Which excerpt from the poem " girl powdering her neck" by Cathy song is an example of a simile

"She dips a corner of her sleeve / like a brush into water" is your answer.

Explanation:

it uses like in the sentence and his comparing.

Here, Cathy Song compares a girl's shoulder to the shape of a hill's incline using simile:

"and the curve of a shoulder

like the slope of a hill

set deep in snow in a country

of huge white solemn birds."

Here, the poet compares to dipping of a sleeve to that of a brush in water using simile:

"She dips a corner of her sleeve

like a brush into water

to wipe the mirror; "

Is that the answer you were looking for or no? Or I was I being too literal/broad in looking for simile in the poem?
