I'm pulling questions together for a quiz we're doing at work on Thursday. I need good questions (and answers) that I can use.

I don't want them too difficult cos its no fun when people score zero, but too easy isn't good either.

Average age of participants is about 40. Assume they are not the world's most intelligent!

UK-based questions would be best.

THANKS IN ADVANCE!
