Can anybody help me with below four questions?
Problem a: What does the term polymorphism mean? Give an example.
Problem b: Use case models use two patterns - "Common Sub Behavior" and "Interrupts as Extensions." Explain these two patterns in your own terms and give an example for each pattern.
Problem c: The Pure Fabrication and Indirection patterns are often complementary. Support this statement using an example.

Solve these questions in details and provide examples to support your rationale.
