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: But the analogy, they say, is the nuclear Non-Proliferation Treaty that took 20 years to obtain 178 members--and only after the United States used sanctions to force the hand of reluctant governments. Choices: 1. The U.S. did not interfere in other governments' decisions to accept the nuclear Non-Proliferation Treaty.  2. The current pact is taking longer than 20 years to enact. 3. According to them it is analogous to the nuclear Non-Proliferation Treaty.
