Detailed Instructions: 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.
Problem:Passage: Mark (Doherty) is an actor living in a basement flat below his writer friend Pierce. Residing with his girlfriend, Sally, Mark struggles to find work whilst caring for his paralysed brother, David. Desperate to avoid paying overdue rent, Mark continually eludes landlord Jack, meaning he is also unable to inform Jack of the flat's dilapidated state.
Discovering that Mark wasted money meant for the overdue rent, Sally finally decides to end her strained relationship with Mark, informs Jack of the repairs needed, and arranges to move out. The damaged state of the flat reaching its peak, Mark witnesses two consecutive freak accidents; a bookshelf falls and kills his dog, and the living room chandelier collapses and crushes David. Reeling in horror from the events, Mark looks on as Jack appears to repair a high lightbulb atop a wobbly stool, only to fall and pierce his throat with his screwdriver. Pierce then arrives and discovers the corpses, causing him to panic.
Hiding in the bathroom, Mark and Pierce plot to control the situation, only for Sally to return. Discovering David's body, Sally faints and impales herself on Mark's clarinet stand, killing her too. Realizing the absurdity of four consecutive, fatal accidents occurring in one place, Pierce concocts a plan to move Jack's body to an alternative location, as they both had a strong motive to murder him. Shooing Sally's father when he arrives, a police officer then arrives due to an unrelated noise complaint, causing Pierce to panic and take her hostage.
Solution:
Who are killed by freak accidents?
