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: Participants also noted that the PCAOB should take advantage of the fact that under the current environment no one has more motivation for getting bad auditors off the street than the accounting firms themselves. Choices: 1. The PCAOB should not be concerned with bad auditors at accounting firms. 2. Accounting firms are motivated to remove bad auditors. 3. Bad auditors are identified by cameras in the office lunch room.
