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: t -> T_4(j). t <-> p_4. forall z_2: ~T_4(z_2).
t -> p_4 can be inferred via the biconditional elimination rule. p_4 -> t can be inferred via the biconditional elimination rule.
