Consider the following premises. forall x_16: R_16(x_16) or S_16(x_16). q_2 <-> r. q_2 or ~S_16(a_16). ~R_16(a_16) or r. Can we infer q_2 from them?
 From forall x_16: R_16(x_16) or S_16(x_16) we can infer R_16(a_16) or S_16(a_16). From q_2 or ~S_16(a_16) we can infer S_16(a_16) -> q_2. From R_16(a_16) or S_16(a_16), ~R_16(a_16) or r we can infer S_16(a_16) or r. From q_2 <-> r we can infer r -> q_2. Finally, from S_16(a_16) -> q_2, r -> q_2, S_16(a_16) or r we can infer q_2. Therefore, the answer is yes.
