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: Skeletons of such extinct creatures as the saber-toothed cat, imperial mammoth, and giant ground sloth have been reconstructed from the fossils. Choices: 1. The saber-toothed cat evolved into a large predator, because its prey was also large.  2. Fossils have been used to reconstruct skeletons of extinct creatures. 3. The saber-toothed cat can be found alive and well today.
