Question

Read the passage carefully:

The porcelain shepherdess lay in three clean pieces on the Persian rug, its painted blue eyes staring up at the plaster ceiling. Edith did not stoop to gather them. Instead, she stood by the open steamer trunk, a half-folded silk shawl draped over her arm like a dead bird. It was the same shawl her mother had worn to the assembly room twenty years ago, on the night Edith first understood that some cages are built of whispers. In that crowded hall, heavy with the scent of damp wool and tallow, she had watched her mother smile at the rector while pressing a lace handkerchief so hard into her palm that the linen tore. Edith had wondered then, with a child’s sudden, cold clarity, how long a thread could be stretched before it snapped. Now, the carriage was already idling in the gravel drive below, its wheels grinding a restless rhythm into the afternoon quiet. She looked from the broken figurine to the open window. The rain had ceased, leaving only the steady, monotonous drip from the stone gutters—a sound that, for all its repetition, promised nothing but the slow wearing away of the foundation.

Which of the following best describes the narrative function of the shift from the present scene in the bedroom to the memory of the assembly room?
