Question

Means allowing objects of different types to be considered as example of a higher level set.??

Answer 1

The correct answer is - Generalization.

A generalization is the formulation of general concepts from specific instances which are done by abstracting common properties of the objects.

Generalizations depict the existence of a domain or set of elements, as well as one or more common characteristics shared by those elements.

Generalization is the process of identifying the parts of an object as a whole, as belonging to the whole. The parts that are completely unrelated may be brought together as a group as a whole by establishing a common relation between them.
