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.
One 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.
Solution is here: yes
Explanation: The answer is well in context with the question and gives a proper explanation to resolve it. Hence, the output "yes" is correct.

Now, solve this: Question: A simple question that has sparked some debate, and I couldn't find a concrete answer anywhere. There seems to be two camps: The word plethora indicates plural, so therefore it should be "There are a plethora"; and the other camp says that there is only one plethora (which contains multiple), so it should be "There is a plethora". I've seen many examples of both. Is there a consensus, or is it just one of those things that can go either way?
Answer: There IS A whole bunch of reasons why you need to pay attention to encapsulation and collectives. There is a {ton of bananas} in the truck. There is a {whole ton of bananas} in the truck. There is a {bag of cloves} that I bought. There is a {box of cigarettes}. This is a {list of people} I am inviting. There is a {collection of artwork of various genres} in the warehouse. It is three days' {work} to finish painting the house. We have to look at he complex noun phrase as a whole. This is the super noun encapsulation. If there is only one collection, then there is only one collection. Regardless if there are many members in that singular collection. There is {singular complex noun}. There are {plural complex noun}. The following is a plural noun phrase encapsulated by a singular noun phrase: There IS my {having to deal with two hundred people who ARE attending the party} that IS giving me a headache. If we address the singular collection, we have to look at that collection as the singularised entity. If we wish to address the items (of the singular collective) in plural, we have to get rid of the collective encapsulation: There is a whole lot of people feeling depressed about the Patriots' failure to reach the Super Bowl. There is a lot of people feeling depressed about the Patriots' failure to reach the Super Bowl. There are lots of people feeling depressed about the Patriots' failure to reach the Super Bowl. There are many people feeling depressed about the Patriots' failure to reach the Super Bowl. Contractor: How many boxes of framing nails did you buy? Peon: I bought only one box.
