Input: Consider Input: Question: Where was the man born who had an accident on lap 70 of the race? Passage:Ten laps into the race, Michael Waltrip passed pole-sitter Jeff Gordon for the lead. On Lap 19, the caution flag was thrown after a multi-car accident. Waltrip continued leading until Lap 55, in which Dale Earnhardt Incorporated teammate Dale Earnhardt, Jr. After Bobby Hamilton, Jr. had an accident on Lap 70, Earnhardt led the race into pit road, but was pushed out by Gordon and Brian Vickers, and fell to fifteenth, giving Mike Wallace the lead entering Lap 74. Shepherd pitted on the following lap, and Morgan Shepherd took the lead. However, Shepherd would later pit, as Gordon regained the lead. Waltrip then retook the lead from Gordon on Lap 86, though Gordon then took the lead again 13 laps later. Ten laps later, Gordon pitted, and Waltrip was given the lead. On the ensuing lap, Earnhardt took the lead, though he later pitted, and Jimmy Spencer gained the lead. On Lap 113, Spencer lost the lead to Gordon when he pitted, who led the pit stops on Lap 139. Dave Blaney stayed out, and took the lead, though Ryan Newman gained first-place when Blaney went to pit road. Newman pitted on Lap 143, giving Tony Stewart the lead. With ten laps left in the race, Hendrick Motorsports teammates Jeff Gordon and Jimmie Johnson followed in third and fourth, respectively, behind Tony Stewart and Dale Earnhardt, Jr. Johnson then pushed Gordon past Stewart and Earnhardt, and Gordon subsequently won, his fourth of the season and second consecutive.

Input: Consider Input: Question: How old was the person who escaped to Africa when Cleopatra ascended to the throne? Passage:Caesar crossed the Rubicon accompanied by the XIII Legion to take power from the senate in the same way that Sulla had done in the past. Formally declared an enemy of the state, Caesar pursued the Senatorial party, now led by Pompey, who abandoned the city to raise arms in Greece. Cato was sent to Sicily to secure control of the grain supply. After securing control of Italy, Caesar sent the praetor Curio with four legions to Sicily. Cato's garrison was insufficient to withstand a force of this magnitude, he abandoned the island and went to Greece to join Pompey. After first reducing Caesar's army at the siege battle of Dyrrhachium, where Cato commanded the port, the army led by Pompey was ultimately defeated by Caesar in the Battle of Pharsalus (Cato wasn't present during the battle, Pompey had left him in command of Dyrrhachium). Cato and Metellus Scipio, however, did not concede defeat and escaped to the province of Africa with fifteen cohorts to continue resistance from Utica. Caesar pursued Cato and Metellus Scipio after installing the queen Cleopatra VII on the throne of Egypt, and in February 46 BC the outnumbered Caesarian legions defeated the army led by Metellus Scipio at the Battle of Thapsus. Acting against his usual strategy of clemency, Caesar did not accept surrender of Scipio's troops, but had them all slaughtered.

Input: Consider Input: Question: In what year was the person who gave additional lessons to Sheridan in Dublin born? Passage:Sheridan had her early vocal training while at school at the Dominican Convent in Eccles Street, Dublin, with additional lessons from Vincent O'Brien. In 1908, she won a gold medal at the Feis Ceoil. From 1909 to 1911 she studied at the Royal Academy of Music in London, during which time she was introduced to the Italian inventor Guglielmo Marconi, who was instrumental in arranging further studies for her in opera in Rome. With Marconi's help she auditioned in 1916 for Alfredo Martino, a prominent singing teacher attached to the Teatro Costanzi, and she made her début there in January 1918 in Puccini's La Bohème. In July 1919 she appeared at the Royal Opera House (Covent Garden) in the title role in Iris by Pietro Mascagni. Sheridan returned to Italy, where her career continued to grow, with performances at the Teatro Dal Verme in Milan and at the Teatro San Carlo in Naples, primarily in Puccini roles. In 1922 she first sang at La Scala, Milan, in La Wally by Catalani under the direction of Toscanini. For the next few years she would sing at La Scala with great success. Perhaps her greatest role was Madama Butterfly, which she sang extensively in Italy and at Covent Garden. When she played the part of Madama Butterfly, Puccini was said to be spellbound.
