Question

Read the following passage carefully before choosing your answer:

Beatrice aligned the paper packets on the slatted bench of the potting shed, her thumb tracing the embossed lettering of seeds she would likely never see blossom. The October air was thin, smelling of damp peat and the sharp, vinegar tang of rotting crabapples. It took her three full minutes to fold a single flap of burlap over the dry tubers—a slow, deliberate choreography dictated by the stiffened joints of her hands. In this dim room, time did not flow; it accumulated like dust on the panes, thick and motionless.

Then, a sudden gust rattled the loose leaded glass, and the scent of ozone cut through the peat.

Instantly, the walls of the shed dissolved into the gray expanse of the 1974 deluge. She was twenty again, running along the canal path with Julian, the water rising in muddy, roiling swells that swallowed the willow trees in gulps. They had only hours to move the livestock. They ran, they hauled, they stacked heavy sandbags until their shoulders burned and their breaths came in ragged tears. The river was a ravenous beast, devouring land with terrifying speed, forcing decisions in seconds that would alter the valley for decades. The day was a blur of gray water, sweat, and screaming wind, compressed into a single, breathless heartbeat of survival. Julian had shouted something over the roar of the spillway—a warning, or perhaps a promise—but the current swept his voice away before she could grasp it.

A drop of condensation fell from the tin roof of the shed, striking the back of her hand with a cold shock.

Beatrice blinked. The deluge was gone, replaced once more by the silent, dusty rows of seed packets. The burlap lay half-folded. She looked down at her swollen knuckles, noting how the skin had withered, resembling the dry paper packets she held. She picked up a wooden marker, her pen scraping against the cedar with a slow, dry friction that seemed to stretch the silence of the afternoon into an eternity.

Which of the following best describes the primary function of the contrast between the slow pacing of the potting shed scenes and the rapid pacing of the flashback to the 1974 deluge?
