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: If Richard works, then James is playing tennis. For all x_17, if x_17 plays tennis, then x_17 is making tea. James is playing tennis or James is not making tea.
If James makes tea, then James is playing tennis can be inferred via the rewriting rule.
