Final answer:
The break between stanzas 3 and 4 helps convey shifts in voice and address in the poem.
Step-by-step explanation:
The break between stanzas 3 and 4 helps the poet convey shifts in voice and address in the poem. This break marks a transition in tone or perspective and often indicates a change in the mode or voice of the poet. It creates a pause or shift in the narrative, allowing the poet to explore different themes or ideas. For example, in Jean Valentine's poem 'The Messenger,' the break between stanzas 3 and 4 helps convey a shift in the speaker's contemplative tone.
