Consider the following premises. For all x_5, if x_5 were a police officer, then x_5 is not an astronaut. For all x_5, if x_5 drinks water, then x_5 is an astronaut. For all x_5, x_5 will drink water. For all x_5, x_5 will go running if and only if x_5 is a police officer. Can we infer the following from them? If we can, name the inference rule being used: For all x_5, if x_5 drinks water, then x_5 is an astronaut.
That is one of the premises. Therefore, the answer is yes.
