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: T(y_1) -> ~P(y_1). exists y_1: P(y_1). forall y_1: T(y_1) or ~Q(y_1).
exists y_1: ~T(y_1) can be inferred via the existential modus tollens rule. forall y_1: Q(y_1) -> T(y_1) can be inferred via the universal rewriting rule.
