instruction:
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.
question:
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 19491950. 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 Rosandic 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.
answer:
What is the full name of the man who's project has increased the plants at Sissinghurst from 400 to 530?

question:
Passage: In writing Young Modern, Johns tried to make the music sound very simple, despite a complex musical structure. The lyrics were written after the music was created, sometimes as late as the day of recording. As Johns dreads writing lyrics, he suggested that the band could produce an instrumental album at some stage in the future. Johns is the band's primary songwriter, and notes that while Joannou and Gillies do not have significant influence on what he writes, they are key to the band's overall sound. For that album, Hamilton co-wrote four songs with Johns including the APRA Award-winning "Straight Lines". Joannou believed that Young Modern was simpler than Diorama but "still as complex underneath with simple pop song elements". He said that much of the band's success resulted from trying to push themselves harder in recording and writing. Self-producing has allowed the band to do so without the pressures of a record label.Gillies notes that Silverchair will often "run the risk of losing fans" with their work, and this was evident in the changes in musical direction in Diorama and Young Modern. However, he described this as a good thing, describing the fact "that we haven't been pigeonholed, and people really don't know what to expect" as one of the attractive elements of the band. Despite the ups and downs of success at a young age, Gillies says the band "appreciate what we've achieved and what we've got" in their careers. The band have received six APRA Awards with Johns winning three songwriting awards at the 2008 ceremony.
answer:
What is the name of the band John's suggested could produce an instrumental album at some stage in the future?

question:
Passage: Danny Kaye plays a double role as a pair of estranged "super-identical (monozygotic) twins", with very similar looks, but very different personalities. Buster Dingle, who goes by the stage name "Buzzy Bellew", is a loud and goofy performer at a classy nightclub (the Pelican Club), while Edwin Dingle is a studious, quiet bookworm writing a history book. The two brothers have not seen each other for years.
Buster becomes the witness to a murder committed by mob boss "Ten Grand" Jackson, and is promptly murdered himself. He comes back as a ghost, calling on his long-lost brother for help to bring the killer to justice. As a result, the shy Edwin must take his brother's place until after his testimony is given.
In the meantime, he has to dodge Jackson's hitmen and fill in for Buster at the nightclub. To help him out, Busterwho cannot be seen or heard by anyone but Edwinpossesses him, with outrageously goofy results.
A famous scene features Edwin, possessed by Buzzy, performing at the Club. Under Buzzy's influence, Edwin pretends to be a famous Russian singer with an allergy to flowers. A vase of flowers is nonetheless placed on a table near him, and his song, "Otchi Chornya", is frequently interrupted by his loud and goofy-sounding sneezes.
The story is further humorously complicated by the love interests of the brothers; whilst the murdered Buster was engaged to entertainer Midge Mallon, Edwin is admired by librarian Ellen Shanley.
In the end, Ellen marries Edwin, whilst Midge consoles herself (apparently without regret) by marrying the owner of the club where Buster was appearing.
answer:
What is the full name of the person that the ghost calls on for help bringing the mob boss to justrice?
