Consider the following premises. For all x_3, if x_3 were a sailor, then x_3 is running. For all x_3, x_3 will not drink water. There is at least one x_3 for which if x_3 goes running, then x_3 is a sailor. For all x_3, if x_3 were a sailor, then x_3 is drinking water. Can we infer the following from them? For all x_3, x_3 will go running.
 From the fact that for all x_3, if x_3 were a sailor, then x_3 is drinking water, and that for all x_3, x_3 will not drink water we can infer that for all x_3, x_3 is not a sailor. From the fact that for all x_3, if x_3 were a sailor, then x_3 is running, and that there is at least one x_3 for which if x_3 goes running, then x_3 is a sailor we can infer that there is at least one x_3 for which x_3 is a sailor if and only if x_3 will go running. Finally, from the fact that there is at least one x_3 for which x_3 is a sailor if and only if x_3 will go running, and that for all x_3, x_3 is not a sailor we can infer that there is at least one x_3 for which x_3 will not go running, which contradicts that For all x_3, x_3 will go running. Therefore, the answer is no.
