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.

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

Passage: There were many prominent women at court during and after Wu's reign, including Shangguan Wan'er (664–710), a poet, writer, and trusted official in charge of Wu's private office. In 706 the wife of Emperor Zhongzong of Tang, Empress Wei (d. 710), persuaded her husband to staff government offices with his sister and her daughters, and in 709 requested that he grant women the right to bequeath hereditary privileges to their sons (which before was a male right only). Empress Wei eventually poisoned Zhongzong, whereupon she placed his fifteen-year-old son upon the throne in 710. Two weeks later, Li Longji (the later Emperor Xuanzong) entered the palace with a few followers and slew Empress Wei and her faction. He then installed his father Emperor Ruizong (r. 710–712) on the throne. Just as Emperor Zhongzong was dominated by Empress Wei, so too was Ruizong dominated by Princess Taiping. This was finally ended when Princess Taiping's coup failed in 712 (she later hanged herself in 713) and Emperor Ruizong abdicated to Emperor Xuanzong.
During the 44-year reign of Emperor Xuanzong, the Tang dynasty reached its height, a golden age with low economic inflation and a toned down lifestyle for the imperial court. Seen as a progressive and benevolent ruler, Xuanzong even abolished the death penalty in the year 747; all executions had to be approved beforehand by the emperor himself (these were relatively few, considering that there were only 24 executions in the year 730). Xuanzong bowed to the consensus of his ministers on policy decisions and made efforts to staff government ministries fairly with different political factions. His staunch Confucian chancellor Zhang Jiuling (673–740) worked to reduce deflation and increase the money supply by upholding the use of private coinage, while his aristocratic and technocratic successor Li Linfu (d. 753) favored government monopoly over the issuance of coinage. After 737 most of Xuanzong's confidence rested in his long-standing chancellor Li Linfu, who championed a more aggressive foreign policy employing non-Chinese generals. This policy ultimately created the conditions for a massive rebellion against Xuanzong.
What is the name of the Emperor who staunch Confucian chancellor worked to reduce deflation and increase the money supply?

Passage: From the days of 78 rpm discs, when relatively little modern music was being put on record, Walton was favoured by the record companies. In 1929 the small, new Decca company recorded eleven movements from Façade, with the composer conducting a chamber ensemble, with the speakers Edith Sitwell and Walton's friend and colleague Constant Lambert.       In the 1930s, Walton also had two of his major orchestral works on disc, both on Decca, the First Symphony recorded by Harty and the London Symphony Orchestra, and the Viola Concerto with Frederick Riddle and the LSO conducted by the composer. In the 1940s Walton moved from Decca to its older, larger rival, EMI. The EMI producer Walter Legge arranged a series of recordings of Walton's major works and many minor ones over the next twenty years; a rival composer expressed the view that if Walton had an attack of flatulence (he used an earthier expression), Walter Legge would record it.Walton himself, although a reluctant conductor, conducted many of the EMI recordings, and some for other labels. He made studio recordings of the First Symphony, the Viola Concerto, the Violin Concerto, the Sinfonia Concertante, the Façade Suites, the Partita, Belshazzar's Feast, and suites from his film scores for Shakespeare plays and The First of the Few. Some live performances conducted by Walton were recorded and have been released on compact disc, including the Cello Concerto and the Coronation Te Deum.Almost all Walton's works have been recorded for commercial release. EMI published a "Walton Edition" of his major works on CD in the 1990s, and the recording of the Chandos Records "Walton Edition" of his works was completed in 2010. His best-known works have been recorded by performers from many countries. Among the frequently recorded are Belshazzar's Feast, the Viola and Violin Concertos and the First Symphony, which has had more than twenty recordings since Harty's 1936 set.
What is the name of the person conducting a chamber ensemble, with the speaker Edith Sitwell?
