Which of the following interventions was part of the New Deal?

The Works Progress Administration (WPA) was a key intervention of the New Deal, established in 1935 to combat the massive unemployment resulting from the Great Depression. The WPA aimed to provide jobs for millions of Americans by funding various public works projects, which included the construction of roads, bridges, schools, and parks. It also supported artists, writers, and musicians, thereby enriching American culture while stimulating economic recovery. This program was instrumental in helping to restore dignity and financial stability to many families during the economic crisis.

The other options listed, while significant in their own contexts, were not part of the New Deal. The Military Accountability Act pertains to different legislative themes unrelated to economic recovery efforts of the 1930s. The Homestead Act was a piece of legislation from the 19th century designed to promote westward expansion by providing land to citizens willing to settle it, predating the New Deal. The Fair Labor Standards Act focused on establishing minimum wage and maximum working hours, but it was enacted in 1938, after many key New Deal programs had been introduced.
