The Answer of 1. (P $ \lor $ Q) $ \lor $ R
2. ∼(S $ \lor $ Q)
-Which of the following propositions is an immediate (one-step) consequence in PL of the given premises?
A) ∼S $ \lor $ ∼Q
B) ∼S • ∼Q
C) ∼Q • ∼S
D) (P $ \lor $ R) $ \lor $ Q
E) Q $ \lor $ (P $ \lor $ R)

1 (P ∨ \lor ∨ Q) ∨ \lor ∨ R 2 ∼(S ∨ \lor ∨
