Question

Read the following passage carefully before choosing your answer.

For forty years, Principal Bartholomew Croft ruled the corridors of St. Jude's Academy with the icy certainty of an absolute monarch. He was a man who measured the worth of a student by the crispness of their collar and the alignment of their margins. To him, the rules were not merely guidelines but the very scaffolding of moral order. When young Leo Hayes was caught drawing caricature sketches of the faculty on the back of his Latin exams, Croft did not hesitate; he administered the sentence of a three-day suspension, delivering it with a voice as flat and unyielding as slate. Yet, when the boy’s mother wept in his office, speaking of their poverty and Leo's desperate need for a scholarship, Croft merely stared out the rain-streaked window, offering no comforting words, only a stern reminder of the school's charter.

But that evening, after the school had emptied and the shadows stretched long across the polished oak of his desk, Croft opened the drawer where he kept the confiscated items. He did not incinerate the boy’s drawings as protocol dictated. Instead, he held them up to the dim green light of his desk lamp, his calloused fingers tracing the fluid, expressive lines of the sketches. With a slow, deliberate care that contradicted his daily rigidity, he slipped the drawings into an envelope addressed to a prestigious youth art foundation in the city, enclosing a letter of recommendation written in his own hand and signed with his official seal. He stamped it, walked out into the cold drizzle to mail it himself, and returned the next morning to enforce the dress code with his usual, merciless gaze.

Which of the following best describes the literary function of the contrast between Principal Croft's public enforcement of discipline and his private actions regarding Leo’s drawings?
