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: "Kinda sure of that, ain't you?" The smile had not cracked, nor had it reached those shuttered blue eyes. Choices: 1. He smiled and agreed with him.  2. With a dry grin, he said, "your pretty sure of that, aren't you"  3. Sarcastically he said," you really believe that, don't you?" He looked away with disbelief.
