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: The chain of craters has been the subject of several writers and naturalists. Mark Twain visited Mono Basin in the 1860s and wrote about Mono Lake, but did not mention any of the Mono–Inyo Craters except for the lake's two volcanic islands. He wrote in Roughing It (1872) that the lake was in a "lifeless, hideous desert ..." that was the "loneliest spot on earth ... little graced with the picturesque."
Naturalist John Muir explored the area in 1869. He described the "Mono Desert" as a "... country of wonderful contrasts. Hot deserts bounded by snow-laden mountains,—cinders and ashes scattered on glacier-polished pavements,—frost and fire working together in the making of beauty. In the lake are several volcanic islands, which show that the waters were once mingled with fire."  Muir described the Mono Craters as "... heaps of loose ashes that have never been blest by either rain or snow ..."In the spring of 1881 and the fall of 1882, geologist Israel Russell studied the area as a side-trip during his field research of Lake Lahontan, a now dry lake that covered much of nearby Nevada during the last glacial period. His Quaternary History of the Mono Valley (1889), which included a topographic survey by Willard D. Johnson, was the first thorough scientific description of Mono Lake and its volcanic features.
Russell named the Mono Craters and wrote: "The attention of every one who enters Mono Valley is at once attracted by the soft, pleasing colors of these craters as well as by the symmetry and beauty of their forms. They are exceptional features in the scenery of the region, and are rendered all the more striking by their proximity to the angular peaks and rugged outlines of the High Sierra.".

Q: 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.

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

Q: Passage: On a flight to New York for an annual police convention, Chan encounters his old Scotland Yard friend, Hugh Drake. Drake is now a member of military intelligence trying to track down what he believes is a sabotage ring led by a Paul Narvo. A bomber and its pilots crashed the day before. Chan offers his assistance.
Chan is welcomed at the airport by New York Police Inspector Vance and, to Chan's surprise, his number two son Jimmy Chan.
Chan goes to see Drake the next day at the apartment of George Kirby, where a dinner party is in progress. He finds his friend dead of poison gas in Drake's library, where he had gone to do some work. Drake's briefcase, containing all the information he had gathered about the sabotage ring, is missing. The window is latched, so Chan concludes one of the guests is responsible. Chan discovers that Drake asked that his Oxford classmate Herbert Fenton, actress June Preston and Ralph Percy, chief designer at the Metropolitan Aircraft Corporation, be invited to the party. Kirby himself is the company president. The lost bomber crashed at the company's plant. Also present is stockbroker Keith Jeffery. A servant reports chemist David Elliot insisted on seeing Drake, so he showed him in.
Chan learns that Preston also spoke with Drake that night, on behalf of a friend, Patricia Shaw. Shaw, it turns out, married Narvo in India. When she found out Narvo was involved in sabotage, she fled, only to be pursued by her husband and his assistant, Ramullah.
Ramullah is eventually tracked down, with Shaw's help, and taken into custody. (During a police lineup of Indians, Shorty McCoy, aka "The Canarsie Kid", [Shemp Howard] is revealed to be a faker, not a fakir.) Before Ramullah can be questioned, however, he is shot and killed. Shaw narrowly avoids the same fate.

A:
What is the name of the person who finds his friend dead of poison gas?
