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: Unfortunately, at the time I was so sure of myself that I even self-imposed a deadline. Choices: 1. I didn't care when the project was done. 2. The project was tough and many warned me about it, but I believed in myself to get it done so I imposed a deadline on myself. 3. I imposed a deadline on myself because I was so sure in my abilities.
