Instructions: 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: A duplicate is not merely the submission of exactly the same case twice by computer or other error, but also any situation in which the same client returns to the program with the same legal problem in the same year. Choices: 1. There are different types of duplicates, some of which are more common than other. 2. There is only one sort of duplicate and that's when a computer error occurs. 3. If the same client returns with the same legal problem the same year, that's considered a duplicate.
