Soru

Arthur stood by the heavy mahogany writing table, his fingers tracing the cold silver of the letter opener. The library was wrapped in the stillness of a winter afternoon, the only sound the slow, deliberate tick of the grandfather clock in the corner—each second falling like a heavy drop of water into a deep pool. For months, the routine of his days had progressed with this same sluggish, predictable rhythm, a dull succession of mornings at the office and evenings in the quiet parlor. But as he looked down at the unopened envelope bearing the postmark of a city he had spent decades trying to forget, the room seemed to dissolve. Suddenly, he was standing on the sun-drenched pier at Calais, the air thick with the smell of salt and coal smoke. It was the summer of 1888, and the crowd was a shifting sea of bright parasols and shouting porters. He could feel the desperate pressure of Clara’s hand on his sleeve, her voice pleading above the whistle of the departing steamship. In that single, breathless minute, the course of his entire life had been decided by his silence. Then, a coal popped in the hearth, releasing a sharp hiss that shattered the memory. Arthur blinked, the salt air vanishing, replaced once more by the scent of old paper and leather. The grandfather clock ticked on, unchanged, but the letter in his hand now felt impossibly heavy.

Which of the following best describes the narrative function of the sudden shift from the slow, rhythmic description of the library to the rapid memory of the pier at Calais?
