Answer 1

With the speaker's conversations with the raven

Answer 2

One way in which Edgar Allan Poe creates a unity of effect of longing in "The Raven" is through the use of repetition. The repeated refrain of "nevermore" throughout the poem accentuates the protagonist's sense of loss and deepens the feeling of longing for his deceased love Lenore. This repetition creates a haunting and melancholic atmosphere that contributes to the overall effect of longing in the poem.
