What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_13: P_10(x_13) or P(x_13). forall x_13: P(x_13) <-> W_2(x_13). forall x_13: ~P_10(x_13) or R_2(x_13). forall x_13: R_2(x_13) <-> W_2(x_13).
forall x_13: P(x_13) or R_2(x_13). forall x_13: P(x_13) -> W_2(x_13). forall x_13: R_2(x_13) -> W_2(x_13). forall x_13: W_2(x_13) -> P(x_13). forall x_13: W_2(x_13) -> R_2(x_13).
