It’s probably the most painstaking, heart wrenching, and stress inducing test of dedication a marriage can face. But the reward at the end is pretty sweet. At the annual Wife Carrying World Championships in Sonkajärvi, Finland, male competitors race around a track hauling their female partners on their backs. Winner takes home his wife’s weight in beer. It’s no ordinary racetrack, either. Competitors must wade through a neck-deep pool of water, climb over hurdles, and run through pits of sand before crossing the finish line. While some participants don crazy costumes for the pre-race, the actual event is pretty straightlaced. Wives must weigh at least 49 kilograms (108 pounds). Any woman lighter than that is required to carry a heavy rucksack until she reaches this minimum. A participant who drops his wife will be penalized 15 seconds. But there is one catch: contestants don’t have to carry their own wives. A friend’s wife, stranger’s wife, or even a random grandmother will do – as long as she’s over 17. Contestants flock from 47 countries across the globe to show their stuff in this epic display of brute strength. This year, Finnish couple Taisto Miettinen and Kristiina Haapanen captured the title for the fourth consecutive year. The 46-year-old lawyer and his wife completed the 235-meter course in one minute and four seconds. Like any dedicated athlete, Miettinen reported that he’d been training for a while. “In last autumn, I started running in the track, one hundred, two hundred and four hundred meters,” Miettinen said in a post-race interview. He also practiced the course in ski boots to build leg strength. The competition, which began in 1992, is supposedly rooted in the legend of Ronkainen the Robber — a hardnosed gang leader who hazed potential members by making them lug sacks of grain or live pigs over a similar course. He and his comrades also made a habit of stealing women from neighboring villages as a nod to this practice, many men “steal” friends’ wives for the competition. If you want to compete but can’t make it to Finland, there’s a North American version of the contest held in October at Sunday River Resort in Maine. With 100-plus pounds of brewski on the line, you might want to tell your significant other to start shaping up.
4. According to paragraph 2, Which of the following is NOT mentioned as a task for competitors to cross on the racetrack?

Read the following passage and choose the best answer (A, B, C, D):
My children can’t live without media. At age 14, 15 and 18, my daughters Sussy and Anni and my son Bill don’t use media. They inhabit media. And they do so exactly as fish inhabit a pond. Gracefully, and without consciousness and curiosity as to how they got there. They don’t remember a time before email or instant messaging or Google. When my children laugh, they don’t say “Ha, ha”. They say “LOL”. These are children who shrug indifferently when they lose their iPods, with all 5000 tunes plus video clips, feature films, and TV shows (like who watches TV on a television anymore?). “There is plenty more where that came from”, their attitude says. And they seem right. The digital content that powers their world can never truly be destroyed. As a social scientist, journalist, and mother, I’ve always been an enthusiastic user of information technology. But I’d noticed that the more we seemed to communicate as individuals, the less we seemed to function together as a family. And on a broader scale, that the more facts we have at our fingertips, the less we seem to know. That the “convenience” of messaging media (email, SMS, IM) consumes ever larger amounts of our time. That as a culture we are practically swimming in entertainment, yet remain more depressed than any people who have ever lived. Our family’s self-imposed exile from the information age changed our lives infinitely for the better. I watched as my children became more focused. I watched as their attention spans increased, allowing them to read for hours at a time; to hold longer and more complex conversations with adults and among themselves. They probably did no more homework during The Experiment than they had done before, but they all completed it far more efficiently and far more quickly The Experiment also forced us to notice food more. Before, eating had been a side dish. Now it was the main course, or at least one of them. Our approach to cooking changed, too, especially for the girls. They’d started out as reasonably competent cooks, but by the end of The Experiment they were capable of turning out entire meals with ease The Experiment also confirmed my strong suspicion that media has been robbing Sussy of sleep for years. Unplugged, the changes to her sleep patterns were dramatic. The evidence strongly suggests she is no isolated case. One study found that children who spend more time online also drink more caffeinated beverages, with a resulting effect on their prospects of sleeping well

Read the following passage and choose the best answer (A, B, C, D):
It’s extremely important for kids of middle childhood to continue, or to start to lead a healthy lifestyle, including eating nutritious meals as well as getting plenty of exercise and adequate sleep every day. These positive health habits will help children grow strong, stay healthy, and decrease the likelihood that they will become obese. Childhood obesity rates have increasing dramatically in recent years. According to the Centers for Disease Control, in 2004, 18.8% of school-aged children were obese, versus 4% of children 30 years before in 1974. Children’s skyrocketing rate of obesity is worrisome because it greatly increases children’s risk for remaining obese in adulthood, which in turn raises their risk for heart disease, stroke, cancer, diabetes, and premature death as adults. Obese children may also develop associated health problems during the middle childhood stage, such as high blood pressure, high cholesterol levels, and respiratory problems. Obesity can also set the stage for problems with self esteem, depression, anxiety and social ostracism, and/or being victimized by bullies Healthy diet and adequate exercise are important in preventing Type II diabetes in childhood as well as obesity. Diabetes is a metabolic disease in which the body cannot properly metabolize the sugars from food. Because the body cannot metabolize sugars, the sugars accumulate in the bloodstream instead and ultimately stress children’s kidneys, heart, circulatory system, and eyes. Insulin, which is created in the pancreas, is the chemical that breaks down blood sugar. In Type II diabetes, the body does not produce enough insulin to deal with all the sugars coming into the body. This medical diagnosis used to be called “adult-onset diabetes” because the disorder primarily affected adults with poor eating and activity habits. Today, however, this illness is now diagnosed in America’s children far more than in adults. It is now referred to as “Type II diabetes”, to reflect this shift in prevalence. In contrast to the many youth in America who overeat and don’t get enough exercise, other children become obsessed with over-controlling their food intake and with exercising too much. With the constant barrage of perfect, photoshopped bodies in the media today, many children are feeling pressure at younger and younger ages to imitate those images. Children as young as 6 are reporting that they are trying to lose weight by dieting. Overemphasis on extreme thinness can put children at risk for poor self-esteem, unhealthy exercise patterns, and eating disorders such as anorexia and bulimia. Children who embrace healthy eating and exercise habits during middle childhood will have a much easier time maintaining a healthy lifestyle through adolescence and adulthood than individuals who try to make the shift later in life. Teaching children to habitually eat moderate portion sizes and to choose healthy foods in preference to junk foods becomes increasingly important as children begin to spend more time away from home and gain more independence over their food and activity choices. Even though parents have less control over their children’s eating habits during middle childhood than when children were younger, it remains vital that parents continue to reinforce children’s healthy habits whenever possible. 
4. According to paragraph 3, Type II diabetes starts when _____

People have been donating blood since the early twentieth century to help accident victims and patients undergoing surgical (1)_____. Usually a pint of whole blood is donated, and it is then divided into platelets, white blood cells, and red blood cells. People can donate blood (for red blood cells) about once every two months.

The blood flows through a plastic tube to a collection bag or bottle (4)_______ contains sodium citrate, which prevents the blood from clotting. When the blood is given to a patient, a plastic tube and hypodermic needle are connected to the recipient’s arm. The blood flows down from the container by gravity. This is a slow process and may last as long as 2 hours to complete the infusion of blood into the recipient. The patient is protected (5)______ being infected during the transfusion. Only sterile containers, tubing, and needles are used, and this helps ensure that transfused or stored blood is not exposed to disease causing bacteria

Read the following passage and choose the best answer (A, B, C, D):
Traditional media come from the people and antecede the mass media; their appeal has historically been both functional and aesthetic. Whether of roughly hewn folk origins or of classifically rigid moulds, they have always served to entertain, educate to reinforce existing ideas or ideologies or to change existing values and attitudes. In other words, it is a means of changing values, attitudes and norms in order to provide a proper climate for social and economic progress. It is also a method of promoting certain behavioural acts or patterns. The aim is to get people to perform specific acts to achieve objectives of national policy (e.g. visiting clinics, investing in bonds, using fertilizer). Moreover, it is a channel for conveying information about available techniques and facilities which people may use to solve problems. Being close to people at the local level, these channels are potentially useful in the service of social concerns, as determined by local, provincial or national authorities themselves. They are, moreover, abundantly present in areas where mass media technology has not been fully or effectively developed to capture sustained interest at local, provincial or national levels. Folk media are personal forms of entertainment and communication. This is important because behavioural changes are most easily brought about by personal interaction. These forms of art are a part of the way of life of a community and provide acceptable means of bringing development issues into the community in its own-terms. They are capable of reaching intimate social groups, thus making use of already established communication networks in the audience. 
3. What is the easiest way to change a person’s behaviour?

Read the following passage and choose the best answer (A, B, C, D):
The comings and goings of teenagers, while a frequent source of tension in the  parent–child relationship, are a crucial experience in the construction of social identities. For this age group, mobility is not just a practice that is socially determined – by social background, residential environment and schooling – but also a specific experience that durably shapes their relationships with the spaces and the social world they encounter.  Although mobility is a socialised practice, based on habits forged in the domestic, residential and school environments, it is itself a specific experience in teenage socialisation. At this age, mobility plays an important role in individuals’ learning of behaviours and ways of being, gradually reshaping the dispositions acquired during primary socialisation.  First of all, mobility affects teenagers’ ways of being and behaving within their peer group, which play an increasingly important role in teenage socialisation. At this age, peers become more and more involved in mobility practices: they are one of the key reasons for mobility but, above all, they become preferred partners in self-mobility situations.  Furthermore, the movements of teenagers, alone or in groups, gradually reshapes their dispositions vis-à-vis mobility, particularly those acquired in the domestic sphere. At this age, experiences in mobility have lasting effects on the future practices of teenagers. They sometimes help modify the dispositions of teenagers regarding transport modes. We could cite, among other examples, the case of a girl whose fear of the metro gradually diminished as a result of occasional trips with her best friend, who was more familiar with this mode of transport. These experiences also influence the spatial amplitude of future mobility, in particular preferences for travel within or outside one’s area of residence.  Lastly, mobility allows teenagers to discover the public domain, when it gives rise to interactions that take place under the gaze of an incidental audience and which are therefore subject to specific rules. In the course of their travels, teenagers gradually become familiar with these rules, and they mutually adapt their behaviours to those of other citizens so as to eventually find their place within the public domain. Listening to music on mobile phones on public transport, for example, is appropriate to a greater or lesser extent, depending on the circumstances at the time.
3. According to paragraph 3, in what way can peers become one of the main reasons for mobility?

Read the passage below and choose one correct answer for each question.

Movements and gestures by the hands, arms, legs, and other parts of the body and face are the most pervasive types of nonverbal messages and the most difficult to control. It is estimated that there are over 200.000 physical signs capable of stimulating meaning in another person. For example, there are 23 distinct eyebrow movements, each capable of stimulating a different meaning. Humans express attitudes toward themselves and vividly through body movements and postures. Body movements express true messages about feelings that cannot be masked. Because such avenues of communication are visual, they travel much farther than spoken words and are unaffected by the presence of noise that interrupt, or cancels out speech. People communicate by the way they walk, stand, and sit. We tend to be more relaxed with friends or when addressing those of lower status. Body orientation also indicates status or liking of the other individual. More direct orientation is related to a more positive attitude. Body movements and postures alone have no exact meaning, but they can greatly support or reject the spoken word. If these two means of communication are dichotomized and contradict each other, some result will be a disordered image and most often the nonverbal will dominate.

Face gestures ________.

Music can bring us to tears or to our feet, drive us into battle or lull us to sleep. Music is indeed remarkable in its power over all humankind, and perhaps for that very reason, no human culture on earth has ever lived without it. From discoveries made in France and Slovenia, even Neanderthal man, as long as 53,000 years ago, had developed surprisingly sophisticated, sweet- sounding flutes carved from animal bones. It is perhaps then, no accident that music should strike such a chord with the limbic system – an ancient part of our brain, evolutionarily speaking, and one that we share with much of the animal kingdom. Some researchers even propose that music came into this world long before the human race ever did. For example, the fact that whale and human music have so much in common even though our evolutionary paths have not intersected for nearly 60 million years suggests that music may predate humans. They assert that rather than being the inventors of music, we are latecomers to the musical scene.
Humpback whale composers employ many of the same tricks that human songwriters do. In addition to using similar rhythms, humpbacks keep musical phrases to a few seconds, creating themes out of several phrases before singing the next one. Whale songs in general are no longer than symphony movements, perhaps because they have a similar attention span. Even though they can sing over a range of seven octaves, the whales typically sing in key, spreading adjacent notes no farther apart than a scale. They mix percussive and pure tones in pretty much the same ratios as human composers – and follow their ABA form, in which a theme is presented, elaborated on and then revisited in a slightly modified form. Perhaps most amazing, humpback whale songs include repeating refrains that rhyme. It has been suggested that whales might use rhymes for exactly the same reasons that we do: as devices to help them remember. Whale songs can also be

rather catchy. When a few humpbacks from the Indian Ocean strayed into the Pacific, some of the whales they met there quickly changed their tunes – singing the new whales’ songs within three short years. Some scientists are even tempted to speculate that a universal music awaits discovery.

Read the following passage and choose the best answer (A, B, C, D):
The biggest difference between an eco-lodge and a green hotel is the setting in which you’ll find them. Eco lodges tend to be more remote, located in relatively pristine natural environments such as beaches, jungles and mountains. Green hotels, on the other hand, are more often associated with cities and towns. Eco lodges and green hotels both emphasize elements such as environmental responsibility and minimizing negative impact. The best ones offer renewable energy sources, recycling services, eco-friendly toiletries, energy efficient lighting, locally sourced food, organic linens and towels, non-toxic cleaning supplies, non-disposable dishes, water conservation methods and various other sustainability-focused initiatives. But eco lodges tend to be more dependent on the natural environment than green hotels. They are also generally more active in nature and wildlife conservation, more focused on educating visitors about the flora and fauna of local ecosystems, and more deeply connected with the area’s indigenous culture (whose influence is often incorporated into the lodge’s decor and restaurant menu). The best eco lodges also work to ensure positive relationships with the local people. They train and employ them at fair wages, take part in community development initiatives, offer activities that help visitors conserve and appreciate local customs, and contribute to the local economy. In this way, they reinforce the notion of ecotourism as a more sustainable long-term business model than altering or destroying habitats for quick financial gains

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.

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. 
5. According to paragraph 4, why should prolonged conflict be avoided?

Read the following passage and choose the best answer (A, B, C, D):
The walnut tree produces wood that is used for countless purposes, and is considered the finest wood in the world. The wood is easy to work with, yet it is very hard and durable - and when it is polished, it produces a rich, dark luster. It also shrinks and swells less than any other wood, which makes it especially desirable for fine furniture, flooring, and even gun stocks. In fact, just about every part of the walnut is unusually hard and strong. The nut of the tree is encased inside a very hard shell, which itself is enclosed in a leathery outer covering called a husk. It requires real effort to break through those layers to get at the tasty meat inside. Yet every part of the walnut is useful to people. The outer husk produces a dark reddish stain that is hard to remove from the hands of the person who opens the nut, and this pigment is widely used in dyes and wood stains. The inner shell is used as an abrasive to clean jet engines. And the meat of the nut is extensively used in cooking, ice cream, flavourings - and just eaten raw. Walnut trees exude a chemical into the soil near their roots which can be poisonous to some trees and shrubs. Fruit trees, for example, will not survive if planted too close to a walnut. Many other plants, such as maple trees or ivy, are not affected by the walnut’s presence, and are well-suited to grow in its vicinity

Read the following passage and choose the best answer (A, B, C, D):
Despite the fact that humans haven’t returned to the Moon since the cancellation of the Apollo program in 1972, there have nonetheless been incredible advances in space exploration in recent years. All across the world, human time is the most valuable commodity – particularly when it comes to solving problems. Far from stealing jobs, the majority of advances in artificial intelligence and machine learning are designed to automate relatively “simple” processes and free up time for humans to do what they do best. Already we have had a taste of what AI can achieve from space, even as far back as the early 2000s with the launch of the Earth Observing-1 (EO-1) satellite, which helps analyse and inform the appropriate response in the event of a disaster, such as hurricanes and volcanic eruptions. In some cases, the systems in place on EO-1 began capturing satellite images of disaster zones before ground personnel were even aware that a disaster had occurred. More recently, AI has been used on the Mars Curiosity rover, where AEGIS software is able to identify intriguing rock or soil patches that should be targeted for analysis. This significantly expedites the process of collecting data from the surface of Mars as the robot isn’t relying solely on human commands. Richard Branson’s Virgin Galactic – which hopes to soon begin conducting commercial flights – charges between $200,000 to $250,000 per ticket for a flight where passengers will experience just several minutes of weightlessness beyond the Karman line where space officially begins. Therefore, previous space missions have always needed to consider very carefully which astronauts they send to space, with the ultimate decision often coming down to an astronaut’s ability to act as a ‘jack-of-all-trade’. In future, it should be possible to automate the computing and engineering tasks that historically astronauts have had to train for. This would mean sending individuals with specialised expertise in science and research in place of the all-rounder astronauts of yesteryear. For success in space exploration in the years to come, we will need to continue along the exponential curve of open source uptake and see advances in the approach to how spacecraft software, hardware and infrastructure is developed and deployed. With this baseline in place, advances in AI-driven scientific research have the potential to propel us forwards.

Read the following passage and choose the best answer (A, B, C, D):
Human’s avarice for ivory has resulted in thousands of unfathomable elephant atrocities and senseless suffering that has pushed the species to the brink of extinction. In 2015, the U.S. and China announced they will work together to enact a near complete ban on the import and export of ivory. As an industry that has largely been driven by China and, if substantiated, these claims could be a ray of light for one of the most endangered animals in the kingdom. However, as the famous saying goes, “for every action, there is an equal and opposite reaction.” With the worldwide attention on elephant ivory, hippo teeth, which can grow up to three-feet-long, have become the next target. Since the United Nations Convention on International Trade in Endangered Species officially imposed a ban on ivory trading in 1990, about 30,000 pounds per year of hippo teeth have been exported from Africa. On a recent trip to Kenya, I had the unfortunate displeasure of meeting these facts face-to-face. On the banks of the Mara River, the infamous transient point of the great wildebeest migration, I met a Conservancy Ranger, a local Kenyan, named Ivan. He led me along a narrow path above the riverbed to view pods of hippos. They clumped together in the river, every few minutes lifting their heads above the waterline to welcome my arrival. Despite their label as one of the most dangerous animals in Africa, they were playful to watch. Their tiny ears and eyes would appear from the murky river and then, with a splash, they would disappear. The river is everything to the hippo, Ivan explained, it is their lifeline. The only real time they leave the river is during their nightly ritual of traveling to nearby plains to consume grasses. Contrary to their aggressiveness, they are vegetarians. As we neared the end of our trek, we reached the Mara Bridge, spanning the divide between Kenya and Tanzania. An undeniable stench filled the air. Our gaze fell to the water beneath the structure, and as if to mark the metaphorical significance of the passage, lay a poached hippo. It had been killed the previous night, probably as it grazed unsuspectingly under the cover of darkness. They had found spear punctures in its body, and its teeth were missing. It had somehow, in unthinkable pain, made its way back to the river, its home, to die.
5. According to the third paragraph, which of the following information is NOT true about hippos?

Of the six outer planets, Mars, commonly called the red planet, is the closest to Earth. Mars, 4,200 miles in diameter and 55 percent of the size of Earth, is 34,600,000 miles from Earth, and 141,000,000 miles from the Sun. It takes this planet, along with its two moons, Phobos and Deimos, 1.88 years to circle the Sun, compared to 365 days for the Earth.

For many years, Mars had been thought of as the planet with the man-made canals, supposedly discovered by an Italian astronomer, Schiaparelli, in 1877. With the United States spacecraft Viking I's landing on Mars in 1976, the man-made canal theory was proven to be only a myth.

Viking I, after landing on the soil of Mars, performed many scientific experiments and took numerous pictures. The pictures showed that the red color of the planet is due to the reddish, rocky Martian soil. No biological life was found, though it had been speculated by many scientists. The Viking also monitored many weather changes including violent dust storms. Some water vapor, polar ice, and permafrost (frost below the surface) were found, indicating that at one time there were significant quantities of water on this distant planet. Evidence collected by the spacecraft shows some present volcanic action, though the volcanoes are believed to be dormant, if not extinct.

The Viking I exploration accomplished all of the following EXCEPT___________ ______ .

Four West Indian geckos, with human assistance, have recently entered the United States. The yellowheaded gecko, the ashy gecko, the reef gecko, and the ocellated gecko are presently inhabiting the tropical areas of the Keys and the tip of southern Florida. The Mediterranean gecko also arrived along the Gulf coast some time ago, via the West Indies. The only other geckos in the United States live in the Southwest. In extreme southern California, the leaf-gingered gecko lives

in dry, rocky country and scampers over boulders at night, hiding by day in crevices. It has a slender, tapered tail and stalks insects by raising itself high on its legs, cocking its head, and twitching its tail nervously before leaping on its prey. In courtship, the tail is also waved by the male as he approaches the female.
Although most lizards are excellent climbers, the geckos are able to walk on smooth surfaces with the help of unique clinging devices under the toes. Also, the undersides of most geckos have pads of large scales, each of which bear microscopic hairs with hundreds of branches having minute, blunt ends that press against the surface that the gecko is on, enabling the gecko to cling to almost any surface. Like other lizards, geckos have the ability to shed their tails if attacked by an enemy. They stump heels and a new tail is grown in approximately the same shape as the original. Unlike most lizards, most geckos have no moveable eyelids. The nocturnal geckos have vertical pupils, which contract in bright light. All geckos, except several New Zealand species, lay eggs. The eggs have a tough, white shell and are laid under stones, behind window shutters or under bark.

According to the passage, the banded gecko .
