Detailed Instructions: 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.
See one example below:
Problem: 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: 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.

Problem: Passage: Tom and Dan meet in a bar and then proceed to Tom's apartment together.  While there, Dan realizes that he had been in that same apartment before.  Five years earlier, Dan and Tom had a one night stand there.  According to Tom, that encounter with Dan was his first and only homosexual experience.  Some years later, Tom's wife is found to be HIV positive.  Despondent after receiving this diagnosis from her doctor, Tom's wife drives through a red traffic light and is killed in an ensuing collision.  Subsequent to these events, medical tests reveal that Tom is also HIV positive.  Tom blames himself for passing HIV on to his wife and, in turn, he blames Dan for passing the virus on to him.  Reasoning that Dan, ultimately, is to blame for his wife's death, Tom devises a plan to exact revenge.  He holds Dan hostage, keeping him bound and gagged to a chair in his apartment. He draws blood from Dan in order to conduct a test to determine Dan's HIV status.  If Dan's test results are positive for HIV, Tom vows to kill Dan.  If the results are negative, Tom agrees to release Dan unharmed. In the end, Tom returns to the apartment and lets Dan go. As Dan is leaving, Tom asks him when he had last been tested. A few moments later, he reveals that Dan's test was, in fact, positive. He decided to let Dan go because he realized that his positive status was the result of his choices which he couldn't blame on anyone else. The screen fades with Dan standing in Tom's doorway in shock.
Solution:
What is the name of the person Tom blames in the end for his HIV status?
