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 x_16: Q_16(x_16) -> W_4(x_16). forall x_16: Q_2(x_16) or T_2(x_16). forall x_16: W(x_16). forall x_16: W_1(x_16). forall x_16: Q_2(x_16) -> W_4(x_16). forall x_16: T_2(x_16) -> Q_16(x_16).
exists x_16: T_2(x_16) -> W_4(x_16) can be inferred via the existential transitivity rule. forall x_16: W(x_16) and W_1(x_16) can be inferred via the universal conjunction rule. forall x_16: W_1(x_16) and W(x_16) can be inferred via the universal conjunction rule.
