Read the following passage and choose the best answer (A, B, C, D):
The human desire for companionship may feel boundless, but research suggests that  our social capital is finite. Social scientists have used a number of ingenious approaches to gauge the size of people’s social networks; these have returned estimates ranging from about 250 to about 5,500 people. An undergraduate thesis from MIT focusing exclusively on Franklin D. Roosevelt, a friendly guy with an especially social job, suggested that he might have had as many as 22,500 acquaintances. Looking more specifically at friendship, a study using the exchange of Christmas cards as a proxy for closeness put the average person’s friend group at about 121 people.  However vast our networks may be, our inner circle tends to be much smaller. The average American trusts only 10 to 20 people. Moreover, that number may be shrinking: From 1985 to 2004, the average number of confidants that people reported having decreased from three to two. This is both sad and consequential, because whoever has strong social relationships tends to live longer than those who don’t. So what should you do if your social life is lacking? Just follow the research. To begin with, don’t dismiss the humble acquaintance. Even interacting with people with whom one has weak social ties has a meaningful influence on well-being. Beyond that, building deeper friendships may be largely a matter of putting in time. A recent study out of the University of Kansas found that it takes about 50 hours of socializing to go from acquaintance to casual friend, an additional 40 hours to become a “real” friend, and a total of 200 hours to become a close friend. If that sounds like too much effort, reviving dormant social ties can be especially rewarding. Reconnected friends can quickly recapture much of the trust they previously built, while offering each other a dash of novelty drawn from whatever they’ve been up to in the meantime. And if all else fails, you could start randomly confiding in people you don’t know that well in hopes of letting the tail wag the relational dog. The academic literature is clear: Longing for closeness and connection is pervasive. Which suggests that most of us are stumbling through the world pining for companionship that could be easily provided by the lonesome stumblers all around us.

It is many peoples dream to become a world-famous artist. Unfortunately, it can be extremely difficult to make a living solely from selling your paintings or sculptures. But don’t worry because there are other jobs in the world of art that you can pursue. One possible career option is to become an art dealer.
An art dealer works on behalf of artists to help them sell works to museums and galleries around the world. To be successful at this profession, it requires a well-rounded skill set. For starters, it helps a lot if you love art and are knowledgeable about art history. Having business skills will also be quite useful, as it will be necessary to negotiate with buyers, and help the artists you represent market their work. If becoming an art dealer sounds appealing, there are several steps which you can follow. Although you  may have a love for a wide range of styles, you should start by choosing one category to focus on. Buyers usually prefer to deal with a specialist in a particular area than someone who is a jack of all trades. When selecting your focus, choose an area that you are passionate about instead of something that seems lucrative. Art trends come and go, so there is no use trying to predict what is hot. These trends will certainly change over the course of your career.
Once you selected an area to focus on, start to contact some museums, galleries, and other companies in the art world and send them your resume. The majority of art dealers begin their careers working as interns for these kinds of companies. Although these interns may be paid little, or in some cases nothing at all, the experience of learning how art businesses work will certainly serve you down the road.
It pays to be flexible in the beginning, as the most important thing is to get your foot in the door. Museums and galleries may offer you several positions including a sales assistant or a junior art consultant. Whichever job you accept, be sure to learn it well and give it your best. In addition to your responsibilities, make sure your start to network with others in your industry. As your knowledge and contacts begin to grow, more opportunities will be open to you.

Why does the author suggest it is important to make contact at work?

It’s often said that we team things at the wrong time. University students frequently do the minimum of work because they’re crazy about a good social life instead. Children often scream before their piano practice 5 because it’s so boring. They have to be given gold stars and medals to be persuaded to swim, or have to be bribed to take exams. But the story is different when you’re older.
Over the years, I’ve done my share of adult learning. At 30, I went to a college and did courses in History and English. It was an amazing experience. For starters, I was paying, so there was no reason to be late - I was the one frowning and drumming my fingers if the tutor was late, not the other way round. Indeed, if I could persuade him to linger for an extra five minutes, it was a bonus, not a nuisance. I wasn’t frightened to ask questions, and homework was a pleasure not a pain. When I passed an exam, I had a big meal, not for my parents or my teachers. The satisfaction I got was entirely personal.
Some people fear going back to school because they worry that their brains have got rusty. But the joy is that, although some parts have rusted up, your brain has learnt all kinds of other things since you were young. It has learnt to think independently and flexibly and is much better at relating one thing to another. What you lose in the rust department, you gain in the maturity department.
In some ways, age is a positive plus. For instance, when you’re older, you get less frustrated. Experience has told you that, if you’re calm and simply do something carefully again and again, eventually you’ll get the hang of it. The confidence you have in other areas - from being able to drive a car, perhaps - means that if you can’t, say, build a chair instantly, you don’t, like a child, want to destroy your first pathetic attempts. Maturity tells you that you will, with application, eventually get there.
I hated piano lessons at school, but I was good at music. And coming back to it, with a teacher who could explain why certain exercises were useful and with musical concepts that, at the age of ten. I could never grasp, was magical. Initially, I did feel a bit strange, thumping out a piece that I’d played for my school exams, with just as little comprehension of what the composer intended as I’d had all those years before. But soon, complex emotions that I never knew poured out from my fingers, and suddenly I could understand why practice makes perfect.

Read the following passage and choose the best answer (A, B, C, D):
Children’s behaviour has worsened over the past five years, according to a survey of  teachers which found that a fifth thought girls were more likely to cause trouble than boys. The survey, published after teachers at a Lancashire school went on strike over discipline, found low-level disruption, including chatting and “horsing around”, was the biggest problem. Boys were more likely to be physically aggressive while girls tended to ostracise other pupils. The behaviour of boys was more of a challenge than that of girls but the actions of each sex had deteriorated, according to 56.5% of staff surveyed by the Association of Teachers and Lecturers (ATL).  Among male pupils the most challenging behaviour for teachers was physical aggression, such as pushing, spitting, kicking and hitting. A secondary teacher quoted in the survey said boys were usually aggressive with other pupils, while girls tended to call one another names. Teachers criticised a lack of role models in the home. A primary teacher said: “The boys are far more willing to be aggressive to adults, verbally and even physically. There don’t seem to be any parental boundaries set of what is an appropriate way to speak and deal with another adult.” Teachers at Darwen Vale high school, Lancashire, walked out over unruly pupil behaviour this month. They said children challenged them to fights and threatened to film lessons and post them online. The survey of more than 850 teachers, heads and other school staff found that more than 21% thought girls’ behaviour was more challenging than boys, compared with 68% who said male pupils caused more trouble. In schools that have excluded pupils, 57% said more boys and 5% said more girls had been excluded. A department head in a primary school told the survey, carried out in March, that “classes with a majority of boys tend to be louder, less co-operative and harder to teach”. Nearly half of the staff surveyed said boys’ bravado was behind their disruption. For girls, the most likely trigger was a break-up between friends. A primary school teacher from Bedfordshire said: "Boys are generally more physical and their behaviour is more noticeable. Girls often say nasty things, which end up disrupting the lesson just as much as the boys, as other children get upset and can’t focus on their work. They are usually the ones who refuse to comply with instructions." Some staff had noticed girls’ behaviour worsening.” A teaching assistant from Weston-super-Mare said: “Girls are definitely getting more violent, with gangs of girls in school who are getting worse than the gangs of boys.” The ATL annual conference in Liverpool on Monday is due to debate a motion expressing concern at increasing numbers of girls being excluded from secondary school.  Government figures for 2008-9 showed that boys represented 78% of the total number of permanent exclusions from schools in England. This proportion was unchanged from the year before. The ATL general secretary, Mary Bousted, said: "Staff get ground down daily by the chatting and messing around, which disrupts lessons for other pupils and takes the pleasure out of teaching. Even more worrying is the physical aggression, most often among boys but also among some girls, which puts other pupils and staff at risk. Schools need to have firm and consistent discipline policies and work with parents to keep schools and colleges safe places for pupils and staff alike." The education bill, now going through the Commons, will give teachers the right to search pupils for banned items and will remove the requirement to give parents a day’s notice of detention. The education secretary, Michael Gove, said the measures in the bill would “restore discipline” in the classroom.
5. What could the word “comply” in paragraph 3 best be replaced by?

It used to be that people would drink coffee or tea in the morning to pick them up and get them going for the day. Then cola drinks hit the market. With lots of caffeine and sugar, these beverages soon became the pick-me-up of choice for many adults and teenagers. Now drink companies are putting out so-called "energy drinks." These beverages have the specific aim of giving tired consumers more energy.

One example of a popular energy drink is Red Bull. The company that puts out this beverage has stated in interviews that Red Bull is not a thirst quencher. Nor is it meant to be a fluid replacement drink for athletes. Instead, the beverage is meant to revitalize a tired consumer's body and mind. In order to do this, the makers of Red Bull, and other energy drinks, typically add vitamins and certain chemicals to their beverages. The added chemicals are like chemicals that the body naturally produces for energy. The vitamins, chemicals, caffeine, and sugar found in these beverages all seem like a sure bet to give a person energy.

Health professionals are not so sure, though. For one thing, there is not enough evidence to show that all of the vitamins added to energy drinks actually raise a person's energy level. Another problem is that there are so many things in the beverages. Nobody knows for sure how all of the ingredients in energy drinks work together.

Dr. Brent Bauer, one of the directors at the Mayo Clinic in the US, cautions people about believing all the claims energy drinks make. He says, —It is plausible if you put all these things together, you will get a good result. || However, Dr. Bauer adds the mix of ingredients could also have a negative impact on the body. —We just don't know at this point,|| he says.

The era of “smart cities”, controlled by an ecosystem of sensors, cameras and  algorithms, is fast approaching. In China, state media claim 500 are under construction. In Canada, Alphabet has plans for turning parts of Toronto into a timber-framed tech town as a prototype. Incremental steps are also making cities smarter. Last week, Transport for London announced plans to track Tube passengers through WiFi to monitor congestion. In the US, fast-food drive-throughs will trial number plates scanners to make ordering faster. Individually these services can improve daily life. Integrating them will create something more powerful than the sum of its parts.  Though convenience and safety are the end goals, serious questions about how city authorities will both store and share vast bodies of data must be answered. The fact that surveillance is built into key transport infrastructure will also make it increasingly difficult to avoid without disrupting daily life. The smart city risks creating a panopticon in the name of an easier and better life. The risks of anonymity disappearing will be increased by the use of different data sets, making it more likely that identifiable characteristics may appear. Closely linked to this is the question of data storage and sharing. The treasure trove of personal information will be a tempting target for hackers. This information might also be used by law enforcement, feeding into the existing dangers of mass surveillance and profiling, as is already the case in China.  These concerns have long been levelled at social media and internet-enabled home appliances. Smart city surveillance can be even more insidious. Users can avoid Facebook or hardware such as Alexa. Avoiding basic infrastructure will be near impossible without seriously affecting day-to-day life. TfL has put up signs warning customers of the WiFi tracking, yet the only choice is between tracking and having no signal. Reports on the facial recognition at airports in America suggest that avoiding being automatically scanned will be tough as well. As these systems become more closely enmeshed, avoiding snooping will become increasingly tricky.  The inevitable rise of smart cities is not inherently negative. Harnessing the power of technology and data can potentially help urban environments adapt to challenges such as climate change and overcrowding. Politicians, programmers and academics must work to ensure that does not come at the cost of all-seeing, 24-hour surveillance. 
8. Which of the following can be inferred from the passage?

Read the following passage and choose the best answer (A, B, C, D):
What results in good health and longevity? It’s good genes, good lifestyle and good luck. But since we can’t choose our parents, or know what fate holds in store for us, we must treat lifestyle with tender, loving care. Now, a report “Circulation” proves that a sound lifestyle adds 12 to 14 more years to life. For instance, a woman, aged 50, who follows these lifestyle rules can expect to live to 93 years. This compares to a woman who indulges in an unhealthy lifestyle and dies at 79. In men, the increase in longevity from a healthy lifestyle is from 76 to 88 years. In the general population, the U.S. spends more money on health care than any other country. So why are so many people in North America suffering from ill health? It is quite apparent that the epidemic of obesity, type 2 diabetes and heart attack will continue to be the big killers. At the moment there is little evidence this battle is being won. But a study that followed both staff and students at the University of Liverpool shows it’s not an impossible dream. In its first experiment, female diners were randomly divided to receive either a small or large quiche for lunch. The next day, the same group were all allowed to serve themselves any portion they desired. Researchers discovered the ones who had been served the smaller portion, tended to choose the smaller portion. A second experiment tested male diners and it produced the same result. In the third experiment both sexes were included, but it was done one week later. This time diners were asked to look at various photos of portion size and asked which looked normal. Those who were previously given the smaller portions considered the smaller ones normal.  These studies showed that it is possible to shift people from what they think is a normal portion to what is actually the proper amount to eat. And that the perception of what is normal lasts at least to one week later. Remember, a voyage of a thousand miles begins with the first step. The same philosophy applies to longevity. So, gradually incorporate one thing at a time into your lifestyle. Don’t forget the importance of smaller portions, add more fruits and vegetables, buy a pedometer to check the number of steps taken each day, and to measure your progress, step on the scale every day

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.

Read the following passage and choose the best answer (A, B, C, D):
The number of people accessing the State’s and community’s priority policies and  programmes is increasing, said Minister of Labour, Invalids and Social Affairs Dao Ngoc Dung. Vietnam has around 6.2 million people over the age of two with disabilities, making up 7.06 per cent of the country’s population. Of those, 28 per cent are severely disabled, 58 per cent female, 28 per cent children and 10 per cent living in poverty. Most live in rural areas and many are victims of Agent Orange.  Minister Dung said in the past, the State, the Party and Vietnamese people had paid much care to people with disability. Vietnam ratified the United Nations’ Convention on the Rights of People with Disability in 2014. In March this year, the country ratified the International Labour Organisation’s Convention 159 about jobs for people with disability. It strongly confirmed Vietnam’s commitment ensuring the disabled would not be discriminated at work.  Last month, the Secretariat Committee issued the Instruction 39 about the Party’s leading work on affairs related to people with disability. The National Assembly later ratified the amended Law on Labour with many adjustments relating to disabled people. Dung said that every year, millions of disabled people receive an allowance from the State and all of provinces and cities had rehabilitation centres. Attending the event, Truong Thi Mai, head of the Party Central Committee’s Commission for Mass Mobilisation, said besides the achievements, Vietnam still sees many obstacles. Infrastructure is still limited demand for people with disability and many live below the poverty line depending heavily on their families.  Mai asked organisations to improve education to raise people’s awareness of the meaning of supportive work to people with disability. This year, more than VNĐ17 trillion (US$735.4 million) from the State budget was allocated to provinces and cities to implement policies for people with disability, according to the Ministry of Labour, Invalids and Social Affairs.  The Ministry of Planning and Investment on Thursday launched the programme “White stick for Vietnamese visual impaired people”. Its aim is to present one million white sticks to visually impaired people across the country. Training to use the device will also be provided. Minister of Planning and Investment Nguyen Chi Dung said the ministry will listen to disabled people’s demands and wishes and put them into its policies. Deputy chairwoman of the National Assembly Tong Thi Phong said Vietnam has committed to developing socioeconomy, taking care of social equality and improving social management ability.  
7. Which of the following statements is TRUE, according to 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:
Pollution emitted in industrial areas represents a threat to human health and the surrounding natural resources. We have a tendency to believe that the production processes are the only source of environmental damage, and often forget about the possible long-term effects of harmful production practices. We may think that the closure of these huge industrial areas would improve the quality of the environment. Unfortunately, this ignores the threat of the remaining waste, which is abandoned and poorly stored. It represents an even bigger danger because it stands neglected as it degrades and leaks into the earth without any control at all.
Changes in the water chemistry due to surface water contamination can affect all levels of an ecosystem. It can affect the health of lower food chain organisms and, consequently, the availability of food up through the food chain. It can damage the health of wetlands and damage their ability to support healthy ecosystems, control flooding, and filter pollutants from storm water runoff. The health of animals and humans are affected when they drink or bathe in contaminated water. In addition water-based organisms, like fish and shellfish, can pile up and concentrate contaminants in their bodies. When other animals or humans eat these organisms, they receive a much higher dose of contaminant than they would have if they had been directly exposed to the original contamination.
Contaminated groundwater can badly affect animals, plants and humans if it is removed from the ground by manmade or natural processes. Depending on the study of rocks of the area, groundwater may rise to the surface through springs or seeps, flow sideways into nearby rivers, streams, or ponds, or sink deeper into the earth. In many parts of fhe world, groundwater is pumped out of the ground to be used for drinking, bathing, other household uses, agriculture, and industry.
Contaminants in the soil can harm plants when they take up the contamination through their roots. Eating, breathing in, or touching contaminated soil, as well as eating plants or animals that have piled up soil contaminants can badly affect the health of humans and animals.
Air pollution can cause breathing-related  problems  and  other  bad  health  effects  as  contaminants  are absorbed from the lungs into other parts of the body. Certain air contaminants can also harm animals and humans when they contact the skin. Plants rely on breathing for their growth and can also be affected by exposure to contaminants moved in the air.

According to the passage, which of the followings supports healthy ecosystem?

Read the following passage and choose the best answer (A, B, C, D):
As places transformed, so did the people. When researchers at Yale University and the University of Westminster studied what images people associated with climate change, they found a shift this decade. When they began their study in 2003, the majority of people surveyed thought of melting polar ice. By 2016, more and more people had weather top of mind. Climate, to be clear, is not weather. It’s the difference between a trend and a one-off event. But with wetter storms and hotter summers unfolding over the course of the decade, people were making new connections between climate change and the weather. Seeing climate change through the lens of something they experience every day opens the door for people to see the weight of the issue over their own lives. “Americans are just beginning to connect the dots and to say, wait a second, what’s going on here,” says Anthony Leiserowitz, a lead author of the study and director of the Yale Program on Climate Change Communication. “There’s been this increasing dawning of awareness among many Americans that climate change is actually starting to harm people here and now.” New renewable energy projects outpaced new fossil fuel installations in worldwide growth for the first time in 2015. In a pivotal moment for the whole planet, every country on Earth agreed to take on climate change when they adopted the Paris climate accord in 2015. That committed countries to reducing their greenhouse gas emissions enough to keep the Earth from warming beyond roughly 1.5 degrees Celsius above pre-industrial levels, a threshold that could be catastrophic for people and ecosystems if it’s crossed. It was the culmination of years of political wrangling. “It is rare to have the opportunity in a lifetime to change the world,” former French president François Hollande told delegates gathered on the final day of negotiations. “Seize it so that the planet can live on, so that humanity can live on.” But cooperation, even when the health of the whole planet is on the line, can be a fragile, fleeting thing. After Donald Trump was elected president in 2016, he began the process of formally withdrawing the US from the Paris accord. One by one, Trump backtracked on existing federal efforts to cut down on pollution, too. The words “climate change” began disappearing from government websites and documents  
1. Which best serves as the title for the passage?

Read the following passage and choose the best answer (A, B, C, D):
Most households in the UK will have a broadband connection and a lot of those  houses will also have experienced connection or speed issues. But what if there was a way to connect to the internet and benefit from a direct connection with much faster speeds? Enter Li-Fi.  Li-Fi stands for Light Fidelity and is a Visible Light Communications (VLC) system which runs wireless communications that travel at very high speeds. With Li-Fi, your light blub is essentially your router. It uses common household LED light bulbs to enable data transfer, boasting speeds of up to 224 gigabits per second.  Li-Fi and Wi-Fi are quite similar as both transmit data electromagnetically. However, Wi-Fi uses radio waves, while Li-Fi runs on visible light waves. This means that it accommodates a photo-detector to receive light signals and a signal processing element to convert the data into “streamable” content. For example, data is fed into an LED light bulb, it then sends data at rapid speeds to the photo-detector. The tiny changes in the rapid dimming of LED bulbs is then converted by the “receiver” into electrical signal. The signal is then converted back into a binary data stream that we would recognise as web, video and audio applications that run on internet-enabled devices.  While some may think that Li-Fi with its 224 gigabits per second leaves Wi-Fi in the dust, Li-Fi’s exclusive use of visible light could halt a mass uptake. Li-Fi signals cannot pass through walls, so in order to enjoy full connectivity, capable LED bulbs will need to be placed throughout the home. Not to mention, Li-Fi requires the light bulb is on at all times to provide connectivity, meaning that the lights will need to be on during the day.
