Have another think about Q.10 - you can actually work out the answer, with a little knowledge of the competition format.
Quite happy to give the logic behind any of these questions/answers, if anyone is interested - after the game in question has taken place, of course.
In case anyone is wondering, I give the questions and their four possible answers a lot of thought. Some questions you will either know or you won't, but some can be worked out by the process of elimination. Such as Q.10.
