Answer: D) Poverty.
Explanation: The Great Depression was the worst economic downturn in the history of the industrialized world, lasting from 1929 to 1939. In "To Kill a Mockingbird" by Harper Lee, the setting is in the 1930s so they are in the time of the Great Depression, and there are many allusions to it, through mentions of poverty, for example, in the first chapter, Scout narrates that people in Maycomb are in no hurry because "there was nowhere to go, nothing to buy, and no money to buy it with."
