After the yacht sinks, which predator does Grandpa say he is worried about?

• A. Alex's mother
• B. A hungry shark
• C. A lurking alligator
• D. The dolphins

Answer: (A)

This question checks your ability to identify who is described as a predator in the moment and to recognize when the danger comes from a person rather than wildlife. After the yacht sinks, the text has Grandpa express concern about a specific person, naming Alex's mother as the predator. That direct statement shows the danger is human and personal, not an animal threat. The other options—shark, alligator, or dolphins—are plausible wildlife threats one might expect, but they’re not the worry Grandpa voices in that scene. So the best answer is the one that matches the exact person Grandpa mentions.
