[EX Q]: Passage: Travis Bickle, a 26-year-old honorably discharged U.S. Marine, is a lonely, depressed young man living in isolation in New York City. He takes a job as a taxi driver to cope with his chronic insomnia, driving passengers every night around the city's boroughs. He also frequents the porn theaters on 42nd Street and keeps a diary in which he consciously attempts to include aphorisms, such as "You're only as healthy as you feel."
Travis becomes infatuated with Betsy, a campaign volunteer for Senator and presidential candidate Charles Palantine. After watching her interact with fellow worker Tom through her window, Travis enters to volunteer, as a pretext to talk to her, and takes her out for coffee. On a later date, he naively takes her to see a pornographic film, which offends her, and she goes home alone. His attempts at reconciliation by sending flowers are rebuffed, so he berates her at the campaign office, before being kicked out by Tom.
Travis is disgusted by the sleaze, dysfunction, and prostitution that he witnesses throughout the city. His worldview is furthered when an adolescent prostitute and runaway, Iris, enters his taxi, attempting to escape her pimp, Sport. Sport drags Iris from the taxi and throws Travis a crumpled $20 bill, which continually reminds Travis of her and the corruption that surrounds him. A similarly influential event occurs when an unhinged passenger gloats to Travis of his intentions to murder his wife and her lover. Travis confides in fellow taxi driver Wizard about his thoughts, which are beginning to turn violent; however, Wizard assures him that he will be fine, leaving Travis to his own destructive path. 
Question: What is the last name of the person that is told he will be fine by Wizard?
[EX A]: Bickle.

[EX Q]: Passage: Johnny Clay is a veteran criminal planning one last heist before settling down and marrying Fay. He plans to steal $2 million from the money-counting room of a racetrack during a featured race. He assembles a team consisting of a corrupt cop, a betting window teller to gain access to the backroom, a sharpshooter to shoot the favorite horse during the race to distract the crowd, a wrestler to provide another distraction by provoking a fight at the track bar, and a track bartender.
George Peatty, the teller, tells his wife Sherry about the impending robbery. Sherry is bitter at George for not delivering on the promises of wealth he once made her, so George hopes telling her about the robbery will placate and impress her. Sherry does not believe him at first but, after learning that the robbery is real, enlists her lover Val Cannon to steal the money from George and his associates.
The heist is successful, although the sharpshooter is shot and killed by a security guard. The conspirators gather at the apartment where they are to meet Johnny and divide the money. Before Johnny arrives, Val appears and holds them up. A shootout ensues and a badly wounded George emerges as the only man standing. He goes home and shoots Sherry before collapsing.
Johnny, on his way to the apartment, sees George staggering in the street and knows that something is wrong. He buys the biggest suitcase he can find to put the money in (and struggles to lock it properly). At the airport Johnny and Fay are not allowed to take the case on their flight due to its size. Instead, they must check it as regular luggage. Johnny reluctantly complies. While waiting to board the plane the couple watch the suitcase fall off a baggage cart onto the runway, break open, and the loose banknotes scattered and then swept away by the backdraft from the aircraft's propellers. 
Question: What are the names of the couple who watch the suitcase fall off a baggage cart onto the runway and break open?
[EX A]: Johnny Clay.

[EX Q]: Passage: Frank Chambers a drifter, stops at a depression-era rural California diner for a meal and ends up working there. The diner is operated by a young, beautiful woman, Cora Smith, and her much older husband, Nick Papadakis, a hardworking but unimaginative immigrant from Greece.
Frank and Cora start to have an affair soon after they meet. Cora is tired of her situation, married to an older man she does not love, and working at a diner that she wishes to own and improve. She and Frank scheme to murder Nick to start a new life together without her losing the diner. Their first attempt at the murder is a failure, but Nick is not even aware they tried to kill him, so goes about living his life as usual. Frank and Cora succeed with their next attempt.
The local prosecutor suspects what has actually occurred but does not have enough evidence to prove it. As a tactic intended to get Cora and Frank to turn on one another, he tries only Cora for the crime.
Although they turn against each other, a clever ploy from Cora's lawyer, Katz, prevents Cora's full confession from coming into the hands of the prosecutor. With the tactic having failed to generate any new evidence for the prosecution, Cora benefits from a deal in which she pleads guilty to manslaughter and is sentenced to probation.
Months later, Frank has an affair with Madge Gorland while Cora is out of town. When Cora returns, she tells Frank she is pregnant. That night, Katz's assistant, Kennedy, appears at their door and threatens to expose them unless they give him $10,000. Enraged, Frank beats Kennedy up and strong-arms him into giving up the evidence against them. 
Question: What is the last name of the person who is hired by Cora and Nick?
[EX A]:
Chambers.
