Final answer:
The U.S. Supreme Court ruled on several voting rights issues in Farmer v. Brenman, including the illegality of literacy tests and restrictions on voting based on property ownership or taxation. They also ruled against lengthy residence requirements and rural voter representation. The case was vital in promoting equal voting rights.
Step-by-step explanation:
In Farmer v. Brenman, the U.S. Supreme Court ruled on several issues related to voting rights and disenfranchisement. They declared literacy tests illegal in areas where schools had been segregated and struck down laws restricting the vote to property-owners or tax-payers. The court also ruled that lengthy residence rules for voting were unconstitutional. Additionally, the court ruled in the Baker v. Carr decision that states could not give rural voters a disproportionate sway in state legislatures. The ruling in Farmer v. Brenman played a significant role in promoting equal voting rights and eliminating discriminatory practices.
