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.

Input: Consider Input: Question: Is there a single word to describe birds that can fly? Am I struggling to think of a word because the default notion of a bird is that it can fly? So we generally only need to differentiate the ones that can't fly. I've seen the term "winged" in a few google searches, but to my mind an ostrich is winged, but it is also flightless. I guess I'm looking for the word you'd put into this blank: Penguins are flightless because they cannot fly. Ostriches are flightless because they cannot fly. Pigeons are ____ because they can fly. 
Answer: In German we have it easy: 'flugfahig' and 'flugunfahig'. Deepl gave me this translation So it might be airworthy you are searching for, though it may only be used for contraptions and not for animals.

Output: no


Input: Consider 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.

Output: no


Input: Consider Input: Question: As per title of the question, I see this a lot. "We will release the product when issue 51 has been finalized." "We are waiting for it to be finalized." Is this just a case of people trying to sound professional with corporate jargon , or is there a real difference between 'finish' and 'finalize'? 
Answer: The definitions of finalise and finish are pretty similar, with finalise referring to the production of, or agreement on, the finished version. The single word finalise carries the connotation of just the last bit, whereas finish needs helper words to carry that connotation (e.g. finish off, finish up). Saying that something is finished can also carry the unwanted sense that it is done for, that is, that it is of no further use; finalise doesn't carry that unwanted sense. In commerce (including the fields of software engineering and management that you specifically referenced), completion isn't always enough. The customer wants confirmation of completion. Transacting parties want the signed agreement that follows the completion of negotiations, or the invoicing and payment that follow the completion of work. So it isn't enough that the work is finished (even in the positive sense); it needs to be finalised.


Output: yes
