Given the task definition, example input & output, solve the new input case.
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: 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.
Output: no
It is not clear that M and M world is popular.

New input case for you: Sentence 1: I learnt afterwards that they nearly did away with me then and there there was never much chance of their 'letting me go' but the first man, who was the boss, preferred to keep me alive on the chance of my having hidden them, and being able to tell where if I recovered my memory. Sentence 2: The boss thought that I might be useful if my memory came back.
Output:
yes
