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: You'll need to walk down a long steep corridor to reach it. Choices: 1. A long and downward sloping route leads you to it.  2. It's very difficult to walk down the corridor because of how steep it is. 3. You don't have to move as it is right here.
