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_1 -> p_10. p_10 <-> q_1. q_1 or q. ~p_10.
~q_1 can be inferred via the modus tollens rule. p_10 -> q_1 can be inferred via the biconditional elimination rule. q_1 -> p_10 can be inferred via the biconditional elimination rule. ~q_1 can be inferred via the biconditional elimination rule.
