As described in NewsRepulic, During the Guided age, as defined by author Mark Twain, during the 1870's in big cities, like Boston, Chicago, New York, Cleveland, corruption was prevalent. The new immigrants, who were mainly looked upon as the least employable, the bottom of the social status, and of little value. They were someone who is new to the country, lacking in language skills, and someone who has come here to take your job. So, for them to assimilate, to survive, many immigrants were forced to join together to provide support the local political bosses. In exchange for their loyalty and votes, the new immigrants were provided, a chance for jobs, housing, help in naturalization, business licenses, assistance in the courts and a voice in the community.
I think it's A because slavery wasn't abolished in Washington DC until 1862.
