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.
Problem:Passage: Maria and Paul, a couple in their forties, travel through Spain with a new friend, Claire, a younger woman. The couple's daughter is also part of the trip. On their way to Madrid, they stop in a small town and are told by police that a local man who has killed his wife and her lover is on the loose in the area. There is a massive thunderstorm and the group has no choice but to stay in the town's only hotel, which is jammed beyond capacity with other travelers in the same situation. Maria, an out of control alcoholic who lives most of her life in a walking, booze-fueled dream state, seems to be subtly encouraging her husband Paul to have a sexual relationship with Claire as a way to reintroduce sexuality into their situation. While the thunderstorm is still raging, Maria secretly steps out of the crowded hotel onto a low balcony to down a bottle of booze and accidentally sees Paul and Claire kissing on a higher balcony. She is simultaneously excited and devastated.  While out in the rain Maria discovers the fugitive hiding on a nearby rooftop and decides to help him escape. She then hides the murderer, a young man, in an outcropping of rocks out in lonely stretch of highway in the desert.
