Read Gwendolyn Brooks' poem, "The Bean Eaters" and answer the question. They eat beans mostly, this old yellow pair.
Dinner is a casual affair.
Plain chipware on a plain and creaking wood,
Tin flatware.

Two who are Mostly Good.
Two who have lived their day,
But keep on putting on their clothes
And putting things away.

And remembering...
Remembering, with twinklings and twinges,
As they lean over the beans in their rented back room that
is full of beads and receipts and dolls and cloths.
tobacco crumbs, vases and fringes.

The use of repetition in the second stanza supports the poem's themes in what way?
