Translation:I did not know how to answer your question.
So after an entire course, hours and hours of lessons and thousands of XP, it ends up that pergunta could have been "questao?" lolz
Every single time I get something wrong on duolingo... "Eu não sabia como responder a sua questão."
bad... I'm a native speaker and I still find maaaany things it should be right, but still considered wrong.. frustrating..
