What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: Q_10(a_8) <-> q_4. ~q_4. forall x_10: ~P_10(x_10) or R_10(x_10). forall x_10: P_10(x_10) or Q_10(x_10).
Q_10(a_8) -> q_4 can be inferred via the biconditional elimination rule. q_4 -> Q_10(a_8) can be inferred via the biconditional elimination rule. ~Q_10(a_8) can be inferred via the biconditional elimination rule. forall x_10: Q_10(x_10) or R_10(x_10) can be inferred via the universal resolution rule.
