What does overriding an inherited method mean in these Python examples?

• Deleting the parent's method for parent and child objects
• Defining a subclass version used for subclass objects
• Copying the unchanged parent method into every child object

TourBus inherits Vehicle. Its initializer calls Vehicle's initializer, then sets self.seats = 28. Vehicle initializes wheels and defines refuel. What does the resulting TourBus have?

• Initialized wheels and seats, plus inherited refuel
• Only initialized seats, with no inherited refuel method
• Initialized wheels and inherited refuel, but no seats

Vehicle defines refuel. Bus inherits Vehicle and does not define refuel. In this single-parent example, bus.refuel() uses Vehicle's version.

Inside a TourBus.refuel override, which expression calls the inherited Vehicle.refuel before adding receipt text?

• super().refuel(), then add the receipt text
• super(), then treat the proxy as the receipt text
• self.refuel(), then append the same receipt text

Bus overrides trip_info but inherits refuel from Vehicle unchanged. A Bus object calls both. Which definitions handle the calls?

• Vehicle trip_info and Vehicle refuel
• Bus trip_info and Bus refuel
• Bus trip_info and Vehicle refuel

Ferry(Vehicle) defines __init__ that calls super().__init__() and assigns self.decks. It also defines its own refuel. Which change does this implement?

• Adds self.decks and overrides refuel
• Adds a class attribute and inherits refuel unchanged
• Changes Vehicle itself and deletes its inherited methods

Bird.fly() promises actual flight. Penguin overrides it to return success without flying. Penguin is still a bird. Which design avoids making it promise flight?

• Keep the flight promise and return success without flying
• Keep Bird general and put flight in a flying subtype
• Keep the flight promise but rename Penguin's override

RoadVehicle promises that change_lane() moves between road lanes. An Airplane model supports only airborne travel. It is proposed as a RoadVehicle child to reuse trip_info. What is the problem?

• Sharing trip_info makes the road-lane contract optional
• Adding its own fields cancels inherited method promises
• Airplane cannot meet this road-only change_lane contract
