Final answer:
In Document A, the rebellion is a class issue because the labor protest aimed to build solidarity across the racial divide based on social class. It is also a race issue because the management responded by dividing the white and black strikers, recognizing the potential threat of class consciousness.
Step-by-step explanation:
In Document A, we can identify the rebellion as a class issue by examining the context of the labor protest in Gastonia, North Carolina. The biracial union that emerged during the late 1920s aimed to build solidarity across the racial divide based on social class rather than race. This demonstrates that the rebellion was driven by the desire for fair wages and improved working conditions, which are key concerns of the working class.
We can identify the rebellion as a race issue by considering the response of the mills' management. They brought in replacement workers and sought to divide the white and black strikers, recognizing the potential threat of class consciousness in a region where black and white workers had been historically played against one another. This division based on race reveals that race was a factor in the rebellion.
