Q: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs. 
Question: Who believes Fagin's gang make wallets and handkerchiefs?
A: Oliver.
Rationale: In the sentence "He believes they make wallets and handkerchiefs", the pronoun "he" refers to name "Oliver".
Q: 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. 
Question: What is the last name of the person who threatens to yank a record company's discs out of jukeboxes everywhere?
A:
Pearl.
