mmlu_stem | mmlu_stem_13021 | How many things can you see in the night sky? A lot! On a clear night you can see the moon, some planets, and thousands of sparking stars. You can see even more with a telescope. You might see that many stars look larger than others. You might see that some stars that look white are really red or blue. With bigger and bigger telescopes you can see more and more objects in the sky. And you can see those objects in more and more detail. But scientists believe there are some things in the sky that we will never see. We won't see them with the biggest telescope in the world, on the clearest night of the year.That's because they're _ . They're the mysterious dead stars called black holes. You might find it hard to imagine that stars die. After all, our sun is a star. Year after year we see it up in the sky, burning brightly and giving us heat and light. The Sun certainly doesn't seem to be getting old or weak. But stars do burn out and die after billions of years. As a star's gases burn, they give off light and heat. But when the gases run out, the star stops burning and begins to die. So next time you look up at the night sky, remember: there's more in the sky than we can see! Which of the following is NOT TRUE according to the passage? | [
"We might see that many stars look larger than others with a telescope",
"We might see that some stars that look white are really red and blue with a telescope.",
"We can see some objects in more and more detail with bigger and bigger telescopes.",

mmlu_stem | mmlu_stem_4633 | A long time ago, there lived a poor man whose real name has been forgotten. He was little and old and his face was wrinkled, and that was why his friends called him Mr. Vinegar. His wife was also little and old, and they lived in a little old cottage at the back of a little old field. "John," said Mrs. Vinegar, "you must go to town and buy a cow. I will milk her and churn butter and we shall never want for anything." "That is a good plan," said Mr. Vinegar, so he started off to town while his wife waited by the roadside. Mr. Vinegar walked up and down the street of the town looking for a cow. After a time, a farmer came that way, leading one that was very pretty and fat. "Oh, if I only had that cow," said Mr. Vinegar, "I would be the happiest man in the world!" "She's a very good cow," said the farmer. "Well," said Mr. Vinegar, "I'll give you these 50 gold pieces for her." The farmer smiled and held out his hand for the money, "You may have her," he said, "I always like to oblige , my friends!" Mr. Vinegar took hold of the cow's halter and led her up and down the street. "I am the luckiest man in the world," he said, "for only see how all the people are looking at me and my cow!" But at one end of the street, he met a man playing bagpipes . He stopped and listened -- Tweedle Dee Tweedle Dee. "Oh, that is the sweetest music I ever heard," he said, "and just see how all the children crowd around the man and give him pennies! If I only had those bagpipes, I would be the happiest man in the world!!" "I'll sell them to you," said the piper. "Will you? Well then, since I have no money, I will give you this cow for them." "You may have them," answered the piper, "I always like to oblige a friend." Mr. Vinegar took the bagpipes and the piper led the cow away. "Now we will have some music," said Mr. Vinegar, but try as hard as he might, he could not play a tune. He could get nothing out of the bagpipes but "squeak, squeak". The children instead of giving him pennies laughed at him. The day was chilly and in trying to play the pipes, his fingers grew very cold. He wished he had kept the cow. He just started for home when he met a man who had warm gloves on his hands. "Oh, if I only had those pretty gloves," he said, "I would be the happiest man in the world." "How much will you give for them?" asked the man. "Oh, I have no money, but I will give you these bagpipes," answered Mr. Vinegar. "Well," said the man, "you may have them for I always like to oblige a friend." Mr. Vinegar gave him the bagpipes and drew the gloves on over his half frozen fingers. "How lucky I am," he said as he trudged homeward. His hands were soon quite warm, but the road was rough and the walking hard. He was very tired when he came to the foot of the steep hill. "How shall I ever get to the top?" he said. Just then he met a man who was walking the other way. He had a stick in his hand which he used as a cane to help him along. "My friend," said Mr. Vinegar, "if only I had that stick of yours to help me up this hill, I would be the happiest man in the world!" "How much will you give me for it?" asked the man. "Well, I have no money, but I will give you this pair of warm gloves," said Mr. Vinegar. "Well," said the man, "you may have it for I always like to oblige a friend." Mr. Vinegar's hands were now quite warm, so he gave the gloves to the man and took the stout stick to help him along. "How lucky I am!'' he said as he toiled upward. At the top of the hill he stopped to rest. But as he was thinking of all his good luck that day, he heard someone calling his name. He looked up and saw only a green parrot sitting in a tree. "Mr. Vinegar, Mr. Vinegar," it cried. "What now?" said Mr. Vinegar. "You're a dunce , you're a dunce!'' answered the bird, "you went to seek your _ and you found it, then you gave it for a cow, and the cow for some bagpipes, and the bagpipes for some gloves, and the gloves for a stick which you might of cut by the roadside. He He He, you're a dunce! You're a dunce!'' This made Mr. Vinegar very angry. He threw the stick at the bird with all his might. But the bird only answered, "You're a dunce! You're a dunce!" And the stick lodged in the tree where he could not get it again. Mr. Vinegar went on slowly for he had many things to think about. His wife was standing by the roadside and as soon as she saw him, she cried out, "Where's the cow? Where's the cow?" "Well, I just don't know where the cow is," said Mr. Vinegar. And then he told her the whole story. How many exchanges happen in the passage? | [

mmlu_stem | mmlu_stem_6109 | Surface Exploration. Robots make great explorers on planets,moons,and other landing areas. Aside from earth,just about every surface in the solar system is unsafe for humans to explore. The air on most other planets is insufficient for humans to breathe,making it necessary to wear a space suit and oxygen equipment. The temperatures on these surfaces are much too hot or much too cold for any humans to withstand .Plus there would be complications with radiation,weather,and a lack of gravity. Robots have much less limitation in these areas and can survive much longer under these conditions. Data Collection. Robots are designed for collecting scientific data. Robots are also able to perform many tasks at a time and can process information much quicker and more efficiently. Important scientific projects from detecting minerals,analyzing ground samples,and finding water are all performed much quicker and more accurately by robots. Cost Effective. The use of robots has made the cost of space exploration much less expensive than it would cost for humans to do the work. In order to successfully send humans into space we would need to build a vehicle that can not only carry humans,but also enough food and water to keep them alive for the duration of the trip. Moreover,robots have no problems working for hours on end. Robots never complain,they don't require food or water,and they never need a bathroom break. Space Travel. Over the past 30 years or so there have been many different types of robots used successfully in the exploration of space. Perhaps the most famous and successful robots are the Spirit and Opportunity who have both been exploring the surface of Mars. They have both been very successful with experiments on soil and rocks and have even found evidence of water in Mars' history. According to the passage,which of the following is NOT true? | [
"The use of robots in space exploration costs more than the use of humans.",
"It may be dangerous for humans to explore the solar system except the earth.",
"Both the Spirit and Opportunity have found the evidence of water in the Mars.",

mmlu_stem | mmlu_stem_14965 | Can you imagine astronauts' everyday life in space? They also need to eat, sleep, exercise and relax. They do the same things as us, but they do them differently. On Earth, we put food on a plate. _ holds the food down and keeps it on a place. But there is almost no gravity in space, so food can float away, and astronauts must eat carefully. Sleeping is very different in space. Some astronauts like to float in the air, but most like to be in a sleeping bag. They tie the bag to a wall so that they won't float away at night. Exercise is very important in space. On Earth, your legs carry your body, but in space, astronauts float, so they do not use their legs often. This is very bad for their legs, so they must exercise for thirty minutes every day. After a day's work, astronauts relax.

mmlu_stem | mmlu_stem_9940 | The worldwide increase in the use of cellphones has caused concerns regarding possible harmful effects caused by cellphone radiation. People are particularly concerned that the radiation will put cellphone users at a higher risk of suffering from cancer. However, studies of the association between cellphone use and the risk of brain cancer have reached different conclusions(some, but not all, studies showed increased risk). Researchers conducted a study to examine if cellphone radiation affected regional activity in the human brain. The study, conducted between January 1 and December 31, 2009,included 47 participants. Cellphones were placed on the left and right ears, and brain imaging was performed to measure brain glucose metabolism twice: one with the right cellphone activated for 50 minutes("on" condition) and once with both cellphones deactivated("off" condition). An analysis was conducted to check the association of metabolism and cellphone radiation. The scans were compared to assess the effect of cellphone use on brain glucose metabolism. The researchers found that whole-brain metabolism did not differ between the on and off conditions. However there were regional effects. Metabolism in some brain region was higher (about 7 percent) for cellphone on than for cellphone off conditions. This indicates that the regions expected to absorb more cellphone radiation were the ones that showed the larger increases in glucose metabolism. These results provide evidence that the human brain is sensitive to the effects of acute cellphone radiation. However, how cellphone radiation could affect brain glucose metabolism is unclear. Concerns have been raised by the possibility that cellphone radiation may _ brain cancer. Results of this study provide evidence that acute cellphone radiation affects brain metabolic activity. However, these results provide no information as to their connection regarding possible carcinogenic effects (or lack of such effects) of chronic cellphone use. Further studies are needed to assess if these effects could have long-term harm. What does the passage mainly talk about? | [

mmlu_stem | mmlu_stem_10330 | Larry was on another of his underwater adventures but this time, it was different. He decided to take his daughter along with him. She was only ten years old. This would be her first trip with her father on what he had always been famous for. Larry first began diving when he was his daughter's age. Similarly, his father had taken him along on one of his adventures. Since then, he had never looked back. Larry started out by renting diving suits from the small diving shop just along the shore. He had hated them. They were either too big or too small. Then, there was the instructor. He gave him a short lesson before allowing him into the water with his father. He had made an exception. Larry would never have been able to go down without at least five hours of theory and another similar number of hours on practical lessons with a guide. Children his age were not even allowed to dive. After the first adventure, Larry's later diving adventures only got better and better. There was never a dull moment. In his black and blue suit and with an oxygen tank fastened on his back, Larry dived from boats into the middle of the ocean. Dangerous areas did not prevent him from continuing his search. Sometimes, his was limited to a cage underwater but that did not bother him. At least, he was still able to take photographs of the underwater creatures. Larry's first adventure without his father was in the Cayman Islands. There were numerous diving spots in the area and Larry was determined to visit all of them .Fortunately for him, a man offered to take him around the different spots for free. _ The diving spots afforded such a wide array of fish and sea creatures that Larry saw more than thirty varieties of creatures. Larry looked at his daughter. She looked as excited as he had been when he was her age. He hoped she would be able to continue the family tradition. Already, she looked like she was much braver than had been then. This was the key to a successful underwater adventure. Why did Larry have to stay in a cage underwater sometimes? | [

mmlu_stem | mmlu_stem_13593 | The high school diploma is losing its value quickly, as a growing number of students graduate from school without the math and reading skills that colleges and companies require, according to a new report. The high school graduation exams that most states require students to pass before they graduate remain far too easy. Most of the exams generally test eighth-or ninth-grade level work. Today, even high school graduates who are going to have blue-collar jobs need to study the math, research and writing courses. But in high school, only students who are going to college are now required to take these courses. "If you want a good job with a good pay, it's a high-skill job," said Michael Cohen, a leading member of the America Diploma Project. The project suggests that all graduates master a wide range of skills. "A high school diploma should mean something to a company and university," said Ohio Gov. Bob Taft, who is Achieve's co-chairman. In Taft's state, about 30% students who go directly to college from high school have to take _ of English or math, he said. It's easy to see that the present high-school graduating standards are not preparing students for college education. And with high-skilled jobs increasingly headed overseas to places like India and Ireland, states need to act, he said. To prove why math and reading skills matter, the report includes real-life examples of problems students meet in college and that workers must solve each day on the job. Some states are taking actions to upgrade the high school diploma. In Texas, all high school students, starting with the 2008 graduating class, will have to take the college-prep curriculum - unless a parent agrees to an easier course load. Other states are planning similar moves. The report includes examples of reading and math skills that high-school students should have. Project leaders say they hope parents will use those examples to judge the coursework at their kids' high schools. What can we learn from the passage? | [
"Colleges require higher math and reading skills than companies.",
"It is easier for companies to find high-skilled workers in India.",

mmlu_stem | mmlu_stem_5497 | There is good and bad news for parents today. The word "mother" has been voted the most beautiful word in the English language. But "father" failed even to make it on the list of the 70 best words in a survey of thousands of non-English speakers across the world. From Ankara to Zurich, "mother" was voted above "love", "smile" and "blossom". In second place was "passion", followed by "smile", "love" and "eternity", with "fantastic", "destiny", "freedom", "liberty" and "tranquility" completing the top 10. The results were given by the British Council which carried out a huge survey of more than 40,000 people in 102 non-English speaking countries. The study was done to celebrate the group's 70th anniversary --and it threw up a few surprising words to the list. "It's interesting that 'mother', the only word of the 70 that describes a direct relationship between people, came top of the poll ",said British Council spokesman Greg Selby. "It is great to see words in the survey that are so positive and suggestive of the British Council' s purpose -- words such as 'freedom', 'liberty', 'peace'." Those surveyed were allowed to choose their words on either meaning or sound, said Mr. Selby. This explained why words that are satisfying to pronounce, like "flip-flop", made the list. Famous mothers like Kate Winslet, Elle Macpherson and Claudia Schiffer have all done their bit to make the word popular. Kate, 28, even stopped shooting Woody Allen's new film to spend more time with her young family. Singer Robbie Williams is proud to express his love for his mother, while actor Peter Kay went through a marathon British tour to pay for a new house for his mom.

mmlu_stem | mmlu_stem_13297 | When I was in the second grade,my teacher gave all her students some seeds . She told us to watch the magic of the seeds once we planted them. Excitedly,I put a few seeds in my pot. I watered them for a few days and purple flowers came out. In class,I reported back to my teacher that the magic was the purple flowers. My classmates reported back with the red,white or yellow ones. I was wondering why we didn't have green flowers. When the bell rang,we drew a conclusion" a flower garden is beautiful",and this was my first gardening experience. Years later,one day,when we drone by Naperville downtown in a summer. Mom pointed out a big land." Look,this is the community garden land." she told me." What is a community garden land?" I asked." When people live in apartments or town homes,they don't have much land. People pay a little money to rent a piece of land from the city. They can grow anything." Why don't we rent one?" I curiously asked." We don't need to. We have a house,so we have a small piece of land." A few years ago,an older couple moved in next door. They gave us some tomatoes from their garden. They grew the best tomatoes I had ever tasted. I asked my mom to buy some tomatoes just like our neighbors'. Mon said it was impossible to buy those tomatoes from the supermarket. So,last year,I decided to try. I had my dad dig out a small land in the back yard of our house,put it some peat moss and mushroom compost . For the start,I only planted some tomatoes and cucumbers. Day by day,I looked after my garden and took out weeds .I was surprised to see that cucumbers actually grow on the vine,and my tomatoes had a special kind of earthly smell. At the same time,I found myself suddenly having an interest in weather. I always wished rain to water my little garden. My brother Alex _ me." You are an old farmer now." One day,I found some tomatoes gone in one plant. I was a little sad. Who dared to steal my ttomatoes? It was a few rabbits. When I was about to drive them away,my dad stopped me and said," Alice,the rabbits are thirsty. Let them eat as much as they want. Sharing your food is a good thing." Later on,I found people picking a few tomatoes in my little garden and eating them with a satisfying smile. I never said a word. Instead,I felt joy in my heart. When harvest time came,I picked so many fresh cucumbers and delicious tomatoes. In America,people grow gardens everywhere.

mmlu_stem | mmlu_stem_11751 | We've all seen them: perfectly toned famous people on late-night television telling us that we too can develop rock-hard abdominal muscles . It's easy! Just pay $149.99 for the Torso Track or $149.75 for the Ad-Doer and watch those unwanted inches leave your waist. Americans spend tens of millions of dollars on various products to firm up their fat around the waist. And did they work? Not necessarily. Independent studies have concluded that most of these products -- no matter who approved them or how expensive they are -- shape your midsection no better than old-fashioned stomach crunches . Some can even cause injury -- like the $518.99 Body Shaper-Q8SP, which left electrical burns on some researchers at the University of Wisconsin, La Crosse. Others, like the popular Ab-Doer, typically burn less energy than a gentle walk, according to a study to be published in September by the American Council on Exercise. The fact is that many Americans don't have the biological makeup to develop an obvious abdominal muscles. They are either unable to get the necessary muscle mass or they can't lose enough fat to make a difference. Even if the underlying muscles are well developed, all it takes to hide it is one-sixteenth of an inch of fat. That's enough to exclude most healthy women as well as plenty of guys who do crunches every day. So what works best? In its new study, the exercise experts researched on the results of the popular Ab-Doer. A lengthy TV advertisement promises that just 10 minutes a day performing such movements as "Body Boogies" and "Good Mornings" will "help form those muscles the fun and easy way without diets." Steven Loy, professor at California State University, Northridge, tested the promise by measuring the electrical activity produced by the abdominal muscles during three Ab-Doer movements. He and his colleagues then compared the results with those produced during traditional exercises. They determined that the muscles were no more active, and in some cases less so, when exercisers were using the Ab-Doer. Taking a broader approach, researchers at San Diego State University compared 13 abdominal exercises for their ability to develop the central abdominal muscles. They concluded, in a report published in May, that the most effective exercises kept turning the body and worked the muscles the entire time. Among the winners: the bicycle movements -- so called because it looks as if you are riding a bike while lying flat on the floor -- and exercises performed on the "Captain's Chair", a product typically found in gyms that helps hold the body in the air while you raise your legs up toward your chest. Researchers suggested that a varied routine of the different exercises could deliver the best results. According to the author, it's difficult for many Americans to get visible firm abdominal muscles mainly because _ . | [

When they got to the foot of the mountain, there was no sign of Jake. Jake couldn't find his ski anywhere. In the end, he decided to take off his other ski and walk down the mountain. But he couldn't work out the right way to go. It was now getting dark and he was a long way from any place of safety. He knew that he might die that night in the cold temperatures. But Jake kept calm. At home, Jake watched a lot of programmes about living in difficult situations. He remembered the advice from these programmes and knew that he should build a hole in the snow. He made a hole so the wind couldn't blow into it. Outside his hole, the temperature fell to a dangerous -15degC that night, but inside it Jake was safe from the cold. After the long evening passed, Jake began to think his way out. He had to get down the mountain. The TV programmes always said, "If you are lost, you should find someone else's tracks through the snow and follow them." "I wanted to live my life." remembered Jake, "So I got up and I found some ski tracks and I followed those." He walked and walked and finally saw lights... His mum was very happy when she heard her son was saved. Amazingly, Jake didn't even have to go to hospital. He got through the terrible experience without any injuries. So, the next time someone says that watching TV is a waste of time, think of Jake. Sometimes TV can save your life! . What was the most important decision Jake made for his safety? | [

mmlu_stem | mmlu_stem_2434 | An Australian man has beaten 75 other contestants from around the world to win a race up the stairs of the world's tallest building, Taipei 101. Paul Crake,30, ran up 91 floors containing 2,046 steps in 10 minutes, 29 seconds. Mr. Crake, who has won a similar race up the Empire State Building five times, won $5,920 in prize money. The women's race was won by Austrian Andrea Mayr, who finished in 12 minutes,38 seconds and also won a $5,920 prize. Austrian Rudolf Reitheiger, who beat Mr. Crake in this year's Empire State Building Race, came second in the men's competition. Mr. Crake and Ms. Mayr missed out on the offer of $30,000 for completing the grueling race in under 10 or 12 minutes respectively. A further 1,001 people took part in a so-called "self-challenging" race up the skyscraper. Taipei 101 is 508 meters tall and was finished in 2003, although Chinese developers have said Shanghai's World Financial Center will be taller when completed in 2007. "Tower-running" races take place up the tallest buildings and structures across the world. The Sears Tower in Chicago, the CN Tower in Toronto and the Azrieli Tower in Tel Aviv have all held recent events. Runners also race up the longest staircase in the world-the service staircase for the Niesenbahn railway near Spiez, Switzerland, which has 11,674 steps. At event for the long--distance stairway runners also takes place in Radebeul, Germany, where competitors run up 397 stairs 100 times to equal the height of Mt everest.

Using a tiny microchip which is implanted into the arm, they have come up with a replacement for cash or credit cards that cannot be left at home or dropped on the bus. The Verichip is about the size of a grain of rice and works using radio frequency identification technology. At a shop, a radio frequency "reader" would send a signal and the chip in your arm would respond with your unique identity number. That would give the "reader" your financial information, and money could be taken directly from your accounts and you wouldn't even have to reach for your wallet. The company also hopes to include other information on the chip, such as medical records, building security codes and passwords, making life even easier. But not everyone is happy with the developments. Critics say that a lot can go wrong with the chip. A clever thief could build a fake reader that would steal your information without you knowing. So your money could still be stolen. Privacy is a big issue too. Stores, or even the government, only need to track the chip to find out what you buy, how much you spend and where you go. And if you wanted to get rid of your chip, you would need an operation to remove it. Which is true of the Verichip? | [

mmlu_stem | mmlu_stem_2938 | The kiwi bird The kiwi bird is a flightless bird,about the size of a chicken. It sleeps during the day and is active at nighttime. It has a long beak that is onethird the length of its body, and its beak actually has nostrils at the end. The kiwi is the only bird with this feature. Another unique feature of the kiwi is that it has no tail. It has thick brown hairlike feathers. This bird has many physical features unlike any other bird on earth. Kiwi birds have been called a genetic leftover. Their characteristics seem very odd to us probably due to the fact that they haven't evolved much at all. They are suspected to be about 8 million years old. That's 7 million years older than humans. Due to New Zealand's isolated environment, it has been safe from predators and hasn't needed to do much adapting. They just hang around. With its long beak, the kiwi digs up and chows down on worms. A kiwi is almost blind; it can see about six feet at night and around two feet during the day,so when it comes to hunting the kiwi is not well equipped.It uses the nostrils on its beak to find its food and then picks up the worms with its beak. The kiwi bird is native of New Zealand.It is the island country's national bird, and is rare anywhere but here and a few Pacific island neighbors. Of course,it is available for viewing at certain zoos.It has stayed in its native land due to the facts that it is an isolated island and that kiwis can't fly. Kiwi birds are extremely unique in the bird world. Though they are the size of chickens, they lay eggs the size of ostrich eggs, weighing around a pound each.Their enormous eggs are the largest in the bird world, compared to their bodies.

mmlu_stem | mmlu_stem_10825 | When you were young, ginger ale may have been a popular choice for reducing the unpleasant feelings caused by your upset stomach on the road to get to school. For years, ginger has been used to reduce the effects of nausea . But do you know it's now also being looked at to fight cancer? Scientists have discovered that ginger can kill cancerous cells in two different ways. On the one hand, ginger causes the cancer cells to "commit suicide" by destroying themselves while leaving the surrounding healthy cells untouched. Ginger can prevent the growth of diseased cells by destroying the environment they grow in. On the other hand, ginger tricks the diseased cells and causes them to fight among themselves. Researchers are now looking into one of the toughest cancers to fight. However, scientists find repeated treatment of disease by drugs can actually lose its effectiveness over time as the cancer builds up resistance to the same treatment. This raises researchers' confidence that ginger would help stop resistance from the cancer. In a study, the cancer clearly stopped growing in the body of the mice that had been given ginger. The bad news is that such encouraging research has only been conducted on mice. The good news, however, is that it seems humans might be able to get the same benefit just by eating products with ginger and ginger root in them. Cancer prevention and fighting abilities aren't the only potential benefits you may get from adding a bit more ginger to your diet. Drinking ginger ale when your stomach was upset as a child wasn't just a placebo .Numerous studies and research, including the Mayo Clinic's strict grading system, agree that ginger has some sort of anti-nausea characteristics. Some believe that ginger works well against nausea after operations, while others use it to reduce motion sickness such as seasickness and car sickness. The Mayo Clinic, however, advises the use of ginger only to reduce nausea during pregnancy. While more research needs to be done, early studies are very promising, especially in that small amounts of ginger don't seem to do any harm to the mother or baby. Other health benefits from ginger exist as well. Since ginger is often considered to be useful in warming bodies, it can improve the condition of people's joints including knees and ankle joints. Some suggest that ginger can help cure a cough associated with the common cold. Another benefit of ginger is that it seems to have no real side effects, which is one of the main reasons it appears to be safe during pregnancy. But for safety, you should always consult a doctor for instructions on daily use before starting, even with something like ginger that seems to have little to no side effects.

mmlu_stem | mmlu_stem_8653 | Go, known as Weiqi in China and Baduk in South Korea, was viewed as the last game where humans can defeat machines. Lee Se-dol, one of the greatest Go players, has won 18 world championships for 21 years of his professional career. AlphaGo, a computer program developed by Google's DeepMind, beat the European Go champion, an achievement that was not expected for years in October, 2015. The match between Lee and AlphaGo was seen as a representative game between humans and Artificial Intelligence (AI). 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. Go originated from China more than 2,500 years ago. It involves two players who take turns putting markers on a net-shaped board to gain more areas on it. One can occupy the markers of the rival by surrounding the pieces of the other. Go is considered to be a lot more complex than chess where artificial intelligence scored its most famous victory to date when IBM's Deep Blue beat grandmaster Gary Kasparov in 1997. But experts say Go presents an entirely different challenge because of the game's incomputable number of move options. In other words, the computer must be capable of human-like "intuition" to win. "I was very surprised because I did not think that I would lose the game," said Mr. Lee.He said AlphaGo's early strategy was "excellent" and that he was shocked by one unconventional move it had made that a human never would have played, which he believed directly resulted in his loss. AlphaGo is proud of a deep learning capability to learn for itself and discover new strategies by playing games against itself and adjusting neural networks based on a trial-and-error process known as reinforcement learning. In spite of his loss, he did not regret accepting the challenge. "I had a lot of fun playing Go and I'm looking forward to the future games," he said after AlphaGo won 3-0 in a five-game match. "Playing against a machine is very different from an actual human player. Normally, you can sense your rival's breathing, their energy. And lots of times you make decisions which depend on the physical reactions of the person you're playing against. With a machine, you can't do that", Lee said. Which of the following is TRUE? | [

For a book of 21 poems, for example, I'll actually write about 50 poems first. Although I sometimes have images in my mind to go along with the words, I have to choose which ones I want to include in the book. TFK: Many of your books, including UnBEElievables, are about insects and animals. How did these become your favorite subjects? FLORIAN: There is so much humor in the animal world. People have a lot of knowledge about animals and ideas about animals that are fun to explore in writing. Animals are just so interesting. When I research, I find out so many new and amazing facts. The poem is often half written by the time I have done with my research. TFK: Why did you choose bees as the subject of your latest book? FLORIAN: I saw recently in the news that many bees are dying out. Scientists believe this to be caused by various diseases. I wanted to create awareness and learn more about bees after hearing this. So many of the fruits and vegetables we eat are dependent on pollination by honeybees. If bees disappear, so will much of our food. TFK: Do you have a favorite bee?

mmlu_stem | mmlu_stem_5553 | Paperback: 264 pages Publisher:. Sams (March 29,2005) ISBN: 0672327627 Product Dimensions: 8.4x5.5x0.6 inches OVERVIEW This book offers straightforward practical answers when you need fast results. By working through each 10-minute lesson, you'll learn what you need to begin to use the PHP scripting language to make your websites interactive and dynamic. REVIEW When I first laid eyes on this book and its title, Teach Yourself PHP in 10 minutes, my first thought was that I was going to see this! So I opened it up and figured I'd look through it for ten minutes and see what would hit me. Well, 10 minutes turned into 20, 20 into 30 and 30 into a valuable resource that sits on my desk. Not only are the lessons within brief, but they are very easy to understand, well presented and very easy to understand for the beginner. Each lesson comes with tips to point out shortcuts, cautions to help you avoid common mistakes and notes to additional infomation. This book can be used in two ways, as a reference or as a complete tutorial on PHP basics. That alone is something that is very rare in teaching type books these days. Some of the more valuable and informative lessons will take you into the areas of: --Strings and variables --Processing HTML forms --Controlling and filtering data --User authentication --Cookies and sessions --Security practices --Configuring PHP and more!!! The book is pretty basic for experienced PHP coders, but for new or intermediate users this book is worth more than the small $19.99 CAN suggested price. Although the cover suggests it covers PHP 5.0, the coding found within also applies to PHP 4.X CONCLUSION This book completely surprised me with its value and does indeed teach you in ten minutes what other books claim to do in 24 hours.

mmlu_stem | mmlu_stem_2823 | A British dog-lover has invented a high-tech way of feeding his pet by Twitter( ,). Computer expert Nat Morris ,30, has designed a system to give his pet a "tweet treat" by sending him a Twitter message. His dog Toby gets some delicious dog biscuits from a computer-controlled food machine whenever Nat sends a message to "@ feedtoby". Nat often works away from home and isn't always able to feed Toby by hand. But his new invention allows Nat to feed his dog from anywhere in the world. Nat said, "Toby ly loves it. At first he didn't know what was going on. Now he sits underneath the machine, wagging his tail and waiting for the food to drop." Nat fills the food machine with small pieces of dog biscuits, but not too many in case four-year-old Toby gets too many messages. And Nat has even equipped his house with an online camera so he can see Toby enjoying the food at his home. But one problem is that friends and family have been so amazed with the "tweet treat" machine that they have started sending tweets to Toby too. So Nat has had to restrict feeding time to make sure Toby doesn't turn into Tubby. "People have been sending him tweets at all hours of the day, so I had to limit it to between 9a.m. and 9 p.m. . I'm thinking of doing an updated one which can measure his weight before he is fed, just to make sure he's not putting on too much puppy fat," explained Nat. How Nat's Twitter Feeder works: When a message is sent to @ feedtoby, it is received by a mini -computer that is linked to the feed machine. When the mini-computer receives the message, a bell rings and Toby comes running over and sits in front of the feeding machine. Next, the machine's motor pulls open a trap door which releases a serving of food. The doggy biscuits then drop into Toby's food bowl. Finally a digital camera takes a photo of him and sends it back to Nat on Twitter -- so he knows Toby has been fed. In which section of the newspaper would you most probably find this passage? | [

mmlu_stem | mmlu_stem_7586 | Big trees are incredibly important ecologically. For a start, they provide food for countless other species and shelter for many animals. With their tall branches in the sun, they capture vast amounts of energy. This allows them to produce massive crops of fruit and flowers that sustain much of the animal life in the forest. Only a small number of tree species have the genetic ability to grow really big. The biggest are native to North America, but big trees grow all over the globe, from the tropics to the forests of the high latitudes . To achieve giant size, a tree needs three things: the right place to establish its seedling, good growing conditions and lots of time with low adult death rate. Lose any of these, and you will lose your biggest trees. In some parts of the world, populations of big trees are dwindling because their seedlings cannot survive. In southern India, for instance, an aggressive non-native bush, Lantana camara, is invading the floor of many forests. Lantana grows so thickly that young trees often fail to take root. With no young trees to replace them, it is only a matter of time before most of the big trees disappear. Without the right growing conditions, trees cannot get really big and there is some evidence to suggest tree growth could slow in a warmer world, particularly in environments that are already warm. Having worked for decades at La Selva Biological Station in Puerto Viejo de Sarapiqui, Costa Rica, David and Deborah Clark and colleagues have shown that tree growth there declines markedly in warmer years. "During the day, their growth shuts down when it gets too warm, and at night they consume more energy because their metabolic rate increases," explains David Clark. With less energy produced in warmer years and more being consumed just to survive, there is even less energy available for growth. The darks' theory, if correct, means tropical forests would shrink over time. The largest, oldest trees would progressively die off and tend not to be replaced. According to the Clarks, this might cause a destabilization of the climate; as older trees die, forests would release some of their stored carbon into the atmosphere, causing a cycle of further warming, forest shrinkage and carbon emissions. Besides, big trees face threats from elsewhere. All the following factors are a must for making big trees EXCEPT _ . | [

The quadruplets explained to The New York Times how they nervously logged on one by one to the Yale website to discover their fates, First was Ray, who described how the screen suddenly turned Yale blue and displayed the university's bulldog mascot with the message "welcome to the Class of 2014". "We just kept logging on and screaming, logging on and screaming,' Martina, last to find out, said in an interview with the local television station WINH-TV.

The 4D printing concept, which allows materials to "self-assemble " into 3D structures, was initially proposed by Massachusetts Institute of Technology faculty member Skylar Tibbits. Tibbits and his team combined a strand of plastic with a layer made out of "smart" material that could self-assemble in water. They advanced this concept by creating materials that can change into several different complicated shapes, though this kind of material remains the bottleneck of 4D technology. To many people that are just starting to get used to the idea of 3D printers, the name 4D is causing confusion because they cannot understand where this fourth "dimension" coming from. 4D technology shares many of the same principles of 3D printing and is essentially still about creating a new, 3D structure out of certain component; however, Tibbits states the fourth dimension at work here comes from concept of the fourth dimension of time. The difference between these 3D and 4D creations is that these new forms have the ability to transform and adapt over time. 4D printing works through self-assembly -- a system where "disordered elements form an "ordered" structure via an interaction. With these 4D printed materials, these disordered materials are strands or sheets of specially designed materials. Environmental changes then stimulate a response from them so that they form a preprogrammed shape. The idea of having adaptable technology that only relies on energy and non-human interactions raises some interesting questions about where 4D printing can be used and the practical applications in dangerous environments. This could mean improved infrastructures in extreme conditions, leading to a reduced need for workers to put themselves at risk, but the potential goes even further than that. The technology promises exciting new possibilities for a variety of applications. A solar panel or similar product could be produced in a flat shape onto which functional devices can be easily installed. It could then be changed to a compact shape for packing and shipping. After arriving at its destination, the product could be stimulated to form a different shape that serves its function. Also it could be used to build furniture, bikes, cars and even buildings. As with many of the ideas being put forward, it is easy to go a step too far into the extreme, but this just shows the potential of 4D in comparison to 3D. The next stage for the research is to move from printing single strands to sheets and eventually whole structures. And water need not be the process ' s only energy source. Which of the following displays the fourth dimension of 4D printing? | [
"4D printing creates a new, 3D structure out of certain component.",
"4D technology reduces need for workers to put themselves at risk.",
"4D technology can be used in many more fields than 3D printing.",
"4D printed materials reshape themselves with conditions changing."

mmlu_stem | mmlu_stem_10215 | There is a lot of talk these days about how kids should be interested in science. Here's an area of science for everyone, and these cool new books might inspire you to discover your inner scientist. Scaly Spotted Feathered Frilled by Catherine Thimmesh, 58 pages, ages 9-12 Seeing a picture or a model of a dinosaur, do you wonder how anybody knows what they look like? After all, nobody has seen a living dinosaur. This book explains how scientists and artists work together to re-create dinosaurs. As scientific discoveries have been made, the models have changed. Scientific tests may one day expose what a dinosaur's coloring was, but now artists have to use their imagination to determine how these huge creatures looked. Beyond the Solar System by Mary Kay Carson, 128 pages, ages 10-13 This book takes readers back to the beginnings of space exploration--thousands of years ago, when people began star observation--and forward to today's search for planets in distant parts of the Milky Way. Along with history lessons, readers get 21 activities, such as making a black hole and creating a model of Albert Einstein's universe using a T-shirt. The activities are perfect for cold winter days. Ultimate Bugopedia by Darlyne Murawski and Nancy Honovich, 272 pages, ages 7 and older If you're always on the lookout for butterflies, this book is for you. Hundreds of color photos of common and unusual insects fill this hardcover. There are fascinating stories related to the photos. For example, do you know an insect feeds on the tears of Asian cattle? There's a question-and-answer section with an insect scientist and advice on how to help preserve endangered insects. Journey Into the Invisible by Christine Schlitt, 80 pages, ages 9-12 If you use a magnifying glass, you know a leaf looks quite different. This book explains what microscopes do and then shows what happens to things around the house when watched with this amazing scientific tool. The bacteria in your mouth, when magnified 20,000 times, look a bit like swimming pool noodles. Fascinating photos are paired with suggestions about how to learn about the world around you, just by looking a little closer. From the passage, we can learn that _ . | [

mmlu_stem | mmlu_stem_7187 | Today, many people use plants from other places to design their yards. Well, do they have any influence on animals living nearby? As we know, plants supply food for things like insects and plant-eating animals. In turn, birds and meat-eating animals feed on these insects and plant-eating animals. It is easy to see how important plants are. Although foreign plants may look beautiful, they can cause problems when there are too many of them. I live in Virginia, USA, and sometimes see a plant--commonly known as Kudzu--that seems to cover everything in the area, even climbing over whole trees and houses. Kudzu is an unbelievable plant since it grows very fast. It was first brought to the United States from south-east Asia around the 1870's as a crop that farmers could grow. However, Kudzu quickly came to be considered harmful throughout the southern United States. Since Kudzu grows fast in many different environments, it can completely cover areas of land quickly. The plant is also not eaten by any insects or birds in the United States so it can grow unchecked. Kudzu can cover trees, bushes, and even houses. It costs the United States 500 million dollars a year to just keep Kudzu from growing too fast. The plant is a perfect example of what scientists call an invasive species, which grows more quickly than other native plants. All foreign plants have the possibility to spread quickly. Not only are they costly, but planting them in gardens actually takes away food from insects. If everyone filled their garden with plants native to where they live, many lovely butterflies and other native creatures would be attracted to their backyards! So, take a look out of your window -- how does your garden grow? How does the author sound when telling of these foreign plants? | [

mmlu_stem | mmlu_stem_11319 | What looks like a black hole, behaves like a black hole, but is bigger than a black hole? Two black holes! Astronomers last week discovered a pair of enormous black holes far out in the galaxy that appear to be dancing toward each other. However, astronomers say the collision is not likely to occur for several million years. Black holes are objects in outer space that are so dense that nothing can escape their gravity. They often sit in the center of a galaxy -- like the Milky Way --and suck up everything near them. The gravitational pull of a black hole is so intense that not even light (Which travels faster than anything else in space) can make it past without being swallowed. Black holes, like the one at the center of the Milky Way, are enormous. Scientists call some of them "supermassive", because they can be a few million times the size of most stars. Their size, their mass, and their inescapable gravity make black holes a giant force of nature in outer space. Because there is no light near black holes, astronomers cannot actually see them; they are completely invisible to us on the Earth. Scientists manage to detect the existence of a black hole by watching what happens to other objects, or matter floating in space. So how did scientists manage to get a good look at a region so faraway? The team used an orbiting NASA observatory known as Chandra. This special observatory uses X-rays rather than light to watch far out into space. Right before a star gets sucked into a black hole, it produces a large number of X-rays. Which of the following is NOT discussed in the passage? | [

mmlu_stem | mmlu_stem_3066 | According to a survey, only 4% of the people in the world are left-handed. Why? One theory centers on the two halves of the brain. For example, the left half and the right half, each of which functions differently. Medical science believes that the left half of the brain dominates over the right half. The foundation of this theory is the fact that nerves from the brain cross over at neck-level to the opposite side of the body, and nerves from the other side of the brain reciprocate . The end result is that the opposite sides of the body are controlled by the opposite sides of the brain. The dominant left half of the brain, which kindly supplies the right half of the body, theoretically makes it more skillful in reading, writing, speaking, and working, and makes most people right-handed. Lefties, however, whose right half of the brain dominates, work best with the left side of their bodies. Theory number two focuses on the _ nature of the body. Examples of the asymmetry, which flows from head to toe, are that the right side of our faces differs slightly from the left, that our legs differ in strength, or that our feet vary in size. One aspect of this asymmetry is that for most people the right hand is stronger than the left. There is no doubt that all exist in a "right-handed society", which produces most basics, including scissors, doorknobs, locks, screwdrivers, automobiles, buttons on clothing, and musical instruments for the 96%. Left-handed people make up for the unfairness by being members of an elite society, which includes many of the greatest geniuses, including Michelangelo and Leonardo da Vinci. What can be inferred from the passage? | [

They loved the river and soon began staying out all night on the river. Whenever I wanted to know where they were, I would make a honking noise , and they would answer me and come into the yard for their corn. One night, I was woken up by loud noise. We ran out to see what was wrong. A raccoon had decided that some goose eggs would taste good and had come too close to the setting.When we found Su, the raccoon had caught her by her neck and was biting it.We drove it away and took Su to the garage, washed her wound and wrapped it up in a bandage.Goose knew she was there and wanted to be with her, so we opened the small garage door and he hurried in.After two days and nights, I released them back outside. For the first three nights at dusk, we would get her and carry her into the garage for the night and Goose would come running behind us to join her there.We were touched by his devotion to her.We took off her bandage and she was fine so that next night, we had not planned to take her to the garage any longer.We were amazed, however, that when dusk fell that night, she climbed the back steps to our garage door waiting for us to come and get her in!

mmlu_stem | mmlu_stem_9768 | Many people have never heard of Mesothelioma and are unaware of its symptoms. Although considered a rare form of cancer, each year the number of cases grows. With the prevalence of this disease on the rise, it is critical to understand why and how Mesothelioma develops and what courses of action can be taken in the event of diagnosis. The following is a list of frequently asked questions and answers that will provide you with some information on Mesothelioma, and the legal issues surrounding it. What is Mesothelioma? Mesothelioma is the term used to describe a cancerous tumor found in the mesothelial cells of an organ. The organs where this form of cancer is most commonly found are the lungs, heart and abdominal organs. Pleural Mesothelioma is cancer of the lung lining(,)and is the most common form of Mesothelioma. What causes Mesothelioma? Mesothelioma is almost always caused by exposure to asbestos . Asbestos is often found in building materials used before the mid 1970's. In addition, materials such as pipes, boiler insulation, floor, ceiling and roof tiles may contain asbestos. How much asbestos exposure will cause Mesothelioma? Generally, the probability of developing this form of cancer is in accordance with the length of time you are exposed to asbestos. Also, your health is at risk if your exposure to asbestos is intense. It should be noted that Mesothelioma has a latency period of 20 to 50 years. This means that you may develop the disease long after your exposure to asbestos. On average, people tend to develop Mesothelioma somewhere between 35 and 40 years after exposure. How quickly does Mesothelioma progress? The onset of Mesothelioma is quite slow. Patients will begin to experience symptoms such as lower back pain and chest pain. These symptoms may also be accompanied by weight loss, fever and difficulty breathing. Unfortunately, once Mesothelioma develops, it quickly becomes aggressive and treatment must be sought immediately. Can Mesothelioma be treated? Doctors are able to use several traditional methods of cancer treatment for Mesothelioma, including surgery, chemotherapy and radiation. Like all forms of cancer, detecting the disease at the earliest stage possible greatly increases the patient's chances for survival. If you have worked in an industry such as construction or suspect that you may have been exposed to asbestos, be alert for symptoms and contact your doctor immediately. What legal courses of action can be taken? Anyone suffering from Mesothelioma is entitled to compensation from asbestos manufacturers. Additionally, if you are the spouse or child of someone who has died from Mesothelioma, you are entitled to file a claim and seek compensation.

mmlu_stem | mmlu_stem_11574 | For thousands of years, people thought of glass as something beautiful to look at. Only recently have they come to think of it as something to look through. Stores display their goods in large glass windows. Glass bottles and jars that hold food and drink allow us to see the contents. Glass is used to make eyeglasses, microscopes, telescopes, and many other extremely useful and necessary objects. Until the Second World War, most of the glass used for optical instruments was imported from Europe. However, during the war Americans could not get European glass, and they were forced to make their own. Therefore, new kinds of glasses were developed that had been previously unknown. These new effects were achieved by mixing other chemical elements with the sand. Some of these new glasses are very strong and can resist many kinds of shocks. Legend has it that a very hard glass was invented by a Roman who showed his discovery to the Emperor. When the Emperor saw the glass he feared that it would become more valuable than gold and sliver, making his treasure worthless. Therefore, he had the glassmaker killed, and the secret was not discovered again for hundreds of years. In the present century, safety glass was invented for use in modern cars and planes. Safety glass is made by placing a layer of plastic between two layers of plate glass. When the outside layer of glass is broken, the pieces do not scatter and injure people. Some glass of the type is strong enough to resist bullets . Although nowadays plastics have replaced glass under conditions where glass might be easily broken, there are new uses being developed, for the greatest advantage of glass is that its component parts are inexpensive and can be found all over the world. As time goes by, glass _ . | [

Mushroom growing is becoming more and more common as restaurants are creating more dishes that include mushrooms. Mushroom growing is easy. To start with you need to have a growing space where you are going to grow these mushrooms. It does not have to be too big enough for you to grow as many mushrooms as you need. When you have found the space that is perfect for you, you can start to research what kind of mushrooms you want to grow. There are hundreds of kinds to choose from but not all mushrooms are _ which is an important fact you need to remember before you start. Don't grow mushrooms you can't use or sell. When you figure out what kind of mushrooms you want to grow, you can make some preparations. Sometimes you need to hire some workers to help you if you have a large mushroom farm, or if you are trying to start a professional mushroom growing business. Trying to start a business by yourself can be stressful. If you don't have time to take care of everything yourself, to hire a worker is the best bet. After you have started the mushroom growing, you should regularly check and make sure that your mushrooms are growing properly and that they are not being attacked by any pesticides or any other animals that are potentially dangerous for them. That is the worst situation of mushroom growing. Protect your mushroom farm well with a fence or a gate so that only you and your workers can get in an out.

mmlu_stem | mmlu_stem_6844 | Here in Alaska, the wolf almost disappeared a few years ago, because hunters were killing hundreds of them for sport. However, laws were passed to protect the wolves from sportsmen and people who catch the animals for their fur. So the wolf population has greatly increased. Now there are so many wolves that they are destroying their own food supply. A wolf naturally lives on animals in the deer family. People there also hunt deer for food. Many of the animals have been destroyed by the very cold winters recently and by changes in the plant life there. When the deer can't find enough food, they die. If the wolves continue to kill large numbers of deer, the deer will disappear some day. And the wolves will, too. So we must change the life cycles there. If we killed more wolves, we would save them from starving. We also save deer and some farm animals. In another northern state, wolves attack cows and chickens for food.

This is not true. There is no man in the moon. What do we know about the moon? First of all, the moon is much smaller than the earth. Days and nights on the moon are very long. One day on the moon is as long as two weeks on the earth. One night is also as long as two weeks on the earth. In the daytime the moon is very hot and at night is very cold. Now we know _ . | [

mmlu_stem | mmlu_stem_13854 | Many animals go on long and difficult journeys to find food or places for their young to start life. They often travel very far, sometimes even halfway around the world. Some animals make one of these amazing journeys every year, while others make only one amazing journey in their lives. Some animals travel over land, some through water and others in the air. Green turtles spend most of their lives in the sea, but they come to the shore to lay their eggs. Every two or three years, fully-grown female turtles swim a long way to the same beach where they were hatched and lay their eggs there. Some turtles may travel over 1240 miles to reach the same beach. No one knows how these turtles are able to find the same beach again. Monarch butterflies live in North America. At the end of summer, they fly south to Mexico. In spring, they fly back north. During this journey, the adults lay their eggs and then they die. When the young butterflies hatch, they continue the journey north. No one knows how the young butterflies know where to go. Monarch butterflies lay eggs _ . | [

mmlu_stem | mmlu_stem_15734 | Most middle school students find it boring to learn English. But students in Yat Sen middle school in New York, US, don't think so. Why? Because they are in the school of One Program, which asks students to work on their own or in small groups on computers to have math lessons. "The program gives the students a new learning style. No traditional classroom can compare with it. We give each lesson according to the students' interest and their strong and weak points," said JoelI. Klein, the school's head teacher, "we're looking for a new way that interest students children." Students enjoy these math lessons, especially lessons with video games. They must find out the answers to math problems to get through the game. One such game is Dimension M. As students move through mazes with their keyboards, some questions come up. Caleb Deng had to answer the question: What is 5+ (6x3)? He _ on paper quickly because there was just a minute left to play. " I was right," said Deng, 14, as he ended the game with a high score .

mmlu_stem | mmlu_stem_4132 | "Hey, don't read in the hallway. Your eyesight will be damaged." You must have heard such warnings many times. Don't read in dim light! This is one of the "pearls of wisdom" that are supposed to help us live a healthy life. Such common beliefs, however, lack scientific basis, according to a paper published recently in theBritish Medical Journal. Do you believe in the following everyday wisdom? Reading in dim light ruins your eyesight. In dim light, you might blink more, feel discomfort from drying and have trouble focusing. But the majority of eye experts believe it is unlikely to do any permanent damage. We must drink at least eight glasses of water a day In 1945, the Nutrition Council in US suggested that people need to consume 2.5 litres of water a day. But the water contained in food, particularly fruit and vegetables, as well as in milk, juice and soft drinks, also counts towards the total. We only use 10 percent of our brains. This myth arose as early as 1907. People have long argued about our power of self-improvement and our brains' potential abilities. But detailed imaging shows that no area of the brain is silent or inactive. Shaving your legs causes hair to grow black faster and thicker. This theory is also illusion. Shaving has no effect on the thickness or rate of hair growth, studies say. Just over time, the edge of hair gets worn away and thus the edge of long hair becomes finer . So hair that is newly grown gives the impression of darkness. What does the paper say about some common beliefs? | [

mmlu_stem | mmlu_stem_8368 | As they migrate , butterflies and moths choose the winds they want to fly with, and they change their body positions if they start floating in the wrong direction. This new finding suggests that insects may employ some of the same methods that birds use for traveling long distances. Scientists have long thought that insects were simply at the mercy of the wind. Fascinating as their skills of flight are, migrating behavior has been difficult to study in insects because many long distant trips happen thousands of feet above ground. Only recently have scientists developed technologies that can detect such little creatures at such great heights. To their surprise, though, the insects weren't passive travelers on the winds. In autumn, for example, most light winds blew from the east, but the insects somehow sought out ones that carried them south and they positioned themselves to navigate directly to their wintering homes. Even in the spring, when most winds flowed northward, the insects didn't always go with the flow. If breezes weren't blowing in the exact direction they wanted to go, the insects changed their body positions to compensate . Many migrating birds do the same thing. The study also found, butterflies and moths actively flew within the air streams that pushed them along. By adding flight speeds to wind speeds, the scientists calculated that butterflies and moths can travel as fast as 100 kilometers an hour. The findings may have real-world applications. With climate warming, migrating insects are growing in number. Knowing how and when these pests move could help when farmers decide when to spray their crops. We can learn from the text that _ . | [

mmlu_stem | mmlu_stem_9933 | Some wonderfully creative uses of X-rays have been in the world of art.But the most impressive one is to uncover what has been covered up.Details unfolded by an X-ray of a painting can ' t be seen any other way.For example, in the past, paintings were often repaired if small pieces of paint fell off the canvas . These repairs cannot be seen just by looking at the painting.It takes an X-ray to discover where the repairs have been made. An X-ray of a painting is one of the best ways to tell if it was created by a famous painter or if it is a forgery .If there is a question as to whether an old master has painted a certain painting or not, X-rays are made and compared to those of paintings that are known to be original.If the brushstrokes , for example, are shown to be totally different than in other work done by a certain artist, then the painting is proved to be a fake copy. Since modern paints are usually made from different materials than paints of hundreds of years ago, the image they leave on an X-ray film looks different.This is another way X-rays can be used to spot a forgery.A modem artist will try to make a forgery look hundreds of years old by painting dirty varnish on it or by using artificial means to get the varnish to look cracked.To the naked eye the forgery may look old, but when a careful study of the X-ray image is made, the _ is obvious. It was common many years ago for an artist to finish a painting, decide it wasn't any good, and paint a completely different picture on top of it.Or artists would paint over others' work --it was their version of recycling.Taking an X-ray is the only way to find out if there is a picture underneath the picture you see with your eyes.Sometimes museums will be more interested in the painting beneath than the one on top, and will restore the older one by having the top layer painstakingly removed.

mmlu_stem | mmlu_stem_8725 | A dog's tail can tell you a lot more than you might think. Is it wagging to the left or is it wagging to the right? "The direction of tail wagging does in fact matter,"said Giorgio Vallortigara,a professor at the University of Trento in Italy. Professor Vallortigara finds that the way the tail is wagging can tell you a lot about a dog's state of mind--whether you're a human or another dog. What's the difference between a left wag and a right wag?Professor Vallortigara and his colleagues have studied 43 dogs of various breeds -- German Shepherds,Beagles,Boxers,Border Collies and some mutts. They find that if a dog wags its tail to the left. it's feeling anxious or nervous. The reason could be an unfamiliar or dangerous situation,an unfamiliar person,or an unfamiliar and possibly threatening dog. But if the tail is wagging to the right,it means the dog is feeling relaxed and approachable. "The tail is a very important signal,"said Thomas Reimchen,a biologist at the University of Victoria in British Columbia, Canada. "There is a lot of visual information that dogs use when communicating with each other. " How did the scientists figure all this information out? They had the dogs in their study watch videotapes of other dogs. When the dog on the tape wagged its tail to the right,they say the other dogs remained calm and cool. But when the dog on the tape wagged its tail to the left,the other dogs got anxious. The researchers are still not exactly sure if the direction of tail wagging is something the dog does consciously. They suspect that it might be something the dog does without even thinking about it -- kind of like when you get goose bumps if something scares or startles you. They plan to do more research to get more information about what dogs are thinking and feeling while they're wagging. As Reimchen said,"I'm not going to be surprised if we find all sorts of really interesting processes that nobody has ever seen before.

mmlu_stem | mmlu_stem_7749 | When a person travels over long distances, the place may not be the only change. When his or her body rhythms get thrown off, he or she suffers from jet lag -- it's hard to sleep and eat at the right times in the new location. Humans and animals have a biological clock in their body that tells them when to sleep, and when to wake. When someone comes to a different place far away, this biological clock takes a while to match the day and night time of the new place. In a new study, reported in November's Science News, researchers at the University of California, Berkeley tested the effects of jet lag on hamsters . They wanted to know how serious jet lag would affect the brain and thinking habits of the animals. They think what happens to hamsters may happen to humans, too. In their experiments, the researchers first moved the hamsters' schedules forward by six hours. The animals' eating schedules, for example, were changed. If a hamster was often fed at noon and 4 pm, then it ate at 6 pm and 10 pm on the new schedule. People who travel from China to Europe experience the same shift, since the two regions are about six hours apart, half the shift between China and the USA. After three days, the scientists did it again - they shifted the hamsters' schedules forward by another six hours. Three days after that, they did it again; and then again three days later. For a full month, the scientists changed the hamsters' routines every three days. During the study, the hamsters slept the same amount every day as they did before the study. However, their sleep patterns had a hard time keeping up with the changing schedule. What's more, they seemed to feel low. The researchers also found that the hamsters had trouble with basic learning exercises during the study. The animals' thinking problems didn't go away when the experiment was over. A month after they went back living on a normal schedule, the hamsters still had trouble with basic mental tasks, such as learning and memory. The scientists concluded that serious jet lag has serious side effects, including stupidity . They are now trying to find out how jet lag is causing these problems, and then it will be possible for them to work out a solution. Which of the following was NOT a true effect of jet lag on hamsters according to the text? | [
"They got a weaker memory.",
"They were in low spirits.",
