I would say the answer is B. the end of the Cold War
The putting out system was a precursor to the factories of the industrial revolution. It was an intermediate step that came between the system in which everything was made at home and the system in which everything was made in factories.
What come to mind for me is the Cold War. America was fighting for equal rights in eastern Europe and other places under Soviet/Communist infulence, and yet there were not equal rights for every one in America, especially for African-Americans in the south.
