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: p_10 <-> p. q_1. ~p.
q_1 and ~p can be inferred via the conjunction rule. ~p and q_1 can be inferred via the conjunction rule. p_10 -> p can be inferred via the biconditional elimination rule. p -> p_10 can be inferred via the biconditional elimination rule. ~p_10 can be inferred via the biconditional elimination rule.
