You have three boxes of fruit. One contains

just apples, one contains just oranges, and one

contains a mixture of both. Each box is labeled

 -- one says "apples," one says "oranges," and one

says "apples and oranges." However, it is known

that none of the boxes are labeled correctly.

How can you label the boxes correctly if you

are only allowed to take and look at just one

piece of fruit from just one of the boxes?
