Which line in this excerpt from act I of Shakespeare's Romeo and Juliet contains alliteration?

ROMEO: Like a rich jewel in an Ethiope's ear;

So shows a snowy dove trooping with crows,

As yonder lady o'er her fellows shows.

The measure done, I'll watch her place of stand,

And, touching hers, make blessed my rude hand.

Did my heart love till now? forswear it, sight!

For I ne'er saw true beauty till this night.

Answer: So shows a snowy dove trooping with crows.

Explanation: alliteration is a literary device that consists in the repetition of the beginning sounds of consecutive words, or words that are close to each other. In the given excerpt from William Shakespeare's "Romeo and Juliet" the line that contains alliteration is "So shows a snowy dove trooping with crows" because, as we can see there is a repetition in the "s" sound at the beginning of the words "so," "shows," and "snowy."
