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_16: P_7(x_16) -> Q_7(x_16). forall x_16: ~P_16(x_16) or R_16(x_16). exists x_16: Q_7(x_16) -> Q_13(x_16). forall x_16: R_16(x_16) -> P_7(x_16). forall x_16: P_16(x_16) or W_3(x_16). forall x_16: W_3(x_16) <-> Q_13(x_16).
forall x_16: R_16(x_16) -> Q_7(x_16) can be inferred via the universal transitivity rule. exists x_16: P_7(x_16) -> Q_13(x_16) can be inferred via the existential transitivity rule. forall x_16: W_3(x_16) or R_16(x_16) can be inferred via the universal resolution rule. forall x_16: W_3(x_16) -> Q_13(x_16) can be inferred via the universal biconditional elimination rule. forall x_16: Q_13(x_16) -> W_3(x_16) can be inferred via the universal biconditional elimination rule.
