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