Question

5.) The author tells us that the boy's sister's eyes widened when hearing about

the porpoises. Why?

Answer 1

Because porpoises are beautiful, majestic creatures of the sea!

Step-by-step explanation:

When someone's eyes are wide, it can mean one of two things; 1) they are scared, 2) they are amazed. In the context of the sentence provided, the girl must be amazed, because the topic of discussion is porpoises, not clowns or some other frightening subject.

Here's a picture of a porpoise. They look very similar to dolphins.
