The most accurate response regarding the impact of the Great Depression on immigrants and African Americans is:
Racial discrimination and competition reduced work opportunities.
During the Great Depression, both immigrants and African Americans faced significant challenges, including racial discrimination that limited their access to jobs and resources. The economic downturn intensified competition for scarce jobs, often leading to increased hostility and exclusion against these groups. While some New Deal programs aimed to provide assistance, many were not equitably administered, and minorities often remained marginalized.
