NASA continues to plan a flight to Mars. The technological challenge is immense, first  of all, because it will be very difficult to carry tons of material for the construction of a habitat. This is why NASA is looking for alternative solutions, such as the possibility of growing structures out of fungi to become our future homes in the stars. The concept of these “houses” is based on three distinct layers. The first is made of ice. It must protect people from radiation, but also provide the resources necessary for the second layer. This is made of photosynthesizing microbes or cyanobacteria, which produce oxygen for astronauts and nutrients for the final layer of mycelia. That last layer of mycelia is what organically grows into a sturdy home, first activated to grow in a contained environment and then baked to kill the lifeforms.  Researchers have already experimented with creating objects using mycelia. A team from Stanford and Brown universities grew a stool as part of a myco-architecture project at NASA’s Ames research center in 2018. After two weeks of growth, the stool looked like something that would have been long forgotten in a refrigerator. It was then baked that leads to a clean and functional piece of furniture. From the point of view of space conquest, mushrooms could also be used to filter water for future explorers and extract minerals. Once these prototypes are designed for other worlds, we can bring them back to ours. Building this kind of housing could reduce the huge carbon footprint of the construction industry. This research project is still in its infancy, but it shows us how scientists are able to broaden horizons, and it’s exciting.

Read the following passage and choose the best answer (A, B, C, D):
The word noise is derived from the Latin word nausea, meaning “seasickness”. Noise is among the most pervasive pollutants today. Noise pollution can broadly be defined as unwanted or offensive sounds that unreasonably intrude into our daily activities. Noises from traffic, jet engines, barking dogs, garbage trucks, construction equipment, factories, lawn mowers, leaf blowers, televisions, boom boxes and car radios, to name a few, are among the audible litter that is routinely broadcast into the air. One measure of pollution is the danger it poses to health. Noise negatively affects human health and well-being. Problems related to noise include hearing loss, stress, high blood pressure, sleeplessness, fright, distraction, and lost productivity. Noise pollution also contributes to a general reduction in the quality of life and eliminates opportunities for tranquility. We experience noise in a number of ways. On some occasions, we can be both the cause and the victim of noise, such as when we are operating noisy appliances or equipment. There are also instances when we experience noise generated by others, just as people experience secondhand smoke. In both instances, noise is equally damaging physically. Secondhand noise is generally more troubling, however, because it is put into the environment by others, without our consent. The air into which secondhand noise is emitted and on which it travels is “a commons”. It belongs not to an individual person or a group, but to everyone. Please, businesses and organizations, therefore, do not have unlimited rights to broadcast noise the as they please, as if the effects of noise were limited only to their private property. Those that disregard the obligation to not interfere with other’ use and enjoyment of the commons by producing noise pollution are, in many ways, acting like a bully in a schoolyard. Although they may do so unknowingly, they disregard the rights of others and claim for themselves rights that are not theirs. The actual loudness of a sound is only one component of the negative effect noise pollution has on human beings. Other factors that have to be considered are the time and place, the duration, the source of the sound, and even the mood of the affected person. Most people would not be bothered by the sound of a 21-gun salute on a special occasion. On the other hand, the thump-thump of music coming from the apartment downstairs at 2a.m, even if barely audible, might be a major source of stress. The sound of neighbor’s lawn mower may be unobjectionable on a summer afternoon, but if someone is hoping to sleep late on a Saturday morning, the sound of a lawn mower starting up just after sunrise is an irritant

Read the following passage and choose the best answer (A, B, C, D):
Books have been around for thousands of years. When ancient civilizations first started developing writing systems, they would write on just about anything, from stone to tree bark. Ancient Egyptians were the first to use paper-like materials, called “papyrus”, which they made by pounding flat the woven stems of the papyrus plant. It was not long before the ancient Egyptians began gluing together papyrus sheets to form scrolls, which were the first steps toward books as you know. The birthplace of bookbinding is considered to be India in the 2nd century B.C., where Hindi scribes would bind palm leaves that were etched with religious texts between two wooden boards using twine. The technique became popular in the Middle East and Eastern Asia, and spread to the Romans by the 2nd century A.D. In the mid-15th century, German Johannes Gutenberg invented the first mechanical printing press. His invention was revolutionary because it enabled mass production of booksfor the first time. Before the printing press, a few pages per day could be produced by handcopying. Afterward, printing presses could produce as many as 3,600 pages per day. Today, modern publishers take advantage of incredible advances in technology to produce books in many sizes and shapes very quickly. Although there are many types of processes and machines available, most processes involve similar steps. Printers print the text of a book on large sheets of paper, sometimes as large as a newspaper page. Working with large volumes of paper allows printers to lower costs and produce books more efficiently.The large sheets are then cut into smaller pages that are still about twice the size of a finished book. The smaller pages are then divided into small groups, folded in half, and sewn together. Lastly, the folded and sewn pages are cut down to their finished size and glued to the spine of the final book’s cover. Depending on the quality of the book, additional finishing touches may be added, such as blank pages at the front and back of the book or special tape around the edges of the cover to increase durability. Although printed books may never go away completely, today’s readers will most certainly soon become more familiar with e-books. “E-book” refers to an electronic book, which is simply the text of a book displayed electronically, either via the Internet, a CD-ROM, a tablet, an e-book reader, or even a mobile phone. As electronic devices, such as tablets and mobile phones, become more commonplace, e-books are expected to become more and more popular. One of the benefits of e-books is that they save paper, which helps the environment by reducing the demand for trees

Read the following passage and choose the best answer (A, B, C, D):
After World War II drew to a close in the mid-20th century, a new conflict began.  Known as the Cold War, this battle pitted the world’s two great powers–the democratic, capitalist United States and the communist Soviet Union–against each other. By the mid1950s, the U.S.-Soviet Cold War had worked its way into the fabric of everyday life in both countries, fueled by the arms race and the growing threat of nuclear weapons, wide-ranging espionage and counter-espionage between the two countries, war in Korea and a clash of words and ideas carried out in the media. These tensions would continue throughout the space race, exacerbated by such events as the construction of the Berlin Wall in 1961, the Cuban missile crisis of 1962 and the outbreak of war in Southeast Asia. Space exploration served as another dramatic arena for Cold War competition. On October 4, 1957, a Soviet R-7 intercontinental ballistic missile launched Sputnik (Russian for “traveler”), the world’s first artificial satellite and the first man-made object to be placed into the Earth’s orbit. Sputnik’s launch came as a surprise, and not a pleasant one, to most Americans. In the United States, space was seen as the next frontier, a logical extension of the grand American tradition of exploration, and it was crucial not to lose too much ground to the Soviets. In addition, this demonstration of the overwhelming power of the R-7 missile– seemingly capable of delivering a nuclear warhead into U.S. air space–made gathering intelligence about Soviet military activities particularly urgent.  Beginning in the late 1950s, space would become another platform for the competition, as each side sought to prove the superiority of its technology, its military firepower and–by extension–its political-economic system.

People who do not smoke, are not obese, and consume alcohol moderately can expect to live seven years longer than the general population, and to spend most of these extra years in good health, according to a new study published today in Health Affairs. This study was the first to analyze the cumulative impact of several key health behaviours on disability-free and total life expectancy. Previous studies have looked at single health behaviours. Mikko Myrskylä and his colleague instead examined several behaviors simultaneously, which allowed them to determine how long and healthy the lives of people who had avoided most of the well-known individual behavioral risk factors were. The researchers noted that each of the three unhealthy behaviours – obesity, smoking, and unhealthy consumption of alcohol – was linked to a reduction in life expectancy and to an earlier occurrence of disabilities. But there were also differences: smoking was found to be associated with an early death but not with an increase in the number of years with disability, whereas obesity was shown to be associated with a long period of time with disability. Excessive alcohol consumption was found to be associated with both decreased lifespan and a reduced number of healthy years. However, the absence of all of these risky healthy behaviors was found to be associated with the greatest number of healthy years. The most striking finding was the discovery of a large difference in average lifespan between the groups who were the most and the least at risk. Men who were not overweight, had never smoked, and drank moderately were found to live an average of 11 years longer than men who were overweight, had smoked, and drank excessively. For women, the gap between these two groups was found to be even greater, at 12 years. “Our results show how important it is to focus on prevention. Those who avoid risky health behaviours are achieving very long and healthy lives. Effective policy interventions targeting health behaviors could help larger fractions of the population to achieve the health benefits observed in this study,” the researcher emphasized. These results are important not only for individuals, but also for society. In an aging society, the health of the elderly determines the amount of money spent on the health system. In addition, healthy elderly people are better able to participate in the labor market and to perform social roles, such as caring for grandchildren.  
1. What is the best title for the passage?

Read the following passage and choose the best answer (A, B, C, D):
Most languages have several levels of vocabulary that may be used by the same speakers. In English, at least three have been identified and described. Standard usage includes those words and expressions understood, used, and accepted by a majority of the speakers of a language in any situation regardless of the level of formality. As such, these words and expressions are well defined and listed in standard dictionaries. Colloquialisms, on the other hand, are familiar words and idioms that are understood by almost all speakers of a language and used in informal speech or writing, but not considered acceptable for more formal situations. Almost all idiomatic expressions are colloquial language. Slang, refers to words and expressions understood by a large number of speakers but not accepted as appropriate formal usage by the majority. Colloquial expressions and even slang may be found in standard dictionaries but will be so identified. Both colloquial usage and slang are more common in speech than writing. Colloquial speech often passes into standard speech. Some slang also passes into standard speech, but other slang expressions enjoy momentary popularity followed by obscurity. In some cases, the majority never accepts certain slang phrases but nevertheless retains them in their collective memories. Every generation seems to require its own set of words to describe familiar objects and events. It has been pointed out by a number of linguists that three cultural conditions are necessary for the creation of a large body of slang expressions. First, the introduction and acceptance of new objects and situations in the society; second, a diverse population with a large number of subgroups; third, association among the subgroups and the majority population. Finally, it is worth noting that the terms "standard", "colloquial", and "slang" exist only as abstract labels for scholars who study language. Only a tiny number of the speakers of any language will be aware that they are using colloquial or slang expressions. Most speakers of English will, during appropriate situations, select and use three types of expressions.

Carefully guiding a needle that's longer than his tiny fingers, a young boy in Pakistan stitches together the leather pieces of a soccer ball. He sits crouched in the corner of a hot, airless shed for 12 hours. For his long day's work, he will earn 60 cents.
The boy is one of more than 200 million children who work at hard, sometimes dangerous jobs all over the world. Child labor exists in two-thirds of the world's nations. From Indonesia to Guatemala, poor children as young as six are sent off to work. Often they are mistreated and punished for not working hard enough. Children mix the gunpowder for firecrackers in China and knot the threads for carpets in India, all for pennies a day. Sometimes they are sold as slaves.
In a speech to the Child Labor Coalition when he was U.S. Secretary of Labor, Robert Reich expressed gratitude for the organization's work to end abuse of child labor, "You turned up the heat, and you got results." He also congratulated Craig Kielburger, then 13, of Canada, who traveled the world for a year fighting for kids' rights. Craig believes kids can make a difference. He offers this advice, "Write letters to companies and government officials. Put pressure on leaders to make changes and to stop the misuse of children."
One solution to the child-labor problem in poor countries is education. "The future of these countries," Secretary Reich declared, "depends on a work force that is educated. We are prepared to help build schools."
Education has helped to make the world a brighter place for one youth, Aghan of India. When he was nine, Aghan was kidnapped from his home and sold to a carpet maker. Aghan's boss was very cruel. "I was always crying for my mother," he recalls. Aghan's dream was to learn to write so that he could send letters to his parents. Fortunately, a group that opposes child labor rescued Aghan from the factory. He was sent to a shelter in New Delhi where he worked hard to learn to write.

The poaching crisis wiping out Africa's elephants is costing the continent's economies millions in lost tourism revenue, according to a new study. Researchers looked at visitor and elephant data across 25 countries, and modeled financial losses from fewer visitors in protected areas due to the illegal wildlife trade, which has caused elephant numbers to plummet by more than 100,000 in the last decade. (A)

The study team combined visitor numbers across 164 protected areas in 25 countries in forest and savannah elephants, and elephant population data from 2009 to 2013, to reach a “per elephant" value in terms of tourism income.

They concluded that Africa was most likely losing $26m in tourism revenue a year. (B) Around $9m of that is lost from tourists' direct spending, such as staying at hotels and buying crafts, with the rest through indirect value in the economy such as farmers and other suppliers supporting the tourist industry.

The study, published in the journal Nature Communications, found that in most cases the revenue losses were higher than paying for stronger anti-poaching measures to keep elephant populations stable. (C) Dr. Robin Naidoo, the paper's lead author and , senior conservation wildlife scientist at WWF and his team found. In the case of central Africa's forest elephants, which are harder for tourists to see and therefore attract fewer visitors, the costs of protecting them exceed the benefits from tourism. Demand from south-east Asia has seen the price of ivory triple since 2009 and it is estimated that one elephant is killed every 15 minutes. (D) Corruption, a lack of resources, and, most importantly, increasingly sophisticated poachers have hamstrung African countries' efforts to stem the trade.

Naidoo said that the research was not suggesting economic issues should be the only consideration when protecting elephants, but framing the poaching crisis as a financial one could motivate African governments and communities.

“It gives an additional reason for some groups of people, who may not necessarily be motivated by intrinsic reasons for conversation, to engage with biodiversity conservation. It makes it clear to them that it's not just in the best interests of the world to conserve this stuff, but tangible reasons for a whole different group," he said.

The overall profit that the continent lost a year can be estimated to ____.

We live in a world of tired, sleep deprived people. In his book Counting Sheep, Paul Martin - a behavioral biologist - describes a society which is just too busy to sleep and which does not give sleeping the importance it deserves. Modern society has invented reasons not to sleep. We are now a 24/7 society where shops and services must be available all hours. We spend longer hours at work than we used to, and more time getting to work. Mobile phones and email allow us to stay in touch round the clock and late-night TV and the Internet tempt us away from our beds. When we need more time for work or pleasure, the easy solution is to sleep less. The average adult sleeps only 6.2 hours a night during the week, whereas research shows that most people need eight or even eight and a half hours’ sleep to feel at their best. Nowadays, many people have got used to sleeping less than they need and they live in an almost permanent state of “sleep debt”.  Until the invention of the electric light in 1879 our daily cycle of sleep used to depend on the hours of daylight. People would get up with the sun and go to bed at nightfall. But nowadays our hours of sleep are mainly determined by our working hours (or our social life) and most people are woken up artificially by an alarm clock. During the day caffeine, the world’s most popular drug, helps to keep us awake. 75% of the world’s population habitually consume caffeine, which up to a point masks the symptoms of sleep deprivation. What does a chronic lack of sleep do to us? As well as making us irritable and unhappy as humans, it also reduces our motivation and ability to work. This has serious implications for society in general. Doctors, for example, are often chronically sleep deprived, especially when they are on “night call”, and may get less than three hours’ sleep. Lack of sleep can seriously impair their mood, judgment, and ability to take decisions. Tired engineers, in the early hours of the morning, made a series of mistakes with catastrophic results. On our roads and motorways lack of sleep kills thousands of people every year. Tests show that a tired driver can be just as dangerous as a drunken driver. However, driving when drunk is against the law but driving when exhausted isn’t. As Paul Martin says, it is very ironic that we admire people who function on very little sleep instead of criticizing them for being irresponsible. Our world would be a much safer, happier place if everyone, whatever their job, slept eight hours a night  
7. Which of the following would the writer of the passage approve of?

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.

Animation traditionally is done by hand-drawing or painting successive frame of an object, each slightly different than the proceeding frame. In computer animation, although the computer may be the one to draw the different frames, in most cases the artist will draw the beginning and ending frames and the computer will produce the drawings between the first and the last drawing. This is generally referred to as computer-assisted animation, because the computer is more of a helper than an originator.

In full computer animation, complex mathematical formulas are used to produce the final sequences of pictures. These formulas operate on extensive databases of numbers that defines the objects in the pictures as they exist in mathematical space. The database consists of endpoints, and color and intensity information. Highly trained professionals are needed to produce such effects because animation that obtains high degrees of realism involves computer techniques from three-dimensional transformation, shading, and curvatures.

High-tech computer animation for film involves very expensive computer systems along with special color terminals or frame buffers. The frame buffer is nothing more than a giant image memory for viewing a single frame. It temporarily holds the image for display on the screen.

A camera can be used to film directly from the computer’s display screen, but for the highest quality images possible, expensive film recorders are used. The computer computers the positions and colors for the figures in the picture, and sends this information to the recorder, which captures it on film. Sometimes, however, the images are stored on a large magnetic disk before being sent to the recorder. Once this process is completed, it is replaced for the next frame. When the entire sequence has been recorded on the film, the film must be developed before the animation can be viewed. If the entire sequence does not seem right, the motions must be corrected, recomputed, redisplayed, and rerecorded. This approach can be very expensive and time – consuming. Often, computer-animation companies first do motion tests with simple computer-generated line drawings before selling their computers to the task of calculating the high-resolution, realistic-looking images.

Which of the following statement is supported by the passage?

Read the following passage and choose the best answer (A, B, C, D):
You’ll be able to purchase high-quality emotions online. Emotion-sharing experiences  are the latest fad in 2045. Imagine your friend at Glastonbury can post a photo on Instagram and with it comes bundled a faint twinkling of what she was feeling right there in that moment, so you too can share emotionally in her social experience.  Recently, techniques for direct brain stimulation, like opt genetics, have made it possible to not only read but also write information into single neurons. At the moment data transfer rates are still very slow, the best we can do is a few bits per second, but this could well increase to kilobits or maybe reach broadband speeds by 2045. This means the range of human perception could expand beyond its current design limitations. One could foresee a new and extraordinary world where there is a virtual marketplace for trading high quality emotions – where artists looking for a particularly high strength brew of melancholy, or actors needing to channel regret or compassion for their next play, could purchase emotions online.  Our cities will be made from living, dynamic materials that respond to the environment. In 30 years, tall buildings made of glass and twisted steel will be seen as relics from a bygone era, in the same way we think now of 1970s concrete tower blocks: ugly, outdated and unfit for contemporary purpose. The urban environment of 2045 blends architecture with living materials that are mouldable, adaptable, responsive and disposable.  Entirely new synthetic life forms, or biological machines, made of engineered living cells from bacteria, fungi and algae will grow and evolve with the changing needs of a building’s inhabitants. They breathe in pollutants, clean wastewater, and use sunlight to make useful chemicals, energy, heat and vibrant vertical gardens. We will start to see a convergence between biology and technology, to the point where there is no longer a perceptible difference between the two. Today, synthetic biology labs are looking at the full diversity of what nature has to offer and using this to mix, match and edit genomes to design synthetic life forms. Right now, this field is just getting started and the science of synthetic biology is going to be tougher than most will admit.  We will use invisibility cloaks to “disappear” ugly objects. Invisibility has forever been a tantalizing prospect. The key to cloaking lies in the way the electromagnetic spectrum  (including visible light) interacts with objects. The human eye picks up electromagnetic radiation that falls and scatters from objects and we perceive this as light. In recent decades, scientists figured out using mathematics that it might just be possible to imagine a new class of artificial materials made of intricate tiny features with light bending properties. They named them metamaterials.  Using nanotechnology engineering, scientists have since shown cloaking actually works – in principle at least, for a narrow range of colours and only from certain viewing angles. The future applications of cloaking are highly uncertain and will likely be determined by the fads and social contagion of the time. They may be used in everything from novelty gimmicks to making unsightly construction sites and power stations seemingly ‘disappear’.

Diseases are a natural part of life on earth. If there were no diseases, the population would grow too quickly, and there would not be enough food or other resources, so in a way, diseases are natural ways of keeping the Earth in balance. But sometimes they spread very quickly and kill large numbers of people. For example, in 1918, an outbreak of the flu across the world, killing over 25 million people only in six months. Such terrible outbreaks of a diseases are called pandemics. Pandemics happen when a disease changes in a way that our bodies are not prepared to fiht. In 1918, a new type of fl virus appeared. Our bodies had no way to fiht this new flu virus, and so it spread very quickly and killed large numbers of people. While there have been many different pandemic diseases throughout history, all of them have a new thing in common. First, all pandemic diseases spread from one person to another very easily. Second, while they may kill many people, they generally do not kill people very quickly. A good example of this would be the Marburg virus. The Marburg virus is an extremely infectious disease. In addition, it is deadly. About 70%-80% of all people who get the Marburg virus died from the disease. However, the Marburg virus has not become a pandemics because most people die within three days of getting the disease. This means that the virus does not have enough time to spread a large number of people. The flu virus of 1918, on the other hand, generally took about a week to ten days to kill its victims, so it had more time to spread. While we may never be able to completely stop pandemics, we can make them less common. Doctors carefully monitor new disease that they fear could become pandemics. For example, in 2002, and 2003, doctors carefully watched SARS. Their health warming may have prevented SARS from becoming a pandemic.

Climate change, also called global warming, refers to the rise in average surface temperatures on Earth. An overwhelming scientific consensus maintains that climate change is due primarily to the human use of fossil fuels, which (1) __________ carbon dioxide and other greenhouse gases into the air. The gases trap heat within the atmosphere, which can have a range of effects on ecosystems, (2) __________ rising sea levels, severe weather events, and droughts that render landscapes more susceptible to wildfires. While consensus among nearly all scientists, scientific organizations, and governments is (3)__________ climate change is happening and is caused by human activity, a small minority of voices questions the validity of such assertions and prefers to cast doubt on the preponderance of evidence. Climate change deniers often claim that recent changes (4) __________ to human activity can be seen as part of the natural variations in Earth’s climate and temperature, and that it is difficult or impossible to establish a direct connection between climate change and any single weather event, such as a hurricane.

Hidden beneath the waves of the Tyrrhenian Sea near southwestern Italy lies a newfound volcanic mosaic dotted with geothermal chimneys and flat-topped seamounts. This complex is new to both science and the planet, geologically speaking; it’s only about 780,000 years old. Scientists aren’t particularly surprised to find volcanism in the region, which is home to active volcanoes like Mount Vesuvius and Mount Etna. But the new complex is unusual because it was created by a rare kind of fault, said study leader Fabrizio Pepe. The western Mediterranean is seismically restless because of the collision of three tectonic plates: the African, the Eurasian and the Anatolian. Making matters more complex is a small chunk of crust called the Adriatic-Ionian microplate, which broke off of the African Plate more than 65 million years ago and is now being pushed under the larger Eurasian Plate in a process called subduction. Previously, scientists discovered a series of undersea volcanic arcs created by this tectonic unrest, starting near the Sardinian coast, with increasingly younger arcs southward and eastward. These arcs were like an arrow pointing ever farther eastward, prompting Pepe and his colleagues to search for an even younger arc about 9 miles off the coast of Calabria. There, based on seafloor mapping, seismic data and magnetic anomalies, the researchers found a 772-square-mile region of lava flows, volcanic mountains and hydrothermal chimneys; vents in the seafloor allow hot minerals to spew out and form chimney-like structures. They dubbed the new area the Diamante‐Enotrio‐Ovidio Volcanic‐Intrusive Complex, after three flat-topped seamounts that dominate the seafloor. Those fractures are what allowed magma to rise to the surface at the Diamonte-EnotrioOvidio complex, creating an undersea landscape of lava flows and mountainous volcanoes. These volcanic seamounts are now plateaus because they protruded from the ocean when the sea level was lower, and they eroded into their present, flat-topped shape, Pepe said. The volcanic complex is inactive, but there are small intrusions of lava in some parts of the seafloor there. However, the area could become active in the future, Pepe said, and active volcanism is ongoing on the eastern side of the Tyrrhenian Sea. The researchers are working to build a volcanic risk map of the complex to better understand if it could endanger human life or property. They are also investigating the possibility of tapping the complex to produce geothermal energy.

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.”
