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: As was pointed out in our March 28, 1997, report, while the rule was published in the Federal Register on March 6, 1997, and was received in our Office and Congress on March 14, 1997, the rule stated that it was effective on April 1, 1997. Choices: 1. The rule did not become effective until nearly a month after its publication. 2. Rules published in the Federal Register are not immediately effective. 3. The rule became effective before its publication in the Federal Register.
