Quiz to make you go 'hmmm...'

This quiz is a nit-picker's nightmare and a pain for pedants! The answers here may be tehcnicalities, context specific, or just obscurely interesting, but all are meant to be thought-provoking and hopefully make you go 'Hmmm', rather than 'Hmph!'

This quiz may quickly become controversial, but stirring healthy discussion is its main objective.

Some answers may be officially disputed, but are still listed if they have some kind of potential claims, but if I have made any serious factual errors please inform me.

Remember, this quiz is not intended to annoy or deceive, but meant to be educational and, above all, fun!
