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 case studies, the data coming in are analyzed as they become available, and the emerging results are used to shape the next set of observations. Choices: 1. The results of the data are used to shape the next observations.   2. The results of the data are promptly discarded.   3. Examining the data is an important step in determining all future observations.
