mmlu_train_15723 | Air traffic controllers in the US have been advised to take 26-minute naps , after a series of accidents involving workers falling asleep. Now the National Transportation Safety Board (NTSB) is calling for "controlled naps" during nightshifts . NTSB member Mark Rosekind said that a 26-minute nap would improve performance by 34%. He believes that beyond the aviation industry, other professions, such as motoring and machinery, also carry obvious risks. But other experts doubt whether 26 minutes is the appropriate napping time. It's a bit too long and risks you falling into a deep sleep, says Jim Horne, director of the Sleep Research Council. He said, "A nap of about 15 minutes is best; once you get beyond 20 minutes, you risk a deep sleep and you can be much more tired when you wake up. Therefore, we suggest that a nap be combined with a cup of coffee so that you can enjoy an effective sleep before the caffeine takes effect in 20 minutes. However, this method only works on those who have had a poor night's sleep. If you haven't had a sleep the night before, this method won't be enough to make you fresh." Health writer, Linda Wasmer Andrews, also believes that 26 minutes is too long. She says a nap between 10 and 20 minutes is enough, and the timing of the nap is also important. Putting your head down too early means your body may not be ready to sleep yet, but a nap that is too late in a day might make it harder to fall asleep. Early afternoon is often the best time, between l pm to 3pm, when people experience a post-lunch decrease in energy. According to Linda Wasmer Andrews, _ . | [

mmlu_train_56894 | An Apple employee is in trouble after the prototype of its top-secret iPhone5 was left in a bar. The as yet unreleased prototype was supposedly "misplaced" at Cava22 in San Francisco. Apple's security team was called in after reports that it had been sold over the internet for PS120. However, technology website Cnet.co.uk reports that the San Francisco Police Department said Apple had not reported the item as lost. Cava22 owner Jose Valle has said that neither the SFPD nor Apple have contacted him, although he does remember getting calls about a lost iPhone last month. It follows a very similar incident in April 2010 when a then-unreleased iPhone4 was left in a beer garden of a German bar in California by an Apple engineer. The lost iPhone4 was also sold over the internet to the technology blog, which paid PS3,000.

mmlu_train_31652 | Most of us would like to have glowing skin, especially as we get older. The good news is that you don't have to wait until summer to catch some sun rays. Scientists have found eating plenty of fruit and vegetables is by far the best way to achieve a healthy, golden glow. Dr. Ian Stephen said, "Most people think that the best way to improve their skin color is to get a suntan . But our research shows that eating lots of fruit and vegetables is actually more effective." The team first assessed the skin color of people in relation to their diet. Those who ate more fruit and vegetables a day were found to have a more golden, yellow skin color. Those with a healthy glow had a higher presence of carotenoids , which play a role in the immune system. Carotenoids are commonly found in fruit and vegetables such an yellow and red peppers, spinach, apricots and melons. The team then studied the relation between skin tone and attractiveness. They used specialist software to operate the skin color on the images of 51 faces to simulate more or less carotenoids and suntans. Participants were then asked to adjust the skin color to make the faces look as healthy as possible. Given the choice between skin color enhanced by suntans and skin color enhanced by carotenoids, people preferred the carotenoids skin color. The study shows that not only do people use skin color to judge how healthy other individuals are, but they are accurate when they make those judgments. While this study focus on Caucasian faces, it suggests this phenomenon may exist across cultures, since similar preferences for skin yellowness are found in an African population.

mmlu_train_17995 | It's a nightmare for Huazhong University of Science and Technology (HUST): within a week, two students committed suicide by jumping off dorm buildings. Officials from the university are reluctant to give interviews. "We had a hard time calming down students who were shocked at the suicides," said Zhang Jingyuan, head of HUST's center for research and guidance for students' development. "Media coverage may arouse some students' negative emotions again. Suicide can be contagious ," Zhang said. The university reacted promptly to the first suicide on October 23. Advisors and class leaders conducted dorm-to-dorm checks to find students suffering depression. Then psychologists offered one-on-one counseling to them. Notice boards publicizing tips for identifying peers' mental problems and offering help were set up in front of dorm buildings. Leaflets carrying similar information were handed out to each dorm. However, the second suicide came seven days later. Both students were described as men of few words. Their schoolmates didn't see anything to indicate suicide. Zhang revealed that the two students had been bothered by mental disorders. But the school didn't know this until the students' close friends outside school and their parents unveiled the truth after the suicides. According to Zhang, there are only three full-time counselors working in the university's counseling center for its 60,000 students. He complained: "It's unrealistic to rely only on counselors to detect students' mental problems." Some universities in the US may be able to offer solutions to Zhang's worries. They have established programs to train students to be the bridge between troubled friends and counselors. At Worcester Polytechnic Institute, at Worcester, Massachusetts, US, young people in the Student Support Network role play to learn how to detect SOS signals from their schoolmates. They also practice how to gently persuade emotionally troubled students to go for professional help. To develop such empathy , many universities in China have organized campus events to popularize knowledge about mental health. But these are not that attractive to students. Ke Juanjuan, 24, is pursuing a master's degree in English translation at HUST. Ke has found that few of her peers will pay attention to activities about mental health when they are not troubled by it. Rather than bombard students with the words "mental health", Ke suggested the school organize lectures and workshops concerning study, job-hunting and relationships. She explained: "Students care about these topics. They tend to have problems in these areas and may thus get stuck in depression. "By helping students better deal with these problems, the school can effectively prevent self-inflicted injury and suicide among students." Effective prevention comes from long-term education for life instead of temporary intervention to meet an emergency, said Hu Yi'an. Hu delivers a course of lectures on life and death at Guangzhou University. He worries that universities have paid little attention to education for life. "Education for life helps students respect and love life so they won't resort to ending their lives when they have difficulties," said Hu. According to Hu, the principles can be incorporated into everyday teaching. In which column of a newspaper would you most probably read this passage? | [

mmlu_train_55843 | WASHINGTON--Considering the serious warnings lately about Internet viruses, users may be encouraged to unplug their machines just to keep them safe. In reality, common sense and a few basic tips can keep Internet surfers secure. Antivirus software is a must, and it should be updated at least once a week to recognize newly released viruses. People with broadband Internet connections should also have a firewall. These protect the computer from attacks by hackers. Then it is time to think about computer habits. Unlike old viruses, which spread only through shared diskettes, the Internet brings viruses straight to the email-box. If email with attachment comes from an unknown sender, or unexpectedly from a known sender, it should not be opened. On receipt of an unexpected attachment from a friend, experts suggest a telephone call to make sure of the mail's source before opening.

mmlu_train_55963 | Which is sillier: denying we ever went to the moon or trying to convince the true non-believers? Once upon a time--July 20, 1969, to be specific - two men got out of their little spaceship and wandered around on the moon for a while. Ten more men walked on the moon over the next three and a half years. The end. Unfortunately, not quite. A fair number of Americans think that this whole business of moon landings really is a fairy tale. They believe that the landings were a big hoax staged in the Mojave Desert, to convince everyone that U.S. technology was the "best" in the whole wide world. Which is the harder thing to do: Send men to the moon or make believe we did? The fact is that the physics behind sending people to the moon is simple. You can do it with computers whose entire memory capacities can now fit on chips the size of postage stamps and that cost about as much as, well, a postage stamp. I know you can because we did. However, last fall NASA considered spending $15,000 on a public-relations campaign to convince the unimpressed that Americans had in fact gone to the moon. That idea was mostly a reaction to a Fox television program, first aired in February 2001, that claimed to expose the hoax. The show's creator is a publicity hound who has lived up to the name in more ways than one by hounding Buzz Aldrin, the second man on the moon. Mr. X (as I will call him, thereby denying him the joyous sight of his name in print) recently followed Buzz Aldrin around and called him "a thief, liar and coward" until the 72-year-old astronaut finally lost it and hit the 37-year-old Mr. X in the face. Anyway, NASA's publicity campaign began to slow down. The nonbelievers took the campaign as NASA's effort to hide something while the believers said that $15,000 to convince people that the world was round -- I mean, that we had gone to the moon -- was simply a waste of money. (Actually, the $15,000 was supposed to pay for an article by James E. Oberg, an astronomy writer who, with Aldrin, has contributed to Scientific American.) If NASA's not paying Oberg, perhaps it could put the money to good use by hiring two big guys to drag Neil Armstrong out of the house. Armstrong is an extremely private man, but he is also the first man on the moon, so maybe he has a duty to be a bit more outspoken about the experience. Or NASA could just buy Aldrin a commemorate plaque for his recent touch on the face of Mr. X. The believers think that NASA's publicity campaign is _ . | [

It is obvious that if students value highly their test scores,then a great amount of their self-respect is put in the number.Students who perform poorly on the exam are left feeling that it is all over.The low test score,they think,will make it impossible for them to get into a good college.And without a degree from a _ ,they fear that many of life's doors will remain forever closed. According to a study done in the 1990s,the SAT is only a reliable indicator of a student's future performance in most cases.Interestingly,it becomes much more accurate when it is set together with other indicators-like a student's high school grades.Even if standardized tests like the SAT could show a student's academic proficiency ,they will never be able to test things like confidence,efforts and willpower,and are unable to give us the full picture of a student's potentialities .This is not to suggest that we should stop using SAT scores in our college admission process.The SAT is an excellent test in many ways,and the score is still a useful means of testing students.However,it should be only one of many methods used.

mmlu_train_65829 | The Lionfish Invasion! Lionfish are popular saltwater aquarium fish all over the world, especially in the United States. Nowadays, they also live in Atlantic waters off the East Coast of the United States. These lionfish are what scientists call an invasive species or an "alien invader." Local divers off the coast of North Carolina were not expecting to see what they found one day in August 2002--the beautiful lionfish, common to the warm waters of the western Pacific, but unknown of the Carolina coast. They provided the first solid evidence that lionfish were in the Atlantic. A year later, scientists documented 19 lionfish sightings at eight locations along the North Carolina continental shelf. Then, lionfish were observed off the coasts of Florida, Georgia, and South Carolina, and even as far north as Long Island, New York! Between 2000 and 2003, lionfish sightings were reported at 16 different shipwrecks and natural hard bottom locations. During a summer 2004 research expedition, NOAA(The National Oceanic and Atmospheric Administration) scientists collected 155 lionfish at 19 different locations off the North Carolina coast alone. The jump in numbers and distributions over such a short time strongly indicates that the lionfish is reproducing in the Atlantic Ocean. If this is true, it's the first time that a western Pacific fish has populated the U.S. Atlantic coast. These lionfish were likely released on purpose when people no longer wanted them! The swift and warm Gulf Stream, which transported the floating lionfish eggs from Florida northward, helped the lionfish's Atlantic journey. In Florida waters and along the continental shelf near the Gulf Stream the temperatures are very similar to the lionfish's native waters. However, from north Florida upward, the waters along the coastline are too cold in the winter for lionfish to survive. Scientists expect them to survive the winter only at water depths greater than 120ft because this is where the Gulf Stream has influence all year long. Very importantly, the types of predators and competitors present in the Atlantic are very different from the native range of the lionfish. Generally, the lionfish have not been found to endanger marine ecosystems because they were not likely to survive long. What is the author's attitude towards the lionfish invasion? | [

mmlu_train_62964 | Yawning sends out certain messages -either "Oh,this movie is so boring" or "I probably need to get some sleep". But did you know that a yawn can also help your brain to cool down when it is overheated? A new study, led by a research team at Princeton University, has indicated that yawning could be the brain's natural way of regulating temperature. People yawn more often when the temperature outdoors is lower than their body temperature but are less likely to yawn when it is hotter outdoors, according to Sciencedaily. com. The research team did an experiment on 160 people, 80 in summer and 80 in winter, to examine how often they yawned at different air temperatures. The study found that people yawned more often in winter than in summer. Scientists say that when the air temperature is lower outside the body, there is heat exchange between the overheated brain and the cool air. But when the air temperature is higher than or equal to the body, people are less likely to yawn because the hot air they breathe in will make the brain even hotter. When people yawn, their jaw is also stretched,which increases blood flow and may also help cool the brain The study showed that the amount someone yawned could be related to the amount of time they spent outside. The longer they spent outside in summer, the less they yawned. Nearly 40 percent of participants yawned within their first five minutes outside, but after that the percentage was reduced to less than 10 percent. However, the result was the opposite in winter. The number of people who yawned increased when they spent more than five minutes outdoors. But the change was only slight compared to summertime. According to Gallup, this is the first report to show that yawning frequencies change depending on season. This could help us to understand better the way our brains work. It may also help us understand the reason why frequent yawning can sometimes be a sign of brain disease. What could be the best title for the text? | [

mmlu_train_55321 | Every so often, birds, just like humans, do what it takes to feel really, really good. The bird version is to sit on an anthill so that hundreds of ants climb all over their bodies, or even better, some birds pick up mouthfuls of pressed ants and rub themselves all over. Afterwards, the birds either eat the ants or set them free. Scientists call this "anting." It's a common bird practice, and is especially done by the smarter birds. Ravens do it. Magpies do it. However, birds aren't the only animals that use anting --- squirrels, cats, and hedgehogs have all been observed doing the same sort of thing! Why birds "ant" is something of a mystery, but one thought is acceptable. Ants have defensive secretions , chemical weapons they use to fight off other insects and bacteria. So pressed ants help the birds drive the insects away. Similarly, if you cover your body with them, you can move through the forest without worrying about being bitten by insects. Plus, ants are cheap. They are around. However, we have a better explanation. Birds "ant" a lot in spring and summer. For many birds, that's the season for birds to change feathers. So maybe ant secretions are like bath oil; they comfort the skin during feather replacement. A British scientist once declared "the purpose of anting the stimulation and comfort of the body," and that the general effect "is similar to that gained by man from the use of outside stimulants, and perhaps also smoking." And like cigarettes, anting can become a habit. Another study compares anting to "the human habits of smoking and drug taking," and says, "it is enjoyed for the feeling of excitement it results in. So once experienced, it is difficult to stop." That's why you often see mother birds shouting at their babies who come near their first anthill. "Stay away from there, child... Don't touch those ants!" they cry. I don't speak Raven. Or Magpie. But I have been a parent. So some things I know. It is implied in the text that _ . | [

mmlu_train_5956 | Without most people realizing it, there has been a revolution in office work over the last ten years. Before that time, large computers were only used by large, rich companies that could afford the investment. With the advancement of technology, small computers have come onto the market, which are capable of doing the work that used to be done by much larger and expensive computers, so now most smaller companies can use them. The main development in small computers has been in the field of word processors , or WPS as they are often called. 40% of British offices are now estimated to have a word processor and this percentage is growing fast. There are many advantages in using a word processor for both secretary and manager. The secretary is freed from a lot of daily work, such as re-typing letters and storing papers. He or she can use this time to do other more interesting work for the boss. From a manager's point of view, secretarial time is being made better use of and money can be saved by doing daily jobs automatically outside office hours. But is it all good? If a lot of daily secretarial work can be done automatically, surely this will mean that fewer secretaries will be needed. Another worry is the increasing medical problems related to work with visual display units . The case of a slow loss of sight among people using word processors seems to have risen greatly.

While the subjects--usually students--sleep, special machines record their brain waves and eye movements as well as the body movements that signal the end of a dream. Surprisingly, all subjects sleep soundly. Observers report that a person usually fidgets before a dream. Once the dream has started, his body relaxes and his eyes become more active, as if the curtain had gone up on a show. As soon as the machine shows that the dream is over, a buzzer wakens the sleeper. He sits up, records his dream, and goes back to sleep--perhaps to dream some more. Researchers have found that if the dreamer is wakened immediately after his dream, he can usually recall the entire dream. If he is allowed to sleep even five more minutes, his memory of the dream will have disappeared. According to the passage, researchers at the University of Chicago are studying _ . | [

mmlu_train_27870 | The new world of today introduced new threats that were not known in the previous generations: Internet predators . Often we do a lot of our researching, shopping, talking; just about everything online nowadays. New advancements in revolution comes along with the unwanted attackers. There are people out there who gain pleasure from, interrupting and taking from our peaceful lives what's not rightfully theirs. But like with everything, there are indeed counteractive measures that can be set in place to fend off these predators from such damage. I'd like to introduce the Guardian Eye. Within this program is a complex program which has several functions to create a safe atmosphere for whomever uses the computer, It has the ability to track and log every key stroke, every website that has ever been accessed, takes screenshots of web pages, blocks web pages according to content and even sends you messages via email once conspicuous activity has been reported and logged. Just think, you or child could be browsing and searching through the Internet and inappropriate content pops up with several different windows. You try to click out of the windows but you accidentally click one which releases spyware, infecting your computer. Guardian Eye blocks unwanted content from popping up or appearing to the users, which I thought was extremely convenient. In this way there is not even the slightest temptation. This product helps prevent damage from being done to your computer and worse, your identity. It's quite the product and it offers a little version so you may try it out first. If you'd like the full package, it's a once time fee 39.99 and can be installed on unlimited computers for your convenience. It's a nice deal and I'm considering getting it again considering I do a lot of writing on various websites myself. In what way is Guardian Eye most useful to kids? | [

mmlu_train_30361 | Does solving a math problem give you a headache? Doyou feel nervous when you sit a math exam? For most students, math can be tough but scientists have proved that math problems can actually trigger physical pain. Scientists came to his conclusion with an in-depth experiment, which was published in the Public Library of Science One journal. They began by finding out how much participants fearmath. Those involved were asked a series of questions such as how they feel when they receive amathtextbook orwhenthey walkinto amathlesson. Based on their answers, participants were divided into groups. One group was made up of peoplewhowere particularly afraid ofmath and participantsinthe other group weremore comfortablewiththesubject. Both groups were then given either math tasks or word tasks. When a math task was going to come next, a yellow circle would appear but when a word task was soon to come, a blue squarewould beshown. Using a brain-scan machine, scientists noticed that whenever people from Group One saw ayellow circle, their brain would respond in a way similar to when their bodyis feeling pain. It waslike the pain they would fee, for example, if they burnt their hand on a hot stove. But theyreactedlessstrongly whenthey knew that they would befaced with awordtask. However, scientistssaw no strong brainresponsefrom peopleinthesecond group. Math can be difficult, and for those with high levels of mathematics-anxiety (HMA), math is associated with tension, apprehension and fear. "When you are really thinking about the math problems, your mind is racing and you are worrying about all the things that could go wrong," explained Ian Lyons from University of Chicago, US, leader of the study. "The higher a person's anxiety of a maths task, the more he activated brain regions associated with threat detection, andthe experience of pain." More interestingly, the brain activity disappeared when participants actually started dealingwiththemathtasks. "This means that it'snot that mathitself hurts; rather, the anticipation ofmathis painful,"Lyonssaid.

mmlu_train_64818 | The Cuban iguana is a species of lizard of the iguana family. It is the largest of the West Indian rock iguanas, one of the most endangered groups of lizards. This species with red eyes and a thick tail is one of the largest lizards in the Caribbean. The Cuban iguana is mainly _ : 95% of its diet consists of the leaves, flowers and fruits from as many as 30 plant species, including the seaside rock bush and various grasses. However, Cuban iguanas occasionally eat animal matter, and individuals have been watched eating the dead flesh of birds, fish and crabs. The researchers wrote that quite a few people on Isla Magueyes could have caused this incident. The Cuban iguana is living throughout the rocky southern coastal areas of mainland Cuba and its surrounding islands with a wild population growing rapidly on Isla Magueyes, Puerto Rico. It is also found on the Cayman Islands of Little Cayman and Cayman Brac, where a separate subspecies occurs. Females guard their nest sites and often nest in sites half destroyed by Cuban crocodiles. To avoid the attack from them, the Cuban iguana often makes its home within or near prickly-pear cacti . In general the species is decreasing, more quickly on the mainland than on the outlying islands. One of the reasons for their decrease is habitat destruction caused by the over consuming of farm animals, housing development, and the building of tourist resorts on the beaches where the animals prefer to build their nests. Although the wild population is decreasing, the numbers of iguanas have been sharply increased as a result of captive-breeding and other protection programs.

mmlu_train_41161 | Almost five years ago, I announce to my loved ones I was to become a Mrs Naturally. I then began to wonder about the perfect wedding dress, hoping that it would fit me. Even at the age of 22, I had gone through my share of dieting. I am an emotional eater and I knew that at 5 feet 5 inches tall and weighing 180 pounds, I wasn't at my healthiest. My mother had been doing Weight Watchers for some time and was rapidly seeing results. I took my mother's advice about Weight Watchers. She shared her books with me and explained the program: estimate your daily point target based on your weight and other factors, write down everything you eat and move! The longer I stuck to it, the more I noticed a difference in the way I enjoyed food. I soon began to like eating fruit and vegetables for snacks instead of chocolate bars and chips. My mother and I went on walks together and kept each other in check. Unsurprisingly, I lost twenty pounds soon and looked amazing in my wedding dress. I bought healthy food instead of ice creams and faithfully kept a food journal. I exercised on my Wii Fit and took evening walks. Since I had a hard time finding something healthy to eat, I bought a Weight Watchers cookbook and used it to prepare our meals. I used small plates and bowls to trick myself into believing there was more food than the serving size. Now I'm 28 and weigh 120 pounds, but I still need to lose some weight.

By the time you are through the security doors and into the emergency area, that sample could have been sent through to the lab by vacuum tube and analysed by a machine which automatically feeds a preparative result into the clinical database. Less than a minute after the sample is processed, the doctors can see the results through the monitors beside every position in the emergency suites. As you are being wheeled in, you may notice cameras in the ceiling. The hospital has spent $4 million on its camera security system to protect staff and patients.

mmlu_train_38379 | When it comes to problem solving, many of us have heard of the skills of the crow in Aesop's Fables (<<>> ). In the story, a thirsty crow comes across a bottle of water, but the water level is out of its reach. The bird then drops small stones into it until the water level rises enough for the bird to drink. "Oh, it's just a fable," you may think. After all, it's hard to imagine birds knowing about "problem solving". But new research has found that crows' brains may sometimes be better than those of 6-year-old children. In a recent experiment, US scientist Corina Logan and her team caught six crows to test them. There were two tubes of water, one wide and the other narrow . Each crow was given four stones, enough to help them get the water in the narrow tube, but not the wide one. Surprisingly, the crows dropped all or most of the stones into the narrower tube and got the food reward! They had found out the cause-and-effect relationship.Using such brains, crows are making their lives easier. For example, some crows in cities have learned to use road traffic for breaking nuts, National Geographic News reported. But how are their wits compared to humans'? Logan's team did another experiment, this time on both crows and children. Here, the crows and children had to choose between two sets of tubes. With the red set, when they dropped a stone into a wide tube, the water level raised in a connected narrow tube that contained food. The blue set of tubes, however, had no connection between them. So dropping a stone in the wide tube did not cause the water level to rise in the narrow tube. Children aged 7 to 10 were able to learn the rule. Children aged 4 to 6, however, failed. Five of the six crows failed the test. But Kitty, a 6-month-old crow, passed it. She put all or most of the stones into the red tube. So, could a bird be more clever than a kindergartner? Don't be too quick to say no. Why is Aesop's Fables mentioned in the beginning of the article? | [

mmlu_train_13637 | Fat on human body is distributed in two different ways. Some fat people have a large chest and no waistline , looking rather like apples. Others are fatter below the waist, looking more like pears. Doctors in Cambridge, England have been examining the relationship between health and fat distribution. They find that the pear-shaped fat people have fewer problems than the apple-shaped people. What seems to be most important is not just how much fat you have but where you have it. The doctors measured the apple-shaped women and pear-shaped women and examined them with X-ray scanners (X). Human beings have two types of fat, one is outside fat that is the fat below the skin and the other is inside fat that lies inside the body. Using the X-ray scanners, the doctors found that the "apples" have a large amount of inside fat. If this inside fat is much more than outside fat, it will probably cause health problems such as obesity . The best treatment for obesity is to reduce the inside fat. But unfortunately diet treatment simply makes an apple-shaped person into a smaller apple and a pear-shaped person into a smaller pear. At the moment there is no effective way of reducing the inside fat. The basic reason why some people suffer from obesity is that | [

The Apple Watch, according to CNN, is "a simple rectangular shape with a range of stylish and useful wristbands." "The style is classic... in those respects it's up there with the top quality Swiss watches," commented the news outlet. The watch will be available in nine places, including the US, the UK and China, from April 24. The starting price is $349 (2,186 yuan). With six different designs and 30 or so wristbands, the gadget "sets the standard for smartwatches, in style," agreed The Brisbane Times,"but more importantly, in functionality ." "With the built-in speaker and microphone, you can receive calls on your watch. I have been wanting to do this since I was 5 years old," said Apple's chief executive Tim Cook. In fact, anything you can do on the iPhone is there on the watch - e-mails, text messages, airline boarding services, and directions from Apple Maps. Using a home security app, you can keep an eye on your home from afar, or even open a locked door. There are some features that have made Cook sure the watch is "our most personal device yet; a new chapter in the way we relate to technology". According to NPR, the watch taps you on the wrist to draw your attention to a message or a calendar reminder, and it can send a tap on the wrist to another Apple Watch wearer. However, the watch can also do things that are just plain fun. You can send a real-time display of your heartbeat to another Apple Watch to "let someone know you are thinking about them." Patrick Moorhead, a leading technology analyst in the US, described the tech company as "a master in the art of persuasion". "The secret weapon is the ability to message each other by tapping on the watch," he told The Associated Press. "I think people, particularly kids, are going to go nuts over that." So far, though, the most impressive part of this new device is "the monitoring of the wearer's health and fitness," said AFP.

For about 300 days, she stays with the eggs, cleans them and protects them. She does not leave to feed. However, this animal mom dies as soon as the eggs are hatched . Crocodiles A crocodile mother puts a lot of time and effort into raising her babies. She starts by building a nest , which she guards for over two months! When the eggs are ready to hatch, the young crocs call out to their mother, who digs them out and helps them hatch. She then carries them in her mouth down to the water, where she will guard them for several more weeks or months until they learn to hunt on their own. Bats Bats become moms by hanging head up in a cave, giving birth. Catching the youngster before it can fall to the ground below, she puts it in a pouch . Bat moms may carry babies with them when feeding for the first few days. As the little bats get bigger and heavier, moms help them hang on the wall of their caves and return often to feed them.

The hairless baby climbs into its mother's pouch and lives there for another five months. When the little koala is between five and eight months old, it leaves the pouch for short periods of time but returns for safety. Once it is too big to return to the pouch, it will climb onto its mother's back and ride there until it is about 12 months old. How long does the bat mom help to feed her babies? | [

mmlu_train_23567 | Butterflies are some of the most fascinating and beautiful insects in the world. Adult butterflies will live about 2 to 4 weeks. They use their senses of sight, touch, hearing, smell, and taste to survive in the world, find food and mates, lay eggs in an appropriate place, migrate, and avoid hungry enemies. Butterflies have large compound eyes , which allow them to see in all directions without turning their heads. Like most insects, butterflies are very nearsighted, so they are more attracted to a sea of flowers than individual plants. Butterflies do not "see" colors such as red, green, and yellow, but they can sense sunlight, which indicates the direction the sun is shining, as well as ultraviolet light , which is present on many flowers and guides butterflies to honey sources. Butterflies have a very well-developed sense of smell, but it is not in their nose, since they don't have one. Sense receptors are located in their antennae , feet, and many other parts of the body. They can help butterflies find their favorite flower honey food, and mates. Butterflies' feet have sense organs that can taste the sugar in flower honey, letting the butterflies know if something is good to eat or not. Some females also carefully choose host plants by tasting to find appropriate places to lay their eggs. Adult butterflies feed their babies using a long tube. Butterflies force blood into the tube to straighten it out, allowing them to feed. Butterflies get all their food from this tube. Butterflies don't have ears. Instead they "hear" sounds through their wings by sensing changes in sound vibrations . Butterflies may possess senses we don't even know about yet, because their body structure is very different from ours, and therefore difficult to understand, when observed through our own human senses.

mmlu_train_17582 | Doctors have a new weapon in the battle against obesity -- a talking plate that tells people not to eat too quickly. The Mandometer monitors the amount of food leaving the plate, and tells users, "Please eat more slowly." The PS1,500 Swedish device is to be used in a National Health Service plan to help hundreds of obese families lose weight. It comes in two parts -- a scale placed under the plate and a small computer screen showing a graphic of the food gradually disappearing as the user eats. A red line on the screen shows the user's eating speed, while a blue line shows a healthy rate. If the user eats too fast, the red line angles away from the blue one, warning him or her to _ . If the lines deviate too much, the computer voice comes on, and the screen flashes the message "Are you feeling full yet?" to remind users to think about whether they have had enough. Britain has an increasingly serious obesity problem, with one in four adults and one in seven children classed as obese. After a recent trial using the device, experts believe teaching obese people to eat more slowly will help them know when they are full. Around 600 families with at least one obese parent and child (aged five or older) were targeted in the project by Bristol University, along with GPs and nurses. Professor Julian Hamilton-Shield, who is leading the plan, says obese children and adolescents using the Mandometer ate from 12 to 15 percent less per meal at the end of the 12-month trial. Six months after they stopped using the device they still ate less, and continued to lose weight. "It will be a powerful tool to help families retrain their eating habits," he says. What can we infer from the text? | [

mmlu_train_20091 | Most people know Alexander Graham Bell invented the telephone. But not many know about another talking device (equipment) he invented just four years later, in 1880. He called the device the photophone. "Photophone" comes form the Greek words for "light" and "sound". The photophone did not use electricity to carry sound over wires between two people. _ . Instead, the photophone used a beam of sunlight traveling through the air. With his invention, Bell could actually transmit human speech on a beam of light. To do so, he spoke close to a thin mirror that was reflecting sunlight. The vibrations of his voice caused the mirror to vibrate, and the vibrating mirror caused the light to vibrate. The vibrating light hit a light-sensitive cell in a receiver placed some distance away. The cell changed the light patterns into electrical signals. Earphones changed the signals back into sounds. Bell believed that his idea of talking on a beam of light would prove to be important. He often called the photophone his greatest invention. Even though the photophone depended on a source of energy that was not constant--the sun--Bell wasn't a bit discouraged. He felt sure that people would one day talk using beams of light. Two much more recent developments made Bell's dream come true. In 1960, a scientist built the laser. A laser produces a highly concentrated beam of light. Shortly afterward, other scientists developed a new kind of optical fiber. The optical fiber is a glass thread. The new fiber could carry light beams long distances--as far as several miles.

mmlu_train_59465 | One in five people carry a 'smart gene' variant linked to long lifespan, bigger forebrains and enhanced mental ability, researchers have found. 'We've known for a long time that people lose cognitive abilities as they age, but now we're beginning to understand that factors like KLOTHO can give people a boost in aging. Genetic variation in KLOTHO could help us predict brain health and find ways to protect people from the diseases that happen to us as we grow old, like Alzheimer's disease ," said senior author, Dena Dubal of University of California. The KLOTHO gene affects a protein found in the kidneys and the brain that regulates many different body processes. About one in five people carry a single copy of the varian, known as KL-VS,which boosts levels of the protein and is associated with a longer lifespan and improved heart and kidney function. A small minority, 3% of the population, has two copies, which is linked to a shorter lifespan. In the new study scientists scanned the brains of 422 men and women aged 53 and over who were also tested for the KLOTHO gene. They found that participants with a single copy of the gene variant also had a larger brain region known as RDLPFC, which is especially likely to shrink with age. Loss of neurons in this area may be one reason why older people are sometimes easily distracted and find it difficult to do more than one task at the same time. Researcher Dr Jennifer Yokoyama said, " The brain region enhanced by genetic variation in KLOTHO is vulnerable in aging and some mental disease. In this case, bigger size means better function. It will be important to determine whether the structure increase associated with carrying one copy of KL-VS can _ the cognitive shortage caused by disease."[:] People who have one copy of a variant KL-VS tend to live longer and have lower chances of suffering a stroke ,whereas people who have two copies may live shorter lives and have a higher risk of stroke. The reason why older people's attention is easily distracted may be that _ . | [

mmlu_train_48415 | They may be just passing your office, computer bag slung over one shoulder. Or they may be sitting in a car outside it, causally tapping away at a laptop. They look like innocent passers-by. In fact, they are stealing your corporate secrets. Drive-by hacking is the trendy term given to the practice of breaking into wireless computer networks from outside the buildings that house them. A recent study in the UK, sponsored by RSA Data Security, found that two-thirds of organizations with wireless networks were risking their data in this way. Security experts patrolled several streets in the City of London seeking evidence of wireless networks in operation. Of 124 that they identified, 83 were sending data without encrypting them. Such data could readily be picked up by a passer-by armed only with a portable computer, a wireless modem and a few pieces of software that can be freely downloaded from the Internet. The data could include sensitive company documents containing valuable information. Or they could be e-mail identities and passwords that could be used by hackers to log into corporate networks as if they were legal users. Most companies using wireless networking technology do not take even the simplest of measures to protect their data. Nearly all wireless network technology comes with some basic security features that need only to be activated in order to give a minimum level of security, for example, by encrypting the data being passed over the network. Raymon Kruck, business development manager at Check Point Software, a security technology specialist, believes this could be partly a psychological problem. People see the solid walls of their building as safeguards and forget that wireless networks can extend up to 200 meters beyond physical walls. Companies without any security at all on their wireless networks make it ridiculously easy for hackers to break in. Switching on the security that comes with the network technology should be automatic. Then there are other basic steps a company can take, says Mr. Kruck, such as changing the passwords on the network from the default setting. Companies can also install firewalls, which form a barrier between the internal network and the public Internet. They should also check their computer records regularly to spot any abnormal activity, which might betray the presence of a hacker. Most wireless network technology has _ . | [

mmlu_train_32264 | During the 19th century, scientists found that when certain parts of the brain of a person were hurt, he would lose the power of doing certain things. And so people thought that each part of the brain does a different job. But modern research has discovered that this is not so, for it is not easy to show exactly what each part of the brain does. In the past fifty years there has been a great increase in the amount or research done on the brain. Scientists have found out that the way the brain works is not so simple as people in general may think. Chemists tell us that about 100,000 chemical changes take place in the brain every second. Some recent researches also suggest that we can remember everything that happened to us. We may not be able to think of the things we have heard and seen but it is kept there in the store-house of the human mind. Earlier scientists thought that the power of one's brain got weaker and weaker as one grows older. But it is plenty of exercise, it keeps its power. It is now thought that is not true. As long as the brain is given plenty of exercise, it keeps its power. It has proved that an old person who has always been active in the mind has a quicker mind than a young person who has done physical work without using much of his brain.
