mmlu_train_65354 | Learning disabilities are very common. They affect perhaps 10 percent of all children .Four times as many boys as girls have learning disabilities. Since about 1970, new research has helped brain scientists understand these problems better. Scientists now know there are many different kinds of learning disabilities and that they are caused by many different things. There is no longer any question that all learning disabilities result from differences in the way the brain is organized. You cannot look at a child and tell if he or she has a learning disability .There is no outward sign of the disorder .So some researchers began looking at the brain itself to learn what might be wrong. In one study ,researchers examined the brain of the learning-disabled person who had died in an accident .They found two unusual things. One has something to do with cells on the left side of the brain ,which control language. These cells normally are white .In the learning-disabled person, however ,these cells were gray. The researchers also found that many of the nerve cells were not in a line the way they should have been .The nerve cells were mixed together. The study was carried out under the guidance of Norman Geschwind, an early expert on learning disabilities. Doctor Geschwind thought that learning disabilities resulted mainly from problems on the left side of the brain .He believed this side of the brain failed to develop normally .Probably ,he said ,nerve cells there did not connect as they should .So the brain was like an electrical device in which the wires were crossed. Frank Duffy experimented with this technique at Children's Hospital Medical Center inprefix = st1 /Boston. Doctor Duffy found large differences in the brain activity of normal children and those with reading problems. The differences appeared throughout the brain. Doctor Duffy said his research proves that reading disabilities result from damage to a wide area of the brain, not just the left side. According to the passage we can conclude that further researches should be made to_. | [

mmlu_train_28703 | The physicians in a hospital form the center of medical staff. But they could not provide effective medical care to their patients without the help of numerous other medical employees. From the viewpoint of the patients, the nursing staff is particularly important. Nurses are usually in close contact with patients as long as they are in the hospital. A nurse does not study for as many years as a doctor. however, each must be equally dedicated. Caring for sick persons requires a great deal of patience and concern. Most nurses work long days, and they often must work at odd hours or during the night. Under the supervision of the head nurse, the nursing staff must provide nursing services on a 24-hour basis and attend to patients' needs. This responsibility continues around the clock, and so nurses must work in shifts. A shift is a period of duty, usually eight in length. The nurses on the ward rotate their shifts. Some take turns working night duty; others work odd shifts. A nurse must always be alert. She can never afford to be careless. This is true in all nursing situation, but it is especially true in the intensive care unit. Patients under intensive care are critically ill, and they must be monitored at all times. The nurses who do intensive care duty have one of the most demanding jobs in the hospital. Serving as a nurse can be a very rewarding job. But it is not an easy one. Not every person is suited to become a nurse. Only very dedicated people have chosen nursing as a profession. Why don't nurses study for as many years as doctors? | [

mmlu_train_41815 | Student Services Students' Union Every University has a Students' Union. If students are the lifeblood of a university, the Union is surely its beating heart. For students, by students A Students' Union is run by students and acts independently. At the end of each academic year, it will find six students to hold a sabbatical position managing the Union for the coming year. That the six successful sabbatical officers have only recently experienced issues affecting students ensures that your needs are very well understood. Letting your hair down Although the University is spread across a fairly wide area, the Union is centrally located and is only a short walk from any of the main buildings. This makes it very easy to catch up with friends who might be on a different course. At night, the place really comes alive - we have three different bars to suit every occasion. The venues are student-only so you can be sure of meeting people with a similar outlook and we throw in a transport service to make sure you get home safely. The Union also organizes various formal balls throughout the year, with the highlight being the end-of-year ball. Supporting you Beyond having fun, we also make sure some of the more serious issues are effectively dealt with. If you have a problem with your course, another sabbatical officer is trained to help you. Being independent from the University means we can represent and support you to the best of our ability, and once you reach university you may find that you become aware of more national or political issues. From the passage, we can learn that _ is the most wonderful program of every year. | [

mmlu_train_17350 | The virus "Ebola" is named after the Ebola River in what is now the Democratic Republic of the Congo. That's where the virus was discovered in 1976. A person can only get Ebola through direct contact with an infected person's bodily fluids, for example, sweat or spit. Additionally, the virus can get into your body through your eyes and mouth if those areas come into contact with something that contains the bodily fluids of an infected person. That's why health care workers are supposed to keep themselves completely covered while treating patients. The deadliest Ebola outbreak is spreading fast in Western Africa, taking over 900 lives so far. The health systems in Guinea, Sierra Leone and Liberia are severely lacking in resources, and health care workers may not have access to adequate protective clothing when working in rural clinics, where the proper protections are lacking. Since Guinea, Sierra Leone and Liberia share a border; it's easier for people to move from one country to another, increasing the risk for disease spread. For now, all doctors can do is treat the symptoms and provide supportive care like monitoring heart rate, blood pressure, and breathing while making sure the patients' fluids are supplied. Sometimes patients are given antibiotics to treat other possible infections. The hope is to make the patient pull through the infection so their immune system can eventually clear the virus. The people who survive Ebola have created enough antibodies to kill it. There are several promising drugs and vaccines in development, but since Ebola is less common--and research about it is not well funded -- there is no drug or vaccine that has been approved for use in humans. Many of the other drugs and vaccines have not yet been tested in humans. The WHO (World Health Organization) is meeting next week to discuss whether experimental treatments should be used during this outbreak.

mmlu_train_45919 | A study of a million UK women, published today in The Lancet, has shown that happiness itself has no direct effect on mortality, and that the widespread but mistaken belief that unhappiness and stress directly cause ill health came from studies that had simply confused cause and effect. Life-threatening poor health can cause unhappiness, and for this reason unhappiness is associated with increased mortality. In addition, smokers tend to be unhappier than non-smokers. However, after taking account of previous ill health, smoking, and other lifestyle and socio-economic factors, the investigators found that unhappiness itself was no longer associated with increased mortality. The lead author, Dr Bette Liu, now at the University of New South Wales, Australia said: "Illness makes you unhappy, but unhappiness itself doesn't make you ill. We found no direct effect of unhappiness or stress on mortality, even in a ten-year study of a million women." As in other studies, unhappiness was associated with deprivation, smoking, lack of exercise, and not living with a partner. The strongest associations, however, were that the women who were already in poor health tended to say that they were unhappy, stressed, not in control, and not relaxed. The main analyses included 700 000 women, average age 59 years, and over the next 10 years these women were followed by electronic record linkage for mortality, during which time 30 000 of the women died. After allowing for any differences already present in health and lifestyle, the overall death rate among those who were unhappy was the same as the death rate among those who were generally happy. The study is so large that it rules out unhappiness being a direct cause of any material increase in overall mortality in women. This was true for overall mortality, for cancer mortality, and for heart disease mortality, and it was true for stress as well as for unhappiness.

mmlu_train_49365 | Scientific experiments can sometimes go wrong and when they do the results may range from the disastrous to the troubling. One such experiment took place in South America about fifty years ago. Whether its final consequences will cause serious damage or nothing more than a small trouble still remains to be seen. The story began in 1956 when an American scientist working in Brazil decided to solve the problem of increasing the productivity of that country's bees. He imported a very active type of African bee from Tanzania and mated it with the more easy-going native variety to produce a new kind of bees. The new bees worked harder and produced twice as much honey. It seemed that Professor Kerr, for that was the scientist's name, had a total success on his hands.www.zxxk.com Then things began to go wrong. For some reason as yet unseen, but perhaps as a result of something in their environment, the new bees began to develop extremely attacking personalities. They became bad-tempered and easy to be angry, attacked the native bees and drove them from their living places. But worse was to follow. Having taken over the countryside, the new bees, with their dangerous stings , began to attack its neighbors -- cats, dogs, horses, chickens and finally man himself. A long period of terror began that has so far killed a great number of animals and about 150 human beings. This would have been bad enough if the bees had stayed in Brazil. But now they are on the move, heading northwards in countless millions towards Central and North America, and moving at the alarming speed of 200 miles a year. The countries that lie in their path are naturally worried because it looks as if nothing can be done to stop them. The results of the South American experiment _ . | [

"It has such power over me," he admits, "but this is something I don't want to continue doing."

mmlu_train_7177 | One of the strangest races in history is about to begin. The judge raises the starting gun and says,"On your marks, get set...'' BANG! Who will win this 40-yard race? Will it be the ostrich with its long legs? Or will it be the highly trained football player? Could the squirrel rush past them all? Don't worry. It's not a real race. Last week, Scientific American magazine asked professor Peter Weyand who would win an imaginary race between an ostrich, a football player, a pig, a squirrel, and an elephant. Weyand teaches physiology. He studies the way animals move. According to his knowledge of how animals _ , here's how the race might go: The ostrich runs out of the starting gate neck and neck with the football player in second, the gray squirrel running third, and the pretty pink pig in fourth. Forty yards later, at the finish line, the heavily feathered bird beats the speeding human! The competition isn't terribly close between the ostrich and the football player, but in a surprise move, the pig moves fast and manages to beat the squirrel by a nose. Pigs don't look like they're built for speed, so its third-place finish is a bit of a shock. How does Weyand explain the Animal Kingdom's speedy match? "The easiest way to explain why the ostrich is fast is that it has long legs,'' he says. Most of the ostrich's leg muscles are high up on its short thighbones. Its long, light legs allow the bird to go faster and keep speed easily. When running, an ostrich's highest speed is about 35 mph. Elephants and squirrels actually run at the same pace. But because squirrels can accelerate quickly, the huge elephant would lose. Pigs can't speed up as fast as squirrels, but they can run faster. Pigs that live in the wild can run close to 16 mph, and squirrels can run at about 14 mph. From what Weyand explained, we can infer _ . | [

mmlu_train_8077 | A latest national survey has found that over half of China's netizens are suffering from various mental problems although some 62 percent of them claim at the same time that they are happy on the whole anyway. This is the result of China's first White Paper on Netizens' Health Conditions issued on Wednesday by 39.net, China's largest authoritative website on health sciences. It is the first most comprehensive health survey on netizens' health situation ever conducted in China in ten years' time. The white paper came out after two months of online and offline research that involved over 150 thousand netizens, covering topics and questions on health knowledge, mental situation, sense of health, and living habits. According to the white paper, more than 70 percent of China's netizens say they are suffering from mental problems such as bad memory, anxiety, depression, and a lack of confidence. And a similar 72 percent of them also say they are often suffering from diseases like insomnia, dizziness, joint degeneration and achings. Meanwhile, another 53 percent of netizens believe that white collar employees who have bigger work pressures are more likely to catch mental problems. The white paper adds, doing almost no sports and spending long time surfing online lead to the above mentioned health problems among netizens. Only 9 percent of netizens take up sports on weekends while over 40 percent stay home, surfing. And only 16 percent netizens can assure more than eight hours' sleeping daily.

mmlu_train_7334 | People who averaged fewer than seven hours of sleep per night in the weeks before being exposed to the cold virus were nearly three times as likely to get sick as those who averaged eight hours or more, a new study found. Researchers used frequent telephone interviews to track the sleep habits of more than 150 men and women aged 21 to 55 over the last few weeks. Then they exposed the _ to the virus, quarantined them for five days and kept track of who got sick. Besides sleeping more, sleeping better also seemed to help the body fight illness: Patients who fared better on a measure known as "sleep efficiency"--the percentage of time in bed that you're actually sleeping--were also less likely to get sick. The results held true even after researchers adjusted for elements such as body-mass index, age, sex, smoking and pre-existing antibodies to the virus. The researchers aren't exactly sure why sleeping better makes you less likely to develop a cold. But they do try to give an answer: "Sleep disturbance influences the regulation of symptom mediators that are released in response to infection." In plain English, maybe tossing and turning when you're infected with the cold virus contributes to the symptoms that define a cold. The researchers were based at Carnegie Mellon, the University of Pittsburgh and the University of Virginia, and the study was funded by the National Institutes of Health.

Nectarproducing plants will attract butterflies to your garden.In order to support a full butterfly life cycle,host plants (for laying eggs and used as a caterpillar food source) must also be present. Throughout the country,the general requirements for butterfly gardening are the same:full sun,nectar source plants,larval host plants,a pesticidefree environment,and knowledge of the local butterfly species.Many butterflyattracting plants are natives and require little attention,as they are naturally adapted to the region in which they live. Butterfly gardens are best planted in spring with younger plants or in fall with mature plants that will become dormant quickly and reemerge in spring.It is best not to plant in the heat of summer or the cold of winter. One of the most common mistakes in butterfly gardening is planting only one nectar source.Adult butterflies have a very short lifespan.Planting a variety of nectar sources will encourage more butterflies to visit the garden.Planting an adequate supply of host plants gives butterflies a place to lay their eggs,which will successfully hatch and result in butterflies that will continue to visit the garden. Butterflies typically lay their eggs in late spring and hatch 3-6 days after they are laid.It takes 3-4 weeks for a caterpillar to pupate and 9-14 days to emerge as an adult.

mmlu_train_39009 | If you thought taking vitamins would reduce the risk of lung cancer, think again. Researchers who studied 77,721 people said on Friday that people who took too much vitamin E,especially smokers,had a small but higher risk of developing lung cancer. They tracked the subjects'use of multi-vitamins,vitamin C and vitamin E to see if it offered protection from lung cancer.But they found that none of the vitamins was tied to a reduced risk. "If you could find some sort of magic pill--a pill you could take once a day to decrease your risk--that would be wonderful.But unfortunately.we didn't find that in our study,"lead researcher Christopher Slatore,of the University of Washington Seattle,said. The subjects of the study were followed for four years,and 521 developed lung cancer,the majority of them smokers or former smokers,Slatore's team reported in the American Journal of Respiratory and Critical Care Medicine. Among those in the study who developed lung cancer, the researchers saw a small increased risk related with vitamin E supplements in addition to the expected connections to smoking,family history and age. This added up to a 28 percent increased risk of developing lung cancer for those taking 400 mg of vitamin E supplements daily for 10 years,the researchers said. "For people--especially smokers--I suggest that they not take vitamin E(as a supplement) unless they have a very strong reason to take it." Slatore said.

mmlu_train_48825 | The sounds you make while chewing have a significant effect on the amount of food you eat, a new study has found. The results suggest that people are likely to consume less if they can hear themselves eating. Researchers at Brigham Young University and Colorado State University have found that your TV, radio, and computer are making you fat. Not by bombarding you with food ads (though they totally are) but by blocking the sounds of your chewing. In a recent study, they found that the noise your food makes while you're eating can have a significant effect on how much food you eat. "Sound is typically labeled as the forgotten food sense," adds Ryan Elder, assistant professor of marketing at BYU's Marriott School of Management. "But if people are more focused on the sound the food makes, it could reduce consumption." "For the most part, consumers and researchers have overlooked food sound as an important sensory cue in the eating experience." said study coauthor Gina Mohr, an assistant professor of marketing at CSU. The team carried out three separate experiments to quantify the effects of "food sound salience" on quantity of food consumed during a meal. In one experiment, participants were given snacks to eat while they wore headphones playing either loud or quiet noises. The ones loud enough to mask the sound of chewing made subjects eat more -- 4 pretzels compared to 2.75 pretzels for the "quiet" group. In another of their experiments they found that just having people hear chewing sounds through an advertisement can decrease the amount they eat. Elder and Morh call this the "Crunch Effect." The main takeaway of their work should be the idea of mindfulness, they said. Being more mindful of not just the taste and physical appearance of food, but also of the sound it makes can help consumers to eat less. "When you mask the sound of consumption, like when you watch TV while eating, you take away one of those senses and it may cause you to eat more than you would normally," Elder said. "The effects may not seem huge --one less pretzel-- but over the course of a week, month, or year, it could really add up." So next time you sit down for a meal, take your headphones off and mute the TV or find a movie where there's a lot of very audible chewing. When people hear themselves eating, they can _ . | [

mmlu_train_49817 | Kenya is losing an average of 100 of its 2,000 lions each year because of growing human settlements, increasing farming, climate change and diseases, according to the Kenya Wildlife Service (KWS). "Lions have a special place in Kenyans' life," said Paul Udoto, a spokesman for the organization. "Other than being the symbol of national strength, they are among the Big Five, a main attraction for visitors to Kenya." There were 2,749 lions in Kenya in 2002 and their population dropped to 2,280 by 2004 and to about 2,000 today, according to KWS figures. "The fall of the lion population is worrying and every effort needs to be made to make sure that Kenya either protects its population of 2,000 lions at present or increases the numbers to an ecologically acceptable level," said Mr. Udoto. "There is no doubt that the numbers are in free fall. I'd be surprised if they even last as long as 20 years," said Laurence Frank, project director of Living With Lions, a Kenya-based animal protection organization. "When I first came here 30 years ago, I would always hear lions roaring across the land at night and see their tracks in the morning. Now that is very rare." "The reason is simple. As the numbers of people grow and the numbers of cows increase, they take up much of the lion's space. Alongside that there are other ways, including poisoning, to kill lions." Animal lovers are making a new strategy to save the animals. Part of the measures will include tracking lions fitted with radio collars in the Amboseli area in southern Kenya, close to the border with Tanzania. Wildlife officials in Tanzania face similar challenges in protecting their lions, but there is far less human encroachment on the animals' homeland there than in Kenya.

mmlu_train_41065 | On February 3, a Laysan albatross , a large seabird, named Wisdom, which is 62 years old, hatched a healthy chick on a Pacific island near Hawaii,. It was the sixth year in a row this bird has hatched a chick. Wisdom's species normally lives only 12 to 40 years, while she is able to hatch healthy chicks into her 60s. At breeding time, the Laysan albatross will dig out a shallow nest in the ground. The female then lays a single egg. Both she and her mate will take turns incubating the egg until it hatches. More than seven out of every 10 Laysan albatrosses' nests are on just one island -Midway Atoll. That's Wisdom's home. But her species spends most of its time in the air. In fact, biologists observe that after learning to fly, these birds may not set foot on land for the next three to five years. Albatrosses are powerful gliders , With their six-foot, nearly two-meter, wingspan, Laysan albatrosses can ride wind currents for hundreds of miles or more. Biologists now estimate that Wisdom has flown for an unusually large number of miles-between two million and three million. That is equivalent to traveling from Earth to the moon and back-four to six times! And in the months when these birds are not breeding, they stay in the air, and even sleep there. Wild albatrosses often die long before they come close to Wisdom's age. Some are eaten. Others starve, get sick or suffer life-threatening injuries from people's fishing boats. Clearly, Wisdom is special. She may have raised as many as 35 chicks in her life. What can be inferred from the text? | [

mmlu_train_16786 | In an age dominated by new media and the Internet, there are so many alternative ways of learning.Gone are the days when, if we couldn't make it into a classroom, the only real option was to pick up a book, or when audio materials consisted of bad quality cassettes or sporadic radio and TV programmes.With the appearance of broadband access to the web, we have a whole new learning domain at our fingertips.Sophisticated learning materials in the form of text or high-quality audio are now available at the touch of a button, and tests and assignments can be submitted and marked online.Questions and learning, studying away from the classroom has never seemed easier.Yet many teachers would argue that face-to-face contact between teachers and students is an essential part of the language learning experience.Enter the concept of blended learning, an approach to education which seeks to combine the best of new technology and actual human contact. Advocates of blended learning argue that an approach to study which combines the benefits of new technology with the best aspects of face-to-face (often abbreviated to F2F) teaching, will achieve better results.For example, there are some aspects of study, like practical sessions, dealing with more subjective questions, or meeting the needs of an individual student, which require face-to-face human interaction, whereas the more mechanical aspects of learning, such as answers to clear-cut questions, can be managed simply and effectively in a remote environment using new technology. Blended learning approaches have proven especially appropriate in language learning.For example, in an ELT (English Language Teaching ) environment, a simple scenario might be a classroom session where a teacher asks a group of students to use a wiki to create a text. Students then go away and compose and edit the text remotely.During the next F2F session, the teacher express his opinion about their work.

mmlu_train_62995 | The Centers for Disease Control and Prevention (CDC) recently announced trends in fruit and vegetable consumption among adults. Since 2000, the CDC has made efforts with goals of getting 75% of Americans to eat two or more servings of fruit a day and 50% of Americans to eat three or more servings of vegetables a day. Unfortunately, Americans aren't meeting these modest targets. Although a diet high in fruit and vegetables can reduce the risk of many diseases, Americans just aren't getting enough. In fact, since 2000, the amount of vegetables Americans are eating has stayed the same and the amount of fruit Americans are eating has gone down. The CDC also finds that only about a third of adults are eating their expected servings of fruit, and just over a quarter of adults are eating their expected servings of vegetables. So why aren't Americans getting their expected servings of fruit and vegetables? It turns out that Americans might be spoiled when it comes to their produce. A national survey conducted by Fruit2day reveals that nearly half of Americans leave fruit in their fridges until it rots with people in Boston among the worst and those in New York and Los Angeles among the best. Sadly, most Americans admit to leaving fruit in the fridge for more than a week. There are many reasons why Americans don't eat their fruit or vegetables, including the inconvenience of having to wash or peel it. Fruit2day offers consumers a surprising and convenient way to enjoy the goodness of fruit.

This is what she told us. Just like dogs, cats and other mammals, dolphins communicate by using sound, vision , touch and taste. Each dolphin has its own signature whistle to identify itself and to call others. Dolphins don't have the ability to smell, but their hearing and eyesight are excellent. We also asked Jane if dolphins have got their own language. She told us that they have and that dolphins started talking to each other from birth. They make different sounds, including whistles, squeaks and click. Sometimes they even sound like a heavy metal band! We then asked Jane if any interesting experiments have been done. She told us that a very interesting experiment had been done with a mother dolphin and her two-year-old baby in an aquarium. They talked to each other over the telephone! The two dolphins were in separate tanks which were connected by a special under water system. Unfortunately the biologists couldn't understand what the dolphins were talking about because they haven't been able to decode dolphin language yet.

They contain links to other Web sites. And they provide a place for people to write about their ideas and react to the ideas of others. A research company called Perscus has studied more than 300 Web logs. It says that blogs are most popular with teenage girls. They use them to let their friends know what is happening in their lives. The study also says that more than 100,000 bloggers stopped taking part in the activity after a year. However, some people develop serious blogs to present political and other ideas. For example, the Republican and Democratic parties in the southern state of Kentucky recently started their own blogs. And American companies are beginning to use blogs to advertise their products.

mmlu_train_11970 | An American spacecraft is moving closer to a dwarf planet called Ceres . The American space agency's Dawn spacecraft is set to reach the planet-like object in March. Space agency scientists will then place Dawn in an orbit around the dwarf planet. Agency scientists want to know more about ice on Ceres. The spacecraft will gather clues about whether Ceres may have once had conditions to support life as we know it. Dawn left Earth more than seven years ago on a trip to explore Ceres and another dwarf planet, called Vesta . Both dwarf planets are in the main belt of asteroids , a group of large objects, between the planets Mars and Jupiter. Marc Rayman is the chief engineer and director of the Dawn mission. Scientists call Vesta and Ceres "protoplanets ". Mr. Rayman says they were in the process of becoming full-size planets when, in his words, "their growth was terminated ." Scientists believe Ceres is made of rock, and covered with ice. The Dawn mission is based in Los Angeles, California. Scientists there send second-by-second commands to the spacecraft. They direct its every move, including telling it what pictures to take. Dawn will make a map of the dwarf planet. It will also try to discover how Ceres' surface has changed. Carol Raymond is the deputy principal investigator of the project. He says Dawn made an unexpected discovery while orbiting Vesta. "Instead of being bone dry, which we expected, there were _ on the surface of Vesta that showed significant amounts of water bound in the rocks and possibly even free water that could have flowed on the surface in the past." She says that if Earth's water came from wet worlds like Vesta and Ceres, then life could have developed there, too. If Dawn finds that the environment of Ceres could have supported life, scientists may seek to explore the dwarf planet with other scientific instruments. Dawn will gather information about Ceres until the middle of 2016. It will then continue to orbit the small planet. Which of the following about spacecraft Dawn is true? | [

When people smoke, the nicotine goes right into the blood stream and makes people feel comfortable. A smoker's body gets used to the nicotine, and if he stops smoking, he feels nervous. Many smokers try to stop smoking but because of the addiction to nicotine they feel so uncomfortable that they often find it too difficult _ . Another reason is that people simply enjoy smoking. Having a cigarette for many people means taking a break. For some people smoking becomes part of certain social rituals , for example, sending the cigarette after dinner. Many people enjoy smoking because it gives them something to do with their hands. Reaching for a cigarette, lighting it and flicking the ashes are special comfort in a situation where they feel nervous. Many people also like the taste of tar in cigarettes. However, it is the tar that causes cancer.

They were each given a basket. They picked for an hour and got several pounds. It was hard work picking the little berries from the trees. Now Billy understood why they were expensive in the store. Next, they had to wash the fruit. Some of them still had leaves. Those had to be pulled off. Then the bad berries had to be thrown away. They washed the berries and made them air-dry. After that, they pushed the blueberries through a strainer . The strainer caught most of the seeds and skins, and only left a small glass of dark purple juice to _ When they tasted the juice, it wasn't very sweet. Billy's uncle didn't want to add white sugar to the juice. It was better to use a naturally sweet juice, like apple juice, pear juice, or grape juice. They used grape juice as a sweetener , because grapes had a similar color to the blueberries. Finally, they could drink it. It was a lot of work to make juice, but it sure was refreshing! Billy's uncle hadn't made _ juice before. | [

mmlu_train_22865 | Kids at the Interlake School Division were the first Canadian students to take part in a program to send experiments to the International Space Station.(ISS). Jordan Schott and three other sixth grade students came up with the idea to test royal jelly in space . Their experiment came very close to be tested on the space station. "We were seeing if we could send it to space, and if it would lose its nutritional value" faster and or slower, "said Schott. Schott is one of the 18 students in the Space Knights Club at Woodlands Elementary School, part of the Interlake School Division. Over 450 students from the Division took part in the program. "I thought we were just students and we couldn't do much in the way of that. It's a way to communicate with people up there ," said Braeden Clark, a seventh grade student who is also in the club. The astronauts shared what they learned with their school with a full day of activities all about science and space. Teacher Maria Nickel is the organizer of the club. She said the day was great for students to learn what they could do. "Space is one of those great things that get kids excited, but it also gives them the chance to do so much. They can be an astronaut; they can be an engineer, "She said. The day was held in honour of Chris Hadfield, a Canadian astronaut now in the Internal Space Station. "It gives kids someone more to look up to. Here's a real hero to look up to who's doing it all, doing it through education," said Nickel. Jordan Schott thinks it's really cool. "To me it seems so cool how people can go up to space, and science is something I've always liked," She said. Schott says she wants to follow in the footsteps of Hadfield and be an astronaut when she gets older. One of the winning experiments in the competition was produced by students from Argyle, Manitoba. It will travel to the space station in the fall of 2013. What do we know Jordan Schott? | [

mmlu_train_27311 | It's hard to track the blue whale, which has almost been killed off by commercial whaling. Attaching radio devices to it is difficult and visual sightings are too unreliable to give real insight into its behavior. So biologists were delighted early this year when, with the help of the US Navy, they are able to track a particular blue whale for 43 days recording its sounds. This was possible because of the Navy's former top secret system of underwater listening devices across the oceans. Tracking whales is but one example of an exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies. Earth scientists announced at a news conference recently that they had used the system for closely observing a deep-sea volcanic eruption for the first time and that they planned similar studies. Other scientists have proposed to use the network for tracking ocean currents and measuring changes in the ocean and global temperatures. Different layers of ocean water can act as channels for sounds focusing them in the same way a stethoscope does when it carries faint noises from a patient's chest to a doctor's ear. This focusing is the main reason that even relatively weak sounds in the ocean, especially low-frequency ones, can often travel thousands of miles. What can we infer from the passage? | [

It's a glimpse of the future, according to famed British scientist Stephen Hawking. "I see great dangers for the human race," he said in an interview with global forum Big Think. "There have been a number of times in the past when its survival has been a question of touch and go ." Hawking says humans must _ our home planet within the next two centuries and expand into space to survive. "I believe that the long-term future of the human race must be in space," he said. "It will be difficult to avoid disaster on our planet Earth in the next hundred years, let alone the next thousand, or million." He also voiced some concerns about the future of life on the earth. In April, he spoke about his fear of aliens in an interview for the Discovery Channel. "If aliens visit us, the outcome would be much as when Columbus landed in America, which didn't turn out well for the Native Americans," he said. "Such advanced aliens would perhaps become wanderers, looking to conquer and colonize whatever planets they can reach." But Hawking says he is still hopeful for the future of humanity. "I'm an optimist," he told Big Think. "We have made remarkable progress in the last hundred years. But if we want to continue beyond the next hundred years, our future is in space." Getting to another planet will prove a challenge, not to mention colonizing it for humanity. University of Michigan astrophysicist Katherine Freese told Big Think that "the nearest star to Earth is Proxima Centauri which is 4.2 light years away. That means, if you were traveling at the speed of light the whole time, it would take 4.2 years to get there" --- or about 50,000 years using current rocket science.

mmlu_train_30165 | At 26, Jane Goodall had no college education or science training. But since childhood, she had been dreaming of working closely with animals in Africa. "All through my childhood people said you can't go to Africa. You're a girl." Goodall said. "But my mother used to say, if you really want to, there's nothing you can't do." In 1957, the 26-year-old Goodall went to Kenya to work as a secretary. She also arranged to meet the famous scientist Louis Leakey, who was so impressed by her enthusiasm that he hired her as his assistant. She went with him on many trips to the African jungle and in 1960 Leakey sent Goodall to live among chimpanzees in a remote animal preserve, recording the animals' behavior and interactions. For three months Goodall made little progress. But she said, "I never came close to giving up." Her breakthrough came one day when she saw a male chimpanzee stick a piece of grass into a termite hill, then put the grass in his mouth. Afterward she came to the hill and did the same. Pulling the grass out, she discovered dozens of termites on it. The discovery -- that some animals use tools -- was unknown to most scientists at the time. Goodall saw chimpanzees exhibit human-like emotions, such as jealousy and love. But she also discovered they were capable of violent attacks against each other. Goodall received her Ph.D. in the study of animal behavior at England's Cambridge University. Now she travels around the globe raising money to preserve wildlife.

mmlu_train_48109 | When you buy cooking oil in the supermarket, you may notice that some brands are labeled as "GM (genetically modified)-free". So, what is genetic modification? Are GM foods safe? These questions have been put back into the spotlight recently. On Nov 19, the Food and Drug Administrati0n (FDA) in the US announced that it had approved the AquAdvantage salmon to go on the market, making it the first genetically modified animal to be approved as food anywhere in the world. GM foods are plants or animals that have been given a gene from another plant or animal to make them stronger in some way. The AquAdvantage salmon contains a gene from another type of salmon that makes it grow faster. Although the FDA has said "food from the fish is safe to eat", some believe that scientists can't completely understand the potential health risks of GM foods, simply because they're so new. Others worry that the fish could escape into the wild and cause ecological problems. GM crops have experienced the same controversy, even though GM technology cuts down on the use of pesticides on crops and increases yields. While GM animals are new, GM crops have already appeared on our plates: A total of 28 countries in the world including the US, Brazil and India planted 181.5 million hectares (1.815 million km2) of GM crops in 2014, according to the International Service for tile Acquisition of Agri-biotech Applications. In China, we grow GM cotton and papaya and import GM soybeans, corn, rape, cotton and beets from abroad. Due to safety worries, many countries have regulations for producing and selling GM food. In European Union countries, each GM food must be approved before it can be used. This process can take up to 17 months. The origin of all GM foods must also be traceable, and all food with a GM content of more than 0.9 percent must also be labeled, according to EU website europa.eu. The US is less strict about GM foods. According to FDA regulations, companies introducing new GM foods to the market should report them at least 120 days before release. The labeling is voluntary, except that a product cannot be labeled as "GM-free" if genetically modified materials are used. In China, GM foods can only be produced after strict tests by the Ministry of Agriculture say that they are safe. All food that is made from GM crops or contains GM ingredients must be clearly labeled on the wrapper. From-the text, it can be concluded that GM crops _ . | [

mmlu_train_25965 | People around the world drink about 180 billion liters of soda a year. That translates to more than 29 liters per person. Experts say the amount of carbonated soft drinks we consume is growing. New research from the American Heart Association finds that drinking soda, even diet soda, may significantly increase your risk for heart disease. Dr. Ramachandran Vasan led the study. "Drinking just one or more sodas a day may not be as innocuous as people think." In a large study of 9,000 people, doctors discovered that those who drank one or more sodas a day had a 30% increased risk for obesity , a 25% increase in the risk for abnormal blood sugar levels, and a 32% increase in the odds of having low levels of good cholesterol . All of these factors increase the risk for heart disease. And there was no difference in the results for those who drank diet soda over regular soda. It's something that surprised even the researchers. Critics of the study say diet soda may not be the cause of increased risk of heart disease. Connie Diekman is president of the American Dietetic Association. "It does not conclusively say that this will cause that." In other words, it could be that unhealthy people like soda. Dr. Vasan found those who drink soda generally tend to have greater caloric intake. They eat more saturated fat and trans fats. They also eat less fiber and exercise less. Diet soda drinkers may also share this unhealthy lifestyle. Dr. Vasan agrees that the link he found between heart disease risk and diet soda needs additional study.

mmlu_train_50797 | Back in the 1860s, a British scientist named Henry Walter Bates noticed something interesting in the animal world: a kind of butterfly, Common Mormon, can change the pattern on its wings so that it looks like another butterfly species, the Common Rose, which is poisonous for birds to eat. Bates argued that animals develop this ability to protect themselves from being eaten. This theory had been widely accepted by scientists. But one question remains: how do these animals manage to do that? After more than 150 years, scientists are finally able to answer that question--it is all down to a gene called "doublesex", according to a study published on March 6 in the journalNature. In fact, scientists have long known that genes are responsible for this useful ability. But until the new study, scientists hadn't been able to find out which genes in particular were responsible. Scientists at the University of Chicago compared the genetic structures of the Common Mormons that changed their wing patterns with those of ones that did not. And all the results pointed to a single gene, "doublesex". This was much to the scientists' surprise. They used to expect that something as complex as this would be controlled by many different genes. For example, one gene would control the color of the upper part of the wing, one would do so for the lower part. However, the "doublesex" gene doesn't quite do everything by itself. Instead, it acts like a switch--it "tells" other genes to change the wing patterns. Isn't that clever? Scientists believe that this special ability of the "doublesex" gene on Common Mormon was developed throughout the long history of evolution. "The harmless species gains an advantage by resembling something predators avoid," Sean Carroll, a scientist toldNature. "it was obvious evidence for natural selection. " How do scientists find the truth of butterfly changing wing patterns? | [

mmlu_train_53208 | Carbon monoxide poisoning kills and injures many people and animals around the world. The gas has been a problem since people first began burning fuels to cook food or to create heat. It is a problem in all parts of the world that experience cold weather. Carbon monoxide is called the silent killer because people do not know it is in the air. The gas has no color1. It has no taste. It has no smell. It does not cause burning eyes. And it does not cause people to cough. But it is very deadly. It robs the body of its ability to use oxygen. Carbon monoxide decreases the ability of the blood to carry oxygen to body tissues. It does this by linking with the blood. When the gas links with the blood, the blood is no longer able to carry oxygen to the tissues that need it. Damage to the body can begin very quickly from large amounts of carbon monoxide. How quickly this happens depends on the length of time a person is breathing the gas and the amount of the gas he or she breathes in. Carbon monoxide poisoning has warning signs. But people have to be awake to recognize them. Small amounts of the gas will cause a person's head to hurt. He or she may begin to feel tired. The person may feel sick. The room may appear to be turning around. The person may have trouble thinking clearly. People develop severe head pain as the amount of gas continues to enter their blood. They will begin to feel very tired and sleepy. They may have terrible stomach pains. Medical experts say carbon monoxide affects people differently. For example, a small child will experience health problems or die much quicker than an adult will. The general health of the person or his or her age can also be important. An older adult with health problems may suffer the effects of carbon monoxide more quickly than a younger person with no health problems. People with heart disease may suffer chest pains. They may begin to have trouble breathing. Why is carbon monoxide called the silent killer? | [
