While fats have lately acquired a bad image, one should not forget how essential they are. Fats provide the body's best means of storing energy, far more effiient energy sources than either carbohydrates or protein. They act as insulation against cold as cushioning for the internal organs, and as lubricants. Without fats, energy would be no way to utilize fat soluble vitamins. Furthermore, some fats contain fatty acids that contain necessary growth factors and help with the digestion of other foods. An important consideration of fat intake is the ratio of saturated fats to unsaturated fats. Saturated fats, which are derived from dairy products, animal fats, and tropical oils, increase the amount of cholesterol in the blood. Cholesterol may lead to coronary heart disease by building up in the arteries of the heart. However, unsaturated fats, derived from vegetable oils, tend to lower serum cholesterol if taken in proportion twice that of saturated fats. The consumption of a variety of fats is necessary, but the intake of too much fat may lead to a variety of health problems. Excessive intake of fats, like all nutritional excesses, is to be avoided.

The International Ecotourism Society (TIES), a non-profit organization committed to promoting sustainable tourism, states that ecotourism unites conservation and communities with sustainable travel. With that being said, they offer six core principles of ecotourism that vacationers should follow: minimize impact, build environmental and cultural awareness and respect, provide positive experiences for both visitors and hosts, provide direct financial benefits for conservation, provide financial benefits and empowerment for local people, and raise sensitivity to host countries’ political, environmental, and social climate. Ecotourism offers the opportunity to help protect and maintain our planet. Beginning with responsible travel, sustainable tourism promotes green practices such as recycling and using organic products. There are also many environmental programs and initiatives made available so that people can get involved with sustainability. For example, in Kenya, tourists can get involved with the Basecamp Foundation, which has a monitoring program for big cats and elephants. These kinds of experiences try to demonstrate the positive impact of tourism and teach tourists about the significance of maintaining the environment. However, the simple act of being a tourist in a fragile, natural area helps a great deal, as the money spent there assists in raising funds to protect those areas for generations. Sustainable tourism supports local communities by allowing their economy to grow. Tourism alone employs a large number of local staff. This in turn empowers communities to fight against poverty and encourages the support of local events, festivals, and organizations. As a result the community and its local businesses thrive.  Not only is ecotourism an environmentally fun experience, but it’s also educational. By embarking on an ecotourism vacation, people gain an awareness and understanding of the social and economic conditions of the place they visit. In addition, vacationers learn to appreciate the area’s environment through conservation and also to respect the culture of the local people. While tourists are normally unaware of a country’s poverty or ill conditions, ecotourism strives to expose tourists to the realities of these areas. Ecotourism is a new holiday experience that mixes together vacation fun with conservation and education. Sustainable tourism creates environmentally aware individuals and helps develop their appreciation of nature and local culture. Not only do vacationers go home with new knowledge, but also a worthwhile experience.  
4. The word “empowers” in paragraph 3 is closest in meaning to _______

Read the following passage and choose the best answer (A, B, C, D):
Political and economic reforms launched in 1986 have transformed the country from  one of the poorest in the world, with per capita income around US $100, to lower middle income status within a quarter of a century with per capita income of around US$ 2,100 by the end of 2015.  Vietnam’s per capita GDP growth since 1990 has been among the fastest in the world, averaging 5.5 percent a year since 1990, and 6.4 percent per year in the 2000s. Vietnam’s economy continued to strengthen in 2015, with estimated GDP growth rate of 6.7 percent for the whole year.  The Vietnamese population is also better educated and has a higher life expectancy than most countries with a similar per capita income. The maternal mortality ratio has dropped below the upper-middle-income country average, while under-five mortality rate has fallen by half, to a rate slightly above that average. Access to basic infrastructure has also  improved substantially. Electricity is now available to almost all households, up from less than half in 1993. Access to clean water and modern sanitation has risen from less than 50 percent of all households to more than 75 percent.  Vietnam’s Socio-Economic Development Strategy (SEDS) 2011-2020 gives attention to structural reforms, environmental sustainability, social equity, and emerging issues of macroeconomic stability. It defines three “breakthrough areas”: promoting human resources/skills development (particularly skills for modern industry and innovation), improving market institutions, and infrastructure development. In addition, the five-year Socio-Economic Development Plan 2011-2015 focused on three critical restructuring areas - the, banking sector, state-owned enterprises and public investment that are needed to achieve these objectives. The recent draft of the SEDP 20162020 acknowledges the slow progress of the reform priorities of the SEDP 2011-2015. With agriculture still accounting for almost half the labor force, and with significantly lower labor productivity than in the industry and services sectors, future gains from structural transformation could be substantial. The transformation from state to private ownership of the economy is even less advanced. The state also wields too much influence in allocating land and capital, giving rise to heavy economy wide inefficiencies. So, adjusting the role of the state to support a competitive private sector-led market economy remains a major opportunity. This will be important for enhancing productivity growth which has been stagnating for a long time.

Andrew Jackson Beard lived an extraordinary life for a black American inventor. Unlike the vast majority of inventors who never profit from their patents, he profited from his inventions. Andrew Beard was born a slave on a plantation in Woodland, Alabama, in 1849, shortly before slavery ended. He received emancipation at age 15 and he married at age 16. Andrew Beard was a farmer, carpenter, blacksmith, a railroad worker, a businessman and finally an inventor. He grew apples as a farmer near Birmingham, Alabama for five years before he built and operated a flour mill in Hardwicks, Alabama. His work in agriculture led to tinkering with improvement for plows. In 1881, he patented his first invention, an improvement to the double plow, and sold the patent rights for $4,000 in 1884. His design allowed for the distance between the plow plates to be adjusted. That amount of money would be the equivalent of almost $100,000 today. In 1887, Andrew Beard patented a second plow and sold it for $5,200. This patent was for a design that allowed the pitch of the blades of plows or cultivators to be adjusted. The amount he received would be the equivalent of about $130,000 today. In 1897, Andrew Beard patented an improvement to railroad car couplers. His improvement came to be called the Jenny Coupler. It was one of many that aimed to improve the knuckle coupler patented by Eli Janney in 1873 (patent US138405). The knuckle coupler did the dangerous job of hooking railroad cars together, which formerly was done by manually placing a pin in a link between the two cars. Beard, himself had lost a leg in a car coupling accident. As an ex-railroad worker, Andrew Beard had the right idea that probably saved countless lives and limbs. Beard received three patents for automatic car couplers. These are US594059 granted November 23, 1897, US624901 granted May 16, 1899, and US807430 granted on May 16, 1904. While there were thousands of patents filed at the time for car couplers, Andrew Beard received $50,000 for the patent rights to his Jenny coupler. This would be just shy of 1.5 million dollars today. Congress enacted the Federal Safety Appliance Act at that time to enforce using automatic couplers. Andrew Jackson Beard was inducted into the National
Inventors Hall of Fame in 2006 in recognition of his revolutionary Jenny coupler

There has been much debate over the past few decades concerning fears that automation will lead to robots replacing human workers on a massive scale.
The increasing use of robotics, computers and artificial intelligence is a reality, but its full implications are far from cut and dried. Some forecasts present the future in a utopian way, claiming that robots will take over the tedious heavy work thus freeing up human time and potential, allowing for more creativity and innovation. At the other end of spectrum are those who foresee an employment apocalypse, predicting that almost fifty percent of all American jobs could vanish within the next few decades. Former Microsoft chairman Bill Gates states that in 20 years robots could be in place in a number of job categories, particularly those at lower end of the scale in terms of skills.
The bottom line is that while the future is always uncertain, robots are a fixture of our society, which is not going to disappear. As with the Industrial Revolution, where machines were utilized in many tasks in place of manual laborers and social upheaval followed, the Digital Revolution is likely to place robots in various jobs. In spite of that, many of today’s jobs were not in existence before the Industrial Revolution, such as those of programmers, engineers and data scientists. This leads other experts to criticize this alarmist approach of robot scare-mongering, which is invariably compared to the 19th-century “Luddites”. This group was textile workers who feared being displaced by machines and resorted to violence, burning down factories and destroying industrial equipment – their rejection of inevitable progress has come to symbolize mindless ignorance.
Needless to say, exactly what new kinds of jobs might exist in the future is difficult to envision at present. Therefore, the crux of the issue is not whether jobs will be lost, but whether the creation of new vacancies will outpace the ever-increasing number of losses and what skills will be required in the future.
It is clearly not all doom and gloom, as demand for employees with skills in data analysis, coding, computer science, artificial intelligence and human-machine interface is rising and will continue to do so. Furthermore, the demand for skills in jobs where humans surpass computers, such as those involving  care, creativity and innovative craftmanship, are likely to increase considerably. Ultimately, the key lies in the adaptation of the workforces, through appropriate education and training, to keep pace with our world’s technological progress.

Why is the example of the Industrial Revolution given?

Read the following passage and choose the best answer (A, B, C, D):
Although experts agree that traditional meetings are essential for making certain decisions and developing strategy, many employees view them as one of the most unnecessary parts of the workday. The result is not only hundreds of billions of wasted dollars, but the worsening of what psychologists call “meeting recovery syndrome”: time spent cooling off and regaining focus after a useless meeting.  It’s isn’t anything novel that workers feel fatigued after a meeting, but only in recent decades have scientists deemed the condition worthy of further investigation. Meeting recovery syndrome (MRS) is most easily understood as a slow replenishment of our limited mental resources. When an employee sits through an ineffective meeting their brain power is essentially being drained away, says Joseph A. Allen, a professor at the University of Utah. If they last too long, fail to engage employees or turn into lectures with little to no personal interactions, meetings will significantly diminish employees’ psychological stamina. Taking time to recover a must, but doing so comes at the expense of productivity.  As humans, when we transition from one task to another – such as from sitting in a meeting to doing normal work – it takes an effortful cognitive switch. We must make a big mental effort to stop the previous task and then expend significant mental energy to move on to the other. Some can bounce back from horrible meetings rather quickly, while others carry their fatigue until the end of the workday. It’s even worse when a worker has several meetings that are separated by only 30 minutes.  While no counter-MRS measures have been tested, Allen says one trick that might work is for employees to identify things or locations that quickly change their mood from negative to positive. As simple as it sounds, finding a personal happy place, going there and then coming straight back to work might be the key to reducing recovery time. Another solution is to ask ourselves if our meetings are even necessary in the first place. If all that’s on the agenda is a quickly catch-up, or some non-urgent information sharing, it may better for managers to send an e-mail to his or her subordinates instead. Most important, however, if for organizations to awaken to the concept of meetings being flexible, says Allen. We have to get rid of the acceptance of meetings as sites of pain, when they should be places of gain.” Allen says.

Music can bring us to tears or to our feet, drive us into battle or lull us to sleep. Music is indeed remarkable in its power over all humankind, and perhaps for that very reason, no human culture on earth has ever lived without it. From discoveries made in France and Slovenia, even Neanderthal man, as long as 53,000 years ago, had developed surprisingly sophisticated, sweet- sounding flutes carved from animal bones. It is perhaps then, no accident that music should strike such a chord with the limbic system – an ancient part of our brain, evolutionarily speaking, and one that we share with much of the animal kingdom. Some researchers even propose that music came into this world long before the human race ever did. For example, the fact that whale and human music have so much in common even though our evolutionary paths have not intersected for nearly 60 million years suggests that music may predate humans. They assert that rather than being the inventors of music, we are latecomers to the musical scene.
Humpback whale composers employ many of the same tricks that human songwriters do. In addition to using similar rhythms, humpbacks keep musical phrases to a few seconds, creating themes out of several phrases before singing the next one. Whale songs in general are no longer than symphony movements, perhaps because they have a similar attention span. Even though they can sing over a range of seven octaves, the whales typically sing in key, spreading adjacent notes no farther apart than a scale. They mix percussive and pure tones in pretty much the same ratios as human composers – and follow their ABA form, in which a theme is presented, elaborated on and then revisited in a slightly modified form. Perhaps most amazing, humpback whale songs include repeating refrains that rhyme. It has been suggested that whales might use rhymes for exactly the same reasons that we do: as devices to help them remember. Whale songs can also be

rather catchy. When a few humpbacks from the Indian Ocean strayed into the Pacific, some of the whales they met there quickly changed their tunes – singing the new whales’ songs within three short years. Some scientists are even tempted to speculate that a universal music awaits discovery.

Business dealings are becoming more and more commonplace in Vietnam, as the  country’s economy is expanding at an unprecedented rate. In order to gain the respect and favour of any prospective business partners in the country, it is important to familiarise yourself with practices and etiquette that are integral to successful commerce. Doing so will communicate not only your familiarity with their way of life, but also your suitability as a partner and will underline your business acumen.  Regarding business meeting, the first meeting should not discuss business and should be seen only as an opportunity to get to know your counterpart and cultivate a good working relationship with them. While placing hands together and bowing your head is the traditional form of greeting in Vietnam, it has been all but eradicated by the westernisation of society. As a result, you should always shake the hand of a person you are meeting for the first time - especially if they are of the same sex. When meeting a female, you should wait for her to extend her hand first; if she does not, simply nod your head. Follow your new colleague’s lead in all matters. If they shake with both hands (left hand placed upon top of right), do the same.  The next important point is that the exchange of business cards is an important ritual in Vietnamese culture. Because of this, always make sure you bring a business card to exchange at any meeting, no matter how small or trivial it may seem. Ideally, this will be printed in both English and Vietnamese and you should always offer it using both hands. When receiving a card from someone else, accept it with both hands and study it thoroughly before putting it away to show respect. The translation of all documents into Vietnamese will demonstrate your regard for your prospective partners and your preparation in the business world.  
2. How did Vietnamese business people use to greet each other formally?

Read the following passage and choose the best answer (A, B, C, D):
There are many thoughts on the origins of civilization. One of the major factors  involved was the increase in population. The development of techniques, primarily irrigation and food control, which permitted agriculture in special areas such as the flood plain of the Tigris and Euphrates rivers, made possible the support of large population. Once populations reach a certain number, the older pattern of social organization breaks down and new ones develop. Specifically the older system whereby each individual participated in food production and maintained a similar standard of living, and whereby kinship served as the basic method of social organization, was replaced by the occupational division of labor, political and religious hierarchies, public works such as road and public building construction, class systems, codes of law, markets, new forms of warfare, and urban centres. Allied with these important sociological traits are material traits, such as monumental architecture and development of science and, in many cases, metallurgy and writing systems.  The earliest civilization, Sumer, developed in the Middle East. This was the Bronze Age of the Old World, during which people first developed the art of metallurgy, civilization also arose in other parts of the Old World first in Egypt, China and India, and later in Europe and Africa. At this time, civilization also developed independently in the New World, in the Mexican area and in Peru and its neighboring areas.  In the Old World the Bronze Age was followed by the Iron Age, which saw the rise and fall of great empires and the shift of power from the Middle East to Greece and Rome and then to Western Europe. In the 1700s the Industrial Age began, leading directly to the modern civilization of today. 
3. Which of the following is NOT true according to the passage?

Read the following passage and choose the best answer (A, B, C, D):
The cities in the United States have been the most visible sponsors and beneficiaries  of projects that place art in public places. They have shown exceptional imagination in applying the diverse forms of contemporary art to a wide variety of purposes. The activities observed in a number of “pioneer” cities sponsoring art in public places - a broadening exploration of public sites, an increasing awareness among both sponsors and the public of the varieties of contemporary artistic practice, and a growing public enthusiasm - are increasingly characteristic of cities across the country. With many cities now undergoing renewed development, opportunities are continuously emerging for the inclusion or art in new or renewed public environments, including buildings, plazas, parks, and transportation facilities. The result of these activities is a group of artworks that reflect the diversity of contemporary art and the varying character and goals of the sponsoring communities.  In sculpture, the projects range from a cartoonlike Mermaid in Miami Beach by Roy Lichtenstein to a small forest planted in New York City by Alan Sonfist. The use of murals followed quickly upon the use of sculpture and has brought to public sites the work of artists as different as the realist Thomas Hart Benton and the Pop artist Robert Rauschenberg. The specialized requirements of particular urban situations have further expanded the use of art in public places: in Memphis, sculptor Richard Hunt has created a monument to Martin Luther King, Jr., who was slain there; in New York, Dan Flavin and Bill Brand have contributed neon and animation works to the enhancement of mass transit facilities. And in numerous cities, art is being raised as a symbol of the commitment to revitalize urban areas.  By continuing to sponsor projects involving a growing body of art in public places, cities will certainly enlarge the situations in which the public encounters and grows familiar with the various forms of contemporary art. Indeed, cities are providing artists with an opportunity to communicate with a new and broader audience. Artists are recognizing the distinction between public and private spaces, and taking that into account when executing their public commissions. They are working in new, often more durable media, and on an unaccustomed scale.
8. According to paragraph 3, artists who work on public art projects are doing all of the following EXCEPT ____.

Language preservation is the effort to prevent languages from becoming unknown. A language is at (1)______ of being lost when it no longer is taught to younger generations, while fluent speakers of the language (usually the elderly) die. Language is an important part of any society, because it enables people to communicate and express themselves. When a language dies (2)_______, future generations lose a vital part of the culture that is necessary to completely understand it. This makes language a vulnerable aspect of cultural heritage, and it becomes especially important to (3) __________ it. According to the United Nations Educational, Scientific, and Cultural Organization (UNESCO), from facts published in their “Atlas of Languages in Danger of Disappearing,” there are an estimated 6,000 languages spoken worldwide today, and half of the world’s population speaks the eight most common. More than 3,000 languages are reportedly spoken by fewer than 10,000 people each. Ethnologue, a reference work published by SIL International, has cataloged the world’s known (4)_______ languages, and it estimates that 417 languages are on the verge of extinction. There are different factors that can (5)________ a language in danger of becoming extinct. One is when a language is no longer being taught to the children of the community, or at least to a large number of the children. In these cases, the remaining fluent speakers of the language are generally the older members of the community, and when they pass away, the language dies out with them

Read the following passage and choose the best answer (A, B, C, D):
Modern society has given significant attention to the promises of the digital economy over the past decade. But it has given little attention to its negative environmental footprint. Our smartphones rely on rare earth metals, and cloud computing, data centers, artificial intelligence and cryptocurrencies consume large amounts of electricity, often sourced from coal-fired power plants. These are crucial blind spots we must address if we hope to capture the full potential of the digital economy. Without urgent system-wide actions, the digital economy and green economy will be incompatible with each other and could lead to more greenhouse gas emissions, accelerate climate change and pose great threats to humanity. The world’s data centers-the storehouses for enormous quantities of information - consume about three percent of the global electricity supply (more than the entire United Kingdom), and produce two percent of global greenhouse gas emissions-roughly the same as global air travel. A report by Greenpeace East Asia and the North China Electric Power University found that China’s data centers produced 99 million tonnes of carbon dioxide in 2018, the equivalent of about 21 million cars driven for one year. Greenhouse gases aren’t the only type of pollution to be concerned about.Electronic waste (e-waste), which is a byproduct of data center activities, accounts for two percent of solid waste and 70 percent of toxic waste in the United States. Globally, the world produces as much as 50 million tonnes of electronic e-waste a year, worth over US$62.5 billion and more than the GDP of most countries. Only 20 percent of this e-waste is recycled. The world and its intractable challenges are not linear-everything connects to everything else. We must raise awareness about these major blind spots, embrace systems leadership (leading across boundaries), boost circular economy ideas (decoupling economic activity from the consumption of finite resources), leverage an eco-economics approach (an environmentally sustainable economy) and encourage policy-makers to explore the interrelationships between government-wide, system-wide and societal results. We must also consider collective problem-solving by bringing together diverse perspectives from both the Global North and the Global South. We should take an inventory of the global and local damages caused by electronic devices, platforms and data systems, and frame issues about the digital economy and its environmental impact in broad societal terms.
8. Which of the following can be inferred from the passage?

Read the following passage and choose the best answer (A, B, C, D):
Many of us experience multiple queues on an average day. If the move quickly,  they’re soon forgotten. But a slow line can be extremely annoying. What separated a good queuing experience from a bad one, however, is not just the speed of the line. In fact, how the wait makes us feel can have a greater impact on our perception of a queues than how much time we spend in it.  To understand how, consider the story of an airport getting complaints for the long waits at the baggage carousel. After trying fruitlessly to make baggage delivery faster, the airport simple moved the arrival gates outside of the main terminal, making people walk six times longer. Time was spent walking instead of waiting around and complaints dropped to almost zero as a result. A similar example can be observed during the postwar boom in high rise buildings in many elevator halls, where mirrors are installed to give people a chance to adjust their clothes and make sure that they look great, which distracts them from the long wait for their elevator.
For many people, the golden standard of line design and management can be found in theme parks, where waiting lines are such as integral part that companies are not afraid to invest. Some of the tricks theme parks use to make waits more bearable are hiding the line behind corners or walls to make it appear shorter and inflating the waiting times announced at each attraction. If the sign says the wait is an hour, often it will actually be more like 45 minutes, which will make people feel like they’re 15 minutes ahead of schedule. At Disneyland, designers and engineers also add games and other activities in order to give guests plenty to do, which keeps them from measuring the passage of time. According to Larson, Disney lines are so entertaining that on rainy days, when attendance is low, rides in the parks may fill up too slowly because families linger in the queue for too long.  Clever line design can also be found in supermarkets. Multiple parallel lines, each in front of a checkout, can be great if you’re in a fast one, but can feel very unfair if you’re stuck in a slow one. That’s why businesses are increasingly switching to the serpentine line, in which all customers are funneled into a single queue and then sent to the first available checkout. Compared to parallel lines, the serpentine triumphs in the key department of fairness: it’s strictly first come, first served, so no one arriving after you can be served before you
6.  Based on paragraph 4, which of the following is TRUE about the serpentine line?

The field of 3-D printing comes with a new set of legal questions hospitals using the  technology will need to consider, said Bruce Kline, a technology licensing manager who oversees patents for new technology developed at Mayo Clinic. For starters, he said the STL file printers use are a lot like MP3 music files, in that they can be protected under copyright and require licensing to use. Copyright violations can occur if a purchased STL anatomical model file for rare disease is illegally shared with another institution that did not purchase the file from the vendor that created the file.  Under the law, if a device has a functional use it falls under patent law. If it is not functional, it falls under copyright law. Kline said most medical 3-D printing for educational models and complex anatomy evaluation currently falls under copyright. But, he said that will rapidly change in the coming years as customizable 3-D printable medical devices see wider use.  Additive manufacturing (AM) allows the creation of patient-specific devices at the point of care. Kline said an interesting fact is that these devices are FDA 510(k)-exempt if produced by a hospital instead of a medical device vendor. He said this blurs the lines between traditional vendor relationships, since the hospital can now become the manufacturer. However, if a hospital makes a device, it also becomes liable for it. He advised that it might be better for a commercial vendor to make the device for the hospital so the vendor assumes the liability of the device. Custom-made medical devices are also exempt under FDA regulations, Kline said. So, if a physician creates or modifies a device to meet the clinical needs of a specific patient’s anatomy, he said it is acceptable to use under current FDA rules. This may leave the door wide open for use of 3-D printed devices that are customized for each patient using their own 3-D imaging datasets.  It is possible printable device files may become available in the next few years to customize and print on demand. However, Kline said it will be much more difficult to enforce patents on these types of devices. He explained if someone makes one or two devices, there is no economical way for the creator of those device files to go after the user/maker of of unlicensed copies of the device to claim lost profits.

New data from Akamai, an internet delivery and cloud services company, has exposed that the video game industry remains a growing threat vector for security breaches. Hackers have targeted 12 billion credential stuffing attacks against game websites within a 17-month period The rise and success of credential stuffing attacks is a result of people continuing to reuse the same passwords across multiple accounts. Google identified that 59% of online users reuse passwords. When a data breach happens, user credentials are exposed and can subsequently be found on the internet and the dark web. Cybercriminals use a bot with a list of exposed credentials against a website to gain access to an account on that site. The reason that gaming is subject to so many breaches is twofold; No. 1, most video game companies use low-friction authentication measures because increasing friction drives customer attrition and results in a loss of revenue. The second issue is that from a consumer perspective, gaming is seen as having a low financial risk and, as a result, gamers tend to use less secure passwords. Adding to these challenges is the fact that game developers are pressured to deliver more products at a faster pace, meaning there are more bugs and security issues for cybercriminals to exploit. This has created a perfect storm in the video game industry upon which hackers are all too eager to capitalize.   A significant number of gamers are young — elementary, middle, and high schoolaged — who are less security-conscious and more trusting of people they meet online. To them, privacy is a learned behavior leaving them open to exploitation. They may need to be taught best practices to safeguard their accounts and understand the risks of using weak passwords linked to the games they play. Providing a seamless online experience is paramount in the digital age and, as a result, many organizations balk at implementing robust security procedures for fear of alienating customers. The challenge for the video game industry is to find a balance between increased security without frustrating its players. One notable exception is Microsoft, which has deployed vigorous security measures with Xbox in line with the rest of its business. Without a fundamental change in approach from both gamers and the industry overall, the escalation of this problem shows no signs of slowing down.  
1. Which best serves as the title for the passage?

Mark the letter A, B, C, or D on your answer sheet to indicate the undelined part that needs correction in each of the following questions:
If parents bring up a child with the sole aim of turning the child into a genius, they will cause a disaster. According to several leading educational psychologists, this is one of the biggest mistakes which ambitious parents make. Generally, the child will be only too aware of what his parents expect, and will fail. Unrealistic parental expectations can cause great damage to children.
However, if parents are not too unrealistic about what they expect their children to do, but are ambitious in a sensible way, the child may succeed in doing very well — especially if the parents are very supportive of their child. Michael Collins is very lucky. He is crazy about music, and his parents help him a lot by taking him to concerts and arranging private piano and violin lessons for him. They even drive him 50 kilometers twice a week for violin lessons. Michael's mother knows very little about music, but his father plays the trumpet in a large orchestra. However, he never makes Michael enter music competitions if he is unwilling.
Winston Smith, Michael's friend, however, is not so lucky. Both his parents are successful musicians, and they set too high a standard for Winston. They want their son to be as successful as they are and so they enter him for every piano competition held. They are very unhappy when he does not win. Winston is always afraid that he will disappoint his parents and now he always seems quiet and unhappy.

The word "They" in the passage refers to     .
