(1 point)
She did not measure the circumference of the balls.
She dropped the balls from different heights.
She used balls that are different sizes.
She did not measure the mass after the balls hit the ground.

She used balls that are different sizes.
Reason: The times should be nearly the same regardless of mass if dropped from the same height. The longer time for the 26 g ball suggests different air resistance (due to size/shape), so using balls of different sizes is the likely source of error.
