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 pull one fruit from a single box of your choice. Which box should you pick from to determine the contents of 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 what is inside that box, and since the other two labels are also incorrect, you can easily deduce the rest.
