Part 1. Definition
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.
Part 2. 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.
Answer: 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.
Part 3. Exercise
Passage: From her Parkville jail cell, Vergie Winters watches the funeral procession of Senator John Shadwell and remembers her twenty-year past with him: The moment young lawyer John returns to Parkville from an extended honeymoon with his social climbing wife Laura, he visits Vergie, his former lover. After a passionate embrace, John explains to the youthful milliner that he had abandoned their romance because Vergie's father had told him that she was pregnant by laborer Hugo McQueen and would be forced to marry. Vergie then tells John that, to keep her from marrying John, Laura's father had paid her father $10,000 to tell him that devastating lie.
Still deeply in love, John and Vergie continue to see each other, but when John starts to campaign for Congress, Preston, a political boss, informs Vergie that, if John is to receive his vital support, she must forego their affair. Although Vergie agrees to Preston's terms, John refuses to end the relationship and spends a long evening with her before the election. 
After a victorious win, John moves to Washington, D.C. with Laura, Vergie bears his child under an assumed name. John then adopts the baby, named Joan, whom he claims is the child of a destitute family friend. 
At the start of World War I, John returns to Parkville and once again resumes his affair with Vergie. When one of John's late night rendezvous is witnessed by a town gossip and reported to Mike Davey, John's only political enemy, Vergie's successful millinery shop is boycotted, and she is shunned by all but the local prostitutes. In addition, Davey hires Preston's son Barry to steal from Preston's home safe a page from a hotel register on which Vergie had written her assumed name. As Barry is breaking into his father's safe, however, Preston mistakes him for a burglar and kills him, but tells his butler that a burglar shot his son.
Answer:
What is the full name of the person who visits their former lover?
