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.
One 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.
Solution is here: Who believes Fagin's gang make wallets and handkerchiefs?.
Explanation: 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.

Now, solve this: Passage: Charismatic roving peddler Hank Martin falls in love at first sight with schoolteacher Verity Wade and soon marries her. On their wedding day, he rents a ramshackle home from his upper class lawyer friend Jules Bolduc. Hank rounds up some of his many friends to fix up the place, but Verity begins to realize that he is not as nice as he appears to be; while they do the work, he sees nothing wrong in going inside to read a law book. He confides to her that it is all a matter of manipulating people the right way.
Jules invites the couple to dine with him that night, but Hank soon quarrels with another guest, Robert L. Castleberry IV. He accuses Castleberry, the owner of the company that buys cotton, of shortchanging the poor farmers.
When Hank goes about his business, Verity accompanies him to the bayou. A young woman named Flamingo leaps into his arms, but when she learns that he is now married, she tries to arrange for an alligator to rid her of her rival. Verity is only injured.  However, Flamingo does not give up on the man she has loved since she was a teen. After Hank sends Verity home to recover, Flamingo tracks Hank down on the road. She overcomes his resistance, and they start an affair.
Hank sets out to prove that Castleberry is cheating. When Hank proves that the weights used are seriously inaccurate, one of Castleberry's men aims a rifle at one of Hank's followers, and is killed by farmer Jeb Brown.
Solution:
What is the full name of the man that accuses the owner of the cotton buying company of shortchanging farmers?
