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: Biker Queen, twin sister of Harley Mom, discovers the severed arm of her sister from the previous film. Upon discovering the surviving Bartender, she tortures him into telling her who killed Harley Mom. He reveals that it was Bozo and points her to a town where he lives. She knocks Bartender out and takes him with her to the town.
Prior to the events of the first film, the town was overrun by the monsters. A pair of small Mexican wrestlers named Thunder and Lightning were attacked by the monsters and Lightning's girlfriend was killed. Inside the jail, a "Hobo" was in a cell for dealing methamphetamine and questioned where his school bus (makeshift meth lab) is at. The Sheriff taunted him before being killed. A car salesman named Slasher found evidence of his wife cheating with one of his employees and barely escaped the monsters.
Biker Queen and four of her friends arrive in the deserted town with the Bartender, ignoring the dead bodies as they look for Bozo and cross paths with Slasher, his wife Secrets and the man she has an affair with, Greg. The group is attacked by a monster, which kills one of the biker girls, Tot Girl. The others and the Bartender make their way to Bozo's apartment, where they encounter Honey Pie, the girl who left the group from the first movie behind at the bar. Bartender brutally attacks her and knocks Honey Pie out of the window and onto the street. Honey Pie survives the fall and goes into hiding.
Slasher, Greg and Secrets receive a call from the wrestlers, but before they find them they are ambushed by the bikers. Both groups get to a garage where the brothers and their grandmother are hiding. The group then tries to make it to the jail, but the hobo has sealed himself in.
Solution:
What are the names of the two people who are twin sisters?
