Einstein`s Test

This is the famous Einstein`s test. A paper and a pencil would be helpful, also trial an error works to some extent.

There are 5 houses that are each a different colour. There is a person of a different nationality in each house. The 5 owners drink a certain drink. They each smoke a certain brand of cigarettes and also have a certain pet. No owner has the same pet, smokes the same brand of cigarettes nor drinks the same drink.
