What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x_4, x_4 will go running or x_4 will not drink water. For all x_4, x_4 will work if and only if x_4 will go running. There is at least one x_4 for which if x_4 goes running, then x_4 is drinking water. For all x_4, x_4 will not work.
For all x_4, if x_4 drinks water, then x_4 is running. For all x_4, if x_4 works, then x_4 is running. For all x_4, if x_4 goes running, then x_4 is working. For all x_4, x_4 will not go running.
