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 story is set in an alternate reality America circa 1985 under the authoritarian control of President Fremont. It makes liberal references to the collected works of Philip K. Dick.
Berkeley record store clerk Nick Brady lives modestly with his wife Rachel and their infant son. Nick has been experiencing strange visions and dreams. He confides in Rachel and his best friend, science-fiction writer Philip K. Dick. Nick calls the source of his visions VALIS.
One recurring symbol that he has been seeing is an ichthys. While he and Phil sit at a table, an orbiting satellite shoots a pink laser directly into Nick's head. He rushes his son to the ER, convinced that he has an inguinal hernia. The skeptical doctor is stunned to find that Nick is right. Nick has subsequent visions that tell him that he should relocate to Los Angeles, where he lands a job at a record label.
Philip gets visited by two members of FAP (Friends of the American People). They press him for information about Nick's visions. The female FAP agent returns and sleeps with Philip. After their liaison, she pretends to be underage, hoping to coerce him into revealing what Nick is seeing from VALIS. Philip refuses to divulge anything about Nick.
Meanwhile, Nick has a dream where a woman is singing. During the dream, someone comments that there is something about her singing that seems subversive. Eventually, the woman turns up at Nick's record label, looking for a clerical job. She introduces herself as Sylvia, and Nick just assumes that she is a singer. Sylvia gradually reveals that she also receives visions from VALIS. She explains that there are several thousand people who receive transmissions from the orbiting satellite, and they are very loosely organized as a secret society.
Solution:
What is the full name of the person that is seeing an ichthys?
