You will be given a definition of a task first, then some input 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: The film presents itself as an off-air recording of television station WNUF's Halloween special that aired on October 31, 1987. The movie's main plot centers upon Frank Stewart, a television reporter that has decided to broadcast himself live as he and four other people (including the cameraman) investigate the Webber House, the site of the brutal murder of a husband and wife. Donald Webber, the suspected murderer and the couple's son, claims that he was commanded to murder his parents by demonic entities that he accidentally summoned using a Ouija board. Since that day, the house has been reported to be haunted and an anonymous police officer testifies that he and other fellow police officers have witnessed paranormal activity at the house. Frank initially treats the broadcast as a novelty, even going so far as to dismiss the concerns of paranormal investigators Louis and Claire Berger (Brian St. August and Helenmary Ball), as Claire immediately states that the house contains a menacing presence and that they are in danger as long as they are in the house. He tries to dissuade fears by bringing in Father Joseph Matheson, who Frank claims is versed in Catholic exorcism rites, despite the priest's assertion that he only has a perfunctory knowledge of the rites and has never actually performed an exorcism.
Output:
What is the full name of the person who is the television reporter that brings in a priest versed in Catholic exorcism rites?
