[Q]: Passage: A musician named Dixie Dwyer begins working with mobsters to advance his career but falls in love with the girlfriend of gangland kingpin Dutch Schultz.
A dancer from Dixie's neighborhood, Sandman Williams, is hired with his brother by the Cotton Club, a jazz club where most of the performers are black and the customers white. Owney Madden, a mobster, owns the club and runs it with his right-hand man, Frenchy.
Dixie becomes a Hollywood film star, thanks to the help of Madden and the mob but angering Schultz. He also continues to see Schultz's moll, Vera Cicero, whose new nightclub has been financed by the jealous gangster.
In the meantime, Dixie's ambitious younger brother Vincent becomes a gangster in Schultz's mob and eventually a public enemy, holding Frenchy as a hostage.
Sandman alienates his brother Clay at the Cotton Club by agreeing to perform a solo number there. While the club's management interferes with Sandman's romantic interest in Lila, a singer, its cruel treatment of the performers leads to an intervention by Harlem criminal "Bumpy" Rhodes on their behalf.
Dutch Schultz is violently dealt with by Madden's men while Dixie and Sandman perform on the Cotton Club's stage. 
Question: How does the dancer know Clay?
[A]: his brother.


[Q]: Passage: Hotshot ensign Alan Drake, fresh from the flying academy at Pensacola, Florida, gets off to a bad start with the pilots of an elite squadron, nicknamed the "Hellcats", to which he has been posted in San Diego. Making a nearly disastrous landing attempt in heavy fog against orders and disqualifying the squadron during a competitive shooting exercise by colliding with the target drogue does not endear him to his fellow pilots. He also asks out a woman he has met, Lorna, not knowing that she is the squadron commander Billy Gary's (Walter Pidgeon) wife.
However, Drake is earnest and contrite. He mixes with the Hellcats at the Garys' large house, which the sociable couple have opened as an unofficial officers' club. His flying and his social errors are forgiven, and his fellow pilots accept him, nicknaming him "Pensacola". 
Drake further proves himself when he helps Lieutenant Jerry Banning solve a problem in a blind-landing apparatus he is developing. Just after Commander Gary is sent out of town on assignment, Banning decides the apparatus is ready to test in fog — but it fails and Banning is killed. Working with Banning's assistant, Drake soon identifies the problem, but no further testing is allowed until Commander Gary's return.
Banning had been a childhood friend of Lorna Gary, and is not her first friend to die. She sinks into a deep depression. She also knows that Gary will expect her to hide her feelings and carry on, something that is very much not in her nature. Drake, appreciating the help the Garys gave him when he arrived, visits her at her home, and convinces her she should not suffer alone. They go for walks, drives, and tennis; he amuses her with jokes. Finally, at a restaurant she reaches for his hand and in doing so realizes she is falling for him. She quickly breaks away, and says she cannot see him any more. 
Question: What is the last name of the person that Lorna realizes that she can't see anymore?
[A]: Drake.


[Q]: Passage: Louis Salinger, an Interpol detective, and Eleanor Whitman, an Assistant District Attorney from Manhattan, are investigating the International Bank of Business and Credit, which funds activities such as money laundering, terrorism, arms trading, and the destabilization of governments. Salinger's and Whitman's investigation takes them from Berlin to Milan, where the IBBC assassinates Umberto Calvini, an arms manufacturer who is an Italian prime ministerial candidate. The bank's assassin diverts suspicion to a local assassin with political connections, who is promptly killed by a corrupt policeman. Salinger and Whitman get a lead on the second assassin, but the corrupt policeman shows up again and orders them out of the country. At the airport they are able to check the security camera footage for clues on the whereabouts on the bank's assassin, and follow a suspect to New York City.
In New York, Salinger and Whitman are met by two New York Police Department detectives, Iggy Ornelas and Bernie Ward, who have a photograph of the assassin's face when he arrived in New York airport. Salinger, Ornelas, and Ward locate Dr. Isaacson to whose practice the assassin's leg brace has been traced. They find the assassin and follow him to the Solomon R. Guggenheim Museum.
Jonas Skarssen, the chairman of the IBBC, reveals to his senior men White and Wexler that the bank had Calvini killed so that they could deal with his sons to buy missile guidance systems in which the bank has invested. Since the bank knows that Salinger and Whitman are close to finding their assassin, they send a hit team to kill him at a meeting between him and his handler, Wexler. Wexler leaves and is arrested by Ornelas. As Salinger speaks to the assassin, a shootout at the Guggenheim erupts when a number of gunmen attempt to kill them with automatic weapons. They escape, but the assassin is mortally wounded. 
Question: What are the first names of the people who locate Dr. Isaacson?
[A]:
Louis.
