The correct answers are "peering" and "fearing"
Step-by-step explanation
The internal rhyme is the name used to refer to those words that rhyme and that are located in a single line of verse. According to this definition, it is possible to infer that the two words that constitute an internal rhyme in Edgar Allan Poe's poem "The Raven" are "peering" and "fearing" because both are located in the same sentence and sound similarly. Here is the verse of the poem:
"Deep into the darkness peering, long I stood there wondering, fearing,"
According to the above, the correct answers are "peering" and "fearing"
