We had a math contest today. I am good at math, so I ___1____it quickly. I was the first one to _____2___ the paper. I was sitting on my seat relaxing, while the teacher shouted, "Whose paper is this?" I made no response. Some time later, I suddenly realized that I didn't sign my name on the paper. I stood up ____3___ and went to the teacher. She helped me find the __4____ paper and sign my name. I would have failed the contest if she hadn't ____5___me in time.
