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_11, x_11 will cook. For all x_11, x_11 will not climb a mountain or x_11 is curious. For all x_11, if x_11 were curious, then x_11 is driving a car. For all x_11, x_11 will climb a mountain or x_11 is a nurse. There is at least one x_11 for which if x_11 were a nurse, then x_11 is driving a car.
For all x_11, x_11 is a nurse or x_11 is curious can be inferred via the universal resolution rule.
