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: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Example output: Who believes Fagin's gang make wallets and handkerchiefs?.
Example explanation: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.
Q: Passage: In mid-1917 nine-year-old Frances Griffiths and her mother—both newly arrived in the UK from South Africa—were 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.
A:
What are the full names of the girls who had taken the photographs that Polly Wright showed at the meeting?
