Answer :
The correct answer to this open question is the following.
Although there are no options attached we can say the following.
One specific example of how farmer movements challenged railroads in the period from 1865 to 1898. was the fact that American farmers protested that railroads had monopolistic practices and offered expensive prices for the transportation of goods and that directly hurt the economy of the farmers and impacted agriculture production. In simpler terms, for farmers, railroads charged elevated and unfair prices for the services they provided and farmers did not have any other alternative to transport their crops.
These high prices severely impacted the economy of farmers that already had some economic struggles due to low income.
