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.
One example: 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 is here: 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.

Now, solve this: Passage: The end of Patience Camp was signalled on the evening of 8 April, when the floe suddenly split. The camp now found itself on a small triangular raft of ice; a break-up of this would mean disaster, so Shackleton readied the lifeboats for the party's enforced departure. He had now decided they would try, if possible, to reach the distant Deception Island because a small wooden church had been reportedly erected for the benefit of whalers. This could provide a source of timber that might enable them to construct a seaworthy boat.At 1 p.m. on 9 April, the Dudley Docker was launched, and an hour later all three boats were away. Shackleton himself commanded the James Caird, Worsley the Dudley Docker, and navigating officer Hubert Hudson was nominally in charge of the Stancomb Wills, though because of his precarious mental state the effective commander was Tom Crean.The boats were surrounded by ice, dependent upon leads of water opening up, and progress was perilous and erratic. Frequently the boats were tied to floes, or dragged up onto them, while the men camped and waited for conditions to improve. Shackleton was wavering again between several potential destinations, and on 12 April, rejected the various island options and decided on Hope Bay, at the very tip of Graham Land. However, conditions in the boats, in temperatures sometimes as low as −20 °F (−29 °C), with little food and regular soakings in icy seawater, were wearing the men down, physically and mentally. Shackleton therefore decided that Elephant Island, the nearest of the possible refuges, was now the most practical option.On 14 April, the boats lay off the south-east coast of Elephant Island, but could not land as the shore consisted of perpendicular cliffs and glaciers. Next day the James Caird rounded the eastern point of the island, to reach the northern lee shore, and discovered a narrow shingle beach. Soon afterwards, the three boats, which had been separated during the previous night, were reunited at this landing place. It was apparent from high tide markings that this beach would not serve as a long-term camp, so the next day Wild and a crew set off in the Stancomb Wills to explore the coast for a safer site. They returned with news of a long spit of land, seven miles (11 km) to the west. With minimum delay the men returned to the boats and transferred to this new location, which they later christened Cape Wild.
Solution:
What was the full name of the person with a precarious mental state?
