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.

Example Input: Sentence 1: And while it would be a mistake to say that the stock could have opened at that highest price, it's safe to say that if Robertson Stephens had done a better job of gauging demand, millions of dollars that went into traders' pockets would have gone into Pixar's vaults instead. Sentence 2: Many people lost their jobs due to Robertson Stephens failure to properly calculate demand. 
Example Output: no

Example Input: Sentence 1: Lummox was his first brill, a gift from Ca'daan, and he didn't want to lose her. Sentence 2: Ca'daan gave him Lummox.
Example Output: yes

yes
