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_17. t <-> q_17. p -> ~q. ~t -> q.
t -> q_17 can be inferred via the biconditional elimination rule. q_17 -> t can be inferred via the biconditional elimination rule. ~t can be inferred via the biconditional elimination rule.
