Hello!
During the Great Depression, it was difficult for all races/social classes to find work. Unemployment rates were high and the economy was close to collapsing. Although all races and genders had a hard time finding work, unemployment rates for African Americans were higher than unemployment rates for whites. African Americans were discriminated against and their unemployment rate was nearly 20% higher than white workers.
The correct answer to your question is D: Unemployment rates among African Americans were higher than unemployment rates among whites.
I hope this answers your question!
