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

Problem: Passage: The film follows a diverse group of mostly middle-class Los Angelenos through the emotional ups and downs in their flawed yet very human lives, each loosely connected to each other through a restaurant.
In the first story, Mamie reluctantly agrees to work with a would-be young filmmaker in order to locate the now grown son she secretly gave up for adoption after becoming pregnant from her stepbrother Charley – who is later revealed to be gay – 19 years earlier.
In the second story arc, her stepbrother, and his domestic partner, Gil, are deciding whether or not to confront their friends, a lesbian couple (Laura Dern and Sarah Clarke), regarding the paternity of their son.
And in the third, a young man, Otis, is involved with a band and trying to keep his father, Frank, from learning that he is gay, while also dealing with the seemingly gold-digging woman, Jude, who inserts herself into their lives.
Solution: Who is the gay man that fathered Mamie's son?
