Consider the following premises. For all x_8, x_8 will not go running. There is at least one x_8 for which x_8 is a musician if and only if x_8 will drink water. For all x_8, x_8 will go running or x_8 is a musician. Can we infer the following from them? For all x_8, x_8 will not drink water.
 From the fact that there is at least one x_8 for which x_8 is a musician if and only if x_8 will drink water we can infer that there is at least one x_8 for which if x_8 were a musician, then x_8 is drinking water. From the fact that for all x_8, x_8 will go running or x_8 is a musician, and that for all x_8, x_8 will not go running we can infer that for all x_8, x_8 is a musician. Finally, from the fact that there is at least one x_8 for which if x_8 were a musician, then x_8 is drinking water, and that for all x_8, x_8 is a musician we can infer that there is at least one x_8 for which x_8 will drink water, which contradicts that For all x_8, x_8 will not drink water. Therefore, the answer is no.
