Task: Question Generation
Input (English): Passage: Everything's going well at Disco Records, where singer Johnny Conroy is popular and publicity chief Marty Collins is good at her job, as well as in love with company boss Mack Adams.
Everything changes when Barney Pearl shows up. Pearl is a crude businessman who supplies records to jukeboxes coast-to-coast. He demands to be made a full partner in Disco Records or he will yank their discs out of jukes everywhere. Furthermore, he insists that singer girlfriend Mona De Luce gets to make a record of her own.
Implored not to agree, Mack goes along. Pearl keeps the pressure on, renaming the company after himself. Johnny quits and leaves on his sailboat for points unknown. Mona, meanwhile, is a much better singer than expected. Her record is a smash hit, annoying Barney, who wants her wholly dependent on him. Barney demands her career come to an end.
Marty, Mack and Mona all travel to the West Indies, where Johnny is now enjoying the sun, fun and music. Johnny suggests they begin recording calypso songs. It all works out perfectly, and when Pearl tries to cut himself in, they find a way to keep him out.
Output (English): What is the last name of the person who threatens to yank a record company's discs out of jukeboxes everywhere?
