Read the following article and select the best answer. Article: A year after graduation, I was offered a position teaching a writing class. Teaching was a profession I had never seriously considered, though several of my stories had been published. I accepted the job without hesitation, as it would allow me to wear a tie and go by the name of Mr. Davis. My father went by the same name, and I liked to imagine people getting the two of us confused. "Wait a minute," someone might say, "are you talking about Mr. Davis the retired man, or Mr. Davis the respectable scholar?" The position was offered at the last minute, and I was given two weeks to prepare, a period I spent searching for briefcase and standing before my full-length mirror, repeating the words, "Hello, class. I'm Mr. Davis." Sometimes I would give myself an aggressive voice. Sometimes I would sound experienced. But when the day eventually came, my nerves kicked in and the true Mr. Davis was there. I sounded not like a thoughtful professor, but rather a 12-year-old boy. I arrived in the classroom with paper cards designed in the shape of maple leaves. I had cut them myself out of orange construction paper. I saw nine students along a long table. I handed out the cards, and the students wrote down their names and fastened them to their breast pockets as I required. "All right then," I said. "Okay, here we go." Then I opened my briefcase and realized that I had never thought beyond this moment. I had been thinking that the students would be the first to talk, offering their thoughts and opinions on the events of the day. I had imagined that I would sit at the edge of the desk, overlooking a forests of hands. Every student would yell. "Calm down, you'll all get your turn. One at a time, one at a time!" A terrible silence ruled the room, and seeing no other opinions, I inspected the students to pull out their notebooks and write a brief essay related to the theme of deep disappointment.
