mmlu_train_48610 | Rescue workers and volunteers in prefix = st1 /Floridaworked non-stop to help as many dolphins as they could to return to deep water. Some dolphins made it. About 24 died. For 35 dolphins in danger there was only one chance for survival--to be sent to the Marine Mammals Care Centre. The dolphins were placed in a water pool where they have been given care _ by hundreds of volunteers who signed up for four-hour shifts . By the second week in April, only 11 of the original 35 were still alive. Each year thousands of dolphins, the lovely marine mammals, are found beached or stranded along coastlines around the world. They can't get back to the sea and will die if they don't get help, according to the Whale and Dolphin Conservation Society's website. Nobody knows what caused the dolphins to strand themselves, but the US Navy and marine wildlife experts are investigating whether the dolphin stranding was caused by sonar exercises of ships. And some scientists suggest disease, or human interference . The reason for stranding isn't completely understood. In the pool, volunteers hold the dolphins and keep their blowholes out of the water so they can breathe. A vet injects the mammals with vitamin E to help with muscle cramping . Unable to eat on their own, they are fitted with a feeding tube to get them the needed nutrition. "Today we made the first steps in getting them to eat dead fish and to eat them out of our hands," Banick said. It's a race against time and feeding times must be strictly kept to.

mmlu_train_18851 | Imagine you're at a party full of strangers. You're nervous. Who are these people? How do you start a conversation? Fortunately, you've got a thing that sends out energy at tiny chips in everyone's name tag . The chips send back name, job, hobbies, and the time available for meeting-whatever. Making new friends becomes simple. This hasn't quite happened in real life. But the world is already experiencing a revolution using RFID technology. An RFID tag with a tiny chip can be fixed in a product, under your pet's skin, even under your own skin. Passive RFID tags have no energy source-batteries because they do not need it. The energy comes from the reader, a scanning device ,that sends out energy (for example, radio waves)that starts up the tag immediately. Such a tag carries information specific to that object, and the data can be updated. Already, RFID technology is used for recognizing each car or truck on the road and it might appear in your passport. Doctors can put a tiny chip under the skin that will help locate and obtain a patient's medical records. At a nightclub in Paris or in New York the same chip gets you into the VIP (very important person) section and pays for the bill with the wave of an arm. Take a step back: 10 or 12 years ago, you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The concept was that computer chips could be put everywhere and send information in a smart network that would make ordinary life simpler. RFID tags are a small part of this phenomenon. "The world is going to be a loosely coupled set of individual small devices, connected wirelessly," predicts Dr.J.Reich. Human right supporters are nervous about the possibilities of such technology. It goes too far tracking school kids through RFID tags, they say. We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it. And how many beers accompanied by how many biscuits. When Marconi invented radio, he thought it would be used for ship-to-shore communication. Not for pop music. Who knows how RFID and related technologies will be used in the future. Here's a wild guess: Not for buying milk. Passive RFID tags chiefly consist of _ . | [

mmlu_train_53734 | It's 4 am, and Danilo C. Dequina is already awake. Holding a flashlight and a bucket, he is walking in the pre-dawn darkness along the shore of Old Poblacion Beach in the town of Maitum, Sarangani, in the far south of the Philippines. A few minutes later, he spots a patch of sand that appears to have been disturbed by a turtle. Dequina studies the area carefully, figuring out where the eggs have been buried, and then starts digging slowly. After clearing away several centimeters of sand, he uncovers a large group of eggs, roughly the size of ping-pong balls. He picks them up and puts them in the bucket. Dequina carries the eggs to his hatchery , some 50 meters away from the seashore. The hatchery is really just a sandy patch of land under the coconut trees enclosed by a black fence. It is here that he buries the turtle eggs he has collected. Today, Dequina scoops a hole, puts the eggs in it, and covers them with sand. After 45 to 70 days, the eggs will hatch. Dequina will then carry the hatchlings to the shore, and release them into the sea. He admits to feeling sorrow as he sets the hatchlings free -- most are hunted down by natural predators, and just one percent survive to adulthood. According to the Philippine Department of Environment and Natural Resources (DENR), eight species of sea turtles face extinction, including four that come to the shores of Sarangani to lay their eggs -- the Hawksbill, Olive Ridley, Loggerhead and Green Turtles. After learning about their plight , Dequina attended a DENR training session on turtle conservation and decided to take action. He helped the local government to set up the Pawikan Nesting Sanctuary next to his house in 2003. The hatchery drew the attention of the locals. "They started to change their attitudes towards sea turtles," 52-year-old Dequina says. "If they see turtle eggs, they will either bring them to me or inform me of the nesting places." Over the past ten years, more than 3,000 hatchlings have been released to the ocean. What is the attitude of local people toward Dequina's efforts? | [

mmlu_train_9417 | Every year, millions of Americans see their personal information leak into the wrong hands. Maybe there's spyware on the their computer, or a service they use suffered a security reach, leaving customers at the risk of exposure. Or perhaps their password is easy to guess. Don't fear: You can easily set up proper defenses. Here's how. * Clean Your Computer and Smartphone Before you put new security measures into place, make sure your devices are as spotless as possible. This means installing a good antivirus program and taking the time to clear out any spy -- or malware that may have already infected your system. These days, it's also worth it to make sure your phone is safe from viruses. Iphones are less likely to be targeted by spyware, but Android users should download the Lookout app to scan their devices and ensure everything is as it should be. * Secure Your WiFi. It's fairly easy for potential criminals to gain access to your information if they're able to share your connection -- that's why you want to be careful when using public WiFi. Even though you put security measures into place a couple of years ago, it's a good idea to refresh your settings. * Use passwords What you've heard is true: Passwords should use a variety of special characters, numerals, letters, and cases when possible. * Check the shopping security Take care when shopping online. Always check the security symbols when using an online site for shopping. If the lock icon encryption is not there, do not give out credit details. Also, check that the site is legal -- never go to a site from a random email and start shopping online. Keep a separate credit card just for online shopping. This will make it easier to cancel if something bad does happen and your other credit card for "in real life" can still be used uninfluenced. Don't store information on any store's website. It may be convenient but it's also a possible loss to you if the site is hacked. According to the passage, the risk of exposing personal information may possibly be caused by _ . | [

mmlu_train_44221 | Online Degrees Today, you can earn a degree from a major university without ever having sat in one of their classrooms. Many colleges and universities are offering online courses and degree programs now. Online Learning Programs With a computer and an Internet connection, you can earn a degree from home, work, or anywhere else for that matter. Online degree programs follow much the same routines as traditional learning, with a few twists. There are lectures, but they won't be in person. There are assignments , but you won't hand them to your instructor. In most situations, you are free to "go to class" when it fits your"schedule. If you get a phone call during class, you don't have to miss anything. If you get sick, you don't have to ask for someone's notes, and you just visit the lecture later. You'll communicate with your instructor by e-mail, chat room and instant messaging. Your classroom will live in a special software program. Contrary to popular belief, you will have close contact with other students and the instructor. Evaluating the Program There are a lot of questions to ask before you make your selection, such as: How do students interact with each other? Online programs can use chat rooms, instant messaging, teleconferencing, and video conferencing to communicate. The key is to find a program that has this interaction built into it and even requires it. What kind of reputation does the school have? It may seem simple-a good school will have a good online program. This reputation,however, may not be as straightforward as you think. It's not uncommon for a great school to have a weak program or two. So you'd better look at the overall quality of the school and make a judgment.

mmlu_train_40639 | 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." According to the text, a potential danger of blood transfusion is that _ . | [

mmlu_train_31713 | It took 100 years, but finally, scientists proved Albert Einstein's theory that gravitational waves exist. The waves were predicted as part of Einstein's general theory of relativity nearly 100 years ago. It was the theory of the physics behind the workings of our world and the universe. The idea was that the waves are like ripples in space, caused by some of the violent and energetic processes in the universe. For example, two black holes crashing into each other. Now a group of scientists, including ones from Caltech, MIT and the LIGO Scientific, Collaboration finally found the gravitational waves. David Reitze is the executive director of the LIGO observatory at Caltech. "We have detected gravitational waves. We did it!" What are these gravitational waves? Well, imagine throwing a rock into a pond. When the rock hits the flat surface of the water, it creates ripples or waves. Space-time is like the surface of the water. So that means gravitational waves are like the ripples moving out from where the rock hits the water. It might be hard to understand, but those gravitational waves expand and contract space and time as they move through space. And when they get to the Earth, the waves pass through, and they contract and expand the planet as the waves go by. It was Einstein who said these gravitational waves should be observable. But these are not huge waves. They are very, very small, which is why it took so long to find them. You cannot see them with your eyes. They are smaller than the size of an atom. How did the scientists find them? They used a giant scientific tool called LIGO, which stands for the Laser Interferometer Gravitational-Wave Observatory. The billion-dollar LIGO project is two L-shaped observatories. One is in Louisiana and the other in Washington state. For years, scientists have been watching two black holes in another faraway galaxy. The two were spinning around each other, moving closer and closer together. When they finally crashed into each other, it was with such power and force that gravitational waves rang throughout the universe, like a giant bell. Those waves, traveling at the speed of light, finally reached the Earth, some l. 3 billion years later. They are the same waves that the scientists announced this past week. So, what does this discovery mean? Our understanding of the heavens changed dramatically. With the discovery of gravitational waves, we'll _ . | [

mmlu_train_63212 | Meat and vegetables are measured in grams and kilograms. Milk and other liquid foods are measured in liters or milliliters. These units only measure quantity: they do not measure the value of the food to the body. The unit which measures the quality or value of food is the calorie the amount of heat given off by food when it brurns. This measurement tells how much energy a certain food has when it is completely used by the body. Our bodies use varying amount of calories. The more exercise we take, the more calories we burn. If we eat food which contains more calories than we use up, then it is possible that we would increase in weight.

mmlu_train_26022 | 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 ' .' " Narayana Hrudayalayastarted a micro-insurance to _ . | [

But this 19-year-old Swede is anything but ordinary, from the computer in his parents' home he helps the US Federal Bureau of Investigation (FBI) find out the world's most wanted cyber criminals . Jonathan first made headlines when he and another Swede, Fredrik Bjoerck, found out the maker of the "Melissa" virus in March 1999. He came to the aid of the FBI again on May 7, finding out the suspected sender of the dangerous "I LOVE YOU" virus. The suspect was caught in Manila on May 8. Jonathan's special skills are in hot demand as officials around the world express alarm at the "virtual" crimewave. In between studying for final exams, hanging out with friends and refereeing his younger brother's football matches, the quiet, gentle teenager also gives lessons on e-security to large companies. He reads a lot and exchanges information with other computer experts to know much about the latest tricks of the hacker trade. Many companies have already tried to employ him, but he is not interested at the moment. Instead, he plans to begin law school in the autumn at Sweden's Uppsala University and start up his own e-security company. Although he works with the FBI now, his family insists he's just "a regular kid". "Jonathan is a great kid, he has his friends and he does a lot more than just play with the computer," his little sister Tessa said, adding that he helps the FBI because "he likes to help", not because he's looking for fame and recognition. When the world was hit by the "Love Bug" virus, Jonathan was too busy preparing a speech on e-security to look into the problem. "Finally on May 7, I had some free time, so I began looking." Within a few hours, he had found the suspect and e-mailed his method and results to the FBI.

mmlu_train_42936 | Of all the animals in the animal kingdom, which one (aside from man) is the cleverest? There are several ways of measuring the intelligence of animals. In one test a scientist sets three same cans on a table. While the animal watches, he puts food under one of the cans. Then he leads the animal away. Some time later, he brings it back to see if it remembers which can has the food. No smelling is allowed; the animal must go directly to the correct can or it fails. This is called a delayed-response test. The idea is to find out how long an animal's memory can keep information. The scientists would try showing the cans to the animal one hour later, or two hours later, or even a full day later. They discovered that chimpanzees and elephants have the best memory, and were able to remember the correct can for at least twenty hours. No other animal is close. Dogs came next, but they only remember for nine hours. To settle the matter, the scientists designed a huge maze and ran the chimps and elephants through it. The maze was very difficult, with many blind paths and dead ends. It took the chimps ten minutes to find their way out. The elephants needed half an hour. Even allowing for the elephants' slower rate of speed, the test shows that chimpanzees are the cleverest animals. From this and other tests, the scientists drew the following conclusion: an animal's intelligence depends on the size of its brain in proportion to the size of its body. The elephant's brain weighs ten pounds. But this is only 1/600th of its 6,000 pounds body. A chimp's brain weighs about one pound, or 1/120th of its total body weight. So in proportion to its body size, the chimp has four times as much brain as the elephant----more brain for less body. The chimp is the champ! The passage tells that elephants _ . | [

Studies show that people who perform kind acts are more relaxed, happier, and healthier than other people. In one study at Arizona State University researchers, found that many volunteers experienced a sudden feeling of joy, followed by a long period of calm, after performing a kind act. This feeling, called "a help's high" may actually help reduce stress as the body releases naturally painkillers. Stress can cause' serious health problems, and heart depression, and .sleeping problems. However, the study found that volunteers had fewer *stress-related health problems when they did helpful things for other people. The study also found that people who did nice things for others felt better about themselves as well. They had higher self-esteem , and were' happier. Many believe this is because volunteers spend more of their time with other people. People who are more outgoing are often healthier. Another study at the University of Michigan's Survey Research Center confirmed the health benefits of volunteering. A ten-year study showed that people who volunteered live longer than those who didn't. Although you shouldn't need a reason to be helpful, it is nice to know that kindness may help you live longer.

mmlu_train_21962 | It is not just humans that get stuck in their ways. Scientists have discovered that old bees have trouble finding their way to new hives as their learning behavior becomes increasingly inflexible. Bees are typically impressive navigators, able to wind their way home through complex landscapes after visits to flowers far removed from their nests. But researchers from Arizona State University and the Norwegian University of Life Sciences found that aging damages the bees' ability to extinguish the memory of an unsuitable nest site even after the group has settled in a new home. To test how old bees adapt to a changed home location, researchers trained bees to a new nest box while their former nest was closed off. Groups composed of mature and old bees were given several days in which to learn the new home location and to extinguish the bees' memory of their unusable former nest box. The scientists then tore down the bees' new home and forced groups of mixed-age bees to choose between three alternative nest locations, including the former nest box. Old bees began flying toward the former nest site, despite the experience that should have told them that it was unusable. "Although many old bees fail in learning tasks, we also discovered that a few still perform with excellence," explains Daniel Minch, lead author of the study and a senior life sciences researcher in Norway. The scientists believe that their findings with bees offer a new means to model and understand the variability found in brain function between individuals, where some individuals' memories remain complete, while others' learning behavior becomes inflexible with age.

The social media giant has never denied that it's keeping track of conversations you have near your phone ( if the Facebook app is open , that is ) , but not , one expert has told NBC that Mark Zuckerberg's empire may be keeping ears on you at a more regular basis . According to Professor Kelli Burns , who teaches mass communication at the University of South Florida , it may be listening more often than it lets on . To prove her point , Burns turned on the microphone feature on her phone , and said , " I'm really interested in going on an African journey . I think it'd be wonderful to ride in one of those jeeps . " Less than a minute later , when she checked her Facebook page , she was met by a story about a journey - the first post on her newsfeed . There was also a car ad on her page . While Facebook says that it's only keeping its ears open to help " identify the music you're listening to and TV matches you're watching , " Burns' little experiment suggests that there may be other motivations at play as well . But the social media company has denied claims that it records any conversations , and told The Independent , " Facebook does not use microphone audio to inform advertising or News Feed stories in any way . Businesses are able to serve related ads based on people's interests and other statistic information , but not through audio collection . " Whether you believe this statement or not , there are ways to stop Facebook from listening in at all . Simply turn off your phone's microphone by heading over into Settings ( if you're an iPhone user ) , going to the Privacy tab , then clicking on Microphone . From there , you can remove Facebook's mic privileges , and probably , stop the company from hearing your conversations . On Android , you can also go to Privacy under the Settings tab , and change Facebook's permissions .

Children aged between three and seven should watch no more than 30 minutes to an hour of TV a day; 7 to 12-year-olds should be limited to an hour,and 12 to 15-year-olds should watch one and a half hours at most. Both adults and children believe that it can be difficult to cut down on screen time."It needs a bit of effort,but small steps can make a difference,"says Dr. Aric Sigman.He also offered some tips to change the family's TV habits. TVs and computers should be placed out of children's bedrooms.Watching TV before going to sleep doesn't help children to settle . Having the TV and computer in a family room also means that parents can know what they are watching and who they are talking to online.Parents can tell children how much time they can spend watching TV or playing computer games.Parents can tell children to do something different,such as playing games or going out for a bike ride.Dr. Aric Sigman says:"We went into lots of schools and the children told us they wished their parents would take them to the park and play with them."

mmlu_train_54337 | British researchers have found that children's IQ predicts their probability of becoming vegetarians as young adults. Recent studies suggest that vegetarianism may be associated with lower cholesterol , reduced risk of overweight and heart disease. "We know from other studies that brighter children tend to behave in a healthier fashion as adults--they're less likely to smoke, less likely to be overweight,less likely to have high blood pressure and more likely to take exercise." lead author Catharine Gale said, "This study provides further evidence that people with a high IQ tend to have a healthier lifestyle." In the study, Gale's team collected data on nearly 8,200 men and women aged 30, whose IQ had been tested when they were 10 years of age. "Children who scored higher on IQ tests at age 10 were more likely than those who got lower scores to report that they were vegetarian at the age of 30."Gale said. The researchers found that 4.5 percent of participants were vegetarians. Of these, 2.5 percent were _ , and 33.6 percent said they were vegetarian but also ate fish or chicken. There was no difference in IQ score between strict vegetarians and those who said they were vegetarian but also ate fish or chicken,the researchers added. One expert said the findings weren't the whole answer,however. "We don't know the beliefs or attitudes of the parents of the children,nor do we know if there was a particular event that led these children to becoming vegetarian in their teens or adulthood." said Lona Sandon, and assistant professor at the University of Texas Southwestern Medical Center at Dallas.

mmlu_train_53492 | Most people think zoos are safe for animals, where struggles such as difficulty in finding food and avoiding natural enemies don't exist. Without such problems, animals in zoos should live to an old age. But that may not be true for the largest land animals on earth. Scientists have known that elephants in zoos often suffer from poor health. They develop diseases and behaviour changes. Sometimes, they even become infertile, or unable to have babies. To learn more about how elephants are affected, a team of international scientists compared the life spans of elephants born in zoos with those living outdoors in their native lands. Zoos keep detailed records of all the animals, such as birth dates, illnesses, weight and death. These records made it possible for the researchers to analyse 40 years of data on 800 African and Asian elephants in zoos across Europe. The team found that female African elephants born in zoos lived an average of 16.9 years while those in the wild lived an average of 56 years. Scientists don't yet know why wild elephants seem to be so much better than their zooraised elephants. Georgia Mason, a biologist who led the study, thinks stress and obesity may be to blame. Zoo elephants don't get the same kind of exercise they would in the wild, and most are fat. Another finding from the study showed that Asian elephants born in zoos were more likely to die early than Asian elephants caught in the wild and brought to zoos. Mason suggests stress in the mothers in zoos might cause them to have babies that are less likely to survive. In order to let the elephants in the zoos live longer, people should _ . | [

Of course you don't want to spend your holiday sick in bed. So what can you do to stay in good health? There are three things you should remember when you travel: relax, sleep, and eat well. A holiday must be a time for relaxing. But very often it is not. Think about what you do when you are a traveller. There are many places to visit: museums, shops, parks, churches. You may spend most days walking around these places. This can be very tiring. You may have a terrible headache after a few hours. If this is the way you feel, you should take a rest. Don't ask your body to do too much. A tired body means a weak body. And a weak body gets sick easily. So sit down for a few hours in a nice place. In good weather, look for a quiet park bench . Or you can stop at a cafe. You can learn a lot by watching people while you rest. Sleep is also important. If you want to stay healthy, you need to get enough sleep. You may have trouble sleeping at night when you travel. There may be too many noises in your hotel or the bed may be uncomfortable. If this is true, don't be afraid to change rooms or hotels. Or you may get enough sleep for another reason. You may want to stay out late at night. In many cities, the nightlife can be very exciting. Then you should plan to sleep for an hour during the day. The extra hour can make a big difference. Finally, if you want to stay healthy, you must eat the right kinds of foods but you need to be careful about how much you eat. Lots of food is not good for you. So, remember this, if you want to enjoy your holiday, take care of yourself. Give your body some rest. Get enough sleep and eat good, healthy food.

But what motivated me to get serious about it was turning 30. I weighed 414 pounds. I was always tired. Some of my family members have suffered from heart disease,and I was scared. I also wanted to look better. So after my birthday,I walked into the office of a weightloss doctor. She was very understanding. Her focus was on balanced meals and she wanted me to exercise. Walking was all I could do at first. I started by walking a few blocks and gradually increased the distance,until one weekend,I found myself saying,"Wow,this seems pretty easy." So I started to run. I was losing nine or ten pounds a month,and I had more energy. I started to think about the New York City Marathon. For years,I watched the runners and thought,"This looks like fun,but I could never do that." But now I realized that maybe I could. I joined the New York Road Runners. I ran a 10km,then a halfmarathon. I still wasn't confident I could run a full 26 miles. But I told myself I was going to do it,no matter what. By my 33rd birthday,I was down to 180 pounds. I started formally training for the marathon. And on the morning of November 1,I stood on the Verrazano Bridge in Staten Island with more than 40,000 other runners,waiting for the event to start. It was unbelievable to have the audience cheering me on,handing me cups of water. And I crossed the finish line. My friends sprayed (......) me with beer,as if I'd won the Super Bowl.

mmlu_train_33933 | Health officials issued a waring over common energy-saving lghtbulbs after research showed some types could potentially harm the skin and may even raise the risk of cancer. A study by the Health Protection Agency (HPA) found that some eco-friendly lightbuulbs release levels of ultraviolet (UV) radiation that are above recognized safety limits. The agency urged people who work with lamps nearby to avoid spending more than one hour within a foot of the eco-friendly bulbs. The warning was directed at those using desk lamps for long periods, such as jewellery makers, and others who might have lights close to their faces, such as car mechanics. John O'Hagan, a scientist at the HPA's centre for radiation, chemical and environmental dangers, began tests on the ligthbulbs after patient groups raised concern about them. Among the groups were patients with a skin disease called lupus, which makes people highly sensitive to light. The tests measured UV light from the lamps and found the highest levels of UV radiation, measured 2cm from the lightbulbs, were _ to being outside in direct sunlight in the summer. The most immediate risk from the lightbulbs is a reddening of the skin similar to sunburn, but there is also a small increased risk of skin cancer associated with this, again similar to that of sunburn. The risk of health problems from the lightbulbs was not so high that people should remove them from their homes. People are advised to avoid using open lightbulbs for long close work until the problem is sorted out. It has confirmed that the government will not be reviewing its strategy on introducing energy efficient lightbulbs. We can learn from the passage that _ . | [

Fifteen -year-old Paige suffers from a rare brain condition. The disease affects as few as 12 people in the world, and can kill her any day without warning. And her condition has _ in recent months. Each time she closes her eyes, she may never wake up. Rachael and Leigh Badman are worried that she couldn't live through Christmas. They filled their house with Christmas decorations on November1, so she could enjoy her favorite day of the year in advance. Paige was diagnosed with the condition four years ago. Mrs. Badman described the condition as "being on death row" as she never knows if she will wake up and still have a daughter. She said, " Paige always loves Christmas and it's heartbreaking to see her suffering like this." In the last months, Paige has been unable to eat and has never walked or spoken. But she loves music, and enjoys watching pop stars' DVDs. And in May she also went on holiday to Florida with her parents and little brother, Kefton. The family , who have already organized parts of Paige's funeral, also saw the teenager swimming with dolphins during the trip. Since then, however, her condition has worsened. Mrs Badman, who is separated from her husband and works as Paige's full-time carer, said, "Now she can't eat or drink anymore, and her brain is shrinking.

mmlu_train_60129 | Lots of bacteria can grow in the seemingly unfriendly environment under glaciers , a region formerly considered free of much biology. This finding by glaciologists working in Switzerland could help solve some puzzles of the last ice age and point the way for finding life on other planets. Bacteria with odd lifestyles have been under increasing study lately, with most research focused on the species which prefer hot homes. The new study shifts attention to the other end of the thermometer . The exciting thing is the idea of pushing the window of acceptable bacterial environments a little bit farther open. Researchers have previously collected small numbers of bacteria from ice in Antarctica and Greenland, but they could not determine whether these were active bacteria or just frozen cells blown in by wind. In contrast, the earth beneath two Swiss glaciers harbors large colonies of bacteria--hundreds of millions of cells per gram--that appear to be growing at 0degC. Scientists followed upon these findings by taking samples of ice, water, and earth at two mountain glaciers. They found that earth beneath the glaciers contained much larger populations of bacteria than did surface and inner part of ice. Those findings indicate that the bacteria were growing at the bottom of the glacier and are not something washed in while the scientists drilled through the ice. Looking at the bacteria under a microscope , the researchers found that many were in the process of dividing, and healthy under the ice. The bacteria might break down minerals and plant remains originally buried beneath the glacier or later washed in by water going slowly through the ice, scientists say. "Some of the assumptions we have made in the past now must be seriously questioned," say researchers. "If bacteria can live under glaciers on Earth, why not on other planets? The new study points out in many ways that the bottoms of glaciers are probably quite good environments from the point of view of bacteria. So, maybe the bottom of the ice sheets on other planets would be a sensible place to try if you're going to look for life on them."

mmlu_train_83424 | If you don't keep yourself warm enough, winter can be a time of illness. During the winter months, people easily get colds and flu . Many think they are the same, but these two illnesses are different. Colds can stay with you for up to a week. You will have a running nose, sore throat, headache, cough and a fever. Flu is more serious. You will feel sick very quickly. You will have a fever and a headache. Your body will hurt and become weak. This could last for up to four weeks. Is there any way to keep yourself away from colds and flu? Staying clear of people with colds or flu may work. Try not to touch your nose or eyes if you have been close to someone who has a cold. Wash your hands, especially after cleaning your nose. Going out with wet hair can also give you a cold! If you catch a cold or flu, go to bed and rest. Doing this will help you get better. Drink lots of water. Stay in a warm, well-aired room. If you have a headache, or your muscles hurt, take some medicine. In _ , people get colds and flu easily. | [

mmlu_train_32249 | Caffeine not only gives us a daily jump start, but new research suggests it also can strengthen long-term memory. According to the US Food and Drug Administration, nearly 90 percent of people worldwide consume about 200 milligrams of caffeine each day. That' s equivalent to about one strong cup of coffee a day. Writing in " Nature Neuroscience" , Johns Hopkins University researchers say their findings show that caffeine strengthens certain memories for up t0 24 hours after being taken in. " We've always known that caffeine has cognitive-enhancing effects , but its ,particular effects on strengthening memories and making them resistant to forgetting has never been examined in detail in humans, " said senior author of the paper Michael Yassa. " We re- port for the first time a specific effect of caffeine on reducing forgetting over 24 hours. " Conducting a double-blind trial, the researchers worked with a test group of people who didn't regularly consume caffeinated products. Five minutes after studying a series of images, the test subjects were given either a placebo or a 200-milligram caffeine tablet. To check the caffeine levels of their test subjects, the research team took saliva samples from them before they took their tablets and again one, three and 24 hours after- wards. Both groups of test participants ( those who took the placebo and those who took the caffeine tablet) were tested the following day to see if they could recognize the images they' d seen the previous day. The test included showing the test subjects another series of images that included some new images , those that were shown the previous day, as well as other images that were similar, but not the same as those they had viewed earlier. The researchers found that more members of the group who were given the caffeine tablets were able to correctly identify some of the new images as " similar" to previously viewed images rather than incorrectly identifying them as the same. "We also know that caffeine is associated with health and longevity and may havesome protective effects from cognitive decline like Alzheimer' s disease . " said Yassa.

mmlu_train_58673 | Beijing--(13, July) China sent up a new data relay satellite , Tianlian I-02, on Monday at the Xichang Satellite Launch Centre in South-western Sichuan province.The new satellite will promote the country's satellite communication network for space docking . The satellite was launched on a Long-March-3C carrier rocket at 11:41 p.m., sources at the centre told Xinhua News Agency.The satellite separated from the rocket 26 minutes after its launch and was then successfully delivered into a geostationary transfer orbit . Developed by the China Academy of Space Technology under the China Aerospace Science and Technology Corporation, the satellite is the country's second data relay satellite.The first, Tianlian I-01, was launched on April 25.2008. The two satellites will form a network to improve communications between China's spacecraft and bases on Earth, according to the centre.They will also be used to help the nation's first space docking, scheduled for the second half of this year. As planned, China will launch space module Tiangong-I, which was designed as a platform that will dock with an unmanned spaceship, Shenzhou, for the county's first space-docking mission this year. Two more Shenzhou spaceships will dock with Tiangong-I next year, and one will be manned by two or three astronauts, according to China Manned Space Engineering Office, which was the main user of the Tianlian I series data relay satellites. "The new satellite can cover a greater area to track and command the country's space vehicles in low-Earth orbits, such as manned spacecraft and remote sensing satellites, from a higher position in outer space.Only three satellites of this kind are needed to form a global communication network, and China has two now." Pang Zhihao, a researcher and deputy editor-in-chief of Space International, said. The satellite could also equip astronauts with real-time communications, which will benefit the country's future manned space flights, he said. The best title of the passage could be _ . | [

mmlu_train_26159 | It looks like a scene from the thriller movieJaws,but these photos of a huge shark swimming with swimmers were in fact taken in Britain. The amazing pictures,which showed that the basking shark was swimming friendly with swimmers,were taken at Porthcurno beach,Cornwall,where the basking shark was swimming just yards off shore. The single 14foot giant was feeding in the shallow waters off the scenic area,and quickly became curious about the swimmers and surfers sharing the water. Though it came within touching distance,the swimmers and surfers were in no danger. The large sharks are plankton feeders-unlike the man-eating Great White fromJaws. Beach-goer Rachel Hosken,who took the pictures,said that several basking sharks had been seen in the area."It is one of the few I have ever seen around this year and it was great to see," she said excitedly."There are usually more of them by now,but for some reason there are fewer around than normal at this time of year. I think more have been spotted in deeper waters,but the particular one in the pictures seems to have taken a liking to this spot. I have seen it a few times." Known as the gentle giant of the sea,the basking shark is the second largest fish in the sea,only weighing lighter than the whale shark. They can grow to over 36 feet (11 meters) and weigh up to seven tons (7,000 kilograms) and feed on a diet of plankton and small fish. Basking sharks normally begin to appear in May and June.

mmlu_train_38704 | After almost 30 years of arguing that a black hole swallows up everything that falls into it, British astrophysicist Stephen Hawking moved backward last week. The world-famous writer of "Brief History of Time" said he and other scientists had got it wrong. "I've been thinking about this problem for the last 30 years, and I think I now have the answer to it," said Hawking. "A black hole only appears to form but later opens up and set free information about what fell inside. So we can be sure of the past and can predict the future." The findings could help solve the "black hole information paradox ", an important puzzle in modern physics. A black hole is an area in space where matter is under such pressure that even light can not escape from its gravitational pull . But, exactly what happens there has long puzzled scientists. Black holes occur when a powerful star burns up its nuclear fuel and gravity forces it to break down in on itself. The great weight of the star's outer layers moves in towards its center. The force of gravity keeps nearly all light from escaping and nothing inside can be seen from the outside. The star actually disappears from the universe into a point of infinite density . That is a place where the laws of general relativity that govern space and time break down. Hawking has devoted most of his life to studying these questions. At the beginning, _ believed the holes were like a "universal vacuum cleaner", sucking up everything in their path. Hawking revolutionized the study of black holes when he proved, in 1976 that, under the strange rules of quantum physics , when black holes form they send out energy and lose mass in the process. In thinking up this so-called "Hawking radiation", the prefix = st1 /Cambridgemathematician also created one of the biggest puzzles in physics. These particles , he said, contained no information about what has been occurring inside the black hole, or how it formed. Under his theory, once the black hole disappears, all the information within it is lost. What's the importance of Hawking's new findings? | [

mmlu_train_7083 | The oil from palms has a wide variety of uses and is found in food, soaps and shampoos. An international team found a gene that made some of the trees produce more oil than others. Dr Rajinder Singh, from government agency the Malaysian Palm Oil Board, said, "The oil palm has three fruit forms: a thick-shelled type --the Dura; those that don't have any shell--the Pisifera; a third form produced as a cross between the thick shell and the one without the shell--the Tenera, which are more of the fleshy fruit to produce the oil," and the researchers identified the gene producing this trait. While oil palm growers attempt to grow only the thin-shelled Tenera variety, up to 10% of the seeds can be contaminated , and turn out to be the other less oily plants. Prof. Martienssen, from the Cold Spring Harbour Laboratory, said, "We can now use that gene in genetic testing, which will allow growers as well as producers to know exactly what sort of tree they are planting before it produces fruit. It takes a long time for these trees to produce fruit, but by being able to predict exactly what sort of fruit that trees will produce, it will greatly assist growers." The researchers say this could offer a more sustainable form of agriculture. Prof. Martienssen said, "This finding gives us huge hope. We hope to maximize land usage and produce a lot more on the same amount of land, because we do not want to destroy the rainforest any more." However, the environmental group WWF-UK said that the global demand for oil palm was growing rapidly, making the expansion of plantations inevitable. Adam Harrison, the organization's food and agriculture policy officer, said, "In a sense it does not matter if a 'good' variety replaces forest or a 'bad' one, the wildlife and communities that need access to that land will suffer. So for palm oil to be sustainable, the process of allocating land needs to be controlled. There is an abundance of low-carbon, low-wildlife and conflict-free land available and there is no more need for forest areas to be changed." What can we infer from the passage? | [
"The plantation of oil palms has decreased in recent years.",
"The Dura produces less oil than other two types of palm fruit.",
"It takes less time to produce fruit, Pisifera, than other two types of fruit.",
"The researchers are trying to produce more palms with the fruit, Tenera."

mmlu_train_90448 | Many companies use guards and expensive alarm systems to protect their property . Soon a new kind of protection will be used--robots. Engineers have been working on the first mobile robots for businesses. The robots will guard factories, warehouses and museums at night. The mobile robots will move around slowly on wheels. They will be able to detect(,) people through walls and pick up sounds, such as breaking glass. They can be fixed with loud sirens to frighten thieves, or radios to signal police or guards. To protect a building, a robot will have to move around without knocking into the walls. Information about the building will have to be stored in the robot's small, built-in computer. A floor map could be programmed into the computer's memory, for example. A mobile robot will not be able to do everything. Unlike human guards, it will not be able to climb stairs, open doors, or move along rough ground. It won't be able to tell the difference between friends and enemies. Because of that, people will have to be prevented from entering the area it moves. One kind of mobile robot will be able to "sense" whether a chair or a box has been moved and go around it. This robot will also judge size well enough so that it won't send an alarm if a cat crosses the room. And if someone tries to steal this robot, it will sound a loud, painful siren. The three-foot-tall robot is hard to be stolen anyway. It weighs about 200 pounds. U.S. companies pay almost $10 billion a year to protect their property with alarm systems and human guards.

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! How did the writer feel at the beginning of the class? | [

mmlu_train_60776 | When I was small and my grandmother died, I couldn't understand why I had no tears. But that night when my dad tried to cheer me up, my laugh turned into crying. So it came as no surprise to learn that researchers believe crying and laughing come from the same part of the brain. Just as laughing has many health advantages, scientists are discovering that so, too, does crying. Whatever it takes for us to reduce pressure is important to our emotional health, and a study found that 85 percent of women and 73 percent of men report feeling better after crying. Besides, tears attract help from other people. Researchers agree that when we cry, people around us become kinder and friendly and they are more ready to provide support and comfort. Tears also enable us to understand our emotions better; sometimes we don't even know we' re very sad until we cry. We learn about our emotions through crying, and then we can deal with them. Just as crying can be healthy, not crying -- holding back tears of anger, pain or suffering -- can be bad for physical health, Studies have shown that too much control of emotions can lead to high blood pressure, heart problems and some other illnesses. If you have a health problem, doctors will certainly not ask you to cry. But when you feel like crying, don't fight it. It's a natural -- and healthy -- emotional response .
