We paused before a House that seemed

A Swelling of the Ground –

The Roof was scarcely visible –

The Cornice –

in the Ground –

What is one purpose of the simile in this excerpt?

AIt creates an uncertain tone by making the roof seem unstable.
BIt compares the grave to a house, making it seem inviting.
CIt supports the poem's carefree and casual tone.
DIt links two unlike things: the grave and the sun.
