You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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: 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.
Solution: Who believes Fagin's gang make wallets and handkerchiefs?.
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.

New input: Passage: The film begins by introducing Kellyanne Williamson, playing with imaginary friends Pobby and Dingan. The family of Rex Williamson—his wife, Anne, daughter Kellyanne and son Ashmol—have moved to Coober Pedy, known as the "opal capital of Australia", because Rex believed he could make a fortune in mining opal. So far he's had little success. Ashmol, while he loves his sister, is frequently annoyed when she talks to her imaginary friends, and some of the kids at school tease the siblings because of them.
Rex and Anne decide it is time to separate Kellyanne from her invisible companions. Annie takes Kellyanne to a Christmas party at Annie's friend's house, Rex telling her that he will let Pobby and Dingan come with him to go opal mining. Upon Rex's return, Kellyanne says she can no longer see them and that they have disappeared. She insists on going to the opal mining area to look for them, accompanied by Rex and Ashmol. The family accidentally strays on to a neighbouring miner's claim. The miner, Sid, pulls a shotgun on Rex and calls the police, thinking that Rex was "ratting" on his territory - that is, looking for opals on his turf.
Kellyanne is grief-stricken at the loss of her imaginary friends and takes ill, although doctors can find nothing physically wrong with her. Rex has to leave his opal claim. Annie loses her job at the local supermarket, thanks to the circulating rumours around Rex's arrest. Convinced that Kellyanne is faking her illness, Ashmol nonetheless goes along with her wish that he try to find Pobby and Dingan. He even comes up with the idea of putting posters around town. Ultimately, returning to his father's mine area, Ashmol finds two lollipop wrappers. Deeper in the tunnel, he finds a large opal which he takes back to Kellyanne. He tells her he has found Pobby and Dingan, and that they are dead.
Solution:
What are the first names of Kellyanne's parents?
