mmlu_train_71065 | It was once thought that only time could mend a broken heart, but now scientists think taking a couple of aspirin might be the best way to get over a break-up. Previous studies have shown that people experience feelings of romantic rejection in the same way that they experience physical pain. And Psychology Professor Water Michel, of Columbia University, also believes that the psychological pain of ending a relationship is similar to physical pain, and should be treated like any other injury. "When we speak about rejection experiences in terms of physical pain, it is not just a metaphor - the broken heart and emotional pain really do hurt in a physical way," he said. "When you look at a picture of the one who broke your heart, you experience a pain in a similar area of the brain which is activated when you burn your arm. " Research shows that people who are given a simple painkiller, like aspirin, are able to handle feelings of rejection better than _ given a placebo . 'Take two aspirins and call me next morning' would be a cold-hearted response to a friend's late-night report of fresh heartbreak, but it has a solid basis in the research.

mmlu_train_60457 | Autism spectrum disorder is a developmental disability. People with autism have trouble communicating and with social skills. The U.S. Centers for Disease Control and Prevention says the person also might repeat some behaviors and not want change in their daily activities. Some people with the condition need a lot of help. Others need less. CDC officials say autism affects one in every 68 children in the United States. More boys than girls are believed to have the condition. But the number of cases appears to be growing. It is unclear whether the growing number shows a real increase or comes from more knowledge about this disorder. Symptoms of autism Common signs of autism include trouble making eye contact and a delay in learning how to speak. Some people with severe autism never learn how to talk. Many people with autism also have difficulty understanding facial expressions and the feelings of others. They also have trouble making friends of the same age. Doctors have learned how to recognize autism, but much is still unknown about its causes. Researchers at Harvard University have come closer to finding answers. They found that women exposed to the highest levels of fine particulate air pollution late in their pregnancies are two times more likely to give birth to a child with autism. The findings appeared in Environmental Health Perspectives -- a publication of the National Institute of Environmental Health Sciences. The study found that the women who were around high levels of fine particulate matter air pollution were at highest risk of having an autistic child. The increased risk of these women was two times that of women who lived in areas with low levels of fine particulate pollution. The researchers found that the timing of exposure to pollution was important. They found no increased risk of autism in children whose mothers were around high levels of pollution before becoming pregnant. And the study found air pollution does not seem to increase the risk of children developing autism after they are born. What can pregnant women do? Mr. Weisskopf says pregnant women should avoid air pollution as much as possible. But he warns that other things may increase the risk of autism spectrum disorder. "You can avoid being in extremely polluted cities during pregnancy if possible. You can also choose to go running in a park rather than next to a street. But that said, I think also it's very important to recognize that autism spectrum disorders is a very multi-factorial disorder. And there are lots of reasons why risk could be increased." Autism is believed to result from a combination of environmental and genetic factors. For now, Marc Weisskopf says researchers are trying to identify the exact substances in air pollution that increase the risk of autism. Which is TRUE according to the passage _ ? | [

mmlu_train_32339 | Redwood trees are the tallest plants on the earth,reaching heights of up to 100 meters.They are also known for their longevity,typically 500 to 1000 years,but sometimes more than 2000 years.A hundred million years ago,in the age of dinosaurs,redwoods were common in the forests of a much more moist and tropical North America.As the climate became drier and colder,they declined to a narrow strip along the Pacific coast of Northern Califomia. The trunk of redwood trees is very strong and usually forms a single straight column.It is covered with a soft bark.This bark can be pretty thick,well over two feet in the more mature trees.It gives the older trees a certain kind of protection from insects,but the main benefit is that it keeps the center of the tree harmless from moderate forest fires because of its thickness.This fire resistant quality explains why the giant redwood grows to live that long.While most other types of trees are destroyed by forest fires,the giant redwood actually prospers because of them. Moderate fires will clear the ground of competing plant life,and the rising heat dries and opens the ripe fruit of the redwood,releasing many thousands of seeds onto the ground below. New trees are often produced from shoots,little baby trees,which form at the base of the trunk.These shoots grow slowly,fed by the root system of the "mother'' tree.When the main tree dies,the shoots are then free to grow as full trees,forming a "fairy ring" of trees around the original tree.These trees,in turn,may give rise to more shoots,and the cycle continues. Which of the following is a function of the tree bark as mentioned in the passage? | [

mmlu_train_39186 | Around the world coral reefs are facing threats brought by climate change and great changes in sea temperatures. While ocean warming has been the primary focus for scientists and ocean policy managers, cold events can also whiten corals. A new study by scientists compared damaged to corals exposed to heat as well as cold stress. The results show that cool temperatures can cause more damage in the short term, but heat is more destructive in the long run. Climate change is widely known to produce warming conditions in the oceans, but extreme cold-water events have become more frequent and serious as well. In 2010, for example, coral reefs around the world faced on of the coldest winters and one of the hottest summers on record. During a unique experiment, corals under cold temperatures suffered greater damage in just days compared with heat treated corals. Yet the researchers found that corals were eventually able to adjust to the cold conditions, make their health stable and continue to grow. However, over the long term corals subjected to heat suffered more greatly than those in cold, with evidence of severe whitening and growth stoppage, which leads to death. The coral's ability to adjust to cool temperatures surprised the researchers, who say the study's results show the complexities of monitoring coral health in response to different environmental factors . "Global warming is associated with increases but also decreases of temperatures," said Deheyn, one of the researchers. "Not much has been known about the comparative effects of temperature decrease on corals. These results are important because they show that corals react differently to temperature differences, which is important for future management of coral reefs in the field of climate change."

mmlu_train_30007 | The health-care economy is filled with unusual and even unique economic relationships. One of the least understood involves the peculiar roles of producer or "provider" and purchaser or "consumer" in the typical doctor-patient relationship. In most sectors of the economy, it is the seller who attempts to attract a potential buyer with various appealing factors of price, quality, and use, and it is the buyer who makes the decision. Such condition, however, is not common in most of the health-care industry. In the health-care industry, the doctor-patient relationship is the mirror image of the ordinary relationship between producer and consumer. Once an individual has chosen to see a physician -- and even then there may be no real choice -- it is the physician who usually makes all significant purchasing decisions: whether the patient should return "next Wednesday", whether X-rays are needed, whether drugs should be prescribed, etc. It is rare that a patient will challenge such professional decisions or raise in advance questions about price, especially when the disease is regarded as serious. This is particularly significant in relation to hospital care. The physician must certify the need for hospitalization, determine what procedures will be performed, and announce when the patient may be discharged. The patient may be consulted about some of the decisions, but in general it is the doctor's judgments that are final. Little wonder then that in the eye of the hospital it is the physician who is the real "consumer". As a consequence, the medical staff represents the "power center" in hospital policy and decision-making, not the administration. Although usually there are in this situation four identifiable participants-- the physician, the hospital, the patient, and the payer (generally an insurance carrier or government)-- the physician makes the essential decisions for all of them. The hospital becomes an extension of the physician; the payer generally meets most of the bills generated by the physician/hospital, and for the most part the patient plays a passive role. We estimate that about 75-80 percent of health-care choices are determined by physicians, not patients. For this reason, the economy directed at patients or the general is relatively ineffective. According to the author, when a doctor tells a patient to "return next Wednesday", the doctor is in fact _ . | [

mmlu_train_8411 | It happened one morning 20 years ago. A British scientist Alec Jeffrey came across DNA fingerprinting: He identified the patterns of genetic material that are unique to almost every individual. His discovery changed everything from the way we do criminal investigations to the way we decide family law. But the professor of genetics at the University of Leicester, UK, is still surprised, and a bit worried, by the power of the technology he released upon the world. The patterns within DNA are unique to each individual, except identical twins, who share the same pattern. The ability to identify these patterns has been used to convict(...) murderers and to clear people who are wrongly accused. It is also used to identify the victims of war and settle disputes over who is the father of a child. Jeffrey said he and his colleagues made the discovery by accident while tracking genetic variations . But, within six months of the discovery, genetic fingerprinting had been used in an immigration case, to prove that an African boy really was his parents' son.*In 1986, it was used for the first time in a British criminal case: It cleared one suspect after being accused of two murders and helped convict another man. DNA testing is now very common. In Britain, a national criminal database established in 1995 now contains 2.5 million DNA samples. The U.S. and Canada are developing similar systems. But there are fears about the stored DNA samples and how they could be used to harm a person's privacy. That includes a person's medical history, racial origin or psychological profile. "There is the long-term risk that people can get into these samples and start getting additional information about a person's paternity or risk of disease," Jeffrey said. DNA testing is not an unfailing proof of identity. Still, it is considered a reasonably reliable system for determining the things it is used for. Jeffrey estimates the probability of two individuals' DNA profiles matching in the most commonly used tests at one in a billion. Which is the best title for the passage? | [

However, a new study shows that sea bacteria are good for people. The study finds that a special enzyme from sea bacteria is helpful to humans. It helps people to get more energy from food. To people's surprise, the enzyme is present only in the Japanese. The Japanese traditionally like to eat food rich in seaweed . And the seaweed is rich in this kind of enzyme. However, the enzyme isn't present in all the Japanese. During the study, just 5 out of 14 Japanese had the enzyme. All the Americans studied didn't have the enzyme. "The number is small," said researcher Mirjam Czjzek. "But we can say that this enzyme is present only in the Japanese and not in the North Americans." Then some people think that maybe other people are able to get the enzyme if they eat a lot of seaweed. The study suggests that they collect uncooked seaweed to make their sushi.

But if they use the computer too much, they may end up forgetting the exact strokes of each Chinese character when writing on paper. Experts suggest people, especially students, write by hand more. Do you write by hand more or type more? In Beijing, students start using a computer as early as primary school. And computer dependence is more wide-spread among university students. Almost all their assignments and essays are typed on a computer. All the students interviewed say they usually use a computer. It's faster and easier to correct if using a computer. And that's why computers are being applied more and more often to modern education. But when people are _ computers increasingly, problems appear. "When I'm writing with a pen, I find I often can't remember how to write a character, though I feel I'm familiar with it." "I'm not in the mood to write when faced with a pen and paper." Many students don't feel this is something to worry about. Now that it's more convenient and efficient to write on a computer, why bother to handwrite? Many educators think differently. Shi Liwei, the headmaster of a famous primary school in the capital said, "Chinese characters enjoy both practical and aesthetic value. But those characters typed with computer keyboards only maintain their practical value. All the artistic beauty of the characters is lost. And handwriting contains the writer's emotion. Through one's handwriting, people can get to know one's thinking and personality. Beautiful writing will give people a better first impression of them."

mmlu_train_29334 | Dyslexia is a learning disorder, it interferes with the ability to recognise words, and for some readers to understand what they have read. Experts say dyslexia affects about five to ten percent of the population of the United State. Researchers have long known that people with dyslexia write or read words and letters backwards in the wrong order. But a new study shows that people with dyslexia may have trouble redirecting their attention between senses, from seeing something to hearing something. The study suggests something that might help dyslexic people learn more quickly - play video games. Vanessa Harrar of Britain's University of Oxford led the study. She reported the findings in the journal Current Biology. The study suggests that dyslexic people may have trouble moving quickly from what they read to what they hear. Doctor Harrar calls this a " _ shifting of attention across the senses." "So, if you are trying to read something and then trying to listen to somebody who's reading aloud and you're trying to follow along with what they are reading -- they have to switch their attention from hearing what they are saying to looking at the piece of paper and back again. So we found they have quite sluggish shifting of attention across the senses," said Harrar. In the study, Doctor Harrar tested 17 people with dyslexia, and 19 others without reading problems. The volunteers were asked to push a button as quickly as possible when they heard a sound, saw a light or experienced both together. Doctor Harrar compared the speed of their reactions. She found that people with dyslexia were just as fast as the others when they saw only a picture or heard only a sound. But the dyslexics had a slower reaction time when they heard a sound and saw a picture at the same time. Doctor Harrar feels like playing action video games could help dyslexic people shift from seeing to hearing more quickly. She adds that images in video games force the eyes to move and focus quickly. "Video game types of things pop out of here and there, they move your eyes around the screen quite quickly in response to things quite quickly, and the more you play a video game the faster you get that kind of thing. So, the video game is really training the attention system to move quickly," said Harrar. The study also shows that dyslexic people have the most difficulty going between what they saw and what they heard, this may have an effect on how dyslexic children are taught how to read. When children learn the alphabet,they usually see the letter first and then hear the sound, or they see and hear the letter at the same time. The study shows that dyslexics might learn more quickly if they hear the sound of a letter or word first before seeing it. People with Dyslexia have the following problems except _ . | [

mmlu_train_16790 | The plan: turn Mars into a blue world with streams and green fields, and then fill it with creatures from the earth. This idea may sound like something from a science fiction , but it is actually being taken seriously by many researchers. This suggests the future for the "red planet" will be the main topic for discussion at an international conference hosted by NASA this week. Leading researchers as well as science fiction writers will attend the event. Turning Mars into a little earth has long been a topic in science fiction," said Dr Michael Meyer, NASA's senior scientist for astrobiology ."Now, with scientists exploring the reality, we can ask what are the real possibilities of changing Mars." Most scientists agree that Mars could be turned into a little earth, although much time and money would be needed to achieve this goal. But many experts are shocked by the idea. "We are destroying our own world at an unbelievable speed and now we are talking about ruining another planet," said Paul Murdin from the Institute of Astronomy, Cambridge, UK. Over the past months, scientists have become increasingly confident .They will find Martian life forms.

The appearance of El Nino is known to affect the weather around the world. Scientists still do not completely understand it. Yet they now find they can use it to tell about the future in different areas of the world. One example is the work of two scientists at Columbia University in New York, Mark Cane and Gordon Eshel. A scientist of Zimbabwe , Roger Buckland worked with them. They have found that when El Nino appears, Zimbabwe has little or no rain. This means corn crops in Zimbabwe are poor. The last El Nino was in 1991 to 1993. That was when southeastern Africa suffered a serious lack of rain. The scientists wrote about their recent work in the publication Nature. Their computer program can tell when an El Nino will develop up to a year before it does.

Croman has been photographing ocean waves since 2008,sometimes risking his life to get that perfect shot at the surf break.Despite the risks and certain injuries that come with wave photography, the Hawaii resident,body surfer and former competitive swimmer wouldn't do anything else.The 36-year-old photographer loves the thrill of meeting breaking waves head on,shooting waves as his interest and shooting surfers to pay the bills. The process of photographing waves requires more than just swimming out to where the surf breaks and waiting,he says.The night before a photo shoot Croman checks Surfline.com,a website and the coastal camera network that provides live and predicted ocean weather information,to see what the winds,waves and tide will be like at certain times.Croman has both a primary camera and a backup for emergencies.He goes without a wetsuit and uses heavy duty underwater housing to protect his camera.There is no great way for him to protect himself.He admits there are probably protective clothes he should be wearing,but there is little he could have done to decrease the impact of the 10-foot wave that crashed on top of him. The hardest part of Croman's job is staying calm in the face of breaking waves when his initial reaction is to panic and swim away.At most.Croman will take two to three shots of a single wave."I've shot waves for so many years now that I see the wave in slow movement,"he said.

mmlu_train_54298 | People who are obese have a worse memory than their thinner friends, a small study shows. Tests on 50 people showed that being overweight was linked to worse "episodic memory" or the ability to remember past experiences. The study in the Quarterly Journal of Experimental Psychology argues that a less vivid memory of recent meals may lead to overeating. However, other aspects of memory -- such as general knowledge -- show no signs. Tests on rats have previously shown that with burgeoning waistlines come poorer performances in memory tests, but the evidence in humans has been mixed. Fifty people with a Body Mass Index (BMI) ranging from 18 (healthy) to 51 (very obese) took part in a memory test -- a bit like doing a treasure hunt on your own. They had to "hide" objects at different times and on different scenes displayed on a computer screen. They were later asked to recall what they had hidden, when and where. The results showed obese people's scores were 15% lower than thinner people. Dr. Lucy Cheke, from the University of Cambridge, told the BBC News website, "The suggestion we're making is that a higher BMI is having some reduction on the vividness of memory, but they're not drawing blanks and having amnesia . As a matter of fact, if they have a less strong memory of a recent meal, with a less strong impact in the mind, then they may have less ability to regulate how much they eat later on." Hunger hormones play a huge role in how much we eat, but it has already been recognized that our minds have a key role too. Dr. Cheke concluded, "It is too early to talk in terms of advice, but we are certainly beginning to observe how obesity causes itself to continue." Which of the following is TRUE about the experiment? | [

The American schoolboy, Shubham Banerjee, made a new Braille writer from a Lego tool that lets people create robots. Banerjee has called his new machine the Braigo - a combination of the words Braille and Lego. It costs just $ 350. It works by changing electronic text into Braille and then printing it using a computer or mobile machine. Banerjee designed his Braigo last year for a school science exhibition. Since then, he has caught the interest of Silicon Valley in the USA. The big technology company Intel spent money on Banerjee's machine last November, but they did not say how much money they put in.

mmlu_train_28132 | Not long ago, many people believed that babies only wanted food and to be kept warm and dry. Some people thought babies were not able to learn things until they were five or six months old. Yet doctors in the United States say babies begin learning on their first day of life. The Eunice Kennedy Shriver National Institute of Child Health and Human Development is a federal government agency. Its goal is to determine which experiences can influence healthy development in people. Researchers at the institute note that babies are strongly influenced by their environment. They say a baby will smile if her mother does something the baby likes. A baby learns to get the best care possible by smiling to please her mother or other caregiver. This is how babies learn to connect and communicate with other people. The researchers say this ability to learn exists in a baby even before birth. They say newborn babies can recognize and understand sounds they heard while they were still developing inside their mothers. Another study has suggested that low birth weight babies with no evidence of disability may be more likely than other children to have physical and mental problems. American researchers studied almost five hundred boys and girls. They were born in, or admitted to, one of three hospitals in New Jersey between 1984 and 1987.

mmlu_train_22019 | Researchers around the world have been trying their hand at making better use of the huge amount of wind energy available in nature to produce clean energy. Apart from this, studies are being carried out to harness usable wind energy produced by man-made technologies. One useful source identified by Indian inventor Santosh Pradhan about two years ago is a speeding train, which produces fierce wind that can be transformed into electricity. According to Pradhan's proposal, with a few small improvements in existing trains running in Mumbai, the largest city in India, at least 10,000 megawatts of electricity could be harvested each day. Building on this principle, designers Ale Leonetti Luparinia and Qian Jiang from Yanko Design have created a device called T-Box that harnesses wind energy from speeding trains. T-Box can be placed within the railway tracks. It is half-buried underground between the concrete sleepers , which does not disturb the normal train operating at all. According to Yanko, around 150 T-Boxes can be fitted along a 1,000-meter railway track. A train running at a speed of 200 kph can produce winds blowing at 15 miles a second. Based on this calculation, 150 T-Boxes can produce 2.6 KWH of electricity per day. The T-Box's design won a silver medal in last year's Lite-On Awards and was exhibited last summer at the Xue Xue Institute in Taipei, Taiwan Province. Though the figures look impressive, it is important to remember that the design is still at a conceptual stage and hasn't taken into account issues such as pieces of waste material produced by the device and the efforts and costs involved in the maintenance of the device. We can expect the technology to see the light of the day only after it clears these issues. If so, rail travel, one of the greenest forms of travel, will become greener and more energy-efficient.

But in this case in San Diego, California, scientists for the first time recorded the utterances, did an acoustic analysis and were surprised to find a rhythm similar to that of human speech, Sam Ridgway of the National Marine Mammal Foundation reported on Monday. The sounds marking is quite special : Whales make sounds through the system of the nose, unlike people, who use their throat. So this particular with whale had to make some tricky muscular and blowhole adjustments. "Such obvious effort suggests motivation for relatin", said Ridway, the main author of a study featured in the journal Current Biology. "The sounds we heard were clearly an example of vocal learning by the white whale." The wale, named Noc, died five years ago. Ridgway says that back in 1984, he and others started hearing sounds near the whale and dolphin enclosure that recalled two people speaking in the distance, too far away to be understood. The sounds were later traced to one particular white whale when a diver in its tank came to the surface because he thought he heard colleagues tell him to do so. Noc had lived among dolphins and other white whales and had often been in the presence of humans.

mmlu_train_14404 | Those who spend more pre-bedtime hours using the Internet or watching television are more likely to report insufficient sleep, even though they sleep almost as long as people spending fewer pre-bedtime hours in front of a computer or television screen, survey findings show. "While many people use electronic media, say, the Internet, it should be noted that the longer media use before sleep can trigger (self-perceived) insufficient sleep," lead researcher Dr Nakamori Suganuma, of Osaka University, Japan, told the reporter. He and colleagues obtained data on self-perceived sleep problems and the use of electronic media prior to bedtime from 5,875 altogether Japanese respondents in two separate Internet-based surveys. Their findings are published in Sleep and Biological Rhythms. Nearly half of the respondents associated their problem with electronic media use before bedtime. Longer electronic media users were also more likely to report insufficient sleep. "Overall, 29% of light users (less than 1.5 hours) listed electronic media use as a possible cause of their insufficient sleep. By comparison, 40% of medium users (1.5 to 3 hours) and 54% of heavy users (more than 3 hours) said the same. However, longer Internet and television use before bedtime did not _ less actual sleep. While heavy users averaged about 3 more hours in front of computer or television screens than light users, the heavy users averaged only about 12 minutes less pre-workday sleep time than light users. Notably, Suganuma said, "Internet use affected self-perceived insufficient sleep more than TV watching not only in younger Internet users but also in middle-aged or aged Internet users." Up to 38% of the respondents listed accessing the Internet far into the night as a possible cause for their sleep disturbance, while about 25% said watching television far into the night caused it. The findings suggest that while heavy computer and television use before bedtime has a small effect on sleep duration, it may have a more significant effect on "sleep demand and sleep quality," Suganuma notes. Heavy computer and television user before bed time are more likely to be _ than light ones. | [

mmlu_train_64532 | One day, I received a call from a colleague. He was about to give a student a zero for his answer to a physical problem ,while the student claimed a perfect score. I was elected as their arbiter( ).I read the examination problem: "Show how it is possible to determine the height of a tall building with the aid of a barometer ." The student had answered: "Take the barometer to the top of the building,attach a long rope to it,lower it to the street,and then bring it up, measuring the length of the rope. The length of it is the height of the building. " The student had really answered the question completely ,but the answer didn't confirm his competence in physics. I suggested the student try again. I gave him six minutes to answer the question, warning that the answer should show some knowledge of physics. Five minutes later, he said he had many answers and clashed off one, which read: "Take the barometer to the top of the building and lean over the edge of the roof. Drop the barometer, timing its fall with a stopwatch. Then, use the physical formula to calculate the height of the building. " At this point, my colleague had to accept it, and then the student made almost full marks. I couldn't help asking the student what the other answers were. He listed many others ,and then added5"Probably the best is to take the barometer to the. administrator and said to him,' Sir, here is a fine barometer. If you tell me the height of the building, I will give it to you.," Then, I asked the student if he really did not know the conventional answer to this question. He admitted that he did ,but said that he was fed up with high school and college instructors trying to teach him how to think. The name of the student was Bohr who later was famous all over ,the world. He won the Nobel Prize for Physics in 1922. We can learn from the passage that _ . | [

The health program is to reduce the amount of fat students today and in the future. The program will get families, schools, newspapers, magazines and TVs to join together and deal with the students' obesity so that students will be at a healthier weight. The program includes: Food stores should sell healthier foods. Schools should serve healthier meals with less fat and should also offer gym classes. The lady is trying to fight the students' obesity all over the country because it can cause illnesses and higher health cost. She wants the students to eat right, exercise more and control their weight. She also wants the students to understand it is important to have less sweet food, and drink water, milk and fresh juices, but not to choose cokes. At the same time she has also set a good example by planting a vegetable garden. She hopes that the garden will encourage more people to plant one, too. The health program is really helpful to the students today and in the future. As she says, we cannot always build the future for youth, but we can build our youth for the future.

mmlu_train_20300 | Adding math talk to story time at home is a winning factor for children's math achievement, according to a new research from the University of Chicago. The study from psychologists Sian Beilock and Susan Levine shows a marked increase in math achievement among children whose families used Bedtime Math, an iPad app that delivers engaging math story problems for parents and children to solve together. Even children who used the app with their parents as little as once a week saw gains in math achievement by the end of the school year. The app's effect was especially strong for children whose parents tend to be anxious or uncomfortable with math. Previous research from this group has demonstrated the importance of adults' attitudes about math for children's math success. For example, a recent study found that math-anxious parents who help their children with math homework actually weaken their children's math achievement. The new findings demonstrate that structured, positive interactions around math at home can cut the link between parents' uneasiness about math and children's low math achievement. "Many Americans experience high levels of anxiety when they have to solve a math problem, with a majority of adults feeling at least some worries about math," said Beilock, professor in Psychology and author of Choke, a book about stress and performance. "These math-anxious parents are probably less likely to talk about math at home, which affects how competent their children are in math. Bedtime Math encourages a dialogue between parents and kids about math, and offers a way to engage in high-quality math interactions in a low-effort, high-impact way." Study participants included 587 first-grade students and their parents. Families were given an iPad installed with a version of the Bedtime Math app, with which parents and their children read stories and answer questions involving math, including topics like counting, shapes and problem-solving. A control group received a reading app that had similar stories without the math content and questions related to reading comprehension instead. Children's math achievement was assessed at the beginning and end of the school year. Parents completed a questionnaire about their nervousness with math. The more times parents and children in the math group used the app, the higher children's achievement on a math assessment at the end of the school year. Indeed, children who frequently used the math app with their parents outperformed similar students in the reading group by almost three months in math achievement at year's end. The previous study found that _ . | [

Taking the bus to school is quick, easy and free in most college towns. You won' t have to locate or afford a place to park either. It' s also a good way to be environmentally aware. * Save pennies on books by waiting until class starts. You might not even need all of the recommended books. New textbooks cost an arm and a leg. Try buying used textbooks -- it' s a surefire way to save money and serves the purpose as well. * Do never look at college life as an endless series of parties and social activities. But there is a whole lot more to college if you're serious about graduating. Having a good college experience is all about balancing work and fun. * Be mindful of your diet. Make healthy food choices and watch what you eat. Avoid foods that are processed or high in sugar. The "freshman 15"is real. Many college students gain at least 15 pounds during their freshmen year. * While electives can be helpful when figuring out your major, you shouldn't entirely rely on them.

mmlu_train_47980 | Dear iPhone 4 Users, The iPhone 4 has been the most successful product in Apple's history. It is the best smartphone ever, and most users have told that they love it. So we were surprised when reading reports of reception problems, and we immediately began researching them. To start with, holding tightly almost any mobile phone in certain ways will reduce its reception by 1 or more bars of signal strength. This is true of iPhone 4, iPhone 3GS, as well as many other phones. But some users have reported that iPhone 4 can drop 4 or 5 bars when tightly held in a way. This is a far bigger drop than normal, and as a result some have said the iPhone 4 has a faulty antenna design. Upon research, we find that the formula we use to calculate how many bars of signal strength to display is totally wrong. Our formula usually mistakenly displays 2 more bars than it should for a given signal strength. The big drop in bars is because the high bars were never real in the beginning. We will give a free software update to correct the formula. This software update will also be available for iPhone 3GS. If you are not fully satisfied, you can return your undamaged iPhone to any Apple Retail Store or the online Apple Store within 30 days of buying and get all your money back. Thank you for your patience and support. Apple The iPhone 4 drops more bars than normal when tightly held because of _ . | [

mmlu_train_22738 | Dr Asim Syed, 32, has performed more than 100 operations at London's Hammersmith Hospital in the country's busiest transplant unit, but never imagined that he would one day become a donor himself. He stepped forward when was told his 64-year-old mother might be dead within months unless she got a new kidney . The worried surgeon brought her to London to be cared for at his hospital. However, it was not all plain sailing. Tests showed Dr Syed was the wrong blood group, so the only way was to go through a special blood-washing process. He consulted colleagues about that, but they didn't agree, because the risk of rejection is still too high. Dr Syed and his mother were then advised to consider a new way of donating and receiving, called an organ-paired. That is, Dr Syed donated his kidney to an unknown person and another donor in the chain was a successful match for his mother. The chain of three transplants took place at the same time on July 31 with Dr Syed's kidney going to a recipient in the Midlands and Mrs. Syed receiving her kidney from a person in the south of England. Just hours after donating his own kidney, Dr Syed found himself recovering in bed next to his mother. Mrs Syed said, "When I came round from my operation Asim was in the next bed and the first thing he said was, 'Mum now all your worries are over.' Tears fell down." Now mother and son are recovering well with Dr Syed already back at work. Mrs. Syed is staying with him for several months while the hospital monitors her progress.

mmlu_train_36285 | It is an aerial performance far beyond the capabilities of even the most complex modern aircraft: landing upside down on a ceiling. But it is routine business for bats, and now scientists have learned precisely how they do it. Brown University scientists observed two species: Seba's short-tailed bat and the lesser dog-faced fruit bat. They tracked their motions using three high-speed video cameras taking images at 1,000 frames per second, and studied weight distribution in the bats' body and wings. They found that by flapping both wings while folding one of them just a bit toward their body, a bat can shift its centre of mass to perform a midair flip in order to land on a ceiling. "Flying animals all move skillfully constantly as they fly through a three-dimensional environment," Brown biology and engineering professor Sharon Swartz said. "Bats employ this specific technique every time they land, because for a bat, landing requires reorienting from head forward, back up, belly down, to head down, toes up." When approaching their touchdown spot, bats are not flying very quickly, making it difficult to gather the type of aerodynamic forces produced by pushing against the air that could help position them for an upside-down landing. But their heavy wings enable them instead to create inertial forces to adjust themselves in midair. Swartz said bats, as nocturnal animals, are generally not fully appreciated as skilled pilots. "People have many opportunities to observe birds and insects flying, but the bat world is hidden in the night. The more we observe flight behavior in bats, the more we are impressed," Swartz said. Why aren't bats generally recognized as skilled pilots? | [

mmlu_train_7585 | Since the development of the Internet, men and women have frequented the information superhighway for the purposes of research and social networking. Recently, developments in fourth-generation networks and associated communication devices such as smart phones and smart tablets such as the BlackBerry PlayBook have allowed social networking technology to take a giant leap forward. In this fast-paced world it is often difficult to stay in contact with friends, family, and coworkers, due to the fact that work and education often cause people to move to a number of different locations after spending only a short time in each place. Many people have accepted the fact that family members may only see each other a few times a year. Smart phones are equipped with their own wireless fidelity connections, which allow them to connect to Internet-based social networking sites. The BlackBerry PlayBook allows users to make hands-free telephone calls while on the go, and it has a host of other interesting functions. At the same time, PlayBook users can still surf the same old websites, and check e-mail through the Internet connection. However, instant messaging and e-mail are quickly becoming outdated because of the PlayBook's video chat capabilities. This particular feature makes the PlayBook an excellent choice for those families who find themselves separated over long distances. Someone once said that a picture was worth a thousand words. Thanks to the PlayBook's video chat capabilities, users of 4G devices can gain a measure of the physical contact that all human beings hope for, because of the device's ability to deliver the streaming real-time video to their users. Therefore, people can see the person they are speaking to, and read their facial expressions as well as their body language, while also hearing their actual voices in stereo sound .

mmlu_train_57052 | Almost everyone is afraid of something --- snakes, heights, public speaking and so on. It is normal and can even be helpful to experience fear sometimes. In dangerous situations, fear can keep our bodies alert so that we can act quickly to protect ourselves. But for some people, fear develops into a "phobia", which is a strong and unreasonable fear of something. For example, the majority of us feel a little scared when looking down from a tall building. But people with height phobia may have trouble breathing, feel dizzy or turn down a great job just because the company is on the 20th floor. Phobias can prevent you from living a normal life. "People with spider phobia would stay out of their home or dormitory room for days if they thought a spider was present," Katherina Hauner, a researcher at Northwestern University, US, told ABC news. This is why scientists have been trying to find a cure for this disease. Since fear comes from experience --- from what we are told, what we see others experience and what happens to us --- some scientists think if they can "rewrite" these unpleasant memories, they might be able to help people overcome their phobias. In a study by Hauner and other scientists, participants with spider phobia were asked to first touch a spider with a paintbrush. Seeing that it was not actually dangerous, they then tried touching it while wearing a glove. Finally, they could hold it with their hands. Certain medicine has also been found to be helpful. Back in 2010, researchers at the University of Hiroshima, Japan, injected a special medicine into a fish --- who was afraid of light --- to turn off the fear center in its brain. From then on, the fish no longer feared light. While the search for solutions to phobias is making great progress, it's an open question whether getting rid of fear is good. Some people want to use these methods to make soldiers fight harder in wars by taking away their sense of fear. Dave Smithson of the charity Anxiety UK thinks that's a bad idea.
