The two types of figurative language used in the excerpt are:
-
metaphor - The phrase "papery brown mountain" compares the piles of leaves to a mountain, creating a vivid image without using "like" or "as."
-
hyperbole - The expression suggests that the amount of leaves was overwhelming, possibly exaggerating the situation for effect, as it implies that the task took "the remainder of our day," which emphasizes the enormity of the job.
So the correct answers are metaphor and hyperbole.
