In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Example Input: 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?
Example Output: his brother.

Example Input: Passage: To design and build his ship Nansen chose Colin Archer, Norway's leading shipbuilder and naval architect. Archer was well known for a particular hull design that combined seaworthiness with a shallow draught, and had pioneered the design of "double-ended" craft in which the conventional stern was replaced by a point, increasing manoeuvrability.  Nansen records that Archer made "plan after plan of the projected ship; one model after another was prepared and abandoned". Finally, agreement was reached on a design, and on 9 June 1891 the two men signed the contract.Nansen wanted the ship in one year; he was eager to get away before anyone else could adopt his ideas and forestall him.  The ship's most significant external feature was the roundness of the hull, designed so that there was nothing upon which the ice could get a grip. Bow, stern and keel were rounded off, and the sides smoothed so that, in Nansen's words, the vessel would "slip like an eel out of the embraces of the ice".  To give exceptional strength the hull was sheathed in South American greenheart, the hardest timber available. The three layers of wood forming the hull provided a combined thickness of between 24 and 28 inches (60–70 cm), increasing to around 48 inches (1.25 metres) at the bow, which was further protected by a protruding iron stem. Added strength was provided by crossbeams and braces throughout the length of the hull.
The ship was rigged as a three-masted schooner, with a total sail area of 6,000 square feet (560 m2). Its auxiliary engine of 220 horse-power was capable of speeds up to 7 knots (13 km/h; 8.1 mph). However, speed and sailing qualities were secondary to the requirement of providing a safe and warm stronghold for Nansen and his crew during a drift that might extend for several years, so particular attention was paid to the insulation of the living quarters. At around 400 gross register tonnage, the ship was considerably larger than Nansen had first anticipated, with an overall length of 128 feet (39 m) and a breadth of 36 feet (11 m), a ratio of just over three to one, giving her an unusually stubby appearance. This odd shape was explained by Archer: "A ship that is built with exclusive regard to its suitability for [Nansen's] object must differ essentially from any known vessel." On 6 October 1892, at Archer's yard at Larvik, the ship was launched by Nansen's wife Eva after a brief ceremony. The ship was named Fram, meaning "Forward". 
Question: What is the name of the ship that was rigged as a three-masted schooner, with a total sail area of 6,000 square feet?
Example Output: Fram.

Example Input: Passage: During the rage of Hurricane Katrina, Detective Andy Devereaux discovers the body of his former partner in a close to underwater warehouse. Quickly forgetting about his discovery, he joins a newly transferred detective named Stan Johnson (Curtis "50 Cent" Jackson) trying to end a conflict involving looters. 
Post-Katrina, Andy and Stan are now partners. They work with corrupt detectives Pepe and Barney, who are caught up in the murder of an undercover narcotics agent. Investigating the escalating police corruption in New Orleans is FBI Agent Brown. Brown brings up his thoughts to Police Captain Friendly who insists he is doing his best to solve the problems in his department.
Meanwhile, police therapist Nina Ferraro tries to help the detectives with their struggles, with little avail. She is particularly interested in Andy, whose father, also a detective, was murdered in the line of duty. 
Things are complicated further with Agent Brown's investigation into Andy and his crew. Brown tells Andy that he has an informant who is leaking out the details, and Andy, disbelieving at first, begins to resign himself to the fact that one of his men is betraying him. 
After Captain Friendly is assassinated by a local gangster named Chamorro, Andy, Stan, Pepe, and Barney decide to take the law into their own hands and go after Chamorro. While interrogating Chamorro, they find out that Brown has been supplying the drug dealer with information about the police raids, to help his own investigation. In a violent shootout, Barney accidentally shoots and kills Pepe.
Andy and Stan escape, only to return to the warehouse where they met. There Andy realizes that Stan is the informant. After the two start arguing, Brown shows up and there is another shootout, ending in Brown's death. Andy comforts a sobbing Stan, then Andy kills his partner, as he possibly did with his previous one. 
Question: What is the last name of the person that Andy kills?
Example Output:
Johnson.
