In the excerpt from H. H. Munro's "Dusk," the details suggest that the theme of "People’s moods often change with the time of day" is supported. The text describes how the dusk setting affects the mood of Norman Gortsby, who finds harmony in the scene before him—a place where people with "shabby clothes and bowed shoulders" come out to hide their misfortunes and where the "hour of the defeated" is recognized. The atmosphere of dusk evokes a sense of introspection and sadness in the characters, highlighting how the time of day influences their emotional state.
Therefore, the correct response is:
People’s moods often change with the time of day.
