Answer:
What motivates Ta-Ren-Ya-Wa-Gon to come to earth is:
C. He hears cries of suffering from the humans.
Explanation:
"Hiawatha the Unifier" is the story of how five great tribes came together to become the Iroquois people after being taught by Ta-Ren-Ya-Wa-Gon, or Hiawatha. The five tribes were originally one group of people taken care of and nourished by Hiawatha before he became mortal. He eventually separated them and taught them survival skills. Hiawatha then gave them names and different languages, as well as a different characteristic skill.
But, before all that took place, Hiawatha lived in the Heavens. What motivated him to come down to earth was the suffering of humans. He heard them cry and moan, choosing thus to come, teach and take care of them:
The slumber of Ta-Ren-Ya-Wa-Gon, the Upholder of Heavens, was disturbed by a great cry of anguish and woe.
He looked down from his abode to earth and saw human beings moaning with terror, pursued by horrifying monsters and cruel, man-devouring giants.
