Read the following passage carefully before choosing your answer.

The glass plate was cold, even through the thin cotton gloves Marcus wore. Under the magnifying lens, the stars of the Cygnus constellation were reduced to tiny, silver-gray specks, suspended in a gelatin emulsion that had begun to lift at the edges. For three hours, Marcus had sat in the basement of the observatory, measuring the positions of these dead points of light against a grid etched by a hand long since gone to dust. The silence of the room was absolute, punctuated only by the dry, rhythmic click of the micrometer screw. Each turn shifted the plate a fraction of a millimeter; each shift represented light that had traveled for centuries before striking the telescope’s mirror on a damp November night in 1912. Time, in this room, was not a river but a shelf of dry specimens, cataloged and static.

But then his eye caught a small, irregular smudge near the margin of the plate—not a star, but a flaw in the emulsion.

Suddenly, the dry basement air was gone, replaced by the heavy, ozone-scented humidity of a July evening thirty years earlier. The sky was the color of a bruised plum. Marcus was nine years old, running through the tall orchard grass, his breath hot in his throat. *Hurry, Marcus, hurry!* his sister’s voice echoed, sharp with a fear he had not understood then. The storm was coming, the clouds rolling in like dark, heavy blankets, erasing the horizon. He remembered the wild, erratic flashing of the fireflies, blinking in frantic desperation against the gathering gloom, and then the first heavy drop of rain, cold and sudden on his collar. They were looking for the lost lamb, their feet slipping in the mud, the wind whipping the branches of the apple trees into clawing hands. The world had seemed to spin faster, the minutes compressing into a chaotic blur of noise and shadow.

Marcus blinked. The basement of the observatory returned, silent and dry. The micrometer screw was still warm from his fingers. He looked back down at the smudge on the glass plate—a tiny bubble where the gelatin had failed to adhere to the glass, frozen in the middle of a star field. He realized now that the smudge was at the exact coordinate where he had expected to find a binary star. The flaw did not merely obscure the star; it occupied its space, rewriting the map of the sky with a small, permanent error.

Which of the following best describes how the shift in narrative pacing in the third paragraph ('Suddenly... shadow') functions in relation to the passage's thematic exploration of memory?
