forces explain classic question

Can someone explain to me where is the pivot point when you are lifting the rear wheels off? Since the answer's logic makes sense but I cannot see how the distance of A to pivot is larger.

State and explain, without calculation, how the minimum force that needs to be applied
vertically at A to lift the rear wheels off the ground compares to the force you calculated in
part (c).
You may be awarded marks for the quality of written communication in your answer.

This is the answer:
force is less (1)
because distance to pivot is larger (1)
smaller force gives large enough moment (1)

Question 6?
The force would be applied at the handles (upwards) and the pivot would be the front wheels.

My bad, yes it is question 6. I see. I didn't know the force is applied upwards, I thought it meant a force is pushed down until the entire cart just leaves the floor. I get it now. Thank you!
