Question

Excerpt from "Birches"

by Robert Frost

He always kept his poise
To the top branches, climbing carefully
With the same pains you use to fill a cup
Up to the brim, and even above the brim.

Which poetic device does the poet employ in these lines from "Birches"?
A. simile
B. rhythm
C. metaphor
D. personification

Answer 1

C. metaphor

is indeed correct.

Answer 2

I think it is a metaphor because he is saying he has the same pains as filling up the cup, without using as or like.
