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: forall x_8: Q_1(x_8). exists x_8: Q_3(x_8) and Q_8(x_8).
exists x_8: Q_3(x_8) can be inferred via the existential simplification rule. exists x_8: Q_8(x_8) can be inferred via the existential simplification rule.
