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 action is set in San Francisco during the 1980s. Weslake, who was laid off from his job, is working in a low-paying position at Garvey's pawn shop. Weslake has one friend nicknamed 'Turtle' who's homeless and is seen throughout the whole film searching for something to eat.
One day, Dillard, who is an amateur musician, and Ramon, an illegal immigrant from Mexico who lives with his sister Maria, come to Garvey's shop. The purpose of their visit is to buy off a guitar pawned earlier by Dillard; because both have little money they're offering the pawn shop owner a stolen car radio, but it's not enough for Garvey. Instead, he offers Dillard a deal: he wants Dillard to install an alarm system in his shop (as Dillard is an electrician). Dillard is not thrilled by the deal but Ramon convinces him, arguing that when the alarm system is installed, Garvey may have enough confidence to leave the shop (he normally stays in it, since he lives there) and they may then get an opportunity to break in and get the guitar back.
Their conversation is heard by a 'Boardwalk', a pimp who was just left by his girlfriend with his small child. He tells Weslake that he should report the plans of Dillard and Ramon to Garvey, but Weslake realizes that when the new alarm system is installed, Garvey may no longer find it necessary to employ him, and he will be broke again. Because of this Weslake doesn't inform his employer of the planned robbery, and instead joins Dillard, Ramon Boardwalk and Turtle in their attempted robbery. He becomes the brain of the whole operation, designing a plan for breaking into the large safe in the pawn shop.
Output:
Who comes to the pawn shop to buy a guitar?
