Consider the following premises. forall x_14: R_14(x_14) -> S_14(x_14). ~S_14(i_3). ~q_22. q_4 <-> q_22. Can we infer R_14(i_3) from them? If possible, name the inference rules being used at each step.
 From q_4 <-> q_22, ~q_22 we can infer ~q_4 via biconditional elimination. From forall x_14: R_14(x_14) -> S_14(x_14) we can infer R_14(i_3) -> S_14(i_3) via universal instantiation. Finally, from R_14(i_3) -> S_14(i_3), ~S_14(i_3) we can infer ~R_14(i_3) via modus tollens, which contradicts R_14(i_3). Therefore, the answer is no.
