Example Input: Question: Who was the first to put forth the Voting Rights Act of 1965? Passage:In the United States, the Fifteenth Amendment to the United States Constitution, ratified in 1870 during the Reconstruction era, provided 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." This amendment aimed to guarantee the right to vote to African Americans, many of whom had been enslaved in the South prior to the end (1865) of the American Civil War and the 1864-1865 abolition of slavery. Despite the amendment, however, blacks were disfranchised in the former Confederate states after 1877; Southern officials ignored the amendment and blocked black citizens from voting through a variety of devices, including poll taxes, literacy tests, and grandfather clauses; violence and terrorism were used to intimidate some would-be voters. Southern blacks did not effectively receive the right to vote until the Voting Rights Act of 1965.
 Links: a. Disenfranchisement after the Reconstruction Era b. Voting Rights Act of 1965 c. Reconstruction era d. African Americans
Example Output: b

Example Input: Question: Do more people live in Fauntleroy's birth place than the town where he died? Passage:Archibald Magill Fauntleroy (b. in Warrenton, Virginia, 8 July 1837; d. in Staunton, Virginia, 19 June 1886) was a physician. He graduated in medicine at the University of Pennsylvania in 1856, and in 1857 entered the United States Army as assistant surgeon; but, upon the start of the Civil War, he and his brother, a lieutenant in the navy, resigned at the same time with their father, Thomas T. Fauntleroy. He became a surgeon in the Confederate army, and was president of the board for the admission of surgeons, and chief officer on the medical staff of Gen. Joseph E. Johnston, and served with him until the battle of Seven Pines. He was then ordered to build and organize the hospitals at Danville, Virginia, and afterward had charge of the military hospital at Staunton, Virginia, until the war ended. He remained and practised at Staunton after the war, and was for several years superintendent of the lunatic asylum at that place. His contributions to medical literature include papers on potassium bromide, chloral hydrate, the use of chloroform in obstetrical practice, and a “Report upon Advance in Therapeutics,” which was printed in the Transactions of the Virginia Medical Society.
