Question: Article: Campers Gene and Marie Marsden took pride in being good citizens when in the wild. While driving miles to the Green River Lakes area, they taught their children what they had learned in the bear safety handbook put out by the Bridger-Teton Forest Service. Mr. and Mrs. Marsden did their best to keep a tidy camp. As the handbook had said to hang all food at least ten feet off the ground and four feet out from the trees, they did that and locked their food in their trailer  at night. It was already dark when they went to bed, but they _ the campsite with flashlights, making sure nothing was left out. Following the bear book's advice, they slept a hundred yards from where they cooked their food, and kept the car near their tents, separated from the trailer, which they left up at the other camp. The Marsdens liked having their dog Spike on guard. But on the first night, Spike would not stop barking. When Marie Marsden pulled the tent open and shone her flashlight, she saw a young bear. They all piled into the car and drove quickly down the path, calling out of the window to Spike and abandoning the trailer. They drove to a pay phone and called a Fish and Game Department guard, who identified the bear by the white ring of the fur the Marsdens had seen around his neck. The authorities informed the Marsdens that the bear was a young male that they'd been keeping an eye on. The next morning, the Marsdens heard helicopters circling over the mountain and wondered if it might have something to do with the bear. After spending the night in the public campground, they drove back to their site. Wandering the area in search of clues, Marie came to a stop below a tall tree. She slapped her head and shouted, "Oh no!" "What is it?" Gene asked. Marie pointed at the ground where Spike's dog food bowl lay upside down. A week after their return home, the Marsdens read the headline in their local paper. "Bear Killed in Wind Rivers." According to the article, the Fish and Game Department had shot the young bear because, having been rewarded for invading  a human campsite, it would likely to do so again. The Marsdens knew they had been lucky in the encounter, yet much to their shame and sadness, they also knew that the bear had not. 
 Answer: They did what the bear safety handbook had said.

Answer: What do we know about the Marsdens?

Question: Article: Too much eating. Too many unhealthy foods. Too many ads for food. Too few activities. Different reasons are given for America's weight problem---a problem increasingly shared by other countries. Almost one-fifth of American children and teenagers are overweight. Schools have been asked to increase physical education, an important tool for public health. However, a recent study has shown an increase in the number of injuries in P.E. classes. Researchers say one possible reason for this is a decrease in the number of school nurses. Schools without a nurse on duty may be more likely to send an injured child to a hospital. Another possible reason for more injuries is a change in the traditional idea of physical education. This "New P.E." expands the kinds of sports that are taught. But activities that some schools offer now, like rock climbing and skateboarding, can also increase the risks, says Cheryl Richardson, who is with the National Association for Sport and Physical Education(NASPE). She also says not all states require P.E. teachers to be specially trained. Untrained teachers could be less likely to recognize unsafe conditions. Cheryl Richardson points to one of the study's findings -that injuries are often the result of contact with a person or a structure. This tells her that the teachers were not giving each student enough space to move around safely. Six activities produced seventy percent of all injuries: running, basketball, football, volleyball, rugby and gymnastics. The researchers say larger class sizes are another possible reason for the increase in injuries. Larger classes can mean less supervision . The National Association for Sport and Physical Education says twenty to thirty students in a P.E. class should be the limit.
