Consider the following premises. p <-> q_10. S_7(i_3) <-> q_10. ~p. forall x_7: R_7(x_7) <-> S_7(x_7). Can we infer ~R_7(i_3) from them?
 From p <-> q_10, ~p we can infer ~q_10. From forall x_7: R_7(x_7) <-> S_7(x_7) we can infer R_7(i_3) <-> S_7(i_3). From S_7(i_3) <-> q_10, ~q_10 we can infer ~S_7(i_3). Finally, from R_7(i_3) <-> S_7(i_3), ~S_7(i_3) we can infer ~R_7(i_3). Therefore, the answer is yes.
