Answer: One piece of evidence from the period 1929-1939 that could support the interpretation that the New Deal was effective in reducing the impact of the Great Depression is the decrease in the unemployment rate during that period. While the excerpts do not mention this explicitly, the unemployment rate decreased significantly from its peak of 25% in 1933 to 14% in 1937. This decline can be attributed to several New Deal policies that aimed to create jobs and stabilize the economy, such as the Civilian Conservation Corps (CCC) and the Works Progress Administration (WPA). These programs provided employment opportunities for millions of Americans, which not only reduced unemployment but also stimulated consumer spending and economic growth. Therefore, the decrease in the unemployment rate can be seen as evidence that the New Deal was effective in mitigating the impact of the Great Depression.
