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: Ele?­vators take you 100 m (328 ft) down to a sub?­ter?­ra?­nean river for a spooky boat ride past gigantic stalactites and stalagmites, formed by the calcite residue and deposits of thousands of years of persistently dripping water. Choices: 1. Stalagmites are said to bring good luck to anyone that passes one. 2. There are stalagmites formed from thousands of years of drippings. 3. All boat rides need to avoid areas with stalactites because of the danger surrounding them.
