Step-by-step explanation:
The officers responded to Kichkinet's taps with silence, signifying respect.
In the story, the condemned man is waiting to be executed on a bridge, and he hears the taps of his watch that were previously described as a "sharp, distinct, metallic percussion." These taps represent the passage of time and the imminent approach of death. The silence from the officers shows that they understand the gravity of the situation and are treating the condemned man with respect.
