I got wheel and axle. I could picture the pulley but the word wouldn't come to mind. The others weren't even in considered. Good quiz. Not easy and I learned some things.
The screw, wedge and inclined plane are all the same principle. The threads of a screw are a continuous inclined plane. The principal of the lever is based on the assumption of using a real or imaginary fulcrum which is an applied wedge. The pulley is an application of the wheel and axle. I'd argue that there are only two unique machines the wedge and the wheeled axle but I am neither a machinist nor a Renaissance scientist so no one cares.
I think the distinction is in the way an initial force is changed by the machine. For a screw, the initial force is rotation. For an inclined plane it is straight line force which is diverted by the plane. A wedge divides a straight line force into two separate outward vectors. Similar difference applies to the wheel vs pulley.
What else is an incline if not an inclined plane? Seems like the same thing to me? If you accept just wheel then you should accept just incline I think
