Consider the following premises. For all x_8, x_8 will not drink water. For all x_8, x_8 is a poet if and only if x_8 will take a plane. For all x_8, x_8 is a poet if and only if x_8 will drink water. For all x_8, x_8 will take a plane or x_8 is a server. Can we infer the following from them? There is at least one x_8 for which x_8 is not a server.
 From the fact that for all x_8, x_8 is a poet if and only if x_8 will drink water, and that for all x_8, x_8 will not drink water we can infer that for all x_8, x_8 is not a poet. From the fact that for all x_8, x_8 is a poet if and only if x_8 will take a plane, and that for all x_8, x_8 is not a poet we can infer that for all x_8, x_8 will not take a plane. Finally, from the fact that for all x_8, x_8 will take a plane or x_8 is a server, and that for all x_8, x_8 will not take a plane we can infer that for all x_8, x_8 is a server, which contradicts that There is at least one x_8 for which x_8 is not a server. Therefore, the answer is no.
