Consider the following premises. There is at least one x_9 for which x_9 will not drink water. For all x_9, x_9 is a soldier if and only if x_9 is an artist. For all x_9, if x_9 drinks water, then x_9 is an artist. For all x_9, if x_9 were an artist, then x_9 is drinking water. Can we infer the following from them? If we can, name the inference rule being used: There is at least one x_9 for which x_9 will not drink water.
That is one of the premises. Therefore, the answer is yes.
