Question

Read the following passage carefully:

Silas worked in the herbarium of the botanical institute, a cavernous room lined with floor-to-ceiling wooden cabinets containing thousands of dried, pressed specimens. The air here was dry and smelled of old paper, mothballs, and the faint, dusty ghost of flora that had long since lost its color and scent. Each flower was flattened between sheets of heavy blotting paper, secured with precise strips of linen tape, and labeled with a Latin name in an elegant, faded hand. Silas spent his afternoons cataloging these specimens under the cold, white light of a single desk lamp, while outside the window, the summer afternoon hummed with the chaotic, unorganized growth of living ivy and the wild buzzing of bumblebees in the courtyard. The room was silent except for the dry rasp of paper as Silas turned the pages of his ledgers, a sound that seemed to mimic the dry rustle of his own thoughts. For forty years he had preserved the dead remains of nature, shielding them from the destructive touch of humidity and decay, yet in doing so, he had sealed himself in a climate-controlled vault where nothing ever grew, shifted, or died, but simply remained, fixed and bloodless, in perpetuity.

Which of the following best describes the narrative function of the contrast between the herbarium’s interior and the courtyard outside?
