Question

Read the passage carefully:

Julian sat at the corner table of the Cafe De L'Aube, a spot he had claimed every afternoon for the past twelve years. Outside, the city of Oakhaven was transforming; glass towers rose like modern monoliths, and the old cobblestones were being paved over with smooth, dark asphalt. But inside Julian’s sphere, time was a circular, repeating track. He adjusted his silver pocket watch, aligning the minute hand precisely with the tolling of the municipal clock, and opened his leather-bound journal. With a fine-tipped pen, he recorded the arrival of the 3:15 bus, noting the number of passengers who disembarked. A young woman at the counter tried to make conversation, mentioning the new light-rail system opening next week, which would render the old bus routes obsolete. Julian merely nodded, his eyes fixed on the grid lines of his page. He did not look out the window at the construction cranes; he simply turned to a fresh leaf, drew a clean margin, and waited for the 3:45 arrival. The hum of the drills outside was nothing more than a faint, easily ignored vibration beneath his coffee cup.

In the passage, the description of Julian’s repetitive actions and indifference to the cafe conversation primarily serves to emphasize which of the following?
