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: 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: I think you can just use flying to describe them; flying birds sounds perfectly normal and isn't a tautology, nor does it only apply to birds in the air, cf. the title of the Wikipedia article 'Flying and gliding animals'. It's obviously an awkward choice for your example sentence, where another option, volant, could be used instead: 2: flying or capable of flying (source: Merriam-Webster).
Example Output: yes

Example Input: Question: What is the difference between "Did you find?" and "Have you found?" When should I use the first sentence, and when the second one? 
Answer: Did you find is the simple past and indicates that you are no longer looking for it. Have you found is the present perfect and indicates a link with the present, specifically, that you could still be looking for it.
Example Output: yes

Example Input: Question: Most grammar checkers are capable of detecting the the misuse of "your" and "you're"; providing the necessary correction. I'm curious though, is there any sentence that can be constructed where replacing "your" with "you're" keeps the sentence grammatically correct, but changes the meaning? If this is not possible, what grammar rules are in place that prevents these edge cases from occurring? 
Answer: a. I love you and your bananas. b. I love you and you're bananas. This particular case depends on the your/you're coming after an independent clause followed by "and," since its feasibility depends on functioning either as a second direct object or as another independent clause. It also depends on the noun serving either as a thing that someone might be in possession of (the bananas we eat) or as an adjective or noun complement describing a person (bananas=crazy). Easiest if that noun is plural or uncountable. The same sentence could be constructed with nuts, garbage, and other nouns which I'll let you brainstorm because my stormer hurts. You can also (and thanks to @Barmar for drawing attention to this) use verbs, in which case they act as a gerund with the possessive pronoun and a present participle with the "you're." As in: a. I love you and your cooking. b. I love you and you're cooking. Or: a. I despise you and your smoking. b. I despise you and you're smoking.
Example Output:
yes
