Answer:
The answer is the last option (“D”). The WPA helped revive the economy of Carbon Hill.
Step-by-step explanation:
Carbon Hill was a territory that suffered great effects from the economic "Depression" that began with the fall of Wall Street in 1929. Carbon Hill received resources from the Works Progress Administration (WPA) and the Public Works Administration (PWA). Both entities were created by the United States government during the Great Depression, as a way to help unemployed workers. Through funds, they promoted the hiring of skilled labor in public works projects. With temporary jobs they hired the residents of Carbon Hill to build a secondary school. Sewers, sidewalks and streets were also renovated.
