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: As we have previously reported, the extent to which individual accounts would affect national saving depends on how they are financed, how the program is structured, and how people adjust their own saving behavior in response to individual accounts. Choices: 1. The way that individual accounts are financed would affect national savings. 2. National savings would certainly be unaffected by individual accounts. 3. Most people would increase personal savings if individual accounts were implemented.
