Passage: Nine Inch Nails, an industrial rock band fronted by Trent Reznor, has toured all over the world since its creation in 1988. While Reznorthe only official member until adding Atticus Ross in 2016controls 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?
Trent Reznor.

Passage: Donald's Dilemma starts with Daisy narrating her problem to an unseen psychologist through flashback scenes. Her problem started on a spring day when she was out on a date with Donald and a flower pot fell on his head. He regained consciousness soon enough but with some marked differences. His singing voice was improved to the degree in which it sounds identical to Frank Sinatra. However, Donald had no memory of who Daisy was. He became a well-known crooner and his rendition of "When You Wish Upon a Star" from Pinocchio (which had been released seven years earlier) became a hit, which gave him a large number of fans. Daisy's loss resulted in a number of psychological symptoms - she suffered from anorexia, insomnia and self-described insanity. An often censored scene features her losing her will to live and pointing a gun at her head, while in front of a table of other different suicidal methods, including a noose, a grenade, a bomb, a knife, and poison. She decided that she would see Donald once again, at any cost, but failed to do so. That's when she decided to go to the psychologist - and the flashback meets the actual time of the cartoon.
At the end of the cartoon, the psychologist determines that Donald would regain his memory of Daisy if another flower pot (with the same flower from the first pot, which Daisy kept as the only thing she had to remember Donald) would fall on his head. But he warns that his improved voice may be lost along with his singing career. He offers Daisy a dilemma. Either the world has its singer but Daisy loses him or Daisy regains Donald but the world loses him. Posed with the question "her or the world", Daisy answers with a resounding and possessive scream - "Me! Me! Me! MEEE!!". Soon, Donald returns to his old self and forgets about his singing career and Daisy regains her lover.
Question: Whose singing voice improved after being hit on the head with a flower pot?
Donald.

Passage: The commission for the brand new house of Knightshayes Court was obtained from Sir John Heathcoat-Amory in 1867 and the foundation stone was laid in 1869. By 1874, the building was still incomplete, owing to ongoing difficulties with Heathcoat-Amory, who objected to many of Burges's designs on the grounds of cost and of style. Although work had begun on the interior, the turbulent relationship between architect and client led to Burges's sacking in 1874 and his replacement by John Dibblee Crace. Nevertheless, Knightshayes Court remains the only example of a medium-sized Burges country house, built in a standard Victorian arrangement. Early French Gothic in style, it follows a standard neo-Tudor plan of a large central block with projecting gables. The tower Burges planned was never built.
The interior was to have been a riot of Burgesian excess but not a single room was completed to Burges's designs. Of the few interior features that were fully executed, much was altered or diluted by Heathcoat-Amory and his successors. However some of the interiors, such as the library, vaulted hall and the arched red drawing room, remain or have been re-instated.Since the house passed to the National Trust in 1972, major works of restoration and re-creation have been undertaken and a number of pieces of Burges furniture, mostly not original to the house, are displayed. These include a bookcase from Buckingham Street and a chimney piece from the Hall at Worcester College, Oxford, where, in the 1960s, some decorative works by Burges were removed, although his redecoration of the college Chapel remains. The aim is, as far as possible, to reinstate the work of Burges and Crace.
Question: Where did the National Trust get a bookcase for the house they took ownership of in 1972?
Buckingham Street.
