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: For all x_8, x_8 is bored or x_8 will not drink water. For all x_8, if x_8 were bored, then x_8 is sleeping. There is at least one x_8 for which if x_8 were an electrician, then x_8 is sleeping. For all x_8, x_8 will drink water.
For all x_8, if x_8 drinks water, then x_8 is bored can be inferred via the universal rewriting rule.
