Mind you, I sometimes wonder if editors always get it right when they decide to move a quiz to a different sub-category. My "Curse of the Ninth Symphony" was moved to the "Beethoven" sub-category, presumably because the introduction starts with the words "Beethoven completed nine symphonies before his death."
However, it then goes on to explain "Since then, some composers have been superstitious about reaching this total, and a surprising number have in fact failed to make it to number ten. This quiz tests your knowledge of some of them." In fact, none of the questions are actually about Beethoven at all, and it is a source of occasional wonderment to me that I have never had a correction notice pointing this out!
But I must say, that is an isolated incident, and I think the editors do a great job, and no doubt have to put up with no end of difficult customers who fail to appreciate just how hard it is.
