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: T(y) -> P(y). exists y: W_4(y) -> T(y). forall y: P(y) -> W_4(y).
forall y: T(y) -> W_4(y) can be inferred via the universal transitivity rule. exists y: W_4(y) -> P(y) can be inferred via the existential transitivity rule. exists y: P(y) -> T(y) can be inferred via the existential transitivity rule.
