The Moon has practically no atmosphere, so there is no air resistance.

The Moon’s gravity is much weaker than Earth’s.
The Moon’s gravity is much weaker than Earth’s.

The pieces of paper were not dropped from a sufficient height for air resistance to affect their falls.

Answer 1

The correct response is:

The Moon has practically no atmosphere, so there is no air resistance.

On the Moon, the lack of atmosphere means there is no air resistance to slow down either piece of paper, allowing both to fall at the same rate and land at the same time despite their different shapes.
