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.
