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_15 or ~W_1(h). ~q. q <-> q_15. forall x_12: W_1(x_12) <-> S_12(x_12).
W_1(h) -> q_15 can be inferred via the rewriting rule. q -> q_15 can be inferred via the biconditional elimination rule. q_15 -> q can be inferred via the biconditional elimination rule. ~q_15 can be inferred via the biconditional elimination rule. forall x_12: W_1(x_12) -> S_12(x_12) can be inferred via the universal biconditional elimination rule. forall x_12: S_12(x_12) -> W_1(x_12) can be inferred via the universal biconditional elimination rule.
