"Who brings the book?" should be accepted
Is "Who will bring the book?" wrong? Because I remember something like "I will bring the dinner" being correct for "Én hozom a vacsorát". I don't see a difference.
I only hear "ki hoz a konyvet". Is the "a" in kozza silent?
The audio on this phrase is very fast and unclear. Considering this is an early stage of the course I think is is spoken much too quickly.
