Example Input: Question: How old was Adrian "King" Cole the year that headquarters RAAF Station Richmond was formed as a separate entity? Passage:A military flying school was set up at the site of the present-day RAAF base on 28 August 1916, when the area was known as Ham Common. RAAF Station Richmond was established on 30 June 1925 as the fledgling service's first air base outside Victoria. Its initial flying unit was No. 3 (Army Cooperation) Squadron, operating Airco DH.9 light bombers and Royal Aircraft Factory S.E.5 fighters, and for the next decade the commanding officer of No. 3 Squadron was also in charge of the base. Among these were Squadron Leaders Frank Lukis (1925–30), Harry Cobby (1930–31), and Bill Bostock (1931–33). Headquarters RAAF Station Richmond was formed as a separate entity on 20 April 1936, under the command of Group Captain Adrian "King" Cole. Other units, including No. 22 Squadron flying Hawker Demons, and No. 2 Aircraft Depot, had been established in the preceding months. No. 4 (General Reconnaissance) Squadron was formed in May 1937, followed by No. 6 (General Reconnaissance) Squadron in March 1939. Two Fleet Cooperation units were also established, No. 5 Squadron in April 1936 and No. 9 Squadron in January 1939. No. 23 (General Purpose) Squadron formed in February 1939. As well as an Air Force base, in its pre-war days Richmond was used as a supplementary airport for Sydney; various aviation pioneers employed it in the 1930s, including Charles Kingsford Smith and Jean Batten.

Example Input: Question: How long has Nakayama been president of Sega when he was looking for a flagship series to compete with Mario? Passage:In 1990, Sega president Hayao Nakayama sought a flagship series to compete with Nintendo's Mario franchise along with a character to serve as a company mascot. Several character designs were submitted as part of a contest. Among the designs was an egg-shaped man wearing pajamas who resembled Theodore Roosevelt, drawn by Naoto Ohshima. According to Ohshima, the resemblance to Roosevelt was unintentional, saying he was influenced by a variety of characters. Retrospective sources have indicated Ohshima based the character on Humpty Dumpty and Mario. The Roosevelt lookalike did not win the contest; rather, another Ohshima character, a hedgehog named Mr. Needlemouse—later renamed Sonic—prevailed. As development of the Sega Genesis game Sonic the Hedgehog progressed, however, programmer Yuji Naka and the rest of Sonic Team thought the rejected design was excellent and deserved inclusion in the game. Since the character could not be the protagonist, the team retooled him into the game's main antagonist.

Example Output: b

Example Input: Question: How many albums total did the Beatles record in Hamburg? Passage:Ain't She Sweet was an American album featuring four tracks recorded in Hamburg in 1961 by The Beatles featuring Tony Sheridan (except for the title song with vocal by John Lennon) and cover versions of Beatles and British Invasion-era songs recorded by the Swallows. As Atlantic Records only had rights to four Sheridan/Beatle recordings recorded by Polydor Records, they filled the rest of the album with Beatle and British Invasion cover songs. When this material was released by Atco Records, there were mono (catalogue number 33-169) and stereo (SD 33-169) editions. Atco also added additional drum overdubs to the four Sheridan cuts on top of the original drum tracks. American drummer Bernard Purdie claims to have performed overdubs of unspecified Beatles records, which would most likely have been for Ain't She Sweet, but this has never been officially confirmed.
