Final answer:
Dickerson makes two comparisons in the poem: one regarding the genre of the poems as elegies and the other about the rhythm of Dickinson's poems.
Step-by-step explanation:
In the given options, the two comparisons that Dickerson makes in the poem are:
- Both poems are elegies - poems written to commemorate/mourn a death, and both poets are aware of writing within this convention, although they treat it differently.
- Many of Dickinson's poems are rhythmically similar to popular nineteenth-century songs. These similarities help us understand Dickinson's poetry and the impact of the musical quality in her work.
