mmlu_stem | mmlu_stem_5194 | 8-year-old Mario spent one day selling lemonade in New Jersey. But he didn't do it for spending money. "The people in the hospital need more medicine," Mario said. Mario's lemonade stand raised money after a group called Alex's Lemonade Stand, which is an organization that raises money for research on cancers that affect kids.Their research might one day lead to a cure.The organization is named for Alexandra Scott, a girl who died of cancer eight years ago when she was eight years old.Alex' s Lemonade Stand actually began four years earlier before she died.That's when she announced that she wanted to sell lemonade to raise money for a cancer cure for all kids. This year, thousands of kids across the country are selling lemonade to raise money for Alex's foundation.In Maryland, a group of kids at the Children's Guild held a fund - raiser for Alex in April. And in Florida, Harrison began raise money for Alex's Lemonade Stand last year, when he was seven.This year, he raised more than $ 500 dollars.Harrison hoped it could help kids by scientists finding a cure.He also dreamed of finding a cure himself."When I grow up, I'm going to invent these little 'nano-bots' that can swallow cancer.They can fight cancer for you with their little mini - lasers and stuff," Harrison said. "To see how that one simple idea grew into this national foundation, all of these supporters coming out in Alex's memory , it' s really special for me.It' s against my expectation,"said Liz Scott, Alex' s mother. What made Mario's lemonade stand even more special and amazing than most is that he, too, has cancer--six brain tumors.But Mario is not giving up.And he is determined to help other kids like him--in memory of Alex." He lost a lot of friends who were in the hospital,"said Mario's mom, Anna."And he wants to be sure that he doesn't lose anymore." What do we know about Harrison according to the passage? | [

mmlu_stem | mmlu_stem_8285 | It is well-known that twins are closer to each other than most brothers and sisters ---- after all, they probably spend more time with each other. Parents of twins often notice that they develop special ways of communicating: they invent their own words and one can often finish the other's sentence. In exceptional circumstances, this closeness becomes more extreme: they invent a whole language of their own, as in the case of Grace and Virginia Kennedy from Georgia in the USA, who communicated so successfully in their own special language that they did not speak any English at all until after they started school. However, these special relationships are the result of lives spent almost entirely in each other's company. What happens when twins do not grow up together, when they are separated at birth for some reason? Are they just like any other strangers, or are there still special similarities between them? Professor Tom Bouchard, of the University of Minnesota, set out to find the answer to this question. He traced sixteen pairs of twins, who were adopted by different families when they were babies, and often brought up in very different circumstances. Each twin was then interviewed about every small detail of their life. The results of this research make a surprising reading. Many of the twins were found to have the same hobbies, many have suffered the same illnesses, and some have even had the same type of accident at the same point in their lives. One pair of middle-aged women arrived for their first meeting in similar dresses, another pair were wearing similar jewellery. The most incredible similarities are to be found in the case of Jim Springer and Jim Lewis from Ohio in the USA. The story of the 'Jim Twins' made headline news across USA. Born to an immigrant woman in 1939, and adopted by different families at birth, both babies were named Jim by their new parents. But what can be the explanation for these remarkable similarities? Is it all pure coincidence, or is the explanation in some way genetic? Research into the lives of twins is forcing some experts to admit that our personalities may be at least partly due to 'nature'. On the other hand, analysts are also anxious to emphasise that incredible coincidences do happen all the time, not just in the lives of twins. The purpose of Tom Bouchard's study is to find _ . | [

mmlu_stem | mmlu_stem_10435 | We may not be aware of it, but ordinary family homes in the U.S. and the rest of the world are not energy-efficient. Most of their energy goes to heating and cooling, and a lot of it is wasted, as warm air and cool air escape through fireplace chimneys and thin or poorly fitting windows and doors. A passive house loses almost none."Imagine a thermos ,"said housing developer Brendan O'Neill."You have insulation everywhere, and it's basically completely sealed. And so the idea is to build a house like a thermos. So the windows are sealed. There's insulation completely surrounding the building. We make it as sealed as possible." A 147-square-meter passive house, presented by O'Neill Development Corp. as a demonstration unit just outside Washington, was brought to the site in two boxes."Once it's set and put together, it takes about four weeks to complete the outside construction, to put down carpets,"O'Neill said."If everything is set in place, you put a house like this together in about four months."The total cost of building it was $325,000, or about 17 percent more than constructing an ordinary house. But its utility bill is only around $20 monthly, or one-tenth the amount for the average house of the same size. While passive houses have been around for a long time, the idea has never taken root in the U.S. There was no driving force to push it. However, David Peabody, an architect who designs passive houses said,"I think climate change is now becoming a larger issue. And I think building standards are catching on to that. So people are becoming more aware of energy."Peabody said the cost of building passive houses could come down."What really makes sense for truly affordable housing,"he said,"is to build multi-storey buildings." What is the feature of a passive house? | [

mmlu_stem | mmlu_stem_8486 | Have you ever wondered why birds sing? Maybe you thought that they were just happy.After all,you probably sing or whistle when you are happy. Some scientists believe that birds do sing some of the time just because they are happy.However,they sing most of the time for a very different reason.Their singing is actually a warning to other birds to stay out of their territory Do you know what a "territory" is? A territory is an area that an animal,usually the male,claims as its own.Only he and his family are welcome there.No other families 0f the same species are welcome.Your yard and house are your territory where only your family and friends are welcome.If a stranger should enter your territory and threaten you,you might shout.Probably this would be enough to frighten him away. If so,you have actually scared the stranger away without having to fight him.A bird does the same thing. But he expects an outsider almost any time,especially at nesting season.So he is screaming all the time,whether he can see an outsider or not This screaming is what we call a bird's song,and it is usually enough to keep an outsider away. Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs. You can see that birds have a language all their own.Most of it has to do with attracting mates and setting up territories. What is a bird's "territory"? | [

To make the runner's body work, harder training is quite necessary. A runner should start to prepare for a marathon at least three months before. Preparation may have races, many hours of running at different speeds and changes in diet . During the training time the runner must eat a fit diet. The diet should have lots of things needed in training the players. In the early days of training, runners run 80km per week. The running is increased every two or three weeks and at least two long runs per week are needed. Two weeks before the marathon, the training programme becomes less, from 100km per week down to 60km and then to 30km in the final week. On the last two days they may not run at all. Breakfast should be eaten at least three hours before the race. Easily digested food such as cereal , toast and scrambled egg is best, with as much fluid as possible. Runners should drink water about half an hour before the race to keep up the body fluid. Players must have _ in order to run better in a marathon. | [

mmlu_stem | mmlu_stem_2331 | In many sports, physical contact is part of the game. But when athletes hit their heads, the hit can cause concussions . Concussions have long been a concern for professional athletes, but they've become more common among young players too. Between 2001 and 2009, the number of kids under 19 visiting doctors for concussions each year increased by 62 percent. Engineers are developing new helmets , and new rules are limiting physical contact in some sports. But are these efforts enough to protect kids' brains? Concussions can happen during many types of activities. But sports like football and soccer are especially risky. When you run or jump, your body is moving at an increased speed. A sudden hit causes you to move faster in a different direction. "It's like when you're in a bus and it makes a sudden stop," says Dr. Kevin Crutchfield, an expert at a sports concussion center in Baltimore, Maryland. "You hit the inside of the bus." This hit damages the brain. It affects the way the brain functions. So some sports require athletes to wear helmets. Helmets help reduce the force of a hit. The hard outer shell spreads the force of larger area. Inside a helmet, a plastic or air-filled lining also helps soften the blow. Steve Rowson is an engineer at Virginia Tech. In his lab, he tests how helmets hold up against different types of hits. No helmet can prevent concussions completely, says Rowson. But he's found that when wearing a newer football helmet, the player's head doesn't gain speed as much after a hit. That lowers the risk of concussions. Many youth sports teams have set limits on physical contact to reduce the risk of concussions. In soccer, most concussions happen as a result of headers--shots or passes made with the head. That's why many people think kids shouldn't head the ball until high school. These efforts should help, says Crutchfield. But the best way to prevent long-term brain injuries, he says, is to stop playing immediately if you suffer concussion. "Protect yourself today so you can play again tomorrow."

mmlu_stem | mmlu_stem_4509 | A "match of the century" between human champion of the Chinese board game Go and Google's computer program kicked off in Seoul on Wednesday, which drew great attention. The first game of the five-game match started at about 1 p.m.local time (0400 GMT) at Four Seasons Hotel in central Seoul.It will run through next Tuesday to determine the winner between South Korean Lee Sedol, the world Go champion in the past 10 years, and AlphaGo, developed by Google's London-based subsidiary DeepMind. The match of the century drew great attention from news organizations, Go fans and the general public across the world as well as in South Korea as it is seen as a representative match between humans and artificial intelligence (AI). The Korea Baduk Association, a body for South Korean Go professionals, had received advance applications for an explanatory event of the match, but the limit of 60 seats had already surpassed. South Korea's public broadcaster KBS plans to broadcast live the match from 12:40 to 5 p.m., extending its initial plan to air it for two hours from 3 p.m.due to great interests from the general public.It is unusual for the public broadcaster to broadcast live the Go game for more than four hours. Cable channel TV Chosun will broadcast the match's development every 10 minutes on Wednesday and Thursday, while planning to air live the whole matches on Saturday and Sunday. The match is being aired live through YouTube around the world, while various Internet websites and TVs are broadcasting the landmark match. Hundreds of journalists from around the world gathered at the venue to report on the match between Lee and AlphaGo. AlphaGo took the world by surprise as it defeated European Go champion Fan Hui in October last year.Some experts had predicted it would take decades of years for AI to defeat humans at the ancient Chinese board game. Go, which originated in China more than 2,500 years ago, has been viewed as a grand challenge for AI due to its complexity and intuitive nature.It involves two players, who take turns putting markers on a grid-shaped board to gain more areas on it.One can occupy the markers of the opponent by surrounding the pieces of the other. Why did the match draw so much attention in the world? | [

mmlu_stem | mmlu_stem_10297 | Every human being has a unique arrangement of the skin on his fingers and this arrangement is unchangeable. Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case. The ridge structure on a person's fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one which bears a reproduction of the original pattern. It is only when the inner skin is injured that the arrangement will be destroyed. Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take. Finger-prints can be made very easily with printer's ink. They can be recorded easily. With special methods, identification can be achieved successfully within a short time. Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. His finger-prints can prove who he is even if his appearance has been changed by age or accident. When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye. Special techniques are used to "develop" them. Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained. Some criminals remove their own finger-prints by _ . | [

mmlu_stem | mmlu_stem_7194 | Miami Beach is a top destination for vacationers from around the world --not to mention a location for sea turtles laying eggs. For years, female sea turtles have returned to the beaches where they were born to build nests for their next generation. As Miami Beach continues to develop; wildlife officials and volunteers are making sure the beach remains a welcoming place for these endangered animals. The sea turtle patrol starts his day at sunrise. "The reason we need to get out at first light is to make sure we see the tracks before anybody else gets out here, Bill Ahern says, "Something that weighs 350 pounds is going to leave evidence." Bill Ahern directs the sea turtle program in Miami-Dade county. His team monitors and marks nests left by sea turtles who lay eggs in the sand and then return to the sea. The patrols also work with beach residents to keep track of new nests and possible threats to existing ones. Nearly 65,000 turtles nested on Florida's Atlantic coast last year. A tiny part comes to Miami Beach where they face many risks. Tough laws have been passed to punishpoachers . And bright lights from nearby buildings can confuse newly born turtles, attracting them onto roads instead of into the ocean. "I recall in the mid-1960s, me and my beach buddies(policemen) would pick up hatchlings from the road and put them back in the water," he recalls .To avoid that problem, city officials have imposed limits on coastal lighting. Although most sea turtles hatch on their own, coming out at night, some have a harder time. In the future, the Sea Turtles Program hopes to do away with the hatchery. Educating beach-goers is a step in that direction. Each week, people are invited to see a release of newly born turtles recovered from nests. The experience helps sunbathers understand the role of the beach in the turtle's life cycle. "Only a part of the newly hatched turtles will escape predators and man-made dangers in their first year." Their instincts are so sharp ," Ahern says, "I'll face a turtle to the west, and then watch him, he turns right around ,facing the ocean. " What is the main idea of this passage? | [

mmlu_stem | mmlu_stem_6019 | Scientists are debating how to limit their newly-discovered power to change genetic structure. Scientists already modify the genes of farm animals and agricultural plants to make them more productive or stronger. But now they can also change genes in wild animals and plants. These genes would continue into later generations. For example, it may be possible for scientists to remove from existence the kind of mosquitoes that carry the Zika virus. They might also be able to permanently remove species of plants and animals that are destructive to other species. In a report published last week, the U. S. National Academies of Sciences, Engineering and Medicine (NAS) said it supports continued research on this kind of gene control. But it warned that it is not possible to know what will happen when these changed plants and animals are released into the wild. Sixteen biologists, ethicists and policymakers are on an NAS committee that is examining the issue. They say that there is value to the new technology. But, they say, there is not enough evidence to support the release of modified organisms from the laboratory into nature. Many people would support stopping mosquitoes and rats from carrying diseases. But scientists say we must understand the possible scientific, ethical, legal and social results of such action before we decide whether to take it. Gene modification is spread through reproduction . Changed genes will continue to spread as long as an animal or plant continues to reproduce. They cannot be limited to a farm or kept within a country's borders. Scientists are wondering what may happen if a modified organism mates with another species. They are not yet sure how the modified genes would affect the other species. It is possible that those genes could harm those creatures or even lead to their disappearance from our planet. As for genetically changed wild animals and plants ,what are scientists worried about? | [

mmlu_stem | mmlu_stem_11898 | Mandara seemed to know something big was about to happen. So she let out a yell, caught hold of her 2-year-old daughter Kibibi and climbed up into a tree. She lives at the National Zoo in Washington, D.C. And on Tuesday, August 23rd, witnesses say she seemed to sense the big earthquake that shook much of the East Coast before any humans knew what was going on. And she's not the only one. In the moments before the quake, an orangutan let out a loud call and then climbed to the top of her shelter. "It's very different from their normal call," said Brandie Smith, the zookeeper. "The lemurs (monkey-like animals of Madagascar) will sound an alarm call if they see or hear something highly unusual." But you can't see or hear an earthquake 15 minutes before it happens, can you? Maybe you can -- if you're an animal. "Animals can hear above and below our range of hearing," said Brandie Smith. "That's part of their special abilities. They're more sensitive to the environment, which is how they survive." Primates weren't the only animals that seemed to sense the quake before it happened. One of the elephants made a warning sound. And a huge lizard ran quickly for _ . The flamingoes (a kind of bird) gathered before the quake and stayed together until the shaking stopped. So what kind of vibrations were the animals picking up in the moments before the quake? Scientist Susan Hough says earthquakes produce two types of waves -- a weak "P" wave and then a much stronger "S" wave. The "P" stands for "primary". And the "S" stands for "secondary". She said she thinks the "P" wave might be what set the animals off. Not all the animals behaved unusually before the quake. For example, Smith says the zoo's giant pandas didn't jump up until the shaking actually began. But many of the other animals seemed to know something was coming before it happened. "I'm not surprised at all," Smith said. According to Brandie Smith, _ . | [

mmlu_stem | mmlu_stem_4026 | Sunscreens can offer protection from two types of ultraviolet (UV) rays : UVB, which according to the Skin Cancer Foundation, are the chief cause of sunburn and play a key role in the development of skin cancer, and UVA, which get through the skin more deeply and are largely responsible for skin aging and wrinkling, as well as skin cancer risk. The SPF measurement on sunscreens refers to the UVB protection level -- and the number may not mean what you think it does. SPF 15 doesn't protect you from 15% of UVB rays, just as SPF 100 doesn't protect you from 100% of the rays. In fact, as you get into the higher numbered SPF sunscreens (think: 50 and above), the difference in UVB protection is actually pretty small. Theoretically, though the increase in UVB protection with a super-high SPF sunscreen may be not worth considering, it may help, and certainly can't hurt, to use it -- that is, as long as you do so correctly. "The only _ is whether you're giving yourself a sense of false security," Dr. Gohara says. Indeed, as Dr. Wang also pointed out, when people choose increased SPFs, they may actually feel so protected by the product that they finally ignore proper sun protection. "When people use really high SPF products, they tend not to reuse, they tend to stay out in the sun much longer, and they don't use other protective measures such as clothing and hats," he says. Regardless of any increase in protection that a high SPF may or may not offer, one thing is certain: It doesn't give your body a free pass from sunburns, aging, or cancers, and it doesn't protect you from those things for any greater length of time than the lower SPF options. Both Dr. Wang and Dr. Gohara emphasized that, no matter what the SPF is, it's important to reapply your sunscreen every two hours. What rays can cause skin cancer according to the text? | [

mmlu_stem | mmlu_stem_8088 | A 15-year-old Saanich student who invented a flashlight powered by body heat is heading home today from California with a big prize--and an opportunity to expand on her work. St. Michaels University School student Ann Makosinski was the only Canadian among the four winners at Google's annual international science fair, beating out thousands of other young scientists from around the world. Winning the international contest was "a total shock", Ann said from San Francisco. "I definitely think it will have an influence on my future." Ann thanked her family for encouraging her interest in science, telling the judges that her first toy was a box of transistors . Ann's prize includes a $25,000 scholarship and a "once-in-a-lifetime experience" from either the European Organization for Nuclear Research, Lego or Google for her Hollow Flashlight, which has no moving parts or batteries. Ann created the flashlight for a local science fair. The inspiration for the invention came from seeing unwanted batteries and after visits to the Philippines, where she saw the need for a battery-free flashlight. A friend at school there failed in her studies because of a lack of electricity and light to study when it became dark. In her project, Ann wrote that she "made two flashlights that do not use any batteries, harmful chemicals, or kinetic energy . They do not create any noise and will always work. The flashlight's only limitation is its need for at least a 5degC temperature difference to provide usable light." A You Tube video of Ann explaining how she created the flashlight has been viewed more than 1.4 million times. Despite her success, the private school student is undecided about her career path. Ann hopes she can find a way to combine her love of film with science. The four winners were chosen from 15 finalists from eight countries. The contest attracted thousands of entries from students in 120 countries. What do we know about Ann Makosinski? | [

If she had been born 20 years earlier, she would probably have died at once. She needed two operations, but she survived without serious damage. Twenty years ago , 90% of all premature babies died. Today, doctors manage to save four out of every five, because they have better machines for breathing and better ways to feed the babies. But saving Christie's life cost more than $ 400,000.

mmlu_stem | mmlu_stem_5261 | Ants have a reputation for strength,organization and teamwork.But researchers have now discovered that a key secret to the success of ants is their ability to identify the importance of age in the work place. A study of Gentral American leaf-cutter ants has shown that the younger and stronger members are give the toughest job of cutting therough the leaves they harvest.Their sharp youn teeth do this job effectively,but as they get older their teeth become relatively worn and _ . But rather than being retired or abandoned by the group,the ageing ants are given a new role more suyted to their physical abilities.They become carriers and teansport the leaves back to the kingdom where they are harvested for food. The findings by researchers from the University of Oregon and the Oregong State University support previous research showin the survival of a leaf-cutter kingdom depends on the efficiency of is workers. "Cuting leaves is hard work,"said Dr.Robert Schofield,who led the research team."Much of the cutting is done with a V-shaped blade between teeth on their jaws.This blade starts out as sharp as the sharpest razor blade that humans have developed."But over rime the teeth become blunter and the cutting job slows down.The team estimated that,because of this age-related wear,a colony spent twice the energy cutting leaves than it would if all the ants had sharp blades.Its findings support the idea that wear and break can be significant problems for insects as well as largre animals. Like humans,leaf-cuttre ant recognize that older members of the group can still make a worhwhile contribution to society."This study shows an advantage of social living that we are familiar with,"said Dr.Schofield.

Once a month, or more exactly, once every 29.5 days, at the time we call "full moon," its whole _ looks bright.

So in hot summers,be careful about playing sports outside. Firstly,to play sports safely in hot weather,you must drink water. Sports drinks are great for athletes,but they have so much sugar that they'll dehydrate you more. However,drinking a few bottles of sports drinks will be good for you. Secondly,be sure to take enough breaks to let your body rest. If your coach doesn't let you take enough breaks in the heat,don't wait until you feel uncomfortable. Just be honest with your coach when you need breaks. Thirdly,when you have a break,don't sit in the sun. With the sun beating down on you,you'll only heat up and sweat more. Take a seat under a tree,or even better,go indoors for a little while. Cooling yourself down can help you stay active longer. Fourthly,remember that the earlier in the day you start your exercise,the cooler it will be. If you can start practice before the sun comes up,you have a few good hours to practise in the cool hours of the morning. Also,the earlier you practise,the earlier you can finish the exercise. If you need more practice time,come back to the field later in the evening,when the sun is setting. Last but not least,you should watch what you eat.

Scientists have observed a dolphin trying to get a shy eel to come out of its hole by poking it with a dead fish. Many species of dolphin live in large societies. They have many different relationships and need a good communication system; they use a variety of sounds to communicate with each other. There is currently no evidence that dolphins have a language of their own. But scientists still have a lot to find out about these animals and so there are certain to be a few surprises in the future. At Kewalo Basin Marine Laboratory in Hawaii, the dolphin team have developed a sign langue to communicate with the dolphins, and the results are amazing. Not only do the dolphins understand the meaning of individual words, they also understand the significance of word order in a sentence. For example, when they were asked to 'touch the ball with your tail and then jump over it' they generally responded correctly and straight away, which showed that they understood the langue. Most mammals seem to enjoy play--but dolphins seems to like making their games as challenging as possible. On a beautiful day in 1997, researchers working at a beach, off the southern coast of Brazil, observed a little dog going into the sea and swimming towards the dolphins. To their surprise, the dolphins approached the dog and then started throwing it into the air. The dog seemed to enjoy the 'game' and continued playing with the dolphins for more than an hour. From then on, different dogs were seem trying to interact with the dolphins. Dolphins live in a very different world to ourselves, but they are very good at our 'intelligence tests'. For example, they will jump out of the water when they hear a whistle noise. They do this because they will get a fish as a reward. There is still much to learn about these flexible problem-solvers, but from the evidence so far, it would seem as though dolphins are very intelligent.

A small food store owner decided one day that keeping records of the inventory of his stock and the associated prices were an extremely laborious process, and so, in 1948, he contacted The Drexel Institute of Technology in a bid to work towards a solution. Bernard Sliver rose to the challenge and set out to study the problem and began working on a solution involving an automatic way of keeping track of items that had been sold. Sliver and a group of students from the institute realized their answer in the form of ultraviolet light , ink and a scanner. The system worked initially, but possessed some negatives. It was incredibly costly to carry out on a large scale and the system was also unstable. If the invention was to become commonplace in grocery stores, these two problems had to be solved. The patent for the bar code system was filed by Sliver and one of his students, Woodland. The patent was not granted immediately; in fact, it took three years for the patent agency to grant their invention patent for the barcode, occurring on 7thOctober, 1952. Despite the patent being issued, the system was still not welcomed by the majority of store owners. It was not until 1966 that the system began moving its way into more and more grocery stores. This system was soon criticized, as there was no central mechanism for controlling uniformly coded items. In 1970, Logicom developed the Universal Grocery Products Identification code( UGOIC), soon shortened to Universal Identification Number (UPC). It was Marsh's superstore, in Troy, which was the very first store to install this complex barcode reading system, and its popularity has soared ever since, and is obviously now commonplace in all types of stores worldwide.

mmlu_stem | mmlu_stem_12984 | It is the 22ndcentury and it is very popular to change people's bodies. Mr. Smith decided to change his body. He changed his big nose to a small one, and his old and gray hair to short and blond hair. He also bought new green eyes, new hands, new arms, new knees and new feet. Mrs. Smith was happy because Mr. Smith's new feet didn't smell as bad as his old feet. However, something bad happened. One morning, Mr. Smith woke up and his new nose didn't work. The next morning he couldn't hear anything. Then his new blond hair went gray, and his new knees didn't move. And finally he could see nothing with his green eyes. It was really terrible. Mr. Smith wanted his old body back. However, he had to pay 100,000 euro for his old body. It was expensive but Mr. Smith still got his own body back.

mmlu_stem | mmlu_stem_8416 | A group of Russian criminals have stolen l.2 billion username and password combinations for more than 500 millione-mail addresses. It's the largest known theft on the Internet, according to a report of The New York Times. Cyber security firm Hold Security discovered the security breach( ). The firm found that the group of criminals collected personal information from 420,000 websites, including household names and small Internet sites. The criminals were based in a small city in south central Russia. They hacked websites inside Russia as well as big companies in the U.S. and other countries ,The New Times reports. The criminals found hundreds of thousands of weak websites and attacked their coding,Hold Security said. Alex Holden is chief information security officer of Hold Security. "The hackers did not just target U.S. companies;they targeted any website they could get," Holden said. "And most of these sites are still easy to attack". According to Hold Security, the criminals have been using the stolen information to send junk mail through e-mail and on social networks like Twitter. They can also use the 500 million stolen e-mail -addresses to plan other crimes. They could use information from bank e-mails to steal your identity or sell the e-mail address to other criminals to make quick cash. The reported break-ins are the latest events to raise doubts about security at big and small companies. Last winter, hackers stole 40 million credit card numbers and 70 million addresses, phone numbers and other personal information from the retailer Target Corp. The brand is still working to regain its shoppers' trust. John Prisco is a CEO of a security firm. He says security hacks are more common than many people and companies realize. " _ ," Prisco said in an e-mailed statement. So many cyber breaches today are not actually reported, because companies are losing information and they are not even aware of it. " Security experts believe hackers will continue breaking into computer networks unless companies become more protective of personal information.

mmlu_stem | mmlu_stem_13486 | 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, Samsung CEO spent a lot of time talking about the Internet things. He said that four 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 Review, 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. Moreover, 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 members by late 2015. 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? It may happen sooner than you think.[:] According to Samsung CEO, when will his product be part of the Internet of things? | [

mmlu_stem | mmlu_stem_10711 | Can you imagine traveling to work in a one-man submarine? Scientists believe that someday one-man submarines will be as numerous as automobiles today. One says," One day soon, men will walk on the ocean floor as they do on the street. " Perhaps during your life time, people will travel, work and live under the sea. Ships carrying oil and articles of trade will move beneath the ocean. Passenger ships will be built to travel underwater, where storms cannot delay them or make people seasick. Special underwater ships will be designed for mining, fishing, and exploring unknown areas. For military use, there may be submarines that can fly and then dive underwater to approach the battle area without being seen. First, however, the human problems associated with living in the ocean will need to be studied in detail. Many of these problems are the same as the problems of living in outer space: pressure, lack of oxygen, and weightlessness. Already scientists have begun to study these problems. In 1963 and 1964 scientists and Navy divers lived and worked underwater for several days in two projects which were called Sealab I and Sealab II. The Sealab II experiment kept the scientists and divers 215 feet below the surface for thirty days, studying marine biology, temperature, pressure, currents, and ocean bottom geology. Many puzzling questions remain unanswered, however. Man's warm blood makes it difficult for him to live long in the sea without some kind of warmth. Can our blood be changed to fit new water surroundings? What will happen to our muscles if we live in the water very long? Will they become soft away from our usual land existence? Will bones become weak and our blood pressure change? Scientists are searching for answers. By studying plants and animals deep in the ocean, scientists may find a cure for some of our most serious human diseases. We may learn to use plants to increase our world food supply. Engineers may learn to use the power of the sea by building huge walls to catch the force of the tides. Whether we live in the sea or in outer space, first of all we should think of _ | [

mmlu_stem | mmlu_stem_5124 | For most kids, height isn't something they can change, so what do you do if you don't like how tall or short you are? It might be girls feeling too tall and boys feeling too short but some really tall boys might not like all that height and some shorter girls might get tired of all the jokes or of feeling like they're staying little while their friends are growing up. If you are still worried about your height, talk to your parents and your doctor. Most kids don't have a growth problem that needs help from a doctor, but it's always OK to ask if you're concerned. So for most kids, it seems like there's not much to do but wait to see how it all turns out. But you can do something right now: eat healthy and take care of yourself. If you get the nutrition , sleep, and exercise you need, you're likely to reach your maximum height. In other words, you'll grow as tall as you were meant to grow. And even though you may hear people say it, taking extra vitamins or supplements that you can buy in a store won't help you get taller. Just stick to a healthy diet if you want to be the tallest you can be! Kids who wish they weren't so tall should still eat healthy and take care of themselves, of course. Eating less won't make you end up any shorter unless you really starved yourself and made yourself sick. As they get older, most kids learn to feel comfortable with their height, whether they turn out tall, short, or somewhere in between.

mmlu_stem | mmlu_stem_7049 | Parties, iPods, concerts, movies, TV shows, video games, traffic. All of these things of the modern world make life entertaining and enjoyable. But our 21st-century lifestyle is also loud and, if we don't take notice, it can have an effect on our hearing. Most teenagers don't think about hearing loss. But if you experience any of the followingsymptoms , you may already be hearing damaged: you make efforts to hear normal talk, you have to turn up the TV or radio so high that others complain, you watch other people's expressions to understand what they are saying, you ask people to repeat themselves, you misunderstand what people are saying or you hear ringing in your ears. iPods and other MP3 players are as common as the clothes you wear, and just as fashionable. But if you turn up an iPod to more than 60 percent of itsmaximum volume , and listen to music for more than an hour, you are asking for trouble. And, it does not matter if the music you play is classical, rock or heavy metal. Some researchers find that young people who break the so-called 60-percent/60-minute rule in listening to iPods are at the risk of suffering hearing loss. Why is an iPod dangerous? With ear buds placed directly in the ear canal and high-volume music played over a long period of time, it's like working in a loud factory all day, being amaintenance person under a jet airplane or using ajackhammer on a building site. Similarly, iPod music can cause a short time orpermanent hearing damage. A loud iPod can cause aruptured eardrum and, over time, may cause permanent damage to the tiny hairs in the inner ear. If these tiny hairs are damaged, they cannot effectively send sounds to theauditory nerves that connect to the brain. If this happens, hearing loss becomes permanent. Which of the following shows that you are suffering hearing loss? | [

"You have to read others' expressions to understand them.",
"You can only understand others over the phone.",

mmlu_stem | mmlu_stem_2367 | Surprisingly, no one knows how many children receive education in English hospitals, still less the content or quality of that education. Proper records are just not kept. We know that more than 850,000 children go through hospital each year, and that every child of school age has a legal right to continue to receive education while in hospital. We also know there is only one hospital teacher to every 1,000 children in hospital. Little wonder the latest survey concludes that the extent and type of hospital teaching available differ a great deal across the country. It is found that half the hospitals in England which admit children have no teacher. A further quarter have only a part-time teacher. The special children's hospitals in major cities do best; general hospitals in the country and holiday areas are worst off. From this survey, one can estimate that fewer than one in five children have some contact with a hospital teacher--and that contact may be as little as two hours a day. Most children interviewed were surprised to find a teacher in hospital at all. They had not been prepared for it by parents or their own school. If there was a teacher they were much more likely to read books and do math or number work; without a teacher they would only play games. Reasons for hospital teaching range from preventing a child falling behind and maintaining the habit of school to keeping a child occupied, and the latter is often all the teacher can do. The position and influence of many teachers was summed up when parents referred to them as "the library lady" or just "the helper". Children tend to rely on concerned school friends to keep in touch with school work. Several parents spoke of requests for work being ignored or refused by the school. Once back at school children rarely get extra teaching, and are told to catch up as best they can. Many short-stay child-patients catch up quickly. But schools do very little to ease the anxiety about falling behind expressed by many of the children interviewed. We can conclude from the passage that the author is _ . | [

What about the people who invented the traffic light and the windshield wiper ? Shouldn' t we know who they are? Joan Mclean thinks so. In fact, Mclean, a professor of physics at Mountain University in Range, feels so strongly about this matter that she' s developed a course on the topic. In addition to learning "who" invented "what" , however, Mclean also likes her students to learn the answers to the "why" and "how" questions. According to Mclean, "When students learn the answers to these questions, they are better prepared to recognize opportunities for inventing and more motivated to give inventing a try. " Her students agree. One young man with a patent for an unbreakable umbrella is walking proof of McLean's statement. "If I had not heard the story of the windshield wiper' s invention," said Tommy Lee, a senior physics major. "I never would have dreamed of turning my bad experience during a rain storm into something so constructive. " Lee is currently negotiating to sell his patent to an umbrella producer. So, just what is the story behind the windshield wiper? Well, Mary Anderson came up with the idea in 1902 after a visit to New York City. The day was cold and stormy, but Anderson still wanted to see the sights, so she jumped aboard a streetcar. Noticing that the driver was struggling to see through the snow covering the windshield, she found herself wondering why there couldn' t be a built - in device for cleaning the window. Still wondering about this when she returned home to Birmingham, Alabama, Anderson started drafting out solutions. One of her ideas, a lever on the inside of a vehicle that would control an arm on the outside, became the first windshield wiper. Today we benefit from countless inventions and innovations. It' s hard to imagine driving without Garrett A. Morgan' s traffic light. It' s equally impossible to picture a world without Katherine J. Blodgett' s innovation that makes glass invisible. Can you picture life without clear windows and eyeglasses? Tommy Lee' s invention of the unbreakable umbrella was _ | [

mmlu_stem | mmlu_stem_8289 | In traditional Chinese medicine, the body, mind and spirit cannot be divided and so the unique whole-body treatment in Tui Na can also be a useful treatment correcting any imbalances in the body's energy before symptoms and disease can develop. It also works to bring back emotional peace as well as physical health. This is why after a Tui Na treatment many people "feel good". Many people in China use Tui Na regularly to keep healthy and to deal with some specific illnesses. Tui Na is performed on the clothed body and the patient is either lying on a couch or sitting on a chair. Therapists , by using a variety of movements, will control the intensity and direction of pressure in an exact way. The unique rolling movement in Tui Na is one of the most difficult movements to learn and students have to practice sometimes for many months on a rice bag before they are allowed to practice on the human body. Stress Tui Na is of course very useful for treating stress. It spreads the energy around the whole body. It is believed that Tui Na moves the strong energy in the tight muscles to the weaker areas, thus making a more balanced body. When your energy flowing inside your body is balanced, you feel relaxed and comfortable. Tui Na is especially useful for _ shoulders and tight neck muscles. Emotions In Traditional Chinese Medicine each major organ is linked to an emotion. By balancing the energy in the organ, the related emotion will be calmed. When your emotions are out of control, you would usually turn to your doctor or perhaps a psychotherapist . But perhaps some people would not like to be seeing a psychotherapist or feel nervous about discussing their problems with others. With Tui Na, one does not need to tell the therapist anything one does not want to. The treatment of Tui Na can deal with the problem itself. But if one does need to pour out his/her worries or troubles, an active dialogue between the psychotherapist and the patient will help to get a better effect. Organs & Emotions Each major organ -- the heart, the stomach, the liver , the lungs, and etc.--are linked to a relevant emotion. The heart is linked to joy, excitement and sadness. If the heart is out of balance, the patient may dream a lot at night and often forget something important in the day. The stomach is connected with too much thinking or worrying about anxiety. When the stomach is out of balance there is often a lack of energy. The patient often feels very tired and has no interest in doing anything at all. The liver is linked to anger. In Chinese medicine, the eyes are connected with the liver, and many people who suffer from anger often suffer from eye problems.

mmlu_stem | mmlu_stem_8790 | You do something about twenty times a minute without even thinking about it--you breathe! In fact, every day you take about twenty-thousand breaths. The organs of your body that allow you to breathe are called your lungs. You have two of them that work together, located in your chest inside the rib cage. The main purpose of your lungs is to breathe in good air and breathe out bad air. The good air contains oxygen, which your body needs. The bad air is a gas called carbon dioxide, which your body cannot use. When you breathe in through your nose or mouth, air travels down the back of your throat. It passes through your voice box and into your trachea, or windpipe. Your trachea is divided into two air passage tubes. One leads to your left lung. The other leads to your right lung. Inside your lungs, oxygen is removed from the air you breathe and pumped into blood cells. Your lungs also get rid of harmful carbon dioxide from these cells. This process takes place inside hundreds of millions of tiny air sacs. Each adult lung is about the size of a football. When they are healthy, your lungs feel a little like a sponge and are pinkish-gray. When lungs are damaged by smoking, they can appear gray or have black spots on them.One disease that is very common in children involves the lungs. It's asthma. Asthma narrows the breathing tubes, making it harder to breathe. You probably already know that your lungs are important when you swim. But you may not know this--your lungs are the only part of your body that can float on water! Which of the following about your lungs is WRONG? | [

mmlu_stem | mmlu_stem_3600 | As if there weren't enough of them in the world already, scientists have succeeded in cloning flies. The alike fruit flies are the first insects ever cloned, says the Canadian team that created them. The question everyone asks is why anyone would want to clone flies in the first place. She hopes that the insects , which are very easy to experiment with , will help to adjust the cloning process in other animals and even in humans, where the technique is being researched to aid production of therapeutic stem cells. In cloning, the DNA-containing nucleus of an adult cell is injected into an egg whose own nucleus has been removed. At the moment, the majority of cloned mice, sheep and other animals die before birth. It is thought this is because the adult DNA is not properly 'reprogrammed'. Using flies, researchers might discover genes that are important for this reprogramming, and that have matches in other animals. That is because it is relatively easy in flies to knock out the function of a single gene and then attempt cloning with these cells, which will test whether that gene is important. If such genes are confirmed, then in theory cloned mammalian embryos might be grown in selected solutions that change the activity of those genes to improve the technique's success rate. Although some groups have attempted to clone insects before, Lloyd says this is the first time it has been successful. The team used a slight difference on the standard cloning process: they transferred nuclei taken from embryos rather than fully-grown adult cells. They sucked several nuclei (pl)out of developing fly embryos, and injected them into a fertilized fly egg. From over 800 early attempts, they cloned five adult insects, the group reports in the journal Genetics. The failure of most cloned animals is due to _ . | [

Jeb put his bag down quickly and pulled his jacket open with both hands, making himself look big to the cougar. It worked. The cougar hesitated, ready to attack Jeb, but ready to forget the whole thing, too. Jeb let go of his jacket, grasped Tom and held him across his body, making a cross. Now the cougar's enemy looked even bigger, and it rose up, ready to move away, but unfortunately Tom got scared and struggled free of Jeb. "Tom, no!" shouted his father. But Tom broke and ran and that's the last thing you do with a cougar. The second Tom broke free, Jeb threw himself on the cougar, just as it jumped from the rock. They hit each other in mid-air and both fell. The cougar was on Jeb in a flash, forgetting about Tom, which was what Jeb wanted. Cougars are not as big as most people think and a determined man stands a chance, even with just his fists. As the cougar's claws got into his left shoulder, Jeb swung his fist at its eyes and hit hard. The animal howled and put its head back. Jeb followed up with his other fist. Then out of the corner of his eye, Jeb saw Tom. The boy was running back to help his father. "Knife, Tom" shouted Jeb. The boy ran to his father's bag, while Jeb stated shouting as well as hitting, to keep the cougar's attention away from Tom. Tom got the knife and ran over to Jeb. The cougar was moving its head in and out, trying to find a way through the wall Jeb was making out of his arms. Tom swung with the knife, into the cougar's back.

mmlu_stem | mmlu_stem_9296 | Songs that make our hearts happy can make them stronger too, US researchers reported on Tuesday. They found that when people listened to their favorite music, their blood vessels _ in much the same way as when they are laughing, or taking blood medications. "We have a pretty impressive effect," said Dr Michael Miller, director of preventive cardiology at the University of Maryland Medical Center in Baltimore. "Blood vessel diameter improved," he said. "The vessel opened up pretty significantly. You can see the vessels opening up with other activities such as exercise." A similar effect is seen with drugs such as statins. When blood vessels open up more, blood flows more smoothly and is less likely to form the clots that cause heart attacks and strokes. "We are not saying to stop your statins or not to exercise but rather to add this to an overall program of heart health," said Miller, who presented his findings to a meeting of the American Heart Association in New Orleans. Miller's team tested 10 healthy, non-smoking men and women, who were told to bring their favorite music. They spent half an hour listening to the recordings and half an hour listening to music they said made them feel anxious while the researchers did ultrasound tests designed to show blood vessel function. Compared to their normal baseline measurements, blood vessel diameter increased 26 percent on average when the volunteers heard their joyful music. Listening to music they disliked -- in most cases in this group heavy metal -- blood vessels narrowed by six percent, Miller said. Miller said he came up with the idea after discovering that laughter caused blood to literally flow more smoothly. "I asked myself what other things make us feel really good, besides calories from dark chocolate of course. Music came to mind. ... It makes me feel really good," he said. Most of the volunteers chose country music but Miller said the style is not so important rather than what pleases each individual. It can be inferred from the passage that _ . | [

mmlu_stem | mmlu_stem_6383 | There are many commonly held beliefs about eye glasses and eyesight that are not proven facts. For instance, some people believe that wearing glasses too soon weakens the eyes. But there is no evidence to show that the structure of eyes is changed by wearing glasses at a young age. Wearing the wrong glasses, however, can prove harmful. Studies show that for adults there is no danger, but children can develop loss of vision if they have glasses inappropriate for their eyes. We have all heard some of the common myths about how eyesight gets bad. Most people believe that reading in dim light causes poor eyesight, but that is untrue. Too little light makes the eyes work harder, so they do get tired and strained. Eyestrain also results from reading a lot, reading in bed, and watching too much television. However, although eyestrain may cause some pain or headaches, it does not permanently damage eyesight. Another myth about eyes is that they can be replaced, or transferred from one person to another. They are close to one million nerve fibers that connect the eyeball to the brain, so it is impossible to attach them all in a new person. Only certain parts of the eye can be replaced. But if we keep clearing up the myths and learning more about the eyes, some day a full transplant may be possible. If an adult wears inappropriate glasses, _ . | [

mmlu_stem | mmlu_stem_5397 | Question: What is more astonishing than a 60-ton whale on a flatbed truck being driven down the street? Answer: A 60-ton whale on a flatbed truck exploding and raining blubber ( fat of whales) all over the sidewalk. That's what happened in Taiwan recently, when a dead sperm whale being shipped to the Halobios Research Center for an autopsy developed an extremely bad case of gas and blew up before it reached its destination. The whale was found alive on a prefix = st1 /Taiwanbeach last weekend, and died shortly after it was discovered. Since the 56-foot whale was the largest whale ever beached onTaiwan's shores, scientists wanted to study it and perform an autopsy for educational purpose. Obviously, too much time passed between when the animal died and the time it was set to be moved to the autopsy location, because it had already started to go bad. When things rot, they give off gases as a by-product. In the whale's case, the gases were trapped in its belly. The pressure inside the rotting creature grew so much that it popped like an over-filled balloon. Unfortunately, it was on a truck in the middle of the city of Taiwanat the time--- cars and shops lining the street were covered with whale bits and juices, much to their owners' discouragement. According to the news reports, traffic was tied up for hours while officials tried to clean up the streets. Newspaper editors worldwide were probably smiling to themselves, since they had a ready-made headline--- several reports about the incident were titled " There She Blows!" after the famous line from the book Moby Dick.

But none watched more closely than eighteen-year-old Ted, as Ted's insects were on board the shuttle. The Shuttle Student Involvement Program invited students to make a science experiment. The experiment would be done by astronauts on the space shuttle. Ted had always been interested in space and flight. Insect flight especially interested him. Ted noticed that insects need gravity to take off and land. They need gravity to fly in a straight line. But in space, there is no gravity. Could insects fly in zero gravity? That is what Ted wanted to find out. Ted made an experiment called "Insect in Flight Motion Study". He entered his experiment and soon news came that _ . A large team of scientists and engineers helped Ted get his experiment ready to fly. There were many questions to be answered first. What kind of insects would Ted use in his experiment? The insects would have to be strong enough to live on the shuttle for nine days without much food. What kind of container would hold the insects? Would the insects die during the shuttle flight? After months of hard work, the "insectronauts" were chosen. A group of moths, flies, and honeybees were put into a special box and put onto the space shuttle. When Columbia flew into space, it was carrying insect passengers. On March 24, astronauts Gordon Fullerton and Jack Lousma took out the box that held the insects. They began filming the insects with a special video camera. When the space shuttle landed Ted was able to watch the video film of insects. Just as he thought, most of the insects did have trouble flying in zero gravity. The flies did well. But the moths' flight seemed "uncontrolled". They would often just hang in the air. The bees had the most trouble. They couldn't fly at all! The film showed bees spinning around in all directions. Others were just floating about in the box. Ted learned the answer to his question about insects' flight in zero gravity. But he also learned a lot more. He learned about the hard work needed in making a successful experiment. What did Ted want to find out? | [

mmlu_stem | mmlu_stem_6942 | Space is a dangerous place, not only because of meteors but also because of rays from the sun and other stars. The atmosphere again acts as our protective blanket on earth. Light gets through, and this is necessary for plants to make the food that we eat. Heat, too, makes our environment endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation but their spacesuits or the walls of their spacecraft, if they are inside, do prevent a lot of radiation damage. Radiation is the greatest known danger to explorers in space, The unit of radiation is called "rem" Scientists have reason to think that a man can put up with far more radiation than 0.1rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage. A person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will not be discovered until the birth of _ children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation and , during the outward and return journeys, the Apollo crew accumulated a large amount of rems. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short.

mmlu_stem | mmlu_stem_9920 | 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. Which of the following about carbon monoxide poisoning is true? | [

It shows an astronaut struggling to live on Mars. But would it actually be possible to live on the Red Planet? While the idea of living on Mars is great, the reality does not look as good. Mars does not have a friendly atmosphere for humans. There is very little oxygen there. And because of its distance from the sun, it is also very cold. The temperature on Mars can be -62 degrees on average. This is much too cold for humans. However, scientists say it might be possible to live there even without a good atmosphere. Daytime on Mars is almost the same as Earth's. It means there's enough sunlight to grow plants inside safe buildings. However, they would have to grow in soil from Earth. Mars does not have a strong enough atmosphere to stop the radiation coming from space, which makes it dangerous to grow things in the soil. The radiation is also bad for our health. If we want to live there healthily, we need to build our homes under the ground or within the rocks on the planet. This would protect humans from the radiation and also some heat.
