Apply the generalization/specification for the following Central Zoo environment. Include all of the attributes and operations listed in the description. Central Zoo has three kinds of enclosures: cages, fenced areas, and water tanks. Each enclosure, regardless of which kind it is, has a unique enclosure number and a location. In addition, each cage has an area (in square feet or square meters), a height, and a type, each fenced area has an area and a fence height, each water tank has a temperature. Each water tank is composed of two parts, a tank (the zoo keeps track of the volume of the tank) and a pump (the zoo keeps track of the number of amperes of the pump.) Each animal that lives in a cage in the zoo has a unique animal number, a species, name, gender, and weight. Each cage can have several animals living in it or it can be empty. An animal can live in only one cage. There is an operation that calculates the next cleaning date of each enclosure, but this calculation is different for cages, fenced areas, and water tanks.
