What happens as Grandpa tells Alex and Zoe they need to leave the yacht immediately?

• A. They hear men talking / the engines start
• B. The alarm sounds
• C. A door locks
• D. A storm begins

Answer: (A)

When Grandpa tells them to leave, the most telling signals are the sounds of people nearby and the yacht starting to move. Hearing men talking outside shows an immediate human threat or pursuit, while the engines starting confirms that action is underway and they’re being propelled toward escape. These cues together create a sense of urgent, external danger and rapid movement, which is exactly what “leave immediately” is calling for.

The other options don’t fit the moment: an alarm could happen in a different scenario, but it isn’t the cue here; a door locking would keep them inside rather than push them toward leaving; a storm would shift the focus to weather rather than to people forcing them to flee.
