B. The preamble,The Preamble to the
Constitution mainly serves as an introductory statement that outlines
the reasons the U.S. Constitution was written and the values it
represents.
The main reason the United States government intervened in the Great Railroad Strike of 1877 was because it was leaving thousands of people without transportation, which meant that the US GDP was decreasing in hurting business of all kinds.
Answer:
The Monroe doctrine stated that the U.S. should use military force to prevent any form of intervention from an European power in the western hemisphere.
The Roosevelt corollary was different in that it allowed European powers to intervene as long as the intervention was considered justified, but not to invade.
This difference became clear during the Venezuelan crisis of 1902-1903, when Germany, Britain, and Italy imposed a naval blockade on Venezuela because the Venezuela president refused to pay for the damages suffered by European citizens during the recent civil war.
At first, Theodore Roosevelt allowed the blockade to continue because he believed that it was justified, but when Germany threatened to invade Venezuela, he intervened sending a fleet under Admiral George Dewey.
