Three boxes contain fruit. One has apples, one has oranges, and one has both apples and oranges. Every single box is labeled incorrectly. You may reach into one box and pull out a single piece of fruit without looking. Which box should you pick to correctly label all three boxes?
The box labeled 'Apples and Oranges'
Since all labels are wrong, the box labeled 'Apples and Oranges' cannot contain both. It must contain either only apples or only oranges. Pulling one fruit reveals its true contents; the remaining boxes can then be deduced easily.
