Detailed 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.
See one example below:
Problem: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Solution: Who believes Fagin's gang make wallets and handkerchiefs?.
Explanation: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

Problem: Passage: The Aurora arrived at Cape Denison on 13 January 1913. When Mawson's party failed to return, Davis sailed her east along the coast as far as the Mertz Glacier tongue, searching for the party. Finding no sign and reaching the end of the navigable ice-free water, they returned to Cape Denison. The oncoming winter concerned Davis, and on 8 Februaryjust hours before Mawson's return to the hutthe ship departed Commonwealth Bay, leaving six men behind as a relief party. Upon Mawson's return, the Aurora was recalled by wireless radio, but powerful katabatic winds sweeping down from the plateau prevented the ship's boat from reaching the shore to collect the men.The Aurora returned to Cape Denison the following summer, in mid-December, to take the men home. The delay may have saved Mawson's life; he later told Phillip Law, then-director of Australian National Antarctic Research Expeditions (ANARE), that he did not believe he could have survived the sea journey so soon after his ordeal.The cause of Mawson and Mertz's illnesses remains in part a mystery. At the time, McLeanthe expedition's chief surgeon and one of the men who had remained at Cape Denisonattributed their sickness to colitis; Mawson wrote in The Home of the Blizzard, his official account of the expedition, that Mertz died of fever and appendicitis. A 1969 study by Sir John Cleland and R. V. Southcott of the University of Adelaide concluded that the symptoms Mawson describedhair, skin and weight loss, depression, dysentery and persistent skin infectionsindicated the men had suffered hypervitaminosis A, an excessive intake of vitamin A. This is found in unusually high quantities in the livers of Greenland Huskies, of which both Mertz and Mawson consumed large amounts.While hypervitaminosis A is the generally accepted medical diagnosis for Mertz's death and Mawson's illness, the theory has its detractors. Law believed it was "completely unproven ... The symptoms that were described are exactly the ones you get from cold exposure. You don't have to predicate a theory of this sort to explain the soles coming off your feet." A 2005 article in The Medical Journal of Australia by Denise Carrington-Smith suggested it may have been "the psychological stresses related to the death of a close friend and the deaths of the dogs he had cared for", and a switch from a predominately vegetarian diet that killed Mertz, not hypervitaminosis A.
Solution:
What were the last names of the men Cleland and Southcott indicated had suffered hypervitaminosis A?
