The excerpt suggests that the Iroquois believed that:
sometimes good can come from tragedy.
Explanation:
The excerpt in question is part of a creation myth by the Iroquois, a group of Native-American tribes. According to it, tragedy can give birth to blessings. The death of "our mother" gave origin to plants whose existence would be crucial for the survival of the Iroquois people: corn, beans, squash, and tobacco. Death does not cease to be a tragic event. It still brings sadness and loss into people's lives. But the myth uses it to show that, however bad things may seem, something good may come out of it.
