Which two words from "The Raven" by Edgar Allan Poe are examples of internal rhyme?
 Presently my soul grew stronger; hesitating then no longer, 
 "Sir," said I, "or Madam, truly your forgiveness I implore;
 But the fact is I was napping, and so gently you came rapping, 
 And so faintly you came tapping, tapping at my chamber door,
 That I scarce was sure I heard you"—here I opened wide the door:—
 Darkness there and nothing more.
 Deep into that darkness peering, long I stood there wondering, fearing,
 Doubting, dreaming dreams no mortals ever dared to dream before;
 But the silence was unbroken, and the stillness gave no token,
 And the only word there spoken was the whispered word, "Lenore?"
 This I whispered, and an echo murmured back the word, "Lenore:"
 Merely this and nothing more.
