2. Complete the following text using words from the reading text:

Encapsulation, inheritance and polymorphism are key features of object-oriented programming. Encapsulation allows data and program instructions to be bundled together in modules called objects. Inheritance means that specific instances of a class of objects inherit the properties of the class of objects. Polymorphism means that instructions are treated differently by different objects the combination of these key features of OOP means that program code is reusable. This speeds up development and maintenance of programs.
