Final answer:
In response to the Great Depression, the U.S. New Deal programs, specifically the Social Security Act of 1935, provided retirement benefits, unemployment insurance, and support for vulnerable citizens.
Step-by-step explanation:
The United States, during the administration of President Franklin D. Roosevelt, addressed the severe economic and social issues of the Great Depression through the creation of the New Deal programs. Among these, the Social Security Act of 1935 stands out as a landmark legislation that established a system of retirement benefits for the elderly, unemployment insurance, and aid for the most vulnerable populations. The passage of the Social Security Act and other New Deal programs such as the Work Progress Administration and Civilian Conservation Corps, helped to create a social safety net, reduce unemployment, and catalyze economic recovery.
