Definition: In this task, you're given a statement, and three sentences as choices. Your job is to determine which sentence clearly disagrees with the statement. Indicate your answer as '1', '2', or '3' corresponding to the choice number of the selected sentence.
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.
