Question: Question: How many months before the buildup to Knightfall did the death of Superman occur? Passage:Within the regular series, the buildup to "Knightfall" begins with a six-issue run in Batman #484-489 (September 1992 - February 1993), in which Batman (at the onset of a personal psychological mid-life crisis) is forced to deal, in rapid succession, with the returning villain Black Mask and his gang (who target Bruce Wayne and Lucius Fox), a crazed killer called Metalhead, and a sharpshooter assassin hired by an imprisoned mobster to murder Commissioner Gordon. Batman begins to feel that he has lost his edge, especially after his failure to capture Black Mask. He finds himself unable to meditate or even focus. As Bruce Wayne, he contacts holistic therapist Shondra Kinsolving for treatment. He also assigns Robin (Tim Drake) to train Jean-Paul Valley in detective work to aid them as an ally, hoping to guide Valley's brainwashing away from making him a villainous threat. Despite the advice of everyone in his life, including Dr. Kinsolving, Bruce refuses to rest and continues to pursue his self-imposed duty despite his worsening condition (although not explicitly noted as a cause, these events take place immediately after the death of Superman, Batman's peer, elsewhere in the DC Universe).

Question: Question: How many soldiers did Britain send to World War I the year Roebuck arrived on the Western Front? Passage:As a boy, Roebuck worked as a trammer and after being sentenced to one month's imprisonment for stealing a watch in 1904, he enlisted in the York and Lancaster Regiment. Over the next seven years, he was stationed in India and Ireland and was promoted to lance corporal, but was demoted back to private in 1910 for "misconduct". He married in 1908 and had two children. Roebuck was discharged into the reserves in 1912 and likely returned to work as a miner prior to becoming a professional footballer in 1913. After Britain's entry into the First World War in August 1914, he was called up by the York and Lancaster Regiment and arrived on the Western Front in September 1914. On 18 October 1914, Roebuck recorded as "presumed dead" after an attack near Beaucamps-Ligny during the Race to the Sea. His death was confirmed by two comrades in January 1915. Roebuck is commemorated on the Ploegsteert Memorial to the Missing.

Question: Question: Which of the planes that American used for their daily service from Los Angeles to Sydney, Auckland and Hong Kong is the largest? Passage:American expanded its service to Asia and the Pacific. It was one of the initial US bidders in February 2010 to serve Tokyo's Haneda Airport, and was awarded rights to serve Haneda from New York JFK. American planned to begin JFK-Haneda service in January 2011, but postponed the service until February 2011 citing low booking demand, ultimately terminating its JFK-Narita service in favor of JFK-Haneda service in June 2012. American later cancelled its JFK-Haneda service in October 2013 due to the service being "quite unprofitable" due to the time constraints at Haneda Airport. American also began service between Los Angeles and Shanghai in 2011 and between Dallas/Fort Worth and Seoul in 2013, and from Dallas/Fort Worth International Airport to both Shanghai and Hong Kong in the summer of 2014, providing the first ever nonstop service between Dallas/Fort Worth and China. In October 2014, American filed a report to the DOT to launch flights from Los Angeles to Tokyo-Haneda in place of Delta's Seattle-Tacoma operating slot, sparking a war that lasted for over eight months. American was originally granted the slot as a back-up to Delta's Seattle-Haneda route if it failed to operate on a daily basis on March 28, 2015 (which would give the operating rights to American), but in June 2015, Delta announced the cancellation of its Seattle-Haneda service, claiming the daily operation was not feasible due to the route not being an economically viable one in the Seattle market due to certain regulatory and market conditions. American launched daily service from Los Angeles to Tokyo-Haneda on February 11, 2016 using their Boeing 787 aircraft. American also added daily service from Los Angeles to Sydney, Auckland and Hong Kong on their flagship Boeing 777-300ER (to Sydney and Hong Kong) and Boeing 787-8 (to Auckland) respectively (the flights to Auckland and Sydney was replaced by Boeing 787-9 aircraft in Fall 2017), returning to Australia and New Zealand for the first time since the 1990s and providing the first ever non-stop service between the Continental U.S. and Australia and New Zealand on American Airlines. American added service from Los Angeles to Beijing on November 5, 2017, and has plans for more expansion in the Asia-Pacific region in the coming years. As of November 2017, American Airlines offers service to eight destinations in Asia and Oceania from its hubs in Los Angeles, Chicago and Dallas-Fort Worth, offering a total of fifteen routes.
