Many people have this eating disorder. In the beginning of her story, Kessa is a normal 15-year-old. She is good at many things, especially dancing. She has danced for many years and loves it. One day her dance teacher tells her to continue eating right, but maybe lose a few pounds. Once Kessa hears this, she takes things too far. Instead of cutting down on snacks and junk food, she decides not to eat at all. She does not eat breakfast, lunch, or dinner. She begins losing weight and becomes slimmer and slimmer. But she loses weight to a point where she is unhealthy. As her poor eating habits continue, her parents start getting as much help as possible to cure their beautiful daughter.

Three men and three women will spend eight months living in a special place on the side of a volcano in Hawaii. They are part of an experiment that is designed to mimic life on Mars. Their mission began on October 15, 2014. NASA says it could send astronauts to Mars as early as the 2030s. The mission would take more than two years, so NASA needs to know how people would react to living in a small group, isolated from the rest of the world, for such a long time. Some people may become depressed or bored living under those conditions. By studying people living in similar conditions here on Eares NASA hopes to learn how to choose the most suitable people for a space mission, and how to help them get along. They will live in a two-story building. The ground floor is about 86 square meters, roughly the size of a small two-bedroom apartment. It includes shared areas like kitchen, dining room, bathroom, laboratory and an exercise room. The upstairs is less than half the size of the downstairs. It contains another bathroom and six small bedrooms. The building is located in an abandoned quarry about 2,400 meters up the side of Mauna Loa, the second biggest volcano in the world. It is constantly monitored for signs of volcanic activity. NASA chose the location because the appearance looks very similar to Mars. To make it more like being on Mars in the future, they are only able to communicate by email during the experiment. Meanwhile, there will be a 20-minute delay between the time when a message is sent and that when it is received. When they go outside, they will have to suit up in full spacesuits, just as if they were on Mars. The commander is Martha Lenio, a 34-year-old Canadian. During the mission, she will run experiments on growing food. The other members have backgrounds in physics and so on. None of them are astronauts. Question: What's the main purpose of the experiment? Options: A: To monitor signs of volcanic activity. B: To prepare for a space mission to Mars. C: To train the six people to become astronauts. D: To study the difference between men and women.

As graduation day came near, excitement increased. Being out of high school meant I finally grew up. Soon I would be on my own, making my own decisions, doing what I was interested in without someone looking over my shoulder . There was never any question in my mind that I would go to college.

As I reached out my hand, I knew that I was reaching not just for a piece of paper but for a new life. Exciting as the future of a new life seemed, it wasn't easy to say goodbye to the old _ -- the familiar faces, the' familiar routine.
