One of the oldest and largest pieces of social welfare policy in American history. In 2014, it costed the United States about $845 billion alone!

• A. Social Security
• B. Medicare
• C. Temporary Assistance for Needy Families
• D. Supplemental Security Income

Answer: (A)

The question tests recognizing a long-standing, large federal social welfare program funded by payroll taxes that provides broad benefits. Social Security fits this description: it began in 1935 and remains one of the biggest government programs in terms of outlays, covering retirement, disability, and survivors benefits for millions of Americans. The 2014 figure around $845 billion reflects its expansive reach. The other options are newer or more targeted—Medicare (health care for older adults) started later, and TANF and SSI are smaller, narrower programs—so Social Security is the best match for both age and scale.
