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.

Sentence 2: Individuals can send a package Priority with delivery conformation and it is 50cents more expensive than Priority Mail.
