Draw an EER diagram for the situation described below. The diagram should show all necessary details, including entities, attributes, primary keys, relationships, and relationship cardinalities. Please state any reasonable assumptions clearly.

A rental car agency classifies the vehicles it rents into four categories: compact, midsize, full-size, and minivan. The agency wants to record the following data for all vehicles: VIN, Make, Model, Year, and Color. The entity type vehicle has a relationship (named Rents) with a customer entity type. The Rents relationship has the attributes Start_Date, End_Date, and Rental_Rate. Customers can be either general customers or belong to the frequent renter program. The frequent renter program assigns customers to levels of Diamond, Iron Ore, or Coal, depending on the number of rental points the customer has accumulated. Note that customers that do not belong to the frequent renter program are referred to being Dirt.
