Question 1 (10 marks) Consider the following description: An airline company has many planes and also many pilots (it can have no plane and no pilot initially). A plane is owned by one airline company and each pilot works for one airline company. Each pilot is responsible for driving one plane and a plane is driven by one to at most two pilots. Each passenger can take at most one plane at each time and each plane can be taken by zero or many passengers. A member of the pilots is selected as the representative who negotiates with an airline company. Each airline company is having one pilot as negotiator. Each pilot is supervised by a supervisor (who is also a pilot) and each supervisor can supervise three to five pilots. A pilot can be involved in zero or many incident histories and an incident history may be associated with one or two pilots. Using the notations of the textbook, complete the following ER diagram based on the above descriptions. You do not need to add new entity types but please state any assumptions needed.
