Why are "quizzes" different from the examples?

Question

Currently, I'm looking to solve the last question found in the constructor module and I don't see any similarities with the examples we were given. This is not the first time either. Am I the only one lost here?

Answer 1

The questions have to be different. To show you have learned, you have to show you can generalize from the given examples.

Answer 2

why not?

Answer 3

What I mean is that the idea being tested often is not the same idea that was taught. This is what I've noticed.
