Article: Seth DeBolt is a plant scientist at the University of Kentucky US. He and other scientists wanted to find a source of fuel that poor people in rural areas of developing countries could use to make electricity. The United Nations Development Program says a billion and a half people have no electricity. A billion others have an undependable supply. Professor DeBolt went on a study trip to rural Indonesia. He saw that there was very little waste in the use of agricultural products. Everything that farmers grew was used for something. Even the remains of fruit that people did not eat were fed to chickens. Little waste meant there was little that could be used for fuel. Growing a separate fuel crop would take land away from food crops. That was something Professor DeBolt did not want to do. DeBOLT said, "The people at most risk with respect to energy poverty, typically they're the same people who have food insecurity issues as it is. And then any change in availability would be most damaging to that group of people." But he found one item that was in plentiful supply and would not create competition between food and fuel. Coconut shells are generally thrown out. Yet Professor DeBolt says it has an "excellent" heating value. All someone needs is a way to release that energy. DeBolt says he and his team see possibilities for coconut power. "Coconuts are growing here and these are the areas where there is possibility for energy poverty to be eased at least in part by these small-scale production systems." The researchers say these systems could provide as much as thirteen percent of the energy needs of a country like Indonesia. Other tropical countries with large crops of coconuts and similar fruit could benefit, as well. But DeBolt says this is not a perfect solution. There are technical questions, like how to safely deal with the dangerous waste produced in the process. And there needs to be money to get these projects started. Question: DeBolt thought it was not a good idea to grow fuel crops because _ . Yes or no, is the answer "it would make food problems worse"?

Article: That Upper class people generally have more educational opportunities, greater financial security, and better jobs than people from lower social classes, but that doesn't mean they're more skilled at everything. A new study finds, surprisingly, that lower class people are better at reading the emotions of others. The researchers were inspired by observing that, for lower class people, success depends more on how much they can rely on other individuals. For example, if you can't afford to buy support services, you have to rely on your neighbors or relatives to watch the kids while you're busy. One experiment researched on volunteers who worked at a university: some had graduated from college and others had not. Researchers used the educational level as an indicator for social classes. The volunteers did a test of emotion perception , in which they were instructed to look at pictures of faces and indicate which emotions each face was displaying. People with more education performed worse on the task than people with less education. In another study, university students who were of higher social status had a more difficult time accurately reading the emotions of a stranger. These results suggest that people of upper-class status aren't very good at recognizing the emotions other people are feeling. This is because they remember their upper status and they think they can solve their problems without relying on others. In the third experiment, people were made to feel that they were at a lower social class than they actually were, and they got better at reading emotions. "The differences between upper-class people and lower-class people are not something ingrained ," Kraus says. "It's the cultural environment leading to them." This work helps show that the traditional image of the classes is wrong. "It's not true that a lower-class person, no matter what kind of person, is going to be less intelligent than an upper-class person. It's all about the social environment the person lives in, and the specific... Question: What does the passage mainly talk about? Yes or no, is the answer "Upper-class people have trouble recognizing others' emotion."?

Article: Next time you hear a funny joke you'd better not laugh too hard. According to a paper published by the British Medical Journal, laughter isn't always the best medicine. Sometimes it can even be harmful. Professor Robin Ferner from the University of Birmingham, one of the authors of the study, found that bad things could happen to people who laughed too much. He says: "We found people with heartbeat problems which had stopped their heart, we found people who had fainted, and we found people who'd dislocated their jaws or burst their lungs." It seems that laughing can be no laughing matter. But it's not all _ . Professor Ferner says there are benefits to laughing when you want to lose weight, for example. Yes, that's right: laugh and be slimmer! Professor Ferner explains that: "You use energy when you laugh, you move your diaphragm , you expand your lungs, and both those things can be helpful." According to the research, laughing for a quarter of an hour can burn up to 40 calories, and if you laughed all day you'd use up about 2,000 calories, which is what most people consume in a day. But don't do that or you might end up with a painful jaw. Ouch! Or you might find people looking at you in a funny way. But I don't want to finish this article leaving you feeling desperate. Laughter comes naturally for most of us. Babies begin to laugh at around 3-6 months. So give in to your sense of humour and keep smiling. Life is short anyway. Question: Laughing too much may cause the following harmful results EXCEPT _ . Yes or no, is the answer "diaphragm movement"?

Article: It's been just over a year since 9-year-old Zion Harvey received a double-hand transplant , and now, what he really wants to do is play football. "I feel happy about my new hands, and I don't feel different. I like that now I can throw a football further than when I didn't have hands," he said. The nation's youngest hand-transplant patient has been working hard to learn how to use his new hands. He lost his hands and his feet 7 years ago after suffering a serious infection. In August, the boy showed off his new abilities by throwing out the first ball at a baseball game. Dr. Scott Levin, team leader of Zion's operation, said Zion coped with the operation better than many adults. "I've never seen Zion cry," Levin said. "He's just an amazing boy. He has such courage and determination and gives us all inspiration." Zion said his courage came from the two most amazing people: his mom and his grandma. His mother, Pattie Ray, said, "It's been a long journey but now I feel I am living in my dream. It's his dream, and it's mine, too. I' m just living through him, and I'm just here to support him in any way and help him do whatever he wants to do." However, Zion told reporters his mom wouldn't let him try out for football. His mom said it's too dangerous. She also pointed out that he might be playing against little kids, not professionals, and she told him they would discuss it later. Zion tried to counter her argument. "My next goal: convince Mom to let me play football," he said. Question: What did Dr. Scott Levin think of Zion? Yes or no, is the answer "He was well worth praising."?
