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: w -> t. ~Q_1(d_4) -> t. ~S_14(d_4). forall x_14: Q_1(x_14) <-> S_14(x_14).
forall x_14: Q_1(x_14) -> S_14(x_14) can be inferred via the universal biconditional elimination rule. forall x_14: S_14(x_14) -> Q_1(x_14) can be inferred via the universal biconditional elimination rule.
