Definition: In this task, you're given a statement and three sentences as choices. Your job is to determine the neutral choice based on your inference from the statement and your commonsense knowledge. The neutral choice is a sentence that neither agrees nor disagrees with the statement. Indicate your answer as '1', '2', or '3', corresponding to the choice number of the selected sentence. If sentence X agrees with sentence Y, one's correctness follows from the other one. If sentence X disagrees with sentence Y, they can not be correct at the same time.
Input: Statement: It's the right one, I suppose? asked Tommy doubtfully. Choices: 1. The doubt in Tommy's voice was as clear as the sky they stood under. 2. Tommy wasn't certain whether it was the right or wrong one. 3. Tommy was certain that this was the right one, not a doubt in his mind.
