[Q]: Question: Which Nigerian region that saw their teams' promotion to the Premier League has the largest population? Passage:The 2018 Nigeria Women Premier League began on April 7 in a game featuring defending champions Nasarawa Amazons from Nasarawa State and FC Robo of Lagos State. The date was decided following a congress held in Ikeja on March 3. Prior to the game, a maiden super cup named the NWFL Champions Shield match was played between Aiteo Cup winners, Rivers Angels and Nasarawa Amazons to officially open the new season. At the end of the 2017 season, Sure Babes of Ilorin, Jokodolu Babes of Ogbomosho and Taraba Queens of Taraba State were promoted to compete in the elite division pending registration procedures, while Saadatu Amazons of Minna and Heartland Queens of Owerri were relegated to the pro league. In May 2018, the league went on a mid-season break due to the 2018 FIFA World Cup, this was further elongated after an emerging NFF leadership crisis. In August 2018, it was announced that the remaining games of the league will commence September 12.

[Q]: Question: How many years were there between the end of the British Burma Campaign and the start of the Battle of Na San? Passage:The First Indochina War had raged, as guerrilla warfare, since 19 December 1946. From 1949, it evolved into conventional warfare, due largely to aid from the communists of the People's Republic of China ("PRC") to the north. Subsequently, the French strategy of occupying small, poorly defended outposts throughout Indochina, particularly along the Vietnamese-Chinese border, started failing. Thanks to the terrain, popular support for August Revolution and support for decolonization from bordering China and the U.S.S.R., the Viet Minh had succeeded in turning a "clandestine guerrilla movement into a powerful conventional army", following asymmetric warfare theory laid by Mao Tse Tung, something which previously had never been encountered by the western colonial powers. In October 1952, fighting around the Red River Delta spread into the Thai Highlands, resulting in the Battle of Nà Sản, at which the Viet Minh were defeated. The French used the lessons learned at Nà Sản – strong ground bases, versatile air support, and a model based on the British Burma Campaign – as the basis for their new strategy. The Viet Minh, however, remained unbeatable in the highland regions of Vietnam, and the French "could not offset the fundamental disadvantages of a roadbound army facing a hill and forest army in a country which had few roads but a great many hills and forests".

[Q]: Question: What age was the Mets' manager when he switched Yoshii for Orel Hershiser? Passage:The game began shortly after 4 p.m. with Greg Maddux pitching for Atlanta and Masato Yoshii starting for the Mets. The Mets took an early 2–0 lead in the bottom of the first inning as John Olerud hit his second home run in as many days with Rickey Henderson on first. The lead lasted into the fourth inning, when Atlanta struck back with consecutive doubles by Bret Boone and Chipper Jones, eventually knotting the score at 2–2 when Brian Jordan singled home Jones. Mets Manager Bobby Valentine was immediately prompted to remove Yoshii from the game in favor of Orel Hershiser, which began a run on pitching changes that resulted in the Mets emptying their bullpen by game's end, relying on starter Kenny Rogers and rookie Octavio Dotel for key innings, and might have gone to Game 4's starter Rick Reed had the game progressed past the fifteenth inning. In all, the Mets used a postseason record nine pitchers in this game.
