(pq) and then (ii) the truth table of the proposition pq (as in the previous problem, both truth tables in (i,ii) must reflect the process of building of a compound proposition at hand from propositional variables). (iii) Compare the truth tables, and make a conclusion on the equivalence of the propositions, thereby proving that (pq)pq (if your truth tables are not identical, redo the problem)
