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_12, if x_12 works, then x_12 is making tea. If Robert works, then Michael is running. For all x_12, x_12 will work or x_12 will not make tea.
For all x_12, if x_12 makes tea, then x_12 is working can be inferred via the universal rewriting rule.
