NASA is developing the capabilities needed to send humans to an asteroid by 2025 and Mars in the 2030s – goals outlined in the bipartisan NASA Authorization Act of 2010 and in the U.S. National Space Policy, also issued in 2010. Mars is a rich destination for scientific discovery and robotic and human exploration as we expand our presence into the solar system. Its formation and evolution are comparable to Earth, helping us learn more about our own planet’s history and future. Mars had conditions suitable for life in its past. Future exploration could uncover evidence of life, answering one of the fundamental mysteries of the cosmos: Does life exist beyond Earth? While robotic explorers have studied Mars for more than 40 years, NASA’s path for the human exploration of Mars begins in low-Earth orbit aboard the International Space Station. Astronauts on the orbiting laboratory are helping us prove many of the technologies and communications systems needed for human missions to deep space, including Mars. The space station also advances our understanding of how the body changes in space and how to protect astronaut health. Our next step is deep space, where NASA will send a robotic mission to capture and redirect an asteroid to orbit the moon. Astronauts aboard the Orion spacecraft will explore the asteroid in the 2020s, returning to Earth with samples. This experience in human spaceflight beyond low-Earth orbit will help NASA test new systems and capabilities, such as Solar Electric Propulsion, which we’ll need to send cargo as part of human missions to Mars. Beginning in FY 2018, NASA’s powerful Space Launch System rocket will enable these “proving ground” missions to test new capabilities. Human missions to Mars will rely on Orion and an evolved version of SLS that will be the most powerful launch vehicle ever flown. A fleet of robotic spacecraft and rovers already are on and around Mars, dramatically increasing our knowledge about the Red Planet and paving the way for future human explorers. The Mars Science Laboratory Curiosity Rover measured radiation on the way to Mars and is sending back radiation data from the surface. This data will help us plan how to protect the astronauts who will explore Mars. Future missions like the Mars 2020 rover, seeking signs of past life, also will demonstrate new technologies that could help astronauts survive on Mars. Engineers and scientists around the U.S. are working hard to develop the technologies astronauts will use to one day live and work on Mars, and safely return home from the next giant leap for humanity. NASA also is a leader in a Global Exploration Roadmap, working with international partners and the U.S. commercial space industry on a coordinated expansion of human presence into the solar system, with human missions to the surface of Mars as the driving goal.  
5. The word “capture” in the paragraph 4 could be best replaced by __________

Read the following passage and choose the best answer (A, B, C, D):
In 1988, a year before the Soviet Union collapsed, the 13th National Congress of the  Communist Party of Vietnam adopted a resolution to have “more friends and fewer enemies”. So it was not surprising when Vietnam expressed interest in joining ASEAN as early as 1992, or when it did in fact join in July 1995.   Vietnam’s membership of the grouping integrated its security with the whole of Southeast Asia and created a favourable environment for economic development. This, in turn, raised Vietnam’s global image, leading to increased cooperation with multiple players in the region and greater bargaining clout with super powers like the United States and China. As an ASEAN member, Vietnam has worked hard to secure peace and reconciliation among Southeast Asian nations, which were once deeply divided by war. Vietnam was the first Indochinese country to join ASEAN, and its move helped end confrontation between the Indochinese bloc and ASEAN. Vietnam has also helped ASEAN partner with non-regional players.  Vietnam also led efforts within ASEAN to ensure regional security. Soon after becoming a member, Vietnam signed the Treaty on the Southeast Asian Nuclear-WeaponFree Zone and was one of the founding members of the ASEAN Regional Forum. But the most proactive steps by Hanoi towards regional stability have revolved around disputes in the South China Sea. A direct claimant in the dispute, Vietnam, along with the Philippines, has made constant efforts to put the South China Sea on ASEAN’s agenda, ensuring conflict is dealt with in a constructive way. Vietnam has shown constant support for the Declaration on the Conduct of Parties in the South China Sea, ASEAN’s Six-Point Principles on the East Sea, and the soon-to-be-concluded Code of Conduct of Parties in the East Sea. Vietnam calls for the settlement of disputes by peaceful means on the basis of international law and the 1982 United Nations Convention on the Law of the Sea — including through regulations on respecting exclusive economic zones and the continental shelf of coastal countries. Vietnam has remained committed to ASEAN since it joined in 1995 and Vietnam is beginning to integrate further with the global community, and  cooperation with ASEAN will always be an important pillar in its foreign policy. But Vietnam’s interest in ASEAN is not
limited to security issues. Its leadership also drives efforts toward an ASEAN Economic Community (AEC). 
7. What will the next paragraph of the passage possibly discuss?

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!

Read the following passage and choose the best answer (A, B, C, D):
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.
6. Which of the following can be inferred from the passage?

Read the following passage and choose the best answer (A, B, C, D):
Scientists believe that something very serious is happening to the Earth. It is becoming warmer. Scientists predict that there will be major changes in the climate during the 21st century. Coastal waters will have higher temperatures. This will have a serious effect on agriculture. Farmers will have trouble producing good crops. In warm regions, the weather will be too dry. The amount of water could decrease by 50 per cent. This would cause a large decrease in agricultural production. World temperatures could increase from 1.5 to 5.6 degrees Celsius by the middle of the 21st century. And the increase in temperature could be even greater in the Arctic and Antarctic regions. A rise in temperature could cause the great ice sheets to melt, which, in turn would raise the level of oceans by one to two meters. Many coastal cities would be underwater. Why is all this happening? The Earth and its atmosphere are kept warm by the Sun. The atmosphere lets most of the light from the Sun pass through to warm the Earth. The Earth is warmer by the sunlight and sends heat energy back into the atmosphere. Much of this energy escapes from the Earth’s atmosphere. However, some of it remains. Gases such as carbon dioxide, ozone and water vapor absorb this energy and create more heat. Then, this heat is sent back down to Earth, and the Earth becomes warmer. Recently, however, an increase of carbon dioxide in the atmosphere is causing serious problems. Too much carbon dioxide in the atmosphere prevents heat energy from escaping. Too much heat is sent back down to the Earth, and the amount of carbon dioxide in the atmosphere continues to increase. When oil, gas, and coal burn, they create large amounts of carbon dioxide. The destruction of rain forests that absorb carbon dioxide also helps to increase the amount of carbon dioxide in our atmosphere. Some scientists believe that the amount of carbon dioxide in the air will double by the late 2000s. Scientists call this warming of the Earth and its atmosphere “the greenhouse effect”. A greenhouse, made of glass and plastic, is a special place where plants are grown. The sunlight passes through the glass or plastic and warms the air inside. The heat inside escapes very slowly, so the greenhouse remains very warm. This is exactly what is happening on the Earth. Another reason why the Earth is growing warmer is because of the amount of ozone in our atmosphere. Ozone is a form of oxygen. In the upper atmosphere, very far from the Earth, a layer of ozone helps to protect the Earth from 95 percent of the harmful light that comes from the sun. If your skin receives too much of this light, you would develop skin cancer. We need the ozone layer to protect ourselves. But the ozone layer is in trouble. Scientists have observed that the ozone layer is becoming thin, and above Antarctica there is a hole. This allows too much of the sun’s dangerous light into our atmosphere and makes the Earth warmer. Scientists say we must start making changes and planning now. We need to continue to do research, so we can predict what will happen in the future. We must burn less coal, oil, and gas. Other scientists believe that the problem is not so serious. They think that the Earth is growing warmer naturally, that we don’t need to worry about it now, and that we should just get ready for life in the warmer climate. Most scientists agree that the causes of the world’s climate are very complicated. They say that we must continue to measure the amount of carbon dioxide and ozone in the atmosphere. Scientists also encourage people to learn about the changes that are occurring in the world and how we can all help protect our atmosphere  
3. The melting of the polar ice sheets will probably lead to ____

Read the following passage and choose the best answer (A, B, C, D):
Although the “lie detectors” are being used by governments, police departments, and businesses that all want guaranteed ways of detecting the truth, the results are not always accurate. Lie detectors are properly called emotion detectors, for their aim is to measure bodily changes that contradict what a person says. The polygraph machine records changes in heart rate, breathing, blood pressure, and the electrical activity of the skin (galvanic skin response, or GSR). In the first part of the polygraph test, you are electronically connected to the machine and asked a few neutral questions (“What is your name?”, “Where do you live?”). Your physical reactions serve as the standard (baseline) for evaluating what comes next. Then you are asked a few critical questions among the neutral ones (“When did you rob the bank?”). The assumption is that if you are guilty, your body will reveal the truth, even if you try to deny it. Your heart rate, respiration, and GSR will change abruptly as you respond to the incriminating questions. That is the theory; but psychologists have found that lie detectors are simply not reliable. Since most physical changes are the same across all emotions, machines cannot tell whether you are feeling guilty, angry, nervous, thrilled, or revved up form an exciting day. Innocent people may be tense and nervous about the whole procedure. They may react physiologically to a certain word (“bank”) not because they robbed it, but because they recently bounced a check. In either case the machine will record a “lie”. The reverse mistake is also common. Some practiced liars can lie without flinching, and others learn to beat the machine by tensing muscles or thinking about an exciting experience during neutral questions
2. According to the test, polygraph ________.

Read the following passage and choose the best answer (A, B, C, D):
Perfectly smart adults feel intimidated by numbers and aren’t ashamed to say, “I hate math.” The new book “Math Art” could help change that by making the dreaded topic relevant and accessible to naturalists, artsy types, the philosophically inclined, and committed calculators alike. It illuminates an old lesson your math teachers probably tried to convey when you were a kid: Math dominates our lives even while we try with all our might to ignore it. In Math Art, released in April, science writer Ornes examines creative works inspired by math. It’s an aesthetically pleasing book with a delightfully tactile cover and satisfyingly thick and glossy pages that make it as fun to flip through as a fashion magazine. Chapters are dedicated to different concepts like pi, the golden ratio, equations in nature, and hyperbolic geometry. All of which may sound scary to the uninitiated but gain appeal when illustrated through sculpture, crochet, and painting. As Ornes explains in the introduction, math art isn’t new. Since ancient times, humans have visualized math in creative works. He argues that what is new is the mutual recognition that mathematicians and artists now show each other, increasingly gathering together at events dedicated to the intersection of aesthetics and numbers. “This is art by way of math and math by way of art, beauty at the crossroads,” Ornes writes.  His exploration begins with pi, the irrational mathematical constant 3.14159, plus some, ad infinitum. Pi, the ratio of the circumference of a circle to its diameter, represents mystery itself. Because the sequence never repeats, pi hints at the vastness of the universe. “It speaks to a world without bounds, since its digits go on forever,” Ornes explains. Pi is used for calculations in math and physics, and employed by math artist John Sims to make music, videos, drawings, paintings, quilts, clothing, and stories. Sims created and taught a math curriculum for students at the Ringling College of Art and Design in Sarasota, Florida, and has spent much of his career at the intersection of math and creativity. In Ornes’ book, he explains how he’s also used this fascination to connect with other people he might not otherwise meet, such as the Amish quilters who joined him to make pi quilts with each colored panel representing a number in the mathematical sequence.  
6. According to paragraph 3, what is NOT stated by the author about the Pi number?

If you want to volunteer to help boost your career, think carefully about the skills and  experience you need. Don’t be afraid to be upfront about this when you apply (1)_________ opportunities – as long as you are willing to show commitment to your voluntary work, most organizations will welcome the fact that it could have benefits for you. Volunteering can give you a broad (2) ________ of learning opportunities:  • Many volunteer placements will allow you to study and develop your “key skills”, (3) _________ skills you need to get on in the workplace, in learning and in life.  • Some volunteers receive vocational training in (4) _________ areas such as social care, working with the elderly, or working with children.  • Some roles require specific training such as volunteering as a special constable with your local police force.  The organization you work for usually covers your training costs and expenses in (5) ________ for your time and commitment

Read the following passage and choose the best answer (A, B, C, D):
Like many social and political movements, the green movement has been  strengthened and annealed by the forces that oppose it. After James Watt was appointed to lead the Department of the Interior, for instance, membership in the Sierra Club grew from 183,000 to 245,000 in just 12 months.  Today, the green movement is again defined and galvanized by its command of issues like global warming and climate change, wetlands preservation, the Keystone pipeline, nuclear proliferation, hydraulic fracturing or “fracking,” fisheries depletion, species extinction and other important environmental concerns.  What distinguishes the green movement today from the earlier conservation movement is its emphasis on science and research. Speaking in spiritual tones and using religious metaphors, early environmentalists like Muir and Thoreau celebrated nature for its profound impact on man’s emotions and our souls. When Hetch Hetchy Valley in California was threatened by a dam, Muir exclaimed, “Dam Hetch Hetchy! As well dam for water-tanks the people’s cathedrals and churches, for no holier temple has ever been consecrated by the heart of man.”  Now, however, we are far more likely to call upon scientific data and empirical research to buttress arguments in favor of wilderness preservation, or against polluting industries. Politicians cite the work of polar researchers and use computerized climate models  o battle global warming, and medical researchers rely on public health statistics to argue against mercury pollution. Whether these arguments succeed or fail, however, still depends on the vision, the passion and the commitment of the people who make up the green movement
2. According to paragraph 3, what did Muir’s protest try to express?

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.
1. It took Vietnam about _______ years to move from the poorest to the middle income status?

Read the following passage and choose the best answer (A, B, C, D):
All the different plants and animals in a natural community are in a state of balance. This balance is achieved by the plants and animals interacting (1) _______ each other and with their non-living surroundings. An example of a natural community is a woodland, and a woodland is usually dominated by a particular species of plant, such as the oak tree in an oak wood. The oak tree in this example is therefore called the dominant species but there are also many other types of plants, from brambles, bushes, and small trees to mosses, lichens and algae (2) __________ on tree trunks and rocks. The plants of a community are the producers: they use carbon dioxide, oxygen, nitrogen to build up their tissues using energy in the form of sunlight. The plant tissues form food for the plant-eating animals (herbivores) (3) _______ are in turn eaten by flesh-eating animals (carnivores). Thus, plants produce the basic food supply for all the animals of a community. The animals themselves are the consumers, and are either herbivores or carnivores. Examples of herbivores in a woodland community are rabbits, deer, mice and snails, and insects such as aphids and caterpillars. The herbivores are sometimes eaten by the carnivores. Woodland carnivores are of all sizes, from insects such as beetles and lacewings to animals such as owls, shrews and foxes. Some carnivores feed on herbivores, some feed on the smaller carnivores, (4) _______ some feed on both: a tawny owl will eat beetles and shrews as well as voles and mice. These food relationships between the different members of the community are known as food chains or food (5) ______. All food chains start with plants. The links of the chain are formed by the herbivores that eat the plants and the carnivores that feed on the herbivores. There are more organisms at the base of the food chain than at the top; for example, there are many more green plants than carnivores in a community

Read the following passage and choose the best answer (A, B, C, D):
Many AI researchers roll their eyes when seeing this headline: “Stephen Hawking warns that rise of robots may be disastrous for mankind.” And as many have lost count of how many similar articles they’ve seen. Typically, these articles suggest we should worry about robots rising up and killing us because they’ve become conscious and/or evil. On a lighter note, such articles are actually rather impressive, because they succinctly summarize the scenario that AI researchers don’t worry about. That scenario combines as many as three separate misconceptions: concern about consciousness, evil, and robots. If you drive down the road, you have a subjective experience of colors, sounds, etc. But does a self-driving car have a subjective experience? Does it feel like anything at all to be a self-driving car? Although this mystery of consciousness is interesting in its own right, it’s irrelevant to AI risk. If you get struck by a driverless car, it makes no difference to you whether it subjectively feels conscious. In the same way, what will affect us humans is what superintelligent AI does, not how it subjectively feels. The fear of machines turning evil is another red herring. The real worry isn’t malevolence, but competence. A superintelligent AI is by definition very good at attaining its goals, whatever they may be, so we need to ensure that its goals are aligned with ours. Humans don’t generally hate ants, but we’re more intelligent than they are – so if we want to build a hydroelectric dam and there’s an anthill there, too bad for the ants. The beneficial-AI movement wants to avoid placing humanity in the position of those ants In fact, the main concern of the beneficial-AI movement isn’t with robots but with intelligence itself: specifically, intelligence whose goals are misaligned with ours. To cause us trouble, such misaligned superhuman intelligence needs no robotic body, merely an internet connection – this may enable outsmarting financial markets, out-inventing human researchers, out-manipulating human leaders, and developing weapons we cannot even understand. Even if building robots were physically impossible, a super-intelligent and superwealthy AI could easily pay or manipulate many humans to unwittingly do its bidding. The robot misconception is related to the myth that machines can’t control humans. Intelligence enables control: humans control tigers not because we are stronger, but because we are smarter.  
5. The word “it” in paragraph 2 refers to _____

Rewrite the sentence:
They decided to cut down their carbon footprints. They were praised for that.

Read the following passage and choose the best answer (A, B, C, D):
While family relationships can bring support, joy, and other wonderful benefits into  our lives, these relationships can also bring stress, particularly when there’s unresolved conflict. Because it’s more difficult to let go of conflicted relationships with family than it would be if these relationships were mere friendships, unresolved conflicts with family members can be particularly painful.  We have certain expectations of trust and closeness toward family members, and it can be more than merely disappointing to realize that this may not be possible with all family members. Unresolved family conflicts bring additional stress at family gatherings in particular. Past unresolved conflicts can become the elephant in the room, felt by everyone, but not directly addressed in the situation. This can be stressful for everyone before and during the family gatherings, sometimes leaving a lasting sense of stress afterward as well. Without a heartfelt discussion, an apology or another form of resolution, the trust on both sides is compromised, and may not know what to expect from this person in the future. For example, that one time your mother-in-law criticized your cooking may come up in your mind every time she comes for a visit, and others may sense your tension. This leads many people to assume the worst when they interpret each other’s behavior in the present and future interactions rather than giving the benefit of the doubt as most of us do with people we trust. Also, references or reminders of past conflicts can sting and create new pain.  Once a conflict has gone on a while, even if both parties move on and remain polite, the feelings of pain and mistrust are usually lingering under the surface, and are difficult to resolve: bringing up old hurts in an effort to resolve them can often backfire, as the other party may feel attacked; avoiding the issue altogether but holding onto resentment can poison feelings in the present.  So what do you do at a family gathering when there’s someone there with whom you’ve had an unresolved conflict? Just be polite. Contrary to how many people feel, a family gathering is not the time to rehash old conflicts, as such conversations often get messy before they get resolved — if they get resolved. Again, be polite, redirect conversations that get into areas that may cause conflict, and try to avoid the person as much as you politely can. 
6. Which of the following statements is TRUE, according to the passage?

Read the following passage and choose the best answer (A, B, C, D):
The first two decades of this century were dominated by the microbe hunters. These hunters had tracked down one after another of the microbes responsible for the most dreaded scourges of many centuries: tuberculosis, cholera, diphtheria. But there remained some terrible diseases for which no microbe could be incriminated: scurvy, pellagra, rickets, beriberi. Then it was discovered that these diseases were caused by the lack of vitamins, a trace substance in the diet. The diseases could be prevented or cured by consuming foods that contained the vitamins. And so in the decades of the 1920’s and 1930’s, nutrition became a science and the vitamin hunters replaced the microbe hunters. In the 1940’s and 1950’s, biochemists strived to learn why each of the vitamins was essential for health. They discovered that key enzymes in metabolism depend on one or another of the vitamins as coenzymes to perform the chemistry that provides cells with energy for growth and function. Now, these enzyme hunters occupied center stage. You are aware that the enzyme hunters have been replaced by a new breed of hunters who are tracking genes – the blueprints for each of the enzymes – and are discovering the defective genes that cause inherited diseases – diabetes, cystic fibrosis. These gene hunters, or genetic engineers, use recombinant DNA technology to identify and clone genes and introduce them into bacterial cells and plants to create factories for the massive production of hormones and vaccines for medicine and for better crops for agriculture. Biotechnology has become a multibilliondollar industry. In view of the inexorable progress in science, we can expect that the gene hunters will be replaced in the spotlight. When and by whom? Which kind of hunter will dominate the scene in the last decade of our waning century and in the early decades of the next? I wonder whether the hunters who will occupy the spotlight will be neurobiologists who apply the techniques of the enzyme and gene hunters to the funtions of the brain. What to call them? The head hunters. I will return to them later.
3. Which of the following can be cured by a change in diet?

Eukhtuul smiled, her mother cried, and I had to wipe away some tears, too!’  Now Eukhtuul wants to study hard to become a doctor. Her whole future has changed thanks to a simple operation. We should all think more about how much our sight means to us

It may take place (5) _____individual classrooms or be part of a school-wide activity

Read the following passage and choose the best answer (A, B, C, D):
Many scientists believe our love of sugar may actually be an addiction. When we eat or drink sugary foods, the sugar enters our blood and affects parts of our brain that make us feel good. Then the good feeling goes away, leaving us wanting more. All tasty foods do this, but sugar has a particularly strong effect. In this way, it is in fact an addictive drug, one that doctors recommend we all cut down on. “It seems like every time I study an illness and trace a path to the first cause, I find my way back to sugar,” says scientist Richard Johnson. One- third of adults worldwide have high blood pressure, and up to 347 million have diabetes. Why? "Sugar, we believe, is one of the culprits, if not the major culprit," says Johnson. Our bodies are designed to survive on very little sugar. Early humans often had very little food, so our bodies learned to be very efficient in storing sugar as fat. In this way, we had energy stored for when there was no food. But today, most people have more than enough. So the very thing that once saved us may now be killing us. So what is the solution? It’s obvious that we need to eat less sugar. The trouble is, in today’s world, it’s extremely difficult to avoid. From breakfast cereals to after-dinner desserts, our foods are increasingly filled with it. Some manufacturers even use sugar to replace taste in foods that are advertised as low in fat. But there are those who are fighting back against sugar. Many schools are replacing sugary desserts with healthier options like fruit. Other schools are growing their own food in gardens, or building facilities like walking tracks so students and others in the community can exercise. The battle has not yet been lost.  
4. According to the passage, why is it so hard to avoid sugar?
