...Charged very high prices to move farm products to market
The farmers felt the railroads had monopoly power over them. The farmers essentially had no choice but to send their crops to market on trains. There was not much, if any, competition on most short-line tracks that went through farm areas. Therefore, most farmers had to simply accept whatever price railroads charged to transport crops.

Assassination of President Garfield
Explanation;
President Garfield was shot by Charles J. Guiteau at 9:30 am, in Washington, D.C. less than four months into Garfield's term as the 20th President of the United States. Garfield died eleven weeks later on September 19, 1881. His Vice President, Chester A. Arthur, succeeded Garfield as President.
One factor that encouraged president Arthur to pursue the civil service reform was the fact that President Garfield was shot by a crazed office seeker who thought he was owed a government job due to his support for Garfield in the election.
The assassination of James A. Garfield made it possible for the new president and longtime political spoilsman, Chester Arthur, to combat the patronage system's excesses.
