Read the following article and select the best answer. Article: In the mid-1950s, I was a somewhat bored early-adolescent male student who believed that _ . One day, this approach threw me into embarrassment In Mrs. Totten's eighth-grade math class at Central Avenue School in Anderson, Indiana, we were learning to add and subtract decimals . Our teacher typically assigned daily homework, which would be recited in class the following day. On most days, our grades were based on our oral answer to homework questions. Mrs. Totten usually walked up and down the rows of desks requesting answers from student after student in the order the questions had appeared on our homework sheets. She would start either at the front or the back of the classroom and work toward the other end. Since I was seated near the middle of about 35 students, it was easy to figure out which questions I might have to answer. This particular time, I had completed my usual two or three problems according to my calculations. What I failed to expect was that several students were absent, which threw off my estimate. As Mrs. Totten made her way from the beginning of the class,I desperately tried to determine which math problem I would get. I tried to work it out before she got to me, but I had brain freeze and couldn't function. When Mrs. Totten reached my desk,she asked what answer I'd got for problem No. 14. "I...I didn't get anything," I answered,and my face felt warm. "Correct," she said. It turned out that the correct answer was zero. What did I learn that day? First, always do all your homework. Second, in real life it isn't always what you say but how you say it that matters. Third,I would never make it as a mathematician. If I could choose one school day that taught me the most, it would be that one. Question: The author failed to get the questions he had expected because _ . - the class didn't begin as usual - several students didn't come to school - he didn't try hard to make his estimate - Mrs. Totten didn't start from the back of the class
several students didn't come to school
