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: q -> W(a_10). forall x_14: P_14(x_14) <-> W(x_14). u -> q.
u -> W(a_10) can be inferred via the transitivity rule. forall x_14: P_14(x_14) -> W(x_14) can be inferred via the universal biconditional elimination rule. forall x_14: W(x_14) -> P_14(x_14) can be inferred via the universal biconditional elimination rule.
