"What are you drinking, milk?"
Translation:Что это ты пьёшь, молоко?
the problem given was that I needed to translate and use a word that I hadn't learned yet (ie. пьёшь). I was shown пьёт, but not пьёшь. maybe this needs to be put later on in the question order?
Happened to me, too. I've only encountered the пьёт lesson and then this one came out of left field. Had to guess but got it wrong. Duo should introduce the translation texts first (where there are hover hints) before the corresponding multiple choice questions. Otherwise, there's really no way but to guess the answer to sentences you see for the first time.
I put "Ты что пьёшь, молоко?" and it marked it as incorrect - is this an acceptable translation?
