Keats structures this poem as a series of seemingly unanswerable questions put to the figures on the Grecian urn. Why does that strategy heighten the impact of the declaration in the poem's final lines?
A) It serves to remind the reader that the poet is always in control of what is and isn't known about the world of the poem.
B) It calls attention to the speaker's courage in finally confronting the owner of the urn aloud.
C) It emphasizes that the final lines call the speaker back to reality from the delusion that "unheard [melodies] are sweeter."
D) It illustrates how similar the silence of the urn is to the silence of the poem.
