mmlu_train_12986 | A micro blog with space for 140 Chinese characters had once been a source of endless amusement for Wang Ganghui, a senior majoring in biochemistry at Ji'nan University. Until last month, the 21-year-old Wang had believed that he was part of a broader movement. Recently, however, Wang's micro blog is silent. The reason? It's because of a woman known as "Zhao Meimei". Earlier this month, Wang joined many other users to criticize the US-based student for her wealthy overseas life, because they thought her money came from _ since her mother was a local official. But later Wang found out that the woman student was actually being supported by her father, a hard-working businessman. "I felt guilty... Someone hid part of the truth to make a conflict. The worst thing is - I did not even have a chance to apologize to her," he says. Wang is not the only young Internet user to be confused by an online world made up entirely of broken information. According to official statistics, the number of micro bloggers in China now exceed 300 million. For private users, a micro blog can provide real-time updates from anyone a user chooses to "follow". These can range from family members to celebrities . Information can instantly be spread through "re-tweeting". In the public area, however, a micro blog can also become a link between users and the authorities. However, with the increasing popularity of micro blogs comes a number of problems. Chen Changfeng, deputy director of the School of Journalism and Communication at Tsinghua University, stressed two major types of misbehavior that can occur on micro blogs and upset young users. "Some marketers spread fake news just to make some person or product known to more people; others use the free channel to manufacture and spread fake news and rumors like a virus," Chen says. He says that an average micro blogger receives and transmits information, but when faced with such a vast amount of information, he may lack the ability to tell the difference between the real and the fake stories. Having realized this, Internet users have come together to combat micro blog misconduct by forming voluntary groups such as the Rumor Clarification Association. The government and individual operators of micro-blogging sites have also stepped into monitor posted content. Which of the following is true? | [
"A micro blog can provide real-time updates from anyone.",

mmlu_train_13143 | This summer, Monika Lutz's life took an unusual turn. Instead of heading off to college, the high school graduate packed her bags for a Bengali jungle. Lutz, like a growing number of other young Americans, is taking a year off. Gap years are quite common in Britain and Australia, but they are just beginning to catch on in the U.S. Lutz, who grew up in Boulder, Colo., has put together a 14-month schedule that includes helping deliver solar power to some communities in India and interning for a fashion designer in Shanghai---experiences that are worlds away from the lecture halls and university dormitories that await other students. "I could not be happier," she says. Why are students attracted to the gap-year concept? According to new survey data from Karl Haigler and Rae Nelson, education-policy experts and co-authors of The Gap-Year Advantage, the most common reason for this is to avoid burnout. "I felt like I was focused on college as a means to an end," says Kelsi Morgan, an incoming Middlebury College freshman who spent last year interning for a judge in Tulsa, Okla., and teaching English at an orphanage in the Dominican Republic. The hope is that after a year out of the classroom, students will enter college more energized, focused and mature. That can be an advantage for colleges too. Robert Clagett, dean of admissions at Middlebury, did some research a few years ago and found that a single gap semester was the strongest predictor of academic success at his school. Most experts recommend securing a spot in college before taking a gap year and warn against using the time off to lengthen your resume. "Most admissions folks can see right through that," says Jim Jump, the academic dean of St. Christopher's School in Richmond, Va. But for students like Lutz, who, after getting rejected from five Ivies, decided to take time off, a gap year can help focus interests. Lutz now plans to apply mostly to non-Ivies that have strong marketing programs. "This experience has really opened my eyes to the opportunities the world has to offer," she says. But at least one education expert doesn't want schools spreading the gap-year message. In a study that followed 11,000 members of the high school class of 1992 for eight years after graduation, Stefanie DeLuca, a sociology professor at Johns Hopkins University, found that, all things being equal, those who delayed college by a year were 64% less likely to complete a bachelor's degree than those who didn't. DeLuca did not say whether these students voluntarily started college late, but at the very least, her work indicates that taking a gap year doesn't guarantee success. "I'm not going to say that time off does not have benefits," says DeLuca. "But I think we should not be so enthusiastic." The students take gap years mainly because _ . | [

It was sent towards Mars by American scientists on August 12th,2005. Its tasks are to study Mars' atmosphere and return photos to Earth. But before that "Mars Orbit Express" must travel about 100 hundred million kilometers and seven months. It reached Mars' orbit in March,2006. Mars and Earth have similar weight and size. However,Mars is closer to the sun than Earth. Mars is very cold. The average temperature is below 50degC. The temperature at noon only reaches 20degC during a Mars day. Its atmosphere is mostly CO2. It has much sand and two moons---Phobos and Deimos. Scientists think Earth and Mars had similar beginnings 4.6 billion years ago. But while Earth supports millions of lives,Mars becomes bad. "Earth easily could have turned out like that." said an scientist, "It is important for us to find out why and Mars Orbit Express' should do that." "Mars Orbit Express" also would help scientists to learn what might happen to Earth in the future. "Mars Orbit Express" would work for about four years.

Throughout the world, every night children and their elders are "talking" online-many of them are talking at the same time. It's fast: trying talking to six people once. It's convenient: three or four words per exchange. It takes cleverness, concentration and quick fingers. And it requires very simple language. There's neither time nor space for explanations. Why waste valuable time telling six friends you have to leave for a moment to take care of your little brother when BRB (be right back) will do? Want to enter a conversation? Just type PMFJI (pardon me for jumping in). Interested in whom you're talking to? Type A/S/L, the nearly universal request to know your pal's age, sex and location. You may get 15/M/NY as a reply from your pal. If something makes you laugh, say you're OTF (on the floor), or LOL (laughing out loud), or join the two into ROTFL (rolling on the floor laughing). And when it's time to get back to work or go to bed, you type GTG (got to go) or TTYL (talk to you later).

Because he had pushed his body to the limit of its strength on the trip, a chemical change began to take place inside him. The material between his bones became weak. In less than one week after his return, he could not stand. Every move that he made was painful. He was not able to sleep at night. The doctore told him that they did not know how to cure Mr. Cousins ' problem and he might never get over the illness. Mr. Cousins, however, refused to give up hope.

mmlu_train_5905 | Should universities focus on training workers for the next decade or curing diseases for the next century? A group of governors, educators, and CEOs weighed in on the best way universities can prepare for the future. They debated how the U.S. can take the responsibility for research while still preparing students for real jobs. Oklahoma Governor Mary Fallin said that the first thing she thinks about as governor is educating Oklahoma students and strengthening the workforce. So she's carrying out a program called "America Works: Education and Training for Tomorrow's Jobs" that aims to "reorganize our education system with the current needs of our employers". The state governor added that this new educational approach doesn't just benefit students and companies, but also improves the state economy. "We've been able to attract new companies to our state because of what we're doing with our universities, because our students are a pipeline for the workforce," she said. "General Electric Company (one of the world's biggest companies) is coming to Oklahoma." Other group members were more focused on the long-term goals of a research university. Amy Gutmann pointed out that "basic research is the foundation for everything else that happens at a university. And if we don't do it, nobody else will." "And if nobody does that research, we'll pay the price in health care bills," argued Vagelos, who is a former CEO of Merck & Co., Inc, one of the largest pharmaceutical companies in the world. "The jobs of universities are basic research, which is what is needed for attacks on disease," he said. "There has been a reduction in coronary heart disease by 60% in the last forty years because of this research, and that reduces health care costs." James Hunt, former North Carolina governor, argued for a happy medium. Effective communication, he said, would help the public see that the research conducted at universities actually serves a practical purpose. Eli Broad, founder of the Broad Foundations, agreed. "We have to show the public what research has achieved," he said. "We have to show how it actually goes from basic research to something they can understand."

mmlu_train_18178 | Many years ago in a small German town, a Jewish businessman had the misfortune of owing a large sum of money to the moneylender. The moneylender, who was old and ugly, fancied the businessman's beautiful daughter. So he proposed a bargain. The moneylender told them that he would put a black pebble and a white pebble into an empty bag. The girl would then have to pick one pebble from the bag. If she picked the black pebble, she would become the moneylender's wife and he would _ her father's debt. If she picked the white pebble, she need not marry him and her father's debt would still be forgiven. But if she refused to pick a pebble, her father would be thrown into jail. They were standing on a pebble-strewn path. As they talked, the moneylender bent over to pick up two pebbles. The sharp-eyed girl noticed that he had picked up two black pebbles and put them into the bag. He then asked the girl to pick a pebble from the bag. No doubt she was caught in a dilemma. What would you have done if you were the girl? Careful analysis would produce three possibilities: 1.The girl should refuse to take a pebble. 2.The girl should know that there were two black pebbles in the bag and expose the money-lender as a cheat. 3.The girl should pick a black pebble and sacrifice herself in order to save her father from his debt and imprisonment. The above story is used with the hope that it will make us appreciate the difference between lateral and logical thinking. Read on... The girl put her hand into the moneybag and drew out a pebble. Without looking at it, she fumbled and let it fall onto the pebble-strewn path where it immediately became lost among all the other pebbles. "Oh, how clumsy of me!" she said. "But never mind, if you look into the bag for the one that is left, you will be able to tell which pebble I picked." Since the remaining pebble is black, it must be assumed that she had picked the white one. And since the moneylender dared not admit his dishonesty, the girl changed what seemed an impossible situation into an extremely advantageous one. It can be inferred from the passage that _ . | [

A plate of chicken is a good meal before games because it has much energy. In fact, the best meal before games should have carbohydrates . Foods like potatoes, bread, bananas are rich in it, chicken and meat are not. Carbohydrates are the best and most easily used forms of energy. The energy that you get for today's game is from what you ate yesterday. The best time to exercise is early in the morning. Morning is a good time to exercise, but it may not be suitable for you. If an afternoon or evening period suits you, and you enjoy the feeling of getting healthier, you can choose any time to exercise. There is no fixed time for you to exercise. If you drink water when you exercise, you'll get headaches and feel tired. The fact is that you must have some water during breaks when you exercise. And after exercising, you must have enough water. If you don't drink enough water, then you'll probably get headaches and feel tired. Exercising the same body part every day is the fastest way to improve strength. False! Exercising the same body part every day is the fastest way to cause problems. To improve strength, you want to work your muscles hard, but then you need to give those muscles a day of rest. Too much exercise can cause serious problems to muscles. Girls who do strength training will make their muscles big. Wrong!

Sounds serve to please us in music. Sound has a waste product, too, in the form of noise. Noise has been called unwanted sound. Noise is growing and it may get much worse before it gets any better. In order to know how noise affects people and animals, scientists have been studying for several years. They are surprised by what they have learned. Peace and quiet are becoming harder to find.

mmlu_train_6967 | When Jeff Sparkman draws his cartoon superheroes with colored pencils, he often has to ask other people to tell him what color his masked men turned out to be because he's color-blind. Now, a new smart phone application (app) can help him figure out what colors he's using and how the picture looks to most everyone else. The DanKam app, available for iPhone and Android for $2.99, is an application that turns the vague colors that one percent of the population with color-blindness sees into the "true" colors as everyone else sees them. In America, an estimated 32 million color-blind Americans--95% are males--can soon have their life improved. "DanKam takes the stream of data coming in through the phone's camera and changes the colors slightly so they fall within the range that people who are color-blind see,"developer Dan Kaminsky told CNET. He came up with the idea after watching the 2009 film Star Trek with a color-blind friend. It was then that he got to know more about colorblindness like its varying types and degrees. A vast majority, for instance, have trouble seeing red or green due to a genetic defect . Blue-yellow colorblindness, however, is rarer and develops later in life because of aging, illness or head injuries, etc. He started experimenting with one of the most common representations of points in the RGB color model. What the DanKam app attempts to do is to clean up the color space of the image or video signal so that colors can be _ to those suffering from viewing problems. "You can adjust the app to fit your needs. There is a range and not everyone who is color-blind sees things the same." Says Kaminsky. Sparkman, a copy editor at CNET, tried out the app and was pleased with the results. "It would be useful for dressing for a job interview," he said. But using it for his art is "the most practical application." It worked well on LED and other lights on electronic gadgets, which means Sparkman can now identify the power light on his computer display as green. How does DanKam's app work? | [

mmlu_train_6505 | When Nick Pasqua hits his bedroom after school, he's tired. The 14-year-old high school freshman from New Rochele, New York, plays computer video games online for a couple of hours, pausing only to instant-message his friends, check his blog or download a new song to his IPOD. When his cell phone vibrates , he scans the text message and fires back a reply. "We're leagues behind," sighs Nick's mom, Kimberly Pasqua, 45. And many parents like her are feeling increasingly out of step with their children. The technology gap between parents and kids is widening, says Amenda Lenhart, senior research specialist for Internet & American Life Project, a research group that explores the impact of the Internet on children and families. In a series of reports released last year, researchers found that 87 percent of the prefix = st1 /United States' kids aged 12 to 17 use the Internet, compared to only 66 percent of adults. Half of those teens go online daily. Eighty-one percent play games online and 75 percent use instant-messaging. Nearly half(45 percent) have a cell phone. One out of five has a blog. Why are children increasing past their parents? Because today's kids learn to use computers by playing and think technology is fun, says Lenhart. But adults generally view computers as mere tools for work , not toys. Despite this difference, most parents realize that computers, cell phones and the like are fixtures in their children's lives. With that acceptance comes worry about what makes appropriate usage and more important, what's safe. Experts say the best way to keep up is to learn the technology for yourself. Visit blogs. Send some instant and text messages. Download music. "This stuff may never be as necessary to your life as it is to your kids," says Susannah Stern, assistant professor in the Communications Department at UniversityofSan Diego, "but you won't get their respect about online issues if you don't know what they're talking about." Children can be great teachers, so let them show you the ropes. "It's empowering for them to share their knowledge," says Stern.

mmlu_train_54676 | If music makes you smarter and exercise helps you to think, surely exercising to music can turn you into an intelligent person. A team of scientists from Ohio State University did experiments on 33 volunteers who were getting better from heart disease following operation. They found that people who exercised while listening to Italian musician Antonio Vivaldi's "The Four Seasons" did much better on language ability tests than without music. "Facts suggest that exercise improves the learning ability of people with heart disease," said the psychologist Charles Emery, who led the study. "And listening to music is thought to _ understanding. We just wanted to put the two results together," he added. The volunteers said they felt better emotionally and physically after working out with or without the music. But their improvement on the test doubled after listening to music during exercise. Scientists have proved that music can be good for health, education and well-being. It helps reduce stress, sadness and nervousness; encourages relaxation or sleep; wakes up the body and improves memory and thoughts. In medical fields, music is used widely for patients who have had head hurts before and after operation. "The Four Seasons" was used because of its moderate tempo and positive results in earlier research. "Exercise seems to cause positive changes in the nervous system and these changes may have a direct result on learning ability," Emery said. Scientists have been studying the results of music on understanding since the early 1950s. By 2000, psychologists were using Mozart's music, especially his violin pieces, to help children with speech disorders. Mozart was chosen because his music is not overexciting and has clear structures. A study showed students who listened to Mozart went on to score higher marks in an intelligence test. With important exams drawing near, your parents will not probably allow you to listen to music. But perhaps now you have good reasons to argue with them. The text mainly tells us that _ . | [

The American schoolboy, Shubham Banerjee, made a new Braille writer from a Lego tool that lets people create robots. Banerjee has called his new machine the Braigo - a combination of the words Braille and Lego. It costs just $ 350. It works by changing electronic text into Braille and then printing it using a computer or mobile machine. Banerjee designed his Braigo last year for a school science exhibition. Since then, he has caught the interest of Silicon Valley in the USA. The big technology company Intel spent money on Banerjee's machine last November, but they did not say how much money they put in. Banerjee also got $35, 000 from his father to help him start the project. His father works as a computer engineer at Intel. He spoke about why he gave so much money to his son, saying:"We as parents started to be interested more, thinking that he's on to something and this invention has to continue."

mmlu_train_5511 | People are more likely to wash their hands properly after using the toilet if they are shamed into it or think they are being watched, scientists said on Thursday. Hand-washing is the cheapest way of controlling disease but less than one third of men and two thirds of women wash their hands with soap after going to the toilet, a British study by the London School of Hygiene and Tropical Medicine showed. But when prompted by an electronic message flashing up on a board asking: "Is the person next to you washing with soap?," around 12 percent more men and 11 percent more women used soap. Health authorities around the world are stepping up efforts to persuade people to be more hygienic and wash their hands properly to help slow the spread of H1N1 swine flu, which was declared a pandemic by the World Health Organization in June. "Hand-washing with soap has been ranked the most effective way for the worldwide control of disease," the study's authors wrote. "It could save more than a million lives a year from diarrhoeal diseases, and prevent respiratory infections -- the biggest causes of child mortality in developing countries." In developed nations, hand-washing can help prevent the spread of viral infections like flu and sickness and diarrhea bugs like norovirus and rotavirus, as well as hospital-acquired infections like MRSA and C-difficile, the authors said. The researchers studied the behavior of a quarter of a million people using toilets at motorway service stations in Britain over 32 days.Use of soap was monitored by sensors. The study, published in the American Journal of Public Health to mark Global Hand-washing Day, showed that with no reminders, 32 percent of men and 64 percent of women used soap.

mmlu_train_81708 | Not all memories are sweet. Some people spend all their lives trying to forget bad experiences. Wars and traffic accidents can leave people with terrible physical and mental _ Often they appear again in dreams. Now American researchers think they are close to developing a pill , which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce , or possibly erase the effect of sad memories. In November, some scientists tested a drug on people in the US and France. The drug stops the body producing chemicals that fix memories in the brain. So far the research has suggested that only the mental effects of memories may be reduced, not that the memories are erased. The research has caused plenty of argument. Some think it is a bad idea, while others support it. Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war. They say that there are many people who suffer from terrible memories. "Some memories can destroy people's lives. They come back to you when you don't want to have them in a dream. They usually come with very sad feeling." said Roger Pitman, a scientist of psychiatry at Harvard Medical School. "This could relieve a lot of that suffering." But those who are against the research say that it is very dangerous to change memories because memories give us our identity . They also help us all get away from the mistakes of the past. "All of us can think of bad events in our lives that were terrible at the time but make us who we are. I'm not sure we want to erase those memories," said Rebecca Dresser.

mmlu_train_18875 | Lack of exercise is considered a risk factor for cancer. There is considerable evidence that inactivity is connected with increased risk for lung cancer, breast cancer, etc. In the Aerobics Center Longitudinal Study, more than 32,000 people (25,000 men and 7,000 women) were given a preventive medical examination that included a machine exercise test to measure physical fitness. They were given a physical fitness score, with one being the lowest and five being the highest fitness level. Then these people were followed for an average of 8 years. During this time, 179 men and 44 women died of cancer. Data from the Aerobics Center Longitudinal Study show people have lower rates of cancer with higher levels of physical fitness. Studies from the Cooper Institute for Aerobics Research in Dallas suggest that men with high fitness levels are less likely to die of cancer. The Aerobics Center Longitudinal Study also found that fitness level was more important than weight in predicting longevity . While results showed that fitness and normal weight are the ideal combination, researchers found that men who were fat but performed well in the machine performance had just a slightly increased all-cause death rate, including cancer, compared to the more slim men. The fat, but fit, men particularly lived longer than the slim, but flabby , men.

mmlu_train_35465 | Gauri Nanda sees a wearable computer as a handbag -- one that's built out of four-inch squares and triangles of fiber, with tiny computer chips embedded in it. It looks, feels and weighs like your typical leather purse. That's where similarities end: This bag can wirelessly keep track of your belongings and remind you, just as you're about to leave the house, to take your wallet. It can review the weather report and suggest that you grab an umbrella. This purse can even upload your favorite songs onto your scarf. Sure, a computing purse and scarf set may seem like the stuff of science fiction. But these devices, part of next generation of wearable computers, could become commonplace within a few years. DuPont created new super strong fibers that can conduct electricity and can be woven into ordinary-looking clothes. And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty cycle. As a result, these new wearable devices are different from the heavy and downright silly versions of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike their predecessors, these new wearable computers also make economic sense. When her bag becomes commercially available in two to three years, Nanda expects it will cost around $150, which is the price of an average leather purse. Here's how the bag works: You place a special radio-signal-transmitting chip on to your wallet. A similar radio in your purse picks up the signal and notifies you that you've forgotten to take your wallet. In turn, sensors on your purse's handles will notify the computer that you've picked up the purse and are ready to go. _ Indeed, more people will want to cross that bridge in the coming years -- making for a booming market for wearable computers that don't like something out of science fiction.

mmlu_train_37431 | If you are afraid of the dark,it's not a big deal.It's perfectly normal to feel afraid After all,animals do too. "Fear matters,"says Karen Warkentin,an ecologist."It's a good thing," she adds, "because fear makes you do things that keep you alive." Like kids,many animals experience fear and they respond to the feeling in variety of ways.A frightened turtle pulls its head and legs inside its shell.A small fish will swim away when a big,hungry fish approaches. Some animals respond to fear in ways you might not expect.The first example is that the fear of being eaten can scare some frogs right out of their eggs. Warkentin made the surprising discovery while studying red--eyed tree frogs in Costa Rica. In this species,female frogs attach jellylike clumps of their eggs to the undersides of leaves.The leaves hang on branches that dangle over ponds.After they hatch from the eggs,the tadpoles then fall into the water,where they eventually grow into adult frogs. Tree frog eggs usually grow for 6 days before hatching.If they sense that a hungry snake is about to attack,however,they can hatch up to 2 days ahead of schedule. As the snakes are unable to swim,by falling into the water early,the tadpoles can escape. If hatching early helps protect red--eyed tree frogs from snakes,you might wonder why their eggs don't always hatch sooner.It turns out that hatching early brings its own danger.Once tadpoles land in the water,hungry fish and other animals like to eat them too.Staying in their eggs for a full 6 days,then,allows frog embryos to grow big and strong.This extra growth improves their chances of surviving in the water.

"My husband and I tried to tutor her at home,but we found all our knowledge was out of date and we were only confusing Zarreen.We also tried a group revision course but all the children were sitting exams for different boards . On the whole we think one-two-one tuition works best and it is worth the money.In our case,Preeta is a bit like an elder sister to Zarreen and that's the most important,"says Ashan Sabri from London, whose daughter Zarreen,18,is having tuition in biology and chemistry in preparation for A-levels this summer. In fact,Preeta Datta is only six years older than her pupil and she is happy to provide extra tuition through mobile phone."Maybe Zarreen will call me two or three times a week with a question about biology or chemistry, and that's fine to me,"says Datta. The real question is:does tutoring do any good? "It's not the magic bullet,"says Professor Judith Ireson.'It's still up to the child to do the learning.If he or she isn't interested,then sending them to a private tutor won't do any good."

mmlu_train_86758 | Nowadays, many children spend hours a day looking at computer screens or other digital products. Some eye care doctors say all the screen time has caused more children to have what they call computer vision syndrome . Nathan Warford is an optometrist in the US. He says he has seen more children having eye problems. "More children come into my office because their parents have noticed that they have headaches or red eyes, or because their degree of short-sightedness appears to be increasing very fast and they're worried," he said. Dr. Warford says part of the problem is that even if their eyes start to feel uncomfortable or they start to get a headache, some children don't tell their parents, because they don't want their games or the computer to be taken away. Another part of the problem is that people blink less often when they look at the screen.A person who uses a computer or a digital product blinks about a third as much as we normally do in everyday life. If eyes can't stay wet or are too tired, they will not be protected like normal. Why don't some children tell their parents when their eyes start to feel uncomfortable? | [

But sometimes this balance becomes disturbed and a larger proportion of positive ions are found. This happens naturally before thunderstorm, earthquakes when winds are blowing in certain countries. Or it can be caused by a build-up of static electricity indoors from carpets or clothing, or from TV sets, duplicators or computer display screens. When a large number of positive ions are present in the air many people experience unpleasant effects such as headaches, fatigue , excessive anger, and some particularly sensitive people feel sick or even suffer mental disturbance. Animals are also affected, particularly before earthquakes, snakes have been observed to come out, rats to flee from their burrows, dogs howl and cats jump about unaccountably. This has led the US Geographical Survey to fund a network of volunteers to watch animals in an effort to foresee such disasters before they hit vulnerable areas such as California. Conversely, when large numbers of negative ions are present, then people have a feeling of well-being. Natural conditions that produce these large amounts are near the sea, close to waterfalls or fountains, or in any place where water is sprayed, or forms a spray. This probably accounts for the beneficial effect of a holiday by the sea, or in the mountains with streams or waterfalls. To increase the supply of negative ions indoors, some scientists recommend the use of ionisers. They claim that ionisers not only clean and refresh the air but also improve the health of people sensitive to excess positive ions. Of course, there are the detractors, other scientists, who dismiss such claims and are skeptical about negative/positive ion research. Therefore people can only make up their own minds by observing the effects on themselves, or on others, of a negative rich or poor environment. After all it is debatable whether depending on seismic readings to anticipate earthquakes is more effective than watching the cat. A high negative ion count is likely to be found _ . | [

mmlu_train_9878 | Although they are an inexpensive supplier of vitamins,minerals,and high--quality protein,eggs also contain a high level of blood cholesterol ,one of the major causes of heart disease.One egg yolk,in fact,contains a little more than two--thirds of the suggested daily cholesterol limit. This knowledge has caused egg sales to drop in recent years,which in turn has brought about the development of several alternatives to eating regular eggs.One alternative is to eat substitute eggs. These egg substitutes are not real eggs, but they look somewhat like eggs when they are cooked.They have the advantage of having lower cholesterol rates,and they can be scrambled or used in baking.One disadvantage, however,is that they are not good for frying,poaching,or boiling.A second alternative to regular eggs is a new type of eggs,sometimes called"designer''eggs.These eggs are produced by hens that are fed low-fat diets consisting of ingredients such as canola oil,flax,and rice bran.In spite of their diets,however,these hens produce eggs that contain the same amount of cholesterol as regular eggs.Yet,producers of these eggs claim that eating their eggs will not raise the blood cholesterol in humans. Egg producers claim that their product has been described unfairly.They use scientific studies to back up their claim.And in tact studies on the relationship between eggs and human cholesterol levels have brought mixed results.It may be that it is not the type of egg that is the main determinant of cholesterol but the person who is eating the eggs.Some people may be more sensitive to cholesterol from food than other people.In fact,there is evidence that certain dietary fats stimulate the body's production of blood cholesterol.Consequently,while it still makes sense to limit one's intake of eggs,even designer eggs,it seems that doing this without regulating dietary fat will probably not help reduce the blood cholesterol level. The main cause of the recent drop in egg sales is_. | [

mmlu_train_51971 | As any parent with an iPhone or an iPod Touch knows, mobile apps can be an engaging and entertaining experience for kids. Now, a new study of PBS Kids suggests that the experience can be an educational one as well. The study, which was administered by PBS under a grant from the Department of Education, first tested the vocabulary level of a group of 90 Title 1 school children, aged 3 to 7. Then, the children were each given two weeks with an iPod Touch loaded with the Martha Speaks Dog Party app created by PBS Kids. The study monitored how the children used the iPod, during what hours, and in what context. On average, the study found that kids played with the iPod Touch for a total of 5 hours across the two weeks, with half that time spent playing the Martha Speaks app. At the end of the two week trial, the children were given another vocabulary test, which revealed an increase in vocabulary acquisition by as much as 31 per cent. The study findings are particularly useful as smart phones and mobile devices have become increasingly popular among families and parents are faced with a proliferation of mobile apps designed for kids. According to a recent Nielsen study, smart phone usage is 12% higher in households with children than other households. "Mobile apps can be a great learning tool in the hands of children," said Lesli Rotenberg, SVP, Children's Media, PBS. "This research is important in helping to better understand and guide the development of new apps that improve the value of children's screen time with significant educational outcomes."

mmlu_train_42303 | A villa designed to resist earthquakes with "self-healing" cracks in its walls, thanks to nanotechnology applications with self-healing polymers , is to be built on a Greek mountainside. The villa's walls will include special particles that turn into a liquid when squeezed under pressure, flow into cracks, and then harden to form a solid material. The NanoManufacturing Institute (NMI), based in Leeds University, will play a key role in an EU project to construct the home by December 2010. The project, called "Intelligent Safe and Secure Buildings" (ISSB) is funded under the EU's Sixth Framework program. This potentially life-saving scheme is led by German building manufacturer Knauf. The villa will be built in Amphilochia, in western Greece, where Knauf currently runs a manufacturing plant. If the experiment is successful, more tremor-resistant homes could be built in earthquake zones across the globe. NMI chief executive Professor Terry Wilkins said, "What we're trying to achieve here is very exciting. We're looking to use polymers in much tougher situations than ever before on a larger scale." Monitors contained in the villa's walls will be able to collect vast amounts of data about the building over time. Wireless sensors will record any stresses and vibrations, as well as temperature, humidity and gas levels. The walls are to be built from new load-bearing steel frames and high-strength gypsum board. Prof Wilkins said, "If there are any problems, the intelligent sensor network will be able to alert residents immediately so they have time to escape. If whole groups of houses are so constructed, we could use a larger network of sensors to get even more information. If the house falls down, we have got hand-held devices that can be used over the ruins to pick out where the embedded sensors are hidden to get some information about how the villa collapsed. Also, we can get information about anyone who may be around, so it potentially becomes a tool for rescue." What Prof Wilkins said suggests that _ . | [

mmlu_train_22426 | Internet reports of whales sounding like people are not new. But in this case in San Diego, California, scientists for the first time recorded the utterances, did an acoustic analysis and were surprised to find a rhythm similar to that of human speech, Sam Ridgway of the National Marine Mammal Foundation reported on Monday. The sounds marking is quite special : Whales make sounds through the system of the nose, unlike people, who use their throat. So this particular with whale had to make some tricky muscular and blowhole adjustments. "Such obvious effort suggests motivation for relatin", said Ridway, the main author of a study featured in the journal Current Biology. "The sounds we heard were clearly an example of vocal learning by the white whale." The wale, named Noc, died five years ago. Ridgway says that back in 1984, he and others started hearing sounds near the whale and dolphin enclosure that recalled two people speaking in the distance, too far away to be understood. The sounds were later traced to one particular white whale when a diver in its tank came to the surface because he thought he heard colleagues tell him to do so. Noc had lived among dolphins and other white whales and had often been in the presence of humans. The whale made human-like sounds for around four years until it reached the age of sexual maturity, Ridgway said. It can be inferred from the text that _ . | [

mmlu_train_9591 | When Siva Kalyan was born, his backbone was deformed resulting in a lifelong difficulty in walking. But that hasn't stopped the nine-year-old from becoming a prodigy . Until he was three-and-a-half years old, Siva could not even crawl. Wanting the best treatment for their son, Siva's parents moved with him from India to Australia and later to the USA. In the USA, his parents enrolled him in the second grade based on his age. But his teachers soon realized they had a genius. Siva was then tested for the eighth grade, but it was soon found out that he was actually qualified for college courses. As one advanced course was not enough, the brilliant boy is now taking two courses from Stanford University. Due to the treatment he received, Siva's physical condition has improved as well. But none of _ "just happened". It was his parents' understanding and correct guidance, and the loving care of his grandparents that contributed to the growth of the genius. Siva's highly educated and hardworking family has brought him up on the basis of certain principles. The family believes that once a strong foundation is built for the child in English and mathematics, the child is equipped to master any other subject, law, history, or engineering. It is equally important to recognize the strengths of a child rather than forcing the child to do things that he may not want to do. Siva's parents helped. Siva focus his energies on his strength, which is mathematics. At the same time they took care to see that he had friends to play with and enjoyed a few recreational activities. The only activity that's restricted for Siva is viewing television. Siva watches TV only for 30 minutes a day and video games are a bonus for special occasions. Thanks to his mother who is a singer, Siva has also learned music and even won the first and second prize at two competitions. In sports, he likes to swim. He began to learn swimming to strengthen his muscles, and by the age of eight he was able to swim a kilometer in both the backstroke and the freestyle. Why did Siva's parents move to the USA? | [

mmlu_train_57146 | The spread of Western eating habits around the world is bad for human health and the environment. These findings come from a new report in the journal Nature. David Tillman, a professor of ecology at the University of Minnesota, America, examined information from 100 countries to identify what people ate and how diet affected health. He noted a movement beginning in the 1960s. He found that as nations industrialized, population increased and earnings rose, more people began to adopt what has been called the Western diet. The Western diet is high in sugar, fat, oil and meat. By eating these foods, people began to get fatter and sicker. David Tillman says overweight people are at greater risk for non-infectious diseases like diabetes and heart disease. Unfortunately when people become industrialized, if they adopt this Western diet, they are going to have these health problems, especially in developing countries in Asia. China is an example where the number of diabetes cases has been jumping from less than one percent to 10 percent of the population as they began to industrialize over a 20-year period. And that is happening all across the world, in Mexico, in Nigeria and so on. And, a diet bad for human beings, is also bad for the environment. As the world's population grows, more forests and tropical areas will become farmland for crops or grasslands for cattle. We are likely to have more greenhouse gas in the future from agriculture than that coming out of all forms of transportation right now. Mr. Tillman calls the link between diet, the environment and human health, "a trilemma": a problem offering a difficult choice. He says one possible settlement is leaving the Western diet behind.

mmlu_train_57186 | BEIJING - The country's top health officials state that an international charity's decisions not to give millions of dollars to Chinese organizations that fight AIDS and other diseases will not bring about the end of those organizations. The Global Fund to Fight AIDS, Tuberculosis and Malaria announced on Monday that it will withhold $95 million from the $270 million in grants it had planned to give China. That decision came as the result of months of discussion between the charity and Chinese officials. On the mainland, a large number of programs meant to prevent the spread of HIV/AIDS have received money from the Global Fund. Many observers now fear that the announced cut will undermine those organizations' work. Chen Zhu, the minister of health, said officials have found a way to limit the harm. "In the coming five years, the Chinese government will constantly increase its financial support of social organizations, particularly those that work to control and prevent HIV/AIDS." Chen said while addressing the 6th Experience Exchange Conference of International Cooperation Program on HIV/AIDS in China on Monday. In a recent survey of more than 200 organizations taking part in the fight against HIV/AIDS on the mainland, nearly 80 percent of them said they had received grants from the Global Fund. About 83 percent of them said they will find it difficult to continue operating without financial support from abroad, it said. Official statistics showed the Global Fund has given China $548 million in grants since 2003. Xia Jing, leader of a Beijing-based grassroots organization dedicated to controlling AIDS, said: "We were like children fostered by foreign milk. As foreign money began to be withdrawn from China, we were faced with serious financial hardships." Han Mengjie, executive director of Global Fund China Programs, said the Chinese government has fully recognized the important role social organizations play in controlling diseases. "The work done and efforts made by such organizations must be sustained for a long time to supplement the government's intervention work,"he said, "We have to face the truth that international money for AIDS control will gradually leave China and to prepare ourselves to deal with that."

This funny-looking animal has feet and is a kind of warm-blooded mammal. While other mammals usually keep their blood at around 37 degrees, the platypus has a lower body temperature of 32 degrees. As to its appearance, the platypus'mouth is not really like ducks'at all; its mouth actually looks a bit soft. The platypus closes its eyes when swimming. It uses its mouth to pick up outside information made by the creatures underwater. Strangest of all, the platypus is a mammal that can lay eggs. And there is only one other kind of mammal that can lay eggs, the echidna of Australia. Both the platy-pus and the echidna lay soft-shelled eggs, and both feed their young with their own milk that comes out of their skin. These animals also walk in a way that is similar to crocodiles , with legs on the sides of their bodies rather than under them.

The FCX is the first fuel-cell-powered car to be used by a family anywhere in the world. The FCX uses hydrogen and oxygen for fuel. Car makers have been working to develop vehicles that are better for the environment. They are developing cars that use fuel other than gasoline. And then what is fuel cell technology? Fuel cell technology works by changing the chemicals hydrogen and oxygen into water. This process produces electricity, and water vapor which comes out of the exhaust pipe. Most cars release dangerous gases such as carbon monoxide and carbon dioxide. Many scientists say these gases are major contributors to global warming. "The FCX is driven just like any other vehicle on the road, but without the gases which pollute the environment," scientists say. Fuel cell technology has been around since the 1800s, but scientists have yet been to perfect it. They say it may take years before the technology is ready for widespread use.
