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.

Question: Is penultimate commonly used in English, or are its variations (such as second to last) more common? I need to use it in conjunction with the expressions First Payment Date and Last Payment Date to name variables while programming. In my mother language (Portuguese) Penultimate Payment Date would be fine, but it feels strange in English. (I know feels strange is not very helpful, but I'd like to know how to convey the meaning in the most natural way.) 
Answer: Someone I know who is a native speaker of Spanish and a professor at a university in the United States has complained that when he used the word "penultimate" in class, the students don't know what he's talking about. The word is perfectly, unimpeachably, 100% correct. It is a bit of an upscale, literary word though. It certainly is a "term of art" in fields like linguistics, where it is used commonly to refer to syllables. I searched for the word in the Corpus of Contemporary American English, and divided the results by section: spoken, fiction, magazine, newspaper, and academic, and got these results: spoken: 10 fiction: 53 magazine: 55 newspaper: 36 academic: 93 total: 247 So, it is certainly used in all areas of English, with a moderate skew towards higher registers like academic writing. Depending on the intended audience, a writer contemplating using the word "penultimate" should consider that there is a relatively high likelihood that word will not be understood. Instead of "penultimate", the phrasing in common usage is either "next to last" or "second to last". Both of those should be universally understood. Interestingly, Google Ngrams shows that the word "penultimate" rose in usage (in published books) steadily from 1800 to about 1990, and since 1990 it has shown a steep dropoff, taking us back to usage levels from the late 1960s. The better-understood terms "second to last" and "next to last" are less common (again, though, in published booksGoogle Ngrams tells us nothing about spoken usage), with "next to last" having more historical usage but a slow tapering off of usage since 1960 and "second to last" increasing in usage from 1970 on, with both enjoying approximately the same usage today.

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: The "shot" in shotgun refers to the ammunition that the gun fires. Whereas a pistol or rifle fires bullets (single metal balls), a shotgun fires a shell packed with shot (hundreds of tiny metal balls).

Ex Output:
yes

Question: I've found this phrase here on a recent BBC report: "...the mare in the video died after suffering a cardiac arrest on a gallops in April 2016." The same article has: "A video on social media shows James mount the animal at a gallops while some present can be heard laughing." (emphasis mine) It's a bit of a sad story, but I want to know what "a gallops" is. Google Ngrams has some indication that it might be a phrase rather than just a typo, and also that it might be rising in popularity. TheFreeDictionary redirects me to gallop. I know what "a gallop" is. It's the plural noun ("a gallops") that I have never heard used before. It feels like some kind of horse racing meet. Any formal (or informal) definition that fits this word? Is it short for something? 
Answer: A gallops (or sometimes gallop) is a track or ground specially designed for training or exercising horses - see definition 1.3 here. They usually have a special surface, and might consist of a straight or circular track, often with a fence or rails. Note that this is a British English phrase, equivalent to the American English phrase "training track".
