[Q]: Question: Which direction does the river that encloses the university flow in? Passage:Consequently, in 1870, it moved to a (then greenfield) site on Gilmorehill in the West End of the city, around three miles (5 km) 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.

[Q]: Question: What were the main groups involved in the event that resulted in the sacking of Constantinople in 1204? Passage:Papal calls for renewed holy war at the end of the twelfth century inspired not only the disastrous Fourth Crusade that sacked Constantinople in 1204, but also a series of simultaneous "Northern Crusades" that are less fully covered in English-language popular history, but which were more successful in the long run. Before the crusades, the region of Livonia was a mixed outpost, a pagan society where merchants from the Hanseatic League encountered merchants of Novgorod, and where Germanic, Scandinavian, and Russian trade, culture, and cults all mingled. The specific ethnic groups that intermingled and traded with the Germans, Danish, Swedish, and Russians here included the Wends, who were merchants from Lübeck, the Estonians, the Karelians, the Kuronians, the Lettgallians, the Semgallians (sometimes known as the Letts), the Livonians and the Lithuanians. The Western merchants would trade silver, textiles, and other luxury goods for furs, beeswax, honey, leather, dried fish, and amber. Livonia had been an especially promising location in terms of resources, and Arnold of Lübeck, in his Chronicle of the Slavs wrote that the land was "abundant in many riches" and was "fertile in fields, plentiful in pastures, irrigated by rivers", and "also sufficiently rich in fish and forested with trees".
