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: I was googling the reason for why it's called "shotgun" to ride beside the driver when it suddenly hit me - why on Earth is the firearm called "shotgun"?! Is there any other kind of a gun than one used for shooting?! Why is it called "shotgun" instead of just a "gun" or a more technical term (9-gauge, barrel gun etc.)?
Answer: There are other things that shoot 'shot'. Cannons fired grapeshot as an effective way to deal with infantry. This makes a 'shotgun' just a gun that shoots shot instead of a cannon that does so. This clever naming scheme is also visible for 'rifles' which are simply guns with barrels that have been rifled.

Output: no

Input: Consider Input: Question: A few days ago, a friend and I were discussing how every "rule" of English spelling or pronunciation has an exception, and every exception has an exception as well. Then I brought up the rule of a ph cluster equaling an f sound (as in phonetic, elephant, morph, etc.) as a pronunciation rule that didn't have any exceptions I could think of. Is this a true hard-and-fast rule or does it have some exceptions as well? I'm not counting abbreviations such as pH scale.
Answer: The exceptions come in two categories: Greek words that were originally pronounced with an "f" diphtheria, diphthong, ophthalmology, phthisis but have come to be pronounced with a "p" by no process I understand. Compound words uphold, saphead, peephole that are just a word ending in "p" run up against a word beginning with an "h". Neither of those really feel like exceptions: mispronunciations that have become accepted and two words being treated as one. Then there is aphelion. Arguably, that's a compound word and a mistake. By analogy with apogee and apastron, it should be apohelion: "apo" ("from") + "helion" ("sun"). Several people brought up "Stephen", which is often pronounced like "Steven". Eh, I think we should play with Scrabble rules: no proper names. Finally, there is an example that will really blow your minds: phthalate. The ph- is silent.

Output: yes

Input: Consider Input: Question: First of all, I am not a native English speaker and not very good in English too. I had a technical problem in my software project and thus took help of somebody. She helped me to find the right way to resolve my issue. Can I say her, "You are a path shower" to show my appreciation to her ? UPDATE: She always guides me when I am in trouble. Considering this, what more can I say her.
Answer: Most of these answer are so very flowery! I would simply go with "thanks for your guidance". It's appropriate for both formal and informal settings (unlike several of the other answers...), and straightforward. You could even flash it up: "thanks for your consistent, excellent guidance on this project" and keep it not too "puppy on the heels".
Output: no
