This pair of photographs suggests that the major purpose of the Carlisle Indian School was to train future leaders in tribal traditions

prepare children for life on the reservation

promote cultural assimilation

teach skills needed for working in factories

The correct answer is to Promote cultural assimilation

Explanation:

In the first photograph, children at the Carlie Indian School are wearing traditional Native American clothes, and boys have long hair, which was considered as normal in Native American Tribes. These features disappeared in the second photo because in this, boys have short hair and all the children are wearing similar clothes. Moreover, these clothes do not resemble the tribe's clothes but Europeans or colonizers' clothes.

This shows the children have acquired values, ideas, practices, etc. of colonizers, while forgetting about traditional values, ideas, practices, etc. This process is known as cultural assimilation and implies minorities adapt to the main culture by adopting cultural elements of this culture.
