mmlu_train_48862 | Scientist Florence Wambugu works with farmers in Kenya, a country in East Africa. She helps them grow bigger and better crops. Wambugu is especially interested in finding simple ways to produce more food. In the past ten years, Wambugu has spent much of her time studying sweet potatoes, which are an important food in her part of Kenya. A virus kept attacking the plants. It stopped the sweet potatoes from growing well. Because of the virus, some farmers lost three quarters of their crops. Wambugu went to war against the virus. Her research for a way to save the sweet potatoes led to a lab in St. Louis, Missouri. The lab mainly works on genes , the chemical "computer programs" found in the cells of living things. Genes tell a plant to produce pink flowers or an animal to grow black hair. Now scientists have found ways to move genes from one living thing to another. That process is called genetic engineering. Wambugu spent three years in the lab. As a result, she created a sweet potato plant that could fight off the virus. Wambugu tested her research in Kenya, and her plants produced wonderful sweet potatoes. That's just the beginning, Wambugu believes. Genetically modified foods, she thinks, could help farmers in poor countries grow badly needed crops, thus, fewer people will go hungry. What caused Wambugu to set up a lab in St. Louis, Missouri? | [

mmlu_train_37711 | We have seen that humor and laughter positively influence our body in many ways, but little research has been done on whether a better sense of humor actually helps keep you from getting sick. However, since people with a better sense of humor have higher IgA levels, and since research has shown that those with higher levels of salivary IgA are less likely to get colds or be infected with Streptococcus, humor should reduce the frequency of colds. The only study to directly examine this question found that the impact of one's sense of humor upon colds depends on the kind of sense of humor you have. It was only individuals whose sense of humor took the form of seeking out and appreciating humor who had fewer and less severe colds/flu than their low humor counterparts. Surprisingly, those whose sense of humor took the form of initiating humor more often did not have fewer or less severe colds/flu. The researchers argued that being a person who likes to tell jokes or otherwise initiate humor takes them into more frequent contact with other people, which serves to expose them to infectious agents more often, robbing them of the advantage that a more active sense of humor otherwise offers. Obviously, more research is required to clear up this confusing picture. The importance of active use of one's sense of humor in producing humor's health benefits was confirmed in another study in an unusual way. It found that among a group of mothers with newborn infants, those who actively used humor to cope with the stress in their lives had fewer upper respiratory infections and their infants also had fewer infections. This seemed to be because these mothers had higher levels of immunoglobulin A (A) in their breast milk. Among adults, if we look at bodily symptoms alone, independent of any diagnosed illness, there is some evidence that individuals who have more negative reactions to humor report more bodily symptoms and complaints. Students complaining of cardiovascular symptoms and gastroenterological symptoms also have been shown to have this more negative reaction to humor. According to the passage, IgA is _ . | [

mmlu_train_42916 | A campaign is being launched to encourage children to _ 30 minutes of screen time a day to head for the great outdoors. The newly formed Wild Network--a collaboration of nearly 400 organizations--is attempting to attract youngsters away from television and computer screen and to fields, woods and parks. Members of the network include the National Trust, RSPB, Play England and the NHS. Organizers say it is the UK's biggest ever campaign to reconnect children with nature and outdoor play, and claim it could help improve fitness, mental alertness and general wellbeing. A documentary film, Project Wild Thing, will forecast the launch at more than 50 cinemas across the UK from Friday. It looks at the increasing link between children and nature. Andy Simpson, chairman of the Wild Network, said, "The tragic truth is that kids have lost touch with nature and the outdoors in just one generation. Time spent outdoors is down, roaming ranges have fallen largely, activity levels are declining and the ability to identify common species has been lost." Suggestions of how to get more time in nature include collecting conkers , camping or snail racing, and observing autumn colour on trees. From January, the network will aim to make suggestions to politicians on how government can do more to get children muddy and bright-eyed. This is not the first time the message of less screen, more play has been brought up. Children in the 1980s were requested to do the same by the BBC TV series Why Don't You, which somewhat confusingly called on its viewers to "switch off your TV set and go to do something less boring instead". Which of the following shows that kids have lost touch with nature and the outdoors? | [

mmlu_train_25462 | It's impolite to spit out the first bite of your dinner. But to a type of Australian snake, this rude behavior is a matter of life and death. The snake, called a floodplain death adder , eats two types of frogs that are hard to stomach. The frogs produce chemicals to defend them from predators . One of these species, the Dahl's frog, can kill a snake that tries to eat it. The other species, the marbled frog, is less dangerous but still tough to eat. When attacked, _ produces a glue like substance. Leaves and branches get caught up in this material, making a big sticky mess that gets in the way of anything trying to swallow it. A marbled frog can even get stuck on the head of an attacking snake. Both frogs have good defense methods. But the floodplain death adder knows how to get around each of them. Floodplain death adders quickly strike these frogs, using their poisonous teeth to inject poison. But then, instead of swallowing their dinner immediately, the snakes sit back and wait for their preys to become safe to eat. That's because both the Dahl's frog's protective toxin and the marbled frog's glue break down over time. After a while, the frog toxin is no longer poisonous and the glue is no longer sticky. The two substances break down at different rates, and floodplain death adders seem to know the difference, And adder waits for a different length of time depending on the species of frog it just struck. The stickiness of the marbled frog glue decreased by as much as two-thirds after just 10 minutes. And that's just about how long an adder waits before eating a marbled frog. On the other hand, the snakes wait for about 40 minutes before eating a Dahl's frog. That's enough time for the frog's toxin to break down into harmless substances. But even a quick strike gives a taste of the Dahl frog's toxin. After striking such a frog, a floodplain death adder thrashes around and lies on its back with its mouth open, It's like the snake has just had a mouthful of chili pepper. By comparison, when given frogs that have no chemical defenses, floodplain death adders eat their prey immediately after striking. Snakes, despite the fact that they've got this tiny pea-size brain are clearly capable of recognizing what kind of frog they've bitten. The glue produced by the marbled frog is used for_. | [

mmlu_train_73844 | Have you ever wondered how and why a fall leaf changes color? We first have to understand what leaves are and what they do. Plants are the world's food factories. Plants take water from the ground and take CO2from the air. Plants use sunlight to turn water and CO2into glucose . Glucose is a kind of sugar. Using it as food, plants get energy and grow. Plants using sunlight to turn water and CO2into sugar is called photosynthesis . _ helps photosynthesis. It gives plants their green color. As summer ends and autumn comes, the days get shorter and shorter, and trees "know" to begin getting ready for winter. During winter, there is not enough light or water for photosynthesis. Trees rest during this time and live on the food they store during the summer. They begin to shut down their food -- making factories. As the green chlorophyII disappears from the leaves, we begin to see yellow and orange leaves. These colors have been in the leaves all the time. We just can't see them in the summer, because they are covered up by the green chlorophyII. The bright reds and purples we see in leaves are made mostly in autumn. In some trees, glucose is caught in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn turn this glucose into a red color. The brown color of trees is made from waste left in the leaves. It is mixture of all these things. It makes the beautiful leaves during autumn. . Plants use sunlight to turn _ into sugar. | [

mmlu_train_73872 | What Is Self-tracking All about Perhaps you've tracked how many kilometers you've run, how many hours you've slept or how much you've eaten in a day. If so, you've taken part in a popular movement called the "Quantified Self Movement" or "Self-tracking". Maybe you've wanted to change a bad habit but couldn't. Self-tracking may be your answer. The idea is to collect information about your everyday activities and analyze them to help improve and form a healthier lifestyle. Recently, tools such as smartphones, apps, along with newly published wearable things, are making self-tracking easy. Today, one can use Fitbit, the Jawbone Up, Google Glass or a smart watch to record personal data including sleeping hours, stress levels, heart rate and mood. So why does a person self-track? Someone may be trying to lose weight or improve their sleep. Another person feels tired after eating. Self-tracking could help him to know what foods make him sleepy and watch his diet. [:Z#xx#k.Com] Tracking daily activities isn't a new concept. In years past, athletes and their coaches kept notes food, training and sleep in order to achieve an athletic goal. Similarly, doctors have also helped patients to record parts of their lifestyles and eating habits to help fight health problems. However, it wasn't until 2007 that magazine writers Gary Wolf and Kim Kelly created the term "Quantified Self" or "self-tracking". Although self-tracking has many advantages, Dennis Nash, president of Data Speaks Health Solutions, says self-tracking has its disadvantages. Once people start tracking their daily activities, it can become an extra task people like to do often. Also, they might begin to worry too much about their health. Though self-tracking doesn't make sure that one's quality of life will improve, it can encourage people to make healthier choices. You can find this article in the part of _ . | [

mmlu_train_35079 | Scientists have always been interested in the high level of organization in ant societies. American researchers have watched ants build life-saving rafts to keep afloat during floods. They also have documented how ant colonies choose their next queen--the female whose job is to produce eggs rather than seek food for others. New technology is helping to improve researchers' understanding of the insects. But there is still a lot to be learned. Fire ants living in Brazilian forests are perfectly at home in an environment where flooding is common. To save themselves, the insects connect their legs together and create floating rafts. Some ant rafts can be up to 20 centimeters wide. David Hu who is a mechanical engineer with the Georgia Institute of Technology, also known as Georgia Tech, says, "If you have 100 ants, which means 600 legs, 99 percent of those legs will be connected to a neighbor. So they're very, very good at maintaining this network." David Hu and other Georgia Tech researchers want to study ants and the secret of their engineering. They freeze ant rafts and then look at them with the help of computed technology, or CT, images. The pictures show that larger ants serve in central positions to which smaller ants hold. The larger ants form pockets of air that keep the insects afloat. Scientists say small robots or materials that can change shape could be programmed in a similar way, working towards a shared goal. Researchers at North Carolina State University are also studying ants. They examined how Indian jumping ants choose the leader of the colony when they lose their top female or queen.

mmlu_train_58201 | An African-born British scientist received an environment research prize for showing how bees can be used to reduce conflict between people and elephants. Lucy King's work proved that beehive "fences" can keep elephants out of African farmers' fields. The animals are scared of bees, which can bite them inside their long noses, and flee when they hear buzzing . Dr King's work offers an intelligent solution to an age-old challenge, while providing further confirmation of the importance of bees to people and a really clever way of preserving the world's largest land animal for current and future generations. Working in Kenya, Dr King and her team showed that more than 90% of elephants will flee when they hear the sounds of buzzing bees. Afterwards, they also found that elephants produce a special sound to warn their fellows of the danger. They used the findings to construct barriers where beehives are woven into a fence, keeping the elephants away from places where people live and grow food. A two-year project involving 34 farms showed that elephants trying to go through the fences would shake them, disturbing the bees. Later, the fences were adopted by farming communities in three Kenyan districts , who also made increased amounts of money from selling honey. As Africa's population grows, competition for space between people and elephants is becoming more serious, and there are _ on both sides. The same is true in parts of Asia. Sri Lanka alone sees the deaths of an estimated 60 people and 200 elephants each year from conflict. Lucy King now wants to see whether the Kenyan technique will work in other parts of Africa and perhaps, eventually, in Asia. Dr King's solution is described as "intelligent" because _ . | [

mmlu_train_26837 | Is carrying a few extra pounds into your senior years healthy? Advice has been mixed. Now, two studies published this month attempt to better define the ideal weight for fitness and longevity for adults over age 60. The main point is that you don't need to worry about being slightly overweight, as long as that extra weight is maintained at a consistent level. However, being very overweight is detrimental to health, and exercising to lose body fat and to gain muscle mass is always beneficial. Determining the ideal weight for older people has been a pursuit, with researchers looking for what weight is not too thin, but not too fat. Studies have suggested that being slightly overweight can be protective. For example, a 2001 study by researchers at Yale University found that moderately overweight senior adults with a body mass index (BMI) of 27 -- two points higher than the BMI of 25 that defines being overweight -- lived longer than seniors who were either thinner or heavier. There's a fine line here, though, because carrying extra pounds is a risk factor for many types of cancer and other diseases. And, according to the researchers behind the two new studies, the general public has misinterpreted the Yale findings to mean that being very overweight is healthy. One new study, published this month in the American Journal of Epidemiology by researchers at The Ohio State University in Columbus, found that seniors who maintained a stable, slightly overweight status survived most probably over the 16 years surveyed. Those seniors who had a so-called healthy weight going into the study (a BMI between 18.5 and 25) and who gained weight, but stayed below BMI 25, had a slight possibility of surviving over the study period. People in the obese group, with a BMI higher than 35 and who continued to gain weight, faced the worst among all the groups in the study. But next-to-last were normal-weight people who lost weight, but this was likely because they became sick, the researchers said. The second study, appearing this month in the journal Obesity, was conducted by researchers at Wake Forest Baptist Medical Center in Winston-Salem, N.C., and supports intentional weight loss among senior adults. Whether weight loss is beneficial has been debated because of this concept that being overweight is protective. In short, the researchers found that physical activity and weight loss for overweight and obese adults resulted in lower cardiovascular disease risk and improved mobility. This finding supports previous studies demonstrating that exercise builds muscle and bone strength, improves balance and coordination, prevents falls and enables seniors to enjoy a more active lifestyle, they said. Hui Zheng of Ohio State, the lead author of first study, said that the negative effects of obesity on health are greatest for young people. What does the passage mainly tell us? | [

mmlu_train_30783 | Mr. Black was the manager of a hotel in Atlanta. One weekend all of the hotels were full because of a large business meeting being held in the city. On Sunday night, three men came into Mr. Black's hotel and asked for rooms. Mr. Black told them that there were no more rooms available. The men didn't know what to do because they had no place to stay in. Mr. Black wanted to help them. He remembered that there was an empty room at the far end of the first floor -- Room 112. It was a very small room, and had rarely been used as a guest room before. So, he asked the three men if they would mind sharing that small room. They replied that they would be very satisfied so long as there was a room for them to stay in for the night. Mr. Black then told them that the room would cost them $ 30 in total. On hearing this, each of the three men gave Mr. Black $ 10 before they left for their room. However, Mr. Black soon began to think that $ 30 was really too much for that small room. He called his assistant over and said, "Here is $ 5. Give it back to the three men in Room 112. Each of them paid me $10. That's too much." The assistant took the money. While he was on the way to that small room, he thought, "How can three men divide $ 5? I'll give each of them only $ 1 and keep the $ 2 left to myself. The men will be happy to get anything back, and I can also make some money that way. After all, Mr. Black will never know anything about it." So, the assistant returned only $1 to each of the three men. Each man had first paid $ 10. After the assistant returned $1 to him, each man had actually paid only $ 9.

mmlu_train_21160 | Short people, studies have shown , are more likely to have a stroke , suffer from high blood pressures and heart disease and be bullied in school . Now, researchers report that short people--at least in the past--were also more likely to die at a younger age than their taller peers. Their study, published in the Journal of Epidemiology and Community Health , found that short bones have something to do with short life for more than 1,000 years. The conclusion was based on 490 sets of adult skeletal remains from an archaeological site in northeastern England , YC dating from the 9th century to about 1850 . About 55% of men and 73% of women died before the age of 45, and 39% of men and 56% of women died before age 30. The risk of death before age 30 declined as bone length increased. "This study provides evidence from an archaeological sample that long bone length is connected with age at death--those with smaller bones tend to die younger," according to Dr. D.J. Gunnell of the university of Bristol in the UK and colleagues . While it is not clear why short stature might be linked to earlier death , the researchers point out that height is _ of childhood nutrition, which may have long-lasting effect on health . "Mechanism for height-mortality associations in the past may differ from those today , for example , short stature may have increased the risk of death in childbirth and this may explain the higher risk of premature mortality in women," Gunnell and colleagues write . "However, short bones, it would appear, have always been a marker of a short life," the authors conclude. Short stature may be caused by _ . | [

mmlu_train_34460 | The Cuban iguana is a species of lizard of the iguana family. It is the largest of the West Indian rock iguanas, one of the most endangered groups of lizards. This species with red eyes and a thick tail is one of the largest lizards in the Caribbean. The Cuban iguana is primarily _ ; 95% of its diet consists of the leaves, flowers and fruits from as many as 30 plant species, including the seaside rock bush and various grasses. However, Cuban iguanas occasionally consume animal matter, and individuals have been observed eating the dead flesh of birds, fish and crabs, The researchers wrote that quite a few people on Isla Magueyes could have caused this incident. The Cuban iguana is distributed throughout the rocky southern coastal areas of mainland Cuba and its surrounding islands with a wild population booming on Isla Magueyes, Puerto Rico. It is also found on the Cayman Islands of Little Cayman and Cayman Brac, where a separate subspecies occurs. Females guard their nest sites and often nest in sites half destroyed by Cuban crocodiles. To avoid the attack from them, the Cuban iguana often makes its home within or near prickly-pear cacti . In general the species is in decline, more quickly on the mainland than on the outlying islands. One of the reasons for their decline is habitat destruction caused by the over consuming of farm animals, housing development, and the building of tourist resorts on the beaches where the animals prefer to build their nests. Although the wild population is in decline, the numbers of iguanas have been sharply increased as a result of captive-breeding and other conservation programs. .Why does the Cuban iguana build its nest near prickly-pear cacti? | [

mmlu_train_45219 | Finally, there is some good news for older dads. A new study shows that their children and even grandchildren may get a health benefit because of their older age. It's based on research into something called telomeres--tips on the ends of chromosomes Some previous studies have connected having longer telomeres with better health and longer lives. Telomeres haven't been proven to cause those benefits in the general population, but a number of researchers think they may hold secrets for things like longevity and cancer. As you age, telomeres shorten. However, previous studies have shown that the older a man is when he becomes a father, the longer the telomeres his children tend to have. The new research confirms that and finds it's extended to the grandchildren. That's a cheerier result for older dads than some other studies in recent years that indicate their kids are at higher risk for things like autism Carol Greider of Johns Hopkins University, who shared a Nobel Prize in 2009 for telomere research but didn't participate in the new study, said it's no surprise that the telomere effect would extend beyond children to grandchildren. She also said that since older fathers also tend to pass more potentially harmful genetic mutations , it's "not at all clear" whether advanced paternal age gives an overall health benefit to children. In a statement, the researchers who conducted the study said their study shouldn't be taken as a recommendation that men reproduce at older ages because there's a risk of genetic mutations. Some previous studies of the impact of older fatherhood have been less encouraging. In 2010, for example, at least two big studies confirmed a link to having children with autism. In 2008, a big Swedish study strengthened evidence linking bipolar disorder to older paternal ages. Which of the following statements about telomeres is NOT true? | [

mmlu_train_6436 | Besides the pain, what bothered Yang Zhihong the most during an operation were the female nurses in the operation room. "It couldn't be more embarrassing," said the 23-year-old senior student from Beijing Foreign Studies University, who underwent an operation at Peking University Third Hospital in March, for reasons of hygiene. "I just felt uneasy with women around me and my pants off, even if they're there to help with my operation." That wasn't the first time Yang thought there should be more male nurses in the hospital. "For a physical examination on private parts, it would be better to be helped by nurses of the same gender," he added. While their numbers have increased in recent years, male nurses still only account for less than 1% of all nurses in China, according to the Ministry of Health. In the United States and many European countries, the percentage of male nurses is around 10%, Beijing Peking University First Hospital head nurse Deng Jun said during a forum focusing on male nurses. "We need to come up with more male nurses to meet the deficiency for male nurses in China," he said. "The lack of male nurses is mainly due to the misconception that a nursing job is a disgraceful job requiring no technical skills with a comparatively poor salary," Deng said. "People hold the belief that men are too clumsy to clean a patient's body or take care of the sick. However, male nurses possess some unique features." In some high-pressure and fast-paced working environments, such as operating rooms or emergency rooms, male nurses definitely have an advantage as well, Deng said. "It's difficult for a female nurse to turn over a paralyzed patient by herself in an intensive care unit. And during natural disasters, earthquakes for example, male nurses also play a vital role in rescuing victims and providing healthcare in a dangerous environment." Men make up only 1,900 of the 69,000 registered nurses in the capital, and they mainly work in the departments that are "labor-demanding", according to the Beijing Municipal Health Bureau. "I've seen so many male nurses quit or resign in the past few years," he said. "With a basic salary of around 1,500 yuan, most male nurses simply find themselves cornered." "Many students even reject their identity as a male nurse, out of the long-existing discrimination," Zhao said. "But nursing truly needs the male because of their rational thinking, physical strength and calmness in face of emergency and disasters." Nothing will change "until the public changes its attitude and nurses' pay is raised", he said. A large number of men refuse to be a nurse partly because _ . | [

mmlu_train_51726 | For many men, the idea that they have a better sense of direction than women has been improved by a scientific study. Researchers from Norway scanned on the brains of volunteers as they completed navigation tasks to discover men are more skillful at finding their way because they use a separate part of their brain. According to lead researcher Dr. Cal Pintzka from the Norwegian University of Science and Technology (NTNU), men and women have different navigational strategies. Med use basic directions--the use of north, south, east and west--during navigation to a greater degree. Men's sense of direction was more effective. They quite simply got to their destination faster. "If they're going to the Students Society building in Trodheim, for example, men usually go into the general direction where it is located." Dr. Pintzka explained. Women usually orient themselves along a route to get there, for example, go past the hairdresser and then up the street and turn right after the shore. The study shows that using the basic directions is more efficient because it is a more flexible strategy. The destination can be reached faster because the strategy depends less on where you start. Meanwhile, the study also shows both men and women use large areas of the brain when they navigate, but some areas were different. The man used the hippocampus more, whereas women use their frontal areas to a greater extent. That degrees with the fact that the hippocampus is necessary to make use of basic directions. Losing one's sense of direction is one of the first symptoms in Alzheimer's disease. Understanding how men and women use different brain areas and strategies to navigate, researchers will be able to enhance the understand of the disease's development, and develop coping strategies for those already affected.

One study showed that forty percent of those killed in car accidents could have been saved if they have been wearing seat belts. Unfortunately seat belts are worn only by a small number of drivers and passengers _ about fifteen percent in cities and only nine percent in small towns. And safety belt can not protect people who do not wear them. In order to find out what kinds of people do wear seat belts, a study was made in several cities in of the United States. The following facts were learned about those who use their safety belts. 1. They do not smoke while driving. 2. They had more education than less educated people 3. They know some one who was hurt(but not killed) in an accident Advertisements based on these facts have been printed in newspapers and magazines in order to teach people the importance of using seat belt. But these advertisements have not helped much. Some people believe there should be a law ordering drivers and passengers to use safety belts.

Yet along my journalistic journey there have been several interviews that remain deeply in my memory. For not only did the characters of those specific people impress me, they actually influenced my life. Lynn R. Taylor is such a special person. Born in Buffalo, New York, on May 2, 1962, Lynn Taylor was just like all the other kids in her neighborhood. At the age of three she was diagnosed with Wilms Tumor, a cancer of the kidneys. Given a "no-chance" prediction, doctors completely removed one of Lynn's kidneys and part of another. They then predicted that if she survived to the age of five, she might possibly make ten. In the decade that followed, Lynn Taylor met and surpassed all medical experts' gloom-and-doom predictions. At the age of fourteen she was in full remission , and by seventeen, she was considered cured. Yet in this case, Lynn's medical history was far from closed. Over the next twenty-three years, Lynn earned her undergraduate degree and master's degree in economics. Then she was awarded a scholarship to study at the University of Sussex in England. There she was invited to teach and earned her second master's degree. Upon returning to Buffalo, the successful young woman engaged in a variety of high level jobs, including head of Multicultural Affairs at a local college. Recently Lynn has added a new activity to her schedule----that of a cancer hospital volunteer.

mmlu_train_13006 | What do you do if you don't get into your first choice of university? That's the dilemma that faces thousands of British students every year. Many candidates turn to Clearing, the service that helps find university places for students at the last moment. If they don't have the marks to get into their first choice of institution, Clearing tells them about places available at other universities, though they might have to read another subject. But this year has seen a record number of people applying to university. This, combined with the weak economy, an uncertain job market and budget cuts at universities, means that _ than usual. Some sources say six students have applied for each remaining undergraduate university place. The British university admissions service, UCAS, says up to a quarter of this year's university applicants --- almost 190,000 people --- still don't have a place on a degree course. That's a rise of over 46,000 students from last year. Faced with these figures, some British students might be thinking of an interesting alternative: studying abroad. The University of Nottingham, for example,is offering places at its campuses in Ningbo, near Shanghai, and Kuala Lumpur, Malaysia. Students here can gain University of Nottingham degrees in business, accounting, engineering and English. Similarly, the University of Bolton says it has 'unlimited' places at its campus in the United Arab Emirates. Given the problems getting into university, the UK's Higher Education Minister, David Willetts, encourages students who haven't made the grade to consider alternatives to university, such as apprenticeships and studying at home. "There are a range of options available," he says. "People are able to reapply. They should think how they can spend their year adding that bit to their CV, which would help their application --- getting practical work experience or extra skills --- anything that strengthens their chances next year." But some experts say that rising university costs, poor long-term job prospects, and a drop in graduate recruitment mean it's the worst time to be a university student in the UK. According to UCAS, there are about _ university applicants this year. | [

According to the list, "password" is the worst and most common password. Many others on the list are numbers in order either forward (for example,1234) or backward. Letters on the keyboard in order, such as "qwerty" are also common, as well as some first names and animals. "Hackers can easily break into many accounts just by trying common passwords again and again, " said Morgan Slain, CEO of Splash Data. How can you make a strong password? It should be eight characters or more, with a mix of letters, numbers and symbols. One way to create a long and easy-to-remember password is to separate short words with spaces or numbers. Having safe passwords is necessary for surfing the Internet safely. But it's not the only thing you must do to keep safety online. Here are some other web safety tips: *Never give out information that will allow someone to find you offline.

Indoor and outdoor rock climbing are both extremely demanding and require practice to get good at. It is one of the most physically and mentally demanding sports. There are three basic types of rock climbing. Top roping is the most common type and the climber need to climb with a partner. The second type, which is very similar to top roping, is called lead climbing. In both of the types, the climber can sit off the wall and rest on the rope. The third type is called bouldering. Bouldering is a type of free climbing without any ropes. This is the most demanding of all climbing types. The climber must be able to complete the climbing without taking a rest on the rope. Believe it or not, climbing is said to be about 75% legs and only 25% arms. To climb efficiently and successfully, a person needs to have a wonderful technique. One of the major rules of rock climbing is to always have three points touching the wall, whether it is both feet and one hand, or one foot and both hands, as it is much easier to have your weight cases will not do the climbing; they only hold you into the wall so that your legs are actually pushing you upward. Also, the closer you are to the wall, the easier it is to climb. Rock climbing may sound a bit too extreme for the everyday person, but it is really an amazing workout. Once you get into the sport, and learn how to position your body and rest your weight, then you can begin to deal with some difficult problems. The great thing about rock climbing is that it is mentally challenging as well. You are constantly analyzing the way your body moves and how to do certain moves on the wall. For anyone who wants to get into shape, rock climbing is a fun and effective way to exercise muscles. _ will make rock climbing easier. | [

mmlu_train_53428 | Neumann was the oldest of 3 children of a banker, and his speed of learning new ideas and of solving problems stood out early.At 17, his father tried to persuade him not to become a mathematician because he may lead a poor life being a mathematician, and so Neumann agreed to study chemistry as well.In 1926, at 23, he received a degree in chemical engineering and a Ph.D.in mathematics.From then on, mathematic provided well enough for him, and he never had to turn to chemistry. In 1930, Neumann visited Princeton University for a year and then became a professor there.His first book was published in 1932.In 1933, the Institute for Advanced Study was formed, and he became one of the 6 full-time people in the School of Mathematics (Einstein was one of the others). World War II hugely changed Neumann's areas of interest.Until 1940 he had been a great pure mathematician.During and after the war, he became one of the best mathematicians who put mathematics theories into practice.During the last part of the war he became interested in computing machines and made several contributions.After the war, Neumann continued his work with computers, and was generally very active in government service.He received many awards, was president of American Mathematical Society and was a member of the Atomic Energy Commission.He died in 1957 of cancer. Neumann really was a legend in his own time, and there are a number of stories about him.His driving ability is a part of this legend.He reported one accident this way: "I was driving down the road.The trees on the right were passing me in an orderly fashion at 60 miles per hour.Suddenly one of them stepped in my path."

mmlu_train_72295 | On Thursday October 3, Adam Harper decided to stop drinking coffee. Adam is a MBA student at Harvard University. He studies long hours, gets very little sleep and as a result, he drinks a lot of coffee---anywhere from five to six cups a day. Recently, Adam felt that drinking thus much coffee was making it hard for him to sleep at all. He also began having problems with his concentration , and complained of stomachaches. Adam's doctor made this suggestions: stop drinking coffee altogether. When Adam got up on October 3, he began his day without his morning coffee. By 11:00 a.m., Adam was in a terrible mood . He was tired and had a headache. At 11:30, he had a meeting with his student advisor. In the meeting, he found it almost impossible to continue. What was going on? Caffeine, a chemical found in coffee, was most likely the reason for how Adam felt. Caffeine is a stimulant that boosts energy levels and improves concentration- but only for a short time. Lowering caffeine consumption often causes a drop in blood pressure and the result is a "coffee headache", People who stop drinking coffee often say they feel tired and moody, and find it hard to focus. The good news is that these feeling usually pass after four and five days. During this time, doctors suggested taking some aspirin for the headache. So, if Adam can wait, in less than a week, he may be feeling much better. What happened to Adam on Thursday October 3? | [

mmlu_train_44303 | Zoo elephants don't live as long as those in the wild, according to a study sure to cause debate about keeping the giant animals on display. Researchers compared the life spans of elephants in European zoos with those living in Amboseli National Park in Kenya and others working on a timber enterprise in Buma. Animals in the wild or in natural working conditions had life expectancies twice than or more of their relatives in zoos. Animal care activists have urged in recent years to discourage keeping elephants in zoos, largely because of the lack of space and small numbers of animals that can be kept in a group. The researchers found that the _ life span for African elephants in European zoos was 16.9 years, compared with 56 years for elephants who died of natural causes in Kenya's Amboseli Park. Adding in those elephants killed by people in Africa lowered the median life expectancy there to 35.9 years. For the more endangered Asian elephants, the median life span in European zoos was 18.9 years, compared with 41.7 years for those working in the Burma Timber Enterprise. Median means half died younger than that age and half lived longer. There is some good news, though. The life expectancies of zoo elephants have improved in recent years, suggesting an improvement in their care and raising, but "Protecting elephants in Africa and Asia is far more successful than protecting them in Western zoos." There are about 1,200 elephants in zoos, half in Europe, researchers concentrated on female elephants, which make up 80 percent of the zoo population. One amazing thing was that Asian elephants born in zoos had shorter life spans that those brought to the zoos from the wild. Zoos usually lack large areas that elephants are used to in the wild, and that zoo animals often are alone or with one or two other unrelated animals, while in the wild they tend to live in related groups of 8 to 12 animals. In Asian elephants, baby death rates are two to three times higher in zoos than in the Burmese logging camps, and then, in adulthood, zoo-born animals die young. People are not sure why.

mmlu_train_78073 | The animal kingdom has a new member. On September 12, 2012, researchers made a report to the world that they discovered a new species of monkey. It is called the lesula. And it is only the second monkey species discovered in 28 years. Scientists first saw the lesula in June, 2007 in Congo, a country in Africa. The lesula lives in the rain forests. The monkey was first found as a pet in a local family. When researchers found it, the family told them that they caught the monkey in the wild and then kept it as a pet. The scientists have compared the lesula to the owl-faced monkey. The owl-faced monkey gets its name for having a long nose and a face that looks like an owl . The lesula and the owl-faced monkey are similar in size and both have a stripe on their nose. This shows the lesula and the owl-faced monkeys are close relatives, but different species.

For some, having to readjust to civilian life is one of the most challenging assignments our returning soldiers and marines will ever to undertake. While people may think readjusting should be simple, they must take into consideration all physical and mental stress our servicemen went through. Post-traumatic Stress Disorder , or PTSD, is a mental disorder that can occur following the experience or witnessing of life-threatening events such as military combat . Most survivors of trauma return to normal given a little time. In the military, the marines are given a two-week course on how to return to civilian life. Unfortunately, some will have stress reactions that do not go away on their own, or may even get worse over time. These individual may develop PTSD. People who suffer from PTSD have difficulty sleeping because they are often reliving the experience through nightmares and flashbacks, and feel deserted or often stand off, and these symptoms can be severe enough and last long enough to significantly damage the person's daily life.

mmlu_train_9982 | For many years, scientists have wondered how Chrysopelea paradisi, known as the "flying" snakes, can stay afloat as they leap from one tree to another, sometimes covering a distance of as long as 79 feet. Now a new study has explained that it may be all to do with the way they move. The report was published by Virginia Tech scientist, Jake Soeha who has been studying the flying snakes for a number of years. He began his research by first focusing on its launch technique. He discovered that the snakes first make themselves completely flat and then move side to side; they glide rapidly at a speed of between 26-33 feet per second, before leaping off. Once they take off, their bodies actually tilt at about a 25-degree angle to the airflow created by their flight. When they first leap, the snakes start to drop altitude to pick up speed. With the front of their bodies held stiff, they start a strange air-gliding dance, by moving from side to side. This turns their entire body into one big wing, allowing them to glide across long distances. The findings are not only exciting because they solve the puzzle of how the snakes are able to fly, but also because the same principles could be used to build small flying instruments. The flying snakes that are native to South and South East Asia spend most of their lives in trees in the lowland tropical forests. They grow between 2-3 feet long and are about as wide as a human finger. As would be expected, the smaller and lighter ones are more able to "glide" for longer distances than the bigger and heavier ones. They are not the only wingless animals that can fly -- there are flying frogs that use similar gliding techniques to make their way across forests. The best title for the passage is_. | [

"The message is that teenagers who use their cellphones excessively are much more stressed, much more restless, much more tired, and have a great tendency to develop sleep deprivation as a result of their calling habits, " said the study author Dr. Gaby Bader. He focused on the experiences of 21 healthy Swedish boys and girls between the ages of 14 and 20. The teens kept what the authors described as "regular working/studying hours" and were not previously diagnosed with any particular sleep irregularity. He observed that the above-15 call group kept more irregular sleeping hours than the lower-use group,had more difficulty falling asleep,more difficulty waking up,and experienced more sleep disruptions . Bader said that among young people,a ly recent technological invention like the cellphone has quickly become existed nearly everywhere,giving rise to considerable pressure to keep in touch. And this pressure can develop into an addiction,with serious negative results for teenager health. "We see more and more people--especially the young generation-- who grew up with these kinds of items and gadgets in their hands," Bader said. "And they become dependent on the technology. So,we have to teach young people to be structured. To know when to have the cellphone on,and when to switch it off. To avoid becoming the slave of technology,instead of the master. " Dr. Mary Carskadon expressed little surprise with the finding. " Interpersonal contact is one of the things that's best at keeping us awake," she observed. "And so,a young person receiving cellphone texts or phone calls is going to have more deep disturbances. And they are going to be tired and restless,and probably,as a result,going to use more stimulants .And judgment is not always the best in our teenage years.

mmlu_train_30807 | Password strength has been a topic about the Internet lately. I have seen lots of clever methods for generating and remembering strong passwords. Some are better than others, but in my opinion , none are adequate . Here's the problem : it doesn't matter how strong your passwords are if you use the same one on multiple sites. All it takes is for a site to get hacked , like Gawker media, or even Sony did , and now your super-strong password has been stolen , and every site on which you used that password has been accessed . So, the bottom line is that no matter how strong your passwords are , and no matter what clever tricks you use to help you remember them , if you surf the Internet often , the only truly secure password system is what you need . Enter LastPass. It's not the only password manager out there, but I like it the best. You create ONE strong password that you have to memorize and use it to access your LastPass database . The LastPass database is stored online, on LastPass's servers. LastPass recognizes the site you're on and automatically logs you in (after , optionally , asking you to re-enter your master password). LastPass also has automatic form fill and automatic password generation. This means that you can have a different , unique , very strong password for every site you log into , but you only have to remember one master password . It's the best of both worlds. One argument against LastPass is that if their database is attacked , then all of your sites are in danger, and that's true, but given that their entire line of work is keeping that information safe , I'm willing to take that chance. The alternative is rolling dice or picking phrase to create passwords, writing all of them down on a piece of paper or something , and then having to manually type them in when I go to a site . A terrible mess. There is a free version of LastPass , with additional features unlocked if you pay $ 12 for a year's subscription . ----Joshua Bardwell When using LastPass , users have to remember _ . | [

mmlu_train_13878 | In my long years of teaching, I often ask my students to read the texts until they can recite them, and I tell them that recitation is an important part of their homework. However, some of my students are tired of doing so, thinking that it is both hard and useless. They argue that it takes a long time to recite a text from memory and text itself never appears in a test paper. In my opinion, it naturally takes time to recite a text, but it is worth doing so. When you are able to recite a text, you are sure to be familiar with the words and expressions. When you need them in reading or writing or doing exercises, they will come to your mind quickly, and so you will give quick response to all kinds of language situation. How can we say that it is useless? Besides, many students complain that they soon forget what they were once able to recite. This is true, but you don't need to worry. While you are reading and forgetting the texts, your language level is being raised.

mmlu_train_35655 | "I drink caffeine to stay awake. It has positive effects on me. I'm healthy, and there's nothing wrong with me," said Sarah Green, a freshman, who consumes many caffeine drinks to stay awake in completing the many tasks in her busy schedule. Caffeine is known to have many positive and negative consequences, and now that there might be an additional positive effect may have been discovered. A study suggests that a skin lotion containing caffeine, which is also found in green tea, may reduce the risk of skin cancer. Two lotion tests were conducted on hairless mice that were exposed to high levels of ultraviolet radiation . As a result, the lotion reduced the number of tumors each mouse developed. Unlike sunscreen , the new lotion is applied after exposure to the ultraviolet rays. Rays from the sun can cause genetic changes in the skin that can lead to skin cancer. Caffeine obstructs this action and causes the diseased cells to kill themselves. "I know that caffeine has been found in certain drinks and it causes increased activity of the nervous system, and increased blood pressure on blood vessels . I don't know of any positive effects of caffeine," health teacher Montego Estes said. Caffeine, found commonly in tea, coffee and soft drinks, provides people with an increase in energy. Half of all American adults consume more than 300 milligrams of caffeine per day. Caffeine is addictive because it uses the same mechanisms as amphetamines , and cocaine and heroin to excite the brain. "This new cream doesn't sound to me as though it would work," junior David Bobbit said, "Caffeine seems to have more negative effects than positive ones." Skin cancer is the most common of all cancers in the US. About one million cases will be diagnosed in the country this year.
