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_14: W(x_14) <-> Q_14(x_14). forall x_14: Q_14(x_14). forall x_14: W(x_14) -> W_1(x_14).
exists x_14: W(x_14) -> Q_14(x_14) can be inferred via the existential biconditional elimination rule. exists x_14: Q_14(x_14) -> W(x_14) can be inferred via the existential biconditional elimination rule.
