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.

Let me give you an example: 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.
The answer to this example can be: Who believes Fagin's gang make wallets and handkerchiefs?.
Here is why: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

OK. solve this:
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.
Answer:
What is the last name of the person who demands to be made a full partner?
