Which of the following is a common sign that a device might be present?

• A. A typical, everyday bag
• B. A bag with a boarding pass
• C. Unusual packaging, wires, or unfamiliar weight
• D. A known safe item

Answer: (C)

The idea is to recognize tangible, abnormal clues that something hidden might be present. Unusual packaging, visible wires, or an unfamiliar weight are concrete red flags you can observe on or around a device or bag. These signs go beyond normal appearance and handling and suggest that something inside could be nonstandard or dangerous, which is why they’re the best indicators.

An ordinary bag is common and expected, so it doesn’t raise suspicion by itself. A bag with a boarding pass doesn’t imply a device or tampering. A known safe item is trusted and not a warning sign. If you notice unusual packaging, wires, or an unfamiliar weight, treat it as a potential threat: avoid touching it, keep others away, and report it to security immediately.
