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.

Question: Passage: In September 1970 Britten asked Myfanwy Piper, who had adapted the two Henry James stories for him, to turn another prose story into a libretto. This was Thomas Mann's novella Death in Venice, a subject he had been considering for some time. At an early stage in composition Britten was told by his doctors that a heart operation was essential if he was to live for more than two years. He was determined to finish the opera and worked urgently to complete it before going into hospital for surgery. His long-term colleague Colin Graham wrote:
Perhaps of all his works, this one went deepest into Britten's own soul: there are extraordinary cross-currents of affinity between himself, his own state of health and mind, Thomas Mann, Aschenbach (Mann's dying protagonist), and Peter Pears, who must have had to tear himself in three in order to reconstitute himself as the principal character.
After the completion of the opera Britten went into the National Heart Hospital and was operated on in May 1973 to replace a failing heart valve. The replacement was successful, but he suffered a slight stroke, affecting his right hand. This brought his career as a performer to an end. While in hospital Britten became friendly with a senior nursing sister, Rita Thomson; she moved to Aldeburgh in 1974 and looked after him until his death.Britten's last works include the Suite on English Folk Tunes "A Time There Was" (1974); the Third String Quartet (1975), which drew on material from Death in Venice; and the dramatic cantata Phaedra (1975), written for Janet Baker.In June 1976, the last year of his life, Britten accepted a life peerage the first composer so honoured becoming Baron Britten, of Aldeburgh in the County of Suffolk. After the 1976 Aldeburgh Festival, Britten and Pears travelled to Norway, where Britten began writing Praise We Great Men, for voices and orchestra based on a poem by Edith Sitwell. He returned to Aldeburgh in August, and wrote Welcome Ode for children's choir and orchestra. In November, Britten realised that he could no longer compose. On his 63rd birthday, 22 November, at his request Rita Thomson organised a champagne party and invited his friends and his sisters Barbara and Beth, to say their goodbyes to the dying composer. When Rostropovich made his farewell visit a few days later, Britten gave him what he had written of Praise We Great Men.
Britten died of congestive heart failure on 4 December 1976. His funeral service was held at Aldeburgh Parish Church three days later, and he was buried in its churchyard, with a gravestone carved by Reynolds Stone. The authorities at Westminster Abbey had offered burial there, but Britten had made it clear that he wished his grave to be side by side with that, in due course, of Pears. A memorial service was held at the Abbey on 10 March 1977, at which the congregation was headed by Queen Elizabeth The Queen Mother.

Answer: Who worked urgently to complete their opera before going into hospital for surgery?

Question: Passage: In early 1900s Cincinnati, young and beautiful Ray Schmidt works in her father's shop by day and stays out late drinking beer and dancing with various men by night, although her stepmother disapproves. Ray dates for fun, mostly going out with traveling salesmen passing through town, and neither she nor her dates are interested in any permanent attachment. An exception is Kurt Shendler, who owns a bicycle shop near Mr. Schmidt's shop and aspires to get into the automobile business. Kurt is in love with Ray and asks her to marry him, but she refuses because while she likes Kurt, she doesn't return his romantic feelings.
While visiting the train station with Kurt, Ray meets Walter Saxel and the two fall for each other at first sight. Walter soon confesses to Ray that he is actually engaged to another woman in town, Corinne, who comes from a wealthy background and whose mother is friends with his own mother. Nevertheless he has fallen in love with Ray, and asks her to meet him at a local band concert that he will be attending with his mother. Walter hopes to introduce Ray to his mother and perhaps get her approval of the relationship. On the day of the concert, Ray is late arriving because her younger half-sister Freda is suicidal over her boyfriend, Hugo, leaving town. Freda begs Ray to go after Hugo and stop him, threatening to throw herself out a window if Ray does not help. By the time Ray has dealt with Freda's situation and gotten to the concert, it is over, and Ray cannot find Walter or his mother in the departing crowds. Walter, thinking she stood him up, writes her an angry letter and marries Corinne.

Answer: What is the first name of the person who tends to her suicidal sister after her sister's boyfriend leaves town?

Question: Passage: Peter Hall directed the Bayreuth Ring after Chereau. His version, staged 198386, portrayed the natural innocence of the Rhinemaidens in the simplest of ways; they were naked. Keith Warner adapted this feature in his Ring production for the Royal Opera House Covent Garden, first staged 200406. A Covent Garden spokesman explained "The maidens are children of innocence, a vision of nature and as soon as someone appears they hastily throw on some clothes to protect their modesty." While Warner relies on lighting to achieve an underwater effect, Hall used a Pepper's ghost illusion: mirrors at a 45 angle made the Rhinemaidens appear to swim vertically when the performers were in fact swimming horizontally in a shallow basin.Although the roles of the Rhinemaidens are relatively small, they have been sung by notable singers better known for performing major roles in Wagnerian and other repertoire. The first person to sing the part of Woglinde in full was Lilli Lehmann at Bayreuth in 1876. In 1951, when the Bayreuth Festival re-opened after the Second World War, the same part was taken by Elisabeth Schwarzkopf. Other Bayreuth Rhinemaidens include Helga Dernesch who sang Wellgunde there between 1965 and 1967. Lotte Lehmann played Wellgunde at the Hamburg State Opera between 1912 and 1914 and the Vienna State Opera in 1916. Recorded Rhinemaidens have included Sena Jurinac for Furtwangler and RAI, Lucia Popp and Gwyneth Jones for Georg Solti, and Helen Donath and Edda Moser for Karajan.

Answer:
What is the first name of the person who used a Pepper's ghost illusion?
