mmlu_train_61244 | Desert plants fall into two sorts according to the way they deal with the problem of surviving drought. There are the drought--avoiders--those which persist only as seeds, ready to spring up when it rains, to flower quickly and produce another crop of seeds, and to die again. There are also the drought--resisters--those which have evolved various methods for strong water, locating underground water, or reducing their need for water by such devices as shedding their leaves. The drought--resisters are perennials ,they manage to live from one rainy season to another, slowly growing bigger and bigger. Of these, the succulents is a small but interesting fraction . They may store water in their leaves, in their stems, or in underground containers. In the American deserts the best--known succulents are the cacti . They come in a wide range of sizes, from 50--foot tall giant saguaros to tiny round cacti about the size of a thumb--nail. They take thick, cylindrical or even spherical forms, thereby exposing a minimum of evaporating surface to the air and light. They are leafless, except in youth, and then the leaves are small. Typically their surfaces are spiny, discouraging thirsty animals, and channeled like an accordion , so the fleshy stem may expand quickly when the plant drinks and contract slowly as it uses up the water. The root system is widespread and shallow, with good reason; only about 3 per cent of the rain that falls on the desert penetrates to any significant depth into soil. According to the passage, some desert plants drop their leaves _ . | [

Researchers found that just 6 per cent of us believe that" most people rely more on their dog than they do on their PC",while 67 per cent think the opposite to be true. Even 38 per cent of dog owners admitted to relying more on their PC than on their dog, although 36 per cent disagreed. And 71 per cent of 18 to 24-year-old dog owners said they relied more on their computer. Paul Allen,editor of Computeractive magazine said:"These days you can even you're your PC for fl walk,provided you have a laptop or tablet." "It's only a matter of time until the first PC that fetches your slippers." Researchers questioned 2,000 British adults to find out the change modern technology has brought to their home life.

mmlu_train_42994 | Older people who have low expectations for a satisfying future may be more likely to live longer, healthier lives than those who see brighter days ahead, according to new research "Our findings showed that being overly optimistic in predicting a better future was associated with a greater risk of disability and death within the following decade," said Frieder R. Lang, the leading researcher of the University of Erlangen-Nuremberg in Germany." Pessimism about the future may encourage people to live more carefully, taking health and safety measures." Lang and colleagues examined data collected from 1993 to 2003 for the national German Socio-Economic Panel, an annual survey on approximately 40,000 people from 18 to 96 years old. The researchers divided the data according to age groups: 18 to 39 years old, 40 to 64 years old and 65 years old and above. Through mostly in-person interviews, the participants were asked to rate how satisfied they were with their lives and how satisfied they thought they would be in five years. Five years after the first interview, 43 percent of the oldest group had underestimated their future life satisfaction, 25 percent had predicted accurately and 32 percent had overestimated , according to the study. The researchers calculated that each increase in overestimating future life satisfaction was related to a 9.5 -percent increase in reporting disabilities and a 10- percent increase in risk of death. Because a darker outlook on the future is often more realistic, older adults' predictions of their future satisfaction may be more accurate, according to the study. In contrast, the youngest group had the sunniest outlook. "We argue, though, that the analysis may depend on age and available resources. These findings shed new light on how our perspectives can either help us take action or prevent us from taking action that can help improve our chances of a long, healthy life," Lang said.

mmlu_train_39194 | Offering a powerful new tool against terrorism, researchers have found a way to detect lies in the liar's blushing face. The technique, described in the journal Nature, uses a thermal camera to detect the sudden shift of blood flow in the face. The system performed as a traditional polygraph , the scientists report. Pushed by technological advances and with fresh interest since Sept.11, the discovery is part of the development in the scientific study of detection. Although the lie remains a mysterious phenomenon, researchers in recent years have found a number of new methods that might take the place of the polygraph, from brain scans, to slight changes in eye movement, to sparks of electrical activity that signal a person has seen a victim or a crime scene before. The new finding says, when a person tells a lie, there is a sudden change of blood to the area around the eyes. Although the change is not ordinary visible, the blood warms the skin, causing bands of color1 to appear through a camera sensitive to heat. One advantage of the camera can provide answers quickly, and doesn't require a highly trained expert to operate it or explain its results. In theory, this new technology could be used anywhere large numbers of people need to be quickly screened. But some scientists say the technology would need to be improved before it is ready for use, for it is possible that there are other reactions that cause a sudden change in blood flow in the face and there is also the danger that people will learn to fool the machine, the same way they try to fool polygraph examiners by controlling their breathing or taking drugs to relax themselves.

mmlu_train_81502 | Space vegetables are grown from seeds that have been taken to space and brought back to the earth. The seeds are affected by the radiation and low gravity in space. When they are brought back to the earth, these seeds produce vegetables that are bigger and healthier than normal vegetables. However, some people worry about eating space vegetables. They think that space vegetables might not be good for us and could make us get sick because of the radiation in space. However, people should not be frightened because space vegetables are very healthy. Here are some facts that you should know about space vegetables. Space vegetables are grown from seeds that are carefully chosen. When seeds are brought back from space, they are tested to make sure that they will be safe to eat. Space vegetables are better for you than normal vegetables. For example, space tomatoes stay fresh for twenty days, which is one week longer than normal tomatoes. After genetically modified food appeared in the market, people worried that they were eating unknown things. For example, if nut genes are put inside potatoes, people allergic to nuts might get sick from eating these potatoes because they do not know they are also eating nuts.

mmlu_train_9347 | She might not be paid, but Carnegie Mellon University's newest staff member does all that a typical receptionist can do: give directions, answer the phone -- and even gossip about her life. University officials revealed what it considers to be the world's first robot receptionist with a personality of her own. The blond receptionist, named "Valerie," puts on a headset and interacts with people by talking about her boss, her psychiatrist and her dream. Valerie, the roboceptionist, sits in a custom-made booth at the entrance of a computer science hall. With her ability to distinguish motion, she greets visitors as they come near. Type in a question on a keyboard and she gives directions around the Pittsburgh campus and provides visitors information about the weather. More than that, she tells stories about her life. From her booth, passers-by often can hear her talking on the phone. She recognizes when someone is in front of her and remembers their characteristics. She can change between tasks from talking on the phone to answering a question. Valerie, however, does have her limit. She is a drum-shaped mechanical device with a digitally lively face that appears on a computer display. Visitors have to type on a keyboard to communicate with her. And she understands only simple questions. Eventually her creators would like to install face recognition so people don't have to insert an identity card for her to remember them. And people won't have to type their questions on a keyboard if they can solve the problem of voice recognition in a crowded hall. Valerie will tell the story of a robot living in a human world.

mmlu_train_20672 | The poorer mental function seen among alcoholics,many of whom also regularly smoke cigarettes,may be partly due to the long term effects of nicotine ,new research suggests. "People who are also smokers are at a much higher risk," Dr.Jennifer M.Glass of the University of Michigan's Addiction Research Center said. In her study,"Cigarette smoking has a bad effect on IQ and thinking," she said. This finding may seem counterintuitive ,since many smokers show that they feel quicker and focused after smoking. Indeed,research shows that improved mental functioning is one of the immediate effects of nicotine exposure. _ Studies show that up to 87 percent of alcoholics smoke cigarettes. Yet,few studies have looked into cigarette smoking as a factor that might explain the cognitive lack reported among alcoholics. To search for that association,Glass and her colleagues examined brain function among 172 men from the same area,including 103 men who abused alcohol. The team found that men with higher scores on the lifetime alcohol problems scale(LAPS)and those who reported a higher number of pack years of smoking both had lower IQ scores. Upon further research,the researchers found that smoking also appeared to be independently associated with weaker word and space reasoning. Thus,though smoking did not account for all of the decreased mental functioning observed among the alcohol abusers,it did seem to account for some of the effects,the report indicates. It can be inferred from the passage that . | [

mmlu_train_6695 | Remember, from the moment they are born, our children have the ability to know when they are hungry - and they cry to let us know too! Of course, they also cry to let us know they are wet, hurt, or bored, but we soon learn to tell the difference and try to meet each need somehow. When we begin to feed them solid foods, they let us know when they have had enough by turning away from the spoon - or refusing the food back at us! Why is it that once children are old enough to sit at the table their parents are often heard bargaining with them or threatening them to finish all their dinner? When we make our children eat up the plate that we filled, we don't pay attention to their born ability to know how much, and what, their bodies need. Instead, we should allow them to use their own hunger feelings to determine how much they need, while we provide a balance of nutritious and "fun" foods. When we teach them about moderation and set a great example by living an active, healthy lifestyle, they will be less likely to develop weight problems later in life. Think of your slim friend who eats whatever she wants -but will refuse ice cream if she has had enough to eat! "Eat all your dinner if you want dessert" translates to "you must overeat so I will reward you by letting you overeat some more!" By using sweets as a reward for good behavior, kids begin to believe sweets are really special and they may want them even more.

mmlu_train_44343 | Americans have developed an olive oil habit. Out to dinner recently, I saw a man dipping his white bread in olive oil and then pouring it all over his salad, saying, "Wow, this is so good for me!" But is olive oil the healthiest fat? No, it's not. You might ask, doesn't it lower cholesterol ? Well, only when you substitute olive oil in equivalent amounts for butter or oils that are higher in saturated fat. Olive oil doesn't lower cholesterol; it just doesn't raise it as much. You may be better off with canola oil. The 1999 Lyon Diet Heart Study found that a Mediterranean diet significantly reduced heart attacks and premature deaths. Many people attributed this to eating a lot of olive oil. But it was increased consumption of canola oil that accounted for these improvements. Also, study participants ate more whole-grain bread, vegetables, fish and fruit, and less meat. Butter and cream were replaced with man-made butter made from canola oil, which has more healthy omega-3 fatty acids than olive oil does. Another study found that olive oil reduced blood flow by 31%. Canola oil and fish oil don't. (You want to increase blood flow to all body parts.) I like the taste of olive oil, and I use it sometimes. It's a healthier fat than many others, but it's not nearly as healthy as canola oil -- or fish oil and flaxseed oil, for that matter, which also have lots of omega-3s. And a tablespoon of any oil has 126 calories. Think about that before you pour it on. According to the author, olive oil _ . | [

Bags for women have become bigger and heavier as designers combine briefcases with handbags and straps have become longer, resulting in many users complaining of neck, shoulder and back problems. "I see so many women with neck pains and headaches and what I usually do is look for their purse and pick it up,"said Jane Sadler, a family practice physician at Baylor Medical Center in Garland, Texas."We take it over to the scale and weigh it and usually they're anywhere from 7 to 10 pounds. We're really going to see women with more and more problems later on if we continue the big purse craze." William Case, a physical therapist in private practice in Houston, Texas, urged designers"to place a cute, educational caution tag on all bags to inform buyers of potential neck and shoulder dangers."Above all, he suggested correct posture while carrying big purses, keeping the head and shoulders upright. Patients should also often change the size and weight of purses carried. "The extra-large purses are quite extraordinary. They look beautiful when the women wear them, but I don't know how aware they are of the potential problems,"Case said. Placing objects on one shoulder was one of the least efficient ways of carrying a load, according to a professor from Cornell University in New York State."This causes a great imbalance,"he said."If a big bag is a fashion accessory, then occasional and symbolic use is fine.

Running, for example, may help to protect against heart disease and other health problems. Running may also help you live longer. Recently, researchers studied more than 55,000 adults. About a quarter of the adults have a good habit of running. The study found these runners were much healthier than non-runners. In fact, the runners lived, on average , three years longer than the non-runners. Running may be good exercise, but it can be difficult on the body. Here are commonly shared ideas among fitness experts to lower the risk of injury for people who are new to running. [?]Take it easy. Do not run too much, too soon or too fast. Most people get running injuries when they push themselves too hard. The body needs time to get used to increases in distance or speed. [?] Get good running shoes. There is no single best shoe for every runner. You should find the shoe that offers the best fit and support for your feet. More importantly, you should have a new pair of shoes every 500 to 800 kilometers. [?]Take good notes. Take time after each run to write down notes about what you did and how you felt.

mmlu_train_58014 | Three-dimensional printers are fast becoming everyday devices in the United States. Three-D printers are used to make everything from automobile parts to bone replacements for human patients. American research scientists are now working on creating replacements for living tissue. Researchers at the Medical University of South Carolina have been working on creating and manufacturing living tissue since 2003.This process is called biofabrication . It requires special printing equipment and a special kind of ink. Traditional printers require ink to produce an image or design on a piece of paper. For their three-D printer, the South Carolina researchers prepare complex nutritious solutions they call bio-inks. Bio-inks are made of proteins and glucose , which normally provides energy for most cells of the body. The researchers also add living cells taken from the animal that will receive the new, printed tissue. The bio-inks are then added to a device that researchers call the Palmetto bio-printer. Sarah Grace Dennis is one of the researchers at the Medical University of South Carolina. She says new technology, like the Palmetto bio-printer, is a great help to the biofabrication process. The bio-inks are placed in three dispensers , containers, inside the printer. Lasers control both the position of the printing surface and the places where the bio-ink is released. Michael Yost is a leader of the research team. He says the printing process is fully automated-- machine-operated. He says that the Palmetto bio-printer makes it possible to create complex tissue types. The researchers say bio-printing is still experimental. But they hope in a few years they may be able to print tissue to replace damaged human organs. But there are still some problems which need to be solved. Some scientists worry about how to get blood to the replacement tissue. The flow of blood is important to keep the printed tissue alive. Michael Yost hopes that more people will believe in the benefits of biofabrication. "Tissue biofabrication is a reality, and it is a reality now, and if you come here and you get to see it. You will get to see it. You can't touch it, but you will see it and think this is real. And this is really human." What can we know about the bio-inks? | [

mmlu_train_86760 | Nowadays, many children spend hours a day looking at computer screens or other digital products. Some eye care doctors say all the screen time has caused more children to have what they call computer vision syndrome . Nathan Warford is an optometrist in the US. He says he has seen more children having eye problems. "More children come into my office because their parents have noticed that they have headaches or red eyes, or because their degree of short-sightedness appears to be increasing very fast and they're worried," he said. Dr. Warford says part of the problem is that even if their eyes start to feel uncomfortable or they start to get a headache, some children don't tell their parents, because they don't want their games or the computer to be taken away. Another part of the problem is that people blink less often when they look at the screen.A person who uses a computer or a digital product blinks about a third as much as we normally do in everyday life.

mmlu_train_58100 | A new study suggests that early exposure to germs strengthens the immune system. That means letting children get a little dirty might be good for their health later in life. The study involved laboratory mice. It found that adult mice raised in a germ-free environment were more likely to develop allergies, asthma and other autoimmune disorders. There are more than eighty disorders where cells that normally defend the body instead attack tissues and organs. Richard Blumberg,who led the study,is a professor at Harvard Medical School in Boston,Massachusetts. He says,in 1989,medical researchers who sought to explain these diseases, first discovered that the increasing use of antibacterial soaps and other products, especially early in life, could weaken immune systems. Now, Dr. Blumberg and his team have what is the first biological evidence to link early exposure to germs to stronger adult immune systems. They say this exposure could prevent the development of some autoimmune diseases. In the adult germ-free mice, they found that inflammation in the lungs and colon was caused by so-called killer T cells. These normally fight infection. But they became overactive and targeted healthy tissue--an autoimmune condition seen in asthma and a disease called ulcerative colitis . Dr. Blumberg says the mice raised in a normal environment did not have the same reaction. He says their immune systems had been "educated" by early exposure to germs. Rates of autoimmune disorders are rising worldwide, but mostly in wealthier, industrialized countries. According to Dr. Blumberg, it might be high time that people were warned to be more careful with the early use of antibiotics and the prescription from their doctors. Rob Dunn is a professor of ecology and evolutionary biology at North Carolina State University in Raleigh. He says the new study does not mean people should stop washing. "Wash your hands , but don't do it with antibacterial soap. Let your kids play in a reasonable amount of dirt and get outside and get exposed to a diversity of things", says Rob Dunn. Why are germ-free mice easy to develop lung inflammation? | [

mmlu_train_66197 | "Eat local." It's one way to reduce human effect on the planet.Eating local means to try to buy and consume foods that are grown in places close to home.However, most of the food sold at supermarkets is not locally grown or produced.Trucks and planes deliver these foods from hundreds or thousands of miles away.During the transportation, greenhouse gases are produced, causing global warming.So the shorter the distance your foods must travel, the less the harm is done to the environment. But how do you get local food if you live in a large city, hundreds of miles away from farms?Environmental health scientist Dickson Despommier and his students came up with the idea of a "vertical farm". A vertical farm is a glass-walled structure that could be built as tall as a skyscraper.Since the garden is built upwards, rather than outwards, it requires much less space than an ordinary farm.The world is quickly running out of room for ordinary farming.Vertical farms could be a key to this situation.Despommier imagines a 30-story building with a greenhouse on every floor.The walls of the building would be clear, to allow crops to get as much sunlight as possible.Depending on a city's water resources, Despommier thinks hydroponic farming is another method for the vertical farm which needs no soil to grow plants. Despommier says the hydroponic greenhouses would use a system that would use a city's waste water and fill it with nutrition to make the crops grow.If this method works, it would provide food to a city and save millions of tons of water. The idea of a vertical farm has attracted the attention of government officials around the world.Scott Stringer, a government official from New York City, thinks the city is suitable for the vertical farming."Obviously we don't have much land left for us," Stringer said, "But the sky is the limit in Manhattan." Despommier admits that there is still a lot of work to do to make vertical farms a reality."But I think vertical farming is an idea that can work in a big way." he says. Why are people advised to eat local? | [

But now that the environment is cleaner , the foxes have come home , one of the many wild animals that have moved into urban areas around the world . Several changes have brought wild animals to the concrete jungles . First of all , air and water quality in many cities has improved as a result of the 1970s' pollution control efforts . meanwhile , rural areas have been built up , leaving many animals on the edges of suburban areas . In addition , conservationists have created urban wildlife shelters . " The number and variety of wild animals in urban areas is increasing , " says Gomez Jones . One of the country's largest populations of raccoons now lives in Washington , D.C. , and moose are regularly seen wandering into Maine towns . Peregrine falcons dive from the window edges of buildings in the largest U.S. cities to hunt for pigeons . For peregrine falcons , cities are actually safer than rural areas . By 1970 the birds had died out east of the Mississippi because the DDT , a widely used poison to kill insects , had made their eggs too thin to support life . That year , Tom Cade began raising the birds for release in cities , for cities afforded abundant food in the form of pigeons and contained none of the peregrines' natural enemies . " Before they died out , some migrated to cities on their own because they had run out of natural habitats , " Cade says . " To peregrines , buildings are just like natural habitats .

Before your eyes start rolling, listen up: teens are using social networking sites for more than just gossip, according to a new study by the National School Boards Association. The students who took part in the online survey, aged 9 to 17, said they spent almost as much time on social networking online as they did watching television. And it is what these kids are talking about online that is causing such a cheer: education. Of the students who took part in the study 60 percent reported that some of the most popular social networking topics were college planning, learning outside of school, careers, and schoolwork. They also reported posting writing and art projects that might have nothing to do with schoolwork. Ann Flynn, director of education technology for the National School Boards Association, says social networking tools into educational is the way forward. Flynn says a school in Cleveland, Ohio is posting students' book reports on a blog for students of their own ages, parents and other teachers to read and comment on. "If someone reacts other than the teacher, a child is much more likely to take an assignment seriously," Flynn says. Not only students but also parents can benefit. Now parents can go online and know what the class is doing. So, next time your child says her blog is educational, get curious, sit down and check out the blog with her. You might just learn something new yourself. How does the school in Cleveland mentioned in the text use social net-working sites? | [

mmlu_train_35931 | Autumn blues? Let the sunshine in falling leaves, flowers, and cold winds. For many people late autumn can be a season of depression. Those who suffer from " the autumn blue" are often extremely tired, lack energy, need more sleep, feel increased appetite and gain weight. "The exact cause of this condition, often called seasonal depression or seasonal affective disorder (SAD), is not known yet," says Chen Jue, associate professor at Shanghai Mental Health Center. "But recent studies indicate that weather change is influential and strongly suggest that this condition is caused by changes in the availability of sunlight." One theory is that with decreased exposure to sunlight, the biological clock that regulates mood, sleep, and hormones is delayed, running more slowly in winter. Exposure to light may reset the biological clock. Another theory is that brain chemicals that transmit information between nerves, called neurotransmitters (for example, serotonin), may be altered in individuals with SAD. It is believed that exposure to light can correct these imbalances. "It is a sad season, but you can try to make it happy. Remember, spring always lives in your heart," Chen says. "Going outdoors to get some sunlight may reduce the tension that brings you the low spirits. Relax at work. Stretch, breathe deeply. Take a tea break. Think of your next vacation. Color treatment also works in handling low mood. Music also plays a role in treating autumn blues." Which of the following CAN'T you do in order to deal with autumn blues? | [

mmlu_train_25831 | A new study suggests that the more teenagers watch television, the more likely they are to develop depression as young adults.But the extent to how much TV may be to blame is a question that the study leaves unanswered. The researchers used a national long-term survey of adolescent health to look into the relationship between media use and depression.They based their findings on more than 4,000 adolescents who were not depressed when the survey began in 1995. As part of the survey, the young people were asked how many hours of television or videos they watched daily.They were also asked how often they played computer games and listened to the radio. Media use totaled an average of 5 and one half hours a day.More than 2 hours of that was spent watching TV. 7 years later, in 2002, more than 7 percent of the young people had signs of depression.The average age at that time was 21. Brian Primack at the University of Pittsburgh medical school was the lead author of the new study.He says every extra hour of television meant an 8 percent increase in the chances of developing signs of depression. The researchers say they did not find any such relationship with the use of other media such as movies, video games or radio.But the study did find that young men were more likely than young women to develop depression given the same amount of media use. Doctor Primack says the study did not explore why watching TV causes depression.But one possibility, he says, is that it may take time away from activities that could help prevent depression, like sports and socializing. It might also affect sleep, he says, and that could have an influence. The study was just published in the Archives of General Psychiatry. In December, the journal Social Indicators Research published a study of activities that help lead to happy lives.Sociologists from the University of Maryland found that people who describe themselves as happy spend less time watching television than unhappy people.The study found that happy people are more likely to be socially active, to read, attend community services and to vote.

mmlu_train_12021 | One morning, Tina and Wesley both wake up with sore throats and stuffy noses. They have the same symptoms, but they react very differently. While Tina reaches for water and vitamins, her husband, Wesley, reached for the phone. "I'd better make a doctor's appointment," he says. Why do these two Chinese people react to sickness so differently? Tina grew up in the U.S. Wesley grew up in Taiwan. And they have discovered that differences between Chinese and American cultures extend to every area of life. Even sickness and health. When Westerners experience pain, they usually express their discomfort. Most Asians don't. This creates a challenge for American nurses who care for Asian patients in the U.S. How do they know if that calm, quiet patient is really hurting? They have to keep asking their Asian patients how they feel. In addition, Americans usually don't want sickness to slow them down. Unlike Chinese people, Americans often don't take time off work to rest and get well. They'd rather sneeze and cough all day at the office. Americans who get sick in Asia may protest when Chinese friends suggest they go to the hospital. "I'm not that sick!" they may say. In the U.S., only very sick or injured patients go to hospital. People go to a doctor's office for less serious problems. Like Tina, Americans more often turn to vitamins or over-the-counter drugs to help them get well. Chinese people, however, often head straight for the doctor when they get sick, like Wesley did. They want a prescription to treat their sickness before it gets serious. Chinese patients often just trust their doctors to give them the information they need. Most Americans, however, ask their doctors lots of questions and do research. American patients want to know everything they can about their condition. So, are one culture's attitudes toward health better than the other's? Perhaps not. Tina and Wesley will both recover from their colds. And today, doctors all over the world are sharing treatment methods with each other. In health, as in everything else, we can learn a lot from each other. Why do American nurses find it difficult to care for Asian patients? | [

Well, you may be wrong. Tetsuro Matszawa, a scientist from Kyoto University, Japan has showed how chimps have far better memories than humans. "We learn that chimps have great memories by doing tests," he told The Guardian "You can do things to improve your memory." How do chimps have better memories than us? Scientists tested four chimps and human volunteers. They showed them five numbers on a computer screen. Chimps and human volunteers had to remember the numbers correctly. But to make it hard, the numbers disappeared after seven tenths of a second. Then they will reduce the time to two tenths of a second. While humans began to make mistake after mistake, the young chimps still did very well. Why do they have better memories? We share 98.8 percent of our DNA with chimps. But during evolution , we lost some of our shared abilities. As humans learned new skills, like language, we had to lose some of our memory skills to make room in our brains.

The food tastes good and warm, and a family meal brings everyone together. In some families, meals are often the only times everyone sees one another at the same time. Another reason people enjoy home cooking is that it is often a way of showing love. A parent who makes some cookies is not just satisfying a child's sweet tooth. She or he is sending a message. The message says, " I care about you enough to send an hour making cookies that you will eat up in 15 minutes if I let you." A parent spends an hour making cookies _ . | [

mmlu_train_40380 | There are 115 distinct species of pine trees with 35 native to North America. Pines are defined as evergreens with long, needle-like leaves and are only native to the northern hemisphere. Pine trees are an adaptable and tough species that can survive in many conditions where other plants cannot. The average pine is 45 to 60 feet tall, but some are nearly twice as high. Western White Pine The western white pine grows the tallest of any pine tree, reaching up to 110 feet in height. They have blue-green needles arranged in bundles of five and produce a long cone . Bristlecone Pine The bristlecone pine grows slowly, reading about 20 feet tall. It is one of the oldest species of pine. Mexican Pine The Mexican pine can grow to 50 feet tall, with long, slender needles that drape off it like a weeping willow . Often nicknamed the "willow pine", it is native to Mexico. Its leaves can droop up to 12 inches long. Sugar Pine The sugar pine is another of the large pine species, such as the bull pine, but it also has the largest cones of any pine species, at 10 to 20 inches long. It grows from Oregon to California and is often used for construction. Jack Pine The jack pine is one of the smallest species of pine with rare leaves. Compared with the pines mentioned above, it doesn't seem to belong to the family. It is considered a member of the scrub-pine family; it prefers sandy soil.

The noise can be the sound of a jet airplane or machines in factories of loud music or other common sound at home and at work. A person only needs to hear the noise for little more than one second to be affected. An American scientist has found that using aspirin increase the temporary hearing loss or damage from loud noise. He did an experiment using a number of students at a university who all had normal hearing. He gave them different amounts of aspirin for different periods of time, then he tested their hearing ability. He found that students who were given four grams of aspirin a day for two days suffered much greater temporary hearing loss than those who did not use aspirin. The hearing loss was about two times as great. The scientist said millions of persons in the U.S. use much larger amounts of aspirin than were used in his experiment.

You should also avoid watching soap operas, spending time with people who complain or follow fat-free diets, according to a new book on getting "brain-fit". Many of the suggestions in Teach Yourself Training Your Brain are surprising. The book says to read out loud while holding a baby. Writers Terry Horne and Simon Wootton say their advice is from the latest research by experts around the world. "For years we have thought our brain capability is decided by our genes . But it's now clear that it depends on our lifestyle. What we eat and drink, how we learn at school and what type of feelings we have are all important," said Horne. The book talks about the most up-to-date thinking in science about how diet, the environment, stress and other sides of modern life affect our brain capacity. It also offers advice and exercises. _ Horne believes that people need to make changes to their lifestyles to increase their brain capacity Happiness, confidence and an optimistic nature help the brain, he added.

mmlu_train_82633 | The dodo was a ground nesting , flightless bird. An adult dodo could grow to a height of about a meter and weigh between 45-50 pounds. The natural habitat of this kind of bird lay in the forest of Mauritius. Seed and fruits that were found in the forest were the main food of the dodo birds. As they could easily get the food they required in the forest, they didn't need to fly. As time went by, they finally lost the ability to fly. It turned out to be a major disadvantage for dodos, as they were left with no ability to protect themselves against human beings' attacks in their natural habitat, which drove this kind of bird to extinction . The extinction of the dodo started in 1505, when Portuguese sailors set their foot on the Island of Mauritius. Before this, the dodo didn't face any danger. People began to hunt them. It was not long before animals, like cats, pigs and monkeys, were also introduced to the island by humans. When ships arrived, the rats on these ships came onto the land. Though these animals were not able to attack huge dodos, it was easy for them to attack dodos' nests on the ground. These animals continued to feed on dodo eggs. The dodo became a relatively rare bird in Mauritius at the beginning of the 17thcentury, and became extinct in the end. The last reported sighting of a dodo was in 1681. Why did the dodo lose its ability to fly? | [

They seem to enjoy meat, vegetables, fruit, milk and rice. Bears are not quite dangerous as people imagine them to be. Like most animals, they will try to stay away from human beings. However, bears are not weak animals. Sometimes they kill hunters, for they can be very dangerous. Bears have a good sense of smell but they have poor eyesight. They are also hard of hearing but they are very clever. They feed mainly on roots, frogs, fish and also small insects. They will sometimes kill deer and other large animals, but they seem to like small animals better. In the cold area, bears hibernate, or go to sleep from October to April. Before they start to hibernate, they eat a lot and store fat. The mother bear has its babies, usually two, towards the end of hibernation.

Tune in to the National Geographic Channel to find out about the discoveries they're making in the series My Brilliant Brain. When Marc Yu was only two years old,he began to play the piano. After a year, he started learning pieces by Beethoven. Now he's a world-famous concert pianist at age eight. He learns newer and more difficult pieces with ease and can identify any note he hears. He seems to be specially designed for music. In Born Genius, National Geographic looks at the science behind child prodigies to explain why some children seem to be born without limits. _ His came only after he nearly died from bleeding in his brain. After recovering, McHugh's head was filled with new thoughts and picture. So, he began to express them in the form of poetry and art. Now, he's a seemingly unstoppable creative machine. Suffers of brain injury have shown that great mental ability can sometimes come from damage or disease. Accidental Genius explores this puzzling relationship. Can normal people be trained to be geniuses? Susan Polger has shown no sign of extraordinary intelligence. Yet, during her childhood, she studied thousands of chess patterns and learned to recognize them immediately. As a result, she was able to beat skilled adult players by age 10 and can now play up to five games at the same time without even seeing the boards. Make Me a Genius examines what is takes to turn an ordinary brain into that of a genius. If becoming a genius were easy, we'd all be done. Yet, there is much more to super intelligence than simply being born lucky. Learn more about amazing brains this month on National Geographic's My Brilliant Brain. The passage may come from _ . | [

mmlu_train_44297 | American researchers have found that variations in a single gene can be used to predict if someone is likely to take their own life. Researchers at John Hopkins University, in Baltimore, Maryland, found that the gene SKA2 stopped functioning correctly in people at risk of suicide. The SKA2 gene is found in the prefrontal cortex of the brain, and is involved in preventing negative thoughts and controlling abnormal behavior. If there isn't enough SKA2, or it is changed in some way, the body cannot control levels of cortisol . Previous research has shown that people who attempt suicide or who take their own lives have large amounts of cortisol in their systems. A test could allow doctors or psychologists to place patients on "suicide watch" and disable their access to drugs or equipment which they could use to end their own life. The research was reported in The American Journal of Psychology. "We need to study this in a larger sample but we believe that we might be able to monitor the blood to identify those at risk of suicide. After all, suicide is a major preventable public health problem, but we have been stymied in our prevention efforts because we have no steady way to predict those who are at increased risk of killing themselves," says study leader Dr Zachary Kaminsky, an assistant professor of psychological and behavioral sciences. "With a test like ours, we may be able to cut down suicide rates by identifying those people and intervening early enough to head off a catastrophe ." The blood test managed to predict those with the most severe risk of suicide with 90 per cent accuracy. They could also spot if someone had already attempted suicide with 96 per cent accuracy, simply by looking at the levels of SKA2. What's the purpose of the blood test? | [

mmlu_train_19521 | We are naturally drawn to friends and colleagues with familiar voices, scientists have found.People prefer those who have a similar accent,intonation and tone of voice to themselves , they discovered. Previous research has focused on how masculine or feminine a voice sounds.Men with deeper voices and women with slightly higher voices were thought to sound more attractive,because they suggest a bigger or a smaller body. But the new study,published by a linguistics expert in Canada,suggests there is a more complex mechanism at play.Dr Molly Babel, from the University of British Columbia in Canada, said,"The voice is an amazingly flexible tool that we use to construct our identity.Very few things in our voices are changeless,so we felt that our preferences had to be about more than a person's shape and size.'' She recorded 30 volunteers' voices and asked each to rate the others' attractiveness on a scale of one to nine.Each participant was from western America,with similar accents.The people we assessed were all in the same dialect group,but they showed that dialect to different degrees. "We seem to like people who sound like we sound,we like people who fit within what we know,"Dr Babel said.She also found that breathy voices in women-typified by the famous American actress Marilyn Monroe-were seen as more attractive. The breathy tone,caused by younger and thinner vocal cords ,implied youthfulness and health A creaky voice,suggesting a person has a cold,is tired or smokes,was seen as unattractive.The participants preferred men who spoke with a shorter average word length and deeper voices. The linguist,whose work is published in the journal PLOS One,said,"Once you're outside of a certain range of familiarity,novel and exotic sounding voices might become more attractive.We also have to keep in mind we find some accents more preferable than others because of social fixed ideas."

mmlu_train_42006 | The olinguito is new to science. Although lt has been living in the cloud forests of South Amcrica for some time. Scientists say the olinguito is the first new carnivore discovered In the Americas in more than 30 years. It is a hairy orange-brown creature with a sweet face and big eyes The animal has small. rounded ears and lives in the trees An adult weighs one kilogram and measures about 75 centimeters. with half of those centimeters taken up by its ringed tail Most of the time. it likes to eat fruit, although it also eats meat. Active at night, the animal has lived in Colombia and Ecuador for a long time. But the olinguito did not exist in science books before now. Kristofer Helgen, director at the National Museum in Washington, led the research team that confirmed the existence of the olinguito. It had been mistaken more than a century ago for a look-alike animal -- a similar but larger olingo . Mr. Helgen had been studying olingos in a museum for ten years. At that time. he observed a difference in the size and shape of the heads and teeth. That led him on an effort to prove he was looking at an animal never before described by science. He got lucky when he communicated with a zoologist in Ecuador. The animal expert there made a short video that shows an olinguito in the trees. The video confirms that the oiinguito is different from the olingo Mr. Helgen says tens of thousands of olinguitos live in the wild and are not in danger of disappearing forever. Human beings, however, are moving closer to the olinguito habitat in the Andean cloud forests. The research team estimates that 42 percent of historic olinguiio habitat has been removed Comparcd with most carnivores. the olinguito may seem more _ . | [

More than 15 percent of Chinese youths have been found with mental problems and about 30 million young people under 17 are suffering from depression,the Shanghai-based Wenhui Daily reported.The World Health Organization estimates that before 2020,the rate of children with mental problems will increase to 50 percent ,and mental problem will become a major factor behind deaths and illness in the young worldwide. Dang Xianhong,the spokesperson for the Beijing Municipal Health Bureau,said rapid social change is one of the reasons behind the rising number of youngsters with psychological problems.If these mental dispenses are not addressed on time, science of crimes,drug-taking and other dangerous behaviors are expected to rise.Experts said mental diseases could be caused by many factors,such as the inability to handle interpersonal relations well, unstable emotions and pressures from an overload of studies.A number of experts have also said the one child policy is another reason leading to poor mental health in the young.Children are said to be too "spoiled" and "selfish" in a one child family. It's reported that schools in many cities are rolling out measures to help students maintain their mental well-being.Yin Jingmiao, a teacher of the Beijing No,105 Middle School,told China Daily that the school invites psychologists to provide counseling to students three times a month."Students can be arranged to have 40-minute counseling sessions."

mmlu_train_7551 | Look, this is the first plane in the world to be created using the new technology of "3D printing". The airplane was built using only a computer--but it can fly at a speed of 100mph and has a two-meter wingspan. It was produced using a special nylon laser printer that builds up something layer-by-layer. The parts were made separately and attached using a "snap fit" technique so the aircraft could be put together without tools in minutes. No fasteners at all were used in the manufacture of the plane. Unmanned and electrically powered, the plane can travel in near silence and is also equipped with a small autopilot system. The special production process used is known as "laser sintering "and allows the designers to create shapes and structures that would normally include costly manufacturing techniques. This technology allows a highly-tailored aircraft to be developed from your own design to first flight in days, while using traditional materials and techniques would take months. And because no tooling is required for manufacture, major changes to the shape and scale of the aircraft can be made with no extra cost. Professor Jim Scanlon, who led the team, said, "The process allows the design team to revisit historical techniques and ideas that would have been too expensive using traditional manufacturing." He added, "This form of structure is very firm and lightweight, but very complex. If it was manufactured traditionally it would require a large number of individually tailored parts that would have to be connected or fastened at great expense." The new printed plane is known as the Southampton University Laser Sintered Aircraft--or SULSA for short--and is part of a wider project using cutting-edge manufacturing techniques. The University of Southampton has been at the leading position of Unmanned Aerial Vehicle development since the early 1990s. This kind of plane has the following advantages EXCEPT _ . | [

mmlu_train_56579 | If you live in the U.S., you're probably used to throwing banana peel into the trash. But people in other countries, including India, have been taking advantages of their nutritional benefits for many years. While the flesh of a banana is soft and sweet, the skin is thick, hard and slightly bitter. To eat the peel, you can fry, bake, or boil it for at least 10 minutes. Also, the riper bananas get, the thinner and sweeter banana peel will become. That's because of a natural plant hormone called ethylene that fruits release as they ripen. Ethylene interacts with the sugars and fiber in the banana skin, changing complex sugars into simple sugars and breaking down pectin, a form of fiber in bananas that keeps them stiff. That's why the older your banana is, the flimsier it feels. The sweet flesh of a medium-sized banana contains great percentages of your daily recommended intake of various nutrients, such as: *12% of your daily fiber, which helps with digestion and may help lower your risk of diabetes *17% of your vitamin C, which is important for your immune system as well as your growth *20% of your vitamin B6, which aids the body's ability to turn food into energy *12% of your potassium, which helps with the development of cells, tissues, and organs throughout the body If you eat the skin along with the flesh, you will get an even bigger increase in these same nutrients. Eating the peel is not only good for your body but also better for the earth. The average American ate 11.4 pounds of bananas in 2014. Since a medium-sized banana weighs about 0.3 pounds, that equates to about 38 bananas per person, or about 12 billion for the whole of the U.S. And since most of us throw away the peel, that also means a lot of organic waste.

However, special care must be taken in selecting new blood for you. If the blood is too different from your own, the transfusion could kill you. There are four basic types of blood; A, B, AB, and O. A simple test can make sure of a person's blood type. Everybody is born with one of these four types of blood. Blood type, like hair color1 and height, is received from parents. The four groups must be transfused carefully. A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. O can give to any other group; therefore, it is often called the universal donor . For the opposite reason, AB is sometimes called the universal recipient . However, because so many reactions can happen in transfusions , patients usually receive only salt of plasma (liquid part of blood) until their blood can be matched as exactly as possible in the blood bank of a hospital.

mmlu_train_40590 | Scientists have discovered a special biological behavior in dolphins that could lead to a treatment for late-onset diabetes in humans. Studies on dolphins found that healthy dolphins switch into a diabetic-like state overnight when they are not feeding, but return to normal when they eat the following morning. The extraordinary finding has led scientists to suggest that dolphins have "genetic switch" that allows them to imitate diabetes while they are not feeding for a night, without suffering any ill effect. If researchers can identify a similar genetic pathway in human, they may be able to develop drugs to effectively switch off diabetes. Some 2.2 million people in Britain have type 2 (or late-onset) diabetes, a figure that is expected to reach 4 million by 2025 as a consequence of rising levels of obesity . The tissues of people with type 2 diabetes have become resistant to insulin so they lose the ability to control sugar levels in their blood. The condition can damage the heart, eyes, kidneys and nerves and contribute to 5% of all deaths, according to the World Healthy Organization. Dolphins appear to imitate diabetes to keep high levels of blood sugar when food is rare. Like humans, dolphins need some sugar in their blood for their brains to function normally. Venn-Watson's team analyzed 1,000 blood samples from 52 dolphins while they didn't eat anything overnight and fed in the morning. At night time, the dolphins' metabolism changed greatly and showed similar characteristics to that seen in people with type 2 diabetes. "It is our hope that this discovery can lead to new ways to prevent, treat and maybe even cure diabetes in humans," said Stephanie Venn-Watson, director of clinical research at the National Marine Foundation in San Diego.

mmlu_train_66952 | When talking about colds, maybe some people say it is very common. During the cold winter days, many people will complain the cold winter makes them catch a cold, and what they feel upset are not only the headache, cough but also the runny nose. It is so embarrassing when they forget to take a handkerchief or tissue along with them. Want to stay away from colds? Put on a happy face. Compared to unhappy people, those who are cheerful and relaxed are less likely to suffer from colds, according to a new study. It's possible that being happy helps the body fight illnesses, say the researchers from New York University. "It seems that positive feelings may reduce the danger of illness," said the study's chief researcher Sheldon Cohen. In an earlier study, Cohen found that people who were cheerful and lively caught coughs and colds less often. People _ were also less likely to tell their doctors that they felt ill. In this study, Cohen has interviewed 193 adults every day for two weeks. During the interviews, the people told researchers that they were given colds by doctors and had to stay alone in a room for six days. The results showed that everyone in the study was equally likely to get ill. But for people who said they felt happy during the research period, their illness are less serious and lasted for a shorter time. Cohen believes that when people experience positive feelings, their body may produce a chemical that helps fight illness and disease. So if you are worried about your health, look on the brighter side more often. What did the study find? | [
"People who felt happy never got ill.",
"People's feelings didn't influence their health.",
"People with good feelings became ill more easily.",
"People with positive feelings had less serious illnesses."
