mmlu_train_84134 | More and more people like bicycling and it is no surprise. It's fun, healthy and good for the environment. Maybe that's why there are 1.4 billion bicycles and only 400 million cars on roads worldwide today. Bikes can take you almost anywhere, and there is no oil cost! If you get on a bicycle and ride it, you may discover something new all around you. Stopping and getting off a bike is easier than stopping and getting out of your cars. You can bike to work and benefit from the enjoyable exercise without polluting the environment. You don't even have to ride all the way. Folding bikes work well for people who ride the train. Just fold the bike and take it with you. You can do the same on an airplane. A folding bike can be packed in a suitcase. You can also take a common bike with you when you fly. But be sure to look for information by getting on airline websites. Not all airlines are bicycle-friendly to travelers. Here are some of Health Benefits of Bicycling: 2 Bicycling helps to prevent heart diseases. 2 Bicycling helps to control your weight. A 15-minute bike ride to and from work three times a week burns off five kilos of fat in a year. 2 Bicycling can improve your mood.

mmlu_train_17641 | Do you have back pain or difficulty with your eyesight? If you do, you are likely to have a problem of posture, which can be solved if you ask a help from a doctor promptly. The conference on posture held in Rome this year has brought out the fact that an Italian out of four have posture problems. Back pain is certainly the typical disease deriving from a wrong posture, which can also cause other problems: sight problems, for example, which affect above all children. You might think that women are most affected by these problems, as they are more used to following the trends of fashion, which imposes the use of heavy bags, flat pumps or high-heeled shoes, but the latest conference of the Italian Society of Orthopedics and Traumatology has brought out the fact that men also have bad behavior. About two millions Italian men suffer from backache. Besides wrong shoes and the habits of keeping the wallet in the back pocket for a long time, hi-tech products can cause some serious problems: laptops, iPads, smartphones...all these electronic products together can weigh up to 5 kilos, while the maximum weigh to carry on shoulders should be 3 kilos. The handiness of modern netbooks can have negative consequences, as you can use them when you are lying down. However, it would be better to use them while seated, keeping your back straight and your shoulders relaxed. If you do not disregard the problem and you intervene in it in time, you can start having a right posture, perhaps doing posture correction exercises and more sport. A global posture re-education , a healthier lifestyle and a series of little devices might solve your back problems. According to the writer the posture problems happen_. | [

mmlu_train_44170 | You'd be forgiven for thinking that running after children each day would leave parents in the best shape of their lives.But a study has found that the mothers and fathers of young children are more unhealthy than their childless peers . Mothers with young children are heavier and eat more calories and fatty foods,and consume more sugary dinks than chidless women,scientists said.And both sexes are less active than those in their age group without children. Parents often choose quick,easily preparesd foods that are high in fat and calories,and by choosing these foods they may in turn serve them to their children,forming a cycle of unhealthy diet. Dr.Berge,one of the study authors,said:"This isn't a study about blame,this is about spotting a very high-risk time period for parents that doctors should be aware of ,so they can offer solutions ." According to the study ,mothers ate more fatty foods and drank about seven sugary drinks weekly,equal to about four chidless women.They also had an average of 2,360 calories daily,368 calories more than women without children,With that many calorise,women that age would need to be active to avoid to avoid gaining weight. Fathers ate about the same amount of daily calories childless men and both had an average boby-mass index ,but fathersgot less physical activity--about five hours weekly ,compared to almost seven hours among chidless men. The study has several limitations-there's no data on how many women reccently had babies.Ther's also no information on the number of single parents,who likely face diet and exercise challenges.Sarah Kriger,an American dietician who works with new mothers said some of the mothers may have had postpartum depression,which might affect their eating and exercise habits.

mmlu_train_74959 | Is your TV connected to the Internet? What about your chair,or your fridge? Probably they are not. But in the future, most things in your home may be connected, thanks to the so-called "Internet of things". The Internet of things may be coming sooner than you think. Earlier this year, A Samsung CEO spent a lot of time talking about the Internet things. He said that five years from now,every Samsung product will be part of the Internet of things,no matter whether it's a remote control or a washing machine. So, how do household objects that are part of the Internet of things work? Well,think of a common chair. When connected to the Internet, the chair warms up when it knows the user has just walked into the room and is feeling cold. An Internet-connected camera could help people feel safer in their homes. It can know people's faces and has an infrared sensor ,so even if it's dark it can see when someone passes by and send you a message on your smartphone to let you know who's there. If the person is someone you don't know,it can tell you that ,too. But according to MIT Technology Roview, whether companies are connecting dog food bowls or security systems to the Internet, there may be some problems. For example, many early connected-home objects don't have much built-in security, which means they could be hacked . Morever, it could be difficult to get these new machines to work together especially when they are made by different companies. To fight this ,many companies have joined the Open Interconnect Consortium, which had 45 menbers by late 2014. So, picture this: you enter your home.The temperature changes to make you feel comfortable. Your favorite music starts playing for you. Do you think that this would be a good thing?

mmlu_train_28187 | 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.

mmlu_train_27092 | If music makes you smarter, and exercise helps brain function, can exercising to music really boost brainpower? Some researchers said it could. Volunteers who listened to Vivaldi~ "Four Seasons" while working out on a treadmill did much better on a test of verbal ability than when they exercised without music, a team at prefix = st1 /OhioStateUniversityfound. "Evidence suggests that exercise improves the cognitive performance of people with coronary artery disease ," said psychologist Charles Emery, who led the study. "And listening to music is thought to enhance brainpower. We wanted to put the _ together," Emery added in a statement. Writing in the latest issue of the journal Heart & Lung, Emery and colleagues said they studied 33 men and women taking part in a cardiac rehabilitation program after having bypass surgery, angioplasty or other procedures to treat clogged arteries. The volunteers said they felt better emotionally and mentally after working out with or without the music. But their improvement on the verbal fluency test doubled after listening to music on the treadmills ."Exercise seems to cause positive changes in the nervous system, and these changes may have a direct effect on cognitive ability," Emery said. "Listening to music may influence cognitive function through different pathways in the brain. The combination of music and exercise may stimulate and increase cognitive arousal while helping to organize cognitive output." Emery said he now wanted to test people using music of their own choice. "We used The Four Seasons' because of its moderate tempo and positive effects on medical patients in previous research," Emery said. "But given the range of music preferences among patients, it's especially important to evaluate the influence of other types of music on cognitive outcomes."

mmlu_train_15922 | Man has been to the moon. It has been the first step towards future exploration in space. When compared with the distances between Earth and the other planets, the distance between the Moon and Earth is very short indeed. Mars, the nearest planet to Earth is millions of miles away! Traveling to the planets will be man's next step. Such travels will be more challenging than the trip to the moon and certainly more exciting and dangerous. Recently, two American spaceships, Viking 1 and 2, landed on Mars trying to discover whether that planet has any life on it. So far the signs of life on Mars has neither been confirmed nor ruled out . Russians have discovered that the surface of Venus is so hot that it is almost certain that there is no life there. Also the atmosphere of Venus is extremely dense and the pressure is nearly a hundred times greater than that of the Earth's atmosphere.

mmlu_train_73862 | According to scientists' research, the month in which babies are born could affect them in some ways. Babies born in spring get sick easily. Children born under Aquarius may be less clever than those born in other seasons. They may also have shorter lives than those born in autumn Scientists believe many of the differences can be explained by the mother's exposure to sunlight in pregnancy . Sunlight helps lead to the production of Vitamin D in the body. The lack of this in the first months of life may have a bad effect on mental and physical health. Vitamin D, called the "sunshine vitamin", is known to help regulate thousands of genes during development, according to a study of more than two million people. So Vitamin D has a good effect on health This study showed that people born from April to June had slightly shorter lives than those born in October, November or December. Similar studies in the USA showed that people born in autumn lived about 160 days longer than those born in spring. Professor Russell Foster, an Oxford University neuroscientist on seasonal biology, said the conclusions were surprising and interesting.

mmlu_train_27806 | "It's this time of year when the weather starts warming up and frogs start breeding - but they haven't been breeding," says John Wilkinson, research and monitoring officer at the Amphibian and Reptile Conservation Trust (ARC). Amphibians are just one of the groups of animals that nature observers fear may have problems reproducing this year, as groundwater levels are even lower now than in the infamously dry summer of 1976, according to the Department for Environment, Food and Rural Affairs (Defra). According to the UK's Centre for Hydrology and Ecology the average rainfall so far this winter has been the lowest since 1972. "If ponds dry up totally," says Mr. Wilkinson, "you could have lots of dead tadpoles." Drier and windier conditions could also make it more difficult for juvenile amphibians to survive their journeys between wet habitats. But Peter Brotherton, the biodiversity manager for Natural England, says that "drought is part of nature's cycle", and, at present, a lot of animals, plants and insects are still in hibernation. This means that the population picture is unclear. "However, when we get extreme events, we get animals dying," he says. "And what is worrying is that normally at this time of year we expect soil to be near saturation after winter." Charlie Kitchin, the RSPB's site manager of the Nene Washes in Cambridgeshire, says the 2,000-acre wetland and grassland area is now struggling following two winters with relatively little winter rain and no flooding. One species that could suffer, he says, is the black-tailed godwit . "There are only 50 breeding pairs in the country, and we have 40 of them, and everything is bone-dry," Mr Kitchin says. But one bad nesting season, he says, is "not the end of the world". "One of the features of flood plains is that they're _ anyway," he adds. "But if they fail to breed another year, the population is likely to dip again." What really worries Peter Brotherton is that _ . | [

mmlu_train_16054 | What's delicious to eat and comes in a variety of color1s? Eggplant! And no, it has nothing to do with chickens! This strangely named vegetable is, however, as versatile as an egg.It can be steamed, fried, and baked.It can be eaten by itself or combined with meats and other vegetables. Eggplant was first grown in India in the 5th century BC. Its popularity soon spread to China and then throughout Asia.Finally, during the Middle Ages the vegetable made its way to Europe. At that time, eggplant was not the shiny purple vegetable most people know today.Instead, it resembled a white egg. Due to this egg-like appearance, eggplant got its name.In its early days, the vegetable was so bitter that people often called it a "mad apple." This nickname started because people believed its bitterness was bad for one' s health. People actually thought eggplant could cause insanity and cancer. Fortunately today people know that eggplant doesn't cause insanity or cancer.In fact eggplant is so healthy that it may prevent cancer.In addition, the brain and the heart benefit from this super vegetable.Since it's high in fiber, eggplant can improve digestion. Italy, Turkey, Egypt, China and Japan are the leading growers of eggplant in the world today.Depending on its location, eggplant may be purple, green, orange or yellow-white.And it can be as small as a tomato or as large as a cucumber.Dish varieties range from simple to complex, with all of them being delicious.

mmlu_train_18132 | Film cameras and digital cameras work in a similar way. Film cameras After all, a film camera is basically a light - proof box. It has a lens system to focus light onto the film at the back of the camera. Let's suppose that we are outside on a beautiful summer day trying to take a picture of the family dog. We are using a film camera. We finally get the dog to lie still. You point the camera at him. What happens? Light goes into the camera lens and hits the shutter. In other words, nothing happens yet. Now let's say that the dog looks really cute and you decide to snap a picture. What happens? When you press the button, the shutter opens for a very short period of time. A small amount of light passes through and hits the film at the back of the camera. This creates an upside-down and reversed image on the film. When you finish the roll of the film, you can take it to the photo shop to develop it and you will have a great picture of your dog! Cameras come with different lens lengths. Why does it matter? Many small cameras have shorter focal lengths, which means that there is a small distance between the lens and the place where the light focuses at the back of the camera. This gives you a large view of the area you are taking a picture of. Lenses with a long focal length show a smaller area but allow you to focus on distant objects and make them bigger. They are often called telephoto lenses. A good example of a long focus lens is one that is used by sports photographers to get photos of football players as if they were standing right beside them. Digital cameras In digital cameras, the light falls not on film but onto a sensor called a CCD (Charge Coupled Device). This digitally converts light and color into a digital information or pixels . The CCD is the heart of any digital camera and usually the most expensive part ---- depending on how good it is. Generally speaking, a digital camera's price is _ . | [

"You can't keep away from it, for the simple reason that whenever a new variety of language comes along,it inevitably influence the language as a whole."Says Dr David Crystal,honorary professor of linguistics at the University of Wales in BangoL, whose book "Language and the Internet" has just been published. The trouble with keeping up with the new English is not so much that there are so many new words but that the old words no longer mean what we thought they did.In the past, if someone said they did not have Windows,you would have to suppose they lived in a cave.These days, it is probably because they use a Mac(which is a computer,not a rain coat).Spam is as disliked as it ever was,but whereas it once meant an unappetizing canned meat.It now stands for unwanted 'junk" email.Spellings are changing,too.Not only is text-messaging playing "hvc with vrbs" (havoc with verbs),but the conventions of email communication place little emphasis on "perfect speaking". Weblish loves to see nouns happily become verbs ("please bookmark this site"),and verbs become nouns ("Send me the download").Verbs and prepositions are regularly thrown together to become new nouns or adjectives(dial--up,logon,print-on,pull--down,upload),while others are created from simply pairing nouns:cyberspace,emit Internet,hyperlink,metatag,netspeak.

Biomass energy in the prefix = st1 /United Statescontributes 2.5 percent of the total supply, but this amount can be doubled by 2017 and then doubled again by the year 2027. Eight percent of Sweden's energy supply, for example, is presently coming from wood and pulp remaining. Swedenintends to raise this percentage by more intensive harvesting of waste food lying around in forests, and through the planting of so-called energy forests of fast-growing trees such as willow. Brazilis frequently pointed to as a nation with a major successful investment in energy coming from grains: it presently runs 330,000 automobiles on a water and alcohol mixture, replacing 10 percent of its previous oil supply.

This slowest-moving member of the animal kingdom is so inactive that moss actually gathers on its body and turns it green -- strange as it seems! Most of the sloth's life is spent motionless, hanging upside down from a limb . And that is the way its hair grows. Long and coarse, the strands from receptacles for the damp jungle algae turn the brown fur a mossy green. Actually this moss helps the animal survive because it serves as a perfect camouflage against the leafy trees and hides the sloth from the jungle's swift-moving hunters. The sloth would have little chance of survival on the ground. With long, curved claws hooded over the limb of a leafy tree, it spends the long hot hours during the day drowsing and eating. Inch by inch, it strips the leafy limbs bare and crawls slowly down the trunk to find a new dining spot, but only at night. In addition to looking rather like a vegetable, the sloth is a strict vegetarian. Running out of its favorite leaf is about the only thing that will make a sloth move. Then its appetite may even force the animal into swimming a stream to reach a succulent . It will also force it into fighting to keep the tree all to itself.

People tried for centuries to invent the typewriter.In 1714 in England,Henry Mill filed a patent for a machine called An Artificial Machine Or Method for the Impressing or Transcribing of Letters,Singly or Progressively one after another, as in Writing,whereby all Writing whatsoever may be Engrossed in Paper or Parchment so Neat and Exact as not to be distinguished from Print.That machine probably didn't sell because no one could remember its name! The first practical typewriter was patented in the United States in 1868 by Christopher Latham Sholes.His machine was known as the type-writer.It had a movable carriage,a lever for turning paper from line to line,and a keyboard on which the letters were arranged in alphabetical order. But Sholes had a problem.On his first model,his"ABC"key arrangement caused the keys to jam when the typist worked quickly.Sholes didn't know how to keep the keys from sticking,so his solution was to keep the typist from typing too fast.Sholes asked his brother-in-1aw to rearrange the keyboard so that the commonest letters were not so close together and the type bars would come from opposite directions.Thus they would not clash together and jam the machine.The new arrangement was the QWERTY arrangement typists use today.Of course,Sholes claimed that the new arrangement was scientific and would add speed and efficiency.The only efficiency it added was to slow the typist down,since almost any word in the English language required the typist's fingers to cover more distance on the keyboard. The advantages of the typewriter outweighed the disadvantages of the keyboard.Typists memorized the crazy letter arrangement,and the typewriter became a huge success.By the time typists had memorized the new arrangement of letters and built their speed,typewriter technology had improved,and the keys didn't stick as badly as they had at first.

According to the Centers for Disease Control and Prevention,more than 126 million Americans who don't smoke are exposed to secondhand smoke in their homes,vehicles,workplaces,and public places.This exposure causes thousands of lung cancer and heart disease deaths among nonsmokers every year,according to the California Environmental Protection Agency. "Making the leap from the effects of secondhand smoke on humans to their effects on pets isn't a big one," says veterinarian Carolynn MacAllister of Oklahoma State University. "There have been a number of scientific papers recently that have reported the significant health threat secondhand smoke poses to pets," MacAllister said."Secondhand smoke has been associated with oral cancer and lymphoma in cats,lung and nasal cancer in dogs,as well as lung cancer in birds." Studies have also shown that dogs living in a smoking household are susceptible to cancers of the nose and sinus area,particularly if they are a long-nosed breed,because their noses have a greater surface area that is exposed to carcinogens and a greater area for them to accumulate.Dogs affected with nasal cancer normally don't survive for more than one year. "Short and medium-nosed dogs are more susceptible to lung cancer,because their shorter nasal passage aren't as effective at accumulating the inhaled secondhand smoke carcinogens," MacAllister said."This results in more carcinogens reaching the lungs." Birds are also at risk for lung cancer,as well as pneumonia,because their respiratory systems are hypersensitive to any type of air pollutant. To help prevent animals from being adversely affected by smoking,pet owners who smoke should have a designated smoking area that is separated from the home or stop smoking altogether,MacAllister said.

The investment in higher education, whether financial or in terms of time, has long been impossible for many of them. But well-known educational institutions have chosen to deliver an internet-based program, and these barriers have been lifted. That is good news for people eager to improve themselves and is more attractive to employers. It is also a benefit to industry with better qualified candidates applying for jobs at every level. Having the benefits of a higher qualification without going to the university campus is attractive to many students. Campus study means greater cost, while online programs are flexible and save time, whether at home or at work. Students can achieve their degrees without causing too much _ to their career or home life. In addition to affordable, flexible classes and greater convenience, students also have access to the online learning resources of many of the world's top educational institutions. They can also communicate with their tutors no matter what time it is or whether either party is away for any reason. This has opened up the possibility of getting a qualification from a university or college that many students could only have dreamed of in the past. It also allows specialists to get the precise qualifications and focus on their studies. As well as seeing the increase of applicants from lower-incomes and housewives, studying online in the US is even becoming popular with younger people of college age. Employers have become increasingly welcome and positive to online qualifications as more candidates earn them, especially if they're properly approved by the US Department of Education.

mmlu_train_37855 | It is common to have difficulties sleeping during the day. Humans are naturally wired to sleep best at night and be awake during the day. However, modern work schedules require some people to try to accommodate the unnatural schedule of shift work -- being awake at night and sleeping during the day. In order to make this adjustment, you need to pay special attention to your sleep environment and your preparation for sleep. If shift work is a necessary part of your work life, here are some suggestions that may help. Arrange to sleep uninterrupted in a quiet, dark room. This means you may have to turn off or unplug your phone, hang darkening curtains on the windows or wear a sleep eye mask, and train your family and friends to leave you alone while you sleep. Fit in a nap . When your daytime sleep period is too short, taking a short nap of less than 30 minutes just before work or on a break has been shown to improve alertness and enhance performance. Develop and follow a sleep routine. It's best if you go to sleep and wake up at the same time every day. Try not to vary this too much on weekends. Your body likes routine. Take extra care to make healthy choices. You may be tempted to reach for unhealthy foods or nicotine to stay awake or alcohol to try to sleep. But ultimately these choices are more harmful than helpful. If you have tried all these things and are still having problems getting enough quality sleep during the day, talk to your doctor or a sleep specialist. Sometimes medications may be helpful and safe. In other cases, there may be an underlying sleep disorder that needs to be addressed. What does the author recomusend? | [

mmlu_train_48591 | While very young unmanned aircraft industry looks at ways to improve small unmanned aircraft systems (UAS) for specific tasks such facility security, infrastructure inspection, or precision agriculture, a New Mexico-based aerospace founder is thinking bigger and longer-term ones. Titan Aerospace, a one-year-old aircraft designer, last week unveiled its Solara 50 and Solara 60 unmanned aircraft. These are two large solar-powered>> high-altitude vehicles the company plans to send up into space for weeks,months>> and eventually years at a time without ever having to land. Titan doesn't refer to these concept aircraft as "drones " or "unmanned aircraft system," but instead calls them "atmospheric satellites" for their ability to remain in the sky for extended periods of time just as orbital satellites do. The company hopes to provide a platform of less than $2 million that governments, private industry, and research institutions can put high into the atmosphere for extended periods of time for a little part of the cost of a space satellite. The idea is that an atmospheric satellite can conduct most of the same operations as an orbital one: atmospheric observation and weather monitoring, communications relay, oceanographic research, and earth imaging. Other operations are impractical for space satellites, such as border security, maritime traffic monitoring and anti-piracy operations, disaster response, or agricultural observation. And with continuous flight time of up to five years, Solara's aircraft would have endurance on par with (......) many small satellites, making them a more attractive choice for a range of these applications. "If you have to go up to the orbital satellite and rent that service>> that's a lot of money," says Dustin Sanders, Titan's chief electrical engineer. "And launching a satellite, that can cost billions of dollars. We're trying to do a single-million-dollar-per-aircraft platform.

mmlu_train_42411 | (CNN) -- In the last week, the Apple iWatch has made the jump from unlikely rumor to a real product that's probably in development, thanks to reports showing up in various publications. The clues are planting the seeds of an Apple watch in consumers' minds. The general public has not been crying out for a better watch. And Apple prides itself on knowing what the people want before they do, and an Apple watch would be much more than just a fancy timepiece. It's not about the watch form factor, but creating a wearable mobile device that takes advantage of advances in mobile computing technology such as cheap sensors, better battery life and improved voice recognition. If executed correctly, an Apple watch could bring about a profitable industry of products to go with it, like it did with the iOS App Store and mobile applications. "It's unlimited, the number of wearable things you can put into," said Gene Munster, an analyst with Piper Jaffray, who imagines small companies making inexpensive products like belts with sensors that send warnings to the watch when you've eaten too much. Apple is not entering virgin territory. There are already a handful of fancy smart watches available, but most act as accessories , connecting to the more powerful Android and iOS smartphones and tablets over Bluetooth. For example, the new Pebble smart watch passes on alerts from a smartphone, so when you receive a text, e-mail, or Facebook notification it is pushed to the watch, which vibrates . Wearable technology is also booming, thanks to cheap sensors that can be used to track things like movement and heart rates. The number of wearable fitness products has been growing at a fast pace, but an Apple offering would shake up the industry completely. "We're finally getting some players involved, and Apple is the real one that can add some value to some of this wearable technology," said Munster. Apple isn't alone in seeing the potential for this type of technology. Google is working on its own wearable platform, Google Glasses. The two will compete against each other when they are finally available, each sporting its own unique opinion on what kind of user interface people will use (voice control and a small touchscreen or augmented reality). And they will, of course, have their own ecosystems of accessories and apps. Traditional watches have dropped in popularity in recent years. Smartphones display the easy-to-see time and are already in our back pockets, so it can seem unnecessary to also tie a small clock to our wrists. But when you start packing more power, sensors and connection options like Bluetooth into a watch, it no longer stays to be a watch and becomes a small wearable computer. An Apple watch could suddenly become better than the current crop of smart watches by creating a platform, not another accessory. According to Munster, the three tasks people use their smartphones for are, in order, texting, Internet and phone calls. Two out of three of those tasks would be a natural fit for a small device, while the need to surf and play games would ensure the smartphone doesn't become out of date.

mmlu_train_45535 | Children with autism have difficulty with social skills and communication. They often behave in restricted and repetitive ways and have what seem like abnormally intense interests. Autism is more common in boys than girls. What causes it is not clear. Scientists are studying genes and possible environmental influences. Doctors usually cannot confirm a diagnosis of autism until a child is about three years old. Rebecca Landa is a researcher at the Kennedy Krieger Institute and Johns Hopkins University School of Medicine in Maryland. Professor Landa wanted to find out what differences in development might be seen earlier. She led a new study that observed 235 babies between six and 36 months of age. "At six months of age, the signs of some risk for developing communication and social delays, including autism, include motor delays. Like when you lay your baby on their back and you pull them by the arms gently into a seated position, the baby's head may nod back behind the shoulders, like poor head control. So that does not mean that the baby is going to have autism, but it does mean the baby needs to have some exercises to strengthen their body. And when they strengthen their body, they are better able to play with toys and engage with people, which then goes on to help them have better outcomes." By the time a baby is one year old, signs of possible autism include difficulty in using words and not looking eye-to-eye or reaching out to other people. By 14 months, the baby might smile less and use language less. However, Professor Landa says these signs can be so small that they might be missed during a short health exam. "It's important for parents to stay tuned into their children's development, and if a parent is concerned about a child's development, for professionals to listen to them." The earlier parents notice delays, she says, the sooner they can begin doing simple things that may help improve their child's development. For example: talking to the child about what they are doing, commenting when the child shows them something, and playing simple games that keep the child's attention. When a baby with signs of possible autism is a year and two months, he may _ . | [

mmlu_train_35650 | Pumpkins are not only the most important symbol of Halloween; they are the star vegetable in decoration and cooking uses. Often, we pay no attention to how many different ways it can be used. The pumpkin is a wonder vegetable. It includes vitamins A, C, E, fiber, minerals and so on. It is also low in salt. When buying your pumpkins, always get them from your local farmers to support their business and the environment, also you can make sure that they are freshly grown. If you are feeling interested, you can grow your own pumpkins! When carving your jack-o'-lanterns, don't throw away the seeds! They are delicious when they are fried, which is healthy for you. When your jack-o'-lantern is useless, don't throw it away at once. Instead, put it in a certain place and let nature do all the work. Be sure to remove the candle inside, and cut the pumpkin into pieces. Those remaining parts will help your soil. Make a pie--a great way to bring family and friends together. If you are feeling even more interested, try cooking something new with the pumpkins and see what wonderful delicious dishes you can produce in your very own kitchen. And don't think of the pumpkin just around Halloween--it's great all year round. The writer suggests you buy pumpkins locally because _ . | [

mmlu_train_36957 | Standard English is the formal English that you need to use when you write in coursework or in the exam. Standard English is the form of English you learn in school. All written English should be standard -- that means it should be clear enough for anyone in Britain to understand it. Standard English developed as the main form of printed English in the 15th Century. At the time, every region of Britain used to spell words differently, but printers needed a fixed spelling. Printers like Caxton chose the East Midlands dialect form which was used in London and the South East. Soon Standard English replaced all written dialect forms -- the other forms of English spoken around the country. It also replaced French and Latin in law and in academic work. In the 18th Century, people wrote dictionaries and grammar books which standardized spelling -- Dr Johnson's Dictionary of 1755 fixed many of the spellings we still use today. All written English should be Standard English -- any grammar rules you learn are for Standard English and you will definitely need to learn them to avoid making mistakes in your work. The rules of Standard English mean using the correct forms of words with the correct spellings. Avoid slang words -- words that your teachers or friends wouldn't understand. You'll lose marks if the examiners can't understand what you say or write. Don't use dialect words. Every region has words or phrases that are only used there. Don't use them in your coursework, because you won't be understood. Make sure you revise grammar and punctuation you have learned, and learn the list of commonly misspelled words you have made. Cliches are ideas or sayings which have been used so often that they've become boring and unoriginal. Phrases like, "As good as it gets" "At the end of the day" "In the fullness of time" are all cliches. So are images like, "as fierce as a lion" "as cunning as a fox". If you use them you will sound boring and unimaginative -- that could mean you lose marks for writing and speaking style. So avoid cliches. Which statement is true? | [

mmlu_train_66548 | How long has 3-D technology been around? Most of us might think of crowds of teenagers in a 1950's movie house watching Bwana Devil in 3-D. But 3-D technology made its first appearance on the scene in 1838 with the first stereoscope . And the first actual 3-D movie was a 1903 film called Le Ariveed'un Train. Although it has such a long history, the technology has still remained based on one simple principle-----to make 3-D effects you must find a way to project two slightly different pictures to each eye. Modern 3-D technology works by rapidly flickering two versions of the movie and projecting them onto each eye. The brain does the rest of the work, combining the two pictures together into one and giving the show the appearance of depth, the third dimension. But does this exposure, especially long exposures, cause harm to the child's developing brain and visual system? Unfortunately, long-term studies on new flicker digital 3-D technology and children aren't yet available. We do not know if regular or daily 3-D viewing over years affects the developing visual system, although older 3-D methods basically do the same thing and are not considered harmful. The question of possible harm in modern 3-D use in TV is really based on two facts: the amount of time children will now be watching 3-D TV each day and the sensitivity some children show in reaction to 3-D viewing. It is difficult to make actual lab studies of longer term 3-D viewing in children because of the possible harm of the experiment. Researchers will have to wait until 3-D TV technology is already in the marketplace for a number of years, then check heavy 3-D TV watchers and compare them with non-watchers. With a 3-D television technology in the home, we will soon be able to answer the question of whether or not longer and more frequent periods of 3-D exposure cause more changes in the visual system. We may find that the bigger problem is the introduction of a new technology that leads to even more time spent on TV rather than playing outdoors. According to the text, 3-D technology _ | [

mmlu_train_32251 | Caffeine not only gives us a daily jump start, but new research suggests it also can strengthen long-term memory. According to the US Food and Drug Administration, nearly 90 percent of people worldwide consume about 200 milligrams of caffeine each day. That' s equivalent to about one strong cup of coffee a day. Writing in " Nature Neuroscience" , Johns Hopkins University researchers say their findings show that caffeine strengthens certain memories for up t0 24 hours after being taken in. " We've always known that caffeine has cognitive-enhancing effects , but its ,particular effects on strengthening memories and making them resistant to forgetting has never been examined in detail in humans, " said senior author of the paper Michael Yassa. " We re- port for the first time a specific effect of caffeine on reducing forgetting over 24 hours. " Conducting a double-blind trial, the researchers worked with a test group of people who didn't regularly consume caffeinated products. Five minutes after studying a series of images, the test subjects were given either a placebo or a 200-milligram caffeine tablet. To check the caffeine levels of their test subjects, the research team took saliva samples from them before they took their tablets and again one, three and 24 hours after- wards. Both groups of test participants ( those who took the placebo and those who took the caffeine tablet) were tested the following day to see if they could recognize the images they' d seen the previous day. The test included showing the test subjects another series of images that included some new images , those that were shown the previous day, as well as other images that were similar, but not the same as those they had viewed earlier. The researchers found that more members of the group who were given the caffeine tablets were able to correctly identify some of the new images as " similar" to previously viewed images rather than incorrectly identifying them as the same. "We also know that caffeine is associated with health and longevity and may havesome protective effects from cognitive decline like Alzheimer' s disease . " said Yassa.

mmlu_train_37491 | People who offer love, listening and help to others may be rewarded with better mental health themselves, according to a new study of churchgoers in the September/October issue of Psychosomatic Medicine. The study is one of the first to track the positive health benefits of altruistic behavior, says Carolyn Schwartz, Sc.D. of the University of prefix = st1 /MassachusettsMedicalSchool. "The findings really point up how helping others can help oneself," Schwartz says. Schwartz and his workmates analyzed the information collected by the Presbyterian Church for 2,016 church members. The members were asked about how often they "made others feel loved and cared for" and "listened to others", and how often they received this attention in return. The members also answered the questions about their mental and physical health. Most of the church members were in good physical and mental health to begin with, experiencing only normal levels of anxiety and depression. While the researchers did not find any significant differences in physical health clearly related to giving and receiving help, they concluded that giving help was a better predictor of good mental health than receiving help. But feeling crushed by others' demands can have negative psychological effects, according to the researchers. "Although our findings suggest that people who help others experience better mental health, our findings also suggest that giving beyond one's own resources is related with worse reported mental health," Schwartz says. Church leaders, older people, women and those who took satisfaction from prayer were more likely to be helpers rather than receivers, according to the study. People who give help to others may be less likely to focus inward on their own anxieties and depression or more likely to see their own troubles in mind, leading to better mental health, say the researchers. Alternatively, it may be that "people who are functioning well psychologically are better able and hence more likely to give help," Schwartz says. Which of the following is NOT mentioned in the passage? | [
"Older people are more likely to help others.",

mmlu_train_49759 | Scientists have argued for long over whether birds show real intelligence. Some scientists believe birds have abilities including communication and different kinds of memory. In some unusual cases, their abilities seem better than those of humans. Irene Pepperberg, a birds expert, did research about a grey parrot named. Griffin. Ms. Pepperberg says Griffin can arrange objects in order of size. She says the talking bird also can combine words in the right order. For example, he will combine words when asking for a piece of food. The researcher says experts had thought that only humans and other mammals with large brains have the ability to combine objects and words. She believes that bird brains have the ability to understand that complex tasks must be done in the correct order. Some birds have other memory skills. For example, they collect and store thousands of seeds in autumn, and find them later in winter. Alan Kamil and Alan Bond of the University of Nebraska are studying the memories of birds called jays and nutcrackers. Their experiments show that these birds use natural objects to find the seeds they have stored. It's said some birds can learn as many as 2,000 different songs. Songs may have developed as a way for birds to communicate with other birds. According to Verner Bingman of Bowling Green State University in Ohio, birds must have a special guidance system in their brain. He says that understanding how a bird's brain operates may help us better understand how a human brain processes information. However, some scientists do still believe birds do many things that appear to be acts of thoughtful intelligence. In most cases, they say, their behavior is simply instinctive , no reasoning power directing it. What is the main subject discussed in the passage? | [
