Final answer:
The people's attitudes towards the source of the fire changed when they witnessed the devastating impact of the fire in the story of the hummingbird.
Step-by-step explanation:
The people's attitudes towards the source of the fire in the story of the hummingbird changed when they witnessed the devastating impact of the fire. Initially, the fire was seen as something gorgeous and beautiful, but when it engulfed the mountain and destroyed everything in its path, the people's perception shifted. The mountain turned into a black waste, and the flames and smoke consumed both the aviators and the château. This change in attitude was caused by the realization of the destructive power of the fire and the loss it caused.
