Question

Read the following passage carefully:

The dining room table, a dark expanse of scarred mahogany, was dominated by a pair of silver-plated candlesticks that Haddon polished every Thursday. They had belonged to his uncle, a man of grand, unfulfilled ambitions who had left behind more debts than heirlooms. Under Haddon’s cloth, the silver plate was wearing thin, exposing patches of dull yellow brass beneath. In the dim afternoon light filtering through the lace curtains, these yellow spots looked like bruises on the metal, or perhaps like the first spots of decay on autumn leaves. Yet he rubbed them with a mechanical, desperate intensity, as if the polish itself could restore not just the luster, but the solid reality of the wealth they once represented. Outside, the whistle of the late-afternoon train blew, a shrill, lonely sound that cut through the quiet house and died away in the valley. Haddon stopped, his hand resting on the tarnished metal. The coldness of the brass seeped through the cloth into his palm, a reminder of the winter that had already settled into the corners of the room. The house, like the family name, was slowly turning into a shell of what it once was, and only the relentless routine of cleaning kept the looming emptiness at bay.

In the passage, the description of the yellow brass showing through the silver plate of the candlesticks serves primarily to represent which of the following?
