Example Input: Question: Which of the two cities where McCartney was scheduled to headline has more residents? Passage:On 15 February 2016, McCartney announced two initial festival dates in Europe for the upcoming summer. These two headlining performances at Pinkpop Festival in Landgraaf, Netherlands and Rock Werchter in Werchter, Belgium were revealed before the initial revelation of the "One on One" tour. These tours would feature mostly similar elements of the "One on One" performances yet with a condensed set list to allot for festival curfew limits and less stage elements given restrictions. In the wake of the passing of notable Beatles and McCartney producer George Martin, McCartney announced the initial "One on One" dates for North America and Europe. In North America, McCartney's visit to Fresno, California would mark his first performance in the city, and his performances in North Little Rock and Sioux Falls would be his first performances in the states of Arkansas and South Dakota respectively. Elsewhere in North America, McCartney would perform in Portland after an eleven-year absence following his 2005 'US' tour. The two shows in Vancouver would follow his previous performance in the city at the BC Place stadium in 2012, yet this tour would feature two shows in the neighboring Rogers Arena after the pyrotechnics during his concert at BC Place accidentally damaged the stadium's new roof. McCartney's Seattle show would mark his shortest absence from any North American city on the tour announced currently, as he performed at the city's Safeco Field during the inaugural year of the 'Out There' tour. McCartney announced a performance on 16 March in Minneapolis at the Target Center. This show would take place on 4 May 2016, less than two years after McCartney's last performance in the city at the adjacent baseball stadium sharing a corporate sponsor with the arena, Target Field. Due to high demand of tickets a second show in Minneapolis was announced the next day and would take place on 5 May.

Example Input: Question: What date did the division land on Utah Beach? Passage:The division arrived in Liverpool on April 17 and began training in amphibious operations. After training in the United Kingdom from 17 April 1944, the 79th Infantry Division landed on Utah Beach, Normandy, 12–14 June and entered combat 19 June 1944, with an attack on the high ground west and northwest of Valognes and high ground south of Cherbourg. The division took Fort du Roule after a heavy engagement and entered Cherbourg, 25 June. It was around this time that Corporal John D. Kelly and First Lieutenant Carlos C. Ogden, both of the 314th Infantry Regiment, were awarded the Medal of Honor. It held a defensive line at the Ollonde River until 2 July 1944 and then returned to the offensive, taking La Haye du Puits in house-to-house fighting, 8 July. On 26 July, the 79th attacked across the Ay River, took Lessay, crossed the Sarthe River and entered Le Mans, 8 August, meeting only light resistance. The advance continued across the Seine, 19 August. Heavy German counterattacks were repelled, 22–27 August, and the division reached the Therain River, 31 August. Moving swiftly to the Franco-Belgian frontier near St. Amand (east of Lille), the division was then moved to XV Corps in eastern France, where it encountered heavy resistance in taking Charmes in street fighting, 12 September. The 79th cut across the Moselle and Meurthe Rivers, 13–23 September, cleared the Forêt de Parroy in a severe engagement, 28 September–9 October, and attacked to gain high ground east of Emberménil, 14–23 October, when it was relieved, 24 October.

Example Input: Question: How many people can Stamford Bridge hold at max capacity? Passage:The quarter-final draw also determined the teams' routes to the final, with Barcelona facing the prospect of meeting either Chelsea or Liverpool in the semi-finals. After a 3–1 win at Anfield, Chelsea qualified for the semi-finals with a 4–4 draw at Stamford Bridge. The semi-final first leg was played at the Camp Nou; although Barcelona enjoyed the majority of the possession, Chelsea's defence was resolute and they became the first side to keep a clean sheet in Barcelona in this season's competition, coming away with a goalless draw. Barcelona needed to avoid defeat to reach the final, but they found themselves a goal down within 10 minutes; after they failed to clear Frank Lampard's pass into the penalty area, Michael Essien fired a left-footed volley past Víctor Valdés into the roof of the net. The rest of the match continued much the same as the first leg, with Barcelona retaining most of the possession. Despite this, they found themselves guilty of several fouls, while Chelsea made four unsuccessful penalty appeals during the match. Meanwhile, Dani Alves received his third yellow card of the knockout phase, ruling him out of Barcelona's next match, and Eric Abidal was given a straight red card for a foul on Nicolas Anelka as the French forward was through on goal. However, television replays after the incident showed that there was little contact between Abidal and Anelka. Norwegian referee Tom Henning Øvrebø allowed a minimum of four minutes of injury time at the end of the second half; in the third of those four minutes – just when it looked like Chelsea were about to secure a repeat of the 2008 final – Messi played the ball across the edge of the penalty area to Andrés Iniesta, who shot just past Petr Čech's outstretched hand for the away goal that would send Barcelona to the final.
