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: In 1947, Humbert Humbert, a middle-aged European professor of French literature, travels to the United States to take a teaching position in New Hampshire. He rents a room in the home of widow Charlotte Haze, largely because he is romantically attracted to her adolescent daughter Dolores, also called "Lo", who he sees while touring the house. Obsessed from boyhood with girls of approximately her age (whom he calls "nymphets"), Humbert is immediately smitten with Lo and gets married to Charlotte only just to be near her daughter.
Charlotte finds Humbert's secret diary and discovers his preference for her daughter. Furious, Charlotte runs out of the house, when she is struck by a car and killed.  Her death frees Humbert to pursue a romantic and sexual relationship with Lo, whom he nicknames "Lolita". Humbert and Lo then travel the country, staying in various motels before eventually settling in the college town of Beardsley, where Humbert takes a teaching job and Lo begins attending an all-girls Catholic school. However, Lo's increasing boredom with Humbert, combined with her growing desire for independence, fuels a constant tension that lead to a fight between them. Humbert's affection for Lo is also rivaled by another man, playwright Clare Quilty, who has been pursuing Lo since the beginning of the pair's travels. Lo eventually escapes with Quilty, and Humbert's search for them is unsuccessful, especially as he doesn't know Quilty's name.
Three years later, Humbert receives a letter from Lo asking for money. Humbert visits Lo, who is now married and pregnant. Humbert asks her to run away with him, but she refuses. He relents and gives her a substantial amount of money. Lo also reveals to Humbert how Quilty actually tracked young girls and took them to Pavor Manor, his home in Parkington, to exploit them for child pornography. Quilty abandoned her after she refused to be in one of his films.
Answer:
What is the full name of the mother of the girl that the professor of French Literature is attracted to?
