In each group of four languages, three of them are in the same language family, and one is not; or they may all be in the same family but three of them are in the same branch and one is not. Pick the language that is unrelated to the others, or is less closely related.
To be clear: Don't look for a choice that doesn't fit the category. They all fit the category.
In an effort not to scare people away, I put the easier questions in the first quiz. That left these. Good luck!
All language classifications are according to Glottolog.
