Which is an example of a couplet from Shakespeare’s “Sonnet 18”? Shall I compare thee to a summer's day? Thou art more lovely and more temperate: Sometime too hot the eye of heaven shines, And often is his gold complexion dimm'd, But thy eternal summer shall not fade, Nor lose possession of that fair thou ow'st, So long as men can breathe or eyes can see, So long lives this, and this gives life to thee.

So long as men can breathe or eyes can see, So long lives this, and this gives life to thee.

Explanation:

A couplet refers to successive lines in a poem, play, drama or otherwise that rhyme and have the same length. Couplets can be Open or Closed with the former referring to couplets which exist in multiple lines as opposed to the latter where they would be in separate sentences.

In Sonnet 18, the answer above is the couplet as the lines rhyme by the use of the words 'see' and 'thee'.
