What is the purpose of this passage from the myth?
to explain how the first humans came to exist on earth
to explain how the heavens, earth, and rivers were created
to explain how humans should act toward one another

the answer is both an appeal to ethos and logos (if that's what your question options were)

voracity is the noun corresponding to the adjective voracious, which means (1) eager to consume a great amount of food, or (2) marked by an insatiable appetite. veracity is far more common than the rare voracity, so the latter is sometimes used in place of the former.
