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.

What kinds of images does the word "twinkling" suggest?

dirt, earth, poverty, race
leaves, trees, green, spring
stars, dreams, looking upward, Heaven
darkness, sadness, loneliness, isolation

Brooks' poem depicts the situation of a poor elderly couple. Everything that surrounds them reveal their penury: the plain chipware, the creaking wood, the tin flatware. They have lived their lives in such poverty, and they have grown used to it, just like they have grown used to eating beans, a cheap food. Still, at the end of the poem, Brooks lets us know that, even in that environment - a back room full of beads and receipts and dolls and cloths -, they still remember their dreams. The word "twinkling" is the indication of that. It conveys the feeling of something bright, sparkling, which is usually associated to happiness. The "twinge" would be the painful memories; the couple has had both, good and bad times, hopes and tragedies. And, even in deprivation, those memories make their lives full.
