instruction:
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.

Passage: In the 1960s, in an undetermined place in the Alps, an eagle couple has two hatching eggs. When both eaglets are born, their mother knows that she must only raise one as their successor. In an ensuing fight with another eagle, the eaglets' father dies when he crashes to the ground. One of the eaglets shortly falls from the nest, and his mother, due by nature to maintain the survivor, ignores the eaglet's cry for help.
In the meantime, forester Danzer meets with a boy named Lukas and his father Keller. They both live in a new house in the mountains, after the death of Maria, mother of Lukas and Keller's wife, as a result of a fire. Keller, gravely afflicted by the death of his wife, fails to live in harmony and understanding with his son, who takes refuge more and more in nature, avoiding contact with his father. As a retreat Lukas constantly goes to the remains of his old house, where he often sees the photograph of his deceased mother.
As Lukas' dog Scout is taking a walk in the forrest, Lukas comes across the eaglet, and Lukas decides to raise him to full health. Lukas takes the eaglet to his old house to take care of him. Danzer also meets the eaglet, and decides to help Lukas for the affection he feels for him.
The forester tells Lukas that the food he has given the eaglet is not good. He also tells him to give sunlight to the eaglet. When a fox sneaks in and kills Keller's hens, he angrily chases Lukas. Lukas, fearful for the safety of the eaglet, goes to his family's hut. Lukas rescues the eaglet from the attacking foxes. As Lukas stays and reads his family's Bible, he comes across the story of Cain and Abel. Aptly fitting the eaglet's own story, Lukas names it Abel.
answer:
Who was married to the father of the boy that the forester meets?

Passage: In February 1828, shortly before his 41st birthday, Etty soundly defeated John Constable by 18 votes to five to become a full Royal Academician, at the time the highest honour available to an artist. By this time, complaints about his supposed indecency were beginning to resurface. All but one of the 15 paintings Etty exhibited at the Royal Academy in the 1820s had included at least one nude figure, and Etty was acquiring a reputation for using respectable themes as a pretext for nudity.For the 1828 Summer Exhibition Etty exhibited three pictures; The World Before the Flood, Venus, the Evening Star and Guardian Cherubs. (The latter was a portrait of the children of Welbore Ellis Agar, 2nd Earl of Normanton, and was the only non-nude painting exhibited by Etty at the RA in the 1820s.) Although similar to his earlier works, they were technically more accomplished. Both The World Before the Flood and Venus attracted positive reviews in the press and were sold during their exhibition for substantial sums, although the purchase by the Marquess of Stafford of The World Before the Flooda work containing scantily clad figures of both sexesdrew a pointed comment in The Gentleman's Magazine that it "will serve to accompany the private Titians of that nobleman". Despite the increasing number of complaints in the press about his use of nudity, respect for Etty from his fellow artists continued to rise, and in 1828 the British Institution awarded him 100 in recognition of his talent.
As soon as the 1828 Summer Exhibition was over, Etty stopped work on other projects to concentrate on a diploma piece, without which he could not become a Royal Academician. This piece, Sleeping Nymph and Satyrs, was presented to the Academy in October, and in December 1828 Etty became a Royal Academician.
It appears to me then that virtuous happiness being our lawful aim in life, that having Academic Rank and Fame the next thing to be considered (if God approve) is to seek that Decent Competency which shall make my latter days comfortable and happy, which I hope if it please Him, to be able to do by the time I am fiftyby occasionally mixing with my historic pictures a Portrait or two, and to vary and extend my spherea classic Landscape or two so that if I can get about 100 a year I may be enabled to retire to my dear native city and spend my latter days in peace.
answer:
What is the exact title of the diploma piece without which Etty could not become a Royal Academician?

Passage: The highlight of Doubleday's career came after 7 February 1845 when a young man, who later admitted having spent the prior week "indulging in intemperance", smashed the Portland Vase, an example of Roman cameo glass and among the most famous glass items in the world, into hundreds of pieces. After his selection for the restoration, Doubleday commissioned a watercolour painting of the fragments by Thomas H. Shepherd. No account of his restoration survives, but on 1 May he discussed it in front of the Society of Antiquaries of London, and by 10 September he had glued the vase whole again. Only 37 small splinters, most from the interior or thickness of the vase, were left out; the cameo base disc, which was found to be a modern replacement, was set aside for separate display. A new base disc of plain glass, with a polished exterior and matte interior, was diamond-engraved "Broke Feby 7th 1845 Restored Sept 10th 1845 By John Doubleday". The British Museum awarded Doubleday an additional 25 (equivalent to 2,500 in 2016) for his work.At the time the restoration was termed "masterly" and Doubleday was lauded by The Gentleman's Magazine for demonstrating "skilful ingenuity" and "cleverness ... sufficient to establish his immortality as the prince of restorers". In 2006 William Andrew Oddy, a former keeper of conservation at the museum, noted that the achievement "must rank him in the forefront of the craftsmen-restorers of his time." Doubleday's restoration would remain for more than 100 years until the adhesive grew increasingly discoloured. The vase was next restored by J. W. R. Axtell in 19481949, and then by Nigel Williams in 19881989.
answer:
What was the first name of the person who was selected to restore the Portland Vase?
