Question

Up to our own day American history has been in a large degree the history of the colonization of the Great West. The existence of an area of free land, its continuous recession, and the advance of American settlement westward, explain American development...

The peculiarity of American institutions is, the fact that they have been compelled to adapt themselves to the changes of an expanding people—to the changes involved in crossing a continent, in winning a wilderness, and in developing at each area of this progress out of the primitive economic and political conditions of the frontier into the complexity of city life... Thus American development has exhibited not merely advance along a single line, but a return to primitive conditions on a continually advancing frontier line, and a new development for that area.

A.
Americans should not have settled the western territories.
B.

C.
American development banished more primitive cultures.
D.
the settlement of the frontier has defined American history.

Answer 1

D.) The settlement of the frontier has defined American history.

Step-by-step explanation:

In this passage, Frederick Jackson Turner is stating his opinion that settlement of the "Great West" defined American history up until the late 1800s. This was in response to an 1890 census, which stated that every part of the United States had some sort of population. To Turner, this meant that the frontier was officially "closed." These ideas together formed the basis for his most famous work, The Significance of the Frontier in American History. (Study Island)
