Inclined Plane as a non-ideal machine (EK in-class question)

This question is about a NON-ideal inclined plane being used to lift a crate to 3 ms of height. The question (Question #83, UNit 4 Physics) asks which of the statements are true, and based on the answer key, the correct answer is : "The non-ideal inclined plane decreases the F required and increases W"

I understand why the Work increases, as a non-ideal inclined plane has frictional forces to be overcome. But by the same token, doesn't the force required also increase? Why is the force decreasing??

Im not sure to the answer because i dont have the question in front of me, but I believe its comparing different types of ramps to no ramps? maybe?

If so, then having no ramp will make a person lift the block straight up in the y coordinate plane. When you add a ramp, it adds a partial x coordinate as well as the partial y coordinate dispersing some of the force, thus causing the force to decrease when compared to no ramp.

if you add the full question/choices, it would help!

You aren't comparing the force with a non-ideal plane vs the force on an ideal plane.

You are comparing the force of a non-ideal plane vs the force when there is no plane at all.

Thanks you, that makes sense.
