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.

Lead researcher on the atlas, Dr Zoë Randle, said the northerly migration of species of moths and butterflies is a phenomenon observed in northern Europe in recent decades. She said moths are proof that human-made climate change is happening now. Great Britain has observed the arrival of new species too, such as the Clifden Nonpareil, Tree-lichen Beauty and Black-spotted Chestnut. The atlas records that 38 per cent of all moth species in Britain and Ireland have spread to other areas in the last 50 years, most as a result of global warming. The book lists 893 species in all and the scientists’ analysis of distribution records over the period 1970-2016 in particular showed that 31 per cent of 390 larger moth species decreased significantly in Britain. Intensive agriculture has caused the decline of many moth species through the destruction of wildlife-rich habitats and use of fertilizers and pesticides. Widespread environmental pollution such as artificial light at night and chemicals in the air and soil, are altering plant and animal communities in ways that are still not fully understood. Humanmade climate change has facilitated the spread of moths to new parts of Britain and Ireland that were formerly too cold, while at the same time posing a long-term risk to species found in cool and restricted habitats such as mountainsides. The atlas is based on more than 25 million records sourced from Butterfly Conservation’s National Moth Recording Scheme and the Moths Ireland database. These date from the 18th century through to 2016, meaning this volume contains 275 years of mothrecording effort by the public. Dr Randle said the same system of comprehensive recording is not yet available in Ireland as it is in Britain, but anecdotally she believes the same patterns are emerging in Ireland.  
2. According to paragraph 1, the following statements are true about the migration of moths, EXCEPT _______

It’s important to be able to articulate your dream job. Not just for personal reasons,  but also for when you’re asked about it in interviews. But, how can you even begin to describe your ideal job, especially to someone who’s clearly going to be judging your response? Just picking a place to start is a head-scratcher.  First, let’s talk about what you’re good at doing, or your strengths. It’s likely you’ve already had the chance to talk about this topic a bit during the interview, so it makes for a nice transition. Highlight the skills that you enjoy using most, not just the ones you’re a superstar at. This is about your dream job, so don’t shy away from mentioning any that you want to grow as well.  Think big picture for this. What drew you to your industry? What’s something you did as a kid that’s actually found its way into your work? What is it about your career that keeps you engaged? Weave that in. Giving a sense of what your career values are will give the interviewer an idea about what motivates you; it’s a good way to bring the focus back to the company you’re interviewing for. It also adds some extra complexity to your answer. You’re not just saying, “I want an interesting job that I’m good at.” I mean, that’s nice, but this is your dream job we’re talking about! Don’t pigeonhole yourself with anything that official. Instead, give the hiring manager a more nuanced response by covering your skills, interests, and values. He or she will get the chance to learn more about you—and you have more flexibility to line up your career goals and the position you’re applying for. That’s a win-win.

Dr. Daniel Quon has been an oral surgeon in Jackson for over 30 years. “Growing up  in the family business, I knew that in order for you to gain something, you have to give back,” Quon said. “And being in the field of dentistry, we have a special gift that we can help people and I thought that was an appropriate way to help out.”  Quon volunteers his dental services at the Jackson Free Health Clinic to patients who can’t afford it. Through the Mississippi Dental Association, Quon also provides free dental care for the Mission Service of Mercy program. Dental Assistant Carley Welch has been a part of this experience. “We actually did that last year together and we plan on doing that again this year together,” he said. “Best boss you can ask for,” Welch continued. “Very patient, always willing to teach you; even things that most people wouldn’t go very far to teach you, he will. Just so you have the experience.” But Quon serves in other ways too. “Wife and I volunteer at the Stewpot. We serve lunch on Saturdays when we can. I was actually on the board of Stewpot for 3 years until this passed year.” And he donates blood platelet at the Mississippi Blood services. “I’m almost up to 18 gallons right now in donations. That’s a lot of blood! still got a little bit left though.” “It takes very little time to volunteer. It’s a great thing where you can help someone who needs an extra hand or helping hand.” “I think he does his part to contribute as much as possible,” Welch added. “Whether it’s helping dental wise or even just in general with the public.”

From their inception, most rural neighborhoods in colonial North America included at least one carpenter, joiner, sawyer, and cooper in woodworking; a weaver and a tailor for clothing production; a tanner, currier, and cordwainer (shoemaker) for fabricating leather objects; and a blacksmith for metalwork. Where stone was the local building material, a mason was sure to appear on the list of people who paid taxes. With only an apprentice as an assistant, the rural artisan provided the neighborhood with common goods from furniture to shoes to farm equipment in exchange for cash or for “goods in kind” from the customer’s field, pasture, or dairy. Sometimes artisans transformed material provided by the customer wove cloth of yam spun at the farm from the wool of the family sheep; made chairs or tables from wood cut in the customer’s own woodlot; produced shoes or leather breeches from cow, deer, or sheepskin tanned on the farm.  Like their farming neighbors, rural artisans were part of an economy seen, by one historian, as “an orchestra conducted by nature.” Some tasks could not be done in the winter, others had to be put off during harvest time, and still others waited on raw materials that were only produced seasonally. As the days grew shorter, shop hours kept pace, since few artisans could afford enough artificial light to continue work when the sun went down.  To the best of their ability, colonial artisans tried to keep their shops as efficient as possible and to regularize their schedules and methods of production for the best return on their investment in time, tools, and materials. While it is pleasant to imagine a woodworker, for example, carefully matching lumber, joining a chest together without resort to nails or glue, and applying all thought and energy to carving beautiful designs on the finished piece, the time required was not justified unless the customer was willing to pay extra for the quality - and few in rural areas were. Artisans, therefore, often found it necessary to employ as many shortcuts and economics as possible while still producing satisfactory products.
2. The word “inception” in the passage is closest in meaning to ____

Read the following passage and choose the best answer (A, B, C, D):
An integral part of human life is the sports. As we all know, many competitive and  entertaining activities are engaged in sports. A sport is a way to stay fit and healthy. If we want to be physically fit we have to have an active life to stay healthy, so it is always a good idea to participate in sports and games.  The sport has inherent discipline and physical demands so that enthusiasts tend to maintain a healthy lifestyle. Weight loss, more energy, better mobility and a lot of things can come from the sport. All of this can describe a good person’s health. People are taught by sports and games to appreciate their health. The energy and vitality necessary to participate cannot be sustained without health. For professional athletes, their fitness and health depend on their livelihood. Sport also aims to keep individuals in good health and endurance.  Water is the most important nutrient that we cannot live without. If you do sports, you tend to sweat more thus increase your metabolic rate. If you do not replace these fluids, you can have very serious health problems or you can even die. To have a healthy and active body we need to eat essential nutrients. Participating in sports activities will encourage you to drink more water since we develop the urge to do so when we participate in physical activities.  When participating in sports activities we come to learn new things. It makes us learn how to tackle things the difficult situation. Sports develop a sense of unity and brotherliness. It develops team spirit in us. It helps in developing mental and physical toughness. It improves our efficiency. With our day-in-day-out activities, we tend to become exhausted the more reason we need sports in our lives to help us forget stressful things we go through. Everybody should always play a sport once a week to keep themselves fit and healthy. Sport is a fundamental phase for a child who is learning. In education, it helps the students keep their value in life, students are taught various games in the very early stage of life at school. Nurturing sports talents from school encourages a lot of talented children and it affirms the sportsmanship in them. Those students who perform well are promoted to play at the national and international level. Sports can be a carrier developing option for many students.  As we know, a physical activity governed by a set of rules or habits is called sport. Sport is often involved in the competition. The sport was originally developed for recreation. When people want to do the distraction or recovery, they usually do sports, sports games or skill tests. From this, we can conclude that sport has large and varied manifestations.  Sport can be played indoors or outdoors. It can be done by individual or team, with or without competition. And we know that sport requires skill and physical effort. The growth and development of sport and its related industries were witnessed by modern sport. Because we know that a healthy person is a wealthy person, the sport is the secret of both health and prosperity.

There are three valid arguments to support the preservation of endangered species. An aesthetic justification contends that biodiversity contributes to the quality of life because many of the endangered plants and animals are particularly appreciated for their unique physical beauty. The aesthetic role of nature in all its diverse forms is reflected in the art and literature of every culture, attaining symbolic status in the spiritual life of many groups. According to the proponents of the aesthetic argument, people need nature in all its diverse and beautiful forms as part of the experience of the world.
Another argument that has been put forward, especially by groups in the medical and pharmacological fields, is that of ecological self-interest. By preserving all species, we retain a balance of nature that is ultimately beneficial to humankind. Recent research on global ecosystems has been cited as evidence that every species contributes important or even essential functions that may be necessary to the survival of our own species. Some advocates of the ecological argument contend that important chemical compounds derived from rare plants may contain the key to a cure for one of the diseases currently threatening human beings. If we do not protect other species, then they cannot protect us.
Apart from human advantage in both the aesthetic and ecological arguments, the proponents of a moral justification contend that all species have the right to exist, a viewpoint stated in the United Nations World Charter for nature, created in 1982. Furthermore, if humankind views itself as the stewards of all the creatures on Earth, then it is incumbent upon human beings to protect them, and to ensure the continued existence of all species. Moral justification has been extended by a movement called “deep ecology,” the members of which rank the biosphere higher than people because the continuation of life depends on this larger perspective. To carry their argument to its logical conclusion, all choices must be made for the biosphere, not for people.

The author mentions all of the following as justifications for the protection of endangered species EXCEPT    .

Electronic devices are becoming increasingly common in educational environments. The term most commonly used for such devices is “educational technology”. This is not actually a new idea, as the rewritable wax tablets, often with lined surfaces to guide novice writers used in antiquity or the blackboard itself are both instances of technological innovations to support pedagogy. There are many different ways in which electronic devices are used in education. For example, students in STEM (science, technology, engineering medicine) fields have been making extensive use of sophisticated calculators for many years (the abacus and slide rule were non-electronic predecessors to calculators). In humanities as well as sciences, students use computers or equivalent devices to do research and write papers. In all fields, courses are now likely to have websites, and many instructors use course management software such as Blackboard, to post information for students, record grades, set up online discussions, and check for plagiarism. In lecture classes, many instructors project slides or notes on a screen and may even upload lecture notes so that students can review them. Some courses are hybrid, meaning that they have a strong online component, or offered entirely online. Many courses taught in conventional lecture halls are streamed online, and may use devices such as clickers to become more interactive. Any device (including tablets or cell phones) that instructors incorporate into a learning environment functions as educational technology.  
1. According to the passage, the term “educational technology” refers to ____

Read the following passage and choose the best answer (A, B, C, D):
The world is losing languages at an alarming rate. Michael Krauss suggested that of the approximately 6,000 human languages alive today, only 350 to 500 are safe from extinction. Some linguists estimate that a language dies every two weeks or so. At the current rate, by 2100, about 2,500 native languages could disappear. Languages become extinct for many reasons. Through imperialism, colonizers impose their languages on colonies. Some politicians believe multilingualism will fragment national interests. Thus they prohibit education in all but the national language. Another reason for language death is the spread of more powerful languages. In the world today, several languages, including English, are so dominant in commerce, science, and education, that languages with fewer speakers have trouble competing. Although in the past, governments have been one of the primary causes of language death, many have now become champions of preserving endangered languages and have had some significant successes. Two outstanding examples are the revival of Hebrew and Irish. Hebrew was considered a dead language, like Latin, but is now the national language of Israel. Irish was not dead, but severely threatened by English when the government of Ireland began its rescue immediately after the establishment of the Irish Free State in 1922. All students in public schools must now take some classes in Irish and there are Irish programs in major media, such as television and radio. According to the Irish government, approximately 37% of the population of Ireland now speaks Irish. One of the largest programs to revive languages, Documenting Endangered Languages (DEL), is being conducted by three U.S. government agencies: the National Science Foundation, the National Endowment for the Humanities, and the National Museum of Natural History. Researchers funded by these agencies are recording interviews with the mostly elderly people who still speak the languages. Analyses of these interviews will help linguists publish dictionaries and grammars of the languages. Eventually, linguists hope to establish language-training programs where younger people can learn the languages, carrying them on into the future. The linguists participating in DEL defend spending millions of dollars to preserve dying languages. They point out that when a language dies, humanity loses all of the knowledge of the world that that culture held. Traditional healers in rural areas have given scientists important leads in finding new medicines; aspirin is an example of these. But one of the most common reasons given by these researchers is that studying languages gives us insight into the radically different way humans organize their world. David Lightfoot, an official at the National Science foundation, gives the example of Guguyimadjir, and Australian aboriginal language, in which there are no words for “right” or left,” only for “north,” “south,” “east,” and “west.” Many researchers are optimistic that the efforts to save dying languages will succeed, at least in part. Bruce L. Cole, Chairman of the National Endowment for the Humanities, said, “Not only is this a time of great potential loss, it is also a moment for enormous potential gain. In this modern age of computers and our growing technological capabilities, we can preserve, assemble, analyze, and understand unprecedented riches of linguistic and cultural information.”

Anna Gomez is a successful TV sports presenter, but most people still think of her as the famous women’s ice-skating champion who won several important competitions when she was younger. “As a child, my dream was actually to become a ballet dancer – I didn’t own any skates until I was nine, and didn’t become really keen on skating until I was fourteen,” says Anna. She went on to university, where, despite ice-skating almost all the time, she left with an excellent degree. “I felt I owed it to my parents. They supported me through university, and expected me to do well there – I didn’t feel I could disappoint them.” In a sport where most stars become famous as teenagers, Anna was unusual in being in her twenties before she won any major titles. “When I was younger, I got very angry at competitions, shouting at judges if I disagreed with them. That made me unpopular, especially with other skaters. My technique was just as good as theirs and I had a very encouraging coach at the time. The problem was in my head – I just didn’t think I had what it takes to be a champion. That changed as I won more competitions, and I was performing at my best by the age of twenty-five.” Anna retired from professional ice-skating five years later, having accomplished great success during that period. “It was a difficult decision. As you get near the end of your career, people always ask when you’re going to stop. At the time, I wasn’t sure that I was actually ready to give up. But, looking back, I’m glad I stopped when I did. You shouldn’t think too much about the past – just move on to the next thing.”

“I am sorry but I won’t do the extra work,” Carol said.

Read the following passage and choose the best answer (A, B, C, D):
During droughts water is scarce but is it possible to make it rain to provide water. Experiments in cloud seeding suggest that it may be possible to artificially create rainfall. Rainfall occurs when supercooled droplets of water – those that are still liquid but are at a temperature below the usual freezing point of zero centigrade – form ice crystals. Now too heavy to remain suspended in the air, these then fall, often melting on their way down to form rain. Even in dry areas the air usually contains some water. This can be made to come together and form ice crystals by seeding the atmosphere with chemicals such as silver iodide or dry ice. They work to promote rainfall by inducing nucleation – what little water is in the air condenses around the newly introduced particles and crystallises to form ice. The ‘seeds’ can be delivered by plane or simply by spraying from the ground. But does it work? It’s hard to tell for sure. As is often the case with weather and climate, it’s impossible to carry out a controlled experiment – so, in areas of increased precipitation, we can’t know whether it would still have rained even if the clouds hadn’t been seeded. Success has been claimed for trials in Australia, France, Spain and the US. In the United Arab Emirates, the technique is credited with the creation of 52 storms in the Abu Dhabi desert, while China boasts of having used the technology in reverse to keep the Beijing Olympic Games of 2008 dry. Recent research, however, suggests that it’s not as effective as was previously believed

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.  
8. Which of the following can be inferred from the passage?

Read the following passage and choose the best answer (A, B, C, D):
Aging is the process of growing old. It occurs eventually in every living thing provided, of course, that an illness or accident does not kill it prematurely. The most familiar outward signs of aging may be seen in old people, such as the graying of the hair and the wrinkling of the skin. Signs of aging in a pet dog or cat include loss of playfulness and energy, a decline in hearing and eyesight, or even a light graying of the coat. Plants are too, but the signs are much harder to detect. Most body parts grow bigger and stronger, and function more effiiently during childhood. They reach their peak at the time of maturity, or early adulthood. After that, they begin to decline. Bones, for example, gradually become lighter and more brittle. In the aged, the joints between the bones also become rigid and more inflxible. This can make moving very painful. All the major organs of the body show signs of aging. The brain, for example, works less effiiently, and even gets smaller in size. Thinking processes of all sorts are slowed down. Old people often have trouble in remembering recent events. One of the most serious changes of old age occurs in the arteries, the blood vessels that lead from the heart. They become thickened and constricted, allowing less blood to flw to the rest of body. This condition accounts, directly or indirectly, for many of the diseases of the aged. It may, for example, result in heart attack. Aging is not a uniform process. Different parts of the body wear out at the different rates. There are differences among people in their rate of aging. Even the cell of the body differ in the way they age. The majority of cells are capable of reproducing themselves many times during the course of a lifetime. Nerve cells and muscle fiers can never be replaced once they wear out. Gerontologists - scientists who study the process of aging - believe this wearing out of the body is controlled by a built-in biological time-clock. They are trying to discover how this clock works so that they can slow down the process. This could give man a longer life and a great number of productive years.

Read the following passage and choose the best answer (A, B, C, D):
In all the debate about conservation of natural landscapes, we must not forget that the 19th century also saw the development of interest in the cultural past. Although archaeology was around 100 years old at this point, at least in the Old World, it was largely an exercise in treasure hunting - digging up the treasures of the past as curiosities for museums or for the private collections of those who funded the dig. Changes in attitudes and law throughout the 19th century meant that monuments and artefacts were becoming part of the study of the past, no longer merely trinkets and curiosities, but indicators of a culture’s development and identity. Modern archaeology would not arrive until the 20th century and the concept of an archaeological landscape is younger still. The first laws to protect and conserve cultural heritage came into place in the late 19th and early 20th centuries in the developed countries. In the US, the first such law was the Antiquities Act in 1906 which gave the office of president the power to set aside areas of land as protected cultural assets, known as “National Monuments”. This law was in place until 1979 when it was replaced with the Archaeological Resources Protection Act but several other laws came into place before then that  required archaeologists to label and give proper contexts to monuments and artefacts. There was also a global movement to protect by law and provide resources and funds for monuments that were nationally important, but also those deemed significant to human civilization as a whole. Founded in 1945, has many responsibilities, one of the most important as far as archaeological conservation is concerned is the World Heritage List. The list began in 1975 as a recognition of globally important sites. The first 12 added on that first day included: L’Anse Aux Meadows in Canada, The Galapagos Islands, Quito in Ecuador, Krakow, and Mesa Verde National Park in the US. Today, there are over 1,000 cultural monuments and natural landscapes on this list. In the 21st century, it is common for countries to have laws in place to protect monuments, sites, and landscapes of cultural or historical importance and governmentestablished charities or government departments assigned to their management, upkeep or conservation. The threats to them and their conservation go beyond the issues of the 19th century (plunder and theft)
