What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: There is at least one x_12 for which x_12 will go running or x_12 will not drink water. For all x_12, x_12 will drink water or x_12 is a poet. For all x_12, if x_12 were a poet, then x_12 is running.
There is at least one x_12 for which if x_12 drinks water, then x_12 is running can be inferred via the existential rewriting rule.
