Final answer:
The Social Security Act of 1935 changed the social contract, provided the foundation for Medicare and Medicaid, and included benefits for unemployed workers and victims of industrial accidents.
Step-by-step explanation:
The Social Security Act of 1935 accomplished options 1, 2, and 4. It changed the social contract between the federal government and US citizens by establishing a system of old-age pensions funded by taxes paid by employers and employees.
The act also provided the foundation for Medicare and Medicaid by creating a program to pay the medical expenses of those over sixty-five, and it included benefits for unemployed workers and industrial accident victims, and direct payments to the one who is above the age of 65.
