Answer:
1. To her Husband, Aataentsic's actions were heroic because she risked everything to save his life.
To the people of Sky Land, she may be considered a villian worthy of the worst punishment. She jeopardised the source of sustenance of the entire Sky Land for one man - her husband.
2. According to the story, the Sky Tree is a great tree which could be found in the middle of the Sky Land.
The Sky Tree is important to the people of Sky Land because all the food they ate came from it.
3. Aataentsic chose to cut down the tree because in the dream she had about her sick husband, her husband had instructed her to cut the tree and give him the fruit which grows at it's very top. This is the only way he would be healed.
This action reveals that she was very fond of her husband and would have given anything to see him live.
4. The animal which observed Aataentsic's fall is a Turtle.
The Turtle spearheaded the rescue mission which saved Aataentsic's life and the tree by helping her land safely on its back which with the help of the other animals was not covered with earth.
5. Animals in our culture mean many things to many people. To some, animals are food. To some, they have life and deserve to be preserved and treated with kindness. Biologically speaking, however, animals form an important part of our ecosystem. Unlike the myth, animals in real life are incapable of executing such an organised rescue mission.
