Final answer:
The curfew time cannot be precisely determined from the text, but it implies a period after midnight and before dawn (e.g., from somewhere around midnight to approximately 5 or 6 a.m.). A.M. designates the time before midday, and the narrative's description signals the early hours typically associated with curfews.
Step-by-step explanation:
The text presents a juxtaposition of two scenes showing time frames based on descriptive context, which is a common method to understand historical periods or events. The first one depicts a lively morning ambience, while the second one, Nighthawks, represents an indecent hour of night, indicating a time after midnight but before dawn, often associated with curfews.
Based on the provided excerpts, the specific times for the curfew cannot be distinctly determined. However, references to early morning activities and the context suggesting an environment on the cusp of bustling with life could imply curfews typically placed during the pre-dawn hours, often ranging from midnight to early morning (such as 5 or 6 a.m.). Without a precise time given in the excerpt, an exact curfew cannot be established. It is also important to recognize that a.m. stands for ante meridiem, which means 'before midday' and helps denote the time period before noon.
Historical texts sometimes include details that can help interpret events and lifestyles during certain eras, contributing to understanding societal norms such as curfews.
