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.

Example Input: Passage: A man unveils a valuable painting he picked up for $50,000 and is killed. A card with a large black ace (of spades) is put on his chest. Another "Black Ace" victim. The killer sends his victims a Black Ace card, warning them they are to die and then kills them, his way of taunting the police. Neil Broderick, an author, intends writing a book about him and is on his way to see Thornton Drake to get more information about him. Austin Winters is his secretary and Neil met his daughter Martha on the train, on the way to Chicago.
Drake has just received a Black Ace, with the words: "At seven tomorrow night", the time he is to be killed. Two plainclothes cops arrive from police headquarters, having had a call, Clancy and Dugan (both incompetents). Martha suggests that they leave for Drake's Louisiana plantation tomorrow morning and be far away from there at seven tomorrow night. Drake agrees and suggests they all go. On the flight, the lights go off for some seconds and when they come on again, Austin Winters is dead without a mark on him.
At the plantation, Clancy ineptly questions the suspects till Neil points out that they are now in another state, so out of their jurisdiction. Neil goes to another room and makes a phone call, then signals to someone outside. After he finishes his call, the line is cut. Meanwhile one of the pilots has taken off in the plane, leaving the other pilot, Henderson, behind who claims he does not know anything though he was out of the cockpit when Winters was killed.
The coroner finds a letter on the dead man which is to be read if Winters dies. It will reveal the identity of the Black Ace. Clancy starts reading it aloud and unsurprisingly the lights go off and the letter has vanished when the lights are turned on again. People locked in their rooms that night and Neil has a hidden car outside signal to him.
Example Output: Who is Neil Broderick writing a book about?

Example Input: Passage: The book Elvis: What Happened?, co-written by the three bodyguards fired the previous year, was published on August 1. It was the first exposé to detail Presley's years of drug misuse. He was devastated by the book and tried unsuccessfully to halt its release by offering money to the publishers. By this point, he suffered from multiple ailments: glaucoma, high blood pressure, liver damage, and an enlarged colon, each magnified—and possibly caused—by drug abuse.On the evening of Tuesday, August 16, 1977, Presley was scheduled to fly out of Memphis to begin another tour. That afternoon, Ginger Alden discovered him in an unresponsive state on a bathroom floor. According to her eyewitness account, "Elvis looked as if his entire body had completely frozen in a seated position while using the commode and then had fallen forward, in that fixed position, directly in front of it. [...] It was clear that, from the time whatever hit him to the moment he had landed on the floor, Elvis hadn't moved." Attempts to revive him failed, and his death was officially pronounced at 3:30 p.m. at the Baptist Memorial Hospital.President Jimmy Carter issued a statement that credited Presley with having "permanently changed the face of American popular culture". Thousands of people gathered outside Graceland to view the open casket. One of Presley's cousins, Billy Mann, accepted $18,000 to secretly photograph the corpse; the picture appeared on the cover of the National Enquirer's biggest-selling issue ever. Alden struck a $105,000 deal with the Enquirer for her story, but settled for less when she broke her exclusivity agreement. Presley left her nothing in his will.Presley's funeral was held at Graceland on Thursday, August 18. Outside the gates, a car plowed into a group of fans, killing two women and critically injuring a third. About 80,000 people lined the processional route to Forest Hill Cemetery, where Presley was buried next to his mother. Within a few weeks, "Way Down" topped the country and U.K. pop charts. Following an attempt to steal Presley's body in late August, the remains of both Presley and his mother were reburied in Graceland's Meditation Garden on October 2.
Example Output: What publication paid $105,00 for the story from the person that discovered Elvis in an unresponsive state?

Example Input: Passage: There was considerable overlap between panel painting and illumination; van Eyck, van der Weyden, Christus and other painters designed manuscript miniatures. In addition, miniaturists would borrow motifs and ideas from panel paintings; Campin's work was often used as a source in this way, for example in the "Hours of Raoul d'Ailly". Commissions were often shared between several masters, with junior painters or specialists assisting, especially with details such as the border decorations, these last often done by women. The masters rarely signed their work, making attribution difficult; the identities of some of the more significant illuminators are lost.Netherlandish artists found increasingly inventive ways to highlight and differentiate their work from manuscripts from surrounding countries; such techniques included designing elaborate page borders and devising ways to relate scale and space. They explored the interplay between the three essential components of a manuscript: border, miniature and text. An example is the Nassau book of hours (c. 1467–80) by the Vienna Master of Mary of Burgundy, in which the borders are decorated with large illusionistic flowers and insects. These elements achieved their effect by being broadly painted, as if scattered across the gilded surface of the miniatures. This technique was continued by, among others, the Flemish Master of James IV of Scotland (possibly Gerard Horenbout), known for his innovative page layout. Using various illusionistic elements, he often blurred the line between the miniature and its border, frequently using both in his efforts to advance the narrative of his scenes.During the early 19th century, the collection of 15th- and 16th-century Netherlandish cut-out, as miniatures or parts for albums, became fashionable amongst connoisseurs such as William Young Ottley, leading to the destruction of many manuscripts. Originals were highly sought after, a revival that helped the rediscovery of Netherlandish art in the later part of the century.
Example Output:
What is the name of the man that used an innovative page layout that often blurred the line between the miniature and its border?
