"What language do you know except for English?"
Translation:Какой язык ты знаешь кроме английского?
This entire lesson needs to be updated by the course editors. I am being consistently marked incorrect for omitting pronouns where they are not needed. For example, "Какой язык знаешь кроме английского?" was marked incorrect. Very happy to have Russian on Duolingo though. Hope to see more integration of Cyrillic in the future. :)
I can't speak to the pronouns as I'm just learning but I'm curious about your "integration of Cyrillic" comment. You posted this a while ago so maybe you've figured it out by now, but in case someone hasn't:
You can toggle the use of Cyrillic/transliteration using the little Aa\Яя button at the top of the lesson screen.
