This paper tries to elucidate the paradoxical aspects of quantum mechanics (QM) by using a simplified pedagogical model of QM based on the support sets of the state vectors, by assuming an ontology of superposition-as-objective indefiniteness, and by not giving any ontological interpretation to the computational device of the wave function. The resulting realistic interpretation is the literal or objective indefiniteness interpretation. It has already been promoted by many quantum physicists using various terminologies, and it is assumed, at least implicitly, by any non-philosophical working quantum physicist who acknowledges that a particle in a superposition state for an observable does not have a definite value for that observable prior to a measurement.
