Step-by-step explanation:
B. Competition for resources among White settlers and American Indians.
The advice in the excerpt encourages people to take advantage of the government's policies to settle in the West in order to acquire land and resources. This led to competition between white settlers and American Indian tribes for land and resources.
As more white settlers moved westward, they increasingly encroached on land that had previously been held by American Indian tribes, leading to conflict over the control of resources. This competition for resources ultimately resulted in the displacement of many American Indian tribes from their ancestral lands.
