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_2 and q_7. forall x_23: P_23(x_23) and Q_23(x_23).
q_2 can be inferred via the simplification rule. q_7 can be inferred via the simplification rule. forall x_23: P_23(x_23) can be inferred via the universal simplification rule. forall x_23: Q_23(x_23) can be inferred via the universal simplification rule.
