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: Arab trade with India had long since whetted the appetites of the Muslims; when Indian pirates plundered their ships off the coast of Sind in 711, it provoked the Governor of Chaldea (now Iraq) to send troops with 6,000 horses and 6,000 camels to conquer the Sind rajas and offer the alternative of converting to Islam or death. Choices: 1. The rajas in Sind faced a choice: convert or die. 2. After Indian pirates plundered their ships, the Governor of Chaldea sued for peace. 3. Had the Indian pirates not attacked their ships, none of this would have happened.
