mmlu_stem | mmlu_stem_6957 | A schoolboy, who has been unable to play sports, has found the perfect entertainment--snowboarding. Thomas Pettigrew is enjoying himself by performing difficult actions at freestyle events. The youngster can't join in PE lessons at school, because he suffers from a rare condition, which means his body dangerously overheats. This makes it difficult for his body to cool down naturally. But the ice-cool temperatures on the mountains mean Thomas can slide down the slopes freely. His father Richard came up with the idea of taking Thomas snowboarding in March, 2010. Now while other children look forward to playing outside in the sunshine, Thomas is applying his new activity at the Snow Zone in Castleford, in temperatures of about -5degC. Mr. Pettigrew said, "When Thomas tries most sports, he has to stop when he gets too hot but that never happens with snowboarding. I was surprised at how good he was when he started. He now goes every week for three or four hours. He's been so enthusiastic about his snowboarding that he's even persuaded me to have a go, so we can enjoy it together." Thomas's parents have spent the past 10 years watching the schoolboy for any signs of overheating, only taking him on holiday in the cooler months. "He has no energy and no interest in doing anything if he overheats and we do whatever it takes to cool his temperature, such as putting him in the car with the air conditioner working or running cold baths." Aiden Harington, head of the ski school at Snow Zone, said, "Snow sports are a great way for anyone to keep fit, but seem to be particularly beneficial to Thomas as he is able to make sure he stays cool. Thomas does very well in snowboarding, and he can now perform plenty of freestyle actions. I'm sure that he will continue to progress in the coming months, and hopefully take part in some of our freestyle events." Thomas Pettigrew thinks snowboarding is _ . | [

While a personal computer should continue to perform well for years, users know that system unsteadiness does exist Yet you can reduce it to the smallest amount by following the tips below . First, put in as little software as possible. You'11 have fewer software -related problems and a system that is easier to manage. Second, you should ensure that you have as much memory (RAM) in your PC as you need If you run Windows 98,your computer should have as least 128 megabytes (MB)of RAM and more You can also get by with 128 MB of RAM if you use Windows NT or Windows2000,but these operating systems will run much more smoothly if you have 256 MB of RAM or more. Third, make sure you buy good hardware. Noname products may be cheaper and sometimes just as good as named-brand products, but name-brand products usually became well-known because of famous companies because Windows will more often support the hardware that you buy ,If you are starting out with to have been tested thoroughly with your operating system, and you will generally experience fewer problems. Fourth, do prepare for disaster .No matter how well your system runs when you get it ,the day will come when it will need to be replaced .Hopefully, you will replace it because technology has become outdated, but you may need to replace it also because the hard drive crashes or you begin experiencing problems that no one can figure out .That's why it 's important to you're your important to copy your important information regularly.

Interestingly, all the Scottish Folds are born with straight and unfolded ears. And when they are growing up day by day, some cats' ears will begin to fold. So, the Scottish Fold comes in two types: folded ears and straight ears. There is a nickname for the Scottish Fold. It is the "Messenger of Peace". Why? Because the Folds are sweet and friendly animals. They can _ with other cats. And unlike some other cats, they can even get along well with dogs!

mmlu_stem | mmlu_stem_12541 | One day, a man found the cocoon of a butterfly and he brought it home. A few days later, the man saw a small hole in the cocoon. He sat and watched for several hours as a butterfly struggled to force its body through that little hole. Then it stopped. So the man decided to help the butterfly. He took a knife and cut a bigger hole in the cocoon. The butterfly came out of the cocoon but it had a weak body and small, thin wings. The butterfly didn't start to fly. In fact, the butterfly spent the rest of its life crawling around with a weak body and thin wings. It was never able to fly. The man acted with kindness but he didn't understand that he had done something wrong. When a butterfly crawls out of the cocoon, it must struggle. The hard work of getting out of the cocoon forces the fluid from the butterfly's body into wings. It helps the butterfly be ready to fly. If the butterfly never has to force itself out of the cocoon, its wings never get the fluid and it can never fly. Sometimes struggles are exactly what we need in our lives. If we lived our lives without any problems, we would never learn or grow. We would not be as strong as we could have been and we would never fly. So, the next time you are faced with a challenge or a problem, remember the butterfly. Struggle a little - then fly! Why couldn't the butterfly fly? Because _ . | [

mmlu_stem | mmlu_stem_2969 | It's the dirty little secret many shampoo companies don't want you to know. When you wash your hair with certain traditional chemical shampoos, you may actually be removing your hair and scalp of their natural oils. These shampoos generate a thick bubble to clean hair, they can also create dryness, curl, dullness, and color fade. We then spend a lot of time and money on products that are effectively repairing the damage caused by shampoo. Chaz Dean got tired of clients leaving his salon _ t their color and the feeling of their hair---brassy and dull. He knew the main cause was likely their shampoo, so he started experimenting with various ingredients, including natural herbs and botanicals, that he knew had cleansing and hydrating properties. The result was a totally new approach to the way we cleanse our hair. It's called WEN(r) Cleansing Conditioner. WEN(r) contains a super-hydrating natural herbs and botanicals mixture of glycerin, chamomile , rosemary, calendula, and Cherry bark, which when combined, will both cleanse the hair as well as give shine and softness, even to damaged hair. WEN(r) is a 5-in-1 formula that takes the place of your shampoo, And the most amazing thing about it is that it cleanses without bubble. Instead, when mixed with water, it creates a smooth bubble for shiny, healthy-looking, manageable results. The first time you try it certainly feels strange, but the results speak for themselves. Before being marketed, WEN(r) went through extensive consumer tests, and the results were impressive. More than 90 percent of the participants in the studies reported that their hair was more shiny, less frizzy, and had more bounce. WEN(r) is recommended for all hair types, and once you start using it, it will become the only cleanser/conditioner you will want to include in your daily routine. Right now, WEN(r) is offering an easy way for online shoppers to try the product. Now you just pay less than $30 and have a 60 day money back guarantee if you are not completely satisfied.

A medical team completed the 11- hour operation Friday night and said 8-week-old Rebecca Martinez died seven hours later. Doctors had warned after the surgery that the girl would be at great risk of death. " We knew this was a very risky surgery , and now we accept what God has decided , " Rebecca's father , 29-year-old Frankin Martinez, said at a news conference with his wife. " Rebecca is no longer with us physically , but no one will forget her." Martinez said the family would bury Rebecca in a private funeral later in the day. The girl lost a lot of blood in the operation, which apparently ( ) caused her to suffer a heart attack , said Dr. Jorge Lazareff , the lead surgeon . Friends and family donated almost 4 gallons of blood for surgeons to use Rebeca's operation "This was not a failure or an error ," Lazareff said . " When we left here last night the girl was in stable condition. At some point in the middle of the night , she started to bleed." Rebecca was born Dec. 10 with the undeveloped head of her twin, an exteremely rare condition known as craniopagus parasticus . Rebecca was the eighth documented case in the world of craniopagus parasiticus, doctors said. All the other infants documented to have had the condition died before birth , making Rebecca\s surgery the first known operation of its kind. Without an operation , Rebecca would have barely been able to lift her head at 3 months old. Her doctors said the pressure from the second head would have prevented her brain from developing. " We always saw Rebecca without the extra part of her body, "er father said after her death. Rebecca was their third child-----along with a 4-year-old boy and a 1-year-old girl.

mmlu_stem | mmlu_stem_8028 | People diet to look more attractive.Fish diet to avoid being beaten up,thrown out of their social group,and getting eaten as a result.That is the fascinating conclusion of the latest research into fish behavior by a team of Australian scientists. The research team have discovered that subordinate fish voluntarily diet to avoid challenging their larger competitors."In studying gobies we noticed that only the largest two individuals,a male and female,had breeding rights within the group," explains Marian Wong."All other group members are nonbreeding females,each being 5-10% smaller than its next largest competitor.We wanted to find out how they maintain this precise size separation." The reason for the size difference was easy to see.Once a subordinate fish grows to within 5-10% of the size of its larger competitor,it causes a fight which usually ends in the smaller goby being driven away from the group.More often than not, _ is then eaten up. It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish.Whether they did so voluntarily,by restraining how much they ate,was not clear.The research team decided to do an experiment.They tried to fatten up some of the subordinate gobies to see what happened.To their surprise,the gobies simply refused the extra food they were offered,clearly preferring to remain small and avoid fights,over having a feast. The discovery challenges the traditional scientific view of how boss individuals keep their position in a group.Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves,so keeping their competitors small. While the habits of gobies may seem a little mysterious,Dr.Wong explains that understanding the relationships between boss and subordinate animals is important to understand how hierarchical societies remain stable. The research has proved the fact that voluntary dieting is a habit far from exclusive to humans."As yet,we lack a complete understanding of how widespread the voluntary reduction of food intake is in nature," the researchers comment."Data on human dieting suggests that,while humans generally diet to improve health or increase attractiveness,rarely does it improve long-term health and males regularly prefer females that are fatter than the females' own ideal."

Heredity means all the characteristics you inherit from your parents. You get your genes from your parents. You inherit half of your genes from your mother. You inherit half of your genes from your father. Genes are a kind of code. A tree's genes tell what shape its leaves will be. A cat's genes tell what color1 its fur will be. Your genes tell what color1 your eyes will be. Your genes tell what color1 your hair will be. Everything about you comes from the code in your genes. Genes line up on strands called chromosomes in cells. Everything alive is made up of cells. Chromosomes are in the center, or nucleus, of cells. An Austrian monk named Gregor Mendel first saw inherited patterns in pea plants. He experimented with pea plants in the 1860s. One of the things, or traits , Mendel studied was what makes some pea plants tall and some short. He said that the traits must come from units of heredity passed from the parent plants. These units were called genes. In the mid-1900s, scientists discovered that genes are made of DNA. In the 1970s, scientists learned how to change DNA with genetic engineering. Scientists also learned that problems with certain genes cause diseases. Muscular dystrophy, cystic fibrosis, and hemophilia are some genetic diseases--diseases caused by problems in genes.

mmlu_stem | mmlu_stem_4903 | The research carried out by the University of Bari in Italy could help clarify hospitals who are charged with wasting money on art and decoration as it suggests a pleasant environment helps patients overcome discomfort and pain. A team headed by Professor Marina de Tommaso at the Neurophysiopathology Pain Unit asked a group of men and women to pick the 20 paintings they considered most ugly and most beautiful from a selection of 300 works by artists such as Lenoardo da Vinci and Sandro Botticelli. They were then asked to watch either the beautiful paintings, or the ugly paintings, or a blank panel while the team struck a short laser pulse at their hand, creating a sensation as if they had been hurt by a pin. The subjects rated the pain as being a third less intense while they were viewing the beautiful paintings, compared with when considering the ugly paintings or the blank panel. Electrodes measuring the brain's electrical activity also confirmed a reduced response to the pain when the subject looked at beautiful paintings. While distractions , such as music, are known to reduce pain in hospital, Prof de Tommaso says this is the first result to show that beauty plays a part. The findings, reported in New Scientist, also go a long way to show that beautiful surroundings could aid the healing process. "Hospitals have been designed to be functional, but we think that their aesthetic aspects should be taken into account too," said the neurologist. "Beauty obviously offers a distraction that ugly paintings do not. But at least there is no suggestion that ugly surroundings make the pain worse. I think these results show that more research is needed into how a beautiful environment can reduce suffering." Pictures they liked included Starry Night by Vincent Van Gogh and Botticellis' Birth of Venus. Pictures they found ugly included works by Pablo Picasso, the Italian 20th century artist Anonino Bueno and Columbian Fernando Botero. "these people were not art experts so some of the pictures they found ugly would be considered masterpieces by the art world," said Prof de Tommaso.

mmlu_stem | mmlu_stem_12054 | The globe is facing a "tidal wave" of cancer, and restrictions on alcohol and sugar need to be considered, say World Health Organization scientists. It predicts the number of cancer cases will reach 24 million a year by 2035, but half could be prevented. The WHO said there was now a "real need" to focus on cancer prevention by cutting down smoking, obesity and drinking. The World Cancer Research Fund (WCRF) said there was an "alarming" level of ignorance about diet's role in cancer. Fourteen million people a year are diagnosed with cancer, but that is predicted to increase to 19 million by 2025, 22 million by 2030 and 24 million by 2035. The developing world will bear the worst of the extra cases. Dr Chris Wild, the director of the WHO's International Agency for Research on Cancer, told the BBC: "The global cancer burden is increasing quite markedly, due predominately to the ageing of the populations and population growth. If we look at the cost of treatment of cancers, it is spiralling out of control, even for the high-income countries. Prevention is ly critical and it's been somewhat neglected." The WHO's World Cancer Report 2014 said the major sources of preventable cancer included: smoking; infections; alcohol; obesity and inactivity; radiation, both from the sun and medical scans; Air pollution and other environmental factors; delayed parenthood, having fewer children and not breastfeeding. For most countries, breast cancer is the most common cancer in women. However, cervical cancer dominates in large parts of Africa. One of the report's editors, Dr Bernard Stewart from the University of New South Wales in Australia, said prevention had a "crucial role in fighting the tidal wave of cancer which we see coming across the world". He said human behaviour was behind many cancers such as the sunbathe "until you're cooked evenly on both sides" approach in his native Australia. There was a similar argument to be had with sugar fuelling obesity, which in turn affected cancer risk. Meanwhile, a survey of 2,046 people in the UK by the WCRF suggested 49% do not know that diet increases the risk of developing cancer. A third of people said cancer was mainly due to family history, but the charity said no more than 10% of cancers were down to inherited genes. Amanda McLean, general manager for the WCRF, said: "It's very alarming to see that such a large number of people don't know that there's a lot they can do to significantly reduce their risk of getting cancer. In the UK, about a third of the most common cancers could be prevented through being a healthy weight, eating a healthy diet and being regularly physically active." "People can cut their risk of cancer by making healthy lifestyle choices, but it's important to remember that the government and society are also responsible for creating an environment that supports healthy lifestyles." What's the main reason for the increasing of cancer according to Dr Chris Wild? | [

Plastics are used today in everything. Scientists wanted to find a way to make objects made of plastic last longer. The researchers hope their new discovery can be used to make objects that are difficult or impossible to replace. The surface of plastic objects breaks over time. Very small breaks develop every time a plastic object is used. The researchers wanted to find out how to stop plastic from developing small breaks that weaken and destroy it. They found the answer in the chemical structure of plastic itself. The research team found a way to make plastic that contains very small balloons filled with monomer liquid. When the new plastic cracks, the monomer liquid is let out and flows into the crack. Thus the break is repaired. The repaired plastic has seventy-five percent of the strength of undamaged plastic. The new self-repairing plastic is not yet ready for production. But it has several possible uses. One could be in space vehicles where parts cannot be repaired or replaced.

A new study finds that Cane toads are using roads to spread across the continent. They take shelter overnight close to the opencorridors , and then hit the road each evening in their damaging way. Cane toads were brought into Australia from Hawaii in 1935 to control the spread ofbeetles that were destroying Australia's sugar cane crop. _ are now moving into new places at the speed of 30 miles a year. Toads can grow as large as dinner plates and can weigh up to 4.5 pounds. Their heads and backsides are covered with rows ofwarts . They are known to kill snakes, lizards and other animals, including pet dogs. They have no natural enemy in Australia. According to a research, toads make slower progress through thick plants than along open spaces and they hop alongside roads and fences whenever possible. Toads use long corridors that are well-suited for them to travel long distances. Another study recently found that toads haveevolved longer legs in recent years and that this is also helping them in their spread. Efforts to kill toads have been largely unsuccessful, although scientists tried their best. Another new finding suggests ways to slow down its population.

The influenza A(H7N9) virus is one smaller group among the larger group of H7 viruses. Although some H7 viruses (H7N2, H7N3 and H7N7) have sometimes been found to infect humans, no human infections with H7N9 viruses have been reported until recent reports from China. What are the main signs of human infection with influenza A(H7N9) virus? So far, most patients with this infection have had severe pneumonia . Signs include fever, cough and shortness of breath. However, information is still limited about the full area of disease that infection with influenza A(H7N9) virus might cause. How did people become infected with the influenza A(H7N9) virus? Some of the confirmed cases had connections with animals or with an animal environment. The virus has been found in a pigeon in a market in Shanghai. It is not yet known how persons became infected. The possibility of animal-to-human spread is being looked into. Is it safe to eat meat like chicken and pork products? Influenza viruses are not spread through eating well-cooked food. Because influenza viruses are made inactive by normal temperatures used for cooking (so that food reaches 70degC in all parts), it is safe to eat properly prepared and cooked meat. Diseased animals and animals that have died of diseases should not be eaten. In areas experiencing outbreaks, meat products can be safely eaten only if they are properly cooked and properly handled during food preparation. The eating of raw meat and uncooked blood-based dishes is a high-risk practice and should be discouraged. Is it safe to travel to China? The number of confirmed cases in China is very low. WHO does not advise the application of any travel measures with respect to visitors to China, nor to persons leaving China. Are Chinese products safe? There is no evidence to link the present cases with any Chinese products. WHO advises that people should not fear to trade them at this time.

The elephant herd were all rumbling :The baby elephant was even observed to be weeping and made sounds that sounded like a scream,but then the entire herd fell incredibly silent.Then they began to throw leaves and dirt over the body and broke off tree branches to cover her.They spent the next two days quietly standing over her body.They sometimes had to leave to get water or food,but they would always return. Events of elephants behaving this way around human beings are common throughout Africa. On many occasions,they have buried dead or sleeping humans or helped them when they are hurt. An old woman fell asleep under a tree.When she woke up,there was an elephant standing over her,gently touching her.She kept very still because she was frightened.As other elephants arrived,they began to scream loudly and buried her under branches.She was found the next morning by the local people,unharmed.

Ten healthy volunteers were given theobromine, codeine or placebo, a pill that contains no medicine, during the experiment. Neither the volunteers nor the researchers knew who received which pill. The researchers then measured levels of capsaicin, which is used in research to cause coughing and as a sign of how well the medicines are stopping coughs. The team found that, when the volunteers were given theobromine, the capsaicin needed to produce a cough was around a third higher than in the placebo group. When they were given codeine they needed only slightly higher levers of capsaicin to cause a cough compared with the placebo. The researchers said that theobromine worked by keeping down a nerve activity , which cause coughing. They also found that unlike some standard cough treatments, theobromine caused no side effects such as sleepiness. Which of the following would be the best title for the text? | [

mmlu_stem | mmlu_stem_5572 | Why should ear, nose, tongue and eyes be called special senses? The basic reason is that these are the channels through which we maintain contact with the surroundings. Though apparently it may feel like these are individual sensory organs, they do show some connections. Interestingly, our hearing is less sharp after we eat a heavy food. Isn't it good for a sound nap after a stomach-full meal? That does not mean we go deaf after a heavy meal, but the hearing pitch does change after that. We usually owe it to our tongue that we have taste, but do you know that unless saliva dissolves something, our tongue cannot recognize the taste of the food eaten. Taste is nothing but the food chemicals dissolved in the saliva being sensed by the taste buds present on the tongue. Try to dry off your tongue and mouth with a tissue paper and then taste something. Woman are much better smellers than man. They are born with this characteristic ability and can correctly make out the exact fragrance of the sample. We all can store almost 50,000 different scents, which are strongly tied to the memories. Pupils do not respond to light alone, but to the slightest bit of noise around too. Thus surgeons, watchmakers and those professionals who have to perform a very delicate job do prefer to have a sound-free environment. Even a small noise can enlarge their pupils, change the focus and make them see less clearly. Each and every one of us has an individualistic or characteristic smell, which is unique to us, except for the identical twins. This smell isn't very noticeable yet can be sensed even by a newborn. It may be due to this scent that the newborn recognizes the presence of his parents around. Many of us can point out the smell of our significant friends and colleagues. This is guided, to a great degree, by genetics but it is also influenced by the environment, diet and so on. This all together creates the unique chemistry that is individualistic for each person. What may happen after you have had a rich lunch? | [

mmlu_stem | mmlu_stem_8076 | The largest outbreak of the deadly disease Ebola was caused by an infected bat biting a toddler, say a group of international researchers. The 17-strong team of European and African tropical disease researchers, ecologists and anthropologists have spent three weeks investigating the outbreak of the disease in Guinea, Liberia, Ivory Coast and Nigeria. The researchers captured the bats and other creatures near the village of Meliandoua in remote eastern Guinea, where the disease began in December 2013. The boy was bitten and passed the infection on to his mother and both died within a week. The disease was then spread far and wide by the people who came to the funeral. Most of the previous outbreaks have been caused by meat from dead infected animals collected by hunters who then sell it on. Fruit bats, however, are widely eaten in rural West Africa. The team, led by epidemiologist Herr Leendertz, a disease ecologist at the Robert Koch Institute in Berlin, are expected to publish their results in a major journal soon. Herr Leendertz's team believe that an infected straw-colored fruit bat brought the disease to Guinea. The mammals are known to travel long distances and usually settle in forests near cities. Herr Leendertz said, " The evidence is not 100 percent and we can only say that it is possible. They can travel far in one night. I don't think an individual bat or colony migrated all the way from Congo or Gabon to West Africa. These big colonies are connected. There is a possibility for the virus to mix between colonies. The bats share the same fruit. It is likely not to have even been one species of bat. The virus may jump from one species to another." If the bat theory is confirmed, the locals would try to destroy the colonies, which, Herr Leendertz says, would be an ecological disaster, because bats pollinate plants and kill insects. And bat hunts would also only increase human contact with potentially infected animals. What's the main idea of this passage? | [

mmlu_stem | mmlu_stem_7428 | Rabbits are easy to raise. They are clean and quiet. They don't need a lot of room. And it costs a small amount of money to feed them, but you can get a big return. One male and two females will produce as many as fifty more rabbits in a year. That is enough to provide enough meat for a family. Rabbit meat is high in protein and low in fat. You don't have to be a farmer to raise rabbits. You can raise them in the city. Rabbit houses are easy to make with wood and wire. They don't have to be very big. But each rabbit must have its own little room in the house. This is very important. Each room should be about 75 centimeters wide, 60 centimeters high and one meter deep. Fencing is used for the sides and floor of the rabbit house. The holes in the wire fencing should be about one centimeter square. Waste from the animals will drop through the holes. This keeps the rabbit house clean and dry. Rabbits need a lot of fresh air and sunlight. Cover the sides of the rabbit house only to protect it from rain. Rabbits eat mostly grass and leaves. Hang feeding containers on the outside of the house to let the rabbits eat whenever they want. They simply pull the grass and leaves through the holes in the fence. Each room should have fresh water. The water containers should be heavy so the rabbit cannot turn them over. Or you can tie the containers to the fence. One month after mating , female rabbits give birth to about eight babies. In two months, a baby rabbit should weigh about two kilograms. This is big enough to make a meal for a small family. Rabbits are also valuable for their fur. It takes time, skill and money to prepare the fur and skin for use. If you have only a few rabbits, it probably would be best to let a tanner prepare the fur for you. Skill is also needed to remove the fur from the rabbit. _ . Many people enjoy keeping rabbits as friendly pets. And rabbit waste makes an excellent fertilizer . It can be mixed directly into the soil to improve the growth of vegetables, trees, and flowering plants. What is important if you raise rabbits? | [

mmlu_stem | mmlu_stem_9394 | Because plants cannot move or talk, most people believe that they have no feelings and that they cannot receive signals from outside. However, this may not be completely true. People who studied plants have found out that plants carry a small electrical charge . It is possible to measure this charge with a small piece of equipment called "galvanometer". The galvanometer is placed on a leaf off the plant, and it records any changes in the electrical field of the leaf. Humans have a similar field which can change when we are shocked or frightened. A man called Backster used a galvanometer for his studies of plants and was very surprised at his results. He found that if he had two or more plants in a room and he began to destroy one of them - perhaps by pulling off its leaves or by pulling it out of its pot - then the galvanometer on the leaves of the other plants showed a change in the electrical field. It seemed as if the plants were signalling a feeling of shock. This happened not only when Backster started to destroy plants, but also when he destroyed other living things such as insects . Backster said that the plants also knew if someone had destroyed a living thing some distance away, because they signalled when a man who had just cut down a tree entered the room. Another scientist, named Sauvin, achieved similar results to Backster's. He kept galvanometers fixed to his plants all the time and checked regularly to see what the plants were doing. If he was out of the office, he telephoned to find out about the signals the plants were sending. In this way, he found that the plants were sending out signals at the exact times when he felt strong pleasure or pain. In fact, Sauvin could cause a change in the electrical field of his plants over a distance of a few miles simply by thinking about them. The scientist called Sauvin _ . | [

mmlu_stem | mmlu_stem_3647 | Though the last book of the spectacular Harry Potter series was released seven years ago in 2007, the young wizard continues to be extremely popular with both kids and adults. Over the years, Harry Potter fans have been able to experience numerous aspects of the young wizard's life, right down to his favorite drink -- butter beer. Now thanks to a British hotel, they can also spend a night in the wizard's Hogwarts Castle dormitory room. The four-star Georgian Hotel in Central London, which recently opened its two wizard chambers , is ideally suited to reproducing J.K. Rowling's school of wizardry . That's because the hotel, which is still run by the descendants of the original owners, dates all the way back to 1851. It still remains its original styles inside. According to the owner of the 163-year-old Georgian Hotel, the idea originated as a way to create a kid-friendly environment in a hotel that is well-known for its Victoria Classic and Belgravia Boutique rooms. The wizard chambers that have been refinished to resemble the Hogwarts Castle dormitory rooms are furnished with everything a wizard fan could think of -- four-poster beds, stone wash basins, potion bottles, cauldrons (,), spelling books and even study tables. In order to make them appear even more magical, the hotel owners have added their own special touches that include placing a wand in the hand of the Mona Lisa painting that is in one of the chambers. As you may have guessed, these unique accommodations are not cheap. The rooms, breakfast included, cost about $350 for two people. Kids sharing the same room pay only an additional $40 each. Given that the big wizard chamber can contain up to five people, the overall cost is perfect for families that are all Harry Potter fans. Special packages include a Muggle Walking Tour that takes Harry Potter fans through the areas of the city where parts of the movies were filmed or a visit to Warner Brothers Studio, home of the Harry Potter films' sets and props . The hotel is certainly generating a lot of buzz among Harry Potter fans! If Mr Green and his wife with three children want to stay in the hotel for a night, how much should they pay? | [

Very good -- you've already mastered half the basic vocabulary of the Campbell's monkey, which lives in the forests of the Tai National Park in Ivory Coast. The adult males have six types of call, each with a specific meaning, but they can mix two or more calls together into a message with a different meaning. Having spent months recording the monkeys' calls in response to both natural and artificialstimuli , a group led by Klaus Zuberbuhler of the University of St. Andrews in Scotland argues that the Campbell's monkeys have a certain form ofsyntax . This is likely to be controversial because despite great effort to teachchimpanzees language, they showed little or no ability to combine the sounds they learned into a sentence with a larger meaning. Syntax, basic to the structure of language, uniquely belongs to humans. "Krak" is a call that warns of leopards in the neighborhood. The monkeys give it in response to real leopards and to leopard shouting broadcast by the researchers. The monkeys can vary the call by adding "-oo": "Krak-oo" seems to be a general word for hunter, but one given in a special context - when monkeys hear but don't see a hunter, or when they hear the alarm calls of another species. The "boom-boom" call invites other monkeys to come toward the male making the sound. Two booms can be combined with a series of "krak-oos", with a meaning entirely different to that of either of its single parts. "Boom boom krak-oo krak-oo krak-oo" is the monkey's version of "Timber!" - it warns of falling trees. If Zuberbuhler is correct, the Campbell's monkeys can both vary the meaning of specific calls by adding something and combine calls to make a different meaning.

mmlu_stem | mmlu_stem_10566 | I give two examples as to why intelligent life may not actually exist, though I admit that for me, or even for a physicist who devoted his or her entire life to researching and studying the universe, it's shocking to claim that completely no life exists elsewhere. Keeping that in mind, I'd just like to consider conditions elsewhere in the known universe. You really only need to look at our own solar system or the Earth at certain periods in its own history to appreciate that most places are much worse and much less suitable for life than our mild, watery globe. So far, space scientists have discovered about seventy planets outside the solar. But it appears that if you wish to have a planet suitable for life, you just have to be very lucky, and the more advanced the life is, the luckier you'll have to be. I'm by no means a space observer, but I can recognize some particularly fortunate breaks we've had on the Earth. For example: We are, to a degree, at the right distance from the perfect type of star, the one that is big enough to radiate a huge amount of energy, but not so big as to bum itself out quickly. Had our sun been ten times as huge, it would have burnt out completely after only ten million years, instead of ten billion and surely we would not exist. Too near, everything on the Earth would have boiled and withered away; any further, everything would have frozen over. The universe is a surprising place, and our existence within it is a wonder. If a long and unimaginably complex sequence of events dating back 4.6 billion years or so hadn't happened in a particular manner at a particular time --if, to take just one example, the dinosaurs hadn't been wiped out by a meteor --we might still be a few centimeters long, with whisker and a tail, and you'll be reading this in a cave somewhere.

mmlu_stem | mmlu_stem_5696 | How would you like to brush a crocodile's teeth? Or give a shark a bath? Cats are well-known for the way they keep themselves clean by licking , but other animals have their own ways to stay clean as well. And tidiness can be important for their survival. Even cockroaches have to keep their feelers clean to help them into food. Many animals in the wild, such as deer, wolves and bears, have an automatic cleaning system. Insects like to attach themselves to animals to feed on the skin or blood. These parasites can be unhealthy. But their "host" animals are constantly dropping skin and fur by a natural process. They also like to rub up against trees or rocks to comfort themselves, and this removes additional skin and fur. Along with old fur goes the dirt and parasites living in the fur. While these animals may sometimes take a bath when they enter or cross a river or lake, they don't need the water to stay clean. They don't get sweaty, because they don't have sweat glands all over their bodies the way people do. Growing new skin and fur is enough to keep them clean. Some animals and birds use dust to get clean. Chinchillas, a kind of small animal that lives in the mountains of South America, have a very fine fur. (They are raised for their fur, in fact.) If they took water baths, they might get too cold. So, instead, they roll around in fine dust, raising quite a cloud as they "bathe". The dust helps to keep their fur and skin dry. This protects them from bacteria and parasites that enjoy warm and wet places. And the fine dust doesn't stick in their fur for long. It falls off or blows away. As for lions and tigers, their rough tongues act like combs and can remove dirt and loose fur. Why is it important for them to stay clean and smooth? It helps them stay cool in very hot summer or feel warm in cold winter. It can be inferred from the passage that the way some animals stay clean_. | [

mmlu_stem | mmlu_stem_4114 | Many people have wondered what makes the oceans rise and fall on the word's beaches twice a day. Those tides are caused by the force of the Moon's gravity and the rotation of the Earth. Gravity acts on the center of any solid object. The Earth is mostly molten rock, but compared to the oceans, we can think of it as a solid object. As you know, the oceans are fluid and lie on the surface of the Earth. When the Moon is overhead, the oceans are four thousand miles closer to the Moon than the Earth's center is. Because the oceans are closer, the Moon pulls harder on the water than on the Earth. This stronger pull makes the water bunch up a little under the Moon, creating a high tide. At the same time, the oceans on the opposite side of the Earth are four thousand miles farther from the Moon than the Earth's center is. The Moon's pull on this water is weak. This water bunches up because it is "left behind"(making another high tide) as the Earth is pulled slightly towards the Moon. When the waters bunch up on these two sides of the Earth, they draw water away from the other sides of the Earth, which creates the low tides. As the Earth rotates, different parts of the land and oceans pass through the high-tide and low-tide zones. And that makes the waters on our coasts go up and down. Which of the following facts can be inferred from the passage?. | [
"Low-tide zones are near to high-tide zones.",
"The oceans of the Earth are a whole body.",
"High-tide zones are separated from low-tide zones.",

mmlu_stem | mmlu_stem_10467 | Astronaut Zhai Zhigang became the first Chinese man to walk in space on Saturday, climbing out of prefix = st1 /China's Shenzhou VII spacecraft in a technological feat that made the Chinese people excited. "I'm feeling quite well. I greet the Chinese people and the people of the world," Zhai said as he climbed out of the craft at around 16:40 Beijingtime, a historic achievement telecast live on CCTV. Tens of millions of Chinese viewers gathered before TV screens to watch the moment. Chinese President Hu Jintao and other top leaders had appeared at the BeijingAerospaceControlCenterto watch the live transmission of Zhai's spacewalk. Zhai, 42, chosen by an expert team for the first "extra-vehicular activity". unveiled a red national flag, helped by colleague Liu Boming, who also briefly popped his head out of the capsule. Zhai slowly made his way towards a test sample of solid lubricant outside the capsule, took a sample and handed it to Liu. Zhai safely returned inside the craft after about 20 minutes. The walk marked the high point of China's third manned space journey, which has received widespread media coverage. Zhai wore a$4.4 million Chinese-made suit weighing 120kg. Liu wore a Russian-made one and acted as a back-up. The third crew member, Jing Haipeng, monitored the ship from inside the re-entry module. The risky manoeuvre is a step towards China's longer-term goal of assembling a space lab and then a larger space station, analysts said. "On this flight, Chinese people's footprints will be left in space for the first time," said a commentary by the Xinhua News Agency. The astronauts embarked on their walk after receiving a clean bill of health from doctors on the ground at mission control in Beijing, Xinhua said. Zhai's suit has 10 layers and takes up to 15 hours to assemble and put on. China's first manned spaceflight was in 2003. A second, two-manned flight followed in 2005.

mmlu_stem | mmlu_stem_4694 | As we have seen, the focus of medical care in our society has been shifting from curing disease to preventing disease--especially in terms of changing our many unhealthy behaviors, such as poor eating habits, smoking, and failure to exercise. The line of thought involved in this shift can be pursued further. Imagine a person who is about the right weight, but does not eat very nutritious foods, who feels OK but exercises only occasionally, who goes to work every day, but is not an outstanding worker, who drinks a few beers at home most nights but does not drive while drunk, and who has no chest pains or abnormal blood counts, but sleeps a lot and often feels tired. This person is not ill. He may not even be at risk for any particular disease. But we can imagine that this person could be a lot healthier. The field of medicine has not traditionally distinguished between someone who is merely "not ill" and someone who is in excellent health and pays attention to the body's special needs. Both types have simply been called "well". In recent years, however, some health specialists have begun to apply the terms "well" and "wellness" only to those who are actively striving to maintain and improve their health. People who are well are concerned with nutrition and exercise, and they make a point of monitoring their body's condition. Most important, perhaps, people who are well take active responsibility for all matters related to their health. Even people who have a physical disease or handicap may be "well" in this new sense, if they make an effort to maintain the best possible health they can in the face of their physical limitations. "Wellness" may perhaps best be viewed not as a state that people can achieve, but as an ideal that people can strive for. People who are well are likely to be better able to resist disease and to fight disease when it strikes. And by focusing attention on healthy ways of living, the concept of wellness can have a beneficial impact on the ways in which people face the challenges of daily life.

mmlu_stem | mmlu_stem_11239 | Tiny monitoring devices have become an increasingly common way for scientists to study elusive animals that are difficult to track on a day-to-day basis. However, now it seems that smart. seals have caught on to the trick and are using it to their advantage to catch fish! To find out if that is true, a team of researchers from the University of St. Andrews in Scotland selected a group often young grey seals that had neither encountered the ocean nor been exposed to any kind of acoustic tags. The researchers then placed the seals one at a time, inside a pool that contained 20 foraging boxes, only two of which housed fish -- one with tags and the other without. Each seal was allowed to explore the boxes twenty separate times. In order to ensure that mammal was not depending on its memory, the fish were moved to different boxes each time. At first, there was no difference in the amount of time it took the seals to discover the tagged and untagged fish. However, after they had been in the pool a few times, they started locating the tagged fish much faster. To confirm that this indeed was the case, there searchers conducted a second experiment using two boxes -- one with pieces of fish and the other with just acoustic tags. Sure enough, the seals were all attracted to the one that was sending out signals. While this experiment involved only seals, the researchers believe that other marine mammals may also be using the information to catch prey. Sadly, predators like sharks that have been tagged by scientists may be negatively affected, as pings they emit could warn their prey of their presence. Besides potentially messing up nature's food chain, the "dinner bell" effect of the acoustic tags could also mean that the conclusions reached by previous fish studies may not be correct. Now that the secret is out, scientists will have to come up with another way to conduct their studies -- one that is not detectable by the crafty marine animals. What is implied about the ten young grey seals? | [

It is a website in which a person or a group can place news, personal thoughts, text, photos, video or audio files, or links upon which visitors can comment. A blog lets you post on the Internet without having to know web design or be technical. You are given an environment to make dated entries on the topic of your choice which are "published", so other people can read them. Authoring a blog, maintaining a blog or adding an article to an existing blog is called "blogging". Blogging has revolutionized Internet publishing in the last several years because it gives everyone with Internet access the opportunity to become an online writer. Objects, such as "text and photos" in a blog can be called "blog posts", "posts", or "entries". The person who posts these entries is called a "blogger". Now, somewhere around the world, a blog is created almost every 6 seconds. Because it's great potential, Bill Gates views it as important as e-mail, BBS, and MSN.

mmlu_stem | mmlu_stem_5809 | Many people believe the glare from snow causes snow-blindness. Yet, dark glasses or not , they find themselves suffering from headaches and watering eyes, and even snow-blindness, when exposed to several hours of "snow light". The United States Army has now determined that glare from snow does not cause snow-blindness in troops in a snow-covered country. Rather, a man's eyes frequently find nothing to focus on in a broad expanse of barren snow-covered terrain . So his gaze continually shifts and jumps back and forth over the entire landscape in search of something to look at. Finding nothing, hour after hour, the eyes never stop searching and the eyeballs become sore and the eye muscles ache. Nature eases this irritation by producing more fluid which covers the eyeball. The fluid covers the eyeball in increasing quantity until vision blurs , then is obscured , and the result is total, even though temporary, snow-blindness. Experiments led the Army to a simple method of overcoming this problem. Scouts ahead of a main body of troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape. Even the scouts themselves throw lightweight, dark colored objects ahead on which they too can focus. The men following can then see something. Their gaze is arrested. Their eyes focus on a bush and having found something to see, stop scouring the snow-blanketed landscape. By focusing their attention on one object at a time, the men can cross the snow without becoming hopelessly snow-blind or lost. In this way the problem of crossing a solid white terrain is overcome.

The dogfish shark, however, is less than twenty centimeters in length. A shark has an extremely good sense of smell. It can find small amounts of matters in water, such as blood, body liquids and chemicals produced by animals. These powerful senses help sharks find their food. Sharks eat fish, other sharks, and plants that live in the ocean. Sharks grow slowly. About forty percent of all sharks lay eggs. The others give birth to live young. Some sharks carry their young inside their bodies as humans do. Some sharks are not able to reproduce until they are twenty years old. Most reproduce only every two years. And they give birth to fewer than ten young sharks. For this reason, over-fishing of sharks is of special danger to the future of the animal. Sharks are important for the world's oceans. They eat injured and diseased fish. Their hunting activities mean that the numbers of other fish in ocean waters do not become too large. This protects the plants and other forms of life that exist in the oceans. People hunt sharks for sport, food, medicine and their skin. Experts say the international market for some kinds of sharks has increased because many parts of a shark are valuable.Collectors pay thousands of dollars for the jaws of a shark. Shark liver oil is a popular source of Vitamin A. The skin of a shark can be used like leather. In Asia, people enjoy a kind of soup made from shark fins. Experts say a fisherman can earn a lot of money for even one kilogram of shark fins. Sharks are among the oldest animals on Earth, but some sharks are in danger of disappearing from Earth.

Larger male chimps drop from the trees to face the threat while the others climb to safety. Then the dogs' young human masters appear. One mother chimp with a tiny baby tries to run. The dogs attack and separate them. The two teenage boys quickly catch the baby chimp. But they don't act out of sympathy --- they save the baby so they can sell it. After the teenagers return to their hometown, they visit a man who is said to be very interested in chimps. When they ask the man, Johnny Kante, if he wants to buy the baby, he replies, "That's not what we do." Kante is a member of a scientific team. Although Kante is angry with the teens for capturing the chimp, he hides his anger and persuades them to take him to the baby chimp. Unsure of what to do next upon seeing the chimp, Kante calls Jill Pruetz, the head of the chimp research team. "I'm really worried," says Pruetz, doubtful that the mother is still alive. But knowing that wild chimps sometimes adopt orphans , Kante and pruetz decide they must try to return the baby chimp to its wild community. Kante pays another visit to the teenagers. After he explains how much trouble they are in, because chimps are an endangered species, he requests they should give him the frightened baby without payment. They agree. Kante takes the baby chimp to his home and feeds her milk from a bottle whenever she cries. The next morning, Pruetz and Kante leave the baby with another team member and begin their search for the wild chimps. Pruetz quickly finds the group in the woods. She recognizes the female that is without her child. Pruetz is so excited that she runs the entire mile back to bring the baby chimp to the tree where the chimps are hanging out. The researchers place the baby on the ground near the tree and back away. Almost immediately, a male chimp drops to the ground and stares at the baby curiously. He carries her back to where the mother is waiting. Pruetz still can't believe how fortunate they were to have reunited the mother and child. "Surprising is the only word I can think of," she says.

mmlu_stem | mmlu_stem_5887 | Wild animals are our friends, but many of them are getting fewer and fewer. We should try to protect them. The four animals below are now in danger. Tibetan Antelopes Tibetan antelopes are medium-sized animals. They mainly feed on grass. They are usually found in groups of about 20. They are killed for their wool, which is warm, soft and fine and can be made into expensive clothes. Although people can get the wool without killing the animals, people simply kill them before taking the wool. The number of them is dropping year by year. There are less than 75,000 Tibetan antelopes left in the world, down from a million 50 years ago. Golden Monkeys Golden monkeys are mainly found in Sichuan, Gansu, Shanxi provinces and Shengnongjia mountainous area of Hubei Province. Golden monkeys have golden-orange fur. They move around in the daytime, usually in groups of as many as 100 to 200 heads, or 20 to 30 heads. They feed on fruits and young leaves of bamboos. But people are destroying the environment where they live. Trees and bamboos are disappearing, so golden monkeys have less and less to eat. Elephans ks5u Elephants are very big and strong. They are bigger than any other animals on land. They are grey and have long trunks and tusks. They have poor eyesight, but very good hearing and smell. They can lift heavy things and break down branches with their trunks. Elephants are very friendly towards each other and towards their neighbours. Normally, they live in a group for many years.

mmlu_stem | mmlu_stem_12056 | Once in a blue moon, there is one on New Year's Eve. Revelers ringing in 2010 will be treated to a so-called blue moon. According to popular definition, a blue moon is the second full moon in a month. But don't expect it to be blue - the name has nothing to do with the color of our closest celestial neighbor. A full moon occurred on December 2. It will appear again on Thursday in time for the New Year's countdown. The New Year's Eve blue moon will be visible in the United States, Canada, Europe, South America and Africa. For partygoers in Australia and Asia, the full moon does not show up until New Year's Day, making January a blue moon month for them. A full moon occurs every 29.5 days, and most years have 12. On average, an extra full moon in a month - a blue moon - occurs every 2.5 years. The last time there was a lunar double take was in May 2007. New Year's Eve blue moons are rarer, occurring every 19 years. The last time was in 1990; the next one won't come again until 2028. "Blue moons have no astronomical significance," said Greg Laughlin, an astronomer at the University of California. "`Blue moon' is just a name in the same sense as a `hunter's moon'(a full moon in octorber) or a `harvest moon,'" Laughlin said in an e-mail. The popular definition of blue moon came about after a writer for Sky & Telescope magazine in 1946 misinterpreted the Maine Farmer's Almanac and labeled a blue moon as the second full moon in a month. In fact, the almanac defined a blue moon as the third full moon in a season with four full moons. What's the color of blue moon? | [

mmlu_stem | mmlu_stem_5270 | With petroleum reserves decreasing,the search is on to replace gas with a cleaner,greener alternative.Though much eco-talk has centered on biofuels from corn and soybeans,the biofuel that looks more likely to replace petroleum comes from a most unlikely source:algae . Algae,like corn,soybeans,and other crops,grow via photosynthesis and can be processed into fuel oil.However,they _ 30 times more energy than land crops such as soybeans,according to the U.S.Department of Energy.Many algae species also can grow in saltwater and polluted water-while corn and soy require arable land and fresh water that will be in short supply as the world's population balloons. "If you replaced all the diesel in the U.S.with soy biodiesel,it would take half the land mass of the U.S.to grow those soybeans,"says Matt Caspari,chief executive of Aurora Biofuels,a Berkeley,Calif.-based private firm that specializes in algae oil technology.On the other hand,the Energy Department says that if algae fuel replaced all the petroleum fuel in the United States,it would require 15,000 square miles,which is a few thousand miles larger that Maryland (12,407 square miles),the 42nd state in land area. Another bonus:Because algae can be grown just about anywhere in a closed space,they 're being tested at several power plants across the nation as a carbon absorber.Smokestack emissions can be pumped directly into the ponds,feeding the algae while keeping greenhouse gases out of the atmosphere. Although processing technology for algae fuel--also known as "oilgae" in some environmentalist circles--is improving,it's still years away from reaching your local gas pump."It's just a question of cost,because no large-scale facilities have been built yet," Caspari says.

mmlu_stem | mmlu_stem_6200 | At first sight the planet Mars does not appear very welcoming to any kind of life. It has very little oxygen and water, the temperature at night is below 50 degrees and winds of 100 miles (161 kilometers)per hour cause severe dust storms. However, the surface of the planet seems to show that water flowed across it at some time in the past, and it is believed that there would be enough ice at the poles to cover the planet with water if it melted. Although there is no life on the Mars now, some scientists think there may have been some form of life a long time ago. At that time, the planet had active volcanoes ; the atmosphere was thicker and warmer; and there was water. In fact, in some ways the Mars may have been similar to the Earth, where life exists. Some people believe that the Mars could support life in the future if the right conditions were produced. The first step would be to warm the planet using certain gases which trap the Sun's heat in the planet's atmosphere. With warmth, water and carbon dioxide , simple plants could begin to grow. These plants could slowly make the Mars fit to live on. It is judged that the whole process might take between 100, 000 and 200, 000 years.

mmlu_stem | mmlu_stem_14763 | Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings. The noise that affects sea animals comes from a number of human activities. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves. Decibels measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land caused pain to human ears. In water, a decibel level of one hundred and ninety-five would have the same effect. Some scientists have planned to set a noise limit of one hundred and twenty decibels in oceans. They have found that noises at that level can frighten and confuse whales. A team of American and Canadian scientists discovered that loud noises can seriously hurt some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales' ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected. Many researchers whose work depends on ocean sounds disagree to a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research. Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists suspect that noise is a greater danger than they believed. They want to stop noises from harming creatures in the ocean. We can know from the passage that many scientists think that the noise limit of one hundred twenty decibels would _ . | [

mmlu_stem | mmlu_stem_5128 | I'm sure many of you have seen Star Wars, Jurassic Park, Multiplicity, or many of the other movies that describe cloning. Most of what you see in these movies is false. What you don't know is that cloning could be dangerous, to the clone and to our society as a whole. I think human cloning is wrong mainly for four reasons. What about identity? Humans are promised the right to their own personalities. What would happen if we ignore those rights by giving them someone else's genetic identity? True, Cloning may prevent people from possessing their identities. Also, these is a large power struggle here. Cloning means a degree of power and controls over another person's physical identity and that ignores their rights and their only personalities. The person doing the cloning would have more power than any parent would have. Cloning would also deal with killing embryos . You might not have known, but Dolly, the sheep that was cloned in 1996, was one of over 200 sheep embryos and hers was the only embryo that survived. The rest died or were thrown away. Imagine if the failure rate was that high when we started to clone humans. cloning means running the risk of wasting too much effort Cloning someone, at this present time, would be extremely dangerous to the birth mother and the clone. In studies done on cows, 4 out of 12 birth mothers died. There is a very high failure rate, which is shown in the cloning of Dolly. Even if you had a few good embryos, failures have been noticeable in animal tests. So, should we work ahead in the world of cloning? I say no. the risks are greater than the benefits. It's dangerous to the clone and to the birth mother. We would be killing human lives in the process. It would also be a violation of the clone's right to its own genetic identity and personality.

mmlu_stem | mmlu_stem_9918 | Carbon monoxide poisoning kills and injures many people and animals around the world. The gas has been a problem since people first began burning fuels to cook food or to create heat. It is a problem in all parts of the world that experience cold weather. Carbon monoxide is called the silent killer because people do not know it is in the air. The gas has no color1. It has no taste. It has no smell. It does not cause burning eyes. And it does not cause people to cough. But it is very deadly. It robs the body of its ability to use oxygen. Carbon monoxide decreases the ability of the blood to carry oxygen to body tissues. It does this by linking with the blood. When the gas links with the blood, the blood is no longer able to carry oxygen to the tissues that need it. Damage to the body can begin very quickly from large amounts of carbon monoxide. How quickly this happens depends on the length of time a person is breathing the gas and the amount of the gas he or she breathes in. Carbon monoxide poisoning has warning signs. But people have to be awake to recognize them. Small amounts of the gas will cause a person's head to hurt. He or she may begin to feel tired. The person may feel sick. The room may appear to be turning around. The person may have trouble thinking clearly. People develop severe head pain as the amount of gas continues to enter their blood. They will begin to feel very tired and sleepy. They may have terrible stomach pains. Medical experts say carbon monoxide affects people differently. For example, a small child will experience health problems or die much quicker than an adult will. The general health of the person or his or her age can also be important. An older adult with health problems may suffer the effects of carbon monoxide more quickly than a younger person with no health problems. People with heart disease may suffer chest pains. They may begin to have trouble breathing. How does carbon monoxide harm people? | [

And how far away is it? Recently, the Kepler spacecraft found "22b", a planet about six hundred light years away. It is the first planet in a "habitable zone" outside the solar system. That means the planet orbits a star like our sun, but it is not too close to it, nor too far away. Because of this position, Kepler-22b might have water, one of the main things needed for life. The newly-discovered planet is about two and a half times larger than the Earth. It is closer to its star than we are to the Sun, but 22b's sun is smaller than ours, and doesnt produce as much heat. Scientific instruments show the new planet could be made of gases, rocks or some kinds of liquids. The Kepler spacecraft was named in honor of Johannes Kepler, the seventeenth century German astronomer. It was designed to examine a small part of the Milky Way galaxy and search for places like the Earth. It was made to inspect over 150,000 stars and measure how bright they are. It looks to see if a star's brightness gets less over a short time. If a planet passes between Kepler and the star, it blocks out part of the light. That is what suggested to scientists that there is at least one planet orbiting the star. The instruments on Kepler show the new planet as a small, black dot moving across its sun. An important part of the Kepler experiment is on the Earth. After the spacecraft gathers information, scientists use the telescopes on the ground. Scientists have found over 2,300 new planets since Kepler was launched. Most are much larger, but it is the new planet's distance from its star that is important. For life to possibly exist there, the planet's temperature must not be too hot or too cold. What can we learn about Kepler-22b? | [

However, some smokers may have to seek help from medication in order to kick the habit. What medication actually does is to reduce the wish to smoke. Some of the medication must be taken with a doctor's guidance. The five most common medications to stop smoking are Bupropion SR, nicotine gum, nicotine inhalers, nicotine nasal spray and nicotine patches. People can buy nicotine gum and nicotine patches in chemists. However, the other medications require a prescription. Zyban tablets have been found to be highly effective in curing people of smoking addiction. The tablet needs to be taken whole, without crushing it, as crushing can lead to side effects. It can be bought on the prescription of a doctor. Nicotine patches are filled with nicotine and they are applied to the skin. The skin takes in the nicotine and carries it to the blood stream. The amount of nicotine in these patches is quite limited, not enough to lead to addiction. But you shouldn't take them for dinner. In fact, millions of people have benefited from these nicotine patches. Nicotine gum is supposed to be a safer choice. It is used in such a way that it comes into contact with the blood vessels in the mouth and then releases the nicotine. The nicotine should not go through the stomach; otherwise, it may cause certain side effects. These different types of medications have to be taken quite carefully.

Researchers show scientific evidence that a dog's extraordinary smelling ability can distinguish people with both early and late stage lung and breast cancers from healthy people. Researchers first discovered this in the case report of a dog warning its owner to the presence of a melanoma by constantly sniffing the skin lesion . Later studies published in major medical magazines proved the ability of trained dogs to detect both melanomas and bladder cancers. The new study is the first to test whether dogs can detect cancers only by sniffing the breath of cancer patients. In this study, five household dogs were trained within a short 3-week period to detect lung or breast cancer by sniffing the breath of cancer patients. The experiment consisted of 86 cancer patients (55 with lung cancer and 31 with breast cancer) and 83 healthy people. All cancer patients had recently been diagnosed with cancer and had not yet undergone any chemotherapy treatment . The dogs were presented with breath samples from the cancer patients and the healthy ones, captured in a special tube. Dogs were trained to give a positive identification of a cancer patient by sitting or lying down directly in front of a test station containing a cancer patient sample, while ignoring healthy samples. The results of the study showed that dogs can detect breast and lung cancer between 88% and 97%. Moreover, the study also proved that the trained dogs could even detect the early stages of lung cancer, as well as early breast cancer. The researchers concluded that breath analysis might become a potential of cancer diagnosis. The research found that dogs could help detect cancers by _ . | [

mmlu_stem | mmlu_stem_6329 | Password strength has been a topic about the Internet lately. I have seen lots of clever methods for generating and remembering strong passwords. Some are better than others, but in my opinion , none are adequate . Here's the problem : it doesn't matter how strong your passwords are if you use the same one on multiple sites. All it takes is for a site to get hacked , like Gawker media, or even Sony did , and now your super-strong password has been stolen , and every site on which you used that password has been accessed . So, the bottom line is that no matter how strong your passwords are , and no matter what clever tricks you use to help you remember them , if you surf the Internet often , the only truly secure password system is what you need . Enter LastPass. It's not the only password manager out there, but I like it the best. You create ONE strong password that you have to memorize and use it to access your LastPass database . The LastPass database is stored online, on LastPass's servers. LastPass recognizes the site you're on and automatically logs you in (after , optionally , asking you to re-enter your master password). LastPass also has automatic form fill and automatic password generation. This means that you can have a different , unique , very strong password for every site you log into , but you only have to remember one master password . It's the best of both worlds. One argument against LastPass is that if their database is attacked , then all of your sites are in danger, and that's true, but given that their entire line of work is keeping that information safe , I'm willing to take that chance. The alternative is rolling dice or picking phrase to create passwords, writing all of them down on a piece of paper or something , and then having to manually type them in when I go to a site . A terrible mess. There is a free version of LastPass , with additional features unlocked if you pay $ 12 for a year's subscription . ----Joshua Bardwell Joshua Bardwell writes the passage to _ . | [
