I think its A. but Im not completely sure :/
'They are falling apart into great blocks of stone, and the forest is safer going.' AND 'No man of my tribe had seen it, not even my father, the priest. It was magic and I prayed.'
In the first quote we see that the narrator is cautious because he talks of the god-roads falling apart. He says that "the forest is safer going". These elements of this quote show us that he is taking care. The second quote shows how rare it is for the river to be seen in his tribe. He says that it "was magic" and that he prayed. One can assume that he is praying because he is in the presence of magic and he is being cautious about what may happen next.
The answer for this would be poetry. Hope it helps!=)
