Given Sentence 1 and Sentence 2, indicate your answer as yes when the two sentences clearly agree or clearly disagree with each other. If the relationship cannot be determined, answer with 'no'.
One example: A boy in a blue jacket rides a skateboard down the street. <sep> A blue jacketed boy is standing in football field.
Solution is here: yes
Explanation: This answer is yes because the boy can either be riding or standing but not both. Since the statements disagree, the answer is yes.

Now, solve this: A man stands on a dock near several boats, while 2 other men are on one of the boats. <sep> A man is sitting on a dock.
Solution:
yes
