Consider the following premises. There is at least one x_8 for which if x_8 were a server, then x_8 is drinking water. For all x_8, if x_8 were a taxi driver, then x_8 is drinking water. For all x_8, if x_8 cooks, then x_8 is not drinking water. For all x_8, x_8 is a taxi driver or x_8 is a server. Can we infer the following from them? There is at least one x_8 for which x_8 will not cook.
 From the fact that for all x_8, if x_8 were a taxi driver, then x_8 is drinking water, that there is at least one x_8 for which if x_8 were a server, then x_8 is drinking water, and that for all x_8, x_8 is a taxi driver or x_8 is a server we can infer that there is at least one x_8 for which x_8 will drink water. Finally, from the fact that for all x_8, if x_8 cooks, then x_8 is not drinking water, and that there is at least one x_8 for which x_8 will drink water we can infer that there is at least one x_8 for which x_8 will not cook. Therefore, the answer is yes.
