Consider the following premises. ~U_2(a_14). forall x_14: U_2(x_14) and S_14(x_14). Can we infer q_2 from them?
 From forall x_14: U_2(x_14) and S_14(x_14) we can infer U_2(a_14) and S_14(a_14). From U_2(a_14) and S_14(a_14) we can infer U_2(a_14). From U_2(a_14) we can infer U_2(a_14) or q_2. Finally, from U_2(a_14) or q_2, ~U_2(a_14) we can infer q_2. Therefore, the answer is yes. Notice, however, that the premises were contradictory, so we can infer anything from them.
