question: Which of the Antarctic region expeditions led by Robert Falcon Scott discovered The Knoll?
answer: the Discovery Expedition
context: Title: Ernest Joyce
  Passage: Ernest Edward Mills Joyce AM (about 1875 – 2 May 1940) was a Royal Naval seaman and explorer who participated in four Antarctic expeditions during the Heroic Age of Antarctic Exploration, early in the early 20th century.  He served under both Robert Falcon Scott and Ernest Shackleton.  As a member of the Ross Sea party in Shackleton's Imperial Trans-Antarctic Expedition, Joyce earned an Albert Medal for his actions in bringing the stricken party to safety, after a traumatic journey on the Great Ice Barrier.  He was awarded the Polar Medal with four bars, one of only two men to be so honoured, the other being his contemporary, Frank Wild.
  Title: Robert Falcon Scott
  Passage: Captain Robert Falcon Scott, (6 June 1868 – 29 March 1912) was a British Royal Navy officer and explorer who led two expeditions to the Antarctic regions: the Discovery Expedition (1901–1904) and the ill-fated Terra Nova Expedition (1910–1913).  On the first expedition, he set a new southern record by marching to latitude 82°S and discovered the Polar (Antarctic) Plateau, on which the South Pole is located.  On the second venture, Scott led a party of five which reached the South Pole on 17 January 1912, four weeks after Roald Amundsen's Norwegian expedition.  On their return journey, Scott's party discovered plant fossils, proving Antarctica was once forested and joined to other continents.  A planned meeting with supporting dog teams from the base camp failed, despite Scott's written instructions, and at a distance of 150 miles from their base camp and 11 miles from the next depot, Scott and his companions perished.
  Title: Ernest Shackleton
  Passage: Sir Ernest Henry Shackleton ( ; 15 February 1874 – 5 January 1922) was a polar explorer who led three British expeditions to the Antarctic, and one of the principal figures of the period known as the Heroic Age of Antarctic Exploration.  Born in Kilkea, Athy, County Kildare, Ireland, Shackleton and his Anglo-Irish family moved to Sydenham in suburban south London when he was ten.  His first experience of the polar regions was as third officer on Captain Robert Falcon Scott's Discovery Expedition 1901–1904, from which he was sent home early on health grounds, after he and his companions Scott and Edward Adrian Wilson set a new southern record by marching to latitude 82°S.
  Title: Hoosh
  Passage: Hoosh (occasionally spelt hooch) is a thick stew made from pemmican (a mix of dried meat, fat, and cereal) or other meat, thickener such as ground biscuits, and water.  It was the common food of early twentieth century Antarctic expeditions, used, for example, by the expeditions of Robert Falcon Scott (1910–1913) and Ernest Shackleton (1914–1916).
  Title: The Knoll
  Passage: The Knoll ( ) is a snow-free knoll, 370 m high, surmounting Cape Crozier at the eastern extremity of Ross Island, Antarctica.  It was discovered and named by the British National Antarctic Expedition, 1901–04, under Robert Falcon Scott.
