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, if x_8 sleeps, then x_8 is a politician. For all x_8, if x_8 were a sailor, then x_8 is a politician. For all x_8, x_8 is rich. For all x_8, if x_8 were rich, then x_8 is making tea. For all x_8, x_8 will sleep or x_8 is a sailor.
For all x_8, x_8 will make tea can be inferred via the universal modus ponens rule. For all x_8, x_8 is a politician can be inferred via the universal disjunction elimination rule.
