The two correct answers for the type of figurative language used in the excerpt are:
A. metaphor - The phrase "papery brown mountain" is a metaphor as it compares a large pile of leaves to a mountain without using "like" or "as."
B. hyperbole - The exaggeration of describing the leaves as a "mountain" suggests it is far larger than expected, which is characteristic of hyperbole.
So the correct answers are A and B.
