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 y_1: Q_1(y_1) or ~Q_3(y_1). exists y_1: Q_1(y_1) -> Q_3(y_1).
forall y_1: Q_3(y_1) -> Q_1(y_1) can be inferred via the universal rewriting rule.
