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 x_6: W_3(x_6) -> W(x_6). forall x_6: W(x_6) -> W_3(x_6). forall x_6: W(x_6) -> P_5(x_6). forall x_6: P_5(x_6) -> W(x_6). forall x_6: ~P_5(x_6).
forall x_6: ~W(x_6) can be inferred via the universal modus tollens rule. forall x_6: W_3(x_6) -> P_5(x_6) can be inferred via the universal transitivity rule. forall x_6: P_5(x_6) -> W_3(x_6) can be inferred via the universal transitivity rule. forall x_6: W_3(x_6) <-> W(x_6) can be inferred via the universal biconditional introduction rule. forall x_6: W(x_6) <-> W_3(x_6) can be inferred via the universal biconditional introduction rule. forall x_6: W(x_6) <-> P_5(x_6) can be inferred via the universal biconditional introduction rule. forall x_6: P_5(x_6) <-> W(x_6) can be inferred via the universal biconditional introduction rule.
