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.

Passage: When charter-boat skipper Jack O'Conner finds a gold Spanish dollar off the Florida Keys, he decides to go in search of a legendary hoard of Spanish doubloons sunk during the "Hundred Years Storm" of 1780. For, as Jack's friend Cap'n Billau reveals, the coin bears a clue to the treasure's whereabouts – one of four islands etched by the infamous pirate, Jacques Un-Oeil upon the original doubloon. At Billau's urging, Jack tracks down the two beautiful women who unknowingly hold the remaining clues.
Streetwise Sandy Sequoia's piece of eight came from her murdered drug dealer boyfriend in Miami. And lonely-heart Portia Pennington inherited her coin from her merchant tycoon grandfather, who died at sea in the "Hundred Years Storm" of 1893, while hunting for the lost gold.
Jack convinces the girls to go in search of the pirate treasure with him. But first, the two must learn to crew his 76' schooner; and then, all three adventurers must learn to trust one another, if they expect to navigate the treacheries of love and the unpredictable Caribbean.
As Jack introduces the girls to life at sea, he starts to fall in love with Sandy. All seems to be going well, until Jack discovers Sandy with drugs on his boat – a kilo of her dead boyfriend's cocaine (which she has steadily been using since coming aboard). He has Portia dump the coke overboard; and while Sandy wrestles to overcome her addiction, Jack turns his attentions to Portia.
When Sandy and Portia realize that Jack has seduced each of them in turn and convinced each to reveal to him the name of the island on her coin, they turn on him. Feeling betrayed and realizing that they no longer need Jack in order to sail the boat or find the gold, they maroon him on a small island and go after the sunken treasure themselves.

Passage: William Etty was born in 1787 in York, the son of a miller and baker. He showed artistic promise from an early age, but his family were financially insecure, and at the age of 12 he left school to become an apprentice printer in Hull. On completing his seven-year indenture he moved to London "with a few pieces of chalk-crayons in colours", with the aim of emulating the Old Masters and becoming a history painter. Etty gained acceptance to the Royal Academy Schools in early 1807. After a year spent studying under renowned portrait painter Thomas Lawrence, Etty returned to the Royal Academy, drawing at the life class and copying other paintings. In 1821 the Royal Academy exhibited one of Etty's works, The Arrival of Cleopatra in Cilicia (also known as The Triumph of Cleopatra). The painting was extremely well received, and many of Etty's fellow artists greatly admired him. He was elected a full Royal Academician in 1828, ahead of John Constable. He became well respected for his ability to capture flesh tones accurately in painting and for his fascination with contrasts in skin tones.
Following the exhibition of Cleopatra, Etty attempted to reproduce its success, concentrating on painting further history paintings containing nude figures. He exhibited 15 paintings at the Summer Exhibition in the 1820s (including Cleopatra), and all but one contained at least one nude figure. In so doing Etty became the first English artist to treat nude studies as a serious art form in their own right, capable of being aesthetically attractive and of delivering moral messages. Although some nudes by foreign artists were held in private English collections, Britain had no tradition of nude painting, and the display and distribution of nude material to the public had been suppressed since the 1787 Proclamation for the Discouragement of Vice. The supposed prurient reaction of the lower classes to his nude paintings caused concern throughout the 19th century. Many critics condemned his repeated depictions of female nudity as indecent, although his portraits of male nudes were generally well received. (Etty's male nude portraits were primarily of mythological heroes and classical combat, genres in which the depiction of male nudity was considered acceptable in England.) From 1832 onwards, needled by repeated attacks from the press, Etty remained a prominent painter of nudes but made conscious efforts to try to reflect moral lessons in his work.

Passage: The four officers were taken aback by Taylor's searing words and felt they had been humiliated. A decade after the incident, Kỳ described Taylor as "the sort of man who addressed people rather than talked to them", referencing the confrontation. Karnow said "For the sake of their own pride, they [the Vietnamese officers] resented being treated in ways that reminded them of their almost total dependence on an alien power. How could they preserve a sense of sovereignty when Taylor, striving to push them into 'getting things done', behaved like a viceroy?" However, Thi also took a perverse pleasure in riling Taylor. He was seen by a CIA officer soon after, grinning. When asked why he was happy, Thi said "Because this is one of the happiest days of my life ... Today I told the American ambassador that he could not dictate to us." Nevertheless, Taylor's conduct had rankled the officers, stirring their latent sense of nationalism and anti-Americanism; Khánh would exploit this to strengthen his fragile position in the junta.Khánh's quartet of delegates responded to Taylor in a circumlocutory way. They remained calm and did not resort to direct confrontation. Kỳ said the change was necessary, as "the political situation is worse than it ever was under Diệm". Kỳ explained that the situation mandated the dissolution of the council, saying "We know you want stability, but you cannot have stability until you have Unity." He claimed some HNC members were disseminating coup rumors and creating doubt among the population, and that "both military and civilian leaders regard the presence of these people in the High National Council as divisive of the Armed Forces due to their influence". Kỳ further accused some of the HNC members of being communist sympathizers and cowards who wanted to stop the military from strengthening. He promised to explain the decision at a media conference and vowed that he and his colleagues would return to purely military roles in the near future. Thiệu added "I do not see how our action has hurt the Hương government ... Hương now has the full support of the Army and has no worries from the High National Council, which we have eliminated." Cang said "It seems ... we are being treated as though we were guilty. What we did was only for the good of the country."When Taylor said the moves detracted from Hương and Suu's powers, the officers disagreed and said they supported the pair in full and that Hương had approved of the HNC's dissolution. Taylor was unimpressed by the reassurances, concluding with "I don't know whether we will continue to support you after this ... You people have broken a lot of dishes and now we have to see how we can straighten out this mess." Taylor's deputy, U. Alexis Johnson felt the discussion had become counterproductive and was increasing the problem. He suggested that should the generals feel unwilling to alter their position immediately, they should refrain from actions that would preclude a later change of heart. He proposed they merely announce the removal of certain members of the HNC rather than the dissolution of the entire body, hoping the HNC could be reconstituted with figures they deemed to be more satisfactory. The four officers did not give a clear answer to Johnson's idea, indicating they had not made a concrete decision by saying "the door is not closed".
