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: Beginning on December 11, 1945, Stafford hosted the Tuesday and Thursday broadcasts of NBC musical variety radio program The Chesterfield Supper Club. On April 5, 1946, the entire cast, including Stafford and Perry Como, participated in the first commercial radio broadcast from an airplane. The initial plan was to use the stand-held microphones used in studios but when these proved to be problematic, the cast switched to hand-held microphones, which because of the plane's cabin pressure became difficult to hold. Three flights were made that day; a rehearsal in the afternoon, then two in the evening—one for the initial 6:00 pm broadcast and another at 10:00 pm for the West Coast broadcast.Stafford moved from New York to California in November 1946, continuing to host Chesterfield Supper Club from Hollywood. In 1948, she restricted her appearances on the show to Tuesdays, and Peggy Lee hosted the Thursday broadcasts. Stafford left the show when it was expanded to 30 minutes, making her final appearance on September 2, 1949. She returned to the program in 1954; it ended its run on NBC Radio the following year. During her time with Chesterfield Supper Club, Stafford revisited some of the folk music she had enjoyed as a child. Weston, her conductor on the programme, suggested using some of the folk music for the show. With her renewed interest in folk tunes came an interest in folklore; Stafford established a contest to award a prize to the best collection of American folklore submitted by a college student. The annual Jo Stafford Prize for American Folklore was handled by the American Folklore Society, with the first prize of $250 awarded in 1949.

A: What was the name of the person that conducted the Chesterfield Supper Club?

Q: Passage: A five-movement ballet occurred somewhere in Act II, staged by W. H. Payne. A heading in the libretto, "Chorus and Ballet", attaches it to the last section of the finale but does not indicate how it figured in the plot. Most press accounts placed it at about this point, although some placed it slightly earlier in the act. At some performances, the ballet was performed in Act I, but it was certainly in Act II on opening night, and it seems finally to have settled there.In 1990, Roderick Spencer and Selwyn Tillett discovered the ballet from Act II of Thespis. Two of the five movements, in the same hand that had copied the score of "Climbing over rocky mountain", were found together with the surviving performance materials for Sullivan's 1864 ballet, L'Île Enchantée. Another section was found in the material for his 1897 ballet, Victoria and Merrie England. The page numbering of the surviving three sections gave approximate lengths for the missing pieces, and a contemporary engraving, seen at left, along with other circumstantial evidence, allowed plausible identifications of the two remaining movements: a dragon costume, used nowhere in the libretto, is presumably from the ballet, and the harp visible in the orchestra pit was an unusual instrument for the Gaiety's orchestra. Movements of appropriate length that made sense of these oddities were found in Sullivan's other ballets, and the reconstructed ballet has been recorded twice on CD.
Sullivan tended to re-use his ballet music. Of the five movements that Tillett and Spencer identified, only one (the Waltz, No. 3) is not known to have been used in any other work. Three of the movements had previously been used in L'Île Enchantée. Two of those, and one other, were eventually re-used in Victoria and Merrie England. One was also used in his incidental music to Macbeth. Sullivan was asked in 1889 to supply a ballet for a French-language production of The Mikado in Brussels, which he duly did. Tillett suggests that the Thespis ballet was almost certainly the music that Sullivan provided, given that it was the only ballet that he wrote for use in an opera, and that three weeks after producing The Gondoliers he is unlikely to have written something original.

A: What were the name of the two movements discovered by Spencer and Tillett?

Q: Passage: At the end of the 19th century, several forms of industrial development shaped Minnesota.  In 1882, a hydroelectric power plant was built at Saint Anthony Falls, marking one of the first developments of hydroelectric power in the United States.  Iron mining began in northern Minnesota with the opening of the Soudan Mine in 1884.  The Vermilion Range was surveyed and mapped by a party financed by Charlemagne Tower.  Another mining town, Ely began with the foundation of the Chandler Mine in 1888.  Soon after, the Mesabi Range was established when ore was found just under the surface of the ground in Mountain Iron.  The Mesabi Range ultimately had much more ore than the Vermilion Range, and it was easy to extract because the ore was closer to the surface.  As a result, open-pit mines became well-established on the Mesabi Range, with 111 mines operating by 1904.  To ship the iron ore to refineries, railroads such as the Duluth, Missabe and Iron Range Railway were built from the iron ranges to Two Harbors and Duluth on Lake Superior.  Large ore docks were used at these cities to load the iron ore onto ships for transport east on the Great Lakes.  The mining industry helped to propel Duluth from a small town to a large, thriving city.  In 1904, iron was discovered in the Cuyuna Range in Crow Wing County.  Between 1904 and 1984, when mining ceased, more than 106 million tons of ore were mined.  Iron from the Cuyuna Range also contained significant proportions of manganese, increasing its value.

A:
What is the industrial development that occurred in the Mesabi Range?
