What is the effect of the poetic form used in "the raven"?
the use of regular meter in the lines of the poem create suspense.
the repeated final sounds in the last three lines of each stanza provides a familiar cadence to the poem.
the consistent length of each stanza makes the events in the poem predictable.
the refrain, set off on a single line by itself at the end of each stanza, strengthens the emphasis of those words.
