Use indirect truth tables to determine whether each set of propositions is consistent. If the set is consistent, choose an option with a consistent valuation. (There may be other consistent valuations.)
(E ⊃ F) ⊃ G
(~E ∨ F) ≡ (H ∨ I)
I ⊃ (J ⊃ ~H)
~G ⊃ ~J
(A)Inconsistent (B)Consistent. Consistent valuation when E is true and F, G, H, I, and J are false (C)Consistent. Consistent valuation when E and H are true and F, G, I, and J are false (D)Consistent. Consistent valuation when E and I are true and F, G, H, and J are false
