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: In mid-1917 nine-year-old Frances Griffiths and her motherboth newly arrived in the UK from South Africawere staying with Frances' aunt, Elsie Wright's mother, in the village of Cottingley in West Yorkshire; Elsie was then 16 years old. The two girls often played together beside the beck (stream) at the bottom of the garden, much to their mothers' annoyance, because they frequently came back with wet feet and clothes. Frances and Elsie said they only went to the beck to see the fairies, and to prove it, Elsie borrowed her father's camera, a Midg quarter-plate. The girls returned about 30 minutes later, "triumphant".Elsie's father, Arthur, was a keen amateur photographer, and had set up his own darkroom. The picture on the photographic plate he developed showed Frances behind a bush in the foreground, on which four fairies appeared to be dancing. Knowing his daughter's artistic ability, and that she had spent some time working in a photographer's studio, he dismissed the figures as cardboard cutouts. Two months later the girls borrowed his camera again, and this time returned with a photograph of Elsie sitting on the lawn holding out her hand to a 1-foot-tall (30 cm) gnome. Exasperated by what he believed to be "nothing but a prank", and convinced that the girls must have tampered with his camera in some way, Arthur Wright refused to lend it to them again. His wife Polly, however, believed the photographs to be authentic.
Towards the end of 1918, Frances sent a letter to Johanna Parvin, a friend in Cape Town, South Africa, where Frances had lived for most of her life, enclosing the photograph of herself with the fairies. On the back she wrote "It is funny, I never used to see them in Africa. It must be too hot for them there."The photographs became public in mid-1919, after Elsie's mother attended a meeting of the Theosophical Society in Bradford. The lecture that evening was on "fairy life", and at the end of the meeting Polly Wright showed the two fairy photographs taken by her daughter and niece to the speaker. As a result, the photographs were displayed at the society's annual conference in Harrogate, held a few months later. There they came to the attention of a leading member of the society, Edward Gardner. One of the central beliefs of theosophy is that humanity is undergoing a cycle of evolution, towards increasing "perfection", and Gardner recognised the potential significance of the photographs for the movement:
the fact that two young girls had not only been able to see fairies, which others had done, but had actually for the first time ever been able to materialise them at a density sufficient for their images to be recorded on a photographic plate, meant that it was possible that the next cycle of evolution was underway.
Example Output: What are the full names of the girls who had taken the photographs that Polly Wright showed at the meeting?

Example Input: Passage: Geophysicist Dr. Josh Keyes and scientists Dr. Serge Leveque and Dr. Conrad Zimsky become aware of an instability of Earth's magnetic field after a series of bizarre incidents across the globe. They determine that the Earth's molten core, which generates this field, has stopped rotating and that, within a year, the field will collapse, exposing the planet's surface directly to devastating solar radiation. Backed by the U.S. Government, Keyes, Leveque, and Zimsky create a plan to bore down to the core and set off several nuclear explosions to restart the rotation. They gain the help of rogue scientist Dr. Ed "Braz" Brazzelton, who has devised a vessel made of "Unobtainium" that can withstand the heat and pressure within the Earth's crust and convert it to energy, as well as a laser-driven boring system that will allow them to quickly pass through the crust.
Construction starts immediately on the Virgil, a multi-compartment vessel to be helmed by Space Shuttle Endeavour pilots Commander Robert Iverson and Major Rebecca "Beck" Childs, who will join Keyes and the others. To prevent a worldwide panic, Keyes enlists computer hacker Theodore Donald "Rat" Finch to scour the Internet and eliminate all traces of the pending disaster or their plan.
Example Output: What three people find out about the world's impending doom?

Example Input: Passage: Mexican revolutionary Pancho Villa finds himself without adequate funding to finance his war against the military-run government. He also finds himself at odds with the Americans because of the Hearst media empire's press campaign against him. To counter both of these threats, he sends emissaries to movie producers to convince them to pay to film his progress and the actual battles. Producer D.W. Griffith is immediately interested and convinces Mutual Film Studios boss Harry E. Aitkin to send a film crew. Aitkin's nephew Frank Thayer is initially a mere errand boy for the studio, but he makes a good impression with Villa, who demands that Thayer be placed in charge of the project. Thayer and a camera crew team film Villa leading his men to victory in battle. Despite the failure of this initial footage (which draws derisive laughter from potential backers) Thayer convinces Aitkin to invest even more money in a second attempt, and also convinces Villa to participate in making a more narrative film.
Thayer returns to Mexico with a director, actors, producers, cameramen and screen writers, and begin to film Villa's previous exploits using a younger actor, future film director Raoul Walsh. The filming goes well, although Villa becomes angry that the screenwriters and the director have changed history to make a more dramatic film. However, he agrees to do a cameo appearance as an older version of himself. Meanwhile, Thayer begins a romance with actress Teddy Sampson whom he's had a crush on since they first met. One night Villa announces that they will attack a Federal held fort at Torreon and win the revolution. The film's director and his crew tell Villa that they are not coming with him to film the battle. Villa scares them into going to the battle by having a firing squad shoot over their heads.
Example Output:
What is the last name of the person who agrees to do a cameo appearance as an older version of himself?
