I don't suppose it will help you understand what I was saying if I point out that the person who introduced the term "incorrect" into this discussion was you, not me, that as I understand the language "imprecise" does not mean "incorrect" (it is imprecise to say "my bungalow is about 100 metres from the sea", but it certainly is not incorrect), and that in my view there was absolutely no incorrect use of English in the question or in the answer, just imprecise use. The wording of the question was imprecise, in that in permitted more than one interpretation, and although it seemed pretty obvious which meaning the author intended (unless he was playing trick questions; and he wasn't, so that was his meaning) a different interpretation was perfectly reasonable.

Most of the time no-one bothers to be precise - the common feeling is something like "what's the point of complete precision" (except when writing about mathematical logic, or formally provable correctness of algorithms, or that sort of thing) - but in QOTD we unfortunately see a trick question now and again and as a result any imprecision (no matter how slight) risks being interpreted very carefully, unlike normal everyday speech or writing - just look at the number of comments saying something like "I got it wrong because I thought it was a trick question" or of really ludicrous things like the recent suggestion that the use of the word "drive" in one of Steve's RAID questions made it into trick a question.
