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.

Let me give you an example: 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.
The answer to this example can be: Who believes Fagin's gang make wallets and handkerchiefs?.
Here is why: 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.

OK. solve this:
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.
Answer:
Who are the four people who travel through Spain?
