Q: Given the following context:  Oliver was not one to intellectualise her creativity: she preferred to talk about the process of creating her artworks rather than their meanings. Asked about how she approached her art, she stated: My work is about structure and order. It is a pursuit of a kind of logic: a formal, sculptural logic and poetic logic. It is a conceptual and physical process of building and taking away at the same time. I set out to strip the ideas and associations down to (physically and metaphorically) just the bones, exposing the life still held inside. While Oliver was reluctant to discuss meaning in her works, critics have identified recurring themes. Hannah Fink, like art critic John McDonald, noted that there is a pattern to the shapes and structures in Oliver's work. Fink described this as "a consistent vocabulary of elemental forms – the spiral, meander, loop and sphere – in a repertoire of signature archetypes". McDonald said that Nature is "omnipresent" and referred to them as organisms or their remains.Despite their organic appearance, Oliver's own view was that her work was not grounded in nature's structures.  Nevertheless, critics have identified the lifelike qualities of early pieces that resembled shells, claws or tails, or noted the apparent similarities to biological forms. McDonald commented that "For Oliver to deny nature is akin to Balthus saying there is nothing erotic about his paintings or Rothko claiming his works aren't abstract." Both major reviews of Oliver's work (Fenner's 1995 essay and Fink's 2002 journal article) draw attention to dualism and contradiction in the sculptures: Fenner describes them as "delicate and ephemeral, [yet] structurally robust and durable"; Fink sees them as "ethereal but solid, fluid yet rigid, open but closed".Oliver's sculptures are admired for their tactile nature, their aesthetics, and the technical skills demonstrated in their production. Particular works have been singled out for praise. A writer reviewing Vine in the Sydney Hilton admired how it "curls like a fairy...  answer the following question:  What is the precise name of the work that, according to Catherine Keenan, "is an engineering marvel"?
A: Vine

Question: Given the following context:  The album opens with "What You Waiting For?", an electropop, new wave, dance-rock, and funk song. Lyrically, the song discusses Stefani's fears of beginning a solo career. "Rich Girl", a collaboration with rapper Eve, is a dancehall and reggae reworking of the English duo Louchie Lou & Michie One's 1994 song "If I Was a Rich Girl", which itself interpolates the song "If I Were a Rich Man" from the 1964 musical Fiddler on the Roof. The Neptunes-produced track "Hollaback Girl" combines 1980s hip hop with dance music. It was written as a response to a derogatory comment that grunge musician Courtney Love made, referring to Stefani as a cheerleader.The fourth track "Cool" chronicles Stefani's previous relationship with Tony Kanal, featuring a new wave and synth-pop production. The song was compared to Cyndi Lauper and Madonna songs from the 1980s. "Bubble Pop Electric", the fifth track, is an electro song featuring André 3000's alias Johnny Vulture. It tells of the two having sex at a drive-in movie, and it was generally well received by critics, who drew comparisons to the 1978 film Grease and its 1982 sequel Grease 2. "Luxurious" is a 1990s-inspired R&B song that lyrically talks about the desire to be rich in love, simultaneously comparing Stefani's lover with luxuries. The seventh track, "Harajuku Girls", is a synth-pop song that was described as a tribute to Tokyo's street culture, produced by Jimmy Jam and Terry Lewis."Crash" is an electroclash song that uses automobile metaphors to describe a relationship. "The Real Thing" was described as a vintage Europop song, and features guest appearances from New Order vocalist Bernard Sumner and bassist Peter Hook. The next track, the synth-pop song "Serious", drew comparisons to Madonna's work during the early 1980s. A music video was produced for the song, but it was never officially released, although a snippet of the video surfaced on YouTube in October 2006. "Danger Zone", an electro-rock song, was widely interpreted to be about Stefani's husband Gavin Rossdale...  answer the following question:  What is the last name of the person who worked with Eve on "Rich Girl?"
Answer: Stefani

Question: Given the following context:  Lukather is the original lead guitarist for Toto, serving in that capacity for the band's entire history, as well as a lead and backing vocalist and composer. Lukather won three of his five Grammy Awards for work with Toto, twice as an artist and once as a producer. David Paich led the band's songwriting efforts during the development of 1978's Toto—he penned all but two of the album's tracks, including all four of its singles. Lukather also credits Jeff Porcaro for his leadership within the band during that period. However, Lukather's role in Toto evolved over time owing to the changing needs of the band. In August 1992, Jeff Porcaro collapsed while doing yard work at home and subsequently died of heart failure. The death profoundly affected Toto and Lukather in particular, who felt that he needed to step up and make sure the band kept going. Thus, he began taking more of a leadership role. Toto went through several lead vocalists over the years, including Bobby Kimball, Fergie Frederiksen, and Joseph Williams. After the 1990 dismissal of their fourth vocalist, Jean-Michel Byron, Toto was without a lead singer until around 1997; Lukather assumed most of the vocal duties for the band during that time. He performed lead vocals for every track on 1992's Kingdom of Desire and 1995's Tambu except for two instrumental tracks. The Tambu single "I Will Remember", co-written by Lukather and Stan Lynch, reached number 64 on UK charts. Some Tambu reviewers contrasted Lukather's vocals with those of former singers Kimball and Williams (and indeed, heavily criticized the entire album), some concert reviewers noted that he struggled vocally on certain songs, and a number of backup singers and guest vocalists accompanied the band's live shows during that period. It was not until Toto brought back Williams and Kimball to collaborate on 1998's Toto XX that Lukather returned predominantly to the role of backup vocalist.Lukather's songwriting contributions grew from a smattering of tracks on early Toto albums to co-writing...  answer the following question:  What is the name of the person David encouraged to write more songs for the band?
Answer:
Lukather
