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_9, x_9 is an electrician or x_9 will not make tea. For all x_9, x_9 will make tea or x_9 is not an electrician.
For all x_9, if x_9 makes tea, then x_9 is an electrician can be inferred via the universal rewriting rule. For all x_9, if x_9 were an electrician, then x_9 is making tea can be inferred via the universal rewriting rule.
