Answer:
Internal rhyme
Step-by-step explanation:
In the poem, "Sympathy" by Paul Laurence Dunbar, the sound device utilized in the bolded lines is internal rhyme. Internal rhyme refers to the use of rhyming words within a single line of verse. In this case, the internal rhyme can be seen in the words "opes" and "chalice" in line 5. The use of internal rhyme can help to create a musical or rhythmic quality in the poem, as well as reinforce certain themes or ideas. In this case, the internal rhyme helps to emphasize the speaker's empathy with the caged bird, as well as the beauty and freedom that the bird is denied.
