Input: Consider Input: 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.

Input: Consider Input: Question: What city is the team in that faced Arizona in the Las Vegas Bowl? Passage:After going 6–6 in 2006, the Wildcats lost three of their first four games in 2007, including a 29–27 loss at home to New Mexico. In that game, Stoops gained a 15-yard unsportsmanlike conduct penalty for his behavior on the sideline, which led to a New Mexico touchdown. Following a 2007, 21–20 home loss to Stanford, dropping the team to 2–6, local media began speculating as to whether Stoops would be fired. However, subsequent statements by the athletic director and the university's president indicated that Stoops would return for an additional season. At the beginning of the season, many believed this to be the year Stoops and the Wildcats would reach their first college bowl game in a decade; a winning season was considered a must in order for Stoops to remain as Wildcats head coach. Under the direction of Stoops, Arizona scored 70 points in the season opener against the Idaho Vandals, falling just four points short of a school record for points scored in a game. They went on to soundly defeat Toledo, UCLA, Washington, and California, but lost close games to New Mexico and Stanford. They went on to defeat Washington State on the road to secure bowl eligibility at six wins, but lost to Oregon on the road after mounting a dramatic second-half come-from-behind rally, and to Oregon State in Tucson on a last-second field goal. The Wildcats' final game of the regular season was a 31–10 victory on December 6 in Tucson against Arizona State in the annual Territorial Cup rivalry game. With that win and a final regular season record of 7–5, Arizona accepted a bid from to the Las Vegas Bowl to face BYU. It was the Wildcats' first bowl appearance since the 1998 Holiday Bowl. Stoops' reputation in Tucson was mixed; while the Wildcats had a winning record and appeared in and won their first bowl game in ten years, many fans were divided during the season on whether he should be retained as head coach, as they expected Stoops to guide the team to an eight, nine or even ten-win season given the talent level and the offensive and defensive systems employed by the Wildcats (and with the overall talent level in the Pac-10 conference perceived to be not as strong as usual in 2008). While Stoops brought the Wildcat football program to a level of respectability which was lost during the era of John Mackovic, some fans were disappointed the program was not at the elite level of Stoops' former program Oklahoma or of perennial Pac-10 football power USC. However, Stoops was given strong votes of confidence by UA (later UNLV) athletic director Jim Livengood, by university president Dr. Robert Shelton, and by several prominent Arizona football boosters.
