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 z: ~W(z) or U_2(z). q_1 -> t. T(c) -> q_1. forall z: W(z) or T(z). U_2(c) -> t.
T(c) -> t can be inferred via the transitivity rule. forall z: T(z) or U_2(z) can be inferred via the universal resolution rule.
