"Could you speak slowly?"
Translation:Você poderia falar devagar?
I got a rather strange explanation of my error: I misread the English sentence and typed "Você pode falar devagar". The explanation that I was given about my error was "You used the ele/ela form 'pode' instead of the eu form 'poderia'", which is horribly misleading, since the error is in the mood, not the person. I don't know how doable it is, but if the explanations could be tweaked a bit, that'd be great.
