Example Input: Question: Which of the two congregations which provided leadership to the Pilgrims was founded first? Passage:The Pilgrims or Pilgrim Fathers were English settlers who established Plymouth Colony in Plymouth, Massachusetts. Their leadership came from the religious congregations of Brownists, or Separatist Puritans, who had fled religious persecution in England for the tolerance of 17th-century Holland in the Netherlands. They held Puritan Calvinist religious beliefs but, unlike most other Puritans, they maintained that their congregations should separate from the English state church. They eventually determined to establish a new settlement in the New World and arranged with investors to fund them. They established Plymouth Colony in 1620, which became the second successful English settlement in America, following the founding of Jamestown, Virginia in 1607. The Pilgrims' story became a central theme in the history and culture of the United States.

Example Input: Question: How many songs on What To Do About Them had been previously unreleased? Passage:In 1992 the band signed to Taang! Records and released the eight-song mini-album What To Do About Them culled from a mix of previously available and unreleased home and studio recordings. Musician/cartoonist Ron Regé, Jr. contributed artwork to the album's cover as well as lo-fi recordings that were woven into the record's sequence. The band also set to work recording their first LP, around which time shifts in Swirlies' personnel began to occur. Ben Drucker only drummed on a third of the new album's studio tracks, and for the remaining songs his parts were handed over to a pair of session drummers. Andy Bernick departed to pursue ornithology for the academic year and Damon's former roommate Morgan Andrews filled in on bass guitar and other noises. It was this line-up that toured to support the new album, Blonder Tongue Audio Baton, and appeared in the video for its lead track, "Bell". Named for an obscure piece of vintage musical equipment, Blonder Tongue Audio Baton made use of Mellotron, Moog, and other analogue artifacts that the group had unearthed in the studio. During sequencing the band threw in numerous lo-fi compositions, soundbites, and rants, and collaged together an album jacket from arrays of found images and objects that matched the album's eclectic aesthetics. Hailed for melding "the high waters of shoegaze creativity and the mounting currents of indie rock", Blonder Tongue Audio Baton quickly rose to prominence in the American noise pop canon.
