One night, I wondered what it would be like if I only asked questions. I decided that no matter what anyone said to me the next day, I would reply only with 1.
I loved to read about scientists and their discoveries, and I knew that scientists always started their research with a question. I hoped that I could become a scientist. Maybe by asking questions, I could train my mind to be 2.
I survived the morning easily. “Is there any egg?” I answered when my mother asked what I wanted for breakfast. “Is this seat taken?” I asked when my friend Mike asked where he was going to 3 on the bus.
In the classroom, Mr. Black spoke slowly and clearly while I listened carefully. The problem had been part of my homework the night before. I wrote the answer on the board, “Could the answer be 361?”
Mr. Black smiled and nodded. I thought,“How did I 4 to get through that?” I almost laughed because asking questions really was starting to become a 5.
I thought I had made it safely through the whole day, 6 what I had come to consider my experiment blew up at the dinner table when my dad asked me about my day. “What do I always do?” I replied.
My parents looked at each other. My father 7 again. “Well, I hope you went to school,” he said.
“Uhhh … why would you think otherwise?” I asked. My parents exchanged another 8 and were becoming annoyed.
“Do you think questions are a good way to train your mind to be active?” I asked.
“It 9 the question,” said my father. “Some questions are asked for 10 information. Those are good mind-training questions. Sometimes, people use questions to get the other person to say something. Sometimes people ask questions to get someone to agree with them. Those questions don't really achieve anything.”
“I guess my experiment didn't work,” I said, and I told my father about my 11.
“I think it worked 12!” my father said. “You made a discovery, didn't you? What matters is that you have put your idea into practice.”
