Einstein's Challenge

This is fun. Enjoy.

Einstein's Challenge:

"Einstein's Challenge" is a fairly difficult logic puzzle. This puzzle is typically prefaced with a note explaining that it was written by Einstein in the last century (i.e., the 19th century) and that he claimed only 2% of the world's population could solve it. This story is likely apocryphal, and certainly more than 2% of all people could solve it, given enough time. Hopefully this won't detract from your enjoyment of it:

FACTS OF THE PUZZLE

There are five houses in five different colours.
In each house lives a person of a different nationality.

the same drink.
