Which two cues signal danger during departure?

• A. They hear men talking / the engines start
• B. The lights go out
• C. A siren sounds
• D. A crew member shouts

Answer: (A)

Danger in this situation comes from spotting a combination of intent and action as someone tries to leave. Hearing people talking suggests planning or collusion about departing, which signals potential danger if the plan is hostile or unlawful. The engines starting provides a concrete action showing that departure is underway. When these two cues appear together, they point to an imminent, coordinated departure, which is a stronger warning than any single cue on its own.

Other signals like lights going out, a siren, or a crew member shouting can indicate trouble, but they don’t directly combine to indicate that a deliberate departure is in progress. The pairing of suspicious discussion and the engines starting best explains imminent danger during departure.
