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: Although this approach seems reasonable, there is a potential for substantial overstatement or understatement because the amount of estimated domestic postage-based terminal dues calculated under this procedure represents 4 percent of total IC payments to FPAs and 14 percent of total DC payments. Choices:  1. The reasonable-seeming approach may include some substantial over- or understatement. 2. The postage-based terminal dues are added to the IC, FPA, DC, and AO payments. 3. This approach has nothing with the potential for error in it.
