Consider the following premises. forall x_6: ~W(x_6). forall x_6: W(x_6) or Q(x_6). forall x_6: Q(x_6) -> R_2(x_6). exists x_6: W_4(x_6). Can we infer exists x_6: W_4(x_6) and R_2(x_6) from them?
 From forall x_6: W(x_6) or Q(x_6), forall x_6: ~W(x_6) we can infer forall x_6: Q(x_6). From forall x_6: Q(x_6) -> R_2(x_6), forall x_6: Q(x_6) we can infer forall x_6: R_2(x_6). Finally, from exists x_6: W_4(x_6), forall x_6: R_2(x_6) we can infer exists x_6: W_4(x_6) and R_2(x_6). Therefore, the answer is yes.
