Instructions: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Input: Passage: After reporting Amundsen's arrival to Scott at Cape Evans, Campbell's Eastern party became the "Northern Party". On 9 February 1911 they sailed northwards, arriving at Robertson Bay, near Cape Adare on 17 February, where they built a hut close to Norwegian explorer Carstens Borchgrevink's old quarters.
The Northern Party spent the 1911 winter in their hut. Their exploration plans for the summer of 1911–1912 could not be fully carried out, partly because of the condition of the sea ice and also because they were unable to discover a route into the interior. Terra Nova returned from New Zealand on 4 January 1912, and transferred the party to the vicinity of Evans Cove, a location approximately 250 miles (400 km) south of Cape Adare and 200 miles (320 km) northwest of Cape Evans. They were to be picked up on 18 February after the completion of further geological work, but due to heavy pack ice, the ship was unable to reach them. The group, with meagre rations which they had to supplement by fish and seal meat, were forced to spend the winter months of 1912 in a snow cave which they excavated on Inexpressible Island. Here they suffered severe privations—frostbite, hunger, and dysentery, with extreme winds and low temperatures, and the discomfort of a blubber stove in confined quarters.On 17 April 1912 a party under Edward Atkinson, in command at Cape Evans during the absence of the polar party, went to relieve Campbell's party, but were beaten back by the weather. The Northern Party survived the winter in their icy chamber, and set out for the base camp on 30 September 1912. Despite their physical weakness, the whole party managed to reach Cape Evans on 7 November, after a perilous journey which included a crossing of the difficult Drygalski Ice Tongue. Geological and other specimens collected by the Northern Party were retrieved from Cape Adare and Evans Cove by Terra Nova in January 1913.
Output:
What were the severe privations the group suffered?
