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: Were the Vuippens and Holy Romans allied? Passage:Gümmenen Castle, of which nothing remains, was built by either the Counts of Burgundy or the Dukes of Zähringen as part of the defenses along the Saane, along with Laupen Castle and Grasburg Castle. The castle was built to defend a bridge over the river. By 1391, a village (villa inferiori Dicti castri) had developed around the bridge. In 1259, Peter of Savoy made Gümmenen into an imperial fief and imperial castellans took over the castle and village. In 1282–83 King Rudolph I of Germany forced the Savoy castellan out and granted it to a Habsburg knight, Ulrich II of Maggenberg as a fief. Ulrich's heirs sold the castle, ferry and ford to Fribourg in 1319. Fribourg then granted the lands to the knights of Vuippens, who lost it back to either the Holy Roman Empire or Fribourg in 1325. The castle and village were besieged and destroyed in 1333 during Bern and Fribourg's first war over the Sense and Saane valleys, the Gümmenenkrieg. The peace treaty brokered in 1333 by Queen Agnes returned Gümmenen to Fribourg.
