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: In addition, systems should incorporate incentives for people to do the right thing, adequate transparency mechanisms to provide reasonable assurance that people will do the right thing, and appropriate accountability mechanisms if people don't do the right thing. Choices: 1. Some managers believe that people know right from wrong and that the honor system should be enough. 2. The system shouldn't have built-in incentives that encourage people to do right. 3. Benefits that encourage people to do the right thing should be incorporated into proper systems.
