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.

[EX Q]: Question: There is a concept in computer science which deals with how to demonstrate negative binary numbers. Two methods for achieving this goal are ones' complement and two's complement. Since I got acquainted with these methods, this question never stops coming to my mind that why the apostrophe is placed differently in ones' vs two's? I also saw many articles using one's instead. Even Google suggests that I might be mistaken! So I want to resolve this issue once and for all. Is it a stylistic preference? What causes this difference? And please provide more examples of similar usage. 
Answer: Donald Knuth, that doyen of computer science, says in Art of Computer Programming, Vol 2.: Detail-oriented readers and copy-editors should notice the position of the apostrophe in terms like "two's complement" and "ones' complement": a two's complement number is complemented with respect to a single power of 2, whereas a ones' complement number is complemented with respect to a long sequence of 1s. Indeed, there is also a twos' complement notation, which has radix 3 and complementation with respect to (2...22) (base 3).

[EX Q]: 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.

[EX Q]: Question: Possible Duplicate: What day is next Tuesday? Imagine that it's Monday, the 1st. The weekend would be the 6th & 7th. How do you refer properly to the coming weekend, "This weekend" or "Next weekend"? I believe that using "next weekend" would refer to the 13th & 14th and "this weekend" would refer to this week's end. Technically the coming weekend (6th & 7th) would be the next weekend on the calendar. So which is correct? I'm hoping for a definitive answer with backing since this is an argument over opinion. 
Answer: The issue isn't as definitive as you might think. Ultimately, it comes down to what interpretation of "next" you consider to be correct. For example, the American Heritage Dictionary (4th ed) defines 'next' simply as Immediately following, as in time, order, or sequence Following this definition, "next weekend" will always mean the weekend with the start date in closes proximity in time. If the phrase is used during a weekend, of course, you'd be referring to the weekend following the one you are currently experiencing. However, the issue gets more complicated if you look to other definitions. The Oxford American Dictionary has a specific definition for 'next' when used in the context of time: (of a day of the week) nearest (or the nearest but one) after the present : not this Wednesday, next Wednesday Here, we're given the choice: it can either mean the weekend with the closest start date, or the following one (as specified by the parenthetical addition or the nearest but one). This definition has come about mostly because of usage development. Many words and phrases in the english dictionary have meanings contrary to their technical definitions, and yet are still used commonly and considered valid. Thus, while technically "next" implies immediate sequence, it is used in other ways (which dictionaries like the OAD have accommodated for validity), so it's really a matter of personal preference. For example, it is unlikely that I will even use the phrase "next weekend" during the week, because some people might be confused as to what I am referring to. Instead, I will say "this weekend," unless it is currently the weekend, in which case I will say "next weekend.".
