Article: It's not easy to find a person with the qualities it takes to be a hero. I didn't really understand the meaning of the word "hero" until my third year in the college. If you saw her, you wouldn't think she really looks the part, but she is stronger than Superman could ever be. Her name is Sandra Keierleber. I first met her at volleyball tryouts , but didn't notice anything special at first. As the week passed, however, she showed she had more heart than anyone. She stood out because she never gave up, no matter what. Sandra isn't the tallest or the fastest --- in fact, this was her first time playing volleyball and it showed--- but that didn't stop her. She was always the first to arrive and the last to leave. By the end of tryouts she had found a place in everyone's heart. When the name list for new members was put up, we all waited nervously as she checked. When she stood at the door and smiled happily, all we could do was cheer. After Sandra made the team, she worked even harder to improve her game. When she asked for help, we gladly taught her. She also became our fan, attending almost every school game and even joining us in the city games. We all like her, because she never thinks about doing things the easy way, or loses that smile. Because of her great efforts, she makes herself a true hero--- and my hero, too.

Article: As I was busy working on my work plan in my bedroom, I could hear my four children playing upstairs. Suddenly, I heard the children running down the stairs and shouting, "Freddie, Freddie." _ My three-year old son Freddie was lying on his side on the ground. I cried for my husband Simon to dial 999 and within minutes the air ambulance arrived. They quickly took him in the helicopter. During the flight, Freddie was looking at me and I remember thinking was a good sign, but then his eyes began to roll. As the doctors tried to stabilize him, I couldn't believe what was happening. When we arrived at the hospital in Portsmouth, there were some doctors and nurses waiting for us and they immediately set to work on Freddie. I was hopelessly wishing everything would be alright, but Freddie had broken his skull in two places and blood clots were forming in his brain. He needed surgery , and only a surgeon at another hospital in Bristol could do it. This meant another helicopter ride, but we couldn't go with Freddie because there was no enough space. Simon and I drove the long 130 miles from our home in north Devon in silence. Neither of us dared say what we were thinking, "What if we get there and he's dead?" "Is he going to be brain-damaged?" Freddie was just coming out of surgery when we arrived. The surgeon said it had gone well. When I finally saw him, I hardly recognize my child--he was covered in tubes and there were wires coming out of his head. On the third day, Simon went home to see our three girls and to pick up some clean clothes for us. While he was gone, the pressure in Freddie's brain suddenly increased. He was taken into theater again and this time I fell apart. Luckily, the surgery managed to stabilize Freddie. After almost a week, Freddie was finally woken up. When he opened his eyes, he looked at me. He didn't say anything, but I knew straight away that it was my old Freddie, and that he was going to be alright. Over the next two weeks, his recovery went well. After help with learning to swallow again and encouragement with speaking, he was soon playing with his Gruffalo cards and eating meals by himself. I still don't know how the accident happened, but we got some idea from our girls. Clearly Freddie and Minnie had been sitting on the window ledge, and Freddie must have opened it to look out and fallen 20 feet onto the ground below. The guilt I feel is awful-- for weeks I was full of " if onlys", and we put window locks everywhere. Six months later, although the accident seems a lifetime ago, it has changed me. I feel differently about life now. I've left my job to put my children first. I want to spend every minute with them.
Answer: Because no surgeons in the first hospital could do surgery on the author's son.
Why did the author's son have to be moved to another hospital in Bristol?

Article: Andy Steele lives just a few blocks from the campus of Black Hills State University in Spearfish, S.D., so commuting to class isn't the problem. But he doesn't like lectures much, isn't a morning person, and wants time during the day to restore motorcycles. So Steele, a full-time senior business major, has been taking as many classes as he can from the South Dakota State system's online offerings. He gets better grades and learns more, he says, and insists he isn't missing out on the college experience. "I still know a lot of people from my first two years living on campus, and I still meet a lot of people," he says. But now, he sets his own schedule. At least 2.3 million people took some kind of online courses, according to a recent survey by The Sloan Consortium, an online education group, and two-thirds of colleges offering "face-to-face" courses also offer online ones. But what were once two different types of classes are looking more and more alike and often falling into the same pool of students. At some schools, online courses originally intended for non-traditional students living far from campus have proved surprisingly popular with on-campus students. A recent study found 42 percent of the students enrolled in its distance education courses were located on campus at the university that was hosting the online courses. Numbers vary depending on the policies of particular colleges, but other schools also have students mixing and matching online and "face-to-face" credits. Motives range from lifestyle to adapting a job schedule to getting into high--demand courses. Washington State had about 325 on-campus undergraduates taking one or more distance courses last year. As many as 9,000 students took both distance and in-person classes at Arizona State last year. "Business is really about providing choices to their customers, and that's really what we want to do," said Sheila Aaker, extended services coordinator at Black Hills State. Many schools, such as Washington State and Arizona State, let departments and academic units decide who can take an online course. They say students with legitimate academic needs a conflict with another class, a course they need to graduate that isfull--oftenget permission, though they still must take some key classes in person.
Answer: To show more on-campus students are taking online courses.
