Soru

Read the following passage carefully:

The small attic room was dominated by an oversized oak loom, its beams thick and dark with years of accumulated oil and dust. For decades, it had stood in the corner like a silent, resting beast, its frame holding the tension of a hundred half-finished tapestries. Today, Margaret sat before it, her fingers tracing the warp threads that had gone slack. The wool she held was a dull, indigo blue—the color of a winter dusk just before the frost sets in. It had been spun by her mother during the last year of the war, intended for a blanket that was never completed. As Margaret attempted to tighten the tension beam, the wood groaned, a deep, resonant sound that vibrated through the floorboards. A single thread, dry-rotted and brittle, snapped with a sharp ping, the two severed ends curling away from each other like dying vines. She did not attempt to knot them back together; instead, she let her hands fall into her lap, watching the dust motes drift through the narrow shaft of pale sunlight that pierced the single window.

In the passage, the snapping of the dry-rotted thread primarily symbolizes which of the following?
