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: All of the regulatory agencies that we examined explicitly permitted the public to submit electronic comments on some, but not all, of their recent proposed rules. Choices: 1. Most regulatory agencies were eager to hear public opinion on their proposed rules. 2. Every regulatory agency allowed some proposed rules to be publicly commented on through electronic means. 3. The public was never allowed to submit electronic comments about proposed rules.
