"It is for the newspaper."
Translation:É para o jornal.
Unfortunately, Duolingo's hints are not always specific to the exercise, and even though it doesn't work here, Duolingo is correctly pointing out that "pelo" can be translated as "for the" in some situations. For example, "Ele espere pelo carteiro" (He waits for the postman).
Native speaker danmoller tries to explain the difference between "por" and "para" here: https://www.duolingo.com/comment/3185480.
