The best response to how the structure of the passage contributes to the meaning of the text is:
By using sensory language to emphasize the deterioration of Farquhar’s mental state.
The passage employs sensory details, particularly auditory imagery, to illustrate the protagonist's increasing distress and the weight of his thoughts as he faces his fate. The focus on the sounds, such as the ticking of his watch, enhances the sense of time and impending doom, mirroring the mental turmoil and anxiety that Farquhar experiences in his final moments. This use of sensory language effectively conveys the psychological tension and the fragility of his state of mind.
