Question

Read the following passage carefully before choosing your answer:

Major Marcus Pendelton commanded the garrison at Fort Redoubt with a rigidity that bordered on the mathematical. To the men under his charge, he was a figure carved from cold granite, a soldier who measured the worth of a life by the straightness of a seam and the synchronous rhythm of marching boots. During inspection, his white-gloved hand could detect a speck of rust on a rifle bolt from paces away, and his reprimands were swift, delivered in a voice that brooked no argument. "An unpolished button is a crack in the empire's wall," he would frequently declare to the terrified recruits. Yet, inside the locked quarters of his cabin, Pendelton lived in a state of quiet rebellion against his own doctrine. His cedar chest held no crisp uniforms, but rather a collection of worn, threadbare civilian coats, their elbows frayed and their lining exposed. Each evening, under the dim light of a single tallow candle, Pendelton would painstakingly sew patches onto these garments using mismatched, colorful threads that he had scavenged from local tailors. He did not repair them to wear, nor did he attempt to make the patches blend in; instead, he seemed to relish the chaotic, uneven stitches. When his orderly once accidentally discovered the chest and stammered an apology for the untidiness, Pendelton merely closed the lid with a slow, deliberate tenderness. "In the field we must look like the state," Pendelton said softly, his usual bark replaced by a quiet fatigue. "But in here, a man must remember that he is held together by rags."

In the passage, Major Pendelton’s private practice of patching old civilian coats with mismatched threads is best understood as a narrative device that does which of the following?
