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: Does "egoistic" and "egotistic" mean the same thing? 
Answer: No. While similar, they have some important differences. Consider this note on usage from the Oxford Dictionaries: The words egoism and egotism are frequently confused, as though interchangeable, but there are distinctions worth noting. Both words derive from Latin ego ('I'), the first-person singular pronoun. Egotism, the more commonly used term , denotes an excessive sense of self-importance, too-frequent use of the word 'I,' and general arrogance and boastfulness. Egoism, a more subtle term , is perhaps best left to ethicists, for whom it denotes a view or theory of moral behavior in which self-interest is the root of moral conduct. An egoist, then , might devote considerable attention to introspection, but could be modest about it, whereas an egotist would have an exaggerated sense of the importance of his or her self-analysis, and would have to tell everyone.

Question: I've read this and this. I know that the underlying question has been answered, my problem is of a different nature: I'm currently writing my master's thesis in CS and my professor thinks that the apostrophe possessive is only applicable to people. He claims to have spoken to a linguist from Cambridge who confirmed his opinion. Neither my professor nor I am a native speaker and the thesis is being written in Germany. Now, I know that he won't care if I just send him a couple of links to the answers here. So my question is: How do I convince my professor? Are there any "more scientific™" sources that I can point to? Examples of phrases: If each plant's humidity is displayed publicly [...] [...] shows an overview of the node's structure. Due to an issue in the network stack's IPv6 subsystem [...] 
Answer: As few people are addressing the '"more scientific™" sources' bit of the question, it should be pointed out that there are a number of English style guides out there, practically all of which should cover the topic of forming possessives with apostrophe-s (as it's a frequent issue even with native speakers). You should be able to find copies of at least one of the major ones in any decent University library. (At least at any decent University with English classes.) The Elements of Style by Strunk and White is the "gold standard" for many Americans, although there are many who disagree with many of the details. The Chicago Manual of Style is a well-used standard for (American) University usage. - The online version is unapologetic and direct on this topic: "The possessive of most singular nouns is formed by adding an apostrophe and an s", although it does go into more details. Fowler's modern English usage by Henry Fowler is also a well-regarded standard, particularly for British users. The Cambridge Guide to English Usage by Pam Peters has the benefit of the "authority" of Cambridge. Oxford, of course, has their own: The New Oxford Style Manual, though the title has varied with edition. If physical copies aren't something you're interested in, a number of organizations (particularly journalism houses) have their house style guides online. For example, the Economist makes no mention of the conjectured rule in its advice. The Guardian gives additional examples, and also completely omits the purported rule. Others can likely be found by searching, and other major organizations (like the Associate Press and the New York Times) have theirs as printed books. Many dictionaries also have usage notes in them. (In particular, I'll point out the comment from @ps2goat mentioning Oxford Dictionaries's online page.) Ultimately, though, it's exceedingly difficult to prove a negative. Even confronted with evidence that a large number of style guides and usage manuals for English have nothing approaching the purported rule, your professor might not be convinced that he is mistaken. If that is the case, your best choice is probably to reword things to avoid the issue.

Question: I am writing a poem for school. The verse with the word I need to change is this: 7 hours is too long In much too short a day You really don't care if you get an answer wrong Because you don't care a _____ about radioactive decay The only thing I can think of is the word shit, but that word is too offensive. I have tried looking for inoffensive alternatives at Real Life English's Not so Offensive Alternatives to Bad Words in English, and wordhippo but these alternatives do not sound great, especially in a poem. I also searched for don't care a ___ on the free dictionary by Farlex's idioms website and "don't care a fig" came up, alongside some other suggestions I tried from the autofill suggestions. Most worked literally, but I am looking for a more clever and poetic word or words that could be used in a way that relates to my poem. I am not just looking for any old answer. I do not want you to simply search for "don't care a" on google. I want suggestions that fit creatively into my poem. 
Answer: One option for a word is whit1 : the smallest part or particle imaginable Don't care a whit2 is even an idiomatic phrase: didn't care at all. Sally thought Joe liked her, but he didn't care a whit about her. I don't care a whit what you do with my old clothes. 1 Webster's Third New International Dictionary s.v. whit2 2 The McGraw-Hill Dictionary of American Idioms and Phrasal Verbs s.v. didn't care a whit.
