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: Some information in a case study is likely to be judgmental, particularly when observer and participant-observer modes of data collection are used. Choices: 1. Data collectors can't possibly avoid elements of judgement from their case study when acting as a participant-observer. 2. Observer and participant-observer modes of data collection are likely to bring some element of judgement to a case study. 3. Case studies using observer and participant-observer modes of data collection are always totally non-judgemental.
