Read the poem below and answer the question. That time of year thou mayst in me behold

When yellow leaves, or none, or few do hang

Upon those boughs which shake against the cold,

Bare ruined choirs, where late the sweet birds sang.

In me thou sees the twilight of such day

As after sunset fadeth in the west;

Which by and by black night doth take away,

Death's second self that seals up all in rest.

In me thou seest the glowing of such fire

That on the ashes of his youth doth lie,

As the deathbed whereon it must expire,

Consumed with that which it was nourished by.

This thou perceiv'st, which makes thy love more strong,

To love that well, which thou must leave ere long.

What type of sonnet is this?"
