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, if x_9 were curious, then x_9 is a cashier. For all x_9, if x_9 were a cashier, then x_9 is poor. For all x_9, x_9 is curious or x_9 is not poor.
For all x_9, if x_9 were curious, then x_9 is poor can be inferred via the universal transitivity rule. For all x_9, if x_9 were poor, then x_9 is curious can be inferred via the universal rewriting rule.
