While scanning devices like metal detectors or security cameras can detect potential threats. 

Explanation

 Security clearance is mandatory for sensitive government positions

Especially those involving access to classified information or secure facilities,

But it is generally not required for university admission, general medical exams, or driving licenses

Explanation

• Confidential: Could cause damage if disclosed.
• Secret: Could cause serious damage.
• Top Secret: Could cause exceptionally grave damage.
