What types of attacks does the passenger and carry-on bag screening process deter or prevent?

• A. Reduce & deter Bombings & Hijackings
• B. Prevent all flights from being hijacked
• C. Eliminate all terrorist activity
• D. Detect all weapons with 100% accuracy.

Answer: (A)

Screening is a preventive measure that keeps dangerous items out of the passenger cabin and secure areas by inspecting carry-on bags and screening people. By increasing the effort and risk for someone attempting to bring weapons or explosives aboard, it reduces the likelihood of those threats being used to commit harm. This aligns with reducing and deterring bombings and hijackings, which is the most accurate summary of what these procedures aim to achieve. The other options imply absolutes the screening cannot guarantee—preventing all hijackings, eliminating all terrorist activity, or detecting weapons with 100% accuracy—so they don’t fit as well. In reality, screening is one layer of a broader security approach designed to lower risk rather than guarantee it.
