mmlu_train_53732 | It's 4 am, and Danilo C. Dequina is already awake. Holding a flashlight and a bucket, he is walking in the pre-dawn darkness along the shore of Old Poblacion Beach in the town of Maitum, Sarangani, in the far south of the Philippines. A few minutes later, he spots a patch of sand that appears to have been disturbed by a turtle. Dequina studies the area carefully, figuring out where the eggs have been buried, and then starts digging slowly. After clearing away several centimeters of sand, he uncovers a large group of eggs, roughly the size of ping-pong balls. He picks them up and puts them in the bucket. Dequina carries the eggs to his hatchery , some 50 meters away from the seashore. The hatchery is really just a sandy patch of land under the coconut trees enclosed by a black fence. It is here that he buries the turtle eggs he has collected. Today, Dequina scoops a hole, puts the eggs in it, and covers them with sand. After 45 to 70 days, the eggs will hatch. Dequina will then carry the hatchlings to the shore, and release them into the sea. He admits to feeling sorrow as he sets the hatchlings free -- most are hunted down by natural predators, and just one percent survive to adulthood. According to the Philippine Department of Environment and Natural Resources (DENR), eight species of sea turtles face extinction, including four that come to the shores of Sarangani to lay their eggs -- the Hawksbill, Olive Ridley, Loggerhead and Green Turtles. After learning about their plight , Dequina attended a DENR training session on turtle conservation and decided to take action. He helped the local government to set up the Pawikan Nesting Sanctuary next to his house in 2003. The hatchery drew the attention of the locals. "They started to change their attitudes towards sea turtles," 52-year-old Dequina says. "If they see turtle eggs, they will either bring them to me or inform me of the nesting places." Over the past ten years, more than 3,000 hatchlings have been released to the ocean. Dequina walks along the shore to _ . | [

mmlu_train_68263 | January 16, 2014 - We know the saying "The early bird gets the worm", but today you're going to learn about the interesting saying "The early fish gets the bird." An African tigerfish was seen jumping out of the air and catching a flying bird. The African tigerfish has bright red fins and very sharp teeth. There have been rumors this kind of fish preys on birds since the 1940s, but no one was able to catch _ . "The whole action of jumping and catching happens so quickly that after we saw it, it took all of us a moment to really understand what we had just seen," said Nico Smit from Environmental Sciences and Management at North-West University. Smit and his research team saw it at a lake in the Mapungubwe National Park in South Africa during summer. They found about 20 fish feeding on birds in the morning. Those birds may be out early to look for food, but we will never know for sure! Which of the following is true according to the passage? | [

mmlu_train_39949 | Although travelers can try dishes from around China and the globe in well-known food cities like Beijing and Shanghai, it is outside these major metropolises where a world of exciting Chinese cuisine awaits the true foodie . With this in mind and after three years of living in China and writing about Chinese food, I started a six-month journey with my husband and two daughters. Here are four of the eight most amazing Chinese food cities I've come across so far. The list is in no particular order. 1. Chengdu, Sichuan Province Crowned as Asia's first UNESCO City of Gastronomy in 2010, Chengdu is best-known for its fiery hot pot and spicy dishes, which are characterized by the use of Sichuan pepper and are usually layered with salty, sour and sweet flavors. There are also dishes that aren't spicy at all, such as beer-braised duck. Hot pot is as _ in the city as the smell of chili. At Zigong Delicious Hotpot, the house specialty tiaoshui wa is a cauldron of fiery chili to which vegetables, noodles or other meats can be added. For a real taste of Sichuan's signature pepper, hua jiao, spend a morning at the Chengdu Spice Market where the locals sell and buy it by the sack. 2. Lanzhou, Gansu Province Synonymous in the minds of food-lovers with hand-pulled beef noodles, Lanzhou also has one of the liveliest street food night markets in China. Just west of the city center, the buzzing Zhengning Road bazaar houses more than 100 street food stalls. Available is a broad selection of hot and cold dishes with emphasis on local Hui cuisine. No trip to Lanzhou is complete without feasting on noodles at Wumule Penhui, the 2012 winners of Lanzhou's annual pulled noodle competition. The halal restaurant makes noodles spicy enough to satisfy even the most hardened heat-seekers. 3. Guangzhou, Guangdong Province The birthplace of Cantonese food, Guangzhou is thought by many as the best place to eat in China. The city of 12 million has a passionate food culture, with equal excitement reserved for the opening of a hole-in-the-wall congee joint and a high-end restaurant. The local cuisine is characterized by fresh clean flavors , seafood, barbecued meats and the wonderful tradition of yum cha, which is tea drinking accompanied by dumplings and small dishes. Congee is the way locals love to start their day, and one of the most popular vendors is Ru Xuan Sha Guo Zhou. Here, one can get a bowl of signature seafood congee any hour of the day. Roast meats are Bing Sheng's most popular order--their roast goose is marinated with five-spice, boiled, air-dried, then roasted by a flame oven to give a crisp skin. For something more home style and removed from the madness of downtown, head to Ji Cun for steamed chicken and simple farmer-style dishes. 4. Shaoxing, Zhejiang Province This ancient canal city is home to huangjiu, an amber-colored rice wine that's important in Chinese cooking. Open since 1894, the dining chain is known by almost every Chinese for its appearance in early 20th century novels by Chinese literati Lu Xun. Xianheng's delicacies include crispy-skinned chicken, smoked red dates in rice wine, beans flavored with fennel , and crispy bream in rice wine. Fried fermented tofu is also a local specialty, which is available all over town at small street stalls including one just outside Xianheng. If a fresh clean flavor is to a foodie's taste, which couple of cities is he likely to make a trip to? | [

mmlu_train_57070 | A team of US psychologists have found that talking to another person for ten minutes a day helps with memory. "Socializing is just as effective as more traditional kinds of mental exercise in memory and intellectual performance," Oscar Ybarra, a psychologist at the University of Michigan Institute for Social Research, said in a statement. In one investigation, they analyzed data on 3610 people, aged 24 to 96. They found that the higher their level of social interaction , the better their cognitive functioning. Social interaction includes getting together or having phone chats with relatives, freinds and neighbors. In another experiment, the researchers conducted lab tests on 76 college students, aged 18 to 21, to evaluate how social interactions and intellectual exercises affected the results of memory and mental performance tests. The students were divided into three groups: the social interaction group had a discussion of a social issue for 10 minutes before taking the tests; the intellectual activities group completed three tasks (including a reading comprehension exercise and a crossword puzzle) before the tests; and a control group watched a 10-minute clip of the Seinfeld television show. "We found that short-term social interaction lasting for just 10 minutes improved participants' intellectual performance as much as engaging in so-called 'intellectual' activities for the same amount of time," Ybarra said. The study was expected to be published in the February issue of the journal Personality and Social Psychology Bulletin. What's the main idea of the passage? | [

mmlu_train_46012 | For centuries,mankind and dogs have suffered from a communication failure.We can tell dogs what we want them to do and sometimes they comply,but we've always struggled when it comes to understanding the true meaning of their barks and whimpers.There is exciting news now-a dog translator has been invented to help you communicate with your furry friend. Researchers at North Carolina State University have fashioned some kind of miracle dog translator body harness .What's special about it is that it doesn't just rely on the dog's vocalizations to interpret what Fido is banging on about. Oh no-this miracle harness reads and interprets the ordinary dogs'body language as well,giving us a full two-way dog communication experience. Researcher David Roberts says:"Dogs communicate primarily through body language,and one of our challenges was to develop sensors that tell us about their behavior by observing their posture remotely." Sensors on the harness monitor the dog's heart rate and body temperature and software builds up a vocabulary,letting the human know what the dog is feeling. What would dogs say if they could talk to us?The human can even communicate back through the harness thanks to vibration motors,supposedly by tapping into the dog's senses so that it can understand what you're trying to say to it. The dog harness is designed for dogs involved in search and rescue and other front-line work,but it's got us dreaming of a beautiful future,one where humans and dogs can co-exist as equals,with the dog able to fully express itself at all times. For what purpose is the dog harness designed? | [

mmlu_train_36549 | Angry Birds is a video game developed by Finnish computer game developer Rovio Mohile. Inspired primarily by a sketch of stylized wingless birds, the game was first released for Apple's mobile operating system in December 2009.Since then, over 12 million copies of the game have been purchased from Apple's App Store. With its fast-growing popularity worldwide, the game and its characters---angry birds and their enemy pigs---have appeared in television programs throughout the world. The Israeli comedy A Wonderful Country ,one of the nation's most popular TV programs, satirized recent failed Israeli-Palestinian peace attempts by featuring the Angry Birds in peace negotiations with the pigs. Clips of the segment went _ getting viewers from all around the world. American television hosts Conan O'Brien ,Jon Steward ,and Daniel Tosh have referenced the game in comedy sketches for their programs, Conan, The Daily Show, and Dash. O. Some of the game's more famous fans include Prime Minister David Cameron of UK, who plays the iPad version of the game, and author Salman Rushdie, who is believed to be "something of a master at Angry Birds." Angry Birds and its characters have also been featured in advertisements in different forms. In March 2011,the characters began appearing in a series of advertisements for Microsoft's Bing search engine. In the same year, Nokin produced an advertisement in Austin, Texas that included the game's characters on a downtown building for its new mobile phone. Later, a T-Mobile advertisement filmed in Spain included a real-life mock-up of the game in a city center .Nokin also used the game in Malaysia to promote an attempt to set a world record for the largest number of people playing a single mobile game. Angry Birds has even inspired works of philosophical analogy .A five-part essay with the title" Angry Birds Yoga ---How to Eliminate the Green Pigs in Your Life" was written by Giridhari Dasar in Brazil ,utilizing the characters and game play mechanics to interpret various concepts of yoga philosophy. The piece attracted much media attention for its unique method of philosophical presentation. Which of the following is TRUE about the use of Angry Birds according to the text? | [

mmlu_train_43317 | Dogs wag their tails in different directions depending on whether they are excited and wanting to move forward or threatened and thinking of moving back, a study has found. Researchers in Italy examined the tail wagging behaviour of 30 dogs, catching their responses to a range of stimuli with video cameras. To conduct the study they chose 15 male dogs and 15 female ones aged between one and six years. The dogs were all family pets whose owners had allowed them to take part in the experiment at Bari University. The dogs were placed in a large wooden box with an opening at the front to allow for them to view various stimuli. They were tested one at a time. The researchers led by Professor Giorgio Vallortigara of the University of Trieste found that when the dogs were shown their owners--a positive experience--their tails wagged energetically to the right side. When they were shown an unfamiliar human they wagged to the right, but with somewhat less enthusiasm. The appearance of a cat again caused a right-hand side wag, although with less again. The appearance of a large unfamiliar dog, similar to a German shepherd, changed the direction of tail wagging to the left. Researchers supposed the dog was thinking of moving back. When the dogs were not shown any stimuli they tended to wag their tails to the left, suggesting they preferred company. While the changes in the tail wagging were not easily noticed without the aid of video, it was thought that the findings could help people judge the mood of dogs. Computer and video systems, for example, could be used by professional dog trainers to determine the mood of dogs that were required to approach. The video cameras were used to catch the dogs 'responses because _ . | [

"Even though I have many difficulties in my life, I don't want people to feel bad for me," Sam said during a TED talk. Progeria affects approximately one in every 4 million to 8 million newborns. Right now, there are only about 200 children living with it worldwide. The genetic change tied to _ causes those with the disease to produce the protein progerin, which blocks normal cell function. His view on life is extremely inspiring. He had to face challenges no one else could even dream of. As children with progeria age rapidly, they suffer from a loss of body fat and hair and an inability to gain weight. That didn't keep Sam down, though. "All in all, I don't waste energy feeling bad for myself," Sam said. "I surround myself with people that I want to be with. And I keep moving forward." This boy from Boston was so amazing, famous people and athletes wanted to take him under their own. Last Saturday night could have been an amazing moment for Sam. One of his favorite teams, the New England Patriots, wanted to make him their honorary captain during a playoff game. Instead, it just was't meant to be. Sam passed away before he had a chance to stand next to his team, so they held a moment of silence before the game for him. Sam's unbelievable view on life, and his deep effect on others, is hard to forget. He was presented with so many challenges in life but he wasn't afraid to face them.

mmlu_train_49774 | Research has shown that music has an important effect on one's body and psyche . In fact, there is a growing field of health care known as music therapy, which uses music to treat diseases. Even hospitals are beginning to use music therapy. This is not surprising, as music affects the body and mind in many powerful ways. Research has shown that quick music can make a person feel more alert, while slow music can produce a calm, deep thinking state. Also, research has found that music can change brainwave activity levels. This can help the brain to change speeds more easily on its own as needed, which means that music can bring lasting benefits to your state of mind, even after you've stopped listening. Breathing and heart rates can also be influenced by music. This can mean slower breathing, slower heart rate. This is why music and music therapy can help reduce the damaging effects of long-term stress, greatly promoting not only relaxation, but health. Music can also be used to bring about a more positive state of mind by helping to keep worries away.

mmlu_train_54858 | When Sally Ride was ten years old, she had no idea that she would some day grow up to be one of America's first woman astronauts. In fact, if you had asked her then what wanted to be, she would have said, " I want to play shortstop for the Los Angeles Dodgers." Sally collected baseball cards by the boxful, and she knew the name and batting average of every player in the National League. But major league baseball didn't seem much of a possibility for a girl, even an athletic one like Sally, so her father and mother talked her into taking tennis lessons when she was twelve. At first she hated to trade in her baseball bat for a tennis racket, but it wasn't long before she started to win tournaments in her new sport. " Tennis became much more fun when I started winning," Sally remembers. Soon a row of trophies replaced her box of baseball cards, and tennis star Billie Jean King replaced Dodger shortstop Maury Wills as her sports idol. Sally first became interested in the space program in 1962 when astronaut John Glenn orbited the earth in his Mercury space capsule. Sally was ten years old at the time, but she remembers the launch and the splashdown as if they happened yesterday. The girl who used to memorize batting averages became a space fan. She quickly learned the name of every NASA astronaut(there were only eight of them in 1962), the date of every launch, and the name and number of every spacecraft from Freedom 7 to Skylab 3. She could tell you the speed of light (186,300 miles per second), the distance to the moon (238,860 miles), and the names of the three nearest stars( the Sun, Alpha Centauri, and Barnard's Star). By the time she was sixteen, Sally had decided to become an astrophysicist, a scientist who studies space. She had also become a nationally ranked tennis player. She remembers yawning through an important tennis match on June 20, 1969, after staying up all night to watch Neil Armstrong's first steps on the moon. Sally lost the match. As Sally got older, many of her friends started playing professional tennis. Some of them tried to talk her into quitting school to join them on the professional tennis circuit. But Sally said no. " Black holes are more interesting to me than backhands," she told them. Now she knows that she made the right choice, but in 1970 Sally had no way of knowing that NASA would open the space program to women. From the story we know that Sally _ . | [

You have your laptop computer with you and you connect it to a wireless access point and access the Internet. Then you send your email. This wouldn't have been possible if there were no wireless Internet for laptops. Wireless Internet has come into our life in so many ways that we don't even realize what a necessary part it has become of our day-to-day lives. How do we connect to a wireless Internet service for laptop computers? There are two ways to do this. They are Wi-Fi connection and Bluetooth connection. Wireless networking is very easy. You just switch on the Wi-Fi button that has been provided in the laptop for Wi-Fi scanning. Once that is done, the computer will connect to the Internet. An interesting fact about Wi-Fi networking is that you can create a network between similar wireless equipment. Consider a situation where you and your friend both have Wi-Fi laptops, and there is some data you want to exchange. Traditional networking architecture demands that you have a wireless router . But the beauty of Wi-Fi networking technology is that you can set up a network between you and your friend's laptop, and share all the data you want. Broadband Internet connection is typically preferred by any user as it provides better speed for Internet surfing. Up until the invention of 3G mobile phones, Internet speed on mobile phones was very slow. 3G has the promise of changing the entire face of broadband technology. Just imagine browsing at speeds of more that 2MB per second. To give you a measure of the speed, 3G enables you to watch high quality live videos on the Internet. It is amazing to see how technology changes and the rate at which it changes. There may come a time when you may be able to browse using mobile wireless Internet for laptops anywhere in the world.

mmlu_train_11937 | The Future of Dairy Farming: Robot Milkers The future has arrived at a dairy farm in about an hour by car from WashingtonD.C. A robot is milking cows. It is milking time at Woodbourne Creamery in Mt. Airy, Maryland. The cows are standing in line for a turn at the robot. John Fendrick is the owner of the farm. He inspects the progress of the animals by looking at a computer screen. That is all he has to do."The door opens up, they walk in, and they get milked. The door opens up, and they walk out." The robot does all the work. It uses a laser to find each teat -- the place on the cow where the milk comes out. The robot then cleans the teat and connects a milking tube toit. The robot also tests the milk for possible contamination . If it finds a problem, it rejects the milk. When the amount of milk coming out of the cow slows, the machine knows to stop, and sends the cow on its way. Milking robots are becoming popular among dairy farmers in the United States, Europe and Australia. John Fendrick says the robots have changed life on a dairy farm."You are given the freedom back. So it allows me or the people working for me to actually do other things on the farm." Most dairy farmers must milk their cows two times a day, early in the morning and late at night. The animals are milked every day in good weather or bad. But Mr Fendrick's cows do not follow such a schedule. They stay in the field until they want to be milked by the robot. Some of them come to be milked in the middle of the night. Mr Fendrick doesn't even need to be there to watch his cows being milked. He can watch from his telephone. He can learn when each cow was milked and how much she produced. He can also learn if a cow has not been milked for a long time. The cow milking robot is not low-cost technology. Mr Fendrick paid more than $150,000 for it. But he notes, paying someone to milk the cows is also costly."In three years, I will have paid off the difference with this, and I don't have to be the person who's always on call to milk. The fact is that we have a life, and our cows are able to function without us -- to us, it's well worth the money." And he says that is a good thing."I don't like to milk."With the robot, he can turn his attention to other things. He gets about 475 liters of milk a day, and he never has to touch a cow. The reason why Mr Fendrick doesn't even have to be on the farm is that . | [

mmlu_train_63938 | On May 18,1969,NASA astronauts Thomas Stafford,John Young,and Eugene Cernan boarded the Apollo 10 lunar module --the fourth manned mission in the US Apollo Space program and only the second after Apollo 8 to circle the moon.Its mission was to circle the moon and thoroughly test the components and procedures to pave the way for the first lunar landing. The mission went perfectly without incident--at least that's what every one believed. However, that view has changed since February 22, after NASA released a digital recording of strange music heard by the space travelers.Then as they were re-entering the zone where they could communicate with ground control.One of the astronauts asked if they should report it.In response, Stafford expressed his doubts if anyone would even believe them.But they needn't have worried. When NASA experts listened to the recordings,they thought the strange sounds were radio interference. Michael Collins--the Apollo 11 pilot--said that the only reason why he was not shocked upon hearing them was that he had been forewarned by NASA officials.Collins also said that the music stopped as soon as the lunar module landed on the moon. So why did it take NASA over 40 years to release the digital recording of the awful music only after it was featured in a recent television series NASA's Unexplained Files? The US Space Agency says they have not been hiding them.In the press release that accompanies the release of the recording,NASA officials state,"The Apollo 10 audio clips were uploaded in 2012, but the mission's sound recordings have been available at the National Archives for anyone that wanted to hear them since the early 1970s." Eugene Cernan, Apollo 10's pilot who heard the sounds first,also released a statement saying,"I don't remember that incident excited me enough to take it seriously.It was probably just radio interference.Had we thought it was something other than that,we would have briefed everyone after the flight. We never gave it another thought." While most people are ready to accept this logical explanation,there are some that believe otherwise. They guess the music proves the presence of aliens. Among them is Apollo 15 astronaut Al Worden,who thinks the sounds came from a source in outer space.In the episode of NASA's Unexplained Files, which discusses the origin of the strange music,the astronaut says, "Logic tells me that if there was something recorded on there,then there was something there."

Your task: find the missing person; provide emergency medical treatment, if necessary; and be prepared to operate 48 hours on your own with only the supplies you carry. Sounds like some kind of film's plot? Not if you're a member of the Arapahoe teen rescue patrol in the suburbs of Denver. About 25 teen guys and girls are active members of this search, rescue and emergency organization, and they know firsthand that you don't have to be an adult to save lives. These 9th-through-12th graders are the real deal when it comes to emergency services. In fact, they're the only teen-commanded patrol in the nation. Sure they have adult advisers to turn to if necessary, but in the field it's a teen patrol officer calling the shots -- sometimes even giving direction to adults. Members are trained in rock-high-angle,swift-water and avalanche rescue , winter and alpine operation , wilderness life support and emergency care, among other skills. They also regularly ride along with the local fire and police departments, providing support such as security details and evidence searching. When asked what qualities make a good patrol member, founder and president Stan Bush named good physical conditioning and an interest in helping people.

According to the Sleep Council, "junk sleep" could compete with eating unhealthy junk food as a main worrying lifestyle for parents of teenage children. Among the l, 000 students aged 12 t0 16 who were tested in the survey, 30 percent just slept for 4 to 7 hours a day. Almost a quarter said they fell asleep, more than once a week, while watching TV, listening to music or using other electronic gadgets. "This is a quite worrying trend ", said Dr Chris Idzikowski of the Edinburgh Sleep Centre. "What we are seeing is the appearance of terrible junk sleep - sleep that is of neither the length nor the quality it should be." Nearly each of the teenagers had a phone, music system or TV in his or her bedroom, with around two-thirds owning all three. Almost one in five of the teenage boys said the quality of their sleep had been influenced by leaving their TVs or computers on. The survey also found that 40 percent of youngsters felt tired each day, with girls aged 15 to 16 feeling the worst. "Teenagers need to wake up to the fact that to perform well. They need to do something about their sleep. I'm shocked that so few teenagers have noticed ," said Idzikowski. Which of the following kinds of sleep is thought to be "junk sleep"? | [

mmlu_train_29905 | If you have a fever, headache and runny nose, you might go to Google and type in the words "flu symptoms" to see whether you've come down with the disease. Google knows that you might do something like that, and it also knows which state you're in if you are in the United States. Now, it's putting that information together in a tool that could find out flu outbreaks faster than traditional systems currently in use, according to CNN report. It is called Google Flu Trends. "What's exciting about Flu Trends is that it lets anybody---doctors, health officials, moms with sick children---learn about the current flu activity level in their own state based on the data that's coming in this week," said Jeremy Ginsberg, the lead engineer who developed the tool. The tool operates on the idea that there's likely to be a flu outbreak in states where flu-related search terms are currently popular. To test the accuracy of the data, Google compared its figures against statistics filed over the past five years by the US Centers for Disease Control. It has a network of 1,500 doctors across the US who provide weekly reports on the number of patients complaining of flu-like symptoms. "We found we could highly accurately estimate what the flu activity levels would be in those years," Ginsberg said. They also found that the Google statistics, which can be gathered daily, were up to two weeks ahead of the government's data. The government's data took time to collect because it came from so many doctors. The ability to speed up the response of health services could prove invaluable when a serious outbreak happens. The results of Google's comparisons with official health statistics will be published in the science journal Nature. Google hopes to extend the service to other countries, and may in time include other illnesses. At present, the flu data is given for each of the 50 American states.

mmlu_train_59627 | Less TV Reduce Kids Weight PALO AITO, California--"Switching off the television may help prevent children from getting fatter--even if they do not change their diet or increase the amount they exercise," US researchers said last week. A study of 192 third and fourth grades, generally aged eight and nine, found that children who cut the number of hours spent watching television gained nearly two pounds (0.91 kg) less over a one-year period than those who did not change their television diet. "The findings are important because they show that weight loss can only be the result of a reduction in television viewing and not any other activity," said Thomas Robinson, a pediatrician at Stanford University. " American children spend an average of more than four hours per day watching television and videos or playing games, and rates of childhood being very fat have doubled over the past 20 years," Robinson said. In the study, presented this week to the Pediatric Academic Societies' annual meeting in San Francisco, the researchers persuaded about 100 of the students to reduce their television viewing by one-quarter to one-third. Children watching fewer hours of television showed a significantly smaller increase in waist size and had less body fat than other students who continue their normal television viewing, even though neither group ate a special diet nor took part in any extra exercise. "One explanation for the weight loss could be the children unstuck to the television may simply have been moving around and burning off calories," Robinson said. "Another reason might be due to eating fewer meals in front of the television. Some studies have suggested that eating in front of the TV encourages people to eat more," Robinson added.

mmlu_train_60572 | In an ideal world,people would not test medicines on animals. Such experiments are stressful and sometimes painful for animals,and expensive and timeconsuming for people. Yet animal experimentation is still needed to help bridge vast gaps in medical knowledge. That is why there are some 50 to 100 million animals used in research around the world each year. Europe,on the whole,has the world's most restrictive laws on animal experiments. Even so,its scientists use some 12 million animals a year,most of them mice and rats,for medical research. Official statistics show that just 1.1 million animals are used in research in America each year. But that is misleading. The American authorities do not think mice and rats are worth counting and,as these are the most common laboratory animals,the true figure is much higher. Japan and China have even less comprehensive data than America. Now Europe is reforming the rules governing animal experiments by restricting the number of animals used in labs. Alternatives to animal testing,such as using human tissue or computer models,are now strongly recommended. In addition,sharing all research results freely should help to reduce the number of animals for scientific use. At present,scientists often share only the results of successful experiments. If their findings do not fit the hypothesis being tested,the work never sees the light of day. This practice means wasting time,money,and animals' lives in endlessly repeating the failed experiments. Animal experimentation has taught humanity a great deal and saved countless lives. It needs to continue,even if that means animals sometimes suffer. Europe's new measures should eventually both reduce the number of animals used in experiments and improve the way in which scientific research is conducted.

mmlu_train_53062 | Poor Oral Health Leads to Social and Emotional Problems A new report says nearly four-billion people have major tooth decay, or cavities. That number represents more than half of the world's population. Health officials are warning that failure to repair cavities can lead to social and emotional problems. Wagner Marcenes is with the Institute of Dentistry at Queen Mary, University of London. He led a team of researchers as part of the Global Burden of Disease 2010 study. About 500 researchers attempt to collect and examine studies about all major diseases. They used the information to estimate rates of the infection. The report says untreated tooth decay is the most common of all 291 major diseases and injuries. Professor Marcenes says cavities or holes in permanent teeth are also known as caries. "Caries is a chronic disease that shares the same risk factors as cancer, cardiovascular disease. What we're having now is an increase in disease from highly developed countries happening in sub-Saharan Africa and probably it will be in other areas of Africa, too." He says an increase in tooth decay in Africa could be a result of developing countries becoming more like Western nations. "It is likely to be related to a change in diet. Our industrialized diet leads to chronic disease, which includes caries. And that may be the main explanation." Western diets are rich in sugar, a leading cause of health problems in the mouth. Wagner Marcenes says oral health problems can have a major effect on a person's quality of life. First, cavities make eating difficult. Second, people may change what they eat. They may eat softer foods that are not hard to chew. However, softer foods are often fattier foods. But professor Marcenes says the biggest issue in tooth decay is both social and mental. He says the researchers found strong evidence that the mouth has a big influence on socialization. He says many people want to hide bad teeth. They smile less and communicate less. Wagner Marcenes is calling for an "urgent, organized, social response" to the widespread lack of oral health. He believes in a natural method to fight tooth decay by having a healthier diet. He is also calling for the development of new and less costly dental materials and treatments. Caries is a disease that _ . | [

Researches found that people become happier and experience less worry after they reach the age of fifty.In fact,they say by the age of eighty--five,people are happier with their life than they were when they were eighteen years old. The findings came from a survey of more than 340,000 adults in the United States.The Gallup Organization questioned them by telephone in 2008.At that time,the people were between the ages of eighteen and eighty--five.The searches asked questions about emotions like happiness,sadness and worry.They also asked about mental or emotional stress. Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study.His team found that levels of stress were highest among adults between the ages of twenty--two and twenty--five.The findings showed that stress levels dropped sharply after people reached their fifties.Happiness was highest among the youngest adults and those in their early seventies.The people least likely to report feeling negative emotions were those in their seventies and eighties. The study also showed that men and women had similar emotional patterns as they grew older.Hower,women at all ages reported more sadness,stress and worry than men.Researchers say they do not know why happiness increases as people get older.One theory is that,as people grow older,they grow more thankful for what they have and have better control of their emotion .They also spend less time thinking about bad experiences.

Now, a research group from University of London may have found the answer -- migrating birds fly in a "V" to save energy, according to a study published in the journal Nature. When a bird flaps its wings, it stirs the air around it and causes it to move indifferent directions. Scientist found in the study that the air creates an upward-moving wave at the tips of the wings, which means that if a bird flies around the wingtips of another bird, it can get a boost from the rising air and therefore use less energy to stay in the air. Apart form the "free ride" strategy, scientists were also surprised to observe that migrating birds timed their wing beats and adjusted their positions in a very precise way to maximize the lifting effect while avoiding areas where the air move downward. "They're able to sense what's going on from the bird in front, where this 'good air' is coming from and now how to position themselves perfectly in it," lead researcher Steven Portugal told BBC. In fact, the "V" formation has long thought to help birds fly more efficiently . A previous study showed that birds' heart rates went down when they were flying together in a "V" formation. Jet fighters were also found to be able reduce their energy use by up to 18% by staying near the wingtips of other jet fighters. Both of these findings led scientists to suspect that the "V" formation had an efficiency purpose, but until now they still lack proof. "For scientists, the new study provides an insight into an interesting natural phenomenon. But it could mean even more for aircraft companies -- helping them understand how they can _ that with their plane formations to save fuel, said Portugal."

Scientists have shown that eggs produce proteins with a function similar to that of powerful blood pressure-lowering drugs. The research, from the University of Alberta in Canada, showed that when eggs come in contact with stomach enzymes they produce a protein that acts in the same way as _ , but more work is needed to show the effects outside a lab and in the human body. Earlier this month, British researchers declared that, contrary to popular beliefs, it is healthy to go to work on an egg.They concluded that the type of cholesterol found in eggs has little effect on increasing heart disease risks. Researcher Professor Bruce Griffin, from the University of Surrey, said: "The wrong beliefs linking egg eating to high blood cholesterol and heart disease must be corrected.The amount of fat in our diet has an effect on blood cholesterol that is several times greater than the ly small amounts of cholesterol found in eggs.The UK public do not need to be limiting the number of eggs they eat.They can be encouraged to include them in a healthy diet as they are one of nature's most nutritious foods."

mmlu_train_46977 | If a diver surfaces too quickly, he may suffer the bends. Nitrogen dissolved in his blood is suddenly liberated by the reduction of pressure. The consequence, if the bubbles accumulate in a joint, is sharp pain and a bent body -- thus the name. If the bubbles form in his lungs or brain, the consequence can be death. Other air-breathing animals also suffer this decompression sickness if they surface too fast: whales, for example. And so, long ago, did ichthyosaurs . That these ancient sea-animals got the bends can be seen from their bones. If bubbles of nitrogen form inside the bone they can cut off its blood supply. This kills the cells in the bone, and consequently weakens it, sometimes to the point of collapse. Fossil bones that have caved in on themselves are thus a sign that the animal once had the bends. Bruce Rothschild of the University of Kansas knew all this when he began a suty of ichthyosaurs bones to find out how widespread the problem was in the past. What he particularly wanted to investigate was how ichthyosaurs adapted to the problem of decompession over the 150 milllion years. To this end, he and his colleagues traveled the world's natural-history museums, looking at hundreds of ichthyosaurs from the Trassic period and from the later Jurassic and Cretaceous periods. When he started, he assumed that signs of the bends would be rarer in younger fossils, reflecting their gradual evolution of measures to deal with decompression. Instead, he was astonished to discover the opposite. More than 15% of Jurassic and Cretaceous ichthyosaurs had suffered the bends before the died, but not a single Trassic specimen showed evidence of that sort of injury. If ichthyosaurs did evolve an anti-decompression means, they clearly did so quickly -- and, most strangly, they lost it afterwards. But that is not what Dr Rothchild thinks happened. He suspects it was evolution in other animals that caused the change. Whales that suffer the bends often do so because they have sufaced to escape a predator such as a large shark. One of the features of the Jurassia oceans was an abundance of large sharks and crocodiles, both of which were fond of ichthyosaurs lunches. Trassic oceans, by contrast, were mercifully shark-and crocodile-free. In the Trassic, then, ichthyosaurs were top of the food chain. In the Jurrasic and Cretaceous, they were prey as well as predator --and often had to make a speedy exit as a result. Rothchild might have concluded that ichthyosaurs _ . | [

People also realize that everyday stuff can be a source of energy too. For example, riding a bike, running or just walking, etc. We simply have to change our way of thinking if we want to change the world. So comes the idea of solar roadways. Are they the road of future? Why use roads just for driving and collecting tolls ? Why don't we use them for collecting energy? The US Department of Transportation recently awarded $100,000 to Solar Roadways to build the first ever Solar Road Panel. So how do these future roads work? The Solar Road Panels will contain embedded LEDs which "paint" the road lines from beneath to provide safer nighttime driving as well as to give drivers instant instructions such as detour ahead. The road will be able to sense wildlife on the road and can warn drivers to "slow down". There will also be embedded heating elements in the surface to prevent snow and ice buildup, providing safer winter driving. Replacing asphalt roads and parking lots with Solar Roadway Panels will be a major step toward stopping climate change. Fully electric vehicles will be able to recharge along the roadway and in parking lots, finally making electric cars practical for long trips. We just can't wait to see more of these roads all over the world in the near future. What is the text mainly about? | [

mmlu_train_49251 | Where is that noise coming from? Not sure? Try living with your eyes closed for a few years. Blind people are better at locating sounds than people who can see, a new study says, Without the benefits of vision the ears seem to work much better. Previous studies have shown that blind people are better than others at reaching out and touching the sources of sounds that are close by. Researchers from the University of Montreal wanted to see if blind people were also better at locating sounds that are far away. Twenty-three blind people participated in the study. All had been sightless for at least 20 years. Fourteen of them had lost their vision before age 11. The rest went blind after age 16. The experiment also included 10 people who could see but were wearing blindfolds. In one task, volunteers had to pick the direction of a sound coming from about 3 meters away. When the sound was in front of them or slightly off center in front, both groups performed equally well. When sounds came from the side or the back, however, the blind group performed much better than the blindfolded group. The participants who had been blind since childhood did slightly better than those who lost their sight later. Recognizing the locations of distant sounds can be a matter of life-or-death for blind people, say the researchers. Crossing the street, for instance, is much harder when you can't see the cars coming. Still, the researchers were surprised by how well the blind participants did, especially those who went blind after age 16. In another experiment, the scientists also found that parts of the brain that normally deal with visual information became active in locating sound in the people who were blind by age 11. These brain parts didn't show sound-location activity in the other group of blind people or in the sighted people. The scientists now want to learn more about the workings of brains of "late-onset" blind people. Which would be a proper title for the passage? | [

mmlu_train_31790 | Say you forgot about Valentine's Day, and it's too late to send someone some roses. Someday, you'll at least be able to send their odors . A Paris lab under the direction of David Edwards, Michigan Technological University alumnus, has created the oPhone, which will allow odors to be sent, by Bluetooth and smart phone attachments, to oPhones across the state, country or ocean, where the person who receive it can enjoy American Beauties or any other kinds of rose. It can be sent by email, tweet, or text. Edwards says the idea started with student designers in his class at Harvard, where he is a professor. Normally, he says, there's a clear end in sight, but with their project no one had a clue who was going to pay for the research or if there was even a market. With the early major buzz produced -- Wired Magazine, National Public Radio, and the British press -- Edwards is sure the market will come. "We create odor profiles ," says Blake Armstrong, director of business communications at Vapor Communications, an organization operating out of Le Lab in Paris. "We put that into the oChip that gives away that smell." Edwards said that the original four chips that will come with the first oPhones can be combined into thousands of different odors -- produced for 20 to 30 seconds. In fact, Le Lab is working with Cafe Coutume, the premier coffee shop in Paris, using oPhones to create nice experiences. "Imagine you are online and want to know what a particular brand of coffee would smell like," Edwards says. "Or, you are in an actual long line waiting to order. You just tap on the oPhone and get the experience." And there are other benefits. "Fragrance houses, of course, culinary, travel, but also healthcare. "A patient with brain damage had lost memory, and the oPhone can help bring that memory back. Improvements are already planned at the end of year--give phone to audience in 2015.

mmlu_train_30922 | When different species of birds flock together, their flight formations are determined by social dynamics both between and within species. New research from the Universities of Cambridge and Exeter reveals for the first time that, contrary to current models used to explain the movement of flocks, the differences between bird species and social relationships between individuals play a critical role in determining the dynamics of mixed-species flocks. The unified behaviour of bird flocks has puzzled scientists for hundreds of years. One naturalist from the turn of the century even suggested telepathy may be involved. There have since been more logical explanations, including mathematical models that show that repeated interactions among individuals following simple rules can _ coordinated group movements. However, these models usually rely on the assumption that individuals within groups are identical and interact independently, which may not reflect reality. Jolle Jolles, a PhD student at the University of Cambridge's Department of Zoology and author of the paper, said:"Spectacular collective behaviour can be found in a large range of animal species, and we now know that often these complex coordinated group movements may be the result of individuals following simple rules. However, rarely are the individual characteristics and social relationships within them taken into account. Our research highlights that these striking displays of group behaviour are much more complex." By analysing high-resolution photographs of mixed flocks of rooks and jackdaws (both from the corvid family), the researchers found that rather than individuals interacting in a consistent fashion throughout the flock, interactions depended on social dynamics between the different species as well as relationships within a species. The researchers discovered that birds prefer to fly close to members of their own species, and that the larger and more dominant rooks take the lead by flying near the front of flocks. Additionally, the lifelong, monogamous pair bonds that are characteristic of both species seem to be reflected in flight, as birds often fly particularly close to a single, same-species partner. Dr Alex Thornton, principal investigator of the Cambridge Jackdaw Project, now at the University of Exeter and author of the paper, said: "Together, our findings demonstrate that to understand the structure of groups -- such as bird flocks -- we need to consider the characteristics and relationships of the individuals within them."

"Your brain is a learning machine," says prefix = st1 /UniversityofCaliforniascientist Dr. Micha3el Merzenich. Given the right tools, we can train our brains to act like they did when we were younger. All that's required is the practice designed just for the purpose: a few exercises for the mind. Merzenich has developed a computer-based training method to speed up the process in which the brain deals with information (positence. com). Since much of the data we receive comes through speech, the Brain Fitness Program works with language and hearing to better speed and accuracy . Over the course of training, the program starts asking you to distinguish sounds (between "dog" and "dog", for example) at an increasingly faster speed. It's a bit like tennis instructor, says Merzenich, hitting balls at you faster and faster to keep you challenged . You may start out slow, but before long you're pretty quick. The biggest finding in brain research in the last ten years is that _ If you ask your brain to learn, it will learn. And it may even speed up while in the process.

He attended Washington High School but because of an unimportant detail he did not receive his diploma until 1962,long after he had received his Bachelor's degree in chemical engineering from Orgon State College in 1922. He had chosen to study his major because he could get a good job with it. He won the Nobel Prize for Chemistry in 1954 for his research into the nature of the chemical bond and its application to the explanation of the structure of complex substance. His interest in the "behavior" of molecules led him from physical chemistry to biological chemistry,especially of the human body. He began with proteins and their main parts,the amino acids ,which are called the"building blocks of life".In 1950,he constructed the first satisfactory model of a protein molecule,a discovery very important to the understanding of the living cell. During World WarII,Pauling was a member of the Research Board for National Security,for which he was awarded the Presidential Medal of Merit in 1948. However,the use of the atomic bomb near the end of the war turned Pauling in a new direction. Having long worked on the structure of molecules,he took an immediate interest in the deadly effects of nuclear fallout on human molecular structures. From then on,Pauling protested the production of the hydrogen bomb and supported the prevention of the spread of nuclear weapons.

mmlu_train_10984 | The NSA and GCHQ are tapping popular smart phone apps such as Angry Birds to gather the enormous amounts of very personal data those bits of software collect--including age, gender, marital status, income, education level and more, according to new reports from the New York Times and The Guardian. Citing secret documents provided by Edward Snowden, former NSA staff, the reports detail efforts to gain data collection from cell phone carriers and smart phones by tapping into "leaky" apps themselves. Both spy agencies showed a particular interest in Google Maps, which is accurate to within a few yards or better in some locations and would clearly pass along data about the area where phone owner is. "It effectively means that anyone using Google Maps on a smartphone is working in support of a GCHQ system," reads a secret 2008 report by the NSA's sister spy agency, according to the New York Times. More surprising is the wide range of apps that the agencies search for data, including innocent-seeming apps such as Angry Birds. One document in particular from GCHQ listed what information can be found from which apps, mentioning Android apps but suggesting the same data was available from the iPhone platform. Angry Birds maker Rovio Entertainment of Finland said it had no knowledge of any NSA or GCHQ programs for tapping into its users' data. "Rovio doesn't have any previous knowledge of this matter, and have not been aware of such activity in 3rd party advertising networks," said Saara Bergstrom. "Nor do we have any involvement with the organizations you mentioned." Mobile photos uploaded to social media sites like Facebook and Twitter appear to be a particularly rich source of information for the spy agencies as well. Metadata in the photos is briefly available. The NSA and GCHQ are able to tap into that metadata to collect a wealth of key data points about a person's life. "NSA does not profile everyday Americans as it carries out its foreign intelligence mission," the agency told the Times in response to questions about the program. During a Monday press conference, White House press secretary Jay Carney stressed that same position. "As the president said in his Jan. 17 speech, to the extent data is collected by the NSA, through whatever means, we are not interested in the communications of people who are not valid foreign intelligence targets and we are not after the information of ordinary Americans," he said.

mmlu_train_28186 | In the past two years, his wife, Merlie, and their seven children have said "goodbye" to him four times, most recently last month. Each time it has been unnecessary. Mr. Smart had a hip replacement in February at the Burnie hospital but was rushed back two months later with internal bleeding. "The doctors couldn't stop the bleeding," Mrs. Smart said. Medical staff told Mrs. Smart to contact her family, which includes children in Western Australia. "It took two days for them to get here. We had to hope he _ ." he did. "The doctors were there 24 hours a day and they stopped the bleeding. They brought him back," Mrs. Smart said. "I certainly believe in miracles because I've seen one happen, but it wouldn't have happened if the doctors didn't do what they did." It was the second time Mrs. Smart thought she was losing her husband of 54 years. Two years ago, Mr. Smart was admitted to the Launceston General Hospital after a heart attack and a few days later with intense pain caused by a hemorrhage . Again, the family was called to say goodbye---twice. "I was given a 50-50 chance of coming out of it, " Mr. Smart said. Going through the ordeal (,) then was trying on the family, who had prepared themselves for the worst. But to face the same situation only two years later was hard. The Smarts said the support they received at the Burnie hospital helped them through. And it seems the experience has also left an impression at the hospital. Mrs. Smart said when she rang recently and mentioned her husband's name, the reply was "ah the miracle man".

mmlu_train_80003 | Space travel is nothing new. The first spacecraft with a human was sent up into space in 1961. Since then, people have not only traveled to space, but also many of them have lived there in space stations for some time. The Soviet Union sent the first space station into space in 1971. This space station was called Salyut 1. Salyut 1 was designed as a place where people could live while they _ space and did experiments. The first group of astronauts lived there for 23 days. The Soviet Union went on to make seven more Salyut space stations. At about the same time, the United States built its own space station, called Skylab. Astronauts visited and often lived in these space stations for a short time. However, it wasn't until the late 1980s when The Soviet Union sent the Mir space station that people began to live in space for a longer time. Mir stayed in space from 1989 until 2001, when it was decided that the space station was too old and no longer safe to live in. Living in space stations seems to be fun, but astronauts face many problems. One of them is food. All the meals on space station are put together on Earth and sent there by space shuttle. Because the food has to last a long time (sometimes up to three months), a lot of it has to be stored in cans. The space station does not have a fridge, but it has a cool room to keep fruit and vegetables fresh. Astronauts also eat many other foods such as dried meat that do not need special care. Without the help of gravity, sitting down to eat can be tough. Astronauts sometimes have to fix themselves to the wall while eating. They also have to be very careful to that food does not float away. What can we infer from the passage? | [

mmlu_train_38786 | Fish contains lost of omega-3 fatty acids.These fatty acids have been shown to help prevent heart disease,lower blood pressure and reduce the risk of strokes.Researchers suggest that these benefits of eating fish far outweigh the risks of getting sick from contaminated fish. Ongoing studies find that omega-3 fatty acids work magic on the brain too.Pregnant? Go out and eat fish!

mmlu_train_28318 | Your cell phone holds secrets about you. Besides the names and numbers that you've programmed into it, traces of your DNA remain on it, according to a new study. DNA is genetic material that appears in every cell. Like your fingerprint, your DNA is unique to you --- unless you have an identical twin. Scientists today usually analyze DNA in blood,saliva , or hair left behind at the scene of a crime. The results often help detectives identify criminals and their victims. Meghan J. McFadden, a biologist at McMaster University in Hamilton, Ontario, heard about a crime in which the suspect bled onto a cell phone and later dropped the device. This made her wonder whether traces of DNA remained on cell phones --- even when no blood was involved. To find out, she and a colleague collectedflip-style phones from 10 volunteers. They collected invisible traces of the users from two parts of the phone: the outside, where the user holds it, and the speaker, which is placed at the user's ear. The scientists scrubbed(meaning "cleaned") the phones using a liquid mixture made mostly of alcohol. The aim of washing was to remove all detectable traces of DNA. The owners got their phones back for another week. Then the researchers collected the phones and repeated collecting traces on each phone once more. They discovered DNA that belonged to the phone's owner on each of the phones. Surprisingly, DNA showed up even in swabs that were taken immediately after the phones were cleaned. That suggests that washing won't remove all traces of evidence from a criminal's cell phone. So cell phones can now be added to the list of clues that can help a crime-scene investigation. Which of the following is NOT mentioned in the passage? | [
"The reason for collecting the phones from volunteers.",
"The technique of collecting DNA on the phones.",
"The method of removing traces of DNA on the phones.",
