Who stopped the Millennium bomber?

• A. FBI agent
• B. TSA inspector
• C. A flight attendant
• D. CBP officer Dean

Answer: (D)

The key idea being tested is which security role is depicted as stopping a threat on a flight and what authority that role has in aviation security. In this scenario, a Customs and Border Protection officer named Dean is the one who stops the Millennium bomber. This matters because CBP officers operate in the realm of international and border-related aviation security, and the scenario assigns the decisive action to a federal officer rather than just the cabin crew or investigators. It illustrates how different agencies fit into the chain of response: flight attendants and passengers are essential for immediate restraint, but the formal stop and custody action in this context is shown as coming from a CBP officer, with the FBI typically handling post-incident investigation and TSA focusing on screening operations rather than in-flight intervention.
