Study the UML below. Explain the relation between all of the classes shown in the diagram, as

well as how they are used. Assume you are using this as a teaching example. For full credit,

you must discuss each class and mention how they fit into the whole.

Which class is called to run the program?

Where in inheritance taking place?

Where is aggregation taking place?

What is the relation between the class Shop and the class Product?

What are two significant differences about the class Product from all other classes and

what are the results of this?

Is good OOP being practiced here $-$ give two observations to support your answer Is polymorphism present why or why not?
