Consider the following premises. forall z: ~W_1(z). forall z: W_1(z) or W_3(z). exists z: R(z). Can we infer exists z: R(z) and W_3(z) from them?
 From forall z: W_1(z) or W_3(z), forall z: ~W_1(z) we can infer forall z: W_3(z). Finally, from exists z: R(z), forall z: W_3(z) we can infer exists z: R(z) and W_3(z). Therefore, the answer is yes.
