Consider the following premises. p_4 <-> S_10(a_10). forall x_10: R_10(x_10) -> S_10(x_10). p_4 or R_10(a_10). Can we infer S_10(a_10) from them?
 From forall x_10: R_10(x_10) -> S_10(x_10) we can infer R_10(a_10) -> S_10(a_10). From p_4 <-> S_10(a_10) we can infer p_4 -> S_10(a_10). Finally, from p_4 -> S_10(a_10), R_10(a_10) -> S_10(a_10), p_4 or R_10(a_10) we can infer S_10(a_10). Therefore, the answer is yes.
