TASK DEFINITION: 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.
PROBLEM: Passage: "A symphony in subtle shades of white and green", the White Garden is considered the "most renowned" and most influential of all of Sissinghurst's garden rooms. Planned before the war, it was completed in the winter of 1949–1950. Using a palette of white, silver, grey, and green, it has been called "one of Vita and Harold's most beautiful and romantic visions". Sackville-West recorded her original inspiration in a letter to Nicolson dated 12 December 1939: "I have got what I hope will be a lovely scheme for it: all white flowers, with some clumps of very pale pink". The concept of single-colour gardens had enjoyed some popularity at the end of the 19th century, but few such gardens remained when Sissinghurst was designed. Influences for the White Garden include Hidcote and Phyllis Reiss's garden at Tintinhull, both of which Vita had seen. Gertrude Jekyll had discussed the concept, but argued for varying the white palette with the use of blue or yellow plants, advice followed by Reiss. But neither Hidcote nor Tintinhull equals the "full-scale symphony" of the White Garden at Sissinghurst. A more prosaic motivation for the colour scheme was to provide reflected illumination for Sackville-West and Nicolson as they made their way from their bedrooms at the South Cottage to the Priest's House for dinner.
The focal point of the garden was originally four almond trees, encased in a canopy of the white rose, Rosa mulliganii. By the 1960s, the weight of the roses had severely weakened the trees, and they were replaced with an iron arbour designed by Nigel Nicolson. Beneath the arbour is sited a Ming dynasty vase bought in Cairo. A lead statue of a Vestal Virgin, cast by Toma Rosandić from the wooden original which is in the Big Room, presides over the garden. Sackville-West intended that the statue should be enveloped by a weeping pear tree, Pyrus salicifolia 'Pendula', and the present tree was planted after her original was destroyed in the Great Storm of 1987. Lord considers the White Garden "the most ambitious and successful of its time, the most entrancing of its type".A possibly apocryphal story records a visit by the colour-loving gardener Christopher Lloyd, during which he is supposed to have scattered seeds of brightly coloured nasturtiums across the lawn. Troy Scott Smith, the current head gardener, is undertaking a major research project on the history of the White Garden with the intention of recreating the original planting scheme in its entirety. This project has seen the number of plants being propagated in the Sissinghurst nursery rise from 400 to over 530.

SOLUTION: What is the full name of the man who's project has increased the plants at Sissinghurst from 400 to 530?

PROBLEM: Passage: During late 1930 and early 1931, the plans were revised and streamlined. March 1931 saw the announcement of Plan F-18, which called for an International Music Hall (now Radio City Music Hall) and its 31-story office building annex to occupy the northernmost of the three blocks, located between 50th and 51st streets. The 66-story 831-foot (253 m) RCA Building would be located on the central block's western half, between 49th and 50th streets, and would house RCA and NBC offices as well as broadcasting studios. The oval-shaped retail complex would occupy the block's eastern half, with a rooftop garden. A RKO-operated sound theater would be located in the southernmost block between 48th and 49th streets. In the center of Radio City would be a new three-block-long private street running between Fifth and Sixth avenues, with a concave plaza at the midpoint. The complex would also include space for a future Metropolitan Opera venue on the northernmost block. An underground pedestrian shopping mall, which would be located above the underground bus terminal, was also added in this plan. The complex would include 28,000 windows and more than 125,000 short tons (112,000 long tons) of structural steel, according to the builders. It would cost $250 million.For the first time, a scale rendering of the proposed complex was presented to the public. The rendering was much criticized, with some taking issue with details or general dimensions of the as-yet-unconfirmed proposal, and others lambasting the location of the tall skyscrapers around the plaza. Daniel Okrent writes that "almost everyone" hated the updated plans. The renowned architectural scholar Lewis Mumford went into exile in upstate New York specifically because the "weakly conceived, reckless, romantic chaos" of the plans for Rockefeller Center had violated his sense of style. Mumford's commentary provoked a wave of blunt, negative criticism from private citizens; newspapers, such as the New York Herald Tribune; and architects, including both Frank Lloyd Wright and Ralph Adams Cram, whose styles were diametrically opposed to each other. The New York Times took note of the "universal condemnation" of the proposal, and after the complex's architects changed their plans in response to the criticism, the Times stated, "It is cheering to learn that the architects and builders of Radio City have been stirred by the public criticism of their plans." Despite the controversy over the complex's design, Rockefeller retained the Associated Architects for his project.

SOLUTION: What is the full name of the person whose sense of style was violated by the "weakly conceived, reckless, romantic chaos" within the plans for Rockefeller Center?

PROBLEM: Passage: Santamental, released in October 2003, is a collaborative project featuring several prominent musicians such as guitarists Eddie Van Halen, Slash, Steve Vai, and drummer Gregg Bissonette. When Lukather's record company, Bop City Records, approached him about recording a Christmas album, he responded with a quip about his suitability for the project. The company wanted him to do the record knowing he would approach the project with a unique angle and produce something different from the typical Christmas album. Lukather recruited keyboardist Jeff Babko and guitarist Larry Carlton, who Lukather had worked with previously, to help arrange the songs. The project was a challenge to Lukather, who had to be creative to turn the traditionally simple songs into something interesting for listeners without altering the fundamental structures. He said of the album, "But I never dreamt in a million years that I'd do a Christmas record."The musicians Lukather chose for Santamental, most of whom were involved in the hard-rock genre, lent a heavy feel to the album. Van Halen recorded guitar tracks for "Joy to the World" after not having been in the studio for some time but immediately made an impression on Lukather with his level of playing. Vai provided guitar work for "Carol of the Bells" along with Lukather's son Trevor, then 14 years old. Slash, who recorded his part in one take, played on the Lukather/Stan Lynch composition "Broken Heart for Christmas". Lukather spoke highly of Slash after the project, calling him the "Keith Richards of our generation". Well-known session guitarist Michael Landau played on the song "Look Out For Angels", and there is a version of "Jingle Bells" featuring a big band and sung by Sammy Davis, Jr. Santamental was recorded in six days, after which Lukather proclaimed it "his first and last Christmas album".

SOLUTION:
What is the first name of the person who recorded guitar tracks for "Joy to the World" after not having been in the studio for some time?
