Final answer:
The New Deal's first act during FDR's initial 100 days focused on the banking crisis, with the Emergency Banking Act being a significant first step in a series of recovery and reform measures.
Step-by-step explanation:
During FDR's first "100 Days," the New Deal's first act to achieve recovery dealt with the banking crisis. An essential element of the New Deal focused on bank reform. The immediate action taken by Franklin D. Roosevelt after his inauguration was to address the banking crisis through the Emergency Banking Act, which aimed to restore consumer confidence by allowing federal agencies to examine all banks. This act was a pivotal part of a broader strategy that included recovery through relief and reform programs, affecting banks, farms, and providing jobs to counter the effects of the Great Depression.
