John is on an island and there are three crates of fruit that have washed up in front of him. One crate contains only apples. One crate contains only oranges. The other crate contains both apples and oranges.

If he can only take out and look at just one of the pieces of fruit from just one of the crates, how can he label all of the crates correctly?
