Match each excerpt to the correct stanza structure.

I am pretty sure that the excerpt from "Annabel Lee" by Edgar Allan Poe best matches with couplet

And with the exceprt from "In Memoriam" by Alfred Lord Tennyson best matches - quatrain

As for exceprt from "Nothing Gold Can Stay" by Robert Frost, its pair is definitely - octave

And what about the excerpt from "Hero and Leander" by Christopher Marlowe, the answer is sestet
