Which of the following encouraged president arthur to pursue civil service reform?

I think you forgot to give the options along with the question. I am answering the question based on my research and knowledge. "Assassination of President Garfield" is the one that encouraged President Arthur to pursue civil service reform. I hope that this is the answer that has come to your great help.

If i’m not mistaken your answer should be the freemen’s bureau started them. i really hope i could ! good luck
