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: There's no expert in the world who could, without knowing its source, say for certain that [the piece] is not [by] Mozart, Cope boasted to Britain's New Scientist .

Cope is very proud of the products of his algorithms. 2. Cope asserts that his algorithms would beat the world best composers. 3. Cope agrees that his algorithms may not produce the best works, but they will be better than other human composers.
