mmlu_train_66867 | Mr King was the manager of a hotel. One weekend all the hotels in the city were full because there was a large meeting. On Friday night, three men came into the hotel and asked for rooms. Mr King said there were no rooms ready because of the meeting. The men were unhappy. Mr King wanted to help them. He remembered that Room 418, a very small room, was empty. He asked them if they would share a room. The three men said they would. Mr King said the room would be thirty dollars: ten for each one. Each man gave him the money and then went up to the room. Mr King soon began to feel sorry. "Thirty dollars is a lot to ask as price for that small room. " he thought. He called his assistant over and said, "Here is five dollars. Take it to the men in Room 418. I asked too much for their room." The assistant took the money. While he was on the way there, he started to think, "How can three men divide five dollars? I'll give them each only one dollar and keep the two dollars for myself. The men will be happy to get something back, and Mr King will never know. " So the assistant returned one dollar to each man. Each man had at first paid ten dollars. After the assistant returned them one dollar each, each had paid nine. There were three men, $ 9 x3 = $ 27. The assistant kept $ 2. $ 27 + $ 2 = $ 29. Where is the missing dollar?

mmlu_train_6356 | Solar water heaters can use energy from the sun to heat water. They are used around the world. The solar water heater is based on a design developed some years ago in Afghanistan. Since then, it has been built and used in many countries. It can heat seventy liters of water to 60degC. It can do this between sunrise and noon on a clear day with an average temperature of 32degC. There are two parts of the solar water heater. One part, the collector, is made of a metal plate painted black. This metal surface, placed in contact with the water, will heat the water. Black-painted surfaces that receive the sun's heat become hotter than those of any other color1. Metal plates that have raised parts on the surface work better than those without them. Once the water is heated, it is kept hot with special material, which allows the water to stay warm for a long time. The second part of the solar water heater holds the water for the system. This water tank can hold about one hundred liters of water. Two rubber pipes are connected to the water tank. One pipe lets water go into the system. The other lets water go out. When the water heater is working correctly, water will flow from the tank to the collector and back again. You can use the hot water at the top of the tank for washing and cleaning. This solar water heater is easy to build and operate. It will last about two years before the rubber pipes need to be replaced. We can learn that solar water heaters _ . | [

mmlu_train_36982 | A recent survey by the Royal College of Nursing (RCN) found that about a third of nurses inprefix = st1 /UKplanned to give up their jobs in the next two years because of the amount of worries and unhappiness with their pay. Among those under 40, the percentage of nurses planning to leave their employers increased from 32% in 2005 to 36% in 2007. The survey also found that 71% of nurses believed they could be paid more for less effort if they left nursing, compared to 60% in 1997. The research was published as the RCN hosted a meeting for nurse leaders to deal with the growing concerns of the nurses. Josie Irwin, an RCN expert, said, " Many nurses say that changes in junior doctors' hours have resulted in an increase in their workload. Nurses are under more and more pressure." Ms Irwin added, "Only 22% of all nurses disagree that they are under too much pressure." She also said that 27% of nurses had a second job, with the main reason that they needed some extra income. "Nurses have made it clear that while they enjoy their work, they have more to do than ever and are not being paid enough to do it." She added. " For this reason, the RCN is calling for a pay increase for nurses to bring their pay into line with others." The survey of 4,795 nurses found that some important changes to the profession had taken place in recent years. The average age of the nurses questioned was 42 ---compared to an average of 33 in 1987. The RCN said that the age increase was because people were now becoming nurses later.

mmlu_train_52296 | You may have seen a lot of frogs, but if you haven't, you must have heard about frogs. However, have you heard about a frog that can kill a person? These small brightly colored amphibians live in the tropical rain forests of Central and South America. They are best known for their ability to kill persons even though they are no more than 2 inches long. If we touch their poisonous skin without proper protection (such as gloves), we may die! For animals of this size that can be so deadly, they are certainly one of the world's most poisonous animals! Who are they? They are poison arrow frogs or, simply, poison frogs. Poison frogs acquired their name from the Indians. The Indians catch and kill many of these frogs before hanging them upside down over a campfire. As the frogs get hot, the poison drips out of their skin. The Indians collect the poisonous liquid in a bottle and dip the tips of their arrows into the bottle. Once the tips are dried, they are ready to be used for their arrows for hunting. There are about 170 different types of poison arrow frogs in the world. Though most species have bright markings, either in stripes or patches, on their black bodies, some just wear noticeable single-colored coats. Their shocking skin colors-usually in yellow, red, green, blue or orange-serve as a warning sign to other animals. The sign simply says," Stay away or pay with your life!" They certainly do not bluff. Which of the following best explains the last sentence of the passage? | [

It will be a few months before we have good medicine for bird flu.But that doesn't mean you can't do anything to prevent it now. So far, all the people who have caught bird flu have been those who touched sick chickens or their droppings . So it is a good idea for people to stay away from live chickens. "People used to go to the markets to buy live chickens to eat, but now they have to change that habit," said Peter, an expert from World Health Organization. But if you do touch a sick bird, remember to wash your hands carefully with soap right away. Experts also say having good habits and a healthy body will help keep you safe from bird flu. For example, don't buy or eat birds that have not been checked. Don't eat anything that has touched raw meat. Also don't forget to open your windows often and exercise regularly. Getting enough sleep is also very important for fighting illness .If you feel sick, see a doctor right away.At present, no one in Shanghai has bird flu.

mmlu_train_48208 | Houseplants clean the air and brighten a room. Occasionally, they drive us mad as we wonder how exactly we managed to kill yet another "unkillable" houseplant. (In that way, they provide great lessons in perseverance as well!) But it looks like there's one more great reason to grow houseplants: their presence in your workspace might actually make you smarter. According to a recent study published in The Journal of Environmental Psychology, just having plants in your work space is enough to increase your attention span. An increase in attention span means that we're able to remember more of what we read. To test the hypotheses, the study's authors gave subjects a Reading Span Task, which requires reading sentences aloud, then remembering the last word in each sentence. This requires reading, memorization, and recall abilities, and switching between the three. The researchers had their entire test pool complete Reading Span Tasks to get a baseline reading. Then they moved some of the people to a room with no plants, and others to a room that had four plants around the desk. They were all asked to repeat the Reading Span Tasks, and the people who worked near a plant improved overall, while those without plants stayed roughly the same. Beauty, fresh air, the joy of caring for another living thing -- all great reasons to have a few houseplants around. If they help increase attention spans, all the better!

mmlu_train_53141 | ScienceDaily (July 5, 2009) -- Researchers from the University of Haifa-Oranim have managed to make out the "self-irrigating" mechanism of the desert rhubarb , which enables it to harvest 16 times the amount of water collected by other plants in the Negev Desert. This is the first example of a self-irrigating plant worldwide. The desert rhubarb grows in the mountains of Israel's Negev desert, where average rainfall is particularly low (75 mm per year). Unlike most of the other desert plant species, which have small leaves so as to reduce water loss, this plant is unique in that its leaves are particularly large; each plant's rosette of one to four leaves reaches a total diameter of up to one meter. Prof. Simcha Lev-Yadun, Prof. Gidi Ne'eman and Prof. Gadi Katzir came across this unique plant while studying the field area with students of the Department of Science Education-Biology of the University of Haifa-Oranim, and noticed that its waxy leaves are unusually large. They observed an exceptionally ridged structure on each leaf. The scientists explained that these deep and wide depressions in the leaves create a "channeling" mountain-like system by which the rain water is channeled toward the ground surrounding the plant's deep root. Other desert plants simply absorb the rain water that goes through the ground in its immediate surroundings. The desert rhubarb is able to harvest quantities of water that are 16 times the amount of water harvested by the small-leafed plants of the Negev desert region. When the research team watered the plant artificially, they observed how the water flows along the course of the leave's depressions to the ground surrounding the plant's single root and then goes through the ground to a depth of 10 cm or more. Under the experimental conditions, water goes through the ground only as deep as 1 cm. "We know of no other plant in the deserts of the world that functions in this manner," the researchers concluded. What is the best title for the passage? | [

mmlu_train_6109 | Burning less calories while walking seems like a bad idea, but making the walk easier may actually keep people on their feet longer, and that scientists say, has substantial health benefits. Analyzing the human walk, biomedical engineers Steven Collins and Greg Sawicki concluded that our ankles and calves perform motions similar to a spring coupled with a clutch that intermittently stores and releases energy. Sawicki, from the University of North Carolina, explained what's involved. "We found in basic science experiments that that system, your calf and Achilles tendon, works a lot like a catapult. So, the muscle holds on to the tendon and your body actually stretches your Achilles tendon quite a bit and then stores the energy in the tissue and then it's given back to _ you forward in the world," he said. Sawicki said he and his colleague Steven Collins at Carnegie Mellon University designed a mechanical device, made of carbon fiber and metal, that performs the same sequence of energy give-and-take outside the body. The system takes over part of the work of walking, and reduces the amount of required energy by as much as seven percent. Wearing the unpowered ankle exoskeleton can help people either walk farther with the same amount of energy, or restore the normal movement pattern for people who have trouble walking. Sawicki said it takes only a few minutes to get used to the exoskeleton but the wearer quickly learns to tone down the muscle energy as the device takes over part of the load. "You really don't notice it until when you take it off. And when you take it off you realize that it was there and giving you the boost," he said. Sawicki added that the device is primarily intended for people recovering from surgery or a stroke. But all persons who spend a lot of time walking, such as police officers or hospital personnel, could benefit from it. At the moment there are no plans to develop the ankle exoskeleton for the market, but the inventors say some manufacturers have expressed interest. What's the main idea of the passage? | [

mmlu_train_66146 | Cell phones: is there a cancer link? Could your cell phone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, power lines and Wi-Fi could be responsible for a range of illnesses, from rashes to brain tumors. Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks there's a greater than 95 percent chance that power lines can cause childhood leukemia . Also there's a greater than 90 percent chance that cell phones can cause brain tumors. "It's apparent now that there's a real risk, " said Carpenter. But others believe these concerns are unjustified. Dr Martha Linet, the head of radiation epidemiology at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. "I don't support warning labels for cell phones, " said Linet. "We don't have the evidence that there's much danger. " Studies so far suggest a weak connection between EMFs and illness-- so weak that it might not exist at all. A multinational investigation of cell phones and brain cancer, in 13 countries outside the US, has been underway for several years. It's funded in part by the European Union, in part by a cell phone industry group. The final report should come out later this year, but data so far don't suggest a strong link between cell phone use and cancer risk. From the passage we can learn that some people are worried because _ . | [

mmlu_train_54905 | An out-of-body experience? It's just your brain playing tricks on you. Some report feeling as if they are floating above their own bodies, while others find themselves drawn towards a blinding light. But out-of-body experiences are nothing more than a trick of the mind, scientists claim. They say that common spooky scenarios, such as floating above a hospital bed or walking towards the light at the end of a tunnel, can be explained by the brain trying to make sense of the process of death. Scientists from the universities of Edinburgh and Cambridge reviewed studies into changes in the brain that cause certain strong feelings associated with near-death experiences. Researcher Caroline Watt said one common vision -- that of people seeing a bright light which seems to be drawing them into the afterlife -- is probably produced by the death of the cells we use to process the light picked up by our eyes and turn it into pictures. "It is simply your brain trying to make sense of the unusual experiences you are having," Dr Watt said. Feelings of being out of the body can also be explained by the brain's behavior, the journal Trends in Cognitive Science reports. "If you put on a virtual reality headset showing an image of yourself three feet in front, you can trick your brain into thinking that is you over there, and get the sense you are outside your body," Dr Watt added. The scientific evidence suggests that all aspects of the near-death experience have a biological basis. In another example, the hormone noradrenalin, which is released when we suffer from stress and injuries, could be behind the feelings of love and peace that many experience when they seem to be approaching death. However, other scientists say we should not be so quick to dismiss (stop considering) people's accounts (descriptions). Sam Parnia, of the University of Southampton, stressed that being able to trace something back to the brain does not mean it is not real. Dr Parnia, who is close to completing a three-year study of hospital patients' recollections of their near-death experiences, said, "Every experience, whether near-death or otherwise -- such as depression, happiness and love -- is mediated by the brain." According to the passage, when people are dying, some may have the following feelings except that _ . | [

mmlu_train_38149 | Over a period of time, many habitats change with respect to the types of plants and animals that live there. This change is known as succession. Succession occurs because plants and animals cause a change in the environment in which they live. The first weeds and grasses that appear on a bare field, for example, change the environment by shielding the soil from direct sunlight. As these plants spread, the ground becomes cooler and more moist than it was originally. Thus, the environment at the ground surface has been changed. The new surface conditions favor the sprouting of shrubs. As shrubs grow, they kill the grasses by preventing light from reaching them and also enhance the soil. Pine seedlings soon take hold and as they grow, they in turn shade out the shrubs. They are not able to shade out oak and hickory seedlings, however, that have found the forest floor suitable. These seedlings grew into large trees that eventually shade out the pines. Which of the following is a stage of succession as described in the passage? | [

mmlu_train_25908 | That "Monday morning feeling" could be a crushing pain in the chest which leaves you sweating and gasping for breath. Recent research from Germany and Italy shows that heart attacks are more common on Monday mornings and doctors blame the stress of returning to work after the weekend break. The risk of having a heart attack on any given day should be one in seven, but a six-year study helped by researchers at the Free University of Berlin of more than 2,600 Germans showed that the average person had a 20 per cent higher chance of having a heart attack on a Monday than on any other day. Working Germans are particularly not protected against attack, with a 33 per cent higher risk at the beginning of the working week. Non-workers, by comparison, appear to be no more at risk on a Monday than any other day. A study of 11,000 Italians proved 8 am on a Monday morning as the most stressful time for the heart, and both studies showed that Sunday is the least stressful day, with fewer heart attacks in both countries. The findings could lead to a better understanding of what is the immediate cause of heart attacks, according to Dr Stefan Willich of the Free University. "We know a lot about long-term risk factors such as smoking and cholesterol but we don't know what actually causes heart attacks, so we can't give clear advice on how to prevent them," he said. Monday mornings have a double helping of stress for the working body as it makes a rapid change from sleep to activity, and from the relaxing weekend to the pressures of work. "When people get up, their blood pressure and heart rate go up and there are hormonal changes in their bodies," Willich explained. "All these things can have an unfavourable effect in the blood system and increase the risk of a clot in the arteries which will cause a heart attack." "When people return to work after a weekend off, the pace of their life changes. They have a higher workload, more stress, more anger and more physical activity," said Willich.

mmlu_train_45177 | Our risk of cancer rises rapidly as we age. So it makes sense that the elderly should be routinely screened for new tumors or doesn't it? While such tracking of cancer is a good thing in general, researchers are increasingly questioning whether all of this testing is necessary for the elderly. With the percentage of people over age 65 expected to nearly double by 2050, it s important to weigh the health benefits of screening against the risks and costs of routine testing. In many cases, screening can lead to additional examinations and operations to remove cancer, which can cause side effects, while the cancers themselves may be slow-growing and may not cause serious health problems in patients' remaining years. But the message that everyone must screen for cancer has become so ingrained that when health care experts recommended that women under 50 and over 74 stop screening for breast cancer, it caused a noisy reaction among doctors, patients and social groups. It's hard to uproot deeply-held beliefs about cancer screening with scientific data. Certainly, there are people over age 75 who have had cancers detected by routine screening, and gained several extra years of life because of treatment. And clearly, people over age 75 who have other risk factors for cancer, such as a family history or previous personal experience with the disease, should continue to get screened regularly. But for the rest, the risk of cancer, while increased at the end of life, must be balanced with other factors like remaining life expectancy. A recent study suggests that doctors start to make more objective decisions about who will truly benefit from screening--especially considering the explosion of the elderly. It's not an easy calculation to make, but one that makes sense for patients. Dr. Otis Brawley said, "Many doctors are ordering these tests purely to cover themselves from medical disputes. We need to think about the wise use of health care, which means making some difficult decisions with elderly patients, and going against the misguided belief that when it comes to health care, more is always better."

What we tend to forget is that this goes for our eyes as well. Medical science confirms that a diet rich in carotenoids can help maintain good vision and prevent against a number of eye diseases. Here's some advice about how to choose the right diet to keep your eyes healthy. -- Eat orange food. Fruits and vegetables with orange flesh are rich in carotenoids. In addition to carrots,oranges,pumpkins and sweet potatoes are also available. All of these contain high levels of carotenoids,which help to maintain good vision. -- Include dark green vegetables,such as spinach and broccoli in your diet, to act as natural sunglasses. Recent scientific studies have shown that these vegetables can help block the damaging UV radiation from the sun's rays. -- Prevent some eye diseases with orange juice, yellow corn, whole milk, nuts and leafy vegetables. These foods are good sources of vitamins A, C, D and E. All of these are necessary to good eye health. -- Increase your intake of omega!3 with some sea fish, and some other seafood. Omega-3 helps build cell walls and is especially beneficial to keeping eyes healthy .It also helps regulate the eye's internal pressure and helps the eye dry up excess fluid.

mmlu_train_30263 | Working with a group of baboons in the Namibian desert, Dr. Alecia Carter of the Department of Zoology,Cambridge University set baboons learning tasks involving a novel food and a familiar food hidden in a box. Some baboons were given the chance to watch another baboon who already knew how to solve the task, while others had to learn for themselves. To work out how brave or anxious the baboons were, Dr. Carter presented them either with a novel food or a threat in the form of a model of a poisonous snake. She found that personality had a major impact on learning. The braver baboons learnt, but the shy ones did not learn the task although they watched the baboon perform the task of finding the novel food just as long as the brave ones did. In effect, despite being made aware of what to do, they were still too shy to do what the experienced baboon did. The same held true for anxious baboons compared with calm ones. The anxious individuals learnt the task by observing others while those who were relaxed did not, even though they spent more time watching. This _ between collecting social information and using it shows that personality plays a key role in social learning in animals, something that has previously been ignored in studies on how animals learn to do things. The findings are significant because they suggest that animals may perform poorly in cognitive ( )tasks not because they aren't clever enough to solve them,but because they are too shy or nervous to use the social information. The findings may impact how we understand the formation of culture in societies through social learning. If some individuals are unable to get information from others because they don't associate with the knowledgeable individuals,or they are too shy to use the information once they have it,information may not travel between all group members, preventing the formation of a culture based on social learning.

The survey shows 91% think the Net helps their children explore their passions, and 77% think the Internet is one of the most valuable education tools teens have. But 88% think it's important to know what their kids are doing online. Findings suggest both parents and teens need more education about using online media, Steyer says.

mmlu_train_40640 | Everybody needs blood Have you ever seen buses on the street for donating blood? Medical workers on board collect blood from volunteers. The blood is then stored up and given to people who have lost a large amount of it due to accidents or diseases. Blood is one of the most important substances supporting our lives. But for now, the only way we can get more of it is through donation. And donated blood has its own problems. First of all, certain blood types are extremely rare. Type O negative blood (O-), for example, only exists in 7 percent of people, according to Sunday Times. There are fewer donors and therefore there isn't enough of this type of blood for everybody who needs it. In addition, donated blood comes from various people, which means that it has to be examined carefully for disease such as hepatitis and HIV to make sure that it's safe for transfusion. This is why scientists all over the world have been trying to make blood in labs. And now, someone finally succeeded--Marc Turner at the Scottish National BloodTransfusion Service has produced blood fit for transfusion, reported Forbes. Unlike many other scientists, who have tried to make blood substitutes by mixing up different ingredients together, Turner chose to grow blood directly from human stem cells . He developed a special technique to create a chemical environment similar to that in our bone marrow . This environment encourages stem cells to develop fully into red blood cell. According to Turner, his version of artificial blood is unlikely to contain disease viruses or produce side effects. And the best part is that what he managed to produce was type O- blood. Not only is it a rare blood type, it's also a universal type, which means it can be transfused into any patient. The new blood is scheduled for human tests in 2016. However, Turner stressed that the new study should not be taken as a signal for people to stop donating blood because it could be another 20 years before the artificial blood can be manufactured on a large scale. "It is one thing to bake a cake and another thing to bake a cake 100 times the size," said Turner. "It's not just a matter of putting in 100 times the ingredients."

I was lucky: I became a pilot in 1970, almost ten years before I graduated from medical school. I didn't realize then, but becoming a pilot makes me a better surgeon. I loved flying. As I flew bigger, faster planes, and in worse weather. I learned about crew resource management , or CRM, a new idea to make flying safer. It means that crew members should listen and speak up for a good result, regardless of positions. I first read about CRM in 1980. Not long after that, an attending doctor and I were flying in bad weather. The controller had us turn too late to get our landing ready. The attending doctor was flying; I was safety pilot He was so busy because of the bad turn, he had forgotten to put the landing gear down. He was a better pilot - and my boss - so it felt unusual to speak up. But I had to: Our lives were in danger. I put aside my uneasiness and said, "We need to put the landing gear down now!" That was my first real lesson in the power of CRM, and I've used it in the operating room ever since. CRM requires that the pilot/ surgeon encourage others to speak up. It further requires that when opinions are from the opposite, the doctor doesn't overreact, which might prevent fellow doctors from voicing opinions again. So when I'm in the operating room, I ask for ideas and help from others. Sometimes they're not willing to speak up. But I hope that if I continue to encourage them, someday someone will keep me from " _ ". What does the author say about doctors in general? | [

mmlu_train_55482 | Every human being has a unique arrangement of the skin on his fingers and this arrangement is unchangeable. Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case. The ridge structure on a person's fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one which bears a reproduction of the original pattern. It is only when the inner skin is injured that the arrangement will be destroyed. Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take. Finger-prints can be made very easily with printer's ink. They can be recorded easily. With special methods, identification can be achieved successfully within a short time. Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. His finger-prints can prove who he is even if his appearance has been changed by age or accident. When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye. Special techniques are used to "develop" them. Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.

mmlu_train_66376 | NOT all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences in nightmares. Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly wipe out, the effect of painful memories. In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are wiped out. They are not sure to what degree people's memories are affected. The research has caused a great deal of argument. Some think it is a bad idea, while others support it. Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war. They say that there are many people who suffer from terrible memories. "Some memories can ruin people's lives. They come back to you when you don't want to have them in a daydream or nightmare. They usually come with very painful emotions," said Roger Pitman, a professor of psychiatry at Harvard Medical School. "This could relieve a lot of that suffering." But those who are against the research say that maybe the pills can change people's memories and changing memories is very dangerous because memories give us our identity. They also help us all avoid the mistakes of the past. "All of us can think of bad events in our lives that were terrible at the time but make us who we are. I'm not sure we want to wipe those memories out, "said Rebecca Dresser, a medical ethicist. We can infer from the passage that _ . | [

mmlu_train_9232 | Scientists around the world have been studying the warming of waters in the Pacific Ocean known as El Nino . The appearance of El Nino is known to affect the weather around the world. Scientists still do not completely understand it. Yet they now find they can use it to tell about the future in different areas of the world. One example is the work of two scientists at Columbia University in New York, Mark Cane and Gordon Eshel. A scientist of Zimbabwe , Roger Buckland worked with them. They have found that when El Nino appears, Zimbabwe has little or no rain. This means corn crops in Zimbabwe are poor. The last El Nino was in 1991 to 1993. That was when southeastern Africa suffered a serious lack of rain. The scientists wrote about their recent work in the publication Nature. Their computer program can tell when an El Nino will develop up to a year before it does. They suggest that this could provide an effective early warning system for southern Africa, and could prevent many people from starving. What's the best title for this passage? | [

mmlu_train_90002 | When kids at Archisha Singh's school in Loudoun County have a birthday, no parents buy them birthday cakes. Some schools are worried that children might become fat or eat unhealthy food, so they have banned cupcakes altogether. What do kids do? Birthday kids can donate a book. The headmaster of their school will then read it to their class. The headmaster also hands out birthday certificates , special pencils, and makes sure the kids' names are read out in the school's morning news. Parents can send stickers , pencils and other things to students. None of the things can be food. If a child donates jump ropes or other sports equipment, that child may get his or her name on a certificate. It will then be displayed at school. Archisha really misses cupcakes, especially those her mother used to make for her kindergarten class, but her school's way is fun, too. "I like both ways," she said. The headmaster says it's important that the school should be not only teaching, but offering healthy choices to kids. "There is a better life without cupcakes. If you eat a cupcake, then it's gone in two seconds, but a book lasts a lifetime. The sports equipment lasts, and the kids can use it day after day." What do birthday kids do? | [

mmlu_train_67563 | Since the 1970s, scientists have been searching for ways to connect the brain with computers. Braincomputer interface(BCI) technology could help people with disabilities send commands to machines. Recently, two scientists, Jose Millan and Michele Tavella from the Federal Polytehnic School in Lausanne, Switzerland, show a small robotic wheelchair directed by a person's thoughts. In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts. "Our brain has billions of body cells . These send signals through the spinal cord to the body part to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the body part." Tavella says. "Our system allows disabled people to communicate with outer world and also to control machines." The scientists designed a special cap for the user. This head cover picks up the signals from the scalp and sends them to a computer. The computer finds meanings of the signals and commands the wheelchair with an engine. The wheelchair also has two cameras that tell objects in its path. They help the computer react to commands from the brain. Prof. Millan , the team leader, says scientists keep improving the computer software that finds meanings of brain signals and turns them into simple commands." The practical possibilities that BCI technology offers to disabled people can be grouped in two kinds: communication, and controlling objects. One example is this wheelchair." He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can get advantages from. And the other is sure that they can use the technology for long. BCI is a technology that can _ . | [

mmlu_train_9375 | When English as a foreign language is taught to children at the primary and early secondary levels of education, it is generally taught with a general education aim in mind--that is, it is regarded as a "good thing" for them to learn a foreign language as a part of a broad education. There is usually, however, no immediate and specific requirement for such children to make use of the language in any communicative situation. The purpose of learning the language is essentially a "deferred" purpose, deferred till the tertiary level of education, normally at university, where, it is agreed, a knowledge of English would be helpful in their academic studies. Immediate aims of learning English are defined by the requirements of examinations. Inevitably what is taught to primary and secondary level children is not a communicative knowledge of English language use, but a knowledge of how the rules of English operate. The language system is taught by means of systematic audio-lingual drill and exercise techniques based on habit formation theory of learning and a structural description of English. This may be an effective manner of teaching English usage, but it is less certain that an understanding of how these rules are related to language in use for communicative purpose is an automatic result of this instruction. What the thousands of children succeed in learning in this way is what is necessary in order to pass examinations. Whether such examinations accurately reflect the uses to which English will be put at the tertiary level is another matter altogether. Adults, on the other hand, unless they are learning a foreign language for "pleasure" at evening institutes, as a "cultural" and social experience, are generally highly conscious of the use to which they intend to put it. That use is frequently associated with an academic or professional requirement; without a knowledge of the foreign language, their development in their chosen sphere of work could be restricted or at least adversely affected. What's the relationship of English learning at different levels? | [

mmlu_train_20889 | Along the river banks of the Amazon and the Orinoco there lives a bird that swims before it can fly, flies like a fat chicken, eats green leaves, has the stomach of a cow and has claws on its wings when young. They build their homes about 4.6m above the river, an important feature for the safety of the young. It is called the hoatzin. In appearance, the birds of both sexes look very much alike with brown on the back and cream and red on the underside. The head is small, with a large set of feathers on the top, bright red eyes, and blue skin. Its nearest relatives are the common birds, cuckoos. Its most striking feature, though, is only found in the young. Baby hoatzins have a claw on the leading edge of each wing and another at the end of each wing tip. Using these four claws, together with the beak , they can climb about in the bushes, looking very much like primitive birds must have done. When the young hoatzins have learned to fly, they lose their claws. During the drier months between December and March hoatzins fly about the forest in groups of 20 to 30 birds, but in April, when the rainy season begins, they collect together in smaller living units of two to seven birds for producing purposes. Young hoatzins are different from their parents in that _ . | [
