question:
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.
answer:
Who finds the shipping magnate's opera tickets?


question:
Passage: The management of Rockefeller Center shifted around this time. In November 1936, John Todd was featured in two New Yorker articles that emphasized his role in the complex's construction. At the same time, Nelson was gaining clout within Rockefeller Center Inc., and he disagreed with nearly all of Todd's suggestions. Nelson's father, John, was relinquishing his responsibilities, since the Rockefeller family's youngest son David had moved out of the family home at 10 West 54th Street, and John was now focusing on his own personal life. By April 1937, Todd regretted his decision to be featured in The New Yorker. In March 1938, Nelson became the president of Rockefeller Center Inc. He then fired Todd as the complex's manager and appointed Hugh Robertson in his place. Nelson and Robertson wanted to avoid workers' strikes, which would delay the completion of construction. Nelson, Robertson, and the workers' unions agreed to a contract in which the unions would not strike, Robertson would not lock out union workers, and both would agree to arbitration if a labor dispute arose. Rockefeller Center was one of Nelson's primary business ventures until 1958, when he was elected Governor of New York.Public relations officials were hired to advertise the different parts of the complex, such as the gardens and the plaza. Merle Crowell set up a viewing platform on the east side of Rockefeller Center and founded the facetious "Sidewalk Superintendents' Club" so the public could view construction.
answer:
What is the first name of the person who appointed Hugh Robertson as the complex manager?


question:
Passage: The session, held the evening of July 5, proved entirely unfruitful until late in the night. As they were about to abort and go home, Presley took his guitar and launched into a 1946 blues number, Arthur Crudup's "That's All Right". Moore recalled, "All of a sudden, Elvis just started singing this song, jumping around and acting the fool, and then Bill picked up his bass, and he started acting the fool, too, and I started playing with them. Sam, I think, had the door to the control booth open ... he stuck his head out and said, 'What are you doing?' And we said, 'We don't know.' 'Well, back up,' he said, 'try to find a place to start, and do it again.'" Phillips quickly began taping; this was the sound he had been looking for. Three days later, popular Memphis DJ Dewey Phillips played "That's All Right" on his Red, Hot, and Blue show. Listeners began phoning in, eager to find out who the singer really was. The interest was such that Phillips played the record repeatedly during the remaining two hours of his show. Interviewing Presley on air, Phillips asked him what high school he attended in order to clarify his color for the many callers who had assumed that he was black. During the next few days, the trio recorded a bluegrass number, Bill Monroe's "Blue Moon of Kentucky", again in a distinctive style and employing a jury rigged echo effect that Sam Phillips dubbed "slapback". A single was pressed with "That's All Right" on the A side and "Blue Moon of Kentucky" on the reverse.
answer:

What was the name of the show listeners began phoning in eager to find out who the singer really was?
