The two responsibilities held by the federal government from the options provided are:
- Administering healthcare - The federal government administers various healthcare programs, such as Medicare and Medicaid.
- Providing Social Security - Social Security is a federal program that provides financial assistance to retirees, disabled individuals, and survivors.
The other options (protecting national parks, managing intercity traffic, creating garbage collection services, chartering city governments into existence) are more commonly associated with state or local governments rather than the federal government.
