This is just wrong. Believing something is different from believing in something. I believe in Catholicism (the religion). I believe the Pope (what the person says). I believe in the Pope (all aspects not just what he says).
I believe you (something you just said) I believe in you (confidence in you as a person).
Eu construí a frase corretamente Ela acredita no que diz o rádio. E o sistema apontou que eu esqueci o verbo DIZ. .????
