The correct answer for the question that is being presented above is this one: "Rebates to large companies!" The railroad practice did reformers call on governments to legislate in the late 1800s, with minimal success is that Rebates to large companies!
A secondary source could be someone that maybe discovered the body or is doing evaluations to see why or how he died, like a doctor for instance it would be a secondary source because............the doctor was not there and he did not watch so....and if he wrote about it then that would be a secondary source! :) <3 hope this helps!
