1. prove that for an equivalence relation R on A, both sets, the class of equivalence classes of R-A/R— is a set. Specifically show that this follows by Principles 0-2 implicitly via the subclass-theorem. Hint. You will need, of course, to find a superset of A/R, that is, a class X that demonstrably is a set, and satisfies A/R CX.
