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: Mammy Two Shoes is preparing a fancy dinner, with both Tom and Jerry observing. Jerry starts eating the cracker spread, but Tom knocks Jerry out by whacking him with a spoon and calls Toots, his love interest, to invite her to dinner. Jerry is forced to perform menial duties for the cats, such as carrying food and blowing on Tom's soup. Annoyed, Jerry drinks the soup and spits it into Tom's face, causing Tom to put the spoon Jerry is standing on over a burning candle to make him hop on both feet and yelp in pain.
As Toots offers Tom bread, Jerry sandwiches Tom's tail between it. Unaware, Tom pours ketchup onto it and bites it, causing him to leap up in pain. Tom is then unaware again, trying to stay cool for his date, as Jerry puts a pineapple slice, cream and cherry onto it, and Tom leaps up after biting it again. Tom grabs Jerry and twists his tail into a champagne-cork opener to make two drinks, launching Jerry into a glass of water.
Tom then tries to hug and kiss his girlfriend, but Toots impressively dodges each attempt. When Tom finally hugs Toots, she takes out a "wolf pacifier" (a mallet) and wallops him with it. As Jerry mocks Tom, Tom puts a cigar into Jerry's mouth, whacks him and lights a cigar onto him, causing Jerry to launch a pie into Tom's face. Tom throws a pie in return, but Jerry ducks and the pie hits Toots, effectively ending the relationship between the two cats. 
Question: What are the names of the cats who had a relationship?
Example Output: Jerry.

Example Input: Passage: Eleven year old Randy Daytona becomes anxious when he learns that his father Peter has bet on his performance in the 1988 Summer Olympics table tennis finals. During his first game between his opponent Karl Wolfschtagg from the German Democratic Republic, Daytona has an accident and suffers an injury. Unable to continue, he loses the match. Loan sharks, in the employ of criminal mastermind Feng, murder his father, and Daytona leaves competitive ping-pong.
Nineteen years later, Daytona is dismissed from the Peppermill casino and meets FBI agent Ernie Rodriguez, who requests his assistance in arresting Feng for running guns. Feng's hidden jungle hideout hosts a black-market Ping-Pong tournament, and Daytona's invitation is a way for the FBI to infiltrate Feng's organization. When Daytona agrees, Rodriguez tells him to win enough championships that Feng's scouts notice him. After losing a local tournament, Daytona is apprenticed to a blind man in Chinatown named Wong, who was Feng's former mentor. Daytona also meets Wong's niece, Maggie. When locals vandalize Master Wong's house for violating their edict against teaching white people ping pong, Daytona is forced to play against "The Dragon", a young girl, in exchange for Wong's right to stay. After Daytona beats the Dragon, Feng's men take notice of his win and bring Daytona, Rodriguez, and Wong to Feng's facility. 
Question: Who do the loan sharks that work for the criminal mastermind kill?
Example Output: Peter.

Example Input: Passage: During the 1930s, the Navy contracted a $1.5 million dredging of Pearl Harbor to allow larger battleships and the fleet's carriers to enter it. Work began in May 1940 resulting in 13,000,000 cubic yards (9,900,000 m3) of material dredged from the opening of Pearl Harbor to build a channel to Ford Island as well as to create a turning channel around the island.  Material was also dredged to deepen the West Loch, East Loch, and Middle Loch for the mooring of battleships. With dredged material used as land fill, the island's size was increased from 334 acres (135 ha) to 441 acres (178 ha).The Navy replaced its PK, F5L, and H16 aircraft with newer models (see table below). In 1933 VP-8F arrived on station, and in 1935 the army bombers had become too large to be maintained and stored at Luke Field. Construction began on a new Army airfield, Hickam Army Airfield, named after pioneer U.S. Army Air Corps pilot Lieutenant Colonel Horace Meek Hickam. From 1936 to 1940 Pan American flew its Clipper service into Ford Island, using it as a refueling stop between the United States and Asia. The Navy built a $25,000 boathouse, spent $579,565 on a new crew barracks and built a firehouse, water-supply and lighting systems. In June 1936 the Navy lengthened the island's landing field by 400 feet (120 m), to 3,000 feet (910 m). In March 1937 Amelia Earhart, on her second visit to Luke Field, crashed her Lockheed Electra on takeoff.
In 1939, after three years of construction, Hickam Field opened. The Army transferred its operations there, leaving Luke Field under Navy control. The latter was renamed Naval Air Station Ford Island, and became the headquarters of Patrol Wing 2; its former namesake was re-honored with a new base, Luke Air Force Base in Arizona. A September 8, 1939, presidential emergency proclamation spurred the rapid construction of new facilities to prepare the island for additional operations. This included additional barracks, a new assembly and repair hangar, an administration building, a dispensary, a  control tower, a laundry and a theater. At the height of World War II, over 40,000 people lived or worked on the island. 
Question: Who built a firehouse, water-supply and lighting system?
Example Output:
The Navy.
