Given the Question and Answer pair, detect whether the answer is acceptable or not. Denote acceptable answer as "yes", otherwise denote as "no". An acceptable answer is consistent with the context in question, detailed, long, and uses general knowledge of English. Answers that are not definite and suggest a variety of options are not acceptable answers.

Let me give you an example: Question: What's the difference between the following examples: Neither of my teachers are mathematicians. None of my teachers are mathematicians. 
Answer: Neither - not either - implies that there is a choice of only two. So 'neither of my teachers' is only correct if there are exactly two teachers, 'none of my teachers' can be any number.
The answer to this example can be: yes
Here is why: The answer is well in context with the question and gives a proper explanation to resolve it. Hence, the output "yes" is correct.

OK. solve this:
Question: What does "I'm game" mean and what is its correct usage? 
Answer: I'm game means that I am up for the challenge, but arguably more commonly, I agree... Q: Fancy going for a drink? A: Sure, I'm game... or Q: I was thinking of going shopping. Do you want to come? A: Yes, I'm game... As for correct usage, as with most idioms, use it as you will... there is no correct usage as such.
Answer:
yes
