Draw a class diagram for the following scenario. Make sure to show proper multiplicity and attributes. Indicate different types of property listing using generalization.

Each real estate agent works for one real estate office. Information about agent includes name, desk phone number, and email. Information about each real estate office includes office name, address, and phone number.

Real estate agents use the Multiple Listing Service (MLS) listing to help their customers sell houses or commercial properties. Information that the agent posts on the MLS listing includes the address, asking price, and status code (i.e., active, under contract, or sold). For houses, additional info includes the number of bedrooms; for commercial properties, additional info includes zoning and occupancy. Under the contract, each seller works exclusively with one agent.
