Step-by-step explanation:
The statement that best describes the impact of Edgar Allan Poe's use of both internal rhyme and end rhyme in "The Raven" is that the rhyme gives the poem an even rhythm and maintains the tension. Poe's meticulous crafting of both internal and end rhymes contributes to a rhythmic cadence that sustains the eerie atmosphere of the poem.
