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.

[EX Q]: Question: Let's imagine a hypothetical business: Mistake Corp. Mistake Corp makes a lot of mistakes, and as it turns out, the reason they make these mistakes is typically the same. 90% of the time Mistake Corp makes a mistake, it's because of misinformation. I suppose misinformation is the opposite of a linchpin for Mistake Corp. I'd like to be able to use the word like so: "Misinformation is the [anti-linchpin] of Mistake Corp" What non-ambiguous word, other than "anti-linchpin", can I use to describe something that is a frequent cause for mistakes to those who aren't as English-savvy?

[EX Q]: Question: I want to ask whether I can use the word "Fuck" in a formal context. Apparently, the word dates back to the early 16th century, so it shouldn't be considered slang (although, it is misused as slang for other reasons), but regardless of its vulgarity, could I use it in a formal context with its original definition? I imagine that people will be surprised, but when realizing in what context I am using it in, then it will be more understandable and acceptable to use it. Firstly, I do not even know the definition of the word due to its vastness in meaning, I always thought it was an exclamation-like word meaning nothing (for it to mean sexual activities is a slang definition, is that not correct?), but used purely for emphasis. What does it first and foremost mean in its original/accurate and/or formal definition? I also know of another definition of the word "Fuck," which is "I will fuck you" as in "I will defeat you" (in context of fighting or combat), is that a formal definition as well? I mainly ask for this, because I need to use the word in this context, specifically and especially. Also, side question, is it possible not to always make it a vulgar word? Thanks in advance. 
Answer: It is very unwise to use "fuck" in any formal context whatsover (outside of technical discussion of language). The word either has strong and forceful sexual meaning, or it has the debased banality of over-frequent use by those groups of society who lack nuances and who express themselves repetitively and coarsely. In neither case does the usage fit with formal discourse. In short, although an excellent word to describe a very pleasant and necessary activity, it is rude.
[EX A]: no

[EX Q]: Question: I overheard my manager asking "What are you up to?" What does that idiom mean? Is it an informal/negative way of asking?? 
Answer: "What are you up to?" means "What have you been doing lately?". If you add an adverb to the end of the phrase, for instance, "What are you up to tonight?" or "What are you up to this summer?" it can be interpreted as "What are you planning to do tonight?" or "What are you planning to do this summer?".
[EX A]:
yes
