Teacher: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.
Teacher: Now, understand the problem? Solve this instance: Statement: The failure to constructively involve staff in an organization's improvement efforts means running the risk that the changes will be more difficult and protracted than necessary. Choices: 1. Including staff in improvement efforts makes change far more difficult than necessary. 2. Staff should be constructively included in improvement efforts to make changes easier. 3. It is always better to include staff in improvement efforts since they enjoy the outcome and the process.
