Wealthy businessmen and rich tenant farmers.
Answer:
The correct answer is D) The Jim Crow laws.
Explanation:
The question refers to the case of Homer Plessy, in 1892, who bought a first-class ticket from New Orleans. After he took a seat in a compartment for white people he was invited to move to the "colored" cars. After he refused, he was arrested and thrown out of the train.
It caused further tension because of the uncertainty of slavery. The northern states feared that slavery would spread to these new territories, therefore causing tensions to rise between the country.
The North and the South disagreed heavily on the topic of slavery. The North wanted it destroyed, but the South wanted it to spread. As time passed the tension built. One of the tipping points was when John Brown tried to start a revolution by stealing guns for the slaves from a weapons depot in the South. He was caught before anyone was hurt and sentenced to hang. The North call him a martyr, which enraged the South, since he had been planning to hurt and kill them.
