Please would anyone explain this to me? I'm trying to understand how they got to this model answer for a harmonization question. I'm looking at the part in the attached snapshot, where they have suggested Ic to Va. The melody is in grey and they have suggested the black notes. However, are there not consecutive octaves between the Fs in the bass and the Fs in the alto part? Or do consecutives only mean consecutives between the bass part and the melody?
