Input: Consider Input: Question: What is the current population of the state from which The Army of Georgia returned in mid-May? Passage:On May 10, United States President Andrew Johnson had declared that the rebellion and armed resistance was virtually at an end, and had made plans with government authorities for a formal review to honor the troops. One of his side goals was to change the mood of the capital, which was still in mourning following the assassination of United States President Abraham Lincoln a month before at Ford's Theater. Three of the leading Federal armies were close enough to participate in the procession. The Army of the Tennessee arrived via train. The Army of Georgia, also under the command of William T. Sherman, had just completed its Carolinas Campaign and had accepted the surrender of the largest remaining Confederate army, that of Joseph E. Johnston. It arrived from North Carolina in mid-May and camped around the capital city in various locations, across the Potomac River from the Army of the Potomac, fresh off its victories over Robert E. Lee in Virginia. It had arrived in Washington on May 12. Officers in the three armies who had not seen each other for some time (in some cases since before the war) communed and renewed acquaintances, while at times, the common infantrymen engaged in verbal sparring (and sometimes fisticuffs) in the town's taverns and bars over which army was superior. Sherman, concerned that his Westerners would not present as polished an image as the eastern army, drilled his forces and insisted that uniforms be cleaned, buttons and brass shined, and that bayonets glistened.

Input: Consider Input: Question: How old was Derow's teacher and lasting influence at Oxford when Derow graduated from Oxford? Passage:Born in Newport, Rhode Island, Derow obtained his secondary education at The Roxbury Latin School in West Roxbury, Massachusetts. After an A.B. degree at Amherst (with Peter K. Marshall), he read for Greats as a second B.A. degree at Oxford in 1965–1967, achieving a First. At Oxford he was taught by, among others, W. G. (George) Forrest, who was a lasting influence. He completed a Ph.D. at Princeton on 'Rome and the Greek world from the earliest contacts to the end of the first Illyrian war', for which Professor J. V. A. Fine was his Advisor; in the preface to that work, he acknowledges the additional inspiration he had drawn from T. J. Luce and the historian and epigrapher C. Bradford Welles. After a spell of teaching at the University of Toronto, he returned to succeed Forrest at Wadham in 1977 when the latter was elected to the Wykeham Professorship of Ancient History at New College. In 2002–2005 Derow was also Director of Graduate Studies in ancient history for the Oxford Faculty of Classics.

Input: Consider Input: Question: How many people can be seated at the venue where Fisher competed in the EA Sports 500? Passage:On February 12, 2004, it was announced that Fisher had switched from Dreyer & Reinbold Racing to Kelley Racing; the team expressed its hope of taking part for the majority of the 2004 season but Fisher did not contest the season-opening Toyota Indy 300 due to a lack of sponsorship. Two months later, Fisher entered the Indianapolis 500 in Kelley's No. 39 Dallara Toyota Indy V8 entry after they received sponsorship for the event. She qualified in 19th and finished the rain-shortened race in 21st. Afterward she sought another team for which to drive. Later that year, Fisher made her stock car racing debut, entering a NASCAR West Series (now NASCAR K&N Pro Series West) race in the No. 20 Bill McAnally Racing car at Phoenix after Richard Childress Racing (RCR) owner Richard Childress asked Bill McAnally if she could fill in for Kerry Earnhardt, who was competing in the EA Sports 500 at Talladega Superspeedway. Fisher qualified in 14th and finished in 21st place due to a battery failure after 104 laps.
