mmlu_train_35192 | When we hear of dangerous diseases, cancer and heart disease are often what first comes to mind. Recently, a virus called Ebola has reappeared in Guinea (a country in West Africa), killing 62 people so far. It leads to viral hemorrhagic fever, which is characterized by high fever and internal bleeding etc, Ebola can kill 90% of those infected, especially in underdeveloped societies like those in Africa. Ebola is named after the Ebola River, where it was first discovered in 1976. There are five different types of the Ebola virus, each named after where they first happened: Sudan, Ivory Coast, Restoon, Bundibugyo, and Zaire. The deadliest of the five, Zaire, was responsible for the 2012 outbreak, and is believed to be attacking Guinea. Ebola is naturally found in fruit bats , which pass on the virus to other animals by biting or sucking on their blood. Humans who are suffering from the Ebola infection might have touched the bodily fluids of the infected animals. Once infected, a human becomes a carrier of the deadly virus. Since we live in an interconnected world, where the situation in one country can affect us all, the influences of Ebola are huge: damaging trade relations, affecting foreign visitors, and weakening entire countries. Already the Guinea virus is spreading fast with a few cases spotted in Conakry -- the capital of Guinea, far away from the origin of the virus. It is feared that the disease may have already reached neighboring Liberia and Sierra Leone, too. Unfortunately, there are no disease-specific treatments for Ebola. Healthcare workers only supply the infected people with water to keep them in good condition. Since there have been many cases of nurses catching the disease from patients, they are forced to wear strict protective clothes, and in some cases, not even allowed to get close to the affected. The fact that there is no cure for the Ebola virus is what makes the outbreak a challenging one to control. What can we learn about Ebola? | [

mmlu_train_52365 | Getting sick overseas can be scary. You're in an unfamiliar place and often don't speak the language. Although each trip is different, there are universal things you can do to keep safe. Be prepared. "Schedule a visit with a doctor who specializes in travel or the area you're visiting at least four weeks before your departure," says WHO public health expert Dr. Gilles Poumerol. A travel doctor will be able to give you the required and recommended vaccinations as well as discuss any medical issues you may come across abroad. Get insurance. "In many countries where you have limited access to health care, good health care is only found in the private sector and can be very expensive," Dr. Poumerol says. Plus, in an emergency, returning to the United States can cost more than $50,000. Ask your health insurance company whether your policy applies overseas and whether it will cover trips to a foreign hospital. If not, there are many companies that offer short-term travel health insurance for a reasonable fee. A list can be found on the US State Department's travel website. Ks5u Pack well. Dr. Poumerol also suggests bringing a note from your doctor in English and the language of the country you're visiting. Packing an emergency contact list is important. Contacts should include the local embassy , s who should be informed if you get sick and your health insurance company. Be care. You have to be in charge of your health. If you're being treated abroad, question the medical staff about their sterilization practices; injection equipment should be put in boiling water for at least 30 minutes or used only once. Also be sure that doctors and nurses are wearing gloves to prevent fluid transfer. Limiting your alcohol intake will keep you focused on your safety. If your common sense is perfect, the rest of your body should follow. What is the best title for this passage? | [

mmlu_train_31152 | It takes years of school to develop math skills, but learning about numbers starts earlier than you might think. Now according to a new study, at three months, babies have already started acquiring a concept of "how much". Previous research had suggested that very young babies can tell when the number of objects in a group has changed. But the babies in these studies were simply reacting generally to the fact that something had changed, they suspected. Researchers of Harvard University studied 36 babies, all three months old. During the tests, each baby wore a hat with sensors . The babies watched a series of images on a computer screen. _ showed the same object, such as a cartoon character. For a while, the number of the objects in the pictures didn't change. Then the images began to display a different object, or a different number of one of the objects the babies had previously looked at. As soon as something changed, the babies' brains responded with a specific pattern of electrical signals, which would be recorded by sensors. By analyzing these signals, the researchers discovered that one part of the brain (near the top on the left side) responded when the object in the image changed. A different part of the brain (lower and on the right side) responded when the number of objects in the image changed. This was not the area of the brain that is involved in attention. That suggests that the babies' brains are doing more than just reacting to a change in what they're seeing - they actually seem to be able to tell number changes from other types of changes. Numbers and amounts are important concepts in our lives. Even though babies are years away from adding, subtracting , multiplying, and dividing, their brains seem to be preparing for a time when they finally will. The purpose of the study is to prove that _ . | [

mmlu_train_27261 | Something in chocolate could be used to stop coughs and lead to more effective medicines, say UK researchers. Their study found that theobromine , found in cocoa, was nearly a third more effective in stopping coughs than codeine, which was considered the best cough medicine at present. The Imperial College London researchers who published their results online said the discovery could lead to more effective cough treatment. "While coughing is not necessarily harmful it can have a major effect on the quality of life, and this discovery could be a huge step forward in treating this problem," said Professor Peter Barnes. Ten healthy volunteers were given theobromine, codeine or placebo, a pill that contains no medicine, during the experiment. Neither the volunteers nor the researchers knew who received which pill. The researchers then measured levels of capsaicin, which is used in research to cause coughing and as a sign of how well the medicines are stopping coughs. The team found that, when the volunteers were given theobromine, the capsaicin needed to produce a cough was around a third higher than in the placebo group. When they were given codeine they needed only slightly higher levers of capsaicin to cause a cough compared with the placebo. The researchers said that theobromine worked by keeping down a nerve activity , which cause coughing. They also found that unlike some standard cough treatments, theobromine caused no side effects such as sleepiness. What was used in the experiment to cause coughing? | [

mmlu_train_44347 | Spending just a few hours a week online may make people feel more socially isolated , lonely and downhearted , according to a two-year study of nearly 100 families with the Internet. "We were surprised to find that social technology has such bad effects on social communications," the lead author, Dr. Robert Kraut of Carnegie Mellon University in Pittsburgh, Pennsylvania, said in a statement to the news. The findings suggest that "Rather than encourage students to use the Internet alone for research, teachers might give pupils online group homework to complete with classmates. Local groups might build websites that allow neighbors to discuss local affairs ." "Before the technology develops and can be really more _ , people shouldcontrol their wishes to use much of the Internet," Dr. Kraut and other experts advise. In order to control their children and encourage family activities, parents might think of putting the computer in the living room rather than in a child's room, they suggest.

mmlu_train_51537 | Electricity, like clean water, is a resource that's often taken for granted. But last summer, when blackouts struck much of the northeastern US, Ontario and Rome, consumers on two continents were given a painful reminder of just how easily broken electricity supplies can be. The massive disorder stranded commuters, stopped freezers, shut down businesses and refocused attention on where most of the planet's power comes from:oil-and-gas-fired generators and nuclear plants, These sources not only pollute the environment but also make many consumers feel unacceptable health risks. Companies are trying to offer an alternative, clean energy from renewable resources that's plentiful and portable. Lifton's Medis Technologies, as well as companies like Hydrogenics and Nanosys, is tapping into fuel cells and dolor panels to give people power whenever and wherever they want it, free from dependence on local grids . The search for alternative energy is nothing new, but the current trend of innovators is focusing on the goal of making clean and sustainable power a mainstream commodity. For example, the fuel cell, which produces electricity from the chemical reaction between oxygen and hydrogen, has been around for about 150 years, though its commercial development did not begin until the 1960s and then only as part of NASA spacecraft. Today this technology is coming down to Earth in places like Tokyo; in nine European cities, from Stockholm to Porto, each operating three hydrogen-fuel-cell buses; and in Iceland, which is trying to create the first fuel free hydrogen economy by 2030. When hydrogen and oxygen molecules combine, the reaction produces heat and water. Fuel cells use this reaction to generate electricity. With the cell phone and gadget market in mind, Medis has developed a fuel cell with cheap components that produces little heat and effortlessly reduces waste water without turning to energy consuming pumps. Which of the following statements is NOT true according to the passage? | [
"Lifton's Medis Technologies is tapping into fuel cells and solar panels.",
"The fuel cell has been around for about 150 years.",
"The fuel cell's commercial development did not begin until the 1960s.",

mmlu_train_67508 | Millions of stars are travelling about in space. A few form groups which travel together, but most of them travel alone. And they travel through a universe which is so large that one star seldom comes near to another. For the most important part each star makes its journey in complete loneliness, like a ship on an empty ocean. The ship will be well over a million miles from its nearest neighbour. From this it is easy to understand why a star seldom finds another anywhere near it. We believe, however, that some two thousand million years ago, another star wandering through space, happened to come near our sun just as the sun and the moon raised its tides on the earth, so this star must have raised tides on the surface of the sun. But they were very different from the small tides that are raised in our oceans; A large tidal wave must have travelled over the surface of the sun, at last forming a mountain so high that we cannot imagine it. As the cause of the disturbance came nearer, so the mountain rose higher and higher. And before the star began to move away again, its tidal pull had become so powerful that this mountain was torn to pieces and thrown off small parts of itself into space. These small pieces have been going round the sun ever since. They are the planets. The expression "the cause of the disturbance" refers to _ . | [

Perhaps he sent you to a hospital, but all the advanced equipment there shows that there is nothing wrong with you. Then, consider this: you might be in a state of subhealth. Subhealth, also called the third state or gray state, is explained as a borderline state between health and disease. According to the study by the National Health Organization, over 45 percent of subhealthy people are middle-aged or elderly. The percentage is even higher among people who work in management position as well as students around exam time. Symptoms include a lack of energy, depression, slow reactions, sleeplessness, anxiety, and poor memory. Other symptoms include shortness of breath, sweating and aching in the waist and legs. The key to preventing and recovering from subhealth, according to some medical experts, is to form good living habits, alternately work with rest, exercise regularly, and take part in open air activities. As for meals, people are advised to eat less salt and sugar. They should eat more fresh vegetables, fruits and fish because they are rich in nutritional elements-vitamins and trace elements that are important to the body.

In addition, rubber, motor oil and other materials accumulate on roadways and are washed into streams, with effects nearly as serious as those of untreated waste water. In an effort to improve the situation, the U.S. government has made regulations on the use of the constituents of automobile exhaust gas that are known to cause air pollution. These constituents fall roughly into three types: hydrocarbons that pass through the engine unburned; carbon monoxide, also a product of incomplete burning; and nitrogen oxides which are formed when nitrogen and oxygen are in contact at high temperatures. Besides their own poisonous character, hydrocarbons and nitrogen oxides react in the presence of sunlight to form harmful smog. Carbon monoxide and hydrocarbons are rather easily controlled by the use of higher burning temperatures in engines. Unfortunately, the conditions that produce minimum emission of hydrocarbons tend to raise emission of nitrogen oxides. In a way this difficulty is solved by adding recycled exhaust gas to the fuel mixture, thus avoiding the oversupply of oxygen that favors formation of nitrogen oxides. California, which has the most strict air-pollution laws in the United States, requires further special compounding of gas to control emissions, and several states have ordered that alcohol be mixed with gas, as this will reduce emissions of the carbon monoxide by 35 per cent and the hydrocarbons by 15 per cent.

mmlu_train_39543 | There are robots all around us. Some do very complicated jobs like flying airplanes and driving subway trains. and some do one simple job. When an automatic washing machine is switched on, water pours in. The machine waits until the water is warm enough for washing clothes. It does this by "feedback" . Information about what is happening is feedback into the robot to tell what to do next. Our eyes, ears and other senses are our feedback. They tell us what is going on around us. So robots are like human beings in two ways. They work and they have feedback. In some ways robots are better than human beings. They work quickly and do not make mistakes. They do not get bored doing the same job over and over again. And they never get tired. So robots are very useful in factories. They can be taught to do many different jobs. First their electronic brain must be shown how the job is done. A person moves the robot's "arms" and "hands" through each part of the job. The most intelligent robots can move and see. Their eyes are cameras. Their fingers can feel shapes and sizes of the objects. These robots have computer brains linked to their eyes and fingers, which control their actions.

mmlu_train_25742 | In tests, it shrank breast tumours by 80 percent and researchers believe it could also treat prostate, pancreatic, bowel and ovarian cancers. Even tumours that resist treatment with the best medicines on the market, including the "wonder drug" Herceptin, may surrender to the vaccine. The experiments so far have been on mice - but researchers hope to pilot the drug on people within two years. If all goes well, the vaccine could be on the market by 2020. Rather than attacking cancer cells, like many drugs, the new treatment arouses the power of the immune system to fight tumours. The search for vaccines has been prevented by fears that healthy tissue would be destroyed along with tumours. Researchers from the University of Georgia and the Mayo Clinic in the US focused on a protein called MUC1 that is made in bigger amounts in cancerous cells than in healthy ones.Not only is there more of it, but a sugar that it is "decorated" with has a distinctive shape. The vaccine trains the immune system to recognise the rogue sugar and turn its weapons against the cancer. "Cancer cells have a special way of thwarting the immune system by putting sugars on the surface of tumour cells so they can travel around the body without being detected," researcher Professor Sandra Gendler said. "To enable the immune system to recognise the sugar it took a special vaccine that had three parts to it. "She said it was this that "turned out to be a winning combination".

mmlu_train_19290 | Introductory Chemistry was taught at Duke University for many years by professor Bonk. One year, two guys took the class and did pretty well on all the quizzes and mid-terms. They each had a solid A. These two friends were so confident in going into the final that the weekend before finals week, despite the Chemistry final being on Monday, they decided to go to the University of Virginia to party with some friends. They had a great time there. However, with their hangovers and tiredness, they overslept all day Sunday and didn't make it back to Duke until early Monday morning. Rather than taking the final then, they found professor Bonk after the final and explained to him how they missed the final. They told him they went up to the University of Virginia for the weekend and had planned to come back in time to study, but they had a flat tire on the way back and didn't have a spare. So they were late getting back to campus. Bonk thought this over and agreed that they could take the final the following day. The two guys, happy and relieved, studied that night and went in the next day at the time that Bonk had told them. He placed them in separate rooms and handed each of them a test booklet. He told them to begin. They looked at the first problem which was something simple about solution . It was worth 5 points. "Cool," they thought, "this is going to be an easy final".

When water freezes and turns to ice,it expands .The force of water expanding is so great that it will break the hardest metal.Water is used in car engines to keep them cool while they run,and if this water is allowed to freeze in winter it can break the iron block of the engine.That is why antifreeze is necessary. Water freezes at 0degC;the usual kind of antifreeze will not freeze until the temperature is-40degC.A mixture of five parts of water and four parts of antifreeze will prevent freezing at-18degC;four parts of water and five parts of antifreeze reduce this to -22degC. Alcohol is a kind of good antifreeze,but when the air is running it becomes hot and the alcohol boils away,so it must be changed very often.Most people use antifreeze that does not boil away when the engine is running.There are several chemicals that do this.One of the most popular is called ethylene glycol.

mmlu_train_55968 | There are three different ways to store fish. Two ways to store fish for future use are canning and freezing. Two other methods are drying and smoking. Today we have the first of the two reports describing, step by step, how to prepare dried fish. Begin with the fish that are just out of water. If the fish are small, leave their heads on. Cut off the heads if the fish are longer than twenty centimeters or weigh more than one hundred fifteen grams. Now clean the freshly caught fish. Cut off the scales and cut open the stomach. Remove everything inside. Then wash the fish in clean water and rub salt into them. Next, put the fish in a container with a solution of three hundred grams of salt and one liter of water. This will remove the blood from the meat. Keep the fish in the salt water for about thirty minutes. After that, wash them again in clean water. Next, put the fish in a solution that has more salt in the water. The water should be salty enough so that the fish float to the top. If the fish sink to the bottom of the container, add more salt to the water. Cover the container with a clean piece of wood. Place a heavy stone on the wood to hold it down. Leave the fish there for about six hours. After that remove them from the salt water and place them on a clean surface. Cover the fish with a clean piece of white cloth and let them dry. Another method of preparing fish is called dry salting. Wooden boxes or baskets are used for drying salting. After cleaning the fish, put a few of them on the bottom of the box or basket. Cover them with salt, then put more fish on top. Cover them also with salt. Continuing putting fish and salt in the container until it is full. Do not use too much salt when using the dry salting method. You should use one part salt to three parts fish. For example, if you have three kilograms of fish, you should use one kilogram of salt. Remove the fish after a week or ten days. Wash them in a mixture of water or a small amount of salt and let them dry. We have talked a lot about salt. keep in mind that doctors advise people to limit the sodium in their diet. It can raise blood pressure, and some people have more of a reaction than others.

In the United States today, laptops also connect students to their classrooms. Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the 1500 students at the college will receive a laptop. The laptops are part of a $10 million computer program at Westlake, a 110-year-old college. The students with laptops will also have access to the Internet. In addition, they will be able to use e-mail to "speak" with their teachers, their classmates, and their families. However, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast-food restaurant or under the trees----anywhere at all! Because of the many changes in computer technology , laptop use in higher education, such as colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers. In addition, the portable computers can connect students to not only the Internet, but also libraries and other resources. State higher-education officials are studying how laptops can help students. State officials are also testing laptop programs at other universities, too. At Westlake College, more than 60 percent of the staff use computers. The laptops will allow all teachers to use computers in their lessons. As one Westlake teacher said, " Here we are in the middle of Virginia and we're giving students _ .

mmlu_train_24045 | American researchers say drinking tea may help strengthen the body's defense system against infection. Doctors at Brigham and Women's Hospital in Boston, Massachusetts, did the study. The team studied a chemical found in black, green, oolong and pekoe tea. This chemical is an amino acid called L-theanine. The scientists say it may increase the strength of gamma delta T cells. That's the letter T, not the drink. Gamma delta T cells are part of the body's defense. First, the researchers mixed some of these cells with antigens found in the amino acid . Antigens help the body react to infection. Then the scientists added some bacteria. Within twenty-four hours, the cells produced a lot of interferon, a substance that fights infection. Cells not mixed with the antigens did not produce interferon. In the second part of the study, eleven people drank five to six cups of black tea every day. Ten other people drank the same amount of instant coffee. That is dried coffee mixed with hot water. Two weeks later, and again two weeks after that, the researchers tested the blood of all twenty-one people. They also looked at what happened when they added bacteria to the blood cells. They found that the tea drinkers produced five times more interferon after they started drinking tea. The coffee drinkers did not produce interferon. Doctor Jack Bukowski led the study. He says the antigens added to the gamma delta T cells were responsible for the increased reaction to the bacteria. He says that the study also showed that the cells were able to remember the bacteria and fight them again the next time. Earlier research already has found that tea can help prevent heart disease and cancer. Doctor Bukowski says the new study must be repeated by more people. "If the findings prove to be true," he says, "then tea drinking might also help protect against bacterial infections." He says the amino acid L-theanine could be removed from the tea and used as a drug to strengthen the body's defenses. Tea may help strengthen the body's defense system because it helps _ . | [

mmlu_train_54234 | Many people feel that their parents were harder on them than on their brother or sister. And many are quick to blame negative results in adulthood on it. But results from a Temple University study published this month suggest that it is not necessarily true. Researchers have found that among siblings in the same family,recalled negative early experiences such as conflicts with parents seem to have little influence over psychological wellbeing in midlife. "Existing research suggests the importance of early childhood parental treatment on later wellbeing,but respondents in this study who thought they were treated less favorably than their siblings have been found to be just as satisfied in their lives,"said Adam Davey,a psychologist in the College of Health Professions. Davey's study looked at data collected from 1,369 siblings between the ages of 26--74 from 498 different families to determine the extent to which different childhood treatment reached into adulthood. Each sibling answered a series of questions about their memories of parental affection ,conflicts with their parents when they were young and current wellbeing. Davey and his team found that those who remembered having more conflicts with their parents than their siblings still tended to have generally high levels of wellbeing in adulthood. Not surprisingly,they also found that happier memories,such as memories of affection and warmth,can have positive effects. Older respondents who were married and had children of their own tended to have a more positive recollection of their childhood. Davey says these findings could suggest that life experience acts as a filter for remembering childhood memories. He adds that personality also plays a role:those who were more outgoing tended to have a better recollection of their childhood. "Even people who grow up in the same environment can have different ways of recalling the past. And it's not necessarily what happens in the past,but the way we remember it that makes a difference to our wellbeing,"said Davey. What's the purpose of the passage? | [

mmlu_train_14859 | Worried about how many calories( ) you are going to get in that piece of pizza, chocolate cake or bag of chips? A new iPhone application that takes a picture of the meal with the phone and gives a calorie read-out almost at once, may help. The MealSnap was developed by DailyBurn, a fitness social network that has created several other fitness and diet-related iPhone applications. Within minutes of taking a picture of a meal and matching it to the given information of some 500, 000 kinds of food, the application sends users a warning with a range of calories for the meal that was photographed. To start with, we sent it something simple--a Braeburn apple. A couple of minutes later the application replied that it was between 64 and 96 calories. Andy Smith, chief director at DailyBurn, said: "The database can also quickly help recognize the food, how many calories there are, proteins, fat, carbs, vitamins, whatever you may want to know." Mr Smith added that it will take some time to complete calorie counting but the application makes it easier to record the calories in food. That is why it is so popular among those who are trying hard to lose weight. "The pure act of recording something can cause a psychological change that can help people on their health and fitness plan. Just the simple fact of recording it makes me more understand what I'm eating," he said. In addition, MealSnap can serve as a food diary, allowing users to keep a readable record of the meals they have eaten. Mr Smith said:"It's like a food journal, but easier.

The potential of MOOCs to reform education has been obvious in the US ever since the immediate popularity of the course Artificial Intelligence,taught by Stanford University professor Sebastian Thrun, who later co-founded Udacity, a platform with 1.6 million enrolled students in 200 countries. According to Nature magazine,by June 2013,74 percent of universities in the US offered some type of online course. Lu Fang, vice-president of Fudan University,explains the appeal of MOOCs as a simple case of supply and demand:"The demand for high quality educational resources from both enrolled students and professionals is feeding the rise of MOOCs,in which classes usually taught by top teachers are available to everyone,"said Lu. Too early to replace With easy access and free of charge, MOOCs are said to have the potential to change the present education system. But there are barriers,because hardly any universities offer degree certificates, as college administrators point out, it's difficult to confirm if students are foaming anything in MOOCs,reposed USA Today. The Wall Street Journal also reposed that,presently,a typical MOOC student is likely to have already graduated from college and is using the course to explore an interest or acquire professional skills. Even so, an increasing number of undergraduates are signing up. "What we are really establishing are educational pathways for people who want skills that are related to contemporary jobs,"Thrun told The Wall Street Journal. MOOCs have been considered likely to reform education since _ . | [

mmlu_train_35766 | JIUQUAN, China--China's Shenzhou-9 spacecraft blasted off at 6:37 pm Saturday, from a remote desert in western China, sending a crew of three, including the country's first female astronaut, into space. The successful launch, powered by a Long March 2F rocket, was shown live on state television Saturday from the Jiuquan Satellite Launch Center in the Gobi Desert in western China. The Chinese astronauts will complete the country's first manned space docking mission , an important step in Beijing's ambitious plan to build a permanent space station by 2020. Possible future missions could include sending a man to the moon. The crew is expected to spend more than 10 days in space and dock with the Tiangong-1 space lab module, which China launched in September 2011. Two of them will live and work inside the module to test its life-support systems, while the third will remain in the capsule to deal with any unexpected emergencies. China first launched a man into space in 2003, followed by a two-man mission in 2005 and a three-man trip in 2008 that featured the country's first spacewalk. In November 2011, the unmanned Shenzhou-8 successfully docked twice with Tiangong-1 by remote control. The manned docking would be considered a milestone for China's space program. China is hoping to join the United States and Russia as the only countries to send independently maintained space stations into orbit . It is already one of just three nations to have launched manned spacecraft on their own. The program is a source of enormous national pride for China, reflecting its rapid economic and technological progress and ambition to rank among the world's leading nations. What can be concluded according to the passage? | [

mmlu_train_49888 | Scientists believe that one of our most important means of knowing what is going on around us is the sense of sound. We are warned of danger by sounds. Sounds serve to please us in music. Sound has a waste product, too, in the form of noise. Noise has been called unwanted sound. Noise is growing and it may get much worse before it gets any better. In order to know how noise affects people and animals, scientists have been studying for several years. They are surprised by what they have learned. Peace and quiet are becoming harder to find. Noise pollution is a threat that should be looked at carefully. Sounds is measured in units called decibels . At a level of 140 decibels people feel pain in their ears. Trucks , buses , motorcycles, airplanes, boats, factories---all these things make noise. They trouble not only our ears, but minds and bodies as well. There is a saying that it is so noisy that you can't hear yourself think. Doctors who study noise believe that we must sometimes hear ourselves think. If we don't, we may have headaches, other aches and pains, or even worse mental problems. Noise adds more tension to a society that has already faced enough stress.
