Melyik a te ágyad. This is the correct answer
With word tapping it forces me to do "Melyik az önök ágya" but shouldnt that be "Melyik az õ ágyuk" ?
The model answer is given as "Melyik az te ágyad?" I assume this is a typo and reported it.
The correct answer is "Melyik a te ágyad?" Remember the definite article "a" become "az" before a vowel.
Yes. That's what I wrote. It was marked wrong. For more information, please reread my original post. ;-)
