Given the task definition, example input & output, solve the new input case.
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.
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.
Output: Who believes Fagin's gang make wallets and handkerchiefs?.
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 case for you: Passage: Elizabeth Masterson, a young emergency medicine physician whose work is her whole life, is in a serious car accident while on her way to a blind date. Three months later, David Abbott, a landscape architect recovering from the sudden death of his wife, moves into the apartment that had been Elizabeth's, after 'discovering' it in what seems to be a fateful happenstance.
Elizabeth's spirit begins to appear to David in the apartment with ghostly properties and abilities that make it clear that something is not right. She can suddenly appear and disappear, walk or move through walls and objects, and once takes over his actions. When they meet, they are both surprised, as Elizabeth is still unaware of her recent history and refuses to think she is dead. David tries to have her spirit exorcised from the apartment, but to no avail. Since only David can see and hear her, others think that he is hallucinating and talking to himself.
David and Elizabeth begin to bond, as much as that is possible, and he takes her out of town to a beautiful landscaped garden he designed. Elizabeth tells him she senses she has been there before, and in fact, the garden was something she was dreaming of in the opening scenes of the film, where she was awakened by a colleague from cat-napping after working a 23-hour shift in the hospital.
Together, assisted by a psychic bookstore clerk, Darryl, Elizabeth and David find out who she is, what happened to her, and why they are connected. She is not dead, but in a coma, her body being kept on life support at the hospital where she used to work. When David discovers that in accordance with her living will, she will soon be allowed to die, he tries to prevent this by telling Elizabeth's sister, Abby, that he can see her and what the situation involves. One of Elizabeth's young nieces is revealed to be able to sense her presence as well.
Output:
What is the profession of the person that sees Elizabeth's spirit?
