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.

[Q]: Passage: In the late 19th and early 20th centuries, child vaudevillian Buster Keaton stays in boarding houses, rides in train boxcars, and performs with his mother and father in a knock-about (physical comedy) act called The Three Keatons. As a young man Keaton travels on his own to Hollywood and tricks his way onto the grounds of silent-film studio Famous Studio as a workman carrying a board, as in one of his trademark comic bits. 
Sneaking onto a set, he attracts the attention of a young casting director, Gloria Brent. He demonstrates his type of physical comedy to a director Kurt Bergner, whom he does not impress. But Gloria recognizes his talent and recommends him to studio head Larry Winters, who offers him a contract. Keaton begins to get small parts in other people's pictures. As his comic talent becomes more apparent and his fame and money-making power grows, he is offered a contract to direct and star in his own silent films.
Dissatisfied with not sharing the profits of his films, he is told that he must invest in his own pictures in order to profit-share. He does in "The Gambler", which is released at the same time as Al Jolson's blockbuster talkie, "The Jazz Singer", reducing public interest in it. Buster struggles to adapt to performing in talking pictures.
[A]: What is the full name of the person who fails to impress Kurt Bergner?


[Q]: Passage: In February 1828, shortly before his 41st birthday, Etty soundly defeated John Constable by 18 votes to five to become a full Royal Academician, at the time the highest honour available to an artist. By this time, complaints about his supposed indecency were beginning to resurface. All but one of the 15 paintings Etty exhibited at the Royal Academy in the 1820s had included at least one nude figure, and Etty was acquiring a reputation for using respectable themes as a pretext for nudity.For the 1828 Summer Exhibition Etty exhibited three pictures; The World Before the Flood, Venus, the Evening Star and Guardian Cherubs. (The latter was a portrait of the children of Welbore Ellis Agar, 2nd Earl of Normanton, and was the only non-nude painting exhibited by Etty at the RA in the 1820s.) Although similar to his earlier works, they were technically more accomplished. Both The World Before the Flood and Venus attracted positive reviews in the press and were sold during their exhibition for substantial sums, although the purchase by the Marquess of Stafford of The World Before the Flood—a work containing scantily clad figures of both sexes—drew a pointed comment in The Gentleman's Magazine that it "will serve to accompany the private Titians of that nobleman". Despite the increasing number of complaints in the press about his use of nudity, respect for Etty from his fellow artists continued to rise, and in 1828 the British Institution awarded him £100 in recognition of his talent.
As soon as the 1828 Summer Exhibition was over, Etty stopped work on other projects to concentrate on a diploma piece, without which he could not become a Royal Academician. This piece, Sleeping Nymph and Satyrs, was presented to the Academy in October, and in December 1828 Etty became a Royal Academician.
It appears to me then that virtuous happiness being our lawful aim in life, that having Academic Rank and Fame the next thing to be considered (if God approve) is to seek that Decent Competency which shall make my latter days comfortable and happy, which I hope if it please Him, to be able to do by the time I am fifty—by occasionally mixing with my historic pictures a Portrait or two, and to vary and extend my sphere—a classic Landscape or two so that if I can get about 100 a year I may be enabled to retire to my dear native city and spend my latter days in peace.
[A]: What is the exact title of the diploma piece without which Etty could not become a Royal Academician?


[Q]: Passage: Dean Corso, a New York City rare book dealer, makes his living conning people into selling him valuable antique books for a low price, and then re-selling them to private collectors. Corso meets with wealthy book collector Boris Balkan, who has recently acquired a copy of The Nine Gates of the Kingdom of Shadows by 17th-century author Aristide Torchia, one of only three extant copies. The author adapted the book from one written by the Devil himself, and was burned for heresy. "The Nine Gates" purportedly contains the means to summon the Devil and acquire invincibility and immortality. Balkan believes two of the three copies are forgeries. He hires Corso to check all three and acquire the legitimate one by any means necessary.
Balkan's copy was acquired from Andrew Telfer, who killed himself soon after. Telfer's widow Liana seduces Corso, in a failed attempt to get the book back. Meanwhile, Corso leaves the book for safekeeping with bookseller Bernie Rothstein, who is then murdered; his corpse is found posed like an engraving in The Nine Gates.
Corso travels to Toledo, Spain. The Ceniza brothers, book restorers who sold Balkan's copy to Telfer originally, show him that three of the nine engravings are signed "LCF", rather than "AT", which aligns with the rumors that Lucifer himself was Aristide Torchia's co-author, and implies Satan designed the three images personally.
[A]:
Whose book does the bookseller's body get posed like an engraving from?
