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.
Q: Passage: Small-time Boston crook Tony Pino tries to make a name for himself. He and his five associates pull off a robbery whenever they can. Tony and his gang easily rob over $100,000 in cash from a Brink's armored car, after which Tony disguises himself as a sparkplug salesman to get an inside look at Brink's large and so-called "impregnable fortress" headquarters in the city's North End, a company renowned for unbreachable security as a private "bank" throughout the East Coast.
Once inside, Tony realizes that Brink's is anything but a fortress and that employees treat the money "like garbage." Still wary of Brink's public image, Tony breaks in one night after casing the building. He finds that only two doors in the building are locked, and one is easily bypassed by leaping a gate. The only thing locked in the building is the vault.
Tony also realizes that despite what Brink's claims, there is only a 10-cent alarm in the vault room itself, almost impossible to set off. It appears that Brink's had relied so much on its reputation that it had not even bothered locking the doors. Pino begins to plan a robbery, using the rooftop of a neighboring building as a watch tower.
Tony and his dim brother-in-law Vinnie put together a motley gang of thieves. They include the debonair Jazz Maffie and a slightly deranged Iwo Jima veteran, Specs O'Keefe, who proposes to blow open the Brink's safe with a bazooka. Over the crew's objections, Pino also invites the arrogant fence Joe McGinnis to be in on the job.
