Pas should not be required in this sentence per the "ne littéraire" rule for pouvoir I wrote "je suis désolé mais je ne peux accepter" which was marked wrong.
I doubt if Duo would like "toutafé" either!
I think you're right that it should be accepted, but I also think that it's a bit beyond the level which Duo is trying to teach.
Why 'desole' is not accepted? I am not a female
I do believe it's Duolingo's fault that I didn't put "mais". It was an honest mistake and I should be paid damages for it.
Je suis désolée, mais je n'arrive pas à accepter.
In the "Career" section "je n'arrive pas à ..." was used for I'm unable to / I can't.
How do we know whether it is a male or female speaking? "I am sorry but I can't accept."
How do I distinq
Guish when to use the male or the female form?
