Consider the following premises. w_1 and q_14. forall x_23: U(x_23) -> S_23(x_23). U(a_23) or q_6. q_6 -> S_23(a_23). Can we infer w_1 and S_23(a_23) from them?
 From forall x_23: U(x_23) -> S_23(x_23) we can infer U(a_23) -> S_23(a_23). From w_1 and q_14 we can infer w_1. From U(a_23) -> S_23(a_23), q_6 -> S_23(a_23), U(a_23) or q_6 we can infer S_23(a_23). Finally, from w_1, S_23(a_23) we can infer w_1 and S_23(a_23). Therefore, the answer is yes.
