Example Input: Question: What country is the Bristol Channel located in? Passage:Because of the natural layout of the harbour, Ilfracombe became a significant safe port (registered port of refuge) on the Bristol Channel. It also had trade routes between Kinsale and Tenby, which made the port stronger. In 1208 it was listed as having provided King John with ships and men to invade Ireland; in 1247 it supplied a ship to the fleet that was sent to conquer the Western Isles of Scotland; 6 ships, with 79 men were sent to support the siege of Calais. Ilfracombe was the last disembarkation point for two large forces sent to subdue the Irish. The building which sits on Lantern Hill by the harbour, known as St Nicholas's Chapel (built 1361) is reputed to be the oldest working lighthouse in the UK; a light/beacon has been there for over 650 years. The town was also home to the Bowen family. James Bowen was master of HMS Queen Charlotte, the flagship of Richard, Earl Howe at the 1794 "Glorious First of June" battle. James Bowen was commissioned by Howe for his leadership in the battle, he rose through the levels - commander of the Argot, the Dreadnought, and in Georgian England titled "defender of Madeira", led the fleet which rescued the British army at Corunna in the Peninsula war, and retired as a Rear Admiral, Commissioner of the Royal Navy. Captain Richard Bowen (17611797) James Bowen's younger brother, a British naval commander on the ship HMS Terpsichore, served under Lord Nelson, and was killed at the battle of Santa Cruz de Tenerife. John Bowen (17801827), son of James Bowen, a naval officer and colonial administrator founded the first settlement of Tasmania at Risdon Cove in 1803 - the settlement which later became known as Hobart. Lieutenant A E Down, was initially posted to Ilfracombe to lead a protection ship for the customs and excise, he married a local girl, rose through the levels to retire as vice Admiral, his son joined the navy aged 14 (his first navy kit is on display at National Maritime Museum Greenwich). In 1802 James Meek married Down's daughter and settled in the town, James Meek was appointed the Comptroller of Victuals to the Royal Navy in 1832, he was knighted, and died in Ilfracombe 1852.

Example Input: Question: Which city that Trey Parker and Matt Stone commuted to has a larger population? Passage:The film opens as South Park creators Trey Parker and Matt Stone leave New York City and the 2011 opening night of their Broadway production The Book of Mormon to return to Los Angeles to begin the fifteenth season of South Park. The documentary chronicles the production of the season premiere, "HumancentiPad", beginning the Thursday prior to airing. Parker and Stone, alongside producers Anne Garefino, Vernon Chatman, Bill Hader, and Susan Arneson, discuss ideas for the episode. Parker mentions his annoyance with downloading the latest version of iTunes, and being forced to comply with the software's long list of terms and conditions. The rant leads to ideas, with Parker instructing the storyboard team on how to stage a shot. The film covers various aspects of production, including voice acting, animation, lip sync, communication with standards and practices, character design, and editing.

Example Input: Question: What is performed during the rite of passage? Passage:Traditional African religions like the Serer religion (A at Roog) are adhered to by devout worshippers of Roog the supreme deity in Serer religion. The Serer ethnic group who adhere to the tenets of Serer religion (including those Senegalese who syncretize) honour the Serer pangool and have ancient rituals and festivals devoted to them. The religious affairs of Serer religion devotees are usually headed by the Saltigue (the Serer priestly class) which in ancient times was the preoccupation of the Serer lamanic class. Some of these religious festivals or ceremonies include the Ndut (rite of passage), Xooy (divination festival once a year in Fatick), and the Raan festival. Senegalese hold several ancient beliefs, such as small efforts of 'thanks' or demands, such as protection from water. They also place great importance on the Baobab tree, which is known as the "House of the Spirits." The baobab tree along with other sacred trees figure prominently in the Serer creation narrative. Among the Jola people, some religious festivals include the Samay, Kumpo and the Niasse.
