The correct answer is C) establishment of the Freedmen's Bureau.
The acts by Congress that were intended to prevent this repressive social and political order were the establishment of the Freedmen's Bureau.
In a time of ecom¿nomic problems and political instability, the Freedmen's Bureau was a real help for former black slaves and poor white people that lived in the south and practically had nothing after the conclusion of the American Civil War.
The US Congress approved the establishment of the Freedmen's Bureau in 1865 to assist these people with medical attention, food, shelter, and education. Unfortunately, there was not enough money to accomplish these, besides the political "climate" in the racist's southern states never accepted this Freedmen's Bureau.
Germany declared war on France. Of course, Belgians refused to let them through, so the Germans decided to enter by force and invaded Belgium on Aug. 4, 1914. By doing so, they violated the Treaty of London, which is why Great Britain, that was bound to guard the neutrality of Belgium, entered the war.
Due to the technological improvements of the industrial revolution, women were hired as the workforce for numerous industries, particularly in the textile industry.
It was a win to win relationship for both, business owners and female employees, as business owners saw women as a cheaper source of labor in comparison to men. On the other hand, women saw the wages that the industries paid as more attractive than doing housework. Additionally, due to their relatively smaller size in comparison to men, women could also access places within machinery that men couldn't. This was an advantage when it came to maintenance tasks.
