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_10 or r. ~t. t <-> q_10.
t -> q_10 can be inferred via the biconditional elimination rule. q_10 -> t can be inferred via the biconditional elimination rule. ~q_10 can be inferred via the biconditional elimination rule.
