For the question “which one of these does not pose a risk to security at a government facility,” the option that would not pose a risk is the one describing a properly authorized, controlled, and compliant activity (for example, an employee following all access-control rules and wearing a valid badge in a designated public or low‑risk area).

Common things that do pose risks at government facilities include:

  • Unauthorized access or tailgating into secure areas
  • Terrorism and bomb threats
  • Civil unrest, rioting, or violent protests
  • Theft, vandalism, and sabotage
  • Insider misuse of access or data
  • Cyber attacks on government networks and systems

So, in a typical multiple‑choice context, the correct answer is the option that describes normal, authorized, policy‑compliant behavior (for example, a cleared staff member using their badge correctly), because that does not introduce a new security risk by itself.
