In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

[Q]: Passage: In 1990, Zappa was diagnosed with terminal prostate cancer. The disease had been developing unnoticed for ten years and was considered inoperable. After the diagnosis, Zappa devoted most of his energy to modern orchestral and Synclavier works. Shortly before his death in 1993 he completed Civilization Phaze III, a major Synclavier work which he had begun in the 1980s.In 1991, Zappa was chosen to be one of four featured composers at the Frankfurt Festival in 1992 (the others were John Cage, Karlheinz Stockhausen, and Alexander Knaifel). Zappa was approached by the German chamber ensemble Ensemble Modern which was interested in playing his music for the event. Although ill, he invited them to Los Angeles for rehearsals of new compositions and new arrangements of older material. Zappa also got along with the musicians, and the concerts in Germany and Austria were set up for later in the year. Zappa also performed in 1991 in Prague, claiming that "was the first time that he had a reason to play his guitar in 3 years", and that that moment was just "the beginning of a new country", and asked the public to "try to keep your country unique, do not change it into something else".In September 1992, the concerts went ahead as scheduled but Zappa could only appear at two in Frankfurt due to illness. At the first concert, he conducted the opening "Overture", and the final "G-Spot Tornado" as well as the theatrical "Food Gathering in Post-Industrial America, 1992" and "Welcome to the United States" (the remainder of the program was conducted by the ensemble's regular conductor Peter Rundel). Zappa received a 20-minute ovation. G-Spot Tornado was performed with Canadian dancer Louise Lecavalier. It was his last professional public appearance as the cancer was spreading to such an extent that he was in too much pain to enjoy an event that he otherwise found "exhilarating". Recordings from the concerts appeared on The Yellow Shark (1993), Zappa's last release during his lifetime, and some material from studio rehearsals appeared on the posthumous Everything Is Healing Nicely (1999).
[A]: In what city was Zappa's last professional public appearance?


[Q]: Passage: In support of Nine Inch Nails' third full-length studio album, The Fragile, the live-band reformed for the Fragility tour.  The lineup remained largely the same from the Self-Destruct tour, featuring Finck, Clouser, and Lohner.  To replace long-time member Vrenna, Reznor held open auditions to find a new drummer, eventually picking then-unknown Jerome Dillon.  Dillon would remain a member of the live band until 2005.
Nine Inch Nails' record label at the time, Interscope Records, reportedly refused to fund the promotional tour following The Fragile's lukewarm sales.  Reznor instead committed himself to fund the entire tour out of his own pocket, concluding that "The reality is, I’m broke at the end of the tour," but also adding "I will never present a show that isn’t fantastic."The Fragility tour began in late 1999, running until mid-2000, and was broken into two major legs, Fragility 1.0 and Fragility 2.0 respectively.  Destinations included Europe, Japan, New Zealand, Australia, and North America.  Before the first Fragility performance date in Spain, Nine Inch Nails opened their final rehearsal in London to 100 fans. Kick-starting the tour was a performance of the title track from The Fragile at the MTV Video Music Awards.  Atari Teenage Riot opened for Nine Inch Nails during Fragility 1.0, and A Perfect Circle for Fragility 2.0.  At the time, A Perfect Circle featured Josh Freese on drums, who would later replace Dillon and play drums for Nine Inch Nails from 2005 to 2007. The tour featured increasingly large production values, including a triptych video display created by contemporary video artist Bill Viola. Rolling Stone magazine named Fragility the best tour of 2000.In 2002, the tour documentary And All That Could Have Been was released featuring a collection of performances from the Fragility 2.0 tour.  While making the DVD, Reznor commented on the tour in retrospect by saying "I thought the show was really, really good when we were doing it", but later admitted that he "can't watch [the DVD] at all. I was sick for most of that tour and I really don't think it was Nine Inch Nails at its best".
[A]: What was the name of the drummer on the Self-Destruct tour?


[Q]: Passage: Vita Sackville-West, poet, author, and gardener, was born at Knole, about 25 miles from Sissinghurst, on 9 March 1892. The great Elizabethan mansion, home of her ancestors but denied to her through agnatic primogeniture, held enormous importance for her throughout her life. Sissinghurst was a substitute for Knole, and she greatly valued its familial connections. In 1913 Sackville-West married Harold Nicolson, a diplomat at the start of his career. Their relationship was unconventional, with both pursuing multiple, mainly same-sex, affairs. After breaking with her lover Violet Trefusis in 1921, Sackville-West became increasingly withdrawn. She wrote to her mother that she would like "to live alone in a tower with her books", an ambition she achieved in the tower at Sissinghurst where only her dogs were regularly admitted.
From 1946 until a few years before her death, Sackville-West wrote a gardening column for The Observer, in which, although she never referred directly to Sissinghurst, she discussed a wide array of horticultural issues. In an article, "Some Flowers", she discussed the challenge of writing effectively about flowers: "I discovered this only when I started to do so. Before ... I found myself losing my temper with the nauseating phraseology ... and sickly vocabulary employed." In 1955, in recognition of her achievement at Sissinghurst, "bending some stubborn acres to my will", she was awarded the Royal Horticultural Society's Veitch Medal. Her biographer Victoria Glendinning considers Sissinghurst to be Sackville-West's "one magnificent act of creation".
[A]:
What is the exact name of the mansion which was the home of her ancestors?
