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: These two seem very similar. What are the major differences between the two? For example, in the following sentence, Substitute the lesser punishment for the greater one. Can one use "less" instead of "lesser" here? 
Answer: Less refers to quantity, lesser refers to quality. Your sentence could be rephrased as "substitute less punishment for more punishment." Here we are saying that the amount of punishment is smaller. But if you say "substitute the lesser punishment" you are saying the type of punishment is not as severe. Forty lashes is less punishment than 100 lashes. Being pelted with rotten tomatoes is a lesser punishment than being pelted with rocks.
Answer:
yes
