Teacher: In this task, you're given a pair of sentences, sentence 1 and sentence 2. Your job is to determine if the two sentences clearly agree/disagree with each other, or if this can't be determined. Indicate your answer as yes or no respectively.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Sentence 1: Next to the MGM Grand you will find M and M World. Sentence 2: The candy has many fans who love its attractions.
Solution: no
Reason: It is not clear that M and M world is popular.

Sentence 2: Water is provided by ceterns and by water supplies that are shipped to the island.
