You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

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.
Solution: Who believes Fagin's gang make wallets and handkerchiefs?.
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.

New input: Passage: Yale grad Dan Brooks is expected to marry wealthy boss J.L. Higgins' (Charles Bickford) daughter Margaret and join the family box-making business. He is far more interested in racing a horse he owns, Broadway Bill.
Doing poorly at work, Dan and his groom Whitey leave town to enter Bill in the Imperial Derby, but first must find money for the entry fee. He and old pal Professor Pettigrew each try to con the other out of a few bucks, then end up singing the Yale school song to get out of a restaurant tab they cannot pay.
Maggie's younger sister Alice is secretly in love with Dan, so she offers him some money, pawning her belongings. Whitey is beaten up trying to win some in a craps game, and Broadway Bill is carted away because Dan does not pay his feed bill. Dan is jailed, too.
A rich man makes a bet on 100-to-1 shot Bill, leading to false rumors that the horse is a shoo-in. The odds drop fast, but gamblers and a crooked jockey try to make sure their own favorites win the race. Broadway Bill somehow manages to win, but collapses at the finish line and suffers a fatal heart attack.
A saddened Dan takes comfort in deciding to buy and race Broadway Bill II. His enthusiasm persuades Alice and even her dad to lend Dan a hand.
Solution:
Who is Margaret's fathers name?
