The responsibilities of the Department of Health and Human Services (HHS) include:
- To provide services such as Medicare and Medicaid: HHS administers these programs to ensure access to health care for eligible populations, including the elderly, low-income individuals, and certain disabled persons.
The other options mentioned are not primary responsibilities of HHS:
- The responsibility to provide research and protection against environmental pollutants is typically more aligned with the Environmental Protection Agency (EPA).
- Monitoring and ensuring the enforcement of federal civil rights is mainly the responsibility of the Department of Justice (DOJ), though HHS has a role in health-related civil rights enforcement.
- Providing Social Security benefits is managed by the Social Security Administration (SSA), not HHS.
Thus, the best answer is the third option regarding Medicare and Medicaid.
