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: After a 20-year hiatus, divorcee Laura Le Crois is forced to return to her home in a wetland in Louisiana after her father Pappy goes missing along with several other locals to briefly take over his wetland tour business. There, she discovers that her ex-husband, zoologist Charles LeBlanc is attempting to buy the wetland for unknown reasons, and is looking for Pappy. After Laura drives him off, she is met by a man named Matt, who will be soon drafted into the Marines. Matt asks Laura to give him, and his girlfriend Mandy a tour of the wetland so he can propose to her later that evening. Laura reluctantly agrees, and the three head off on a small motorboat.
That evening, Matt proposes to Mandy, and she accepts as the group takes a break at a dock. Laura soon witnesses her father being thrown into the water by locals Barry, and Larry Boudreaux before getting eaten by a pilosaurus, an aquatic reptile thought to be extinct. As she runs back to warn Matt, and Mandy, she finds that Barry, and Larry have knocked Matt unconscious, and taken Mandy hostage before Laura herself is knocked unconscious by Larry.
The next morning, Laura, Matt, and Mandy are reported as missing, and Laura's ex-boyfriend, Sheriff Tim Richards, and his younger brother Deputy Henry are sent to investigate. After coming up short, Tim interrogates Charles as to why he's buying the wetland, although after getting little information, he instead decides to investigate the length of the wetlands along with local Froggy on a small motorboat in order to find Laura. Meanwhile, Laura, Matt, and Mandy are tied up in Barry, and Larry's cabin, which is lined with explosives. Barry, and Larry take out Matt to be fed to the pilosaurus while Henry encounters Charles after finding a jaw belonging to a large creature. Charles explains that the jaw belongs to the pilosaurus, and encourages Henry to investigate the disappearances himself.
