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.

Example Input: Question: There is a person in my current daily life who never admits his wrongs. He is always quick to blame others first and always believes that he is not wrong. Even when he is proven wrong, he still believes he shouldn't be sorry and isn't wrong. Is there a single-word adjective to describe this behavior? If not, a better way to describe this person would also make do. While stubborn and irresponsible fit, I feel like they don't tell the whole story. By this, I mean if I were to say to others that he is very stubborn and irresponsible, it is not implicitly implied that he blames others and never acknowledges his own fault. Edit: I believe my question is different because the person will also never acknowledge their wrongdoing. On top of blaming others, even after it has been proven to be their fault, they will not admit wrong doing. So aside from blaming others, they refuse to acknowledge the possibility that they have committed a mistake. 
Answer: If he calls attention to the same thing when someone else does it, the word would be hypocrite. Otherwise, weasel seems to have the connotation (when I hear it used) of falsely accusing someone in order to avoid being found out, though I don't see that specified in the definition.
Example Output: no

Example Input: Question: There is a question titled "Does calling a road 'wavy' convey its shape clearly?" which looks like this is a duplicate, but in fact, it's not. In that question, there's talk of a road that slightly bends right and left, not up and down. So how do you describe a road that is up down and road? I am confused which word to use. There is one word to describe it. Can I say it is a zig-zag road? 
Answer: Undulated , sinusoidal In Spanish 🇪🇸 is. Ondulado , sinusoide. In Paraguayan 🇵🇾 Spanish is a little weird! Is something like: full of ups and downs :"lleno de arribadas y bajeadas".
Example Output: no

Example Input: Question: In my language, when I write an email to my professor, boss, etc, there is a greeting part in the first part of email right after "Dear prof. ..."(in my language of course), e.g. "How are you", "I hope everything is alright" and so on. But I don't have any idea how can I write a proper email with such a greeting in English? Or do I have to ignore it because the email is kinda formal? 
Answer: I almost always start formal e-mails with Dear Professor _, I hope this note finds you well. Some guidelines will suggest ending your salutation with a colon rather than a comma, but in many circumstances a comma is acceptable. If the person's title is "professor," you should spell it out (not "prof.") and begin it with a capital letter when it precedes the person's name (as it would in your example). "I hope this note (or letter) finds you well" politely establishes a friendly connection between you and the recipient of your letter and in most circumstances is a great way to start it. Especially if you're asking for something, it's good to indicate your concern for the person you're writing to. For the same reason, it's a good idea to end the letter with a phrase or sentence that will similarly show interest in their work or their well-being. "Best regards," is fine, but if you can tailor it in a way that's a bit more thoughtful, it's better. "I hope your book/project continues to go smoothly." (This can be followed by a "Best regards.") If this is a person you don't know, you may have to settle for a generic "Best regards" alone.
Example Output:
yes
