D is the only correct statement.
The correct answer is false.
It is false that according to the Commission on Industrial Relations, more than two-thirds of the country's mining and manufacturing workers lived in more prosperity than they had ever known.
The Commission on Industrial Relations saw its origins in 1912 to revise the laws on labor in the United States. Also known as the Walsh Commission, investigated the labor situation in the United States during the period of 1913 to 1915 and draw its conclusions that were presented one year later. By no means, the Commission stated that more than two-thirds of the country's mining and manufacturing workers lived in more prosperity than they had ever known.
There's no document provided, I'll answer to the best of my knowledge
The abolitionist John Brown attempted to garner attention and do his part to abolish slavery by murdering three individuals who supported slavery, and later tried to host an armed uprising where he would lead slaves to raid a federal army in Harper's Ferry. The attack was unsuccessful, and he was later executed. His actions were radical, and in my opinion very misguided and would only lead to more violence.
That is my take on it, though I recommend you get your own opinion because that is a very opinionated topic.
