Welcome to the Lunchtime Bonus Question.
The rules are simple. Every day at 1030 BST we give you an answer. You then tell us what the question was.
Marks are deducted for predictability, and a selection of your most wrong questions are published each day until about 1500 BST when the actual question is revealed.
The winner of this week's Lunchtime Achievement Award, and thus the prize keyring, is Alan Cotter for his cringe-makingly wrong question on Monday. Accepting his award, he said: "Great! That's my wife's anniversary present sorted."
