Q: Article: No one knows exactly when jazz was invented, or by whom. But it is said that it began in the early 1900s. Jazz was a new kind of music, for America and the world, and New Orleans was its birthplace. Who were the jazz pioneers? Most were blacks. This music was not written down, and at first only blacks played it. It was hard for white musicians to learn the new style. But soon they, too, were playing jazz. The popularity of this music spread. From New Orleans, it traveled up the Mississippi to Chicago, then to Kansas City and New York. By the 1920s, there were many jazz musicians, both black and white. Many of them were famous. One man was better than the rest. His name was Louis Armstrong. Louis Armstrong was a born musician. He was not only talented but also hard-working. He also had a good sense of humor and a big, good-natured smile. These personal qualities were valuable in his rise to fame. After he became famous, he traveled around the world. It seemed that everyone wanted to hear Louis play. But life was not always easy, especially at the beginning. Louis Armstrong was born in 1900 in New Orleans. His father never went to school and his mother could hardly read. When Louis was still a kid, his parents separated, and Louis lived with his mother. How hard their life was can readily be imagined. And yet Louis smiled through everything. He later wrote, "My whole life has been happiness. Life was there for me and I accepted it. Whatever happened has been beautiful to me. I love everybody."
Answer: His talent and hard work.

Q: Article: My student teaching experience was a wonderful adventure. I had to deal with various discipline and behavior challenges that occurred again and again. The greatest part of it was the relationship I developed with two students. One of the students was named Michael,whom I met when I was working for a kindergarten. Before I became a morning bus assistant, I'd heard that Michael was a challenging student who would always shout, stand up on the bus, make fun of other students, and distract bus driver. So I decided that each morning, when he got on the bus, I'd have Michael sit beside me. At first he didn't like this idea and pouted about it. But soon he settled down, knowing he had no choice. I began to talk to him about little things outside of school life, such as his weekend activities and things that he liked to do. I also listened closely to him When he talked and thoroughly responded to his ideas. As I gave Michael the attention that he needed,little by little, he began to behave better and better. His transformation was noticed by all, by the students and especially the bus driver. Another student I took a special interest in was a boy named Tony, a third grader. To some, Tony seemed to be a slow or passive learner. So I decided to see if I could find a way to motivate Tony to stay on the task. I would sit in the seat next to him and encourage him through every step of the work he was doing. This helped him to stay motivated and at least the work was getting down on time. Before long, he was paying more attention to his studies, and scoring high on all his tests. I knew that all Tony had needed was to be motivated on a one-on-one basis.
