Answer each of the following. Be consise! Put your answers in a file called shortanswers.txt (a plaintext file) or shortanswers.pdf. (A) Suppose users in discord are modelled with a User class. Each user in discord can different roles assigned to it. For example, you all have the Student role. Each role has a different behaviour (i.e., what content you can access, what you can do in various channels, etc.). Explain why making each role a subclass of the User class is not a good idea. (B) Suppose you are implementing a chess game. Explain why having an abstract ChessPiece class and several concrete subclasses (Pawn, Queen, Rook, etc) is a good idea.
