The 15th Amendment to the Constitution, ratified in 1870, guaranteed that "the
right of citizens of the United States to vote shall not be denied or abridged by the
United States or by any State on account of race, color, or previous condition of
servitude." But southern whites found ways to undermine the amendment and
to disenfranchise African Americans. Which of the following is an example of disenfranchisement?
A- literacy test
B- sales tax
C- sharecropping
