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: We have not seen anything that demonstrates that every coal-fired power plant would be able to achieve 90 percent source-specific controls for mercury by 2007, without considerable fuel switching, which would be very disruptive to our economy and undermine energy security. Choices: 1. We haven't seen anything that shows that coal-fired plants can hit the goals. 2. Everything we've seen shows that coal-fired plants can hit the goals. 3. We haven't seen anything that shows that coal-fired plants can hit the goals, so they need to be shut down.
