Passage: The unnamed Narrator is an automobile recall specialist who is unfulfilled by his job and possessions, and has developed severe insomnia. He finds catharsis by posing as a sufferer of testicular cancer and other afflictions in support groups, remedying his insomnia. His bliss is disturbed by another impostor, Marla Singer, whose presence reminds him he is attending these groups dishonestly. The two agree to split which groups they attend, but not before they exchange contact details on the premise of switching groups at short notice.
On a flight home from a business trip, the Narrator meets and interacts with soap salesman Tyler Durden. The Narrator returns home to find that his apartment has been destroyed by an explosion. Deciding against asking Marla for help, he calls Tyler, and they meet at a bar. Tyler says the Narrator is beholden to consumerism. In the parking lot, he asks the Narrator to hit him, and they begin a fistfight.
The Narrator is invited to move into Tyler's home: a large, dilapidated house in an industrial area. They have further fights outside the bar, which attract growing crowds of men. The fights move to the bar's basement where the men form Fight Club, which routinely meets for the men to fight recreationally.
Marla overdoses on pills and telephones the Narrator for help; he ignores her, but Tyler picks up the phone and goes to her apartment to save her. Tyler and Marla get sexually involved, and Tyler warns the Narrator never to talk to Marla about him. The Narrator blackmails his boss and quits his job. 
Question: What is the last name of the person who fistfights with the Narrator?

Ex Output:
Durden.

Passage: Susan Miller works as a girdle salesgirl in a big department store. She dreams of living on "the other side", among the rich. An elderly woman, calling herself Mrs. Maybelle Worthington, comes to buy some underwear. She is actually a professional swindler. Her partner Warren meets her at the department store, and reports that her "daughter" (a partner in their schemes) has run away to get married. They notice that Susan resembles the "daughter", and ask her to impersonate the missing girl at their party that evening. Susan sees an opportunity to experience life among the rich, and wear the expensive clothes she could never afford.
From that day on, Susan becomes "Linda Worthington" and accompanies "Mother Worthington" and "Uncle Warren" in their travels. They use her to attract marriageable young rich men, whom they swindle. One day in Southern California, they encounter John Wheeler, and overhear his plan to buy a yacht for $15,000. They take him for a millionaire, and use "Linda" to lure him into one of their swindles.

This time Susan/Linda falls in love with the intended victim, and it's hard for them to find their way to happiness. 
Question: What is the real first name of the person being used to attract marriageable young men?

Passage: Except for three months' formal schooling as a 12-year-old, during which he was bullied and ridiculed by his classmates, Percy was educated at home.  Rose, an autodidact with a dominating presence, supervised his music and literature studies and engaged other tutors for languages, art and drama. From his earliest lessons, Percy developed a lifelong fascination with Nordic culture; writing late in life, he said that the Icelandic Saga of Grettir the Strong was "the strongest single artistic influence on my life". As well as showing precocious musical talents, he displayed considerable early gifts as an artist, to the extent that his tutors thought his future might lie in art rather than music. At the age of 10 he began studying piano under Louis Pabst, a German immigrant then considered to be Melbourne's leading piano teacher. Grainger's first known composition, "A Birthday Gift to Mother", is dated 1893. Pabst arranged Grainger's first public concert appearances, at Melbourne's Masonic Hall in July and September 1894. The boy played works by Bach, Beethoven, Schumann and Scarlatti, and was warmly complimented in the Melbourne press.After Pabst returned to Europe in the autumn of 1894, Grainger's new piano tutor, Adelaide Burkitt, arranged for his appearances at a series of concerts in October 1894, at Melbourne's Royal Exhibition Building. The size of this enormous venue horrified the young pianist; nevertheless, his performance delighted the Melbourne critics, who dubbed him "the flaxen-haired phenomenon who plays like a master". This public acclaim helped Rose to decide that her son should continue his studies at  the Hoch Conservatory in Frankfurt, Germany, an institution recommended by William Laver, head of piano studies at Melbourne's Conservatorium of music. Financial assistance was secured through a fund-raising benefit concert in Melbourne and a final recital in Adelaide, after which mother and son left Australia for Europe on 29 May 1895. Although Grainger never returned permanently to Australia, he maintained considerable patriotic feelings for his native land, and was proud of his Australian heritage. 
Question: What is the first name of the person that displayed considerable early gifts as an artist?

Ex Output:

Percy.
