"Sir: . . . Doubtless you have learned of the great exodus of our people to the north and west from this and other states. I wish to say that we are forced to go when one thinks of a grown man wages is only fifty to seventy cents per day for all grades of work. He is compelled to go where there is better wages and sociable conditions, believe me. When I say that [at] many places here in this state the only thing the black man gets is a peck of meal and from three to four lbs. of bacon per week, and he is treated as a slave."-From Emmett J. Scott, ed. "Letters of Negro Migrants of 1916-1918," Journal of Negro History 4, 1919The excerpt is best understood as a response to which of the following historical developments?

These floors, it must be noted, were in most cases damp and soggy, in dark, ill-ventilated rooms, and the employees in utter ignorance of cleanliness or danger to health, expectorated at will upon them. In a word, we saw meat shoveled from filthy wooden floors, piled on tables rarely washed, pushed from room to room in rotten box carts, in all of which processes it was in the way of gathering dirt, splinters, floor filth, and the expectoration of tuberculosis and other diseased workers."-Source: "The Neill-Reynolds Report," 1906Which of the following developments contributed most directly to the conditions described in the excerpt?

Men suffered from this. There were lawyers enough; many of our ablest men were lawyers. Why didn't some of them invent legislative implements to help the people govern themselves? Why had we no tool makers for democracy?"-Source: William Simon U'Ren, in American Magazine, Volume 65, 1908Which of the following historical political parties would be most likely to oppose the views expressed in the excerpt?
