Answer:
The best answer to the question: Why did the husband become "terrified", from the answer choices given here, would be: He was terrified he would be punished for marring the sacred tree.
Step-by-step explanation:
Although the direct answer given by the Iroquois Myth of Creation, is that the man became "terrified" because: "he had never expected to find empty space underneath the world", the myth also states that the man did not like his wife´s insistence that he get bark from the roots of the tree, because it was a sacred one, and it was forbidden to mark, or mutilate, the tree by any of the dwellers of the Sky-World. Given that, and taking the answer choices, the choice given above would be the closest correct option.
