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: "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.

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

Q: Passage: In 1924, Monteux began a ten-year association with the Concertgebouw Orchestra of Amsterdam, serving as "first conductor" ("eerste dirigent") alongside Willem Mengelberg, its long-serving chief conductor. The two musicians liked and respected one another, despite the difference in their approach to music-making: Monteux was scrupulous in his adherence to a composer's score and straightforward in his performances, while Mengelberg was well known for his virtuoso, sometimes wilful, interpretations and his cavalier attitude to the score ("Ve vill make some changements", as an English player quoted him). Their preferred repertoire overlapped in some of the classics, but Mengelberg had his own favourites from Bach's St. Matthew Passion to Mahler symphonies, and was happy to leave Debussy and Stravinsky to Monteux. Where their choices coincided, as in Beethoven, Brahms and Richard Strauss, Mengelberg was generous in giving Monteux at least his fair share of them.While in Amsterdam Monteux conducted a number of operas, including Pelléas et Mélisande (its Dutch premiere), Carmen, Les Contes d'Hoffmann, a Lully and Ravel double bill of Acis et Galatée and L'Heure espagnole, Gluck's Iphigénie en Tauride (also brought to the Paris Opéra) and Verdi's Falstaff. Toscanini had been invited to conduct the last of these, but he told the promoters that Monteux was his dearest colleague and the best conductor for Falstaff.During the first eight years of his association with the Concertgebouw, Monteux conducted between fifty and sixty concerts each season. In his final two years with the orchestra other conductors, notably the rising young Dutchman Eduard van Beinum, were allocated concerts that would previously have been given to Monteux, who amicably withdrew from his position in Amsterdam in 1934. He returned many times as a guest conductor.

A: What is the full name of the rising conductor that was given concerts usually given to the man who conducted between fifty and sixty concerts each season?

Q: Passage: The bottom section of Tilden's "promontory" extension, the dining room contains the original suite of table and dining chairs designed by Heal's to Churchill's exacting requirements – (see box). An early study for a planned picture by William Nicholson entitled Breakfast at Chartwell hangs in the room. Nicholson, a frequent visitor to Chartwell who gave Churchill painting lessons, drew the  study for a finished picture which was intended as a present for the Churchills' Silver Wedding anniversary in 1933 but, disliking the final version, Nicholson destroyed it. The picture depicts the Churchills breakfasting together, which in fact they rarely did, and Churchill's marmalade cat, Tango. The tradition of keeping a marmalade cat at Chartwell, which Churchill began and followed throughout his ownership, is maintained by the National Trust in accordance with Churchill's wishes. In a letter to Randolph written in May 1942, Churchill wrote of a brief visit to Chartwell the previous week, "the goose and the black swan have both fallen victim to the fox. The Yellow Cat however made me sensible of his continuing friendship, although I had not been there for eight months".Above the dining room is the drawing room and, above that, Lady Churchill's bedroom, described by Churchill as "a magnificent aerial bower".

A:
What is the first name of the person who is a frequent visitor to Chartwell?
