Needs an article before "doctor's" for example "the" or "a"
"A" is not correct because doctors' is plural.
Correct!!! I use "the Doctors" and they set it wrong.
You can change "doctors' " to "of the doctors" and you still need an article for the abstract noun.
It should be "what responsibilities do doctors have?" or "what responsibilty do doctors have?" Duolingo needs to fix this. What they have is incorrect.
What is the doctor's responsibility my god dualingo sucks
Yeah Dualingo is no good. Duolingo is really helpful for learning languages, however.
"What are the doctor's responsibilites?" is way more proper
I think that my ansewer is right, because the question is plural doctors, "cac Bac si," not the Doctor's respobsability only one Doctor.
