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_5, x_5 is not a mechanic. For all x_5, x_5 is a police officer. For all x_5, x_5 is a mechanic or x_5 will make tea.
For all x_5, x_5 will make tea can be inferred via the universal disjunctive syllogism rule.
