I agree with the other comments. The audio does not suggest singular nor plural, so either answer should be accepted.
I agree with everyone else. The singular should be accepted. You could be speaking to one doctor in the formal tense.
you have to accept singula ror plural :doctor or doctors
The singular "médecin" should be accepted, because "vous êtes" could be a singular formal address.
The listening version of this question could be heard as singular médecin?
Why isnt it: "You are a doctor." Or "You are all doctors". I think it should be one of these...
It isn't "You are a doctor" because medicins is plural. As for "You are all doctors" you are adding a word (all) that isn't represented in the French phrase.
Why is there no “My answer should be accepted.” option under Report? This should always be an option.
I tried "medics." :(
