Answer:
Simile
Explanation:
A simile is a figure of speech that makes a comparison between two or more things while using the words “like” or “as.” It is often employed to give readers different insights about something and make writing more colorful. In this excerpt, Romeo uses a simile to express how remarkable and precious her beauty is when he compares the way she seems to hang upon the cheek of night to the way a rich jewel hangs from an ethiop's ear, and uses the word “like” to help make such comparison.
