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 company, retaining the title "Sadler's Wells Opera", opened at the Coliseum on 21 August 1968, with a new production of Mozart's Don Giovanni, directed by Sir John Gielgud. Though this production was not well received, the company rapidly established itself with a succession of highly praised productions of other works. Arlen died in January 1972, and was succeeded as managing director by Lord Harewood.The success of the 1968 Mastersingers was followed in the 1970s by the company's first Ring cycle, conducted by Goodall, with a new translation by Andrew Porter and designs by Ralph Koltai. The cast included Norman Bailey, Rita Hunter and Alberto Remedios. In Harewood's view, among the highlights of the first ten years at the Coliseum were the Ring, Prokofiev's War and Peace, and Richard Strauss's Salome and Der Rosenkavalier.
The company's musical director from 1970 to 1977 was Charles Mackerras. Harewood praised his exceptional versatility, with a range "from The House of the Dead to Patience." Among the operas he conducted for the company were Handel's Julius Caesar starring Janet Baker and Valerie Masterson; five Janacek operas; The Marriage of Figaro with pioneering use of 18th century performing style; Massenet's Werther; Donizetti's Mary Stuart with Baker; and Sullivan's Patience. The company took the production of the last to the Vienna Festival in 1975, along with Britten's Gloriana. Sir Charles Groves succeeded Mackerras as musical director from 1978 to 1979, but Groves was unwell and unhappy during his brief tenure. Starting in 1979, Mark Elder succeeded Groves in the post, and described Groves "immensely encouraging and supportive".A long-standing concern of Arlen and then Harewood was the need to change the company's name to reflect the fact that it was no longer based at Sadler's Wells theatre. Byam Shaw commented "The one major setback the Sadler's Wells Opera Company suffered from its transplant was that unheeding taxi drivers kept on taking their patrons up to Rosebery Avenue".Harewood considered it an elementary rule that "you must not carry the name of one theatre if you are playing in another one." Covent Garden, protective of its status, objected to the suggestion that the Sadler's Wells company should be called "The British National Opera" or "The National Opera", although neither Scottish Opera nor the Welsh National Opera opposed such a change. Eventually the British government decided the matter, and the title "English National Opera" was approved. The company's board adopted the new name in November 1974. In 1977, in response to demand for more opera productions in English provincial cities, a second company was established. It was based at Leeds in northern England, and was known as ENO North. Under Harewood's guidance, it flourished, and in 1981 it became an independent company, Opera North.

A: What name did the company that was titled "Sadler's Wells Opera" eventually change its name to?

Q: Passage: In the late 1830s, when much of the Old West was still Mexican territory, four people are traveling through the deserts, north of Texas and a three-day ride from Santa Fe.
One the Scalphunter, who says his trade is being a "buffaler" (buffalo hide trader). He is in search of gold. The others are a former ship Captain, also in search of the gold; the Woman from England, a former chambermaid who, in exchange for ship's passage to America, has signed an agreement to serve the Captain for five years as an indentured servant; and Mr. Rainbow, a former soldier who killed Indians.
The Captain sets out to find some of Montezuma's gold, risking danger from both the Native Indians and Mexican soldiers. The woman wants to get out of her contract with the Captain and go to New Orleans. She asks Mr. Rainbow to take her there, but he turns her down.
The Scalphunter wants half of the Captain's gold, and tags along with his men. Mr. Rainbow sets out across the desert through the Viaje de la Muerte, the Journey of Death.

A: What does the nickname for the trade of the man searching for gold actually refer to?

Q: Passage: The film opens in the year 1958, where steel heiress Edna Buxton enters a talent contest. Her overbearing mother is at odds with her, arguing that Edna should choose a specific song and wardrobe for the contest. At the contest, Edna swaps dresses with a blue singer named Doris, and even changes her song at the last minute, infuriating her mother, who leaves before seeing Edna win the competition.
An excited Edna decides to use her grand prize winnings to record a demo. The studio producer tactfully delivers the painful truth to Edna that not only are girl singers not getting signed, the record companies are trying to get rid of the ones currently on their rosters. However, when Edna tells him that she wrote the song, he is impressed enough to direct her to Joel Milner who takes her under his wing, renames her "Denise Waverly" and invents a blue-collar persona for her. Milner reworks her song for a male doo-wop group, the Stylettes, as male solo artists are groups are far more marketable. The song becomes a hit.
Denise (formerly Edna) moves to New York City and becomes a songwriter in the Brill Building. At a party, she meets the arrogant songwriter Howard Caszatt, and despite an awkward initial meeting they become romantically involved. She also reunites with Doris. Denise offers to and writes a song specifically for Doris and her two girlfriends, persuading Milner to audition and hire the group.
In 1965, Howard and Denise begin writing together; they pen a song called "Unwanted Number," based on a young girl's unwanted pregnancy. Although it is banned, it attracts the attention of prominent and influential disc jockey John Murray who, despite the negative attention of the song, credits Denise with sparking the craze for girl groups.

A:
What is the full name of the person that changes their song last minute?
