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: The practice is common enough that a medical ethicist didn't raise eyebrows at the hospital where I completed my internship when he surveyed residents about how many had placed central lines into comatose or on-the-verge-of-death patients. Choices: 1. It's a common practice so many people dont think twice about it 2. Because the practice is common, everybody has had it 3. Nobody would try the surgery because nobody has heard of it
