Answer to Question 1

When developing use cases, we may discover that some functionality has been left out: we expected the customer to pay by cash, but we find out that the business accepts credit cards as well. Instead of rewriting the use case, we can create an extending use case and add a conditional step to the base use case that branches to the new one if the customer decides to pay by credit card. This type of dependency is called an extend relationship and adds flexibility to maintaining use cases. The catch is that the normal outcome of the base use case must not depend on the success or failure of the extending use case.

Answer to Question 2

FALSE
