What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_10: ~P_10(x_10) or R_10(x_10). Q_2(i) -> r_2. forall x_10: P_10(x_10) or Q_2(x_10). R_10(i) <-> r_2.
R_10(i) -> r_2. r_2 -> R_10(i). forall x_10: Q_2(x_10) or R_10(x_10).
