Answer:
The little girl in the story was the wisest character because of the kindness she showed to the Chenoo.
Step-by-step explanation:
When the three brothers noticed the footprints in the North, South, and West, they disregarded it as the footprint of a bear. The girl in the story, however, believed that it was the Chenoo and she made provisions for it. She made a fire for it and prepared a meal for the Chenoo.
The monster was surprised at the welcome given by the little girl. This calmed him down and prevented him from attacking the girl and her brothers.
