Task: Question Generation
Input (English): Passage: Discovery then proceeded westward in search of permanent quarters. On 8 February she entered McMurdo Sound and later that day anchored in a spot near its southern limit which was afterwards christened Winter Quarters Bay. Wilson wrote: "We all realized our extreme good fortune in being led to such a winter quarter as this, safe for the ship, with perfect shelter from all ice pressure." Stoker Lashly, however, thought it looked "a dreary place." Work began ashore with the erection of the expedition's huts on a rocky peninsula designated Hut Point. Scott had decided that the expedition should continue to live and work aboard ship, and he allowed Discovery to be frozen into the sea ice, leaving the main hut to be used as a storeroom and shelter.Of the entire party, none were skilled skiers and only Bernacchi and Armitage had any experience with dog-sledges. The results of the men's early efforts to master these techniques were not encouraging, and tended to reinforce Scott's preference for man-hauling. The dangers of the unfamiliar conditions were confirmed when, on 11 March, a party returning from an attempted journey to Cape Crozier became stranded on an icy slope during a blizzard. In their attempts to find safer ground, one of the group, Able Seaman George Vince, slid over the edge of a cliff and was killed. His body was never recovered; a cross with a simple inscription, erected in his memory, still stands at the summit of the Hut Point promontory.During the winter months of May–August the scientists were busy in their laboratories, while elsewhere equipment and stores were prepared for the next season's work. For relaxation there were amateur theatricals, and educational activities in the form of lectures. A newspaper, the South Polar Times, was edited by Shackleton. Outside pursuits did not cease altogether; there was football on the ice, and the schedule of magnetic and meteorological observations was maintained. As winter ended, trial sledge runs resumed, to test equipment and rations in advance of the planned southern journey which Scott, Wilson and Shackleton were to undertake. Meanwhile, a party under Royds travelled to Cape Crozier to leave a message at the post there, and discovered an emperor penguin colony. Another group, under Armitage, reconnoitred in the mountains to the west, returning in October with the expedition's first symptoms of scurvy. Armitage later blamed the outbreak on Scott's "sentimental objection" to the slaughter of animals for fresh meat. The entire expedition's diet was quickly revised, and the trouble was thereafter contained.
Output (English): What did the Discovery's crew make changes to that saved them from scurvy?
