What do the light and heat from the sun ripen?
They ripen the apples, cherries, and other fruits; also, the wheat, corn, and other grains, and make them fit for food.
When it is night-time or dark, can we distinguish objects?
No; because all things are then without color, and they cannot be seen.
As it grows light in the morning, what takes place?
At first, we see the objects around us faintly; but as it grows lighter, we see them more distinctly.
Do they all show the same color in the light?
They do not; they show different colors.
What enables us to see the color of different things?
Light enables us to see the color of everything.
