PROBLEM: Passage: Nine Inch Nails, an industrial rock band fronted by Trent Reznor, has toured all over the world since its creation in 1988. While Reznor—the only official member until adding Atticus Ross in 2016—controls its creative and musical direction in the studio, the touring band performs different arrangements of the songs. In addition to regular concerts, the band has performed in both supporting and headlining roles at festivals such as Woodstock '94, Lollapalooza 1991 and 2008, and many other one-off performances including the MTV Video Music Awards. Prior to their 2013 tour, the band had played 938 gigs.Nine Inch Nails' live performances contrast with its in-studio counterpart.
Reznor writes and performs nearly all Nine Inch Nails studio material, with occasional instrumental and vocal contributions from others artists. However, Reznor has typically assembled groups of backing musicians to interpret songs for tours and other live performances. Keyboardist Alessandro Cortini said that "if you see the show and you're used to the CDs it's pretty clear that the studio entity is different from the live entity".The only constant member of the live band is Reznor.  Live Nine Inch Nails performances are typically accompanied by lighting, stage, and video projection effects. Since 1999, the visual design components of live shows have been curated by Reznor with Rob Sheridan. Three tours have been chronicled on live albums and tour documentaries.
Critical and commercial response to Nine Inch Nails live performances has generally been positive. Critics have pointed to the concerts' aggressive on-stage dynamic and visual designs as high points. Reznor decided in 2008 to cease touring with the band after a 2009 farewell tour. The band resumed touring in 2013, with the group planning a set of concerts in the U.S. beginning September 28. 
Question: What's the full name of the man who was the only official member of Nine Inch Nails until 2016?

SOLUTION: Trent Reznor.

PROBLEM: Passage: William "Bill" Boss, a psychopathic prison warden, watches the end of The Human Centipede 2 (Full Sequence) with his accountant, Dwight Butler. Bill says that he hates the films as his feet are massaged by his secretary, Daisy. Daisy replies that she enjoyed them. In response, Bill sucks his finger and inserts it into Daisy's vagina, telling her that women should not be allowed to voice their opinions. Dwight interrupts, attempting to pitch a "brilliant idea" to fix the prison's horrible retention and violence rates, but he is interrupted by a phone call.
Bill and Dwight are then summoned to the scene of an assault within the prison. One of the officers has been stabbed by an inmate. As punishment, Bill decides to stomp on the arm of the prisoner, exposing the bone and causing immense pain. He promises to do it again when his bones are healed.
Back in the Warden's office, Bill receives a mysterious package. After Dwight asks what it contains, Bill reveals that it is a jar of specially imported, dried African clitorises which he eats "for strength." After eating a few, he receives a threatening prank phone call from one of the inmates. Bill waterboards him with three buckets of boiling water, horribly disfiguring him. The inmate tells Bill that he has lost his soul.
Governor Hughes arrives immediately afterwards, ordering Bill and Dwight to put a stop to the violence and promising that they will both be fired otherwise. In anger and retaliation, Bill orders a 'mass castration' of the inmates, and castrates one of the prisoners himself. He covers his face in the blood of the inmate and later eats the cooked testicles for lunch, calling it "Energy Food." Daisy is forced to perform fellatio on Bill while Dwight is in the room. Upon completing the act, Daisy eats one of the dried clitorises, mistaking them for candy. 
Question: What is the last name of the person who is interrupted by a phone call?

SOLUTION: Butler.

PROBLEM: Passage: Wood was born in Oxford Street, London, the only child of Henry Joseph Wood and his wife Martha, née Morris. Wood senior had started in his family's pawnbroking business, but by the time of his son's birth he was trading as a jeweller, optician and engineering modeller, much sought-after for his model engines. It was a musical household: Wood senior was an amateur cellist and sang as principal tenor in the choir of St Sepulchre-without-Newgate, known as "the musicians' church".   His wife played the piano and sang songs from her native Wales. They encouraged their son's interest in music, buying him a Broadwood piano, on which his mother gave him lessons. The young Wood also learned to play the violin and viola.
Wood received little religious inspiration at St Sepulchre, but was deeply stirred by the playing of the resident organist, George Cooper, who allowed him into the organ loft and gave him his first lessons on the instrument. Cooper died when Wood was seven, and the boy took further lessons from Cooper's successor, Edwin M. Lott, for whom Wood had much less regard. At the age of ten, through the influence of one of his uncles, Wood made his first paid appearance as an organist at St Mary Aldermanbury, being paid half a crown.  In June 1883, visiting the Fisheries Exhibition at South Kensington with his father, Wood was invited to play the organ in one of the galleries, making a good enough impression to be engaged to give recitals at the exhibition building over the next three months. At this time in his life, painting was nearly as strong an interest as music, and he studied in his spare time at the Slade School of Fine Art. He remained a life-long amateur painter.After taking private lessons from the musicologist Ebenezer Prout, Wood entered the Royal Academy of Music at the age of seventeen, studying harmony and composition with Prout, organ with Charles Steggall, and piano with Walter Macfarren. It is not clear whether he was a member of Manuel Garcia's singing class, but it is certain that he became its accompanist and was greatly influenced by Garcia. Wood also accompanied the opera class, taught by Garcia's son Gustave. Wood's ambition at the time was to become a teacher of singing, and he gave singing lessons throughout his life. He attended the classes of as many singing teachers as he could, although by his own account, "I possess a terrible voice. Garcia said it would go through a brick wall. In fact, a real conductor's voice.".
