[EX Q]: Article: Polar bears are born in dens on land and their mother stays with them for the whole winter without eating anything. The mother and the babies come out from the dens around March, _ from a long winter and must immediately go hunting to find food to stay alive. Now, the only hunting they know is to catch seals from floating ice in the open ocean. In March, polar bear mothers and babies have to swim from the land in Spitsbergen to the edge of the polar ice cap. Normally this is a short swim, since in March the polar ice cap is very close to the land, and the polar bears, and even the babies, are good swimmers. However, last year we saw that the polar ice cap had become smaller in size due to global warming. Swimming hundreds of miles, especially when they are hungry and have babies following them, is really hard, and many bears are dying because of starvation. The polar bear population in the Spitsbergen area was once threatened by hunters. In the 1970s, a ban on hunting was imposed and the polar bear population has been steadily increasing from just a few hundred to about 2,000 to 3,000. This was a great success story. However, now, because of global warming, the population is again in danger. If we do not stop making so much carbon dioxide, we will lose these beautiful animals forever. The polar bears are just one example of animals that have become endangered because of man's appetite for energy obtained by burning fossil fuels. All life on earth could be in danger unless we change our ways. What can we do? To reduce the amount of carbon dioxide in the air we must save and make energy without burning coal and oil. Instead, we can use the sun or the wind to generate electricity. We must also cut down on needless driving and turn off things that use electricity when we are not using them. In addition, we have to stop cutting down forests and start planting more trees.
Answer: To catch seals for food.
[EX A]: Why do the bears swim to the edge of the polar ice cap?

[EX Q]: Article: FRIDAY, Aug. 3 (Health Day News) -- Middle school students who are physically fit are likely to score higher on standardized tests measuring reading and math abilities, a new study has found. And, the average scores went up in connection with levels of fitness, the findings showed. "The more physically fit kids were, the higher their scores," said the study's lead author, Trent Petrie, director of the Center for Sport Psychology at the University of North Texas in Denton. "Parents should encourage their kids to be physically active. There are some real cognitive and academic benefits that come from physical fitness", Petrie said. Results of the study are scheduled to be presented Friday at the annual meeting of the American Psychological Association in Orlando, Fla. The study included more than 1,200 middle school students from five schools in a suburban area of Texas, with 561 boys and 650 girls. About 57 percent of the children were white, and nearly one-quarter were Mexican American. Nine percent were black and about 2 percent were of Asian descent. The school district provided the researchers with information on the children's race, age, grade level and whether they qualified for the free school lunch program, which was an indicator of the family's socioeconomic status. The schools also provided scores to the tests, which were given between one and four months after the researchers had assessed the children's levels of fitness. Fitness tests were administered during physical education classes to determine the youngsters' heart and lung health (cardiorespiratory fitness), as well as their body mass index (BMI), an indicator of how much body fat a person has. The children also filled out questionnaires that helped the researchers determine factors such as self-esteem and social support. After accounting for factors such as age, sex, family income and self-esteem, the researchers found that for both boys and girls, higher levels of heart and lung health predicted better scores on both the math and reading tests. For boys, perceived social support also seemed to increase their reading scores, the investigators found. In girls, while being physically fit predicted higher reading scores, so too did a higher BMI-- which indicates more body fat. "We were a little surprised by this finding," Petrie said. "It was not as strong an association as the one with physical fitness," he added. The authors suspect it may have something to do with girls this age entering adolescence, which may be related to a higher BMI and slightly higher brain development. He said he plans to make great effort to look for this relationship again in larger studies to see if it was a chance finding, or if the association holds up. "While we can't say 100 percent that physical fitness causes better academic performance, we can say that there is a strong and predictive relationship between physical fitness and academic performance," Petrie said. "It's hard to tease apart the exact reason for this association," said Becky Hashim, an attending clinical psychologist and assistant professor in the departments of psychiatry and pediatrics at the Children's Hospital of Montefiore, in New York City. "It may be that the children are getting more oxygen. When the heart and lungs are working at a higher capacity, it may allow the brain to work at peak performance. Children who are less fit may be sleepier during school," she noted. "I personally feel that there's probably a strong relationship between the confidence you get from being able to do something physical well and academic performance." Whatever the reason behind this association may be, "there's certainly no harm in pushing physical fitness," Hashim added. "Physical fitness may make you feel better, give you more confidence and improve your performance across the board," she said. Petrie agreed. "Physically fit kids are happier, have higher self-esteem and, tend to have better relationships, and now we're beginning to see that there also seem to be benefits cognitively and academically. Our study sends a strong warning to policymakers to reconsider the service program of physical education classes for kids," he said.
