Blacks were kept from exercising their rights in the South after Reconstruction by all of the following methods except
A. Grandfather clauses
B. Jim Crow laws
C. Poll taxes
D. Literacy tests
E. Tort cases
The best answer to this question is Option E, though really, Option A is not a very good answer. It is still not the best answer to this question, though, because it has to do with civil rights. Option E, by contrast, has nothing to do with keeping blacks from voting. Therefore, it is the best answer.
Blacks were kept from voting by laws that were ostensibly race-neutral. These were things like literacy tests and poll taxes that could be used to prevent blacks from voting since so many blacks were poor and/or illiterate. Therefore, Options C and D clearly were used to keep blacks from exercising their right to vote. The problem with this was that many whites were also poor or illiterate. To allow them to vote, grandfather clauses were enacted. Thus, Option A is really about letting white people vote, not about keeping blacks from voting.
Even so, Option E is clearly the right answer. Tort cases are civil lawsuits. These are things that you file when someone has injured you or caused you to lose money. You could file a tort case if someone negligently let a piece of wood fall off their pickup and it caused you to wreck your car. This sort of thing has nothing to do with civil rights at all. Therefore, it is the right answer.
