As noted in a previous discussion, I (almost) always look up the subject of the QOTD, due to the interesting little tidbits that I gain on the side. I did so again today, but happily my initial answers were correct (which is not always the case). Looking back, I don't think this was too difficult a question, but I am one of those whose initial reaction to a multiple-answer multiple choice question can't be repeated here. But I will admit that one generally has to understand a multiple-answer multiple choice question in order to be correct rather than simply deducing the correct choice as is often possible with single-answer multiple choice questions. Good question! :satisfied:
