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: Of course, such a diagnostic system may prove to be more unwieldy in the end and to annoy insurance companies (who hold frightening sway over all health-care endeavors), and it is politically unlikely that such a dramatic shift will occur any time in the near future. Choices: 1. The new diagnostic system would involve a lot of trial and error. 2. Big changes will not occur in that diagnostic system involving insurance companies. 3. The new diagnostic system would bring no changes.
