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_11 or q_11. w <-> p_2. p_2 -> ~t. q_11 -> t. p_11 -> t.
t can be inferred via the disjunction elimination rule. w -> p_2 can be inferred via the biconditional elimination rule. p_2 -> w can be inferred via the biconditional elimination rule.
