The action of the speaker that can be considered ironic is that actually the speaker takes initiative of establishing the wall up to himself but then he questions it and has some doubts about that. There is another irony, I would say, the main one, you may find it useful : the wall which was meant to separate neighbours brings them together every year in order to repair it. Is it really the borderline?Hope that helps.
Is this for a novel? Please explain more
Answer:
C. Ontological
Explanation:
Metaphysics itself is a branch of philosophy that advocates beyond physical or abstract concepts and ontology is a sub-branch of metaphysics dealing with the nature of being or existence. It focuses on the concepts related to human existence and their relations. It questions the objective reality and attempts to find the meanings of being. for example, Plato and Aristotle both proposed their ontological theories, the former gave the distinction between the true reality and illusion while the latter provided the existence of ten different kinds of beings.
