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: R_14(a_14) <-> t_1. forall x_14: ~R_14(x_14). r.
R_14(a_14) -> t_1 can be inferred via the biconditional elimination rule. t_1 -> R_14(a_14) can be inferred via the biconditional elimination rule.
