Worked Solution

Step 1: On Earth, air resistance slows down light objects like feathers more than heavy ones. Step [2-9]: On the Moon, the lack of air means there is no air resistance. Step [2-9]: Without air resistance, gravity pulls all objects to accelerate at the same rate regardless of mass.

Correct answer: there is no air resistance to oppose their motion
