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: 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: When Stephen Herrick, a sedate, mild-mannered shipping magnate, loses his opera tickets, Mrs. Grange, the aggressive mother of his fiancée Cecilia, insists upon being seated in the Herrick box anyway. Upon finding the Duncan family ensconced in their box, Mrs. Grange incites an argument that culminates with Dot Duncan hitting Stephen with her handbag.
After the Herrick party surrenders their seats to the Duncans, Dot realizes that her brother Pigeon found Stephen's lost tickets, and the embarrassed Duncans flee the theater.
The next day, at the offices of Herrick and Martin, Stephen is introduced to his new secretary, Dot Duncan. Recognizing Dot as his assailant from the previous evening, he dismisses her, but after she explains the confusion over the tickets, Stephen relents.
Soon after, Dot's beau, wrestler Claudius J. "Coffee Cup" Cup, returns from the Navy, promising to settle down and not re-enlist. While Dot and Coffee Cup are strolling down the street one day, Coffee Cup spots his pal Eddie, who he boasts, can grow four inches just by stretching. Eddie's aptitude for elongation draws a crowd, and soon Coffee Cup is taking bets from the skeptical onlookers. Stephen is drawn into the group when Dot borrows five dollars from him, and when the contest ends in a brawl in which Stephen is knocked unconscious, Coffee Cup takes him to the Duncan house to recover. Stephen awakens to the chaos of the Duncan household as Coffee Cup practices his wrestling technique on Pigeon, Mrs. Duncan delivers a neighbor's baby and Ivory, a sailor, tinkles the piano keys. Stephen is so delighted by Dot's boisterous family and friends that he accompanies her and Coffee Cup to a dance hall and congas the night away, forgetting all about his date with the snobbish Cecilia.

A: Who finds the shipping magnate's opera tickets?

Q: Passage: In its natural state, the Colorado River poured about 16.3 million acre feet (20.1 km3) into the Gulf of California each year, amounting to an average flow rate of 22,500 cubic feet per second (640 m3/s). Its flow regime was not at all steady – indeed, "prior to the construction of federal dams and reservoirs, the Colorado was a river of extremes like no other in the United States." Once, the river reached peaks of more than 100,000 cubic feet per second (2,800 m3/s) in the summer and low flows of less than 2,500 cubic feet per second (71 m3/s) in the winter annually.  At Topock, Arizona, about 300 miles (480 km) upstream from the Gulf, a maximum historical discharge of 384,000 cubic feet per second (10,900 m3/s) was recorded in 1884 and a minimum of 422 cubic feet per second (11.9 m3/s) was recorded in 1935. In contrast, the regulated discharge rates on the lower Colorado River below Hoover Dam rarely exceed 35,000 cubic feet per second (990 m3/s) or drop below 4,000 cubic feet per second (110 m3/s). Annual runoff volume has ranged from a high of 22.2 million acre feet (27.4 km3) in 1984 to a low of 3.8 million acre feet (4.7 km3) in 2002, although in most years only a small portion of this flow, if any, reaches the Gulf.
The United States Geological Survey (USGS) operates or has operated 46 stream gauges to measure the discharge of the Colorado River, ranging from the headwaters near Grand Lake to the Mexico–U.S. border. The tables at right list data associated with eight of these gauges. River flows as gauged at Lee's Ferry, Arizona, about halfway along the length of the Colorado and 16 miles (26 km) below Glen Canyon Dam, are used to determine water allocations in the Colorado River basin. The average discharge recorded there was approximately 14,800 cubic feet per second (420 m3/s), 10.72 million acre feet (13.22 km3) per year, from 1921 to 2010. This figure has been heavily affected by upstream diversions and reservoir evaporation, especially after the completion of the Colorado River Storage Project in the 1970s. Prior to the completion of Glen Canyon Dam in 1964, the average discharge recorded between 1912 and 1962 was 17,850 cubic feet per second (505 m3/s), 12.93 million acre feet (15.95 km3) per year.
