Problem: From the league's inception through ArenaBowl XVIII, the championship game was played at the home of the highest-seeded remaining team. The AFL then switched to a neutral-site championship, with ArenaBowls XIX and XX in Las Vegas. New Orleans Arena, home of the New Orleans VooDoo, served as the site of ArenaBowl XXI on July 29, 2007. This was the first professional sports championship to be staged in the city since Hurricane Katrina struck in August 2005. The San Jose SaberCats earned their third championship in six years by defeating the Columbus Destroyers 55–33. ArenaBowl XXI in New Orleans was deemed a success, and the city was chosen to host ArenaBowl XXII, in which the Philadelphia Soul defeated the defending champion San Jose Sabercats. In 2010, the location returned to being decided by which of the two participating teams was seeded higher. In ArenaBowl XXIII, the Spokane Shock defeated the Tampa Bay Storm at their home arena, Spokane Arena, in Spokane, Washington. In ArenaBowl XXIV, the Jacksonville Sharks, coming off of a victory in their conference final game four nights earlier, traveled to US Airways Center in Phoenix and defeated the Arizona Rattlers 73–70. ArenaBowl XXV returned to a neutral site and was once again played in New Orleans, where the Rattlers returned and defeated the Philadelphia Soul. Since 2014 the ArenaBowl has been played at the higher-seeded team.
What arena was ArenaBowl XXI played in?
The answer is the following: New Orleans Arena

Problem: On April 2, 1958, President Eisenhower reacted to the Soviet space lead in launching the first satellite, by recommending to the US Congress that a civilian agency be established to direct nonmilitary space activities. Congress, led by Senate Majority Leader Lyndon B. Johnson, responded by passing the National Aeronautics and Space Act, which Eisenhower signed into law on July 29, 1958. This law turned the National Advisory Committee on Aeronautics into the National Aeronautics and Space Administration (NASA). It also created a Civilian-Military Liaison Committee, chaired by the President, responsible for coordinating the nation's civilian and military space programs.
The National Aeronautics and Space Act was established in what year?
The answer is the following: 1958

Problem: The war had removed Bermuda's primary trading partners, the American colonies, from the empire, and dealt a harsh blow to Bermuda's merchant shipping trade. This also suffered due to the deforestation of Bermuda, as well as the advent of metal ships and steam propulsion, for which it did not have raw materials. During the course of the following War of 1812, the primary market for Bermuda's salt disappeared as the Americans developed their own sources. Control of the Turks had passed to the Bahamas in 1819.
Why didn't Bermuda produce metal ships?
The answer is the following: it did not have raw materials

Problem: The early Qing military was rooted in the Eight Banners first developed by Nurhaci to organize Jurchen society beyond petty clan affiliations. There were eight banners in all, differentiated by color. The yellow, bordered yellow, and white banners were known as the "Upper Three Banners" and were under the direct command of the emperor. Only Manchus belonging to the Upper Three Banners, and selected Han Chinese who had passed the highest level of martial exams could serve as the emperor's personal bodyguards. The remaining Banners were known as the "Lower Five Banners." They were commanded by hereditary Manchu princes descended from Nurhachi's immediate family, known informally as the "Iron cap princes". Together they formed the ruling council of the Manchu nation as well as high command of the army. Nurhachi's son Hong Taiji expanded the system to include mirrored Mongol and Han Banners. After capturing Beijing in 1644, the relatively small Banner armies were further augmented by the Green Standard Army, made up of those Ming troops who had surrendered to the Qing, which eventually outnumbered Banner troops three to one. They maintained their Ming era organization and were led by a mix of Banner and Green Standard officers.[citation needed]
What were the banners called that were under direct leadership of the emperor?
The answer is the following:
Upper Three Banners
