Part A
The theme in the poem that is most relevant is:
2. People adapt to different ways of life and survive.
Part B
The two lines from the poem that best support the correct answer from Part A are:
2. "The feathers, paint and moccasin will vanish, but the Indians, never!" (Line 3)
4. "He is an industrial and commercial man, competing with the world; he has not vanished." (Line 7)
These lines illustrate how, while some traditional aspects of Indian culture may change or disappear, the people themselves persist and continue to adapt to the modern world.
