profit-sharing, he cannot drive a car, take out a mortgage, or obtain credit cards.
 David got his job with the Liverpool-based company four months ago, a year after leaving school with six O-levels and working for a time in a Computer shop. “I got the job because the people who run the firm knew I had already written some programmes,” he said.
 I suppose £35,000 sounds a lot but actually that’s being pessimistic. I hope it will come to records and clothes and he gives his mother £20 a week. But most of his spare time is spent working. “Unfortunately, computing was not part of our studies at school,” he said. “But I had been studying it in books and magazines for four years in my spare time. I knew what I wanted to do and never considered staying on at school. Most people in this business are fairly young anyway.”

Most of the fastening devices used in clothing today, like the shoelace, the button, and the safely pin. have existed in some form in various cultures for thousands of years. But the zipper was the brainchild of one American inventor, namely Whitcomb Judson of Chicago. At the end of the 19th century. Judson was already a successful inventor, with a dozen patents to his credit for mechanical items such as improvements to motors and railroad braking system.
He then turned his mind to create a replacement for the lengthy shoelaces which were then used in both men’s and women's boots. On August 29th 1893, he won another patent, for what he called the case “locker”. Though the model was somewhat clumsy, and frequently jammed, it did work: in fact, Judson and his business associate Lewis Walker had sewn the device into their own boots. Although Judson displayed his clasp–locker at the World's Fair held in Chicago in 1893, the public largely ignored it. The company founded by Judson and Walker, Universal Fastener, despite further refinements, never really succeeded in marketing the device.
The earliest zip fasteners were being used in the clothing industry by 1905, but it was only in 1913, after a Swedish–American engineer, Gideon Sundbach, had remodeled Judson's fastener into a more streamlined and reliable form, that the zipper was a success. The US Army applied zippers to the clothing and equipment of the troops of World War I. By the late 1920s, zippers could be found in all kinds of clothing, footwear, and carrying cases; by the mid–1930s, zippers had even been embraced by the fashion industry.
The term “zipper" was coined as onomatopoeia (resembling the sound it makes) by B.F. Goodrich whose company started marketing rubber shoes featuring the fastener in 1923. Regrettably. Whitcomb Judson died in 1909, and never heard the term, or saw the success by which his invention would become popular.

According to the passage, zippers did not really become a success until     .

By mid-century, there will likely be 9 billion people on the planet, consuming ever more resources and leading ever more technologically complex lives. What will our cities be like? How much will artificial intelligence advance? Will global warming trigger catastrophic changes, or will we be able to engineer our way out of the climate change crisis?
Making predictions is, by nature, a dicey business, but to celebrate the 40th anniversary of Smithsonian magazine Big Think asked top minds from a variety of fields to weigh in on what the future holds 40 years from now. The result is our latest special series, Life in 20 50. Demographic changes in world population and population growth will certainly be dramatic. Rockefeller University mathematical biologist Joel Cohen says it's likely that by 2050 the majority of the people in the world will live in urban areas, and will have a significantly higher average age than people today. Cities theorist Richard Florida thinks urbanization trends will reinvent the education system of the United States, making our economy less real estate driven and erasing the divisions between home and work.
Large migrations from developing countries like Indonesia, Malaysia, Bangladesh, Mexico, and countries in the Middle East could disrupt western governments and harm the unity of France, Germany, Spain, the Netherlands, Poland, and the United Kingdom under the umbrella of the European Union.
And rapidly advancing technology will continue ever more rapidly.
