Alzheimer's disease impairs a person's ability to recall memories, both distant and as a few hours before. Although there is no yet a cure for the illness, there may be hope for a cure with a protein called nerve growth factor. The protein is produced by nerve cells in the same region of the brain where Alzheimer's occurs. Based on this relationship, scientists from the University of Lund in Sweden and the University of California at San Diego designed an experiment to test whether doses of nerve growth factor could reverse the effects of memory loss caused by Alzheimer's. Using a group of rats with impaired memory, the scientists gave half of the rats doses of nerve growth factor while giving the other half a blood protein as a placebo, thus creating a control group. At the end of the four-week test, the rats given the nerve growth factor performed equally to rats with normal memory abilities. While the experiment do not show that nerve growth factor can stop the general process of deterioration caused by Alzheimer's, they do show potential as a means to slowing the process significantly.

The World Health Organization on Wednesday declared the rapidly spreading  coronavirus outbreak a pandemic. Director-General Tedros Adhanom Ghebreyesus said that “We expect to see the number of cases, the number of deaths, and the number of affected countries climb even higher.”  WHO officials had said earlier they were hesitant to call the outbreak a pandemic in case it led governments and individuals to give up the fight. On Wednesday, they stressed that fundamental public health interventions can still limit the spread of the virus and drive down cases even where it was transmitting widely, as the work of authorities and communities in China, Singapore, and South Korea has shown.  The virus, which probably originated in bats but passed to people via an as yet unrecognized intermediary animal species, is believed to have started infecting people in Wuhan, China, in late November or early December. Since then the virus has raced around the globe. South Korea, which has reported nearly 8,000 cases, also appears poised to bring its outbreak under control with aggressive measures and widespread testing. But other countries have struggled to follow the leads of China and South Korea — a reality that has frustrated WHO officials who have exhorted the world to do everything possible to end transmission of the virus. Tedros used the fact that 90% of the cumulative cases have been reported in just four countries as evidence that the rest of the world still had time to prevent an explosion of cases with action.  WHO officials also stressed that countries should be implementing a strategic combination two types of measures. One involves trying to detect and stop known chains of transmission by isolating cases and following and potentially quarantining their contacts. The other involves community-level steps like social distancing and comes into play when the virus is spreading more broadly and transmission chains can’t be tracked. Mike Ryan, the head of the WHO’s emergency program, said that the public health interventions might not have straightforward effect, but to slow the spread of the virus. People with severe cases can require long periods of critical care and strain the resources of hospitals. He said he was worried about “the case load, the demand on the health workers, the dangers that come with fatigue, and potentially shortages of personal protective equipment.”

Read the following passage and choose the best answer (A, B, C, D):
According to the report, we can expect some pretty remarkable changes to our homes  and our personal spaces, overlooked things that make up so much of our daily routine. As human populations soar, our cities and homes will have to adapt; interior living spaces will change as a cloud changes, easily reconfigured and rearranged to suit our fickle tastes, or accommodate different purposes.  Imagine walls and floors made of a malleable “skin,” and embedded with tiny sensors and actuators so that the shape and size of living spaces can quickly change, or even be divided into smaller rooms; imagine fully programmable “smart homes” that can be controlled remotely, and provide feedback to their owners - yes, there’ll even be an app for that.  Virtual decorations will alter with changing tastes, moods and whims; and the entire interior surface of the home will be implanted with LED technology - television screens and computer displays will form and unform in any room, as needed. Even our furniture will be adaptable, molding to custom fit our bodies, responding to changes in posture, or disappearing altogether when not needed.  It will be the ultimate evolution of the “Internet of Things.” Misplaced something? Can’t find your keys? No problem. Just use an online search function to find it. Hate the color of that accent wall? Delete it. Need more storage space? Watch new shelves appear, as if by magic. And the amenities are fantastic. Every home will come standard with a 3D printer; they’ll be able to churn out just about anything you could wish, using downloadable patterns, probably including even complex electronic devices. They may even print out your meals, designed and programmed by the world’s master chefs.  Walk-in “medical pods,” meanwhile, will contribute to the decentralization of healthcare - their imaging sensors will diagnose your ills and, for the more easily treatable maladies, dispense drugs, inject antibiotics, and recommend health regimens. It may even be possible to undergo remote, robot-mediated surgery, in the comfort of your own home.  This barely scratches the surface. Imagine homes whose very building material is salted with dormant limestone-producing bacteria, which awaken upon contact with moisture and repair any cracks or structural damage.  There will be “digestion tanks” full of anaerobic bacteria, to dispose of our waste; and our homes will produce, store, and reuse their own energy, using “microbial fuel cell stacks” and more efficient solar panels to generate electricity, and power-banks like the Tesla power wall to store it against future use. Personal homes will be almost fully independent of a dangerously overtaxed energy grid.  One hundred years in the future, our houses will be, in almost all respects, semiliving, artificial organisms - closed systems with a metabolism, sensory apparatus, immune response, and an approximation to a nervous system. We’ll be living in homes that are practically alive.
6. The word "They" in paragraph 5 refers to ______

Read the following passage and choose the best answer (A, B, C, D):
While light at night can be beneficial, neutral, or damaging for individual species, its presence invariably disturbs ecosystems. For example, some species of spiders avoid lit areas, while other species are happy to build their spider web directly on a lamp post. Since lamp posts attract many flying insects, the spiders that don’t mind light gain an advantage over the spiders that avoid it. Light pollution poses a serious threat in particular to nocturnal wildlife, having negative impacts on plant and animal physiology. It can confuse animal navigation, alter competitive interactions, change predator-prey relations, and cause physiological harm. The rhythm of life is orchestrated by the natural patterns of light and dark, so disruption to these patterns impacts the ecological dynamics. Studies suggest that light pollution around lakes prevents zooplankton, such as Daphnia, from eating surface algae, causing algal blooms that can kill off the lakes’ plants and lower water quality. Light pollution may also affect ecosystems in other ways. For example, scientists have documented that night time light may interfere with the ability of moths and other nocturnal insects to navigate. Night-blooming flowers that depend on moths for pollination may be affected by night lighting, as there is no replacement pollinator that would not be affected by the artificial light. This can lead to species decline of plants that are unable to reproduce, and change an area’s long term ecology. Reducing light pollution implies many things, such as reducing sky glow, reducing glare, reducing light trespass, and reducing clutter. The method for best reducing light pollution, therefore, depends on exactly what the problem is in any given instance. Adjusting the type of lights used, so that the light waves emitted are those that are likely to cause severe light pollution problems

While trust in media as a whole may be at an all-time low, a new study by the EBU has shown the public’s trust in traditional media (broadcast and the written press) is actually on the rise. However, people’s trust in new media continues to fall: 61% of European countries distrust the internet while 97% have no faith in social networks. The EBU’s new report – Trust in Media 2018 – shows the figures illustrating the differences between people’s trust in traditional and new media. Broadcast media remain the most trusted forms of media with 59% of people tending to trust radio (equivalent to 2017) and 51% trusting TV in the EU (an increase of 1 percentage point on 2017). Trust in the written press has also slowly improved over the last 5 years and it is now trusted by 47% of EU citizens. At the same time, people’s trust in the internet and social media has been eroded by fake news, misinformation and disinformation. Only 34% of EU citizens trust the internet and a mere 20% now trust social networks (down from 36% and 21% respectively in 2017). Trust in Media 2018 is based on data published in the 88th Eurobarometer survey and gives an idea of European citizens’ perception of the trustworthiness of different types of media. The survey consists of approximately 1000 face-to-face interviews in the 33 countries covered by the study. The report shows how European citizens’ trust in broadcast media is closely connected with a free and independent press. The higher the level of trust in a country’s radio and TV, the higher press freedom in that country tends to be. There are also strong regional differences with the Nordics and Albania tending to trust traditional media the most while Eastern Europeans tend to trust social networks and the internet more. The EBU’s Head of Strategy and the Media Intelligence Service Roberto Suárez Candel said: “The results of our research show that good quality, impartial media is highly valued by the public. “Public service media play an important role in that and, together, our Members make an invaluable contribution to society. The role of our public service Members in upholding democratic values and supporting media freedom is clearly demonstrated by the results of our research.”

Read the following passage and choose the best answer (A, B, C, D):
Just as optical fibers have transformed communication, they are also revolutionizing medicine. These ultra - thin, flxible fiers have opened a window into the living tissues of the body. By inserting optical fibers through natural openings or small incisions and the threading them along the body's established pathways, physicians can look into the lungs, intestines, heart and other areas that were formerly inaccessible to them. The basic fiber-optics system is called fiberscope, which consists of two bundles of fibers. One, the illuminating bundle, carries light to the tissues. It is coupled to a high-intensity light source. Light enters the cores of the high-purity silicon glass and travels along the fibers. A lens at the end of the bundle collects the light and focuses it into the other bundle, the imaging bundle. Each fibers in the bundle transmits only a tiny fraction of the total image. The reconstructed image can be viewed through an eyepiece or displayed on a television screen. During the last five years, improved methods of fabricating optical fibers have led to a reduction in fiberscope diameter and an increase in the number of fibers, which in turn has increased resolution. Optical fibers can also be used to deliver laser light. By use of laser beams, physicians can perform surgery inside the body, sometimes eliminating the need of invasive procedures in which healthy tissue must be cut through to reach the site of disease. Many of these procedures do not require anesthesia and can be performed in a physician's office. These techniques have reduced the risk and the cost of medical care.
5. According to the passage, what is the purpose of the illuminating bundle in a fierscope?

Read the following passage and choose the best answer (A, B, C, D):
Egypt’s 100 millionth citizen was born last week, undoubtedly a happy occasion for one family, but a moment filled with foreboding for a country struggling to contain a population explosion. In the past year the government has scrambled to stem the birth rate with a new program called “Two is Enough.” It is establishing family planning clinics throughout the country, where Egyptians can purchase heavily subsidized contraceptives. But many doctors and activists fear that this is too little, and comes too late to reverse the uptick in population growth. Doctors complain that the new “Two is Enough” program lacks in a clear strategy to bring down birthrates. The financial resources deployed thus far have been a fraction of previous efforts; some family-planning clinics have reportedly run out of contraceptives. While clinics funded by the campaign to provide some reproductive health education, sexual education remains taboo in Egyptian schools. There is also a lack of adequate services for the poor and pensioners. Many Egyptians opt to have more children in the hope they will look after them as they age, a phenomenon common in countries with high levels of poverty and inadequate safety nets. While over 30 million Egyptians live in poverty, only 9.4 million receive means-tested cash transfers from the government’s welfare programs. Economic reforms undertaken as part of a recently completed International Monetary Fund program have cut subsidies in a number of areas, contributing a spike in inflation that at one point exceeded 30%. For newborns like the 100-millionth Egyptian, the outlook is grim. A burgeoning population exacerbates many problems. Despite Egypt’s limited supply - it depends almost exclusively on the Nile - there has been a systemic failure to adequately address water waste. From wasteful megaprojects draining the Nile to literally dumping waste in the river, Egyptian officials have consistently failed to prudently protect what is perhaps the country’s most vital natural resource. In 2018, Egypt temporarily reduced the farming of rice, a water intensive crop - only to expand cultivation the following year. The New Administrative Capital that Sisi has set out to erect is projected to need 650,000 cubic meters of water per day when finished. Failure to quickly and dramatically improve water management practices in Egypt could be disastrous, and the risk is the greater for the country’s rapid population growth

Prosthetic body parts have been around in many shapes and forms for thousands of years. But up until just a few decades ago, they were often uncomfortable, provided little to no control for the user and didn’t look all that great either. Fast-forward to the present day and thanks to advances in medicine, robotics and neuroscience, a number of bionic body parts have been developed that have the power to be truly life-changing for those who need them the most, from a bionic eye to an artificial kidney to a thought-controlled robotic leg. Many of these bionic body parts are still in the early stages of production and are far from being rolled out to those that need them. That’s because there are all kinds of challenges to consider – not only the materials the body part is made from, but also integrating it into our bodies so it isn’t rejected, as well as developing ways for it to become part of our nervous system, so it behaves like any other limb or organ. Add to that the huge raft of financial, ethical, moral and political implications of enhancing our bodies with the help of technology. But it’s easy to overlook all of these concerns when the tech sounds so exciting, promising and like the robotic hands, arms and whole bodies of our sci-fi dreams. “The public perception of bionics is vastly different from the reality of prosthetics,” Kia Nazarpour, director of expertise in bio and environmental engineering, at Newcastle University, told us. "That’s thanks to science writers and researchers who showcase their work in a sci-fi oriented way to increase publicity."

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:
At the beginning of the nineteenth century, the American educational system was desperately in need of reform. Private schools existed, but only for the very rich. There were very
few public schools because of the strong sentiment that children who would grow up to be laborers should not “waste” their time on education but should instead prepare themselves for their life’s work. It was in the face of this public sentiment that educational reformers set about their task. Horace Mann, probably the most famous of the reformers, felt that there was no excuse in a republic for any citizen to be uneducated. As Manager of Education in the state of Massachusetts from 1837 to 1848, he initiated various changes, which were soon matched in other school districts around the country. He extended the school year from five to six months and improved the quality of teachers by instituting teacher education and raising teacher salaries. Although these changes did not bring about a sudden improvement in the educational system, they at least increased public awareness as to the need for a further strengthening of the system.

Under certain circumstances, the human body must cope with gases at greater-than-normal atmospheric pressure. For example, gas pressures increase rapidly during a drive made with scuba gear because the breathing equipment allows divers to stay underwater longer and dive deeper. The pressure exerted on the human body increases by 1 atmosphere for every 10 meters of depth in seawater, so that at 39 meters in seawater a diver is exposed to pressure of about 4 atmospheres. The pressure of the gases being breathed must equal the external pressure applied to the body,

otherwise breathing is very difficult. Therefore all of the gases in the air breathed by a scuba diver at 40 meter are present at five times their usual pressure. Nitrogen, which composes 80 percent of the air we breathe, usually causes a balmy feeling of well-being at this pressure. At a depth of 5 atmospheres, nitrogen causes symptoms resembling alcohol intoxication, known as nitrogen narcosis. Nitrogen narcosis apparently results from a direct effect on the brain of the large amounts of nitrogen dissolved in the blood. Deep dives are less dangerous if helium is substituted for nitrogen, because under these pressures helium does not exert a similar narcotic effect.
As a scuba diver descends, the pressure of nitrogen on the lungs increases. Nitrogen then diffuses from the lungs to the blood, and from the blood to body tissues. Nitrogen then diffuses from the lungs to the blood, and from the blood to body tissues The reverse occurs when the diver surfaces, the nitrogen pressure in the lungs falls and the nitrogen diffuses from the tissues into the blood, and from the blood into the lungs. If the return to the surface is too rapid, nitrogen in the tissues and blood cannot diffuse out rapidly enough and nitrogen bubbles are formed. They can cause severe pains, particularly around the joints.
Another complication may result if the breath is held during ascent. During ascent from a depth of 10 meters, the volume of air in the lungs will double because the air pressure at the surface is only half of what it was at 10 meters. This change in volume may cause the lungs to distend and even rupture. This condition is called air embolism.
To avoid this event, a diver must ascend slowly, never at a rate exceeding the rise of the exhaled air bubbles, and must exhale during ascent.

Read the following passage and choose the best answer (A, B, C, D):
Carols were first sung in Europe thousands of years ago, but these were not Christmas Carols. They were pagan songs, sung at the Winter Solstice celebrations as people danced round stone circles. Carols used to be written and sung during all four seasons, but only the tradition of singing them at Christmas has really survived. Early Christians took over the pagan solstice celebrations for Christmas and gave people Christian songs to sing instead of pagan ones. However, not many people liked them as they were all written and sung in Latin, a language that the normal people couldn’t understand. This was changed by St. Francis of Assisi when, in 1223, he started his Nativity Plays in Italy. The people in the plays sang songs or ‘canticles’ that told the story during the plays. Sometimes, the choruses of these new carols were in Latin; but normally they were all in a language that the people watching the play could understand and join in! The new carols spread to France, Spain, Germany and other European countries. The earliest carol, like this, was written in 1410. Sadly only a very small fragment of it still exists. Most Carols from this time and the Elizabethan period are untrue stories, very loosely based on the Christmas story, about the holy family and were seen as entertaining rather than religious songs. They were usually sung in homes rather than in churches! Traveling singers or Minstrels started singing these carols and the words were changed for the local people wherever they were traveling. Before carol singing in public became popular, there were sometimes official carol singers called ‘Waits’. These were bands of people led by important local leaders who had the only power in the towns and villages to take money from the public. Also, at this time, many orchestras and choirs were being set up in the cities of England and people wanted Christmas songs to sing, so carols once again became popular. New carols services were created and became popular, as did the custom of singing carols in the streets. Both of these customs are still popular today! One of the most popular types of Carols services are Carols by Candlelight services. At this service, the church is only lit by candlelight and it feels very Christmassy! Carols by Candlelight services are held in
countries all over the world.

Read the following passage and choose the best answer (A, B, C, D):
The print media includes newspapers, magazines, brochures, newsletters, books and even leaflets and pamphlets. Visual media like photography can also be mentioned under this sub-head, since photography is an important mass media, which communicates via visual representations. Although it is said that the electronic or new media have replaced the print media, there exists a majority of audiences who prefer the print media for various communication purposes. Public speaking and event organizing can also be considered as a form of mass media. For many people, it is impossible to imagine a life without their television sets, be it the daily news dose or even the soap operas. This mass media includes television and radio. This category also included electronic media like movies, CDs and DVDs as well as the new hottest electronic gadgets.  With the advent of new technologies like Internet, we are now enjoying the benefits of high technology mass media, which is not only faster than the old-school mass media, but also has a widespread range. Mobile phones, computers and Internet are often referred to as the new-age media. Internet has opened up several new opportunities for mass communication which include email, websites, blogging, Internet television and many other mass media which are booming today. Mass media was developed as a means of social responsibility at the beginning. However, in the course of time, they have attained the status of an industry. Besides the social and industrial nature of mass media, the following common points may also be mentioned. Specifically, it is highly impersonal, because the masses are not identifiable based on perfectly defined audio, visual or written messages. In addition, it is never likely to reach 100 percent of the target nor to have more than 10 percent effectiveness in most of the cases. Contents are generally based on the broad social issues and aspiration of the target audience which may be designed to achieve some specific goals; and all in all, modern mass media draw heavily on technology

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.

Read the following passage and choose the best answer (A, B, C, D):
Certain birds are, more often than not, considered bad luck, or even a sign of impending death. For example, all over the world, both crows and ravens have some connection to war, and death. In early times, crows and ravens were thought to accompany the gods of war, or be signs of the gods’ approaching arrival. This idea later changed. Crows in particular were thought to be harbingers of ill fortune or, in some cases, guides to the afterlife. Woe be it to the person who saw a single crow or raven flying overhead, for this was most certainly a portent of death in the near future. Interestingly, though potentially bad luck for people individually, the raven is considered to be good luck for the crown of England. So much so, in fact, that a “raven master” is, even today, an actual government position in London. He takes care of the ravens there and also clips their wings, ensuring that these birds can never fly far from the seat of the British government. This way, the kingdom will never fall to ill fortune. Another bird that is thought to play a part in forecasting the fortunes of people is the swallow. Depending on how and when it is seen, the swallow can be a harbinger of either good or ill fortune. Perhaps inspired by the swallow’s red-brown breast, Christian people initially related the swallow to the death of Jesus Christ. Thus, people who saw a swallow fly through their house considered it a portent of death. Later, however, farmers began to consider swallows signs of good fortune. Any barn that has swallows living in it is sure to be blessed in the following year. Farmers also have to beware of killing a swallow; that would be certain to end any good luck they might have had. Though many people think these superstitions are old wives’ tales, there is actually some evidence to support them. For example, crows and ravens, being scavengers, appear at the aftermath of battles. Thus, large numbers of crows and ravens could be good indications of war in an area. As well, swallows feed on insects that can cause infections in cattle. Thus, a farmer who has many swallows in his barn may actually have healthier animals on his farm. Therefore, the next time you feel inclined to laugh at an old wives’ tale, maybe you had better find out if there is any truth to it first!

There is now an increasing (5) _____ for teenagers to mentor young children, for example by helping them with reading or other school work

Read the following passage and choose the best answer (A, B, C, D):
The British are particular about timings and being late is frowned upon, but being on  time is a complicated matter because in some situations, being a few minutes early on others means being exactly on time and in some instances, it is completely acceptable to arrive 10 minutes to a few hours later than the stated time. This can be a minefield for someone who is new to the UK, so here are some basics rules that will help you get your timings right whatever the situation.  In formal meetings, such as job interviews, you should arrive at least five minutes before your meeting. This will give you time to compose yourself before your big meeting. In the UK, arriving late for a formal meeting is seen as unprofessional and will reflect badly on you. If you are running late, ring your host to let them know you will be late. On arrival, apologize sincerely and offer a reason for your lateness, such as you got lost or the train was delayed. It will help you redeem yourself. However, if you are late because you set off later than you should have, it’s wise to keep that to yourself! With appointments such as visits to the doctor or dentist, the time you are given for your appointment isn’t necessarily the time you will be seen. It is not uncommon you may have to wait between 15-30 minutes before you are seen by a doctor and that can be much longer if it is a hospital appointment. Nevertheless, you should arrive at least five minutes before your appointment and it is recommended you take a drink and something to read.  When you start a new job, you are given your typical working hours. For example, if you are expected to start at 9am, it is not acceptable to arrive after this time. Most employers make an exception if you are late once in a while. If you have an appointment, you need to seek permission from your employer to arrive later on that day. Being late consistently will land you in trouble and you can be sacked from your job if after three warnings you are still late.  There is an unsaid rule that you can be a few minutes late for a lecture or seminar once in a while. When you are late, you should enter quietly and find a seat at the back of the room. At the end of lecture or seminar, you should offer your apology to the lecturer. If you have been invited to a dinner party, you should arrive exactly on time as the host will have planned when they will serve the food. You will find that your host will serve their guests a pre-dinner drink, so that gives you a bit of wiggle room, but if you are running later than 10 minutes, you should ring your host and let them know how late you might be. That way they can decide whether to go ahead and serve the other guests. When you arrive you should offer the host and the other guests your apology for being late.

Knowing about the body language of friends, clients, and colleagues can be very helpful in improving understanding and avoiding miscommunication.

Read the following passage and choose the best answer (A, B, C, D):
Vietnam’s population is ageing quickly. In 2017, more than 10 per cent of the population will be 60 and older, and in 15–20 years the elderly will account for one third of the total population. This raises concerns about healthcare, welfare and pensions for the elderly at a time when Vietnam is focusing on economic integration and requires a large labor force. So far two solutions have been proposed: to loosen the two-child policy and to increase the retirement age to 58 for women and 62 for men. By ending the two-child policy the government expects to make up for the ageing population within the next 20 years. But its effect could be creating an uncontrollable boom in the Vietnamese population. When the government loosened the two-child policy in 2015 in a trial period, in the first 6 months of 2016 the third child birth rate increased remarkably by 7.5 per cent. Raising the retirement age has been proposed by the Ministry of Labor pending parliamentary evaluation in May 2017. While the policy is beneficial in utilizing the work experience of the elderly while creating savings in the pension budget, it also means fewer job prospects and promotion opportunities for younger generations. It is also not in the interest of all the elderly, especially the 70 per cent of Vietnam’s labor force working in manual labor-intensive sectors such as agriculture, manufacturing and construction where working above the age of 50 can be dangerous and unproductive. Despite these drawbacks, raising the retirement age is still considered by policymakers as one of the key solutions to the ageing population problem in Vietnam. However, these are only temporary solutions.
