Example Input: Passage: Following a life-threatening drug addiction that developed after leaving the Chili Peppers in 1992, Frusciante completed a month of drug rehabilitation at Las Encinas in Pasadena in 1998. Shortly thereafter he was asked to rejoin the band. After several months of writing and recording, the Chili Peppers' next album, Californication was released. The album went on to sell more than 15 million copies worldwide, becoming the Chili Peppers' most successful recording to date. Frusciante's return generated much response from critics, who recognized the album as a commercial revitalization from their previous record, One Hot Minute. A two-year-long, international tour followed, which included several festival appearances, including Woodstock 1999 and Rock in Rio.
The writing and formation of By the Way began immediately following the culmination of Californication's world tour, in the spring of 2001. As with Californication, much of the creation took place in the band members' homes and other practice locations, such as a recording studio stage. Kiedis recalled of the situation: "We started finding some magic and some music and some riffs and some rhythms and some jams and some grooves, and we added to it and subtracted from it and pushed it around and put melodies to it." Frusciante and Kiedis would collaborate for days straight, discussing guitar progressions and sharing lyrics. For Kiedis, "writing By the Way...was a whole different experience from Californication. John was back to himself and brimming with confidence." Prior to recording By the Way, the Chili Peppers decided that they would again have Rick Rubin produce the album. Rubin had, in the past, granted the Chili Peppers creative freedom on their recording material; this was something they thought essential for the album to be unique, and could only occur with his return. 
Question: What was Frusciante asked to rejoin after rehab?
Example Output: the Chili Peppers.

Example Input: 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?
Example Output: Durden.

Example Input: Passage: A mysterious artist - and psychopath - named Ronnie Mason, steals a dead woman's wedding ring and money and leaves a fake suicide note. The woman's husband, Thomas Turner, when questioned by the local police, believes his dead wife might have been seeing Mason behind his back. He also believes his wife was murdered, but in the absence of other evidence, the police list it as a suicide and drop the case.
Mason leaves town, changes his name to Marsh and, using a limp he acquired jumping from the dead woman's bedroom window and a veteran's pin he steals from a fellow passenger on the L.A. bus, passes himself off as a wounded soldier and rents a room in the house of public stenographer Hilda Fenchurch and her younger sister Anne. To the consternation of professor Andrew Lang, who secretly loves Hilda, she falls for Marsh.
The scheming Marsh learns that Anne might inherit a great deal of money, so he suddenly switches his affections toward her. Hilda is jealous and suspicious. She plots to lure Marsh to a beach house and poison him. She is unable to go through with it, but when Marsh runs off, he is surprised by Thomas Turner and plunges off a steep cliff to his death. 
Question: What is the assumed last name of the person that passes for a wounded soldier?
Example Output:
Marsh.
