2. Carla's favorite ball is bright blue when it is outside in the direct sunlight. Inside, the ball
appears to be almost green. Why does Carla's ball seem to change colors?
A. Color is determined by the density of an object, and Carla's ball became more dense when
she went inside out of the sunlight.
B. Color is determined by the size of an object, and Carla's ball lost air while being played
with, so it was smaller when she went inside.
C. Color is determined by the wavelength of light reflected or absorbed by the object, and the
light changed when Carla went inside.
D. Color is determined by the temperature of an object, and the temperature changed when
Carla went inside out of the sunlight.
