Teacher: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.
Teacher: Now, understand the problem? Solve this instance: Statement: Creating a city boasting a major harbour, including a 500-metre- (1,640-foot-) long breakwater, with little more than soft sand as a base, was undoubtedly a colossal feat of engineering. Choices: 1. It took a lot of engineering to create a city with a harbor that size. 2. The harbor was hard to contain because of the soft sand base. 3. The harbor has an eight hundred meter breakwater.
