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.
Q: Passage: Sherman 'Tank' Turner is a help line operator and a ladies man with a hobby: If a guy loses a girl and wants her back, he gets in touch with Tank and pays him to take the girl on a bad date.  Throughout the evening Tank inevitably behaves in the most moronic fashion causing the girl to realize that her ex was not really such a bad guy after all and get back to their ex.
He shares an apartment with his step cousin Dustin who has fallen for his colleague Alexis. Dustin takes Alexis on a date and confesses his love but she insists they remain friends. After the date Dustin explains his situation to Tank who volunteers his services as a good friend (instead of having to pay for his services as usual). Dustin initially turns him down, not wanting Tank to be close to Alexis, but the next day sees Alexis flirting with another co-worker and begs Tank to take Alexis out. He accepts.
Tank bumps into Alexis and they arrange to go out.  He behaves badly all night but Alexis is too drunk to care. When he drops her off she expects him to come in but he resists the temptation out of loyalty to Dustin. Alexis calls Dustin but when they meet she explains that her date with Tank has motivated her to see other men.  Dustin sends Alexis roses and an apology poem in Tank's name. Alexis calls Tank at work and berates him for leaving early the previous night.  Tank goes to see Alexis and they end up having casual sex on a regular basis while Dustin begins a series of desperate attempts to stay friends with her after all.
A:
