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: Fred goes into music class to find his favorite teacher, Mrs. Felson, has been replaced by a teacher named Mr. Devlin. Walking home from school, Fred notices a strange girl named Talia following him. Fred believes he is being stalked, but the girl just walks the same way to school as him. Spying on Devlin that night, Fred sees him burying something, which he suspects is the body of Mrs. Felson. Kevin's mother invites Fred and his mother to a party for Mr. Devlin. At the party, Fred's mother falls in love with Mr. Devlin, and Fred learns that Talia is actually Kevin's sister.
The next day, Fred becomes extremely suspicious of Devlin and reaches the conclusion that he is a vampire. Mr. Devlin takes Fred's mother on a date, so Fred enlists his friend Bertha to spy on them. At a restaurant, Fred and Bertha learn that Mr. Devlin doesn't like garlic on his fries, making them all the more suspicious. Later that night, Fred's imaginary Dad brings him to a wrestling arena, where they tag team against Mr. Devlin and Kevin.
Fred is horrified at school the following day to discover Mr. Devlin running a blood drive at school. He's even more worried to discover Bertha taking personal music lessons from Devlin. Fred gathers items to use as weapons against Devlin, planning to defeat him at the school piano recital. Fred arms himself with him various tools and goes on a shooting spree of garlic sauce at the recital, soaking everyone except Devlin.
Solution: Who's favorite teacher is replaced?
