Heat keeps us warm, cooks our food, drives our engines, and in a thousand ways
makes life comfortable and pleasant, but what should we do without light? How
many of us could be happy even though warm and well fed if we were forced to live
in the dark where the sunbeams never flickered, where the shadows never stole
across the floor, and where the soft twilight could not tell us that the day was done?
Based on the passage, the author appears to believe that
heat is more important than light
light is more important than heat
neither heat nor light is important
light is as important as heat
