mmlu_train_12472 | Most evenings, before watching late-night comedy or reading emails on his phone, Matt Nicoletti puts on a pair of orange-colored glasses that he bought for $8 on the Internet. "My girlfriend thinks I look ridiculous in them," he said. But Mr.Nicoletti, a 30-year-old consultant in Denver, insists that the glasses, which can block certain wavelengths of light emitted by electronic screens, make it easier to sleep. Studies have shown that such light, especially from the blue part of the spectrum , _ the body's production of melatonin ,which helps people fall asleep. Options are growing for blocking blue light, though experts caution that few have been adequately tested for effectiveness and the best solution remains avoiding brightly lit electronics at night. A Swiss study of 13 teenage boys, published in August inThe Journal of Adolescent Healthshowed that when the boys wore orange-colored glasses, also known as 'blue blockers' and shown to prevent melatonin, in the evening for a week, they felt "significantly more sleepy" than when they wore clear glasses.The boys looked at their screens, as teenagers tend to do, for at least a few hours on average before going to bed, and were monitored in the lab. Older adults may be less affected by blue light, experts say, but blue light remains a problem for most people, and an earlier study of 20 adults aged 18 to 68 found that those who wore orange-colored glasses for three hours before bed improved their sleep quality considerably relative to a control group that wore yellow-colored lenses, which blocked only ultraviolet light. LEDs used in devices such as smart phones, tablets and televisions tend to emit more blue light than incandescent products . LEDs are also increasingly popular as room lights, but "warm white" bulbs, with less blue, tend to be a better choice than "cool white" for nighttime use. The lighting company Philips also makes a reduced-blue LED bulb, meant to be used before bedtime."In theory, anything that will decrease that blue light exposure at night will be helpful." said Christopher Colwell, a scientist at the UCLA, "I know some gainers who swear by those orange-colored glasses." But orange glasses are not a panacea . Dr. Skene said."It isn't just getting rid of the blue and everything's fine," she said. The intensity of light, in addition to color, can affect sleep, she said, and not all brands of orange-colored glasses have undergone enough independent testing for their ability to aid sleep. During the daytime, experts say, exposure to blue light is good. Best of all is sunlight, which contains many different wavelengths of light."That's what our brain knows," said Kenneth P.Wright Jr., director of the sleep and chronobiology lab at the University of Colorado, Boulder. A 2013 study he led, published in the journalCurrent Biology, showed just how different things can be without nighttime lights. After participants had camped in the mountains for a week, their bodies began to prepare for sleep about two hours earlier than normal. Short of cutting out all evening electronics, experts say, it's advisable to use a small screen rather than a large one; dim the screen and keep it as far away from the eyes as possible; and reduce the amount of time spent reading the device. "If you can look at the iPhone for 10 minutes rather than three hours, that makes a lot of difference," Dr.Skene said. Which of the following statements is true? | [
"The older a person is, the less he or she will be affected by blue light.",
"The exposure to the blue light does nothing but harm to the human body.",

mmlu_train_52801 | If drinking coffee or tea has become part of your daily routine, you might wonder what it's doing to your long-term heart health. New research from Arteriosclerosis, Thrombosis, and Vascular Biology, a journal of the American Heart Association, found that high tea consumption and proper coffee consumption may be associated with decreased rates of death from coronary heart disease ( CHD) . The study followed more than 37,000 tea and coffee drinkers over 13 years. Participants completed food recalls to document their typical intake of tea and coffee, and were divided into groups that ranged from light to heavy consumption. Researchers accounted for variables such as health histories, height, weight, and waist circumference and recorded the number of deaths from cardiovascular disease and stroke during the study period. Overall results showed that consuming more than six cups of tea per day was associated with a 36% lower risk of death from heart disease compared to consuming less than one cup of tea per day. There appeared to be no such protective effect of tea-drinking at any amount for risk of death from stroke. Among coffee drinkers, more proper consumption levels (2-3 cups per day) were associated with the greatest risk reduction for death from heart disease (21% ) compared to drinking less than one cup of coffee per day. Researchers acknowledged certain inconclusive variables within their findings. For example, the difference between decaffeinated and regular coffee could not be accurately accounted for, nor could specific recommendations be made for type of tea, though due to its popularity in the Netherlands where the study took place, researchers assumed most tea consumption to be black tea. Furthermore, researchers found that tea and coffee drinkers had opposite lifestyles, with tea drinkers tending to engage in healthy lifestyle habits and coffee drinkers being more likely to eat less healthy and smoke. It was difficult to say with certainty what impact these other lifestyle variables may have contributed to the overall results. Which of the following variables haven't been considered? | [

mmlu_train_28039 | Jack Andraka from Maryland won the grand prize at the 2012 Intel International Science and Engineering Fair. It is the largest high school science competition in the world. The Maryland teenager is the youngest winner of the $75,000 prize. He was chosen from among 1,500 students in 70 countries. Jack Andraka invented a test for pancreatic cancer . He started to learn it after losing a close family friend to the disease. "I went on the Internet and I found that 85%of all pancreatic cancers are found late, when someone has less than 2% chance of survival , " he says, "and I was thinking,' That's not right. We should be able to do something.'" He found that early discovery is important to increasing the chances of surviving the disease. The Maryland teenager asked to work in a laboratory at Johns Hopkins University in Baltimore and was allowed. There he developed a simple paper test, which can recognize the disease in a single drop of blood. His test has proved correct 90% of the time. It also is 100 times more sensitive than other tests. "It costs 3 cents per test, and then it takes only 5 minutes to run," he said. Jack's success wouldn't have been possible without Anirban Maitra, a professor at Johns Hopkins. He was the only person among the 200 researchers Jack wrote to who showed interest in his project. "I was very surprised that this was a 15-year-old who was writing this. I wanted to meet this clever young man and see what he wanted to talk about and so I called him over for an interview . " Jack worked in Professor Maitra's laboratory, completing his project in 7 months. The government has given the Maryland teenager patent rights to the pancreatic cancer test. He is now talking with companies about developing the test into a simple product. Whatever happens, the professor believes Jack Andraka's name is one we will be hearing again over the next 10 to 20 years. Jack Andraka's research on pancreatic cancer _ . | [

mmlu_train_58491 | Classical philosophers called humans "the rational animal". Clearly, they never looked closely at ants. A new study suggests that ant colonies avoid irrational decisions that people and other animals often make. Consider the following scenario: You want to buy a house with a big kitchen and a big yard, but there are only two homes on the market---one with a big kitchen and a small yard and the other with a small kitchen and a big yard. Studies show you'd be about 50% likely to choose either house---and either one would be a rational choice. But now, a new home comes on the market, this one with a large kitchen and no yard. This time, studies show, you'll make an irrational decision: Even though nothing has changed with the first two houses, you'll now favor the house with the big kitchen and small yard over the one with the small kitchen and big yard. Overall, scientists have found, people and other animals will often change their original preferences when presented with a third choice. Not so with ants. These insects also shop for homes but not quite in the way that humans do. Solitary worker ants spread out, looking for two main features: a small entrance and a dark inside. If an ant finds an outstanding hole---such as the inside of an acorn or a rock crevice---it brings another worker ant to check it out. As more ants like the site, the number of workers in the new hole grows. Once the crowd reaches a critical mass, the ants race back to the old nest and start carrying the queen and larvae to move the entire colony. To test ant rationality, Stephen Pratt, a behavioral ecologist at Arizona State University in Tempe, and a colleague designed a series of possible nests for 26 ant colonies. The duo cut rectangular holes in balsa wood and covered them with glass microscope slides. The researchers then drilled holes of various sizes into the glass slides and slipped plastic light filters under the glass to vary the features ants care about most. At first, the colonies only had two options, A and B. A was dark but had a large opening, whereas B was bright with a small opening. As with humans, the ants preferred both options equally: The researchers found no difference between the number of colonies that picked A versus B. Then the scientists added a third option, called a decoy , that was similar to either A or B in one characteristic but clearly worse than both in the other (a very bright nest with a small opening, for example). Unlike humans, the ants were not tricked by the decoy, the team reports online today in the Proceedings of the Royal Society B. Although a few colonies picked the third nest, the other colonies did not start favoring A or B and still split evenly between the two. Pratt speculates that ant colonies avoid making the irrational decision because, unlike humans, each ant doesn't evaluate all options before making a choice. When the scouts find a nest, they're unaware of what else is out there, and either they pick the nest or they don't. "The group may do better precisely because the individuals are ignorant," Pratt says. Melissa Bateson, an ethnologist at Newcastle University in the United Kingdom, believes the findings could have "really interesting implications for the benefits of collective decision-making, which we could learn something from." Many grant-review boards, for example, behave like ants: Reviewers see only a subset of the total grant applications and thus have to make a decision without seeing every option. According to Stephen Pratt, why are the ant colonies able to make the rational choice in comparison with humans? | [

mmlu_train_61237 | Jamie Oliver, a lively Britain guy, loves to share his secrets. In his first television show,The Naked Chef, Oliver taught everyone to make simple but delicious food. In Jamie's Kitchen, he taught young people how to prepare meals. His next show,Jamie's School Dinners, is about changing the food that students eat. Oliver saw that some schools in Britain were serving junk food--food that is easy to eat but unhealthy. Although it can be delicious, junk food is not very good for children. It is sometimes bad for their health, because it doesn't give them the energy they need at school. They sometimes can't think well or feel down, and they sometimes put on weight. Some of the junk food that Oliver wants to change is canned spaghetti, chicken nuggets, French fries, soda, and muffins. He encourages schools to serve fresh and health meats, vegetables and fruits. He helps the school cooks to make healthy dinners without junk food. People liked Oliver's idea of bringing quality food to schools. Thousands enjoyed his television show. But Oliver wanted them to do more than just watch. At hisFeed Me Betterwebsites, he collected over 270,000 signatures from people. Oliver sent these signatures to British Prime Minister Tony Blair. Then Blair promised to help change the school kitchens, teach school cooks to make healthy food, and spend more on school dinners.

mmlu_train_58312 | A private sixth grade is set to start its lessons at 1.30 pm every day because the school's teacher thinks his students will study better after a morning lie-in . Instead of rising early for a 9 am start, students at the PS15,000-a-year Hampton Court House, in East Molesey, Surrey, will get to enjoy a lie-in and work from 1.30 pm until 7pm. Head teacher Guy Holloway says the move for all sixth grade students, set to begin from September, has been made according to research by scientists. He predicts that not only will his students aged 16 and upwards get great night's sleep, but their productivity will also be improved. The co-educational school will have the latest start time in the UK, and will be the only one to begin lessons in the afternoon. Experts say young people are programmed to get up later, and that rather than laziness it is simply a shift in their body clocks. 'There are 168 hours in a week and how productive they are depends on how they choose to use those hours,' said Mr Holloway. 'At Hampton Court House we don't think we have the answer for everybody; it's about what works in our school. We want to get them into a condition where they can get great sleep and study well.' He said students would also benefit from reduced journey times as they travel to and from school after rush hour . Year 10 student Gabriel Purcell-Davis will be one of the first of 30 A-level students to start at the later time. 'I want to wake up in my bed, not in my maths lesson,' said the 15-year-old.

mmlu_train_23415 | People born in winter are more likely to suffer mental health disorders, according to a recent study carried out by researchers at Vanderbilt University in Tennessee. Researchers raised baby mice from birth to weaning in either "summer" light cycles of 16 hours of light and 8 hours of dark or "winter" cycles of 8 hours of light and 16 hours of dark. A third group experienced 12 hours of light and 12 hours of dark a day. Then half the winter mice stayed in a winter cycle, while half switched to a summer schedule. The summer mice were similarly _ . The mice raised in equal periods of light and dark were split into three groups, one of which stayed on the 12hour schedule, one of which joined the winter group, and one of which joined the summer group. After 28 days, it turns out the summerborn mice behaved the same whether they stayed on the summer cycle or switched to winter. But among the winterborn mice, those stayed in winter kept their previous schedule, while those that switched to summer stayed active for an extra hour and a half, which indicates that mice born and weaned in a winter light cycle showed dramatic disruptions in their biological clocks. The finding is the first of its kind in mammals, and it could explain why people born in winter are at higher risk for mental health disorders including bipolar depression, schizophrenia and seasonal affective disorder. "We know that the biological clock regulates mood in humans,"said study researcher McMahon. "If the mechanism similar to the one that we found in mice operates in humans, then it could not only have an effect on a number of behavioral disorders, but also have a more general effect on personality."

mmlu_train_29274 | They say that sticks and stones may break your bones, but words will never hurt you. Yet childhood bullying really can damage your long-term health. Gone are the days when bullying was considered an unavoidable and finally harmless part of growing up -- just last month we learned that childhood bullying can lead to poorer mental health even into middle age. Now William Copeland at Duke University in Durham, North Carolina, and his colleagues have shown that it can have lasting physiological effects too. They tracked 1,420 nine-year-olds right through their teens. Each child was seen up to nine times during the study and asked about bullying. The team then measured levels of C-reactive protein (CRP) in their blood. CRP is a marker of inflammation linked to higher risk of cardiovascular disease and problems like diabetes. "Because we were collecting biological samples throughout, we were able to look at CRP levels in subjects _ their bullying involvement." says Copeland. "This really gives us an idea of the changes bullying brings about." Although CRP levels naturally rise in everyone during adolescence, levels were highest in children who reported suffering from bullies. Even at the ages of 19 and 21, children who had once been bullied had CRP levels about 1.4 times higher than peers who were neither wrongdoers nor victims. In a cruel twist, the bullies had the lowest levels of all, suggesting they didn't suffer the same health risks. They may even see a benefit from their behavior, though Copeland stresses it doesn't defend their actions. "The goal would instead be to find other ways to produce this protective effect without it being at someone else's expense." he says. Andrea Danese at King's College London has before shown that ill-treatment during childhood can lead to high levels of inflammation in adult life. "This new study is a helpful addition in showing that these effects extend to another important childhood stressor." he says. He suggests that care workers monitor levels of CRP in children having psychotherapy to see if it is helping to reduce the stress of being bullied. What does the phrase "prior to" in Para.2 mean? | [

mmlu_train_56880 | People who have a fear of ugly insects will want to stay far away from Lake Tawakoni State Park in north Texas, US. A giant spider web was recently found there. The thick web is swarming with millions of little spiders. Stretching across several acres it blankets a number of trees, bushes and even the ground. While the web may make some people nervous, it has become a big attraction for others-especially for unlucky insects. "At first, it was so white that it looked like fairyland," said Donna Garde, the park's manager. "Now it's filled with so many mosquitoes that it's turned a little brown." Most spiders work alone, which is why the discovery of the huge web has caused such a stir. Scientists across the country have been debating its origin. Some spider experts' say the monstrous web may have been weaved by social spiders. Social spiders work together to build larger webs to catch small insects. However, those webs take years to build. Park officials say this web was formed in just a few months. Others say it could be the work of millions of tiny ballooning spiders. These types of spiders 'fly' by throwing out thin threads of silk, which they use to ride air currents . In 2002, a similar giant web made by ballooning spiders was discovered in a field in Canada. Texas entomologist Herbert Pase says the giant web is very unusual. "From what I'm hearing, it could be a once-in-a-life-time event," he said. But John Jackman, an entomologist and professor at Texas A&M University, disagrees. Jackman says he hears reports of similar webs, like the one in Canada, every few years. "There are a lot of folks that don't realize spiders do that," he said. "Until we get some samples sent to us, we won't know what species of spider we're talking about." Park officials expect the web to last until fall when the weather gets cooler. That's when the spiders begin dying off in the park. What is the main reason for scientists' excitement and argument about the giant web? | [

mmlu_train_61805 | Roll over, sit and fetch aren't commands normally given to a robot, but the smart toy company WowWee has developed a new way of owning a puppy. CHIP (Canine Home Intelligent Pet) is a robotic dog with blue LED eyes and pointy ears and can sit, shake, dance and make all types of dog noises. It also has tracking capabilities to help locate its owner. "The beauty about CHIP is that it has its own thing going on," said Sufer, CTO at WowWee. "It has its own life and own kind of intelligence. Even if you're not around, it's always doing something." CHIP uses wheels to get around and is loaded with sensors that give it a 360-degree view to find its ball. The pup is Bluetooth enabled, which connects to a wristband worn by its owner. The wristband, similar to a watch, displays icons for different commands such as a thumb-up, which allows you to give your pup a digital belly rub. With its owner wearing a smart wristband, it can even follow him around the room. "We worked on CHIP for about five to six months," Davin Sufer, told dailymail.com, "We typically come up with a concept, model and product and get it on shelves within a year." The company plans to start shipping units by next fall, which will allow them to load up the robotic dog with sensors and add many more animated responses per-owner interactivity. The high-tech toy company made its debut in 2004 by releasing the 1.5 foot RoboSapien, which sold millions of units. MiP, which hit shelves last year, is a seven inch tall robot covered in white with black accents. Users can direct it, change its emotions and make it dance to any song on your iPad. It's loud, fast and active. About 15 years ago, a company called ToyQuest developed the first ever electronic robotic dog---Tekno, the Robotic Puppy. The company sold over seven million units in the first season and 40 million more during its original four years of production. Tekno was built with over 160 emotions and instructions, but most importantly offered consumers a quick look into the future. From the passage, we can know _ . | [

mmlu_train_26296 | At the recent O&P Extremity Games, I had the opportunity to observe a new generation of athletes with disabilities who were skateboarding and rock climbing. These young people really showed the promise of how rewarding physical activities are! We disabled can - and should be -- as active as anyone else. When we get and stay active, we will feel better, be able to do more, have healthier bodies, and look better. It is a fact that exercise actually produces energy and builds on itself. The more we exercise, the fitter our bodies are, and thus the more energy we have to enjoy recreation and the pleasure of life. Not everyone is cut out to be a competitive athlete, but there are things that we can do to strengthen our physical well-being. Experts recommend that spending as little as 30 minutes each day on physical activities provides benefits including lower risk of heart disease, cancer, high blood pressure, diabetes and other serious diseases. Taking steps to become physically fit does not have to mean acquiring expensive training equipment or a gym membership. Exercise can include simple walking and running, gardening, cleaning the house, swimming, tennis, bicycling (stationary or on the road) and so on. The key is to do it on a regular basis. Healthy lifestyles also require good nutritional habits. When choosing foods, nutritionists advise whole grains, flesh fruits and vegetables, fish, and lean cuts of poultry and meat. The benefits of drinking eight full glasses of water a day are also _ . Water provides the means for nutrients to travel to all our organs, improves skin tone , regulates body temperature and contributes to muscle strength and control, which is confirmed by scientists. Fitness results in completing the tasks of daily living, working a full day, and still having energy to participate in recreational activities. By being fit, you'll find that you enjoy recreational activities even more because you won't be tired or suffer from gore muscles. It is time, folks, to get moving. So let's all get out there and do some exercise! What do we learn from the passage? | [
"Water can provide nutrients for us to improve skin tone.",
"Extreme sports have little to do with normal people.",
"One can enjoy recreation and the pleasure of life by doing extreme games.",

Each year, people spend billions of dollars on their four-legged pals, making sure the lovable dogs have enough food to eat and lots of toys to play with. Dogs love people, too. They lick their faces, protect their homes. Where did these four-legged companions come from? Some scientists believe that they have found the answer. Scientists have long known that dogs evolved from wolves. Exactly when the transformation from wolf to dog actually took place, however, remains a mystery. Some said dogs evolved as a separate species 135,000 years ago in two parts of the world. One group of dogs developed in Europe and Asia from Asian wolves. The other group evolved in North, Central, and South America from American wolves. Now researchers say those theories are wrong. New studies suggest that _ dogs first appeared 15,000 years ago in eastern Asia. Scientists also say that every modern dog descended from approximately five female Asian wolves, the mother of all modern dogs. Scientists suspect dogs first set paws in North America by following settlers across a land bridge that once linked northern Asia and North America.

mmlu_train_44776 | Long-time exposure to air pollution can lead to physical changes in the brain and cause trouble in learning and memory, and even anxiety. This is suggested by the results of new research on mice. While other studies have shown the harmful effects of polluted air in the lungs and heart, this is the first to show the negative effect on the brain. The team of Laura Fonken, Randy Nelson , from the Ohio State University, the USA, has spread to the brain a previous line of research which found that fine particulate matter floating in the air mainly because of air pollution caused by humans, causes swelling in much of the body, and may be related to high blood pressure problems, and some other diseases. In the research Fonken and his colleagues exposed mice to polluted air for six hours each day, five days a week, over a period of 10 months, almost half the average life length of mice. Polluted air contains fine particles created by cars, factories and natural dust. Fine particles of this kind are tiny, about 2.5 micrometers in diameter , or about one-thirtieth the width of a human hair. These particles can go deep into lungs and other organs. The concentration of this particulate material to which they exposed mice is equal to the concentration at which people can be exposed in some polluted urban areas. After a period of 10 months, the researchers got the animals to have a series of behavioral tests. Both the behavior of mice and the results of neurological tests done to them show that those within the polluted air had more problems in learning and memory, and higher levels of anxiety. The results suggest that long-time exposure to polluted air can have measurable negative effects on the human brain and can cause a variety of mental health problems. This could have important consequences for those living and working in polluted urban areas. What harmful effect of polluted air is mentioned in other studies? | [

mmlu_train_9373 | When English as a foreign language is taught to children at the primary and early secondary levels of education, it is generally taught with a general education aim in mind--that is, it is regarded as a "good thing" for them to learn a foreign language as a part of a broad education. There is usually, however, no immediate and specific requirement for such children to make use of the language in any communicative situation. The purpose of learning the language is essentially a "deferred" purpose, deferred till the tertiary level of education, normally at university, where, it is agreed, a knowledge of English would be helpful in their academic studies. Immediate aims of learning English are defined by the requirements of examinations. Inevitably what is taught to primary and secondary level children is not a communicative knowledge of English language use, but a knowledge of how the rules of English operate. The language system is taught by means of systematic audio-lingual drill and exercise techniques based on habit formation theory of learning and a structural description of English. This may be an effective manner of teaching English usage, but it is less certain that an understanding of how these rules are related to language in use for communicative purpose is an automatic result of this instruction. What the thousands of children succeed in learning in this way is what is necessary in order to pass examinations. Whether such examinations accurately reflect the uses to which English will be put at the tertiary level is another matter altogether. Adults, on the other hand, unless they are learning a foreign language for "pleasure" at evening institutes, as a "cultural" and social experience, are generally highly conscious of the use to which they intend to put it. That use is frequently associated with an academic or professional requirement; without a knowledge of the foreign language, their development in their chosen sphere of work could be restricted or at least adversely affected. Which of the following statements is TRUE according to the passage? | [

Things were similar last year in the Sichuan earthquake. Thousands of people were buried in the ruins and lost their lives. What if we could have warned them? People are always _ to find a way of preventing buildings' collapse. Better materials and technology help,but they are not a solution. Just like humans,a building has its own life cycle from "birth" to "death".If we know when a building is going to collapse,we can repair it in advance or get out of it before it falls. Now,scientists at the University of Illinois have developed a material that turns red before it breaks. The invention could be used in things like climbing ropes or bridge supports. The research was led by Nancy Sottos,a professor at the university's Beckman Institute,and Douglas Davis,a graduate research assistant. The secret behind the colorchanging material is a type of molecule .A molecule is a group of atoms held together by chemical bonds. Imagine you and your friends standing in a circle,holding hands. Each person stands for one atom,your hands represent the bonds,and the entire circle represents a molecule. If one person lets go of his or her hands,the molecule changes color. The research team put the molecule into a soft material. When the researchers stretched the material,it turned bright red for a few seconds before it broke into two pieces. When they repeatedly stretched and relaxed the material,without breaking it,it only turned a little red. The major problem is that light can get rid of the red color. When the team shone bright light on the molecule,the broken bond was fixed,and the color disappeared. If the bright light keeps the red color from appearing,the material's warning system will be useless. Scientists still have a lot of work to do before the colorchanging molecules can be used outside the lab. What can we infer from the passage? | [
"The colorchanging molecules are certain to be used outside the lab.",
"There will be no collapse with the help of the colorchanging material.",

Others charge for courses and provide credits. The idea is still developing. So far, most massive open online courses are in computer science, technology, mechanics and engineering. For example, students around the world are taking a free course called "Building a Computer Search Engine." Two computer scientists, Sebastian Thrun and David Evans, are offering this course throughudacity.com. There are no education requirements for the course. The students watch short videos. Then, says Mr. Evans, they take informal quizzes after the videos each week for six weeks. DAVID EVANS: "Quizzes are part of the lecture to keep students engaged and keep them thinking, for students to be able to check that they understood what we covered. Those are not graded and students try those as often as they wish. They can repeatedly watch the videos and take the quizzes whenever they want." Students receive homework. They join online groups to exchange questions and answers about the course. The teachers hold office hours to answer questions that the students have voted to send them. They also present their own questions and observations to the students in order to help them make a deeper impression of the course. The students take a final examination to show where they rate in the class Everyone who finishes the course receives a grade and proof of completion. Top students get letters documenting their work.

mmlu_train_62198 | What looks like a black hole, behaves like a black hole, but is bigger than a black hole? Two black holes! Astronomers last week discovered a pair of enormous black holes far out in the galaxy that appear to be dancing toward each other. However, astronomers say the collision is not likely to occur for several million years. Black holes are objects in outer space that are so dense that nothing can escape their gravity. They often sit in the center of a galaxy -- like the Milky Way --and suck up everything near them. The gravitational pull of a black hole is so intense that not even light (Which travels faster than anything else in space) can make it past without being swallowed. Black holes, like the one at the center of the Milky Way, are enormous. Scientists call some of them "supermassive", because they can be a few million times the size of most stars. Their size, their mass, and their inescapable gravity make black holes a giant force of nature in outer space. Because there is no light near black holes, astronomers cannot actually see them; they are completely invisible to us on the Earth. Scientists manage to detect the existence of a black hole by watching what happens to other objects, or matter floating in space. So how did scientists manage to get a good look at a region so faraway? The team used an orbiting NASA observatory known as Chandra. This special observatory uses X-rays rather than light to watch far out into space. Right before a star gets sucked into a black hole, it produces a large number of X-rays.

mmlu_train_5451 | An Australian company, Smart Car Technologies, has developed a system that lets drivers know when they're speeding. When the technology becomes commercially available, it could help lead-footed drivers avoid tickets and also save lives. The company that developed the product hopes to convince Australian government agencies to put the technology into use in their automobile fleets. The product, called Speed Alert, links real-time location data and speed obtained with the help of GPS to a database of posted speed limits stored in a driver's PDA or programmable mobile phone. The setup of the product does not need to be hooked up to a car's speedometer. In fact, it is entirely portable. It will also work with newer phones and PDAs that have built-in GPS receivers. If a driver exceeds the speed limit, the speed is shown and an alert sounds. Michael Paine, an Australian vehicle design engineer and traffic safety consultant, was hired to analyze the product. He told Live Science that his colleagues in the road safety field are "very enthusiastic" about what they're now calling "intelligent speed alert." Other research, according to Paine, shows that 40 percent of all traffic deaths involve speeding. There is also a potentially controversial future use: "Since the system is so portable, it would be easy to make it a requirement for teenage drivers to always use a speed alert device when driving," Paine said. "The system even has the capability to record speeding violations, so parents can monitor their teenage drivers." The product will soon go on sale in Sydney.

In order to be able to develop the equivalent of a periodic table of the elements, Thomson had to be able to classify knots -- find out which different knots were possible. This sparked a great interest in the mathematical theory of knots. A mathematical knot looks very much like a familiar knot in a string, only with the string's ends joined. In Thomson's theory, knots could, in principle at least, model atoms of increasing complexity, such as the hydrogen, carbon, and oxygen atoms, respectively. For knots to be truly useful in a mathematical theory, however, mathematicians searched for some precise way of proving that what appeared to be different knots were really different -- the couldn't be transformed one into the other by some simple manipulation . Towards the end of the nineteenth century, the Scottish mathematician Peter Guthrie Tait and the University of Nebraska professor Charles Newton Little published complete tables of knots with up to ten crossings. Unfortunately, by the time that this heroic effort was completed, Kelvin's theory had already been totally discarded as a model for atomic structure. Nevertheless, even without any other application in sight, the mathematical interest in knot theory continued at _ point for its own sake. In fact, mathematical became even more fascinated by knots. The only difference was that, as the British mathematician Sir Michael Atiyah has put it, "the study of knots became a special branch of pure mathematics. " Two major breakthroughs in knot theory occurred in 1928 and in 1984. In 1928, the American mathematician James Waddell Alexander discovered an algebraic expression that uses the arrangement of crossings to label the knot. For example, t2-t+1 or t2-3t+1, or else. Decades of work in the theory of knots finally produced the second breakthrough in 1984. The New Zealander-American mathematician Vaughan Jones noticed an unexpected relation between knots and another abstract branch of mathematics, which led to the discovery of a more sensitive invariant known as the Jones polynomial.

Many people aren't conditioned to the physical stress of outdoor activities and don't know the dangers of being outdoors in cold weather. Those who like winter sports can suffer accidental hypothermia if they don't make certain preparations. Hypothermia means the body temperature has fallen below normal. It occurs when your body can't produce enough energy to keep the internal body temperature warm enough. It can kill you. Heart failure causes most deaths in hypothermia. Children, the elderly and those with heart disease are at special risk. As people age, their ability to keep a normal internal body temperature often decreases. Elderly people can suffer hypothermia without knowing they're in danger because they can't notice the cold conditions as quickly as the young. Besides cold temperatures, high winds, snow and rain can also steal body heat. Wind is especially dangerous because it removes the layer of heated air from around your body. At 30 degrees Fahrenheit in a 20-mile-per-hour wind, the cooling effect is equal to calm air at four degrees. Similarly dampness causes the body to lose heat faster than it would at the same temperature in drier conditions. To keep warm, wear more clothes. This traps air between layers. Also, wear a hat or head scarf. Much of your body's heat can be lost through your head. Keep your hands and feet warm, too, as they tend to lose heat rapidly. Don't drink alcohol before going outdoors or when outside. Alcohol makes you feel warm at first because blood vessels in the skin expand. But heat is then drawn away from the body's important organs.

mmlu_train_60132 | American colleges and universities consider a number of things about a student who wants to be admitted. Experts say the most important thing is the students' high school record. Besides, student's interests and activities may also play a part in getting accepted. But in most cases another consideration is how well the student did on college entrance exams. Here we'd like to discuss two of these tests: the SAT and the ACT. Most American schools accept either one. The SAT measures reasoning skills in mathematics and language. Students have almost four hours to complete the SAT. The newest part is an essay. Students have twenty-five minutes to write an answer to a question. The SAT costs 41.5$. Besides, the international processing charge is 22$ more. And test-takers in India and Pakistan must also pay a 21.5 $ security charge. Students may also need to take SAT subject tests in areas like history, science and foreign language. Subject tests cost eighteen dollars each. The ACT is an achievement test. It is designed to measure what a student has learned in school. Students are tested in mathematics, English, reading and science. A writing test is offered but not required. Without it, the ACT takes about three hours to complete. The essay part adds thirty minutes. The ACT costs forty-nine dollars to take outside the United States. The writing test costs an additional fourteen dollars. Which of the statement is true according to the text? | [

mmlu_train_51216 | Researchers recently found that hackers took control of 300,000 home routers . Once your home router has been controlled, hackers could redirect your network to malicious websites controlled by hi-tech thieves who could then steal your online back details and other sensitive data. However, there are some simple steps you can take to protect your router. Say no to 12345 passwords First, never leave your router open without a password and make sure you change both your Wi-Fi and router login password from the default one it comes with. If you use the default password , this could give someone access to the router setup, which could allow them to change your router settings, including viewing any security keys. Don't broadcast it Make sure you don't show up in other people's wireless network scans. Know your network name so you can easily enter it into any devices you want to access that network. Other people do not need to know your network name. To prevent outsiders from seeing your network's name and attempting to join your wireless network, turn off broadcasting in your router's settings. Invite only please One way you can ensure no one else joins your network without your permission is to enable your router to only allow certain devices to connect, and ban all others. To do that you can filter by media access control (MAC) addresses. Turn it off This is a simple piece of advice that can go a very long way in keeping you safe. Simply turn off your router when you're not using your network. If you're at work all day and no one's home, why keep it running? Build a firewall The firewall built into your router prevents hackers on the internet from getting access to your PC so it's always worth enabling it to help add an extra layer of security. However, it does nothing to stop people in range of your Wi-Fi signal from getting onto your network - and as said, a router in the wrong place means your Wi-Fi signal could reach pretty far. For further protection, you should run software firewalls on the individual PCs on your networks. The purpose of the passage is to tell _ . | [

mmlu_train_37656 | Skipping classes, particularly big lectures where an absence is likely to go undetected, is a tradition among college undergraduates. These days, however, some professors say they're seeing more _ , as students make the most of new technologies as learning aids. Americ Azevedo taught an "Introduction to Computers" at the University of California, Berkeley, US last semester. By visiting the course's website, the 200 enrolled students could download audio recordings or watch digital videos of the lectures, as well as read the instructor's detailed lecture notes. But there was one big problem: So many of the undergraduates relied on the technology that at times only 20 or so actually showed up for class. Doug Suda, 19, a student in Azevedo's class last semester, said he skipped about three-quarter of the lectures. It's largely because he was busy with an off-campus job and was taking the course to fulfill a business major requirement. At the end of the term, Suda prepared hurriedly for the final exam by watching videos of about 15 lectures over three days. "If I hadn't that... I would probably fail the class," said Suda, who instead received a B-plus. Despite the concerns about absenteeism, schools are increasingly experimenting with ways to let students watch or listen to lectures on their computers or digital music players, like iPods. Last month, Harvard Medical School began "Podcasting" lectures. Students can download them into digital musical players, and study while they, say, go for a walk. As many academics accept the electronic innovation, others are pushing back. To encourage attendance, they are applying low-tech tactics, like giving more surprising quizzes or cutting back their online offerings. Lee Chanian, a UCLA economics professor, says "too much technology leads to passive learning environment and encourage more absenteeism". He now puts fewer lecture materials online, and provides extensive notes only for the most complicated topics.

mmlu_train_28934 | There are new findings that not enough sleep may cause people to gain weight. Researchers say a lack of sleep can produce hormonal changes that increase feelings of hunger. In one study, researchers in the United States examined information on more than 1000 people. The people had taken part in a long-term study of sleep disorders. Some people slept less than five hours a night. They had 15 percent higher blood levels of a hormone called ghrelin than people who slept eight hours. And they had 15 percent less of the hormone leptin. Experts say ghrelin helps make people feel hungry; leptin makes you feel full. The scientists say these hormonal changes may be a cause of obesity in Western societies. They note the combination that sleep limitation is common and food is widely available. The results were not affected by how much people exercised. People who are awake longer have more time to burn energy. But the researchers say loss of sleep may increase hunger especially for high-calorie foods, so people gain weight. It seems that, for survival, the body may be designed to store more fat during times with less sleep. Researchers from Stanford University in California and the University of Wisconsin did the study. They found that the best amount of sleep for weight control is 7.7 hours a night.The Public Library of Science published the findings in its journal Medicine .

The arrival of the American university on China mainland is an example of what is being called the "globalization" of education and it is hoped that this trend will influence the quality of education in all of China's universities by raising the standard of teaching. NYU Shanghai's class of 2017(students will graduate in 2017) is made up of 295 students from China, America and other countries. The students will study liberal arts courses for two years before choosing a major and when they graduate, they will receive a degree from NYU and a degree from ECNU. All the classes will be taught in English, using the teaching methods in American universities. Students will be pushed to take risks in the classroom, pushed to speak up and pushed to say things that are not completely correct, which can make them understand that it's OK for them to make mistakes in class. This style of learning will be challenging for many Chinese students, because they will be mixed with the foreign students both in the classroom and in the dormitory. Living and studying with foreigners day to day will provide Chinese students with a cultural as well as academic education and it's hoped that this cross-cultural experience will benefit them when they seek jobs in the competitive global market. China's interest in partnering with foreign universities comes at a time when western universities are trying to expand. They realize that information, technology and business are now borderless; they also realize education should be borderless too.

It is a hairy orange-brown creature with a sweet face and big eyes The animal has small. rounded ears and lives in the trees An adult weighs one kilogram and measures about 75 centimeters. with half of those centimeters taken up by its ringed tail Most of the time. it likes to eat fruit, although it also eats meat. Active at night, the animal has lived in Colombia and Ecuador for a long time. But the olinguito did not exist in science books before now. Kristofer Helgen, director at the National Museum in Washington, led the research team that confirmed the existence of the olinguito. It had been mistaken more than a century ago for a look-alike animal -- a similar but larger olingo . Mr. Helgen had been studying olingos in a museum for ten years. At that time. he observed a difference in the size and shape of the heads and teeth. That led him on an effort to prove he was looking at an animal never before described by science. He got lucky when he communicated with a zoologist in Ecuador. The animal expert there made a short video that shows an olinguito in the trees. The video confirms that the oiinguito is different from the olingo Mr. Helgen says tens of thousands of olinguitos live in the wild and are not in danger of disappearing forever.

Some employed the most advanced technology ever. Some of the TVs used a new technology called Organic Light Emitting Diodes, or OLED. They were thinner, lighter, offered better color1 and were brighter than traditional LEDs. Smart TVs this year were smarter. Many offered technology that let users have a more personalized experience. One such TV from the electronics company TCL uses sensors and voice recognition to determine who is watching. It then offers programming based on the specific user. Another TV from Panasonic offers a similar personalized user experience. In addition to television technology, size also played a major part in CES 2013. Televisions varied in size from big to bigger, with at least two companies -- Samsung and HiSense -- exhibiting TVs measuring 110 inches. The yearly Consumer Electronics Show is the biggest technology trade show in North America and one of the biggest in the world. Gary Shapiro is president and CEO of the Consumer Electronics Association, the group that organizes CES. He gave one of the keynote speeches on opening day. "Now you know that CES is more than a trade show. It's a gathering of the brightest minds and the top leaders from many industries and those seeking a glimpse into the future." That glimpse into the future included a look at digital health and fitness devices, which were also big at CES 2013. There were devices that track your activity and others that measure blood pressure, heart rate and weight. There was even a fork that tells you when you are eating too fast.

Many kinds of agriculture depend on these small, social insects. Without bees, fruit and nut growers as well as many other farmers would not have a crop. There are more than 20,000 kinds of bees. But only honey bees make enough honey for people to use. Honeybees are highly-organized social insects. They work together in a group, called a colony . Each colony lives in a hive . It contains one queen bee -- she lays all the eggs from which the members of the colony come. Each colony has only a few hundred males, called drones. The majority of all bees in a colony are workers, which are all females. Bees even have a special stomach, called a honey stomach, which is used to store sweet fluid that the bees gather from flowers. Bees also have long hairs on their body and legs. These hairs capture pollen as bees go from flower to flower. Some of the pollen is taken back to the hive. Some, however, is passed to the next flower. This is how many plants are fertilized. Pollen is the reproductive material of plants. Many important agricultural crops depend on bees for fertilization. Inside their hives, bees store sweet liquid from flowers and pollen as well. They may even gather sweet liquid from some other kinds of insects. These kinds of sweet liquid are also stored in the hive. Bees make honey through a process. They add liquid from their own mouths to sweet liquid into simple sugar. As the honey is stored, it dries. It becomes thicker and darker. Although bees are often thought of as honey makers, they provide a surprising number of products. Also, their greatest economic value is in fertilizing crops-not in making honey.

At that point, there will be so much music to choose from and you'll be able to sample things before you buy them. But the question will be how I find what I'm looking for and how I do find the music that might interest me.

Autism is more common in boys than girls. What causes it is not clear. Scientists are studying genes and possible environmental influences. Doctors usually cannot confirm a diagnosis of autism until a child is about three years old. Rebecca Landa is a researcher at the Kennedy Krieger Institute and Johns Hopkins University School of Medicine in Maryland. Professor Landa wanted to find out what differences in development might be seen earlier. She led a new study that observed 235 babies between six and 36 months of age. "At six months of age, the signs of some risk for developing communication and social delays, including autism, include motor delays. Like when you lay your baby on their back and you pull them by the arms gently into a seated position, the baby's head may nod back behind the shoulders, like poor head control. So that does not mean that the baby is going to have autism, but it does mean the baby needs to have some exercises to strengthen their body. And when they strengthen their body, they are better able to play with toys and engage with people, which then goes on to help them have better outcomes." By the time a baby is one year old, signs of possible autism include difficulty in using words and not looking eye-to-eye or reaching out to other people. By 14 months, the baby might smile less and use language less. However, Professor Landa says these signs can be so small that they might be missed during a short health exam. "It's important for parents to stay tuned into their children's development, and if a parent is concerned about a child's development, for professionals to listen to them." The earlier parents notice delays, she says, the sooner they can begin doing simple things that may help improve their child's development. For example: talking to the child about what they are doing, commenting when the child shows them something, and playing simple games that keep the child's attention.

A medical team completed the 11- hour operation Friday night and said 8-week-old Rebecca Martinez died seven hours later. Doctors had warned after the surgery that the girl would be at great risk of death. " We knew this was a very risky surgery , and now we accept what God has decided , " Rebecca's father , 29-year-old Frankin Martinez, said at a news conference with his wife. " Rebecca is no longer with us physically , but no one will forget her." Martinez said the family would bury Rebecca in a private funeral later in the day. The girl lost a lot of blood in the operation, which apparently ( ) caused her to suffer a heart attack , said Dr. Jorge Lazareff , the lead surgeon . Friends and family donated almost 4 gallons of blood for surgeons to use Rebeca's operation "This was not a failure or an error ," Lazareff said . " When we left here last night the girl was in stable condition. At some point in the middle of the night , she started to bleed." Rebecca was born Dec. 10 with the undeveloped head of her twin, an exteremely rare condition known as craniopagus parasticus . Rebecca was the eighth documented case in the world of craniopagus parasiticus, doctors said. All the other infants documented to have had the condition died before birth , making Rebecca\s surgery the first known operation of its kind. Without an operation , Rebecca would have barely been able to lift her head at 3 months old. Her doctors said the pressure from the second head would have prevented her brain from developing.

Of course everyone knows that exercise is good for the body.However, studies have shown that when exercise is performed in groups, it's not only great for improving physical health but for psychological health. It's an opportunity to be social, release endorphins , and improve your strength. Additionally, group exercise creates a community feel and the shared common goal motivates participants to work hard. The instrumental support of taking on a fitness journey with others proves more effective than going to the gym alone. Another beneficial aspect of group exercise is the informational support participants receive from the instructor.Many people fear the gym because they feel lost and don't want to embarrass themselves. If you feel you can relate, then group training is an even better option for you. It's a great opportunity to learn more about fitness through the clear instruction and supervision of a fitness instructor. If you're tired of wandering around the gym wasting time and becoming bored, !you can attend an upbeat group fitness class that'll keep your workout on track. Don't let fitness frighten you! If you're serious about wanting to live a healthy lifestyle, it's extremely important to surround yourself with people who'll provide you with the proper emotional support. I wouldn't scold anyone for deciding to party on weekends and in turn I wouldn't expect anyone to give offence to me for focusing on my health. Surround yourself with people who uplift, encourage and understand you! Make fitness even more fun by trying something new or any group fitness class, with a friend. Plan to go for a jog together. Then try a fun healthy restaurant or fresh juice bar! Fitness can be both fun and social! Surrounding yourself with people who'll provide you with respect support can be very beneficial while working towards reaching health and fitness goals.

Among those in the study who developed lung cancer, the researchers saw a small increased risk related with vitamin E supplements in addition to the expected connections to smoking,family history and age. This added up to a 28 percent increased risk of developing lung cancer for those taking 400 mg of vitamin E supplements daily for 10 years,the researchers said. "For people--especially smokers--I suggest that they not take vitamin E(as a supplement) unless they have a very strong reason to take it." Slatore said. The idea that vitamin supplements are healthful,or at least not harmful.comes from the desire of many people to match the benefits of a healthful diet with a convenient pill,Tim Byers of the University of Colorado School of Medicine.wrote in an essay. According to the study of researchers,_may increase the risk of lung cancer. | [

mmlu_train_25255 | On the night of July 6, 1943, a plane took off from an Air Force base in England to stop German fighters over the English Channel. Piloting the plane was Captain Thomas Nash. Looking westward, Nash saw twelve orange lights in a row, moving at a very high rate of speed. Thinking they might be a new German weapon, he swung the plane around and headed directly for the lights, but they disappeared. Captain Nash may have been the first to see such orange lights but he wasn't the last. His experience was repeated many times by pilots during World War II both in England and Far East. What were they? No one knows for sure, but there is an interesting theory to explain them. According to this theory, the orange lights are space animals---animals specially adapted to life in the upper atmosphere just as some living things are adapted to life at the bottom of the sea. These space animals, the theory says, live so far up in the atmosphere that they are not in sight from the earth. They feed partly on the air and partly on energy from the sunlight. Being almost pure energy themselves, their body shine at night. During the day, however, they are invisible. Before World War II, continues the theory, there was little radiated energy on the earth's surface. Then came the development of rockets, nuclear power stations and something like that. The space animals are attracted to these kinds of energy of food. At night when there is no energy from the sunlight, they come down into the lower levels in search of a meal. They may even float into the range of human eyesight. This explains the fact that they have been sighted many times from the earth since 1943. If the space animal theory is correct, the orange lights come down to the lower levels in order to _ . | [

mmlu_train_33305 | JIUQUAN, Gansu Province, Sept. 6(Xinhua) ---- China's manned spacecraft Shenzhou-7 will be launched at an appropriate time between Sept. 25 and 30 from the Jiuquan Satellite Launch Center in northwestern Gansu Province, a spokesman said here on Saturday. The mission will accomplish the first spacewalk by Chinese astronauts. "All the major systems involved in the launching are now in the final preparation. The main tests for the spacecraft, the Long-March II-F rocket, suits for the space walk and a satellite accompanying the fly have also been finished, " said the spokesman. In addition, the ground control system is fully prepared, including the launch site, the landing site, and the communication for observation and control. When Shenzhou-7 enters its orbit, one of the three taikonauts will conduct a space walk, said Zhao Changxi, a senior scientist with the project, earlier. According to Zhao, cameras would be fixed outside and inside of the ship for live broadcasting of the space walk. While the last mission of Shenzhou-6, with a crew of two, was aimed at several days of manned flight, this time the task might be more stringent as one of its main goals is the space walk. Earlier reports said a crew of six astronauts had been chosen for the mission, with three manning the spacecraft and three substitutes. China successfully put two manned spacecrafts into orbit in 2003 and 2005 respectively, becoming the third country to send an astronaut into space after the United States and the former Soviet Union(now Russia).
