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 is difficult to believe that these bizarre shapes, staircases going nowhere, and windows in walls without rooms were built in 1724 by a serious student, rather than in the last century by some deranged architect. Choices: 1. The student designed the building so bizarrely as an art statement.  2. It's obvious that a deranged architect designed this building with non-functional staircases.  3. It's unique because there are bizarre shapes, staircases that lead nowhere, and walls without rooms.
