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 1916, childhood best friends, Bob Wilson and Fred von Bergen, are test pilots working for an American company that builds bombers for the European allies. Since he is German-born and faces prejudice against his heritage, Fred loses his job and, unable to find other employment, decides to return to Germany to fight for his homeland. Although he has no special attachment to the German cause, Bob quits the aviation company and joins his friend in Germany. 
On their way to a German airfield, Red Cross nurse Alida Hoffman accidentally runs Bob and Fred off the road, Both men are immediately drawn to Alida, especially Bob although Fred is more shy. After Bob's first unsuccessful mission, Captain Wolters, the squadron's tyrannical leader, expresses his doubt about his loyalty but, desperate for pilots, gives him another chance. 
As the United States is drawn into the war, instead of sending him into a crucial air battle, Wolters arrests Bob. Fred, heartbroken that Alida has chosen Bob, quarrels with his friend, calling him a coward. Later, however, Fred allows his friend to escape from a firing squad and flee to the Allied lines. 
To prove his allegiance, Bob leads British bombers to the German base, while Fred is told by Wolters that he must shoot down Bob to prove his loyalty. Neither man is capable of killing the other, and, in the end, Fred sacrifices his life for Bob. After the war, Bob returns to Germany to marry Alida. The newly married couple then returns to the United States, and pay their respects to Fred's mother.
[A]: What is the first name of the man that is fired for being German-born?


[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?


[Q]: Passage: Above the pylon, separated by the cornice, are the three Virtues—from left to right, Faith, Charity, and Hope—in shell niches, separated by four Corinthian fluted pilasters. Such a motif is unprecedented in Tuscan funerary sculpture but found at this date in Venice, Padua, and especially Cossa's native Naples. As a result, excursions to Venice have been suggested for both Michelozzo and Donatello. However, Janson suggests that one "need not go all the way to Venice" to find such motifs. Outside Florence, Virtues were common on tombs, with the cardinal Virtues used for laymen, and the theological virtues reserved for ecclesiastics, including the Brancaccio tomb. However, the Cossa Virtues, from their hair to their sandals, are more thoroughly antique. Donatello also produced two similar bronze Virtues for the Siena Baptistry, whose chronological relationship to the Cossa Virtues is unclear.The 1.05-metre (3.44 ft) tall Faith, to the right of Charity, is holding a Eucharistic chalice; the 1.07-metre (3.51 ft) tall Charity is holding a cornucopia and a brazier (or flaming vase); and the 1.06-metre (3.48 ft) tall Hope, to the left of Charity, has hands clasped in prayer. The central figure of Charity is the most antique, assimilating elements of Classical depictions of Abundantia, Ceres, and Juno, all of which were depicted with cornucopias in their left hands. Besides underscoring the antiquity of the tomb monument, the main purpose of the tall yet poorly finished Virtues is to put additional vertical distance between the viewer and the effigy, which has the cumulative effect of de-emphasizing the peculiarities of Cossa, in favor of a generic pontiff (i.e. a potential line of Florentine popes), by blunting the "immediacy" of the trope of lying in state, which was otherwise dominant on Quattrocento wall tombs.
[A]:
What is featured on the Brancaccio tomb?
