Had a go and got 12 out of 20 right - 60%. Thought I'd get around the 70% mark, but not to be.
A few surprising answers, like refs are obliged to call time off for players to tie up their boot laces. The off side law with the retreating player being put onside after the 10 kicks it is also bewildering. If the offside player was still on the wrong side of the offside line when the 10 kicks, what's to stop him from competing for the ball . I also have a real issue with the penalty for one player falling to ground in a ball chase. Probably meant to be an action against "hollywooding" but can't say I've ever seen it in practice.
