"Wasn't Greece warm?"
Translation:Nach robh a' Ghrèig blàth?
The one with the accent. I wrote a bit of an explanation into this issue here: https://forum.duolingo.com/comment/36081499?comment_id=36081986
Long story short, we have a few things to fix from Tree 1 > Tree 2, so for the time being, two answers will show up as correct. A' Ghrèig is the correct answer here :)
