It increases the United States workforce, many of which were unskilled labor.

Explanation:

The shift in the late 1800s and early 1900s, immigration to the United States from primarily northern and western Europe to eastern and southern Europe and Asia led to an "increase in the United States workforce, many of which were unskilled laborers."

In the late 1800s and early 1900s, in what was associated with the Gilded Age in the United States, there was an increase in the industrial development of the United States, particularly in the manufacturing and transportation sector.

As a result, there is a need for cheap labor, and the influx of immigrants from eastern and southern Europe and Asia increases the United States workforce, many of which were unskilled laborers.

hello!

according to the passage the most suitable options are two. the first one is "by leading the aef to victory in several key battles" like the battle of saint- mihiel and the battle of cantigny mentioned in the passage you copied here. the second one is "by the aef and allied forces defeat germany" since the passage says that his army destroy the german resistance in the meuse- argonne offensive. and also, "by insisting that the aef operate as an independent force".

hope this
