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: Despite undergoing various changes of emphasis, Bush's music retained a voice distinct from that of any of his contemporaries. One critic describes the typical Bush sound as "Mild dominant discords, of consonant effect, used with great originality in uncommon progressions alive with swift, purposeful harmonic movement ... except in [Benjamin] Britten they are nowhere used with more telling expression, colour and sense of movement than in Bush".John Ireland, Bush's early mentor, instilled "the sophisticated and restrained craftsmanship which marked Bush's music from the beginning", introducing him to folksong and Palestrina, both important building blocks in the development of Bush's mature style. Daula comments that "Bush's music does not [merely] imitate the sound-world of his Renaissance predecessors", but creates his unique fingerprint by "[juxtaposing] 16th century modal counterpoint with late- and post-romantic harmony".Bush's music, at least from the mid-1930s, often carried political overtones. His obituarist Rupert Christiansen writes that, as a principled Marxist, Bush "put the requirements of the revolutionary proletariat at the head of the composer's responsibilities", a choice which others, such as Tippett, chose not to make. However, Vaughan Williams thought that, despite Bush's oft-declared theories of the purposes of art and music, "when the inspiration comes over him he forgets all about this and remembers only the one eternal rule for all artists, 'To thine own self be true'.".
Example Output: What is the last name of the person who wrote that the composer who retained a voice distinct from that of any of his contemporaries "remembers only the one eternal rule for all artists, 'To thine own self be true'."?

Example Input: Passage: People have used resources on and around the MonoInyo Craters for centuries. Mono Paiutes gathered obsidian from the MonoInyo Craters to make sharp tools and arrow points. Unworked obsidian was carried by the Mono Paiutes over passes in the Sierra Nevada to trade with other Native American groups. Chips of MonoInyo obsidian can still be found at many ancient mountain campsites.
Gold rushrelated boomtowns sprang up near Mono Basin in the 19th century to exploit bonanzas. The largest of these, Bodie (north of Mono Lake), was founded in the late 1870s and grew large enough to need a tree mill, which was located at Mono Mills, immediately northeast of Mono Domes. Trees directly around the domes and on their slopes were felled to provide timber for the mill.
As part of the California Water Wars, the Los Angeles Department of Water and Power purchased large tracts of land in the 1930s within Mono Basin and Owens Valley in order to control water rights. Excavation of an 11.5-mile (18.5 km) water tunnel under the southern part of the Mono Craters dome complex started in 1934 and was completed in 1941. Tunnel workers had to deal with loose and often water-charged gravels, pockets of carbon dioxide gas and flooding. About one man was lost for each mile excavated. Water diverted from its natural outlet in Mono Lake passes through the tunnel on its way to the Los Angeles Aqueduct system.
The United States Pumice Company, based in Chatsworth, California, has mined the area for pumice since 1941. The company markets the pumice in slabs for use in commercial scouring and in large irregular chunks sold as yard decoration.Apollo 16's John Young and Charlie Duke did some of their geologic training here in June 1971. William R. Muehlberger was one of the geology instructors.Exploratory drilling for geothermal power occurred near the Mono Craters on the south shore of Mono Lake in 1971. The wells did not show promising results, so the effort was abandoned.
Example Output:
What is the full name of the company that markets pumice in slabs for use in commercial scouring?
