Consider the following premises. There is at least one x_15 for which if x_15 were a soldier, then x_15 is curious. For all x_15, if x_15 were curious, then x_15 is driving a car. For all x_15, if x_15 were a nurse, then x_15 is a soldier. For all x_15, x_15 is a nurse if and only if x_15 will drive a car. Can we infer the following from them? If we can, name the inference rule being used: For all x_15, x_15 is a nurse if and only if x_15 will drive a car.
That is one of the premises. Therefore, the answer is yes.
