Question: How long had the organization that bought the original site existed when the university was moved? Passage:Consequently, in 1870, it moved to a (then greenfield) site on Gilmorehill in the West End of the city, around three miles (5km) west of its previous location, enclosed by a large meander of the River Kelvin. The original site on the High Street was sold to the City of Glasgow Union Railway and replaced by the College goods yard. The new-build campus was designed by Sir George Gilbert Scott in the Gothic revival style. The largest of these buildings echoed, on a far grander scale, the original High Street campus's twin-quadrangle layout, and may have been inspired by Ypres' late medieval cloth hall; Gilmorehill in turn inspired the design of the Clocktower complex of buildings for the new University of Otago in New Zealand. In 1879, Gilbert Scott's son, Oldrid, completed this original vision by building an open undercroft forming two quadrangles, above which is his grand Bute Hall (used for examinations and graduation ceremonies), named after its donor, John Crichton-Stuart, 3rd Marquess of Bute. Oldrid also later added a spire to the building's signature gothic bell tower in 1887, bringing it to a total height of some . The local Bishopbriggs blond sandstone cladding and Gothic design of the building's exterior belie the modernity of its Victorian construction; Scott's building is structured upon what was then a cutting-edge riveted iron frame construction, supporting a lightweight wooden-beam roof. The building also forms the second-largest example of Gothic revival architecture in Britain, after the Palace of Westminster. An illustration of the Main Building currently features on the reverse side of the current series of 100 notes issued by the Clydesdale Bank.

Question: How old was the person who broke King's record in 1925? Passage:In April 1914 he joined Arsenal for a 1,000 fee, returning to League football. Arsenal had just missed out on promotion on goal average to the First Division, and in 191415 King spearheaded their attack, scoring 26 goals in the League and another three in the FA Cup. These included the first hat trick scored at their new Highbury stadium (against Grimsby Town on 14 November 1914), and two four-goal hauls against Wolverhampton Wanderers and Nottingham Forest. King's 29 goals that season were an all-time club record at the time, remaining so until Jimmy Brain broke it in 192526. However, Arsenal's defence let them down and they only finished fifth, outside of the promotion places; eventually, they were re-elected back to the First Division when football resumed after the end of the First World War.
