Question: How many days did one of the largest battles in medieval Europe last? Passage:The Polish–Lithuanian–Teutonic War or Great War occurred between 1409 and 1411, pitting the allied Kingdom of Poland and Grand Duchy of Lithuania against the Teutonic Knights. Inspired by the local Samogitian uprising, the war began by Teutonic invasion of Poland in August 1409. As neither side was ready for a full-scale war, Wenceslaus IV of Bohemia brokered a nine-month truce. After the truce expired in June 1410, the military-religious monks were decisively defeated in the Battle of Grunwald (Tannenberg), one of the largest battles in medieval Europe. Most of the Teutonic leadership was killed or taken prisoner. While defeated, the Teutonic Knights withstood the siege on their capital in Marienburg (Malbork) and suffered only minimal territorial losses in the Peace of Thorn (1411). Territorial disputes lasted until the Peace of Melno of 1422. However, the Knights never recovered their former power and the financial burden of war reparations caused internal conflicts and economic decline in their lands. The war shifted the balance of power in Central Europe and marked the rise of the Polish–Lithuanian union as the dominant power in the region.

Question: How old was Robert McAlpine when work on the NMUK site commenced? Passage:In February 1984, Nissan and the UK government signed an agreement to build a car plant in the UK. The following month a greenfield site in Sunderland, Tyne and Wear, was chosen. As an incentive the land was offered to Nissan at agricultural prices; around £1,800 per acre. The North East region of England had recently undergone a period of industrial decline, with the closure of most of the shipyards on the Wear and Tyne, and the closure of many coal mines on the once prosperous Durham coalfield. The high unemployment this caused meant Nissan had a large, eager, manufacturing-skilled workforce to draw upon. The site, once the Sunderland Airfield (formerly RAF Usworth), was close to ports on the Wear and Tyne, within easy driving distance of the international Newcastle Airport, and close to major trunk roads such as the A1 and A19, as well as major ports for the export of vehicles. The established company became known as Nissan Motor Manufacturing (UK) Ltd, or NMUK. A ground breaking ceremony took place in July, and work began on the site in November 1984, by building contractors Sir Robert McAlpine.
