Step-by-step explanation:
The federal legislation referred to in the excerpt resulted from economic challenges during the Great Depression. With the onset of the Great Depression in 1929, the United States faced record levels of unemployment and associated hardships, leading to a wave of federal reforms under President Franklin D. Roosevelt known as the New Deal. This period saw the creation of many new agencies and laws, such as the Federal Deposit Insurance Corporation, the National Labor Relations Board, and the Securities and Exchange Commission, which sought to revive the economy, stimulate development, and generate employment opportunities.
