Teacher: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.
Teacher: Now, understand the problem? Solve this instance: Passage: NYPD officer Charlie Lang is a kind and generous man who loves his job in Queens, New York, where he lives. His wife, Muriel, works at a hair salon and, unlike him, is greedy, materialistic, and selfish, constantly complaining about their situation in life. Waitress Yvonne Biasi is bankrupt because her husband, Eddie, whom she could not yet afford to divorce, emptied their joint checking account without her permission, while also leaving her with over $12,000 in credit card debt. Charlie meets her when she waits on him at the diner where she works. Since he doesn't have enough money to pay the tip, he promises to give her either double the tip or half of his prospective lottery winnings the next day using a ticket which has numbers he regularly plays. He wins $4 million ($6.8 million today) in the lottery the next day and keeps his promise, despite Muriel's protests.
He and Yvonne become stars almost immediately. She buys the diner and sets up a table with his name at which people who can't afford a meal can eat for free. In another development, he becomes a hero for foiling an attempted robbery at a grocery store but gets wounded in the process, forcing him to take a leave of absence from the police force. Meanwhile, Muriel goes on a shopping spree, and also contracts for disruptive renovations to their apartment without consulting him.
