<u>Explanation:

African Americans are really an ethnicity of Americans of full or partial roots at any of Africa's black racial groups. In particular, the sentence refers to the descendants of slaves from the U.S.
During the years of the sub-Reconstruction era the number of factory jobs in southern cities has only shrunk to a small proportion. Yet comparatively few black Americans purchased their own land in the South, most of the poor landowners being heavily indebted to white property owners.
The predominantly urban population in the north of Africa was not much different. European refugees were given the jobs they desired. A number of African Americans moved to the west in hope of change.
The correct answer here is the public opinion.
All of the methods mentioned here are ways the politicians may test and see the public opinion.

Direct contact with the population is also a method by which the politicians can learn what troubles the said population.
