Example Input: Question: What album was the song "Ignorance" released from? Passage:The Honda Civic tour was the biggest production the band had had so far. The stage was constructed of 3 ramps up to a platform behind the drum set, and 6 large video screens behind that. The show began with a large black curtain concealing the stage while the band played an instrumental intro, with spotlights revealing the silhouettes of the band. As the intro ended, they begin playing "Ignorance" as the curtain simultaneously dropped, the video screens flashing the band's logo during the intro, as the intro progressed the video screen changed to images of light bulbs (similar to the song's music video) during the intro, light bulbs also swung down from the top of the stage, continuing to swing throughout the song. The band then played "Feeling Sorry" as the video screens each showed a live feed of each member of the band performing during the choruses, at the end of the bridge the band would stop playing and Hayley would greet the crowd and welcome them to the tour. After playing "That's What You Get" and "Emergency" the band played "Playing God" as the video screens showed images of picture frames, the same picture frames on the back of Brand New Eyes and the song's single cover. After that they played Careful, as images of the Brand New Eyes butterfly flashed during the chorus, they then continued with their hit-single "Decode" as the video screen showed the band running through the forest with fireworks and flares, the video has been described as a part-two to the songs music video. After that Hayley Williams and Josh Farro moved to stage left and performed an acoustic cover of Loretta Lynn's "You Ain't Women Enough." After that, a red couch (similar to the one on the cover of All We Know is Falling) and a small lamp were brought out and the band performed a three song acoustic set, during this the light bulbs from Ignorance were brought down again to illuminate the stage. After that the band returned with "Let the Flames Begin" while the video screens showed images of open hands during the 'Oh Father' outro. They then performed "Crushcrushcrush" and "Pressure " stopping in the bridge during "Pressure" for Hayley to introduce all the band members, and for Josh to introduce Hayley. They then performed "Looking Up" while each of the video screens showed lyrics to the song and each of the band members daily lives, at the end of the song all the members came together to ride bikes as the split-screens faded away. They then ended their main set with their biggest hit "The Only Exception" as pyrotechnics were used during the last chorus of the song. The band then exited and come back for an encore, starting with "Brick By Boring Brick" while the video screens showed various images, including deserts, snakes, the Brand New Eyes butterfly, and hot air balloons. After "Brick" the band concluded their set with their breakthrough song "Misery Business" as flashing images of the "Riot!" logo filled the video screens, during the bridge Williams would let one, or sometimes various fans on stage to sing the rest of the song or sometimes play guitar, and as the last chorus came in confetti cannons were shot towards the crowd. The set concluded with the video screen showing Paramore's logo and the band bowing then leaving the stage. They used the same production for their Oceania and UK tours.

Example Input: Question: How many times did Kurt Angle win the NWA Heavyweight Championship? Passage:The Impact World Championship is a professional wrestling world championship owned by the promotion Impact Wrestling, formerly Total Nonstop Action Wrestling (TNA). From June 2002 to May 2007, TNA used the NWA World Heavyweight Championship as their primary championship due to an agreement with the National Wrestling Alliance (NWA). On May 13, 2007, the NWA abruptly ended the arrangement and retrieved control of the NWA World Heavyweight Championship. On the same night, TNA were set to host their annual Sacrifice pay-per-view event, in which the NWA World Heavyweight Championship was to be defended by then-champion Christian Cage against Kurt Angle and Sting in a three-way match. Angle won the match and on the following episode of TNA's television program Impact! on May 17, was declared the new TNA World Heavyweight Champion. He was stripped of the championship later in the program, with Management Director Jim Cornette citing a problematic finish to the title match. The ownership of the championship was decided on June 17, 2007 at TNA's Slammiversary event in a King of the Mountain match involving Angle and Cage along with A.J. Styles, Chris Harris and Samoa Joe, which Angle won.

Example Input: Question: How long did the Teutonic Knights control the Chelmno Land? Passage:At the beginning of the 13th century, a Prussian trade route developed that crossed over an isthmus between two large lakes, the Sicieńskie lake and the Zamkowe ("Castle lake"). A defensive wall was built at this spot, and later, a settlement was constructed there as well. The place is mentioned in a twelfth-century document regarding a battle in which Henry of Sandomierz was killed. Under the name "Wambresia" the town was mentioned in a 1251 Prussian Document issued at Chełmża. Bishop Heidenreich of Bishopric of Chełmno received the Chełmno Land from the pope. The Polish duke Konrad I of Masovia turned possession of the settlement over to the bishop of Chełmno. This created a problem because the Teutonic Knights were in control of the Chełmno Land, and a dispute began between the Bishop of Chełmno and the Knights. The Pope at the time, Innocent IV, was not keen to continue the dispute and installed the Bishop as the rightful ruler of the settlement. This disagreement was the first historical mention of the settlement. In 1251, a large church, St. Simon and Judah, was built in the city.
