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.
Q: Passage: Madison "Maddie" Young is a deaf-mute woman who temporarily lost her ability to hear and speak after a bout of bacterial meningitis at the age of 13 and lost both permanently after a corrective surgery gone wrong. She lives in a house, isolated in the woods with her cat. Her friend and neighbor Sarah visits her one day to return a copy of her book. In discussing Maddie's writing, she describes with excitement how her stories play out in her head like a film and she can see all the possible endings. That night, a masked killer chases Sarah to Maddie's house. A bloodied Sarah bangs on the door begging and shouting for help, but Maddie cannot hear her, and the man stabs her to death.
The man quickly learns of Maddie's infirmity and sneaks into the house through the main door, steals her phone, takes photos of her and sends them to her. Realizing this, she locks herself inside the house. The man cuts the power and sabotages her car. Maddie writes on the glass-paneled front door "won't tell, didn't see face, boyfriend coming home" with her lipstick. However, the man responds by taking off his mask and showing off his face. Maddie unsuccessfully tries to distract him with her car alarm to get Sarah's phone from her body, but she manages to stab his arm with a hammer's claw. He mocks Maddie, revealing he has the phone as well. He takes one of Sarah's earrings out and puts it in his pocket.
A:
What is the last name of the person whose house Sarah is chased to?
