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_1(y) or ~W(y). forall y: R(y) -> W(y). forall y: U(y) -> R(y).
forall y: U(y) -> W(y) can be inferred via the universal transitivity rule. forall y: W(y) -> T_1(y) can be inferred via the universal rewriting rule.
