Three boxes are labeled 'Apples', 'Oranges', and 'Apples and Oranges'. Every single label is guaranteed to be wrong. You are allowed to draw only one piece of fruit from one box to correct all the labels. Which box should you open?
The box labeled 'Apples and Oranges'
Since all labels are wrong, the 'Apples and Oranges' box must contain only apples or only oranges. Drawing one fruit from it instantly reveals its true contents, allowing you to deduce the rest.
