This question refers to the poem "Mending Wall" by Robert Frost.
Answer:
The repetition most clearly reflects the speaker's:
C. unfulfilled impulse to share his personal reflections with the neighbor.
Explanation:
The speaker of the poem "Mending Wall" is quite frustrated. He and his neighbor are rebuilding a wall, but he does not see any reason for the wall to exist. He wishes he could explain that to his neighbor, try to make him see the wall has no purpose or, at least, that its building should take some more consideration. However, his neighbor believes "Good fences make good neighbors," something he learned a long time ago and is not willing to give up on. So, the speaker remains frustrated. They mend the wall, but the speaker's thoughts are repetitive, his impulse to share his opinions ever present.
