mmlu_train_32572 | Can you remember a morning when you've woken up to the ring of your alarm clock and wished you could stay in bed? You haven't slept well, your hair is a mess. Worse, you can't stop yawning. Yawning is universal to humans and many animals. Cats, dogs and fish yawn just like humans do! Yawning is an involuntary(,) action during which you open your mouth and breathe deeply. The average duration of a yawn is about 6 seconds. The purpose and cause of yawning are still a mystery. Scientists are not sure what causes a yawn. People yawn when they are tired or bored, but they also yawn when they aren't. There are many ideas explaining why we yawn. One idea is that yawning is a way for the body to become more alert by taking in more oxygen. A yawn increases the heart rate, forces carbon dioxide out of the lungs and blood stream, and brings oxygen to the brain. But one study showed that volunteers given a lot of oxygen did not yawn any less than before, while those given a lot of carbon dioxide did not yawn more. Another idea is that early humans used yawning as a form of communication. If one decided it was time to sleep, they would tell the others by yawning and they would do it in return to show they agreed. A third explanation comes from psychology professor Gordon Gallup of University at Albany in New York. He said that as people yawn, they cool off their brains. "Brains are like computers." he said. "They only operate efficiently and effectively when they're cool. Many things connected to yawning, like being tired, make the brain hot, and yawning can reduce the heat." Scientists have sent people into space, and created terrible nuclear weapons, but there are lots of seemingly simple things, such as why we yawn, or hiccup , that they can't figure out. Next time you are in class in the morning, let out a big yawn and watch to see how many of your classmates yawn in response! In which situation are you likely to yawn? | [

mmlu_train_48132 | Sixty-five million years ago, an asteroid that crashed on Earth led to the disappearance of the largest animals that have ever walked our planet - the dinosaurs. At least, this is what some scientists believe. But that accident happened so long ago. People have come to believe that we are free of threats from asteroids and everything else from space. However, what happened on Feb 15 , 2013 was a reminder that we're just as _ as the dinosaurs once were. Two objects from space - a meteor and an asteroid called 2012 DA14 - visited Earth's atmosphere on the same day. The former fell in Russia, injuring 1,200 people, while the latter passed by Earth at a record-setting close distance. Scientists had been expecting the asteroid since last year, but the meteor was a surprise. NASA's telescope system only detects asteroids at least 50 meters in diameter , which is just about the size of 2012 DA14. But the meteor was much smaller, which made it harder to spot. But what if we do spot an asteroid that is headed right for Earth? There are several possible ways in which dangerous asteroids could be made to change its orbit. Which method is best depends on several factors and most importantly - how much time we have to stop it. If there is enough time before the hit, we can send off a heavy spacecraft to travel alongside the asteroid. The gravity from the spacecraft would gradually change the rock's orbit. Besides that, scientists could one day use sun-powered lasers to either make asteroids disappear or change their course. If there's not enough time, we'll have to go after the asteroid with a spacecraft and change its orbit with a crash. Finally, if things are truly desperate, there will be only one choice left - to use a nuclear bomb. That could turn the asteroid into a meteor shower, which would be even more dangerous. The author mentioned the asteroid that led to the dinosaurs' dying out to _ . | [

mmlu_train_52446 | For a long time, people who fish have had to rely on luck to catch fish. Even big fishing ships, fitted out with radar and modern equipment, have their share of bad days. Wouldn't it be nice if fish could be trained to come at the call of a whistle the way some days are trained? Well, the days of "fish whistle" may be just _ . Japanese companies are working on methods that will train fish to return to harvest areas at the sound of an underwater whistle. The method works like this: First, fish eggs are hatched in a laboratory. Whenever feeding time arrives, a whistle sounds. The young fish learn to return to their feeding areas at the sound of the whistle. Later, the fish are set free at sea, near special-made under water "barns". There, the whistle-plus-feeding program continues. Being well fed and sheltered, the fish continue to live around the barn. So when fishing time arrives, all the harvesters need to do is to sound the whistle, drop their nets, and draw in a lot of fish. Many countries have closed their offshore fishing waters to ships from other countries. With fish whistle and barns, Japan hopes to become less dependent on importing fish from other countries. We may infer from the passage that _ . | [

"Japan is still a country depending on importing fish",

mmlu_train_30611 | Beijing ?(13, July) China sent up a new data relays atellite , 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-SC 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 (1), 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 m low-Earth orbits, such as manned spacecraft and remote sensing satellites, from a higher position m outer space.Only three satellites of this kind are needed to form a global communication network, and China has two now."

mmlu_train_5731 | A "talking kitchen" teaches students how to cook French dishes and speak French. Researchers at New Castle University have developed the French Digital Kitchen. Professors Paul Seedhouse and Patrick Olivier led the project. Professor Seedhouse says that it works like a satellite navigation system in a car. The kitchen equipment and tools use motion sensor technology similar to the Nintendo Wii game system. The sensors help a computer guide the students through instructions in French. The system can tell whether you've done what you were asked to do or not. For example, the system tells you to take some butter and cut it with a knife. There's a sensor on the package containing the butter so it can tell where the butter's being moved. The sensor in the knife not only knows that the knife is moving, but it also knows what motion the knife is making. So it can tell whether the knife is being used. And so it doesn't go on to the next stage of the program unless you've done what it tells you to do. Students can ask the computer to repeat the instructions or translate them into English. There are vocabulary lessons before and after the cooking. Professor Seedhouse became interested in the idea after he visited a talking kitchen designed for a different purpose. "It was actually for communicating with people who suffer from dementia " .And so, for example, it can speak to those people and tell them that they've left the cooker on and they should turn it off." The original purpose of the talking kitchen is to _ . | [

mmlu_train_20267 | Don't drive your kids to school. Let them ride a bike to school. In England 8.3 million children travel to school every day. It is reported that only a small number of pupils cycle to school (under 2%), although one in three children would actually like to. Experts say that to stay healthy, children need at least one hour of moderate exercise every day. But only six out of ten boys and four out of ten girls get that. One of the reasons is that parents have developed a habit of driving their children to school when they could just walk or ride a bike to school. Teachers often say that children who walk or ride a bike to school are more ready to listen to their classes, ask and answer questions in class than those driven by car, and the school journey is a good chance for children to learn about road safety and other life skills. Also, for many children, riding a bike is more fun than going to school by car. Most parents know the benefits . Then what's stopping them from letting their kids ride a bike? Safety is the number one worry for them. But actually riding a bike is not as dangerous as parents think it is. When you decide to buy a bike, you should be aware that a bike that is too big or too small is dangerous. Don't try to get a bike that your child will "grow into". Get the right size in good working order. Generally, 20-inch wheels are on bikes for 5-8 year olds; 24-inch wheels are for 9-11 year olds; 26-inch wheels are suitable for those over 11, and some older children should even take bikes with 28-inch wheels, but the main thing is that the bike fits your child. Which of the following benefits of cycling to school is NOT mentioned in the passage? | [

mmlu_train_43065 | Millions of young people are writing blogs . Millions of others are reading them. The word "blog" is a short way of saying Web log. Many popular Web sites now offer free, easy ways to create personal Web pages and fill them with writings and pictures. Web sites called "Face book" and "My Space" are some of the most popular blog sites for young people. Blogs offer young people a place to show their writings and feelings. They can also be helpful to connect young people with others. But blogs can become dangerous when they are read on the Internet by millions of people all over the world. Recent studies show that young people often tell their names, age and where they live on the Internet. That may not be safe for them. This personal information puts them in danger when found out by dangerous people who want to hurt them. Students can also get into trouble when they put information about others on their blogs. As a result, many schools don't allow using blogging web sites on school computers. Many schools have also begun teaching parents about the web sites. Parents should know what their children are doing online and should read their blogs to make sure they are not giving out personal information.

Her birth went well ,but his was a different story. The doctor struggled for 20 minutes to save Jamie before announcing him dead. "His little arms and legs were just falling down away from his body." Kate Ogg said ,"I took off my coat and put him on my chest with his head over my arm." She and her husband, David ,said to the child as she continued to hold him for nearly 2 hours. During that time, the two-pound baby showed the sign of life. She said , "I told my mum ,who was there, that he was still alive. Then he held out his hand and grabbed my finger. "Their tiny baby grew stronger and stronger in his mother's arms, and their final goodbye turned into a hello.

The study offered two new results from earlier findings, It said taking one aspirin pili every other day helped only healthy men over the age of fifty.It also said aspirin gave the greatest protection against heart attacks to men with low blood cholesterol levels. Earlier in the United States began a major aspirin study in the early 1980s.It included 22,000 healthy men doctors.Ail were between the ages of forty and eighty-four.More than 11,000 of the doctors took a harmless pill that contained no drug.The men did not know which kind of pill they were taking. The doctors who took aspirin suffered 44% fewer heart attacks than those taking the harmless pill.139 men who took aspirin suffered from heart attacks.Ten of them died.239 men who did not take aspirin suffered from heart attacks.Twenty-six of them died. The researchers said the doctors' study provides clear proof that taking aspirin can prevent a first heart attack in healthy, older men.They said, however, the result does not mean every man over the mage of fifty should take aspirin.They said aspirin couldn't help men who do not eat healthy foods, who smoke cigarettes and who are fat.The researchers said men who think they wou3d be helped by taking aspirin should talk with their doctors first.

mmlu_train_14500 | Sleeping in on Saturday after a few weeks of too little shuteye may feel refreshing, but it can give a false sense of security. New research shows long-term sleep loss cannot be cured that easily. Scientists researched the effects of short- and long-term sleep loss and found that those who suffer long-term sleep loss may function normally soon after waking up, but experience steadily slower reaction times as the day goes by, even if they had tried to catch up the previous night. The research has important safety significances in an increasingly busy society, not just for shift-workers but for the roughly one in six Americans who regularly get six hours or less of sleep a night. "We know that staying awake 24 hours without sleep will affect your performance to do all sorts of things, and this effect equals to drinking too much when driving," said lead researcher Dr. Daniel Cohen of Boston's Brigham and Women's Hospital. But when those who suffer long-term sleep loss become all-nighters, "the harm is increased ten times," Cohen said. The National Institutes of Health says adults need seven hours to nine hours of sleep for good health. Regularly getting too little sleep increases the risk of health problems, including memory impairment and a weakened immune system. More immediately, too little sleep affects reaction times; sleepiness is to blame for car crashes and other accidents. It has critically important complicated and unexpected results for anyone who works "crazy hours" and thinks they are performing fine with a few hours of weeknight sleep, said Harris, director at New York's Montefiore Medical Center.

That is true, the time of day when you feel most energetic is when your cycle of body temperature is at its peak . For some people the peak comes during the forenoon . For others it comes in the afternoon or evening. No one has discovered why this is so. Much family quarrelling ends when husbands and wives realize what this energy cycle means and which cycle each member of the family has. You cannot change your cycle, but you can learn to make your life fit it better. "Habits can help," Dr. Cleiman believes. If your energy cycle is low in the morning but you have an important job early in the day, rise before your usual hour, and then you will work better at your low point.

That's how millions 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 is naturally good at laughing -- it's the common language. We want people to feel happy with their lives." There are now more than 500 Laughter Clubs in India and over 1,300 in the world. Many doctors are also interested in the effects of laughter on our health. According to a 5-year study at the UCLA School of Medicine in California, with laughing there is less stress 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 silly. 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 real laughter and unreal 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_11451 | The Internet is full of headlines that grab your attention with buzzwords . But often when we click through, we find the content hardly delivers and it wastes our time. We close the page, feeling we've been cheated. These types of headlines are called "click bait". A headline on Busin,esslnsider.com reads: "This phrase will make you seem more polite". First, when you click through, you find another headline: "Four words to seem more polite." Then, on reading the article, you find it's actually an essay about sympathy. And what are the four words? They're "Wow, that sounds hard." On some video websites, you might encounter headlines such as "Here's what happens when six puppies visited a campus". Turns out it's just some uneventful dog footage . Nowadays, with the popularity of social media, many news outlets tweet click bait links to their stories. These tweets take advantage of the curiosity gap or attempt to draw the reader into a story using a question in the headline. These click bait headlines are so annoying that someone is attempting to save people time by exposing news outlet click bait through social media. The Twitter account @SavedYouAClick, run by Jake Beckman, is one such example. Beckman's method is to grab tweets linking to a story and retweet them with a click-saving comment. For example, CNET tweeted "So iOS 8 appears to be jailbreakable but...", with a link to its coverage of Apple's product announcements. Beckman retweeted it with this comment attached: "... it hasn't been jailbroken yet." Since founding the account, Beckman's Twitter experiment has brought him more than 131,000 followers. Beckman said that @SavedYouAClick is "just my way of trying to help the Internet be less temble."

mmlu_train_8479 | Why can some people sleep through noises like a honking car or flushing toilet, while others are awakened by the lightest sound? To find the answer, sleep researchers at Massachusetts General Hospital conducted an unusual study of 12 self-described deep sleepers. After tests confirmed that the healthy volunteers were solid sleepers, they took part in a three-night study in the university's sleep laboratory. The participants spent the night in a big and comfortable room. But the room also included four speakers positioned near the top of the bed. During the night, the deep sleepers were subjected to 14 different recorded sounds, like street traffic, toilets flushing, an ice machine dispensing and an airplane flying overhead. Next door, the researchers monitored their sleep patterns and brain waves. As expected, all of the participants slept ly well, but there were differences in how they responded to the noisy interruptions. Some of the sleepers didn't wake up even when a sound was blasted at 70 decibels ; others were awakened by sounds at 40 or 50 decibels. The researchers discovered that the difference in a sleeper's reaction to noise could be predicted by the level of brain activity called "sleep spindles''. A sleep spindle is a burst of high-frequency brain activity coming from deep inside the brain during sleep. The source of the spindles is the thalamus, a part of the brain that sends sensory information to the rest of the cortex . Before the study, the Massachusetts researchers theorized that the spindles are the brain's way of preventing sensory information from passing through the thalamus and waking the rest of the brain during sleep. They found that the sleepers who experienced the most sleep spindles during the night were also the soundest sleepers and were least likely to be awakened by noise. Scientists already know that most people become lighter sleepers with age, most likely because older people experience less "slow wave sleep'', which is the deepest stage of sleep. People also produce fewer sleep spindles as they age. But even when controlling for the stage of sleep a person was in, the number of sleep spindles still predicted their risk for awakening because of noise. More research is needed, but the findings suggest that a better understanding of sleep spindles could lead to new behavioral or drug therapies for people with sleep disorders. For instance, future studies may try to determine whether diet, exercise or other behaviors may influence the number of sleep spindles a person produces during the night. It can be learned from the passage that _ . | [

mmlu_train_51975 | Most of us are used to seasons. Each year, spring follows winter, which follows autumn, which follows summer, which follows spring. And winter is colder than summer. But the earth goes through temperature cycles over much longer periods than those that we experience. Between 65,000 and 35,000 years ago, the planet was much colder than it is now. During that time the temperature also changed a lot, with periods of warming and cooling. Ice melted during the warm periods, which made sea levels rise. Water froze again during the cold periods. A new study from Switzerland, sheds light on where ice sheets melted during the ice age. It now seems that the ice melted at both ends of the earth, rather than just in either northern or southern regions. This surprised the researchers from the University of Bern. Scientists have long assumed that most of the ice that melted was in the Northern hemisphere during the 30,000-year long ice age. That belief was held because the North Pole is surrounded by land, while the South Pole is surrounded by the Antarctic Ocean. It is easier for ice sheets to grow on land. If surrounded by sea the ice can easily just slip into the ocean instead of building up. The researchers used a computer model to look at ways the ice could melt and how it might affect sea levels. They compared these results to evidence of how temperatures and currents actually changed during that time. The model showed that if it was only in the Northern hemisphere that ice melted, there would have been a bigger impact on ocean currents and sea temperatures than what actually happened. Studies suggest that melting just in the Southern hemisphere would have been impossible, too. The only reasonable conclusion, the scientists could make, was that ice melted equally in the North and the South. It is still a mystery as to what caused the temperature changes that caused the ice to melt. Which of the following is the best title for the passage? | [

It's always a good idea to put on your seat belt when you're in a car. Why? Think about this example: You put an egg on a skateboard and give it a push. If the skateboard hits a stone, it will stop, but the egg won't. It will fly through the air, hit the ground and break. Now, think what would happen if you tied the egg to the skateboard. When the skateboard hits a stone, the egg won't go flying; it will stay safely on the skateboard. Volvo, a famous Swedish carmaker, was the first to use seat belts in 1849. Air bags are also very important for car safety, because sometimes a seat belt isn't enough. If the car is going really fast and runs into something, seat belts could even hurt the people who wear them. Most new cars have air bags in front of and next to the seats.

It's the largest known theft on the Internet, according to a report of The New York Times. Cyber security firm Hold Security discovered the security breach( ). The firm found that the group of criminals collected personal information from 420,000 websites, including household names and small Internet sites. The criminals were based in a small city in south central Russia. They hacked websites inside Russia as well as big companies in the U.S. and other countries ,The New Times reports. The criminals found hundreds of thousands of weak websites and attacked their coding,Hold Security said. Alex Holden is chief information security officer of Hold Security. "The hackers did not just target U.S. companies;they targeted any website they could get," Holden said. "And most of these sites are still easy to attack". According to Hold Security, the criminals have been using the stolen information to send junk mail through e-mail and on social networks like Twitter. They can also use the 500 million stolen e-mail -addresses to plan other crimes. They could use information from bank e-mails to steal your identity or sell the e-mail address to other criminals to make quick cash. The reported break-ins are the latest events to raise doubts about security at big and small companies. Last winter, hackers stole 40 million credit card numbers and 70 million addresses, phone numbers and other personal information from the retailer Target Corp. The brand is still working to regain its shoppers' trust. John Prisco is a CEO of a security firm. He says security hacks are more common than many people and companies realize.

"Google Glass is a tiny computer that sits in a lightweight frame, and rests neatly above your eye and it makes exploring and sharing the world around you a lot easier," said Chris Dale, the Senior Manager of Communications for Google Glass. The glasses have a tiny video screen and a camera that connect wirelessly to the Internet through WIFI, a smartphone, or a tablet computer. You can make and receive calls, send and receive texts, take pictures, record video or search the web. You control Google Glass using your voice, and a touchpad on the right arm of the frame. Professor Marcia Dawkins is among a select group of people who have been given a chance to test out Google Glass. "I thought this is something I definitely need for my classroom and hopefully for my personal life too." The Professor's Google Glass looks like a pair bright orange glasses, without the actual glass. But there's a tiny rectangular glass at the top right-hand corner. Through that glass, she has been recording video while biking. She also has been able to talk to her sister in Thailand, and she plans to use the device to teach a public speaking class. But not everyone is excited about Google Glass. Some are concerned about possible risks to privacy. John Simpson is the director of the privacy project at Consumer Watchdog. "It is going to allow people to come in and spy on you and record that, without you knowing what is going on." Filmmaker Chris Barrett showed just how easy it is to record people without them knowing it. His glass captured a man getting arrested after a fight. He shared the video on You Tube. Also some are concerned about the use of facial recognition technology on Google Glass. But Google says it will not approve the use of such applications.

Now designers in the Netherlands are planning to create a complete building. If it all goes to plan, you will see the first house to be made from 3D printing before long. It's been named the Landscape House. Following its success across different industries, Dutch architect Ruijssenaars believes printing technology has come far enough to create the first full size building. He said, "With 3D printing, you can actually directly print the shape that you want without first having to make the mould. It is not only an interesting technique, because you have actually density of printing that you can later see in the product, but it's also economically (better) because you save time and energy." To create his design with traditional construction methods, builders would have to pour concrete into specially constructed moulds and these would have to be removed once the concrete had set. The house will occupy about 1.115 square meters and if it stays within the projected budget, it is predicted to cost between 5 and 6 million US dollars. The house will occupy about will employ is the creation of Enrico Dini. He said, "My personal approach in 3D printing of building construction is: using 3D printing as our start basis of making free form cages and from then move on with the traditional construction technique."

The five-part series, to be broadcast from Thursday July 14 at 8:30 p.m. on ABC TV, also looks at the scientists' work for the future of mankind. The scientists were a small group of pioneers who explored a world too small to see. What they found there answered some eternal questions--What is life? How is it made ? Why are children like their parents? DNA is without doubt the most powerful substance on earth. The order of its chemicals determines whether a child has her mother's eyes or her father's smile. But as DNA shows, until 50 years ago, almost no one knew of its existence. All that changed when two unknown scientists - Jim Watson and Francis Crick -ran into a pub in Cambridge shouting that they'd found the secret of life. This declaration heralded a momentous discovery, not just for the human race but for the people involved. As this program shows, it was one of the most heated scientific races the world has ever seen. Dr Watson takes us back 50 years, guiding us through the tumultuous events that led to the creation of a double helix model being built by Dr Francis Crick and himself. He tells how he and Crick try hard to find the double helix first and win the Noble Prize. The program shows others involved with the DNA story, including Maurice Wilkins, who helped create the atom bomb. He became disillusioned with the science of death and chose the science of life instead, by looking for the structure of DNA. The purpose in writing this text is to _ . | [

mmlu_train_66714 | Scientists have devised a way to determine roughly where a person has lived using a strand of hair, a technique that could help track the movements of criminal suspects or unidentified murder victims. The method relies on measuring how chemical variations in drinking water show up in people's hair. "You're what you eat and drink, and that's recorded in your hair," said Thure Cerling, a geologist at the University of Utah. While U.S diet is relatively identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as rain clouds move. Most hydrogen and oxygen atoms in water are stable, but traces of both elements are also present as heavier isotopes . The heaviest rain falls first. As a result, storms that form over the Pacific deliver heavier water to California than to Utah. Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair, scientists can construct a geographic timeline. Each inch of hair corresponds to about two months. Cerling's team collected tap water samples from 600 cities and constructed a map of the regional differences. They checked the accuracy of the map by testing 200 hair samples collected from 65 barber shops. They were able to accurately place the hair samples in broad regions roughly corresponding to the movement of rain systems. "It's not good for pinpointing ," Cerling said. "It's good for eliminating many possibilities." Todd Park, a local detective, said the method has helped him learn more about an unidentified woman whose skeleton was found near Great Salt Lake. The woman was 5 feet tall. Police recovered 26 bones, a T-shirt and several strands of hair. When Park heard about the research, he gave the hair samples to the researchers. Chemical testing showed that over the two years before her death, she moved about every two months. She stayed in the Northwest, although the test could not be more specific than somewhere between eastern Oregon and western Wyoming. "It's still a substantial area," Park said "But it narrows it way down for me." What is the practical value of Cerling's research? | [

Whether you have one computer in the house or five, you should think the following things as you make a final decision. There is a certain number of danger if you allow your children to have a computer with Internet in their rooms with no parental direction. They may share improper information and chat with strangers if they know that no one will be watching. This does not mean that you cannot allow your children to have a computer in their rooms. Think allowing a computer without Internet. This is especially useful for teens who use the computer for creative projects, playing video games and listening to music. Keep in mind, however, that it is possible that your kids are more skilled at computers than you are and may remove any blocks you have in place. Computer Use The way your family computers are used will play a role in deciding where they should be placed. A machine used only for homework will need to be in a quiet place where there is low traffic. One used for chatting online can be in the room where most of the family spend their time. If Mom and Dad use a computer for work, those needs will also have to be thought. Space Space must also be considered in computer placement. The computer will need electricity, plenty of desk space and a spot away from this bright light of windows. You will not want it placed in a room where your kids may be noisy.

mmlu_train_46331 | Google is preparing for changes in its privacy policy beginning March 1st. The company says it plans to replace more than 60 separate policies for different products with one main policy. Privacy activists criticized last month's announcement. They are concerned that the new policy will make it easier to track the activities of users across Google's many products -- from Gmail to YouTube. Marc Rotenberg heads the Electronic Privacy Information Center in Washington. He says Google's aim is to create a single unified profile of its users. "We believe that not only is that a threat to privacy, we actually believe it is illegal, because last year Google entered into an agreement with the US Federal Trade Commission in which they said they would not engage in that kind of data sharing without the permission of their users." Google says its new policy will make it simpler for users to share information across services like Google Search, Gmail and Google Calendar. And it says the new policy will help personalize each user's experience. Over time, it says, users can expect to see better search results, fewer unwanted advertisements and more content targeted to their interests. But Marc Rotenberg says in return, people who choose to use Google will lose control over the information they share. "The type of information you might provide for an e-mail service, for example, such as your address book, which contains private information, is different from the type of information that you might provide for a social network service where people purposely make information publicly available to their friends." Mr. Rotenberg says these two kinds of services should be kept separate. "By trying to combine these two services, in our view, Google is actually undermining a very well established expectation of privacy, especially for popular Internet services like electronic mail." Critics also see a bigger problem with Google's new policy. The plan would not give users a choice to drop out of the data sharing. "In our view, if people want to make their potential information available, they certainly should have the right to do that. What we are objecting to is the effort by the company to take away from the users that choice that they should have. That just seems unfair." Google says it will not be collecting any more data than it does now. And it says users will still be able to control many privacy settings. For example, they can disable their search history and set Gmail chat to "off the record." European Union officials have asked the company to delay the new policy to make sure it would not violate any EU data protection laws. Marc Rotenberg thinks the Federal Trade Commission in Washington might also try to block the new policy. What seems to be a big problem with the new policy according to the critics? | [

mmlu_train_71393 | Robots have come a long way since 15th century. We've got robots to build cars, carry heavy things, work in dangerous places and explore planets. But things haven't stopped there. In 1986, Honda made a robot called ASIMO. And now, it has been developed greatly. Standing at 130cm and weighing 54kg. ASIMO is very much like a small astronaut wearing a bag on the back. And he can walk, flight, climb and run fast. Isn't it wonderful? The world's first robot teacher is Saya. With her human-like face, she can show expressions like happiness, surprise, sadness, dislike, fear and she can even smile or show anger at students, which look much like a real teacher's. To do this, her rubber skin is pulled from the back with motors inside. And her eyes and mouth have wires too. She can also say some simple words like "hello" or "thank you". In the UK, the development of robots is exciting. The mini-robots will send food, clean floors, collect and throw away waste. These robots can open doors by themselves and stop if anything or anyone is in the way. These mini-robots are very useful for controlling infection . Usually clean and dirty work is done by the same person, but here, you'll have robots that do"dirty work", like collecting dirty sheets, or taking away hospital waste; and you'll have robots that do"clean work", like bringing meals or clean sheets to patients. The robots have separate work so there's no way for infection, which is great. But of course, robots would not take the piece of humans, but would free up more time for nurses to be with patients.

But recently, some people have been much more concerned with how the grizzly bear and mountain lion can cross the road. Millions of animals die each year on US roads, the Federal Highway Administration reports. In fact, only about 80 ocelots , an endangered wild cat exist in the US today. The main reason? Road kill. "Ecopassages" may help animals cross the road without being hit by cars. They are paths both over and under roads. "These ecopassages can be extremely useful, so that wildlife can avoid human conflicts," said Jodi Hilty of the Wildlife Conservation Society. But do animals actually use the ecopassages? The answer is yes. Paul Beier of Northern Arizona University found foot marks left by mountain lions on an ecopassage that went under a highway. This showed that the lion used the passage. Builders of some ecopassages try to make them look like a natural part of an area by planting trees on and around them. Animals seem _ .

mmlu_train_67565 | Since the 1970s, scientists have been searching for ways to connect the brain with computers. Braincomputer interface(BCI) technology could help people with disabilities send commands to machines. Recently, two scientists, Jose Millan and Michele Tavella from the Federal Polytehnic School in Lausanne, Switzerland, show a small robotic wheelchair directed by a person's thoughts. In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts. "Our brain has billions of body cells . These send signals through the spinal cord to the body part to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the body part." Tavella says. "Our system allows disabled people to communicate with outer world and also to control machines." The scientists designed a special cap for the user. This head cover picks up the signals from the scalp and sends them to a computer. The computer finds meanings of the signals and commands the wheelchair with an engine. The wheelchair also has two cameras that tell objects in its path. They help the computer react to commands from the brain. Prof. Millan , the team leader, says scientists keep improving the computer software that finds meanings of brain signals and turns them into simple commands." The practical possibilities that BCI technology offers to disabled people can be grouped in two kinds: communication, and controlling objects. One example is this wheelchair." He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can get advantages from. And the other is sure that they can use the technology for long. Which of the following would be the best title for the text? | [

mmlu_train_46132 | Steve Jobs, Apple's chief executive, made his first public appearance since going on medical leave six weeks ago, taking the stage at a San Francisco media event to introduce the iPad 2, the second generation of the company's tablet computer. Thin but energetic, Mr. Jobs showed off a thinner iPad. " We've been working on this product for a while and I just didn't want to miss this day," he said. His absence has concerned investors, especially since the group has given no details of his condition. He was diagnosed with cancer in 2004 and had a liver transplant during almost six moths of medical leave in 2009. People close to him said last month his health had been changing. Apple's stock rose more than 2 percent in the minutes after Mr. Jobs began speaking, then gave up some of its gain as he detailed the iPad 2. The iPad 2 will go on sale in black and white versions in the US on March 11 and in 26 other countries, including the UK and Germany, on March 25. The table is Apple's biggest product launch since the iPhone three years ago, and is comparable to the iPhone as the most expected in Apple's history. Most of the improvements in the latest version had been expected, including front and rear-facing video, which allows video conferencing between iPads, Mac computers and the most recent iPhones and iPods, a larger speaker, a faster processor and other upgrades. The iPad 2 is one-third thinner than the original tablet and slightly lighter, with a 9.7-inch touchscreen. It can run movies, books, games and a complete range of applications. In the US it will work with AT&T and Verizon, the top two mobile carriers. The pricing will be the same to the 2010 iPad at its introduction, ranging from $499 to $829 in six models. But Apple dropped prices on the older iPad on Wednesday by $100 across the board. Apple has made the most of its year-long head start in tablets, selling 15,000,000 units of the older iPad last year and taking about 85 percent of the market. Forrester predicted that the iPad 2 would clain 80 percent of the US market this year, or 20,000,000 out of 24,000,000 total shipped. This prediction was based on both the technical improvements to the iPad 2, and the distribution difficulties and higher prices for Apple's rivals. Motorola, BlackBerry maker Research in Motion, Samsung and others have brought out competing tablets, many based on Google's Android software. Mr. Jobs said the rest of the field was still catching up with the first iPad and their markets for applications designed for tablets had, at best, 100 small programs. This compares with 65,000 on Apple's applications store. What makes Apple's tablets superior to the competing tablets of other companies? | [

mmlu_train_58588 | Noise pollution in cities is causing out health to suffer, according to the World Health Organization. Recently, researchers at the Free University of Brussels in Beigium have developed an applocation: NoiseTube. It allows everyone who downloads it the ability to measure the amount of noise they are exposed to by transforming their smart phone into a sound level meter. NoiseTube works by recording sound levels and GPS locations. Once launched the app shows decibel levels of green or red depending on the level of noise. That information is then sent to the NoiseTube server via the Internet where a "noise map" is produced and then made available to the user. Since its launch, the app has been popular with community groups who want to monitor their own noise levels. According to D'hondt of the Noise Tube project, these groups don't think that city produced noise maps give an adequate interpretation of the level of noise they're experiencing. City produced noise maps are based on statistical models involving very few actual measurements. NoiseTube on the other hand gives a detailed account of the level of noise experienced at a specific time and location. "Ten people walking the same area from 9 to 10 am every day for one week can make a valid and detailed map for an area of a couple of blocks," D'Hondt said. "It's reasonable effort by the community groups to produce these maps, and with it they can go to the authorities and have real evidence about what they're experiencing." So far these sorts of noise maps have been produced for a number of European cities. The app has been downloaded by 10,000 people with 2,700 people registered on the NoiseTube website.

mmlu_train_19276 | We know that sugary sodas aren't good for our bodies. Now it turns out that they may not be good for our minds, either. A new study of more than 260,000 people has found a link between sweetened soft-drinks and depression, and diet sodas may be making matters worse. Americans drink far more sodas than people in other countries-- as much as 170 liters per person per year. But the impact of this study isn't limited to the United States. "Sweetened drinks, coffee and tea are commonly consumed worldwide and have important physical consequences. And they may have important mental-health consequences as well," study author Dr Honglei Chen said in a statement. The study studied 263,925 people between the ages of 50 and 71. Researchers followed their consumption of drinks like soda, tea coffee, and other soft drinks from 1995 to 1996 and then. 10 years later, asked them if they had been diagnosed with depression since the year 2000. More than 11,3000 of them had. Participants who drank more than four servings of sodas per day were 30 percent more likely to develop depression than participants who did not drink sodas at all. People who stuck with fruit punch , had a 38 percent higher risk than people who didn't drink sweetened drinks. And all that extra sugar isn't the actual problem. Researchers say that the artificial sweetener _ may be to blame. The study found a link but could not surely determine whether sodas and other sweet soft drinks cause depression. Still, the results "are consistent with a small but growing body of evidence suggesting that artificially sweetened beverages may be linked to poor health outcomes." But there's a bright side for those who can't live without their daily sodas. Adults who drank coffee had a 10 percent lower risk of depression compared to people who didn't drink any coffee, according to the study. "Our research suggests that cutting out or down on sweetened diet drinks or replacing them with unsweetened coffee may naturally help lower your depression risk," said Chen.

Richard Eng from Beacon College, a former secondary school teacher, is often credited with being the first of Hong Kong's "star tutors". "In school all the teachers look the same, there's no excitement," he said. The celebrity tutor phenomenon is a result of the huge growth in outofschool tutoring in Asia. It is fuelled by highly pressured examination systems and ambitious parents wanting their children to secure places at top universities and highstatus secondary schools. In societies where success _ good exam results, parental anxiety converts into a "steady stream of revenue " for tutoring establishments, according to a study by the Asian Development Bank (ADB). The tutoring industry, or "shadow education" as the ADB calls it, has become very widespread in Asia, fed by the growth in universities and the rising proportion of school leavers aiming for university. Hong Kong University's professor Mark Bray, one of the authors of the ADB study, said a staggering 72% of finalyear school students in Hong Kong now go to private tutors. It's not just Hong Kong. Tutoring has "spread and intensified in Asia and become more commercialized," said Professor Bray. In South Korea, 90% of primary school children attend such classes. In China, New Oriental Education and Technology has grown to become one of the largest tutoring schools in Asia with around 2.4 million students this year.

My every waking hour was consumed by the project and although I imagined that I would feel happy after completing parts of the project, I was confused to find that instead, I was feeling rather depressed. I tried a range of methods to help cheer myself up. I had a relaxing bath, cooked a delicious meal to enjoy with my family and even watched a lighthearted movie, but _ . It was only when I turned to meditation for a solution that the answer came to me: turn to nature! The very next day, I grabbed my camera and a bottle of water and set off to spend a few hours walking in a nature reserve, even though it was pouring with rain. Within a couple of minutes I felt alive again. To be honest, I felt like a young school girl again and had to stop myself from hopping along the path singing, "I'm singing in the rain", a song I used to sing when I was a child. I think as adults we often try too hard to control our inner children and as a result we restrain our own spirits, which only leads to depression and stress. Interestingly, it has been shown that people who spend 40 minutes walking in a nature reserve have a drop in their blood pressure levels, but this does not happen when they spend a similar amount of time walking in a busy city centre.

mmlu_train_31340 | COLUMBUS, Ohio--The heart operation taking place in the pale-green operating room at the Ohio State University Medical Center was unusual. The patient, a 62-year-old man, was made to sleep, tied with blue drapes and lying face up on a narrow table. But no one was touching him. Instead, the operation was being performed by a robot, whose three metal arms went through pencil-sized holes in the man's chest. At the ends of the robot's arms were tiny metal fingers, with turning wrists, which held a tiny instrument, a light and a camera. The robot's arms and fingers were controlled by Dr. Randall K. Wolf, sitting at a computer in a corner of the operating room about 20 feet away. This sort of operation, heart surgeons say, is the start of what may be the biggest change in their profession since heart bypass surgery began nearly 30 years ago. "The reason we make cuts is that we have big hands," said Dr. Wolf, the director of the surgery at Ohio State. The robot's _ fingers, no longer than a nail on the small finger, at the end of the long sticks could work better. Eventually, surgeons believe, most heart surgery will be done by robots whose arms are put in through pencil-sized holes punched in patients' chests. Instead of directly staring into a patient's body, surgeons will view magnified images of the operation on computer screens. In theory, the doctor would not have to be in the same room, or even the same country, as the patient. The main idea of this passage is that heart surgery by robots _ . | [

mmlu_train_14292 | What happens inside the skull of a soccer player who repeatedly heads a soccer ball? That question motivate a challenging new study of the brains of experienced players that has caused discussion and debate among soccer players, and some anxiety among those of us with soccer-playing children. For the study, researchers at the Albert Einstein College of Medicine in New York selected 34 adults,men and women. All of the volunteers had played soccer since childhood and now competed year-round in adult soccer leagues. Each filled out a detailed questionnaire developed especially for this study to determine how many times they had headed a soccer ball in the previous year, as well as whether they had experienced any known concussions in the past. Then the players completed computerized tests of their memory and other learning skills and had their brains scanned, using a complicated new MRI technique which can find structural changes in the brain that can't be seen during most scans. According to the data they presented at a Radiological Society of North America meeting last month,the researchers found that the players who had headed the ball more than about 1,100 times in the previous 12 months showed significant loss of white matter in parts of their brains involved with memory,attention and the processing of visual information, compared with players who had headed the ball fewer times. This pattern of white matter loss is "similar to those seen in traumatic brain injury" , like that after a serious concussion, the researchers reported,even though only one of these players was reported to have ever experienced a conc ussion. The players who had headed the ball about 1,100 times or more in the past year were also generally worse at recalling lists of words read to them, forgetting or _ the words far more often than players who had headed the ball less. From the passage we can conclude that frequent heading may have _ . | [
