mmlu_train_21760 | Wait for it...that sigh of relief you hearing is wives, girlfriends and partners across London celebrating the end of Movember. This year's annual moustache-growing campaign in London will surpass 2014 fundraising numbers. Last year, London men grew enough facial hair to raise S 200,000. As of Thursday, 2015 fundraising sat at $250.000, with additional money still expected to roll in. "Well, I think London is a pretty charitable community," said Lincoln McCardle, president of the London chapter. "Whether it is a food drive or Movember, we always step up and either meet or surpass the goal." As a result of last year's success, London was awarded a wrap-up gala , which took place Thursday night at Jim Bob Ray's on Richmond Street. "Up until now, the galas have been happening in Toronto, Montreal, Vancouver and Calgary," said McCandle. "We wanted to have a gala. I told the guys in head office in Toronto, to pick a number - not to tell me - but if we hit it, I want a gala in London. And we did. It is a chance to thank the people who registered, hand out a few awards and have some fun. " This year, 60 percent of the money collected in Canada will still go to prostrate cancer research with the remaining 40 percent being directed towards men's mental health. For men looking for a professional to take off their month-long growth, there are a number of "shave-off" events around the city Friday. One will be at David E. White at the corner of Richmond Street and Queens Avenue. For a $20 donation, your prized moustache will be professionally removed. Organizers are hoping to set a Guinness World Record for the most number of shaves given in a day. Started in Australia in 2003, the craze found its way to Canadian men by 2007, and in the last couple of years, Canada has collected more, setting the pace in terms of fundraising. Money raised has traditionally gone toward prostate-cancer research, which is the most frequently diagnosed cancer in men, according to Health Canada.

mmlu_train_86468 | "An apple a day keeps the doctor away." Well, milk may work in the same way! Milk is the natural food for mammalian babies. It helps them grow strong because it is rich in protein , calcium and vitamins. Milk can also help you sleep better because it calms you down. But remember to drink milk with care. Find out how old the milk is. Make sure it is fresh and hasn't gone bad. Don't drink milk when your stomach is empty. Eat some bread or corn at the same time. That'll help you take in more protein and vitamins. Doctors say teens need at least 500ml of milk a day. That's two or three cups. Milk-drinking started long ago, as early as 6,000-8,000BC. At that time people started to keep cows, sheep and goats to get their milk. Of course what you drink today isn't that fresh from the cow. People cool the fresh milk down to 40C to stop the bacteria growing. In factories, milk is pasteurized to stop it growing bad. After disinfections and packaging, it goes to the supermarkets. Yoghourt also comes from milk. People make some special bacteria to change the taste of milk and make the nutrients in it easier for people to take in. Maybe that's why it's getting more popular with people! When you drink milk , you'd better _ . | [

mmlu_train_80557 | Do you have a lucky number? What is it? Many people have a special number that they hope will bring them good luck. In Chinese culture, some numbers are believed to be lucky or unlucky based on the Chinese word that the number sounds similar to. For example, the word for the number 8 sounds similar to the word for "making a fortune ". So, people consider it a very lucky number. Some people will even spend a lot of money to have 8s in their phone numbers or vehicle license plate numbers. The opening ceremony of the Beijing Olympics began at 8:08 p.m. on August 8, 2008. The number 9 is also a lucky number because of its connection to the emperors of China. There were nine dragons on emperors' robes and Chinese myth held that the dragon has nine children. The number 9 also stands for "long lasting". That's why a man always proposes to(---)a woman with 99 or 999 roses. So what's a "bad luck" number in China? It might be 4. Many Chinese people see 4 as a "bad luck" number because it sounds similar to the character for "death". Because of this, many buildings skip the fourth floor, and simply call it the fifth floor. In Hong Kong, some buildings even skip all floors numbered with 4, such as, 4, 14, 24, 34 and all 40-49 floors. Some buildings also skip the 13th floor, as this is considered an unlucky number in many Christian countries. As a result, a building whose highest floor is 50 may have only 35 physical floors.

mmlu_train_90994 | We can't remember clearly since when we started to take our mobiles to a dinner table.This happens a lot,especially when we eat out.Once a dish comes,instead of lifting our chopsticks,we take out our mobiles and click.Later,we post the photos onto Weibo or Wechat,waiting to be"liked".Then we check our mobiles from time to time during the meal,to see whether we get"liked"or not.We just cannot leave our mobiles for only a meal. Does that sound familiar to you?Do you do that often?If not,how do you feel when others do that when having dinner with you?

mmlu_train_64712 | Imagine life without the Internet -- not being able to chat with your friends or look up information for your homework or research project. That is the reality for nearly two-thirds of our world's population, either because they cannot afford WiFi access or are located in remote, inaccessible areas. Now Google has decided to do something about that. Google's Project Loon will attempt to send balloons high up into our earth's atmosphere in 2015. Each balloon will be equipped with a mini computer and a WiFi radio that will send Internet signals over the places it is floating over. The network equipment on Google balloons will communicate with a special antenna attached to each user's home. These antennae are in turn connected to a local Internet Service Provider. Each balloon will also communicate with each other to hand over signals as one floats out of an area, and another floats in. The balloons are 15 meters wide and made of a material that is three times thicker than the plastic bag at the supermarket. This helps them defend themselves against cold temperatures and changing air pressure. Google balloons will circle the earth at a height of 20 kilometers-- in a layer of our atmosphere known as the stratosphere . This is higher than the altitude at which planes fly. Once the balloons reach the desired altitude after being released from the earth, they will ride on air currents. What keeps these balloons from flying away? They will be controlled by people at the Project Loon command center. A pump operating on solar power will fill the balloon with gas to raise it or let gas out to lower it, based on instructions. This allows the balloon to float on different air currents which are moving either clockwise or anti-clockwise. There is no doubt that this technology can bring education to many children, weather information to farmers, and communication to natural disaster areas. However, one big question remains -- will some countries be comfortable with balloons above their heads? There could be concerns about spying and other problems.

mmlu_train_58679 | What time of day can you think most quickly? Are you a morning person? Or does it take you a few hours to get your brain going? A lot of recent research suggests that we should pay attention to our body clock. It can tell us what time of day we can perform best at. Many people work best later in the morning. This is because the body's temperature takes time to rise through the day. Taking a warm shower when you wake up can help your body's temperature rise quickly. But everyone's body clock is different and some are special. Morning people will get up early and work better early in the day. Evening people will work later but work better towards the end of the day. Research shows that we're better at some activities at certain times of the day. Physical performance is at its best between 3 pm and 6 pm, so it's better to exercise later in the day. Between noon and 4 pm, people begin to pay less attention. This is because we think less quickly after a big meal. Research also shows we become sleepy around 2 pm. This is why people in Spain take a short sleep in early afternoon. Finally, it is best to eat when we're active. This allows our body to burn calories better and stops our blood sugar levels from getting too high. What is the best title for this article? | [

mmlu_train_5475 | It takes more than just practice to become an Olympian. Gold medal performances require some serious nutrition. Have you ever wondered what these successful athletes eat to stay in peak shape? Keri Glassman, a registered dietitian and founder of Nutritious Life Meals, appeared on "Good Morning America" today to give you a glimpse into the diets of some top athletes. Some of their meals could surprise you. Crazy Calorie Count _ One secret of swimmer Michael Phelps' astonishing performance in the 2008 Olympics in Beijing was consuming as many as 12,000 calories in one day. Athletes can eat like this and not gain any weight because their workouts are intense. According to Glassman, Phelps' workouts can burn 4,000 to 6,000 calories in a day, and those calories must be replenished in order to train the following day. Snacking Secrets Some athletes eat wacky (strange, unusual) foods that they swear improve their performance. Yohan Blake, the Jamaica sprinter and 100-meter world champion, has been making waves for stealing champion sprinter Usain Bolt's thunder on the track during the Olympic trials. Asked about how he gets his stamina, Blake answered that he eats 16 bananas per day, Glassman said. Jonathan Horton, the lead gymnast on the US team, has a blood sugar problem. His solution is honey. When he starts to feel shaky at the gym, he takes swigs of honey to boost his energy, Glassman said. Foods for Recovery What are the best foods to help the body recover after rigorous (strict) competition? For Olympic swimmer Ryan Lochte, the recovery meal is grilled chicken breasts with Alfredo sauce, whole-grain spaghetti and a salad with lemon juice and olive oil. Lochte, who recently cut out junk food, candy and soda, has undertaken a rigorous strength-training regimen that involves flipping tractor tires, dragging shipyard chains and tossing beer kegs, Glassman said.

mmlu_train_11594 | Scientists from the United States say they have found fish and other creatures living under key waters in Antarctica. They made the announcement after completing three months of research at the Ross Ice Shelf, the world's largest floating ice sheet. The researchers hoped to find clues to explain the force of the melting ice and its effect on sea level rise. Reed Scherer and Ross Powell are with Northern Illinois University in DeKalb, Illinois. They just finished up their research on our southernmost continent. Money for the project came from America's National Science Foundation. "We chose a study site where, in the first year ,We went into the subglacial lake and tried to understand the environment in there, both ecologically and in terms of the ice dynamics about how the lake operates ,and how the sediment underneath the ice sheet operates, as well, because it's the water and the sediment underneath the ice that controls how fast the ice is flowing into the ocean" says Ross Powell, who led the investigation. The team included scientists ,engineers, machinery and other supplies across the ice from the main U.S. scientific base at Mc Murdo Station to the researcher's camp .The camp was near a subglacial lake ,where an earlier study took place, Ross Powell says the latest study may provide evidence that can help predict the effect of climate change on rising sea levels. "What we have found is that these are very sensitive areas to the stability of how dynamic the ice is and how fast the ice may react to increases of melting both from the ocean and the atmosphere." Among the new instruments built for the project was a powerful hot water drill. The researchers used the drill to dig down some 740 meters. They collected water ,sediment and other material from the grounding zone. Working around the clock before the deep hole refroze, they sent a video camera down to the 400-square-meter undersea area. Reed Scherer says the video images they saw in the Command Center were a total surprise. "It's a very mobile environment. The bottom is changing constantly. And so the things that we saw were all very mobile organisms, things that swim and some things that crawl. And obviously they are getting enough nutrition that they can thrive, Some of the little crustacean-like creatures called amphipods that we saw swam quite quickly and were quite active." This is the farthest south that fish have ever been seen. How did the creatures get here? What do they feed on? And what effect will the retreating ice have on them? Ross Powell says the ice and sediment cores taken from the grounding zone can offer clues. "We know that the ice is melting there at the moment and so by opening up the cores once they get back, we hope to be able to understand what the ice was doing in the past ,relative to what it is doing now. And because it is melting so fast or seems to be melting fast at the moment, we anticipate that there will he some differences that we'll see in the history of the ice sheet from the sediment cores, once we open them up ."But Ross Powell says the work raises more questions than it answers. What made the researchers surprised when they saw the video images? | [

mmlu_train_33452 | Now AIDS has become one of the most dangerous killers for human beings. The whole world is in danger of AIDS. But the situation in rich countries is not the same as that in poor countries. According to a research, the most serious area is Africa. Throughout Africa, whole communities are being _ by AIDS. Mothers, fathers, teachers and farmers are dying in thousands, day after day. Why is it that most people with HIV live in the world's poorest countries? Lack of education and health care makes people easy to be infected ; poverty and the constant search for work and food keep them on the move; casual work and casual sex leave women particularly easy to be infected. As a result, the disease spreads to even more people. Those who are already malnourished very soon become sick. Parents die, leaving children who are infected. It's a dangerous circle. When Pep Bonet visited Nchelenge in northern Zambia in 2003, he found one person in four was HIVpositive(HIV). There was a closed and fearful atmosphere. No one wanted to admit to their HIV identity, and women who were HIV positives were often beaten or driven out of their home. Mothers left home and children became orphans. People lost hope, and the light went out of their eyes.

mmlu_train_27940 | Sharks are among the oldest animals on Earth. There are hundreds of kinds of sharks. Most are about two meters long. The dogfish shark, however, is less than twenty centimeters in length. A shark has an extremely good sense of smell. It can find small amounts of matters in water, such as blood, body liquids and chemicals produced by animals. These powerful senses help sharks find their food. Sharks eat fish, other sharks, and plants that live in the ocean. Sharks grow slowly. About forty percent of all sharks lay eggs. The others give birth to live young. Some sharks carry their young inside their bodies as humans do. Some sharks are not able to reproduce until they are twenty years old. Most reproduce only every two years. And they give birth to fewer than ten young sharks. For this reason, over-fishing of sharks is of special danger to the future of the animal. Sharks are important for the world's oceans. They eat injured and diseased fish. Their hunting activities mean that the numbers of other fish in ocean waters do not become too large. This protects the plants and other forms of life that exist in the oceans. People hunt sharks for sport, food, medicine and their skin. Experts say the international market for some kinds of sharks has increased because many parts of a shark are valuable.Collectors pay thousands of dollars for the jaws of a shark. Shark liver oil is a popular source of Vitamin A. The skin of a shark can be used like leather. In Asia, people enjoy a kind of soup made from shark fins. Experts say a fisherman can earn a lot of money for even one kilogram of shark fins. Sharks are among the oldest animals on Earth, but some sharks are in danger of disappearing from Earth.

mmlu_train_26024 | Narayana Hrudayalaya, a complex of health centers based in southern India, offers low-cost, high-quality specialty care in a largely poor country of 1.2 billion people. By thinking differently about everything from the unusually high number of patients it treats to the millions for whom it provides insurance, the hospital group is able to continually reduce costs. Narayana Hrudayalaya's operations include the world's largest and most productive cardiac hospital, where the average open-heart surgery runs less than $2,000, a third or less what it costs elsewhere in India. Narayana Hrudayalaya's origins date back to 2001, when it built its massive cardiac center on the outskirts of Bangalore. But it has expanded since then into what founder Dr. Devi Shetty calls a "health city," a series of centers specializing in eye, trauma, and cancer care. Narayana Hrudayalaya now manages or owns hospitals in 14 other Indian cities. Expanding access is paired with a ongoing focus on efficiency. Typically, says Shetty, private hospitals in India focus on patients who can easily afford treatment. "We did it the other way around," he says. "This hospital is for poor people, but we also treat some rich people. We don't look at people who are sgabbily dressed and have trouble paying as outsiders. " Narayana Hrudayalaya's flagship hospital has 3,000 beds and negotiates for better prices and buys directly from manufacturers, cutting out distributors. In addition to cost-cutting, Narayana Hrudayalaya finds creative ways to make the economics work. The company started a micro-insurance program backed by the government that enables 3 million farmers to have coverage for as little as 22 cents a month in premiums . Patients who pay discounted rates are in effect compensated by those who pay full price Doing something--doing more, actually--is the point. By 2017, Shetty, 58, plans to expand from 5,000 beds throughout India to 30,000. Before becoming one of India's best-known health-care entrepreneurs, Shetty was its best-known heart surgeon. He was interrupted in surgery one day during the 1990s by a request to make a house call. "I said, 'I don't make home visits,' " Shetty says, "and the caller said, 'If you see this patient, the experience may transform your life.' " The request was from Mother Teresa. Inspired by the her work with the poor, he then set out to create a hospital to deliver care based on need, not wealth. "One lesson she taught me," he says, quoting a saying he keeps framed in his office, "is ' .' " Why did Shetty build the massive cardiac center in 2001? | [

mmlu_train_88446 | Almost everyone has dropped some food on the floor and still wanted to eat it.If someone saw you drop it, he or she might have shouted, " 5-second rule!" This so-called rule says food is OK to eat if you pick it up in five seconds or less.But is that true? Professor Anthony Hilton from Ashton University, UK, tested the rule with his students.They found that food dropped for five seconds is less likely to contain bacteria than if it sits there for longer. For the study, Hilton and his students tested a lot of foods----bread, pasta, cookies and candy--to see how much bacteria they had when they made contact with the floor.They allowed the food to lie on the different types of flooring--carpet , laminate and tile -- for three seconds to 30 seconds. Not surprisingly, the longer the food was on the floor, the more bacteria it had.And the type of floor where the dropped food landed had an effect.Bacteria are least likely to transfer from carpet, while they are most likely to transfer laminate or tiled surface after more than five seconds. The study also found that the wetter the food, the more likely it was to pick up bacteria.Although most people are happy to follow the 5-second rule, eating food dropped on the floor still carries an infection risk."It very much depends on which bacteria are on the floor at the time."

mmlu_train_50313 | There was good news last week for people who struggle to get eight hours of sleep a night: they may not need so much shut-eye after all. Researchers from UCLA and elsewhere looked at sleep habits of remote hunter-gatherers in Tanzania, Namibia and Bolivia -- groups with pre-industrial lifestyles whose sleep patterns are believed to reflect those of ancient humans. The researchers found that, on average, members of each group sleep a bit less than six and a half hours a night. The study, published in the academic journalCurrent Biology, indicates that "natural" sleep is less than eight hours a night and that modern society's numerous electronic distractions aren't necessarily to blame for people getting just six or seven hours of sleep. "The story that often gets out is that if you sleep for less than seven hours, you're going to die early," he told me. "That's not true." Yet Americans are addicted to getting more sleep -- and on turning to medical shortcuts to help them. According to the Centers for Disease Control, as many as 70 million U.S. adults suffer from sleep disorders or sleeplessness. Only a third of Americans get the government's recommended seven to nine hours of sleep a night. About 9 million American adults use sleeping pills to help get a good night's rest, the CDC found. Siegel said the number of people relying on medicines "has gone up rather rapidly since then." Industry consulting firm GlobalData estimates that worldwide sales for sleeplessness medicines will run about $1.4 billion next year and reach $1.8 billion by 2023, recovering from lower sales in recent years because of cheaper generics hitting the market. Dr. Roy Artal, a sleep specialist in West Los Angeles, said it's understandable that busy people in today's go-go world would turn to medicines to speed up the sleep process. But all they're doing is building a reliance on powerful drugs for relatively little improvement. "There's no magic pill that makes us sleep when we want and wake up when we want," Artal said.

mmlu_train_71088 | It seems that there's a good reason why dogs are always seen as man's best friend. Scientists have found that dogs are the only animals that can read emotion in faces much like humans. The finding suggests that like an understanding friend, dogs can see if we are happy, sad, pleased or angry. When humans look at a new face, their eyes usually look across the left, falling on the right hand side of the person's face first. A possible reason for this is that the right side of the human face is better at expressing emotions. Scientists have now shown that pet dogs also have "left gaze bias ", but only when looking at human faces. No other animal has been known to do like this before. Dr. Kun Guo showed 17 dogs pictures of human, dog and monkey faces as well as something else with his team. The dogs' eyes and heads show a strong left gaze bias when the animals see human faces. But this did not happen when they were shown other pictures, including those of dogs. Guo suggests that over thousands of years living with humans, dogs may have developed the left gaze bias as a way to guess our emotions. "Recent studies show that the right side of our faces can express emotions better than the left. If true, then it makes sense for dogs and humans to see the right hand side of a face first."

mmlu_train_32601 | When scientists accidentally killed what turned out to be the world's oldest living creature, it was bad enough. Now, their mistake has been worsened after further research found it was even older - at 507 years. The ocean quahog, a type of deep-sea clam, was dredged alive from the bottom of the North Atlantic near Iceland in 2006 by researchers. They then put it in a fridge-freezer, as is normal practice, unaware of its age. It was only when it was taken to a laboratory that scientists from Bangor University studied it and concluded it was 400 years old. The discovery made it into the Guinness Book of World Records. However, by this time, it was too late for Ming the Mollusc , named after the Chinese dynasty when its life began. Unfortunately researchers who calculated Ming's age killed it instantly by opening its shell. The researchers opened the ancient clam up to judge its age by counting growth rings inside. But the rings were so close together that scientists ended up having to count the rings on the outside to be accurate, leading CBS journalists to point out that if scientists had just started there, Ming could have lived on. Now, after examining the quahog more closely, using more advanced methods, the researchers have found the animal was actually 100 years older than they first thought. Dr Paul Butler, from the University's School of Ocean Sciences, said: "We got it wrong the first time and maybe we were a bit hasty publishing our findings back then. But we are absolutely certain that we've got the right age now." The mollusc was born in 1499 - just seven years after Columbus discovered America and before Henry VIII had even married his first wife, Catherine of Aragon in 1509. A quahog's shell grows by a layer every year, in the summer when the water is warmer and food is plentiful. It means that when its shell is cut in half, scientists can count the lines in a similar way that trees can be dated by rings in their trunks. Jan Heinemeier, associate professor at the University of Denmark, who helped date Ming, told Science Nordic: "The fact that we got our hands on a 507-year-old animal is incredibly fascinating, but the really exciting thing is of course everything we can learn from studying the mollusk."

Snacks are a great way to satisfy that hunger and get all the vitamins and nutrients your body needs. But you need to pay attention to what you eat. Filling your stomach with a lot of fries after class may give you a short-time help, but a snack high in fat and calories will only slow you down in the long time. To keep energy levels going---and avoid gain weight---keep away from foods like candy or soda. Look for foods like bread and grains and combine them with some food like peanut butter or low-fat milk or cheese. Choosing healthy snacks means shopping smart. Be careful of the health instructions on food bags. Here are some things to watch out for. That something is "all natural " doesn't necessarily mean that it's nutrients. For example, "all natural" juice drinks or sodas can be filled with sugar (which means they'll be high in calories and give you little nutrition.) A granola bar is a good example of a snack that people think is healthy.

mmlu_train_34502 | Imagine going to sleep then waking up speaking another language. It may sound impossible, but it's actually happened. The phenomenon of being able to suddenly speak another language is known as"Xenoglossia", from the Greek words"xenos"(foreigner)and "glossa"(language). _ once happened to a 13yearold girl from Croatia. After being unconscious because of a disease for 24 hours in 2010,she woke up speaking fluent German. The girl, who came from the town of Knin in the south of Croatia,was studying German at school but she'd only started recently. Her parents said that she'd been reading German books and watching German TV at home, but that she wasn't fluent in the language.However ,since waking up, she's been able to communicate "perfectly"in German.What's really strange is that she's now unable to speak Croat,her mother language.Doctors at Split's KB Hospital have asked some experts to examine the girl as they try to find out what caused the change.Dr Mijo Milas said,"In earlier times this would have been considered as a miracle ;we prefer to think that there must be an explanation--it's just that we haven't found it yet." In 2007,Matej Kus from Czech became unconscious after a motorbike accident. On waking up 45 minutes later,he could speak fluent English.Matej was only 18 years old at the time, and had just started studying the language and so was at a low level.Peter Waite,Kus's teammate said,"I couldn't believe what I was hearing.It was really clear English.It was unbelievable to hear him talk in unbroken English."Unluckily,Matej's new language skills didn't last.Two days later, when he recovered fully from the accident, he'd completely forgotten his English. We still don't know exactly what happened to the two people. Perhaps scientists will discover something new and exciting. But until then, keep studying!

But experts believe that there is no link between cold weather and catching colds. So why are we particularly easy to catch colds this season? Internal Medicine expert, Dr Meenakshi Jain of Max Hospital says, "One reason could be because people are likely to stay indoors, so the virus can spread easily. Also the virus grows strong and healthy under wet conditions." The common cold can be caused by any of up to 250 kinds of virus. The most common group of them is the kind of virus that hits the nose, which is called rhinovirus . Rhinoviruses cause a third and half of all common colds. "The kind of virus is spread through the nose and respiratory passages , by touch, and by contact with particles in the air that are created by sneezing or coughing," says Dr Jain. There is no way to treat the common cold. However, there are some tips that can help. Wash your hands regularly, so that germs get killed. Don't touch your eyes, nose or mouth, which can limit your chances of infection . Don't share drinking glasses with anyone as this will prevent the spread of the virus. Drink lots of water.

mmlu_train_39101 | Every vehicle needs tires, but eventually they wear out. Roads wear out too, and they often need repairing. But new research by a pair of teens suggests the rubber from worn-out tires could lengthen the lifetime of asphalt pavement. Also roads made with this material might need fewer patches . The young researchers presented their findings in May, 2014, as finalists at the International Science and Engineering Fair (ISEF). The 64th annual Intel ISEF shows some of the best high school science projects from around the globe. Many roads are made with asphalt, which requires much petroleum. But Jordan is a country that has very few oil wells or other sources of petroleum, notes Mohammad Salameh, who is a 10th-grader at the International School in Amman, Jordan. For Jordan, having to import most of the country's petroleum adds greatly to its cost, the teen notes. The extra expense means that there's less money to build and maintain roads. That has resulted in poorer quality roads. As a result, those roads need to be patched almost constantly. Therefore, 16-year-old Mohammad and his research partner, 15-year-old classmate Adam Belaid, came up with the idea of adding rubber to asphalt. But that rubber can come from old tires. Even a worn-out tire contains much rubber, which means the material should be plentiful, says Mohammad. Drivers in Jordan replaced 9 million tons of tires between 2006 and 2010, and only 0.3% of that rubber was recycled. That leaves much rubber that could possibly go into road construction. But first the teens had to show adding rubber to asphalt resulted in better roads. To test their idea, they created several different asphalt-rubber recipes. They also tried out different temperatures at which the mix was heated. And their tests suggested that when the surfacing material includes 8% rubber, it should hold up for 10 to 15 years of traffic instead of the normal 5 years. And their recipe should reduce the need for patching worn areas from once a year, to maybe once every 5~7 years in the future. It can be learnt from the passage that . | [

mmlu_train_55553 | It turns out that nodding off in class may not be such a bad idea after all, as a new study has shown that going to sleep shortly after learning new material is the best way to remember it. According to US lead author Jessica Payne, a psychologist at the University of Notre Dame in Indiana, nodding off after learning something new is like "telling" the sleeping brain what to remember. Along with colleagues, she studied 207 students who habitually slept for at least six hours per night.Participants were casually selected to study declarative , semantically related or unrelated word pairs at 9am or 9pm, and returned for testing 30 minutes, 12 hours or 24 ours later. Declarative memory refers to the ability to remember facts and events with awareness, and can be broken down into episodic memory (memory for events) and semantic memory (memory for facts about the world).People routinely use both types of memory every day--recalling where we parked today or learning how a colleague prefers to be addressed. At the 12-hour retest, memory overall was better following a night of sleep compared to a day of wakefulness. At the 24-hour retest, with all subjects having received both a full night of sleep and a full day of wakefulness, subjects' memories were better when sleep occurred shortly after learning, rather than following a full day of wakefulness. "Our study confirms that sleeping directly after learning something new is beneficial for memory.What's new about this study is that we tried to shine light on sleep's influence on both types of declarative memory by studying semantically unrelated and related word pairs," Payne said. "Since we found that sleeping soon after learning benefited both types of memory, this means that it would be a good thing to practise any information you need to remember just before going to bed.In some sense, you may be 'telling' the sleeping brain what to remember."

mmlu_train_6545 | Cooking food over a smoky fire is found everywhere in the world. It is often difficult to find wood for the fire. People who do not have wood must spend large amounts of money on cooking fuel. However, there is a much easier way to cook food using energy from the sun. Solar cookers, or ovens, have been used for centuries. A Swiss scientist made the first solar oven in 1767. Today, people are using solar cookers in many countries around the world. People use solar ovens to cook food and to heat drinking water to kill bacteria and other harmful organisms. There are three kinds of solar ovens. The first is a box cooker. It is designed with a special wall that shines or reflects sunlight into the box. Heat gets trapped under a piece of glass or plastic covering the top of the cooker. A box oven is effective for slow cooking of large amounts of food. The second kind of solar oven is a panel cooker. It includes several flat walls, or panels, which directly reflect the sun's light onto the food. The food is inside a separate container of plastic or glass that traps heat energy. People can build panel cookers quickly and with very few supplies. They do not cost much. In Kenya, for example, panel cookers are being manufactured for just two dollars. The third kind of solar oven is a parabolic cooker. It has rounded walls that aim sunlight directly into the bottom of the oven. Food cooks quickly in parabolic ovens. However, these cookers are hard to make. They must be re-aimed often to follow the sun. Parabolic cookers can also cause burns and eye injuries if they are not used correctly. You can make solar ovens from boxes or heavy paper. They will not catch fire. Paper burns at 232 degrees Celsius. A solar cooker never gets that hot. Solar ovens cook food at low temperatures over long periods of time. This permits people to leave food to cook while they do other things. To learn more about solar cooking, you can write to Solar Cookers International. The postal address is nineteen-nineteen Twenty-First Street, Sacramento, California, nine-five-eight-one-one, USA. Or you can visit the group's Internet Web site. The address is www.solarcooking.org. How long is the first solar cookers invented? | [

And international agreements that laid out the standards, regulations and practices gave rise to a global mobile phone industry. To be honest, the world's first mobiles were not so attractive and the range of effectiveness wasn't very good. But they became a must-have among those wealthy people who could afford that. However, by advantage of GSM which has many different elements to it, we can all enjoy the ability to go around the world in 217 countries, land in that country and know that a phone would work. There are other cell phone systems using different technology in the world. The majority of the United States and parts of South America have been using something called CDMA which is very rare in Europe. In some Asian countries like China, GSM and CDMA both exist at the same time. But the GSM Association claims 85% of the global mobile phone market. They estimated there are now about 2.5 billion different users who make more than 7 trillion minutes of calls everyday, and that's not all. 20 years later, the mobile phone is so much more than just a phone. You can use it to send text messages, take pictures, show video, even surf the internet.

mmlu_train_46461 | The Worldwatch Institute said in 2011 far too many people were living with less than they needed. It says, for example, nearly one billion people were hungry arid just as many were illiterate . Worldwatch Institute's Danielle Nierenberg said while a billion people went to bed hungry each night, it wasn't because of a lack of available food. "We produce more than enough food in the world to feed not only the 7 billion people who are on earth today, but 9 to 11 billion people. By 2050, we expect the population to be about 9 and a half billion people and we now produce enough food to feed all of those people. But the question is really one of how do we get food to the people who need it the most. Poverty really delays the progress of allowing people to eat well. Not just getting enough basic crops, but being able to buy fruits and vegetables and the things that will really nourish them," she said. The director of the Nourishing the Planet Project said besides poverty and a lack of access to food, much food is simply lost. Worldwatch estimates 1.3 billion tons of food is wasted each year. "20 to 50 percent of the global food harvest is wasted before it can ever reach people's stomachs. And this is really a moral problem when you consider all of the people who are hungry in the world. The good news about that 20 to 50 percent of global food waste number is that it's easy to prevent food waste.We can do it in our homes. Consumers can do a lot to prevent food waste by planning meals better, by not buying too much food. In the developing world there are storage systems that are beginning to be put in place that help farmers protect their food from crop diseases or molds ,"she said. Nierenberg said prevention measures can be put in place all along the food chain. While it may not seem obvious, the Worldwatch Institute project director said malnutrition and illiteracy are closely linked. "When people, especially farmers, don't have the education that they need to live productive lives, they can't learn new skills. And in sub-Saharan Africa, women farmers, especially, don't have access to education. This prevents them from not only learning new cropping techniques and learning new technologies; it also prevents them from being able to get financial and banking services. They can't have bank accounts. They can't buy land. They can't buy the inputs that they need to make their crops more productive," she said. Nierenberg said despite the many challenges, Worldwatch is hopeful for the future.

mmlu_train_22560 | At the U.S. Open championships in Flushing Meadows, New York last week, the United States Tennis Association (USTA) held an unusual youth press conference . I say "unusual" because the main idea wasn't to promote the sport for young children. Yes, there was a youth tennis exhibition in which a group of fresh-faced kids from the area showed off their well developed skills. They used junior racquets and larger, low-pressure balls on a half-size tennis court-a way the organization supports as a means to help children have early success and stick with the game. But the event's real purpose was to help parents realize the importance of introducing kids to all kinds of athletic programs rather than focusing specially on one. _ may sound like something easy to do, but it's not. In today's achievement-oriented ( ) environment, children are being pushed to specialize in a single sport-whether it's tennis, hockey, soccer, or gymnastics - at ever-younger ages. Tom Farrey, executive director of the nonprofit Aspen Institute Sports & Society Program, says year-round sports programs are now offered down to age 5, too early an age for a child to limit himself or herself to a single activity. While parents naturally want the best for their child, they are being pressured by coaches to let him or her stick with one thing. The result: More kids under age 12 are suffering injuries or, worse, burnout. According to the Aspen Institute's report, Project Play, fewer kids today are staying involved with sports than five years ago, partly because of forced specialization. Today's children are already on track to live shorter, less healthy lives than their parents because of obesity and related diseases, and this trend is only worsening matters. Multi-sport participation, however, leads to better performance (because kids get a chance to develop different sets of skills ) and greater enjoyment of the game, says Farrey. The headlining athletes at the event repeated the idea that having kids do more than one sport is a plus (good for them). According to Tom Farrey, which of the following statements is TRUE? | [

mmlu_train_10379 | Maybe you're really busy. Maybe you don't have much to say. Or maybe you're just lazy. Not a problem. This free service works by letting you broadcast a group text message to your friends' mobile phones from either your own phone, an instant message or an online form at twitter.com. All your notes are then stored and displayed on your personal profile page on the site, which includes links to your friends' Twitter pages, a thumbnail picture of your choice, and a short bio. All this is what the new service Twitter can bring you. Just remember to keep it short: posts are limited to 40 characters, and the topic is, invariably, "What are you doing?" More often than not, it turns out, Twitter's 100,000 members--twice as many as it had just a month ago, according to Twitter business development director Biz Stone--are simply killing time. Even Presidential hopeful John Edwards is on it, although he seems to be the only one thinking about more than lunch. As I type this, Caroline is mulling over some Girl Scout cookies, Ian _ Hocking is "waiting for Jessica to arrive so we can eat!" and Hlantz is "having a nice cup of Soft Starmint tea." The chatter about Twitter turned into a virtual roar two weeks ago during the South by Southwest Multimedia Festival in Austin, Texas, when the barebones service owned by Blogger founder Evan Williams, 34, was named the best blogging tool and attendees used it to meet up at parties. Nevertheless, Twitter has been the top term on blog search engine Technorati for the past two weeks. Plenty of people would happily have Twitter silenced, rather than tolerate the beeping alert for yet another new text message.

mmlu_train_24225 | India was once part of the British Empire, but thanks to modern technology and a booming economy, it has turned the tables on its former colonial master. Indian tutors are helping to teach math to British children over high-speed Internet connections. Early results suggest the idea is improving exam results. But not everyone is happy at this "outsourcing" of tutoring. It's 3:30, and pupils at Raynham Primary School in London are gathering for their after-school maths lessons. Five time zones-- thousands of kilometers away--their math tutors are also arriving for class. High-speed Internet has made it possible for Indian tutors to teach British pupils in real time. Each pupil gets a dedicated one-to-one online tutor. The students work with activities on their computer screen and wear a headset and microphone to talk to their tutor. The class teacher, Altus Basson, says he has seen an improvement in results. "There are some children who've really rocketed in their results. Children who struggleto focus in class focus a lot better on the laptops. The real advantage is that each child gets a focused activity and a single tutor," he said. Such individualized teaching is the core idea of Brightspark Education, the company that provides the online tutoring, says founder Tom Hooper. "Children today feel very confident online; they feel very engaged; they feel very in control. And that's half the battle with education.Give them control, make them feel confident and enjoy their learning and you'll see them start to improve and embrace it," he said. Raynham Primary School is among the first in Europe to try online tutoring. At between $20 and $25 an hour, it's about half the cost of face-to-face coaching. But some people say an Internet connection is not enough of a connection for teaching and learning. Kevin Courtney is deputy General Secretary of Britain's National Union of Teachers. "We think, there's a really important emotional connection between a teacher and a child whether it's a whole class or whether it's one-to-one. You need that immediacy of feedback and we're not convinced that that can happen across an Internet connection. In one of the wealthiest.countries in the world, we think that we can afford to have teachers with genuine emotional connection there with the children," he said. Brightspark Education says the online tutoring is used only as an addition to supplement regular teaching. The company says its service does not represent a threat to teachers' jobs in Britain. Parents say they're very satisfied with the results they've seen. And what about the children?Children: "I love it!"I love it!"I hate maths!" So math--or, as the British call it, maths--is still not everyone's favorite subject even with the latest technology to teach it. What's the best title for this passage ? | [

They're just some of the topics covered in a new book by University of Sussex academics, which is helping student doctors to consider the importance of psychology in medical practice. Psychology for Medicineis the first textbook of its kind, providing medical trainees and new doctors with all the relevant psychological knowledge they need. Previously, students had to refer to many different books for the relevant psychology. The book, by Sussex psychologists Dr. Sussex Ayers and Dr. Richard de Visser, has been well received by fellow academics and medical doctors and was finished with the help of the students and staff of the Brighton and Sussex Medical School. The studentsproofread the chapters, provided ideas for the content and even modeled for the photographs. The book provides a solid grounding in psychological study relevant to medicine, along with practical tips and advice for practice. One student, Simon Hall, drew cartoons for the book. The study psychology is important for doctors for a number of reasons. Psychological and physical symptoms are highly related. Up to a third of patients will have psychological disorders, while physical causes are usually only found in around 15 per cent of people's symptoms. In treatment, a lot of the effect drugs can be due to patients believing they will recover rather than the drug itself. Dr. Ayers says, "The important thing about this book is that it's applied science --- it shows why psychology is important to medicine and how we should use it. The book's presentation is really important. It's not just lots of theory, but full of tips and advice so that students can take what they learn in the classroom and apply it to real-life situations."

After its first man in space, China plans a space laboratory, a lunar orbiter to look for valuable elements and minerals, robot landings on the moon and then the human touchdown. The price of space exploration is enormous. Russia and the US, the only two countries to have achieved manned flight, are struggling to keep their new investment, the international space station. But China, which has a long tradition in physics, mathematics and engineering, finds its doctoral graduates welcomed in the US and Europe for decades. And it has been able to learn from 40 years of pioneering successes and mistakes by the USSR and the USA. Space flight is a gamble and the stakes are high. If successful, China could become a member of the world's most exclusive club, set up a second home on the moon and get a powerful hand at the strategic bargaining table. Two designers from the Shenzhou III project said that 12 astronauts now are undergoing intensive training. One more unmanned space flight is planned before the first manned launch.

mmlu_train_85066 | In 2004, three young men went to a dinner party in San Francisco. Afterward ,they wanted to share a video from the party with their friends. They wanted to send it over the Internet. But at the time, the process of sharing videos that way was difficult. Using e-mail did not work and the friends complained that there, was no website to help them. So they created their own. They called their website YouTube. It made sharing videos easy, so the website soon became very popular. People watched 2.500 million videos in the first six months! Today, more than 70,000 new videos go up on YouTube each day. People watch more than 1,000 million videos a day. Many last no more than 10 minutes. These videos show all kinds of things, from sleeping cats to earthquakes. Most of the filmmakers are not professionals. They are just everyday people making videos, and they use the website in many interesting ways. First many people use YouTube to entertain others. One example is Judson Laipply. He made a funny dance video and put it on YouTube in 2006. People watched the video more than 10 million times in the first two weeks. Now people stop Judson on the street to ask, "Are you the dance guy on Youtube?" Some people have invited him to dance at their parties. A few women even asked to marry him. Judson wants to make more dance videos, and people look forward to seeing them. Other people use YouTube to advertise a business. David Taub does this. He is a guitar teacher and he sells videos of guitar lessons on his own website. He wanted to increase his business, so he put short videos with free lessons on YouTube. People enjoyed watching the lessons on YouTube, and afterward, many decided to go to David's own website. Now David sells hundreds of guitar lesson videos each week. People also use YouTube to help others. Ryan Fitzgerald is one example. Ryan is friendly young man who knows that some people are lonely and have no one to talk to. One day, he made a video of himself for YouTube. In the video, he gave his phone number and invited people to call him. In less than a week, he had more than 5,000 calls and messages from all over the world. These days, he is very busy talking on the phone. He helps people when he can, but mostly, he just listens, like a friend. Finally, some filmmakers use YouTube in a more serious way. They want to inform people about important events happening in the world. For example, they show clips of videos from countries at war, or they show people in need of help after a storm. Sometimes TV news shows do not give enough information about these events. Thanks to YouTube filmmakers, people can go to their computers and learn more.

mmlu_train_17152 | Nobel, who was born in Stockholm, is a great scientist famous for his dangerous experiments. Nobel studied in the USA and then Russia between 1850 and 1859. After his return, he started researching into bombs. As is known, bomb is dangerous to life, but Nobel was working under that condition. Once a big explosion in his lab completely destroyed the lab and caused some deaths. After that he had to experiment on a boat in a lake. He received criticism and satire , but he proceeded with the work rather than losing heart. From 1860s to 1880s, Nobel made many achievements and his inventions were first used in building roads and digging tunnels. Most of the bombs were safer and more possible to be controlled. Even at the end of the 20th century, we still used his methods. Nobel had many patents in Britain and other European countries. He was quick to see industrial openings for his scientific inventions and built up over 80 companies in 20 different countries. Indeed his greatness lay in his outstanding ability to combine the qualities of an original scientist with those of a forwardlooking industrialist. But Nobel's main concern was never with making money or even with making scientific discoveries. Seldom happy, he was always searching for a meaning to life, and from his youth, he had taken a serious interest in literature and philosophy. His greatest wish, however, was to see an end to wars, and thus peace between nations, and he spent much time and money working for this cause. To follow his will, a fund was set up to encourage people to make great progress in physics, chemistry, physiology , medicine, literature and peace.

At 17, his father tired to persuade him not to become a mathematician because he may lead a poor life being a mathematician, and so von Neumann agreed to study chemistry as well. In 1926, at 23, he received a degree in chemical engineering and a Ph.D. in mathematics. From then on, mathematics provided well enough for him, and he never had to turn to chemistry. In 1930, von Neumann visited Princeton University for a year and then became a professor there. His first book was published in 1932. In 1933, the Institute for Advanced Study was formed, and he became one of the 6 full-time people in the School of Mathematics(Einstein was one of the others) World War II hugely changed von Neumann's areas of interest. Until 1940 he had been a great pure mathematician. During and after the war, he became one of the best mathematicians who put mathematics theories into practice. During the last part of the war he became interested in computing machines and made several fundamental contributions After the war, von Neumann continued his work with computers, and was generally very active in government service. He received many awards, was president of the American Mathematical Society and was a member of the Atomic Energy Commission. He died in 1957 of cancer. Von Neumann made several great contributions and any one of them would have been enough to earn him a firm place in history. He will be remembered as one of the greatest minds of the 20th century. Von Neumann really was a legend in his own time, and there are a number of stories about him. His driving ability is a part of his legend.

mmlu_train_31277 | Note: 1gigawtt =" 1000" megawatts SAN FRANCISCO -- Apple is cleaning up its manufacturing operations in China to reduce the air pollution caused by the factories that have assembled hundreds of millions of iPhones and iPads during the past eight years. The world's most valuable company is working with its Chinese suppliers to eventually produce 2.2 gigawatts of solar power and other renewable energy. The commitment announced Wednesday represents Apple's latest attempt to prevent the popularity of its devices and digital services from increasing the carbon emissions that are widely believed to change the Earth's climate. Apple Inc. estimates 20 million tons of greenhouse gas pollution will be avoided as more of its suppliers rely on renewable energy between now and 2020. That's like having four million fewer cars on the road for a year. Panels capable of generating about 200 megawatts of solar power will be financed by Apple in the northern, southern and eastern regions of China, where many of its suppliers are located. The company is teaming up with its Chinese suppliers to build the capacity for the remaining 2 gigawatts of renewable energy, which will be a mix of solar, wind and hydroelectric power. Foxconn, which runs the factory where the most iPhones are assembled, is pledging to contribute 400 megawatts of solar power as part of the 2-gigawatt commitment. The solar panels to be built by 2018 in China's Henan Province are supposed to produce as much renewable energy as Foxconn's Zhengzhou factory consumes while making iPhones. Apple has made protecting the environment a higher priority since Tim Cook replaced the late Steve Jobs as the company's CEO four years ago. "Climate change is one of the great challenges of our time, and the time for action is now," Cook said in a statement. "The transition to a new green economy requires innovation, ambition and purpose." Apple just completed projects in China that generate 40 megawatts of solar energy to cover the power required by its 24 stores and 19 offices in the country. All of Apple's data centers, offices and stores in the U.S. already have been running on renewable energy. "When you look at all the air pollution in China, all the manufacturing that is done there has a lot to do with it, so this is a significant step in the right direction," said Gary Cook, a senior analyst for Greenpeace, a group devoted to protecting the environment. Apple also has a financial motivation to help make China a better place to live. The greater China region is Apple's second biggest market behind the U.S. Tim Cook has made it clear that he wants the company to make even more progress as rising incomes enable more of China's population to buy smart phones and other gadgets. Apple can easily afford to go green. The company had $203 billion in cash at the end of June. This story has been reflected to correct that Apple and its suppliers haven't set a timetable for producing the 2.2 gigawatts of renewable energy in China.

mmlu_train_50996 | Your car is a necessary part of your life. You use it every day. Of course, you want to hold on to it so you make sure it has the latest alarm and immobilizer. But despite all these, cars like yours are still stolen every day. In fact, in this country, one car is stolen almost every minute! And if your car is stolen, you only have a 50:50 chance of seeing it again. Each year, car crime costs nearly PS3 billion. Of course, if you're insured, you won't lose out, or will you? Firstly, you will have to pay extra insurance later on, and then you may not be offered the full amount by the agent. You will probably have to hire a car and you will also lose the value of the contents and accessories in the car. Now comes the solution. An RAC Trackstar system, hidden in one of 47 possible secret locations in your car, is the key of our system. If your car is stolen, radio signals are sent at twenty-second intervals from the car to the RAC Trackstar National Control Center via a satellite network. Then a computer gives the vehicle's exact location, speed and direction. The RAC Trackstar National Control Center, which operates 24 hours a day, 365 days a year, will immediately inform the police in the area where the car is located. Because the police receive information every twenty seconds, they will always know the vehicle's location. Once the thief has been arrested, your car will be returned to you. RAC Trackstar is unique in being able to provide the National Control Center with details of the exact location of your car, its speed and direction. And speed is the key to successful recovery of a stolen vehicle. RAC Trackstar Control will immediately tell the police if you report your car stolen and under the 24-hour Guardian Option. _ will also tell you if your car has been stolen. RAC Trackstar's constant updates mean the police are kept informed of the car's location. All these greatly improve your chances of seeing your car again.

mmlu_train_50615 | Our risk of cancer rises dramatically as we age. So it makes sense that the elderly should be routinely screened for new tumors -- or doesn't it? While such vigilant 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 biopsies and surgeries to remove cancer, which can cause side effects, while the cancers themselves may be slow-growing and may not pose 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 riotous reaction among doctors, patients and advocacy 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 prior personal experience with the disease, should continue to get screened regularly. But for the remainder, 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 that will soon swell our population. It's not an easy calculation to make, but one that make sense for the whole patient. Dr. Otis Brawley said, "Many doctors are ordering these tests purely to cover themselves. We need to think about the rational use of health care and stop talking about the rationing of health care." That 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. Why do doctors recommend routine cancer screening for elderly people? | [

Even in the same litter , both brown and black furred bears may be born. Black bears are the smallest of all American bears, ranging in length from five to six feet, weighing from three hundred to five hundred pounds. Their eyes and ears are small and their eyesight and hearing are not as good as their sense of smell. Like all bears, the black bear is timid and rarely dangerous, but if attacked, most can climb trees or cover ground at great speed. When angry or frightened, they are formidable _ . Black bears feed on leaves, roots, fruit, insects, fish, and even larger animals. One of the most interesting characteristics of bears, including the black bear, is their winter sleep. Unlike squirrels and many other woodland animals, bears do not actually sleep through the winter months. Although the bear does not eat during the winter months, sustaining itself from body fat, its temperature remains almost normal, and it breathes regularly four or five times per minute. Most black bears live alone, except during the mating season. They prefer to live in caves. Baby black bears are born in January or February after a gestation period of six to nine months, and they stay with their mother until they are fully grown or about one and a half years old. Black bears can live as long as thirty years in the wild, and even longer in some nature reserves. American black bears may have _ colours according to the passage. | [

On their way home, the wind was strong and it was getting colder and colder. Both John and Sam wanted to drink some wine to keep warm, but they had a rule. They couldn't drink any wine because they had to sell it. According to the rule, if some-body wanted to drink some wine, he had to pay the other twice the price. John was a clever man. He took out ten cents and gave it to Sam. He said, "Here is ten cents. Would you please sell me some of your wine?" Sam was a businessman , so he said, "You give me money, so of course I will sell some to you." Then he passed John a cup of wine. After drinking the wine, John felt warm soon, but Sam was still cold. Then he took out the ten cents that John just gave to him and said to John, "Here is ten cents. Please sell me some of your wine." John agreed. Sam drank some wine and also felt much warmer. But after some time, they both felt cold again, so they kept buying wine from each other with the same ten cents. Soon they drank up all of the wine.

During the test, these people were given all kinds of breakfasts, and sometimes they got no breakfast at all. Scientists wanted to see how well their bodies worked when they had different kinds of breakfasts. The rules show that if a person eats a right breakfast, he or she will work better than if he or she has no breakfast. If a student has fruit , eggs, bread and milk before going to school ,he or she will learn more quickly and listen more carefully in class. The result is opposite to what some people think. Having no breakfast will not help them lose weight. This is because they are so hungry at noon that eat too much for lunch. They will gain weight instead of losing it.

mmlu_train_23184 | In 1988, a company in Ohio invented an alcohol-based hand cleaner, which was meant to be used by health-care worker; when soap and water were unavailable. Joe Kanfer, the company's C. E. O., told me recently, "there were a couple of other alcohol products out there, but they were really ugly. Either they were greasy or they burned your hands white." Kanfer took a year and a half to develop this product which is visually appealing and does almost no harm to one's skin. Still. Kanfer lost money on it for more than a decade because people couldn't get what it was for. The product was called Purell. Today, you see it everywhere. My doctor uses it several times during every office visit. You can hear it in almost every office in the U. S. and school picnics would be impossible without it. The former president Grorge W.Bush was called a racist for using hand cleaner after first shaking hands with Barack Obama, but Bush also gave some of it to Obama and recommended it as a cold preventative . What was once barely even a product is now a growing product category, worth hundreds of millions per year. The rise of Purell makes some health professionals uneasy. Some claimed that promoting hand cleaner may worsen "our culture's irrational fear about bacteria." Still, the clear agreement among experts is that unclean hands pose a serious health risk, and are one of the main reasons in the spread of infections in hospitals. A 2007 study estimated that, in America in 2002, such infections resulted in more than a million and a half patient illnesses and caused or contributed to nearly a hundred thousand patient deaths - about double the number of U. S. deaths currently caused each year by AIDS and guns combined. However, I asked a food microbiologist whether clean hands might have a medical drawback. He said, "We might have a much healthier population if we adopted the kinds of condition that we see in many Third World countries, with poor-quality food and poor-quality water and lots of bacteria. If we did that, we would have adults who were very healthy and have very strong immune systems. Unfortunately, the price that we would pay would be extremely high child death rate.

mmlu_train_19638 | GENEVA, Feb.11 (Xinhua) --The current La Nina weather phenomenon may just be a partial cause of south prefix = st1 /China's freeze-up at the start of 2008, said the United Nations World Meteorological Organization (WMO) Monday. The latest La Nina pattern, which began in the third quarter of 2007, has picked up strength in the past three months, with sea surface temperatures now about 1. 5 to 2 degrees Celsius colder than average over large parts of the eastern and central equatorial Pacific Ocean, said the latest report issued by the WMO. Presenting the Geneva-based body's report, Rupa Kumar Killi, a WMO climate expert, said the recent month-long snow and ice-storms in China's central, southern and eastern regions could be connected with the La Nina phenomenon, the climatic opposite of El Nino . However, he said China's freeze-up was a result of several causes combined and was partly caused by a cold surge from the north and west. He also said the present La Nina cycle may last at least until mid-2008 and it is also possible, if less likely, that the cycle could stretch into the third quarter. La Nina is a large pool of unusually cold water in the equatorial Pacific that develops every few years and influences global weather. It is the climatic opposite of El Nino, a warming of the Pacific, and both have been associated with extreme weather around the globe. Since Jan. 10, snow, sleet and low temperatures have swept China's southern regions, a rare occurrence for the area. When did the latest La Nina weather phenomenon begin? | [

mmlu_train_55148 | Patients and doctors alike have long believed in the healing power of humor.It is claimed that humor not only affects patients' moods, but can actually help them recover faster. Several studies seem to support this.Patients in better spirits are known to have higher immune cell counts.Some have even claimed to have healed themselves of serious illnesses by reading comics and watching comedies. Despite all this, many researchers are not convinced.They point out the fact that many sufferings have been known to disappear naturally, with or without a daily dose of laughter.They also say that while optimism in general does seem to be related to better health, it is hard to tell which comes first. Humor in times of stress, however, clearly makes us feel better.On one level, it takes our minds off our troubles and relaxes us.On another, it releases powerful endorphins, a chemical produced by your body that reduces pain. There are cases where the appreciation of a good joke is indeed directly related to a person's health.It can show, for example, whether a person has suffered damage to one particular area of the brain: the right frontal lobe . Scientists confirmed this by having people read jokes and asking them to choose the funniest endings from a list.Subjects with normal brains usually chose endings that were based on a relatively complex synthesis of ideas.Subjects with specifically located brain damage, however, responded only to slapstick endings, which did not depend on a particular context.When pressed, the brain-damaged subjects saw the logic in the correct endings.They simply did not find them funny. Of course, humor is largely an individual matter.Next time your friend does not get one of your jokes, there is no need to accuse him of being a lamebrain.However, you might suggest that he lighten up--for the health of it.

According to the survey by China Youth Daily and www.qq.com, almost the entire nation hopes to catch images of the event at some point, with 99 percent of the 10358 respondents saying they expected to witness the satellite launch and 68.9 percent said they were certain to watch the live broadcast of the launch. On www.qq.com and www.sina.com, two popular web portals in the country, internet users have contributed some 2,000 poems and 5000 drawings on the theme of Chang'e I. "The satellite launch means much more than just saying 'hello' to the moon. Maybe in the future we could also send some people to accompany sister 'Chang'e'," said a college student in the survey. Remarkably, many people expect to visit the moon one day, with 93.4 percent of respondents saying they expected to do so. Chang'e I is named after Chang'e, a famous character from Chinese mythology. She ascended from earth to live on the moon as a celestial being after drinking an elixir. There is also another connection between the moon and China. In the 1970s, a crater on the moon was named after a Chinese stargazer, Wan Hu, who is said to be the first astronaut in human history. Legend says about 600 years ago, around the middle of the Ming Dynasty, Wan Hu, a local government official, tried to fly into space with the help of a chair, two big kites and 47 self-made gunpowder-filled rockets.

That's how thousands of people start their day at Laughter Clubs around the world - and many doctors now think that having a good laugh might be one of the best ways to stay healthy. The first Laughter Club was started in Mumbai, India, in 1995 by Dr Madan Kataria. "Young children laugh about 300 times a day. Adults laugh between 7 and 15 times a day," says Dr Kataria. "Everyone's naturally good at laughing - it's the universal language. We want people to feel happy with their lives." There are now more than 500 Laughter Clubs in India and over 1,300 worldwide. Many doctors are also interested in the effects of laughter on our health. According to a 5 - year study in the body. Laughter improves our health against illness by about 40%. So, what happens at a Laughter Club? I went along to my nearest club in South London to find out. I was quite nervous at the beginning of the class, to be honest - I wasn't interested in laughing with a group of strangers, and I was worried about looking stupid. Our laughter teacher told us to clap our hands and say "ho ho ho, ha ha ha," while looking at each other. However, our bodies can't tell the difference between fake laughter and real laughter, so they still produce the same healthy effects. Surprisingly, it works! After ten minutes everybody in the room was laughing for real - and some people just couldn't stop! At the end of the class I was surprised by how relaxed and comfortable I felt. So if you're under stress, then start laughing. You might be very pleased with the results! Which of the following is true according to the passage? | [

St. Michaels University School student Ann Makosinski was the only Canadian among the four winners at Google's annual international science fair, beating out thousands of other young scientists from around the world. Winning the international contest was "a total shock", Ann said from San Francisco. "I definitely think it will have an influence on my future." Ann thanked her family for encouraging her interest in science, telling the judges that her first toy was a box of transistors . Ann's prize includes a $25,000 scholarship and a "once-in-a-lifetime experience" from either the European Organization for Nuclear Research, Lego or Google for her Hollow Flashlight, which has no moving parts or batteries. Ann created the flashlight for a local science fair. The inspiration for the invention came from seeing unwanted batteries and after visits to the Philippines, where she saw the need for a battery-free flashlight. A friend at school there failed in her studies because of a lack of electricity and light to study when it became dark. In her project, Ann wrote that she "made two flashlights that do not use any batteries, harmful chemicals, or kinetic energy . They do not create any noise and will always work. The flashlight's only limitation is its need for at least a 5degC temperature difference to provide usable light." A You Tube video of Ann explaining how she created the flashlight has been viewed more than 1.4 million times. Despite her success, the private school student is undecided about her career path. Ann hopes she can find a way to combine her love of film with science. The four winners were chosen from 15 finalists from eight countries. The contest attracted thousands of entries from students in 120 countries. According to the passage, Hollow Flashlight _ . | [
