How can a teacher help the student make raising the flag easier?
By adding grease to the wheel of the pulley
By decreasing the size of the pulley
By increasing the length of the rope

Answer 1

A: By adding grease to the wheel of the pulley

Step-by-step explanation:

We know that it is not B (By decreasing the size of the pulley) because it would just make it harder for the student to do that task, by increasing the amount of force needed to complete the task. And we know it is not C (By increasing the length of the rope) because that would just give more rope to use, and not affect the amount of force needed. This leaves option A as the answer.
