2- Consider the use case "Sell vehicle" presented in the next page. Create a sequence diagram and a communication diagram to model the realization of this use case. 3- Create a state machine diagram for the class Vehicle. Hints for the state machine diagram: scenario information does not provide many details about processes involving a vehicle, so you have to come up with a reasonable set of states based on your assumptions. Here are some suggestions about these processes that could lead to identifications of states: a vehicle could be on transit to the dealership, could be on display at the dealership or available in inventory, the vehicle could be detailed or serviced before sale or after sale before the customer picks it up, the vehicle could be made temporarily unavailable for sale while a customer is negotiating the sale price or a customer could make a deposit to reserve the vehicle until they are able to visit the dealership to test drive it, and finally a vehicle is sold.
