Which event most contributed to this phenomenon described in this
passage?
We are now in a position to see clearly some of the factors
involved in the Western problem. For nearly three centuries
the dominant fact in American life has been expansion.
With the settlement of the Pacific coast and the
occupation of the free lands, this movement has come to a
check. ... [T]he restless, rushing wave of settlement has
broken with a shock against the arid plains. The free lands
are gone, the continent is crossed, and all this push and
energy is turning into channels of agitation.
---Frederick J. Turner, "The Problem of the West," 1896
A. The formation of the Immigration Restriction League
B. The passage of the Indian Removal Act
C. The completion of the Transcontinental Railroad
D. The end of Reconstruction in the South

no

explanation:

not everyone in america is free. it is has always been a unequal society. and yet people come in swarms, in search of better lives. some are brought as children, unaware, unknowing. some arrive and just don’t leave. they build lives, pay taxes, raise families. some enter illegally, fleeing persecution in their home country.

there are many reasons why human beings are so attracted to america, despite its history of bitterness towards immigrants.

there are almost two million immigrants brought to the us when they were children. president donald trump and his collaborators are determined to rid the us of as many undocumented immigrants as they can, and stop others from coming because none of their ancestors were immigrants.

america has so many things and yet it lacks the one thing that humanity needs to fully thrive. and so this country will not be at peace in itself until it resolves the pain at the heart of slavery, attacking immigrants, and crumble the rights of those with less power.
