Final answer:
In Detroit at the time of the story, racial tension, housing issues, and labor unrest were significant concerns, aggravated by incidents like the Detroit riot and the Ford Hunger March, as well as the rise in crime during prohibition.
Step-by-step explanation:
The passage suggests that racial violence, housing shortages, and labor disputes were major sources of concern for people in Detroit at the time of the story. Incidents such as the attack on black families seeking to move out of designated black areas, the Detroit riot of 1943, and the Ford Hunger March of 1932 with its resulting casualties are clear indicators of significant social strife and unrest. Furthermore, issues related to the prohibition era, such as the rise in violence and crime facilitated by illegal bars known as speakeasies, widened the concern for public order and safety during this period.
