Q: 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.
Passage: Young bachelors and best friends Fred Flintstone and Barney Rubble have recently qualified as crane operators at Slate & Company. Soon to be employed, now they want dates, and a little green alien The Great Gazoo, exiled to Earth by his species, offers to help, although only they can see him. Meanwhile, Wilma Slaghoople wants a normal life and activities, like bowling, despite her controlling mother Pearl, who wants her to marry smooth casino-owner Chip Rockefeller. Wilma angrily runs away to Bronto King in Bedrock. Waitress Betty O'Shale mistakes her as "caveless", and offers to share her apartment, and gets her a job.
Fred and Barney are smitten with the waitresses and invite them to a carnival, with Fred dating Betty and Barney taking Wilma. Fred wins a carnival game and gets a prize of an egg which hatches into a baby dinosaur, which he names "Dino". However, he does not really feel a connection with Betty, nor does Barney with Wilma, until both men switch dates. Wilma invites her new friends home to a birthday party for her father, Colonel Slaghoople, where all are shocked by her wealth. Fred intends to propose, but changes his mind after meeting Chip, who berates him for his low-level job at Slate & Company. Pearl dislikes the three new friends, but the Colonel accepts them, glad Wilma is happy, and privately gives her a valuable pearl necklace that once belonged to his great-grandmother. After the boys disgrace themselves at dinner, Wilma nevertheless proclaims her pride and follows them out.
