mmlu_train_55285 | SAN FRANCISCO--A phone app in San Francisco gives information about open parking spots.City officials in San Francisco introduced the app to try to reduce traffic jams in the city, but some say it raises safety concerns. In this city, drivers searching for parking spots lead to 30 percent of all downtown jams, city officials think.Now San Francisco has found a solution -- a phone app for spot-seekers that shows information about areas with available spaces.The system, introduced last month, relies on wireless sensors fixed in streets and city garages that can tell within seconds if a spot has opened up. But the system could come with serious consequences.Some people say that drivers searching for parking could end up focusing on their phones, not the road."It could be really distracting ," said Daniel Simons, a professor of psychology at the University of Illinois. City officials admitted the hidden problem.They are urging drivers to pull over before they use the city's iPhone app, or to do so before they leave home. Nathaniel Ford, executive director of the San Francisco Municipal Transportation Agency, said safety could actually improve if drivers quickly found a spot instead of circling and getting frustrated. San Francisco has put sensors into 7,000 parking spots and 12,250 spots in city garages.If spaces in an area open up, the sensors communicate wirelessly with computers that in turn make the information available to app users within a minute, said Mr. Ford, of the transportation agency.On the app, a map shows which blocks have lots of places(blue)and which are full(red). More than 12,000 people have downloaded San Francisco's app, which is available now only for the iPhone. What's the main idea of the passage? | [

mmlu_train_47335 | Canadian scientists have found that the more emotional or mental challenges a person faces in a day, the less determined they become to work out physically. However, the findings should not stop us from keeping fit. Experts believe that willpower is like a muscle, and needs to be exercised to help one avoid the temptation spending a night on the couch instead. Kathleen Martin-Ginis, a professor of kinesiology-the science of movement--who led the study, says everyone has a limited amount of willpower, and that it will be reduced by stress. Miss Martin-Ginis, of Canada's McMaster University, explains," Cognitive tasks, as well as tasks such as regulating one's emotions, can reduce one's capacity to force oneself to exercise. " Her team of scientists performed a so-called "Stroop" test on volunteers to reach their conclusions. The experiment involved showing participants words associated with color1s but printed in different color1s-for example, the word "blue" written in red ink Participants were divided into two groups. One group was asked to name the color1 of the ink, instead to say the printed word, while the other wasn't Martin-Girus says, "After we used this cognitive task to use up their self-regulatory capacity, the participants didn't exercise as hard as those who had not performed the task " The more people concentrated on the cognitive task, the more likely they were to skip exercise sessions over the next eight week You only have so much willpower. However, there are ways to strengthen willpower. The study found the listening to music before going to the gym can help, as well as making a commitment to work out with friends. It also concluded that willpower can be stretched by constant cake, or forcing oneself to study an extra hour each night Martin- Ginis adds," There are strategies people can use to help revitalize themselves after they've used up their self-regulation Willpower is like a muscle: it needs to be used to stay strong.

mmlu_train_63940 | 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."

mmlu_train_18963 | We've reached a strange--some would say unusual--point. While fighting world hunger continues to be the matter of vital importance according to a recent report from the World Health Organization (WHO), more people now die from being overweight, or say, from being extremely fat, than from being underweight. It's the good life that's more likely to kill us these days. Worse, nearly l8 million children under the age of five around the world are estimated to be overweight. What's going on? We really don't have many excuses for our weight problems. The dangers of the problem have been drilled into us by public-health campaigns since 2001 and the message is getting through--up to a point. In the 1970s, Finland, for example, had the highest rate of heart disease in the world and being overweight was its main cause. Not any more. A public-health campaign has greatly reduced the number of heart disease deaths by 80 per cent over the past three decades. Maybe that explains why the percentage of people in Finland taking diet pills doubled between 2001 and 2005, and doctors even offer surgery of removing fat inside and change the shape of the body. That has become a sort of fashion. No wonder it ranks as the world's most body-conscious country. We know what we should be doing to lose weight--but actually doing it is another matter. By far the most popular excuse is not taking enough exercise. More than half of us admit we lack willpower. Others blame good food. They say: it's just too inviting and it makes them overeat. Still others lay the blame on the Americans, complaining that pounds have piled on thanks to eating too much American-style fast food. Some also blame their parents--their genes. But unfortunately, the parents are wronged because they're normal in shape, or rather slim. It's a similar story around the world, although people are relatively unlikely to have tried to lose weight. Parents are eager to see their kids shape up. Do as I say--not as I do. Why does the author think that people have no excuse for being overweight? | [

mmlu_train_29185 | Imagine your body is like the house you live in. Every day, your family creates rubbish. The rubbish builds up until it is put out for the weekly garbage collection. Now, say you put three bags of garbage out, but because one of the collectors was away sick, only two bags are collected. You take the leftover bag inside to be put out again next week. The following week you put on another three bags, plus the leftover bag from last week. But again, only two bags are collected. Imagine this cycle is repeated over the following weeks. This is a simple description of what happens to your body when your kidneys don't work efficiently. Your body is not thoroughly emptied of waste products. Other areas of the body such as blood pressure and red blood cell production are affected and the _ process that may lead to kidney failure begins. It's not uncommon for people to lose up to 90% of their kidney function before developing any symptoms. There may be no warning signs. This makes early detection difficult. Kidney's main job is to remove toxins and unwanted water from our blood. Every day our kidneys clean an average of 200 litres of blood. Kidney failure may be a gradual and silent process, going unnoticed because there is no apparent pain. Research shows that more than 25% of the patients requiring dialysis do not see a kidney specialist before they have to do so. Some risk factors for kidney disease such as age and genetic make up are out of our control; however, some changes in lifestyle may help prevent kidney damage.Two major risk factors for kidney disease, diabetes and high blood pressure, have been on the rise over the last few decades.Both conditions are chiefly affected by being overweight and not getting enough exercises, which are the potential risk factors for the kidney disease. Which of the following helps prevent kidney damage most effectively? | [

mmlu_train_10401 | The largest known outbreak of the lethal Ebola virus in West Africa is prompting authorities as far away as Asia to take preventive measures, although scientists say a global spread of the disease is unlikely. At South Korea's Incheon International airport, a major hub for air travel in Asia, quarantine inspections of arriving passengers are being enhanced. Authorities say all passengers are being recorded by an infrared camera to detect fevers because Ebola is becoming a big concern. The incubation period of the Ebola virus is between two and 21 days, during which time an infected person might not show any signs of infection. In Hong Kong, the Center for Health Protection says public hospitals will begin to report and test all those who developed fever who, within the past 21 days, traveled to the three affected African countries. Singapore's health ministry is urging the public there "not to be alarmed." It has issued a statement deeming Ebola to pose "a low public health risk to Singapore," in part because "there is low travel connectivity to West Africa where the current outbreak remains limited to." Some airlines have suspended flights into the affected region. But health authorities say there is little risk of passengers contracting the virus on a flight from an infected person.Dr. Day, a tropical medicine researcher, explains Ebola is only spread through direct contact with blood, saliva and other bodily fluids. Since March, there have been more than 1,200 confirmed Ebola cases in West Africa. This is believed to be a new strain of the virus and nearly 700 of those infected in this worst-known outbreak have died.There is no known cure for Ebola. It was first recognized in Zaire (now the Democratic Republic of Congo) in 1976. There is no approved vaccine, but at least four are under development. Why does Singapore's health ministry urge the public not to be alarmed? | [

mmlu_train_13717 | With only about 1, 000 pandas left in the world, China is desperately trying to clone the animal and save the endangered species . That's a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called "Noah's Ark". Noah's Ark is aimed at collecting eggs, embryos , semen and DNA of endangered animals and storing them in liquid nitrogen . If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M's College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future. It is estimated that as many as 2,000 species of mammals, birds reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years. This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal. The entire procedure could take from three to five years to complete. "The nuclear transfer of one species to another is not easy, and the lack of available(capable of being used) panda eggs could be a major problem," Kraemer believes. "They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it's difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort," adds Kraemer, who is one of the leaders of the Project at Texas A& M, the first-ever attempt at cloning a dog. "They are trying to do something that's never been done, and this is very similar to our work in Noah's Ark. We're both trying to save animals that face extinction. I certainly appreciate their effort and there's a lot we can learn from what they are attempting to do. It's a research that is very much needed. " The best title for the passage may be _ . | [

As digital media is important to _ . the project is already providing chances for some of the many small new local companies working at the new technologies. Brian Gambles, the LoB project director, says it is about giving people the right tools for learning, "The aim is to mix the physical with the digital. Providing 24-hour services which can be used through many different ways. It is important to enable us to reach more people, more effectively." The digital library will, he says, be as important as the physical one, allowing the distant use of the services, making sure that it is never closed to the public. Even before the LoB is complete, the public has been able to go online to visit the Virtual LoB, designed by Baden, the Birmingham virtual worlds specialists. Not only have the public been able to learn about LoB, but the virtual one has also enabled those working on the LoB to understand the building and how it will work before it even opens.

mmlu_train_53592 | Crystal Ear One day a friend asked my wife Jill if I wanted a hearing aid. "He certainly does,"replied Jill. After hearing about a remarkable new product, Jill finally got up the nerve to ask me if I'd ever thought about getting a hearing aid. "No way,"I said. "It would make me look 20 years older.""No, no"she replied. "This is entirely different. It's Crystal Ear!" Jill was right. Crystal Ear is different ---- not the old-styled body worn or over-the-ear aid, but an advanced personal sound system so small it's like contacts for your ears. And Crystal Ear is super-sensitive and powerful, too. You will hear sounds your ears have been missing for years. Crystal Ear will make speech louder, and the sound is pure and natural. I couldn't believe how tiny it is. It is smaller than the tip of my little finger and it's almost invisible when worn. There are no wires, no behind-the-ear device. Put it in your ear and its-ready-to-wear mold fits comfortable. Since it's not too loud or too light, you may even forget that you're wearing it! Use it at work or at play. And if your hearing problem is worse in certain situation, use Crystal Ear only when you need it. Hearing loss, which is typically prior to teenage years, progresses throughout one's lifetime. Although hearing loss is now the world's number-one health problem, nearly 90 percent of people suffering hearing loss choose to leave the problem untreated. For many millions, treating hearing loss in a conventional way can involve numerous office visits, expensive testing and adjustments to fit your ear. Thanks to Crystal Ear, the "sound solution"is now convenient. Almost 90 percent of people with mild hearing loss, and millions more with just a little hearing dropoff, can be dramatically helped with Crystal Ear. Moreover, its superior design is energy-efficient, so batteries can last months. Crystal Ear is now available to help these people treat their hearing loss with a small hearing amplifier .

Sound has a waste product, too, in the form of noise. Noise has been called unwanted sound. Noise is growing and it may get much worse before it gets any better. Scientists, for several years, have been studying how noise affects people and animals and are alarmed by what they have learned. Peace and quiet are becoming harder to find. Noise pollution is no joke. It is a threat that should be looked at carefully. Sound is measured in units called decibels . At a level of 140 decibels people feel pain in their ears. Trucks, buses, motorcycles, airplanes, boats, and factories all make noise. This noise bothers not only our ears, but our minds and bodies as well. There is a saying about "it is so noisy that you can't hear yourself think". Doctors who study noise believe that we must be able to hear ourselves think most of the time. If we don't, we may have headaches, other aches and pains, or even mental problems. Noise adds even more tension to a society which already faces too much stress. The sense of hearing _ . | [

mmlu_train_84730 | What should you take in with you when you take an exam? Pen, pencil, eraser, ruler..., and don't forget a bottle of water! According to a study at the British Psychological ( ) Society Annual Conference held in London, students who bring water into exams may improve their grades by up to 10 percent. Scientists at the University of East London and the University of Westminster, UK, did a study on 447 students. The students were studying for different degrees at the University of East London. Only 25 percent of them entered the exam hall with something to drink. Scientists then compared their exam results with their normal schoolwork grades. They found that all those who had brought drinks with them got better grades by between 2 and 10 percent. It is unclear why drinking water improves exam results. But scientists say having enough water in our bodies and not feeling thirsty could have a helpful effect on our brains. Drinking water may also cut down on anxiety ( ), which has a bad effect on exam performances, according to Chris Pawson, PhD, of the University of East London. "Whatever the explanation, it is clear that students should try hard to stay hydrated with water during exams," he said. So next time, when you are going to have a big exam, try bringing a bottle of water with you.Who knows - it may help you pass the exam! Where can you probably read the article? | [

mmlu_train_14167 | Millions of people die of hunger in southern Africa every year, but when Zambia was offered thousands of tons of free maize by the US, the government politely said no. "We don't know whether the food is safe," said Zambia's commerce, Trade and Industry Minister Dipak Patel. His worries are shared by countries around the world that are in two minds about America's genetically modified(GM,)crops.Just last week, EU member nations were discussing whether or not to import GM sweet corn from the US. Ever since people started farming, they have tried to crossbreed plants to make them stronger or better tasting. At one time, only related plants could be crossed with each other. But when GM techniques were developed in the 1970s, scientists were able to put a single gene from a living creature into an unrelated creature. This means they can make crops more productive and resistant to disease by adding genes from other species.They can also create food with special characteristics, such as "golden rice", which is enriched with vitamin A. But many people believe GM foods are a health risk. At the moment, the official argument is that GM foods "are not likely to present risks for human health". But there are still many questions to be answered as the foods are produced in different ways. Some experts believe the genetic material added to plants can transfer to humans and give damage to our bodies. Further harm could be caused by the genes from GM plants crossbreeding with naturally produced crops. People in China are also getting worried about GM foods. More than 70 percent of the country's soybean oil is produced from imported GM soybeans. Meanwhile, an investigation last November found that 12 of 60 famous foods sold across the country were GM products. The government has begun to introduce a marking system for GM goods so that people can choose whether or not to eat them. What's the author's attitude towards GM foods? | [

MySpace is a place that allows you to broadcast your own stories and personal information to as many people as you like. Started two years ago, it is a big source of information for and about American kids. Teenagers and their parents feel very differently about it. Teens are rushing to join the site, not sharing their parents' worries. It signals yet another generation gap in the digital era. For teenagers, it is reliable network to keep in touch with their friends. They will often list their surnames, birthdays, afterschool jobs, school clubs, hobbies and other personal information. "MySpace is an easy way to reach just about everyone. I don't have all the phone numbers of all my acquaintances . But if I want to get in touch with one of them, I could just leave them a message on MySpace." said Abby Van Wassen. She is a sixteen year old student at Woodland Hills High of Pittsburgh, Pennsylvania. Parents on the other hand are seriously concerned about the security problems of MySpace. "Every time we hold a parents meeting, the first question is always about MySpace," said Kent Gates, who travels the country doing Internet safety seminars .The National Center for Missing and Exploited Children has received at least 288 MySpace related complaints, according to Mary Beth Buchanan, a lawyer in Pittsburgh.

Five minutes later, he's on the field with his friends, running after a soccer ball. Rick has asthma , but he knows how to control it. Asthma is a lung disease. A person with asthma may cough or suffer from shortness of breath. Asthma can begin at any age. Childhood asthma, often beginning when a child is younger than 10 years old, is one of the most common childhood diseases. Doctors report that the number of young people with asthma is increasing. It is the number one cause of absence from school. If parents have asthma, their children are more likely to develop the disease. Children in homes where an adult smokes are more at risk. It is important to find out the _ for asthma. As we know, dust, pollen, or animals often make people suffer from asthma. Once a child learns the triggers, he can help prevent future attacks. About half of all children outgrow asthma and then asthma attacks stop when they are teenagers. However, many people live with the disease into adulthood. Children often take control drugs once or twice a day to help prevent asthma attacks, if a child begins to have an asthma attack, a quick-relief drug is also necessary. This is often an inhaler. School-aged children usually carry their inhalers with them. This medication works quickly and children begin to breathe more easily in a few minutes. If a child has a serious asthma attack, he may need full-time care at a hospital or a doctor's office. The story of Rick Garcia is used to _ . | [

mmlu_train_6275 | Today just as technology changed the face of industry, farmers have undergone an "agricultural revolution". On the farm of today, machines provide all the power. One of the most important benefits will be the farm computer. A few forward-looking farmers are already using computers to help them run their farms more efficiently. The computers help them keep more accurate records so they can make better decisions on what crops to plant, how much livestock to buy, when to sell their products, and how much profit they can expect. Many computer companies have been developing special computer programs just for farmers. Programs are being written for hog producers, grain farmers, potato farmers, and dairy farmers. In the future, farmers will be able to purchase computer programs made to their needs. Because of the growing importance of computers on the farm, students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses. There can be no doubt that farmers will rely on computers even more in the future. While the old-time farm depended on horse power, and modern farms depend on machine power, farms of the future will depend on computer power. Another technological advance which is still in the experimental stage is the robot, a real "mechanized hired hand" that will be able to move and, in some ways, think like a human being. Unlike farmers of the present, farmers of the future will find that many day-to-day tasks will be done for them. Scientists are now developing robots that will be able to shear sheep, drive tractors, and harvest fruit. Even complex jobs will be done by robots. For example, in order to milk their cows, farmers must first drive them into the special barn , then connect them to the milking machines, watch the machines, and disconnect them when they are finished. In the future, this will all be done by robots. In addition, when the milking is completed, the robots will automatically check to make sure that the milk is pure. The complete mobilization of the farm is far in the future, but engineers expect that some robots will be used before long. Which of the following statements is true? | [

Your home printer exactly shoots drops of ink onto a flat piece of paper, creating the robot's 2-D image. "Printing" 3-D objects is different. Take the purple robot. First select a file of the 3-D printer. Immediately, the printer begins making noise, and a nozzle releases plastic material in thin layers. In two or three hours, a 3-D purple robot is standing before you. 3-D printing has developed to the point where printers can now create high-quality objects using a variety of materials, including metals. That means 3-D printers can now make final products that meet high industrial standards. 3-D printers are already being used to make parts for racecars and jets as well as man-made limbs and hearing aids. So far, few homes have 3-D printers. That's because 3-D printing is not only new to most people but also quite expensive. To bring 3-D printing to the masses, some retail stores plan to offer the service. For example, the Staples chain of office supply stores has announced that it will offer 3-D printing in Europe beginning in 2013. Customers will be able to submit their own 3-D designs to Staples website for printing. After the job is done, they'll pick up their item at a nearby Staples store or have it mailed to their homes. This service is sure to encourage many more people to try out 3-D printing. What will customers need in order to submit their designs to Staples? | [

mmlu_train_12780 | Drink drivers could be prohibited from driving under the influence if new technology from Nissan is introduced. The Japanese car maker has developed a new odor detection system designed to prevent drivers from operating a car if they are over the legal limit. The system works by using a series of sensors to detect the level of alcohol the driver has consumed. A high-sensitivity alcohol odor sensor is built into the gear stick , which is able to detect the presence of the driver's palm as he or she attempts to start driving. If the alcohol level detected is above a pre-determined limit, the system automatically locks the transmission , immobilizing the car. A voice alert is also issued via the car navigation system telling the driver that he or she is over the limit. Extra sensors are also placed in the driver and passenger seats and a warning is issued if these sensors detect the presence of alcohol in the air inside the vehicle cabin. While still in the developmental stage the concept of drink driving detectors being built into cars has generally been welcomed by many drivers. Nissan said the technology is part of a project aimed at halving the number of fatalities and serious injuries in Nissan cars by 2015 compared to 2005 levels. The detection system works _ . | [

FACT 1: Talk to Me Like humans, every dolphin has its own "name". The name is a special whistle . Each dolphin chooses a specific whistle for itself, usually by its first birthday. Actually, scientists think dolphins, like people, "talk" to each other about a lot of things, such as their age, their feelings, or finding food. And, like humans dolphins use a system of sounds and body language to communicate. But understanding their conversations is not easy for humans. No one "speaks dolphin" yet, but some scientists are trying to learn. FACT 2: Let's Play Dolphins are also social animals. They live in groups called pods, and they often join others from different pods to play games and have fun ---just like people. In fact, playing together is something only intelligent animals do. FACT 3: Fishermen's Helpers Dolphins and humans are similar in another way: both make plans to get something they want. In the sea of southern Brazil, for example, dolphins use a interesting strategy to get food. When fish are near a boat, dolphins signal to the fishermen to put their nets in the water.

A major football event will happen in the South American country later this month, but with teams of robots playing the game, which is known as soccer in the United States. The robot teams are guided by teams of humans from around the world. The event is known as RoboCup. Technology students at the University of Pennsylvania are trying for their fourth victory at the competition, which is held this year in the coastal city Joao Pessoa. The students have won the last three RoboCup competitions. Watching robots play football is similar to watching children play the game. The kicks are not good, there's a lot of falling down, and people are there to guide and support the team members. Jian Qiao Li is one of the leaders of the University of Pennsylvania team. He says one goal he has for the robot team is to make sure the machines can find the goal and the ball. He also wants the robots to be able to know where they are on the playing field. And he wants the team to be able to better control the walking and kicking abilities of the robots. Qin He is another leader of the robot team. She says the abilities of the robots increase every year. Ms. He says the US team is meeting its goals. The robots know the differences between the colors green and red, and they can decide where to go and where the ball is on the playing field. She says if there are three robot players on the field at the same time, they will communicate with each other to decide the different responsibilities for each robot. U. S. Team member Christopher Akatusuka hopes for another victory in Brazil. The team has won the RoboCup the past three years in the Netherlands, Mexico and Turkey.

The North Star is the brightest star in the constellation known as the Little Dipper. It is so-called because of the special position. If you were to stay up all night looking at the stars, you'd slowly see them move around a point in the sky known as the North Celestial Pole. You would notice, however, that one star remains still. This is the North Star, so named for its location almost directly in line with the North Celestial Pole. Due to its position in the sky, at one time sailors used the North Star as a navigational tool. By measuring the angle between the northern horizon and the North Star, a navigator could accurately determine the ship's latitude.[:ZXXK] But latitude, or the imaginary lines stretching across the globe parallel to the equator, was not enough to plot a ship's location. Knowing latitude only allowed navigators to locate themselves on a particular latitude line at a particular distance from the equator.

Many bloggers are teenagers who log onto websites to discuss anything in their lives. Many of today's teenagers are not afraid to openly discuss everything in their lives. Teenagers complain about parents and homework. They share diaries, post songs from the latest bands and show pictures of theirs. They write their own poems, say something about their girlfriends or boyfriends and complain to each other or offer support. But mostly they just write down what they do every day. However, many parents are worried about these young bloggers. Parents see the kids talking about how they got drunk last weekend and how they don't like studying. They are using language that is surprising to their parents. Besides hearing from their friends, teen bloggers also get messages from strangers.

Poor sleep is associated with a range of cardiovascular problems, including high blood pressure, heart attack, and heart failure. Both men and women are at increased risk for these conditions. But we continue to learn that when it comes to health problems associated with sleep, the particular risks to men and women are not always the same. A new study suggests that for women who already have heart disease, poor sleep may be particularly dangerous to their heart health. Research indicates that poor-quality sleep--and waking too early in particular--is associated with increased inflammation among women with heart disease. There was no similar association found for men, suggesting that women with heart disease and sleep problems may be at particular risk for inflammation that can be damaging to the heart. Researchers at the University of California, San Francisco investigated the relationship between sleep quality and inflammation linked to coronary heart disease. They also sought information about how an association between sleep and inflammation might differ between men and women. Their investigation included 980 men and women at first, and 626 completed the 5-year study. All of those included were suffering for coronary heart disease. The average age of men in the study was 66. Women were slightly younger, with an average age of 64. Researchers measured sleep quality by asking participants to rate their sleep over the previous month. They also asked for reports of some of the most common sleep problems, including difficulty falling asleep, difficulty staying asleep, waking frequently throughout the night, and waking too early in the morning. After 5 years, researchers repeated tests for inflammation and once again sought reports on sleep quality and sleep problems. When they analyzed data for both men and women together, researchers found no links between inflammations and sleep quality. However, when they analyzed data taking gender into account, researchers found a relationship between inflammation and sleep existed for women, but not for men.

Two reports show that surfing the Internet and sending personal information to people you do not know could be a problem. Most sites give users their own webspace where they can write their diaries or post their pictures. The sites encourage users to get their friends to look at their work and to comment on what are posted on the sites. Teachers are worried that some children are posting their personal information on websites. This could put them at risk from those who plan to do harm to young people. Teachers are also worried some users think it is OK to use the websites in a way that could get others into trouble. In a school in Illinois in the US where some popular sites are used wildly, the school would punish students who posted pictures or information about smoking , drinking and other illegal activities on the websites. The school is now going to encourage its 3,200 students to obey a new rule. The warning is clear. That is, be careful when posting information about yourself such as your age, sex, address and interests on a website that anyone can see. Another warning about the Internet comes from a report. It shows searchers are leading users to websites that show them spam and other dangerous downloads.The words " free _ " were found to be the most dangerous words that people search for. It is well-known that visiting sites offering free MP3s leave users at serious risk. Spyware should be installed on their computers. So, happy surfing ,but remember not to get caught in the Net!

Tim Bajarin, president of a high-tech research and consulting company, said "If you actually look at a tech leader, they're really happy if they have one hit in their life.Steve Jobs has the Apple II, the Mac, the iPod, the iPhone, the iPad and Pixar." Steve Jobs was a college dropout.He was adopted by a machinist and his wife, an accountant.They supported his early interest in electronics. He and his friend Steve Wozniak started Apple Computer--now just called Apple--in nineteen seventy-six.They stayed at the company until nineteen eighty-five.That year, Steve Wozniak returned to college and Steve Jobs left in a dispute with the chief executive. Mr.Jobs then formed his own company, called NeXT Computer.He rejoined Apple in nineteen ninety-seven after it bought NeXT.He helped remake Apple from a business that was in bad shape then to one of the most valuable companies in the world today. Steve Wozniak, speaking on CNN, remembered his longtime friend as a "great visionary and leader'' and a "marketing genius ". President Obama said in a statement: "By building one of the planet's most successful companies from his garage, _ .By making computers personal and putting the Internet in our pockets, he made the information revolution not only accessible, but intuitive and fun." David Carroll is a professor at Parsons School of Design in New York City.He says Steve Jobs not only revolutionized technology, he also revolutionized American business. "The fact that he was able to redesign American commerce top to bottom and across is really stunning .He probably will be considered an industrial giant on the scale of Thomas Edison and Henry Ford, so one of the great[s] of all time." David Carroll said. Steve Jobs stepped down as Apple's chief executive in August because of his health.He died a day after the company released a new iPhone version that met with limited excitement.Apple's new chief, Tim Cook, will also have to deal with the new Kindle Fire tablet computer from Amazon.com.It costs less than half as much as an iPad but also does less.

mmlu_train_37896 | DNA left at a crime scene could be used in the future to build up a picture of an offender's face, it was revealed tonight. A first step towards genetic _ has been taken by researchers in the US who link specific DNA markers with face shape. To identify the genes, they focused on known mutations that cause changes of the face and head. Normal versions of these genes were found to influence individual features. For instance, one gene affected the lips, another the shape and configuration of bones around the eyes, and a third the appearance of the mid-face and skull. In total, 20 genes had "significant effects" on facial appearance. Lead scientist Professor Mark Shriver, from Pennsylvania State University, said: "We use DNA to match to an individual or identify an individual, but you can get so much more from DNA. Currently we can't go from DNA to a face, or from a face to DNA, but it should be possible." The implications are far reaching, raising the possibility of creating a data bank of facial types based on genetic markers. DNA from a crime scene could then be used to produce a rough image of the face of an offender or victim. Such genetic mugshots may be more reliable than computer-generated "e-fits" based on witnesses' recollections. Other uses of the technique might include proving the identity of fathers in paternity cases, or visualising our remote ancestors from fossil DNA. The scientists wrote in the online journal Public Library of Science Genetics: "Such predictive modelling could be forensically useful; for example, DNA left at crime scenes could be tested and faces predicted in order to help to narrow the pool of potential suspects. Further, our methods could be used to predict the facial features of descendants, deceased ancestors, and even extinct human species. In addition, these methods could prove to be useful diagnostic tools." The team developed a model which first established a range of physical face shapes from people of mixed West African and European ancestry from the US, Brazil and Cape Verde. Measurements were taken of thousands of point co-ordinates on grids placed over 3D images of the faces. Statistical methods were then used to determine the relationship between facial differences and the effects of gender, ethnic ancestry and individual gene variants. According to Professor Mark Shriver, we know _ . | [

mmlu_train_70483 | The keys to reaching or staying at a healthy weight are regular exercise and good eating habits. Teens should get 60 minutes or more of physical activity a day. Note the word "activity". As long as you're getting your body moving, it doesn't have to mean doing difficult exercise or going to the sports hall every day. All that matters is that each week you get the right balance of activity, including aerobics , strength building, and flexibility exercise. Make exercise a habit by arranging some time every day. On days when you have soccer practice or an aerobics class, you may have no trouble exercising for an hour or more. But most of us are busy, and 60 minutes a day for exercise seems like a lot of time. The good news is that it's OK to divide it into shorter exercise breaks throughout the day. Just as you might have a healthy snack to stop yourself from getting hungry, exercise snacks can keep energy levels high. So get up 15 minutes early and do some stretching activity. Walk fast or run slowly for 15 minutes after lunch. Do the same thing after school -- or walk or bike home. Add to that taking the stairs, PE class, and walking between classes during the day, and you've probably reached your 60 minutes. Here are five simple ways to make an exercise lifestyle change: The writer thinks many people probably misunderstand the word"activity" to be " _ ". | [

Some parts of most modern buildings--theaters and offices as well as classrooms-are more than sufficiently heated by people and lights and sometimes must be air conditioned even in winter.The technique of saving heat and redistributing it is called "heat recovery".A few modem buildings recover heat,but the University's system is the first to recover heat from buildings and reuse it in others. Along the way, Pitt has learned a great deal about some of its producers.The harder a student studies the more heat his body gives off.Male students send out more heat than female students and the larger a student,the more heat he produces.It is tempting to conclude that _ for the Johnstown campus would be a hard-working overweight male genius .

mmlu_train_37626 | Farming is moving indoors, where the sun never shines, where rainfall is irrelevant and where the climate is always right. The perfect crop field could be inside a windowless building with controlled light, temperature,humidity,air quality and nutrition. It could be in a New York high- rise or a complex in the Saudi desert. It may be an answer to the world's food problems. The world already is having trouble feeding itself. Half the people on Earth live in cities, and nearly half of those - about 3 billion - are hungry or ill-fed. Food prices, currently increasing, are badly affected by dryness, floods and the cost of energy required to plant, harvest and transport it. And prices will only get more unstable. Climate change makes long-term crop planning uncertain. Farmers in many parts of the world already are using water available to the last drop. And the world is getting more crowded: by mid-century, the global population will grow from 6.8 billion to 9 billion. To feed so many people may require expanding farmland at the expense of forests and wilderness, or finding ways to greatly increase crop output. Gertjan Meeuws and three other Dutch bioengineers grow vegetables and house plants in closed and regulated environments. In their research station, water flows into the pans when needed, and the temperature is kept constant. Lights go on and off, creating "day" and "night", but according to the rhythm of the plant. Meeuws says a building of 100 square meters and layers of plants could provide a daily diet of 200 grams of fresh fruit and vegetables for the entire population of Ken Bosch, about 140,000 people. Their idea isn't to grow foods that require much space, like corn or potatoes. Sunlight is not only unnecessary but can be harmful. Plants need only specific wavelengths of light to grow. Their growth rate is three times faster than under greenhouse conditions. They use about 90 percent less water than outdoor agriculture. And city farming means producing food near the consumer, so there's on need to transport it long distances. What is the purpose of the text ? | [

mmlu_train_31954 | Accidents and illness are unhappy things to talk about, but no one can expect to live a lifetime without having some kind of accident or becoming ill. Some accidents and illnesses are serious and may result in long periods of invalidism. The newspapers contain spectacular accounts of accidents in the street and highways and public places, but nearly as many accidents occur around the home. Somebody trips on a rug. Somebody falls off a stepladder. Somebody is careless in cooking dinner, and is burned. Accidents incurred in the playing of sports and swimming also accounts for a large number of injuries, big and little. Despite constant campaigns to reduce the number of accidents, there are still approximately 100,000 accidental deaths and nearly 9,000,000 nonfatal injuries in the United States each year. It has been estimated that around 3,000,000 people are constantly ill in the United States throughout the year and that over half the illness is caused by respiratory diseases, chiefly colds and influenza. The pain and suffering caused by accidents and illness tell only half the story. Loss of time from school and work and medical and hospital expenses often make the pain seem worse. Money spent in this country for doctors, services, hospitalization, nursing care, drugs, medicines, Xrays, and special treatments, amounts to a huge annual sum. Added to this expense is another much larger amount that is lost to wage earners throughout the nation by reason of their loss of wages or income while sick or otherwise disabled. Accident and health insurance is a form of insurance devised to protect against these economic losses. It protects the earning of wage earners and finishes financial aid to the family of the breadwinner by the payment of his doctor and hospital bills. Today, business and professional men, farmers, industrial workers, clerks and those engaged in various occupations, whose earning power is shut off for a week, a month, or sometimes years, because of accidents or illness can insure themselves against this financial loss by accident and health insurance. Protection is available to all types of workers and the cost(called the premium)ranges from a few cents a day for small or limited policies to a month for policies paying larger amounts(called indemnities). Policy is another name for an insurance contract . Most accident and health policies are cancelable policies--that is, they are sold for a definite term such as a week, a month, or a year, similar to contracts of fire insurance and automobile liability insurance. There are, however, policies which cannot be canceled or terminated by the insurance company until the policyholder reaches an age at which he usually has no further earning power--most often at sixty or sixtyfive years. These noncancelable policies cost more than the cancelable policies. Every year in the United States there are _ . | [

mmlu_train_33856 | More and more people are aware that an afternoon nap can do a body good. But there are still doubters out there. To help spread the power of the afternoon nap, we list some common misunderstandings about napping we still hear. Misunderstanding # 1 : Napping is only for the lazy. Fact: Around a third of American adults nap on the average day, and for good reason: A short nap can improve everything from alertness and memory to creativity and productivity . And none of these sounds like laziness to us! Misunderstanding # 2 : If I take a nap, I'll only wake up feeling worse. Fact: That weak feeling after you wake up from a nap is real (it even has a name: sleep inertia), but it's not a guarantee . How you feel after your nap is a factor of how long you sleep. Experts generally agree that a nap should last no longer than 30 minutes. "If it takes longer than 30 minutes, you end up in deep sleep. You're going into a stage of sleep where you find it very difficult to wake up." said sleep expert Michael J. Breus, Ph. D. Next time you're in the mood for a nap, set your alarm for 20 to 30 minutes, tops. Misunderstanding # 3 : You mustn't nap at work. Fact: In fact, in the office environment, we're all for catching a few winks during the workday. Some companies have even created special rooms for afternoon naps as more and more employers come around to the idea that a well-rested workforce is a more productive workforce. If your employer doesn't offer a place to lay your head, try to find an empty conference room where you can close the door and turn off the lights. Really want. You can also take a nap during your lunch break on a park bench or in your car. Misunderstanding # 4 : I'll be more productive if I just finish this task, rather than waste time sleeping. Fact: Yes, you'll be away from your desk if you spend 10 to 30 minutes sleeping. But you'll likely make up for that "wasted" time afterward. "My research shows that people feel tired after a long time of work during the day," Sara Mednick told Bloomberg Businessweek. "It's difficult to keep energetic and productive all day." However, a nap can leave you feeling refreshed and more ready to deal with the task at hand. Which of the following is the best title for the passage? | [

mmlu_train_55147 | Cosmetic ( ) surgery is usually performed to correct a physical abnormality or to enhance an otherwise normal physical feature and thus improve appearance. Cosmetic surgery is an extremely broad field that may offer reconstructive surgery for a patient after a damaging burn or other physical injuries yet can also be used to smooth out wrinkles or reshape a nose. Cosmetic surgery was first used regularly after World War I, when treatment and reconstruction of war injuries gave hope to young soldiers. As recently as fifty years ago, as the rich and famous began opting for elective cosmetic surgery, the subject was whispered about and considered taboo. Celebrities would disappear for months and then appear after secret cosmetic surgery looking younger, prettier, and thinner. Over time, cosmetic surgery has become accepted and even encouraged in some circles. Today there are even television reality shows about it. Some of the more popular forms of cosmetic surgery are liposuction( ), in which excessive fat is sucked out of the body with a tube and vacuum device; laser facial resurfacing, which smooths lines on the face around the eyes and mouth and eliminates facial blemishes ; and hair replacement surgery, which fills in balding areas using a patient's own hair. There are many more forms of cosmetic surgery, including variations of these.Anyone interested in cosmetic surgery should consider the risks and remember that it is, ultimately, surgery. Not all procedures come out exactly the way doctors and patients foresee, and recovery is just like any other surgery, complete with pain and the possibility of infection . While cosmetic surgery is an option, patients should choose doctors wisely,obtain several references, and keep realistic expectations. What is the author's attitude towards cosmetic surgery? | [

They found those who drank the most green tea were the least likely to develop "functional disability",or problems with daily activities or basic needs,such as dressing or bathing. Specifically,almost 13 percent of adults who drank less than a cup of green tea per day became functionally disabled,compared with just over 7 percent of people who drank at least five cups fl day. The study did not prove that green tea alone kept people active as they grew older. Green-tea lovers generally had healthier diets,including more fish,vegetables and fruit,as well as more education.lower smoking rates,fewer heart attacks and strokes,and greater mental sharpness. They also tended to be more socially active and have more friends and family to rely on. Although it's not clear how green tea might offer a buffer against disability,Tomata's team did note that one recent study found green tea extracts seem to increase leg muscle strength in older women. While green tea and its extracts are considered safe in small amounts,they do contain caffeine and small amounts of vitamin K,which means it could block drugs that prevent blood thickened.

mmlu_train_41093 | Dear Editor , I used to be a doctor in a children's hospital. Sometimes I treated children who had been poisoned by medicines for older family members. The children didn't know the medicine was dangerous; they just knew it tasted sweet. Children easily opened the bottle that we now use in China. Some days ago I talked about medicine with an American. He showed me a kind of plastic bottle. The design was very quite simple and I'm sure our Chinese factories could produce these bottles. The top of the bottle locks but can be opened by pressing down on it while turning. This is difficult for most young children to do, though grown-ups can open these bottles very easily. I'm certain that the price of making such tops would be very low. As a doctor, I'd love to see this done. And most parents would be grateful. Yours, Li Hua The doctor thinks that we should _ . | [
