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: but you know we're supposed to have moon colonies by now but uh yeah cold fusion would have been great Choices: 1. We've already colonized the moon, so cold fusion is clearly the next thing to be discovered.  2. Cold fusion would be great but we were supposed to colonizing the moon at this point.  3. Cold fusion is clearly impossible just like the idea we'd be colonizing the moon today.
