input question: Given the following context: Bellette and Haefliger returned to Australia just before the outbreak of World War II. Shortly after her arrival, Bellette held an exhibition at Sydney's Macquarie Galleries. The couple became influential members of the Sydney Art Group, a network of "fashionable" moderns whose membership included William Dobell and Russell Drysdale. Bellette painted and held regular shows "a solo show every second year and a group show every year at the Macquarie Galleries". Her husband served as art critic for The Sydney Morning Herald for a decade and a half.In 1942, Bellette won the Sir John Sulman Prize with For Whom the Bell Tolls. She won it again in 1944 with her painting Iphigenia in Tauris, inspired by Euripides' play. The composition is set in a dry, open landscape, with several riders on horses whose appearance suggests "the Australian present, rather than Greek antiquity". The judge awarding the prize actually preferred another of her entries, Electra, depicting the sister of Iphigenia also prominent in Greek tragedy but it failed to meet the size requirements. Both Iphigenia in Tauris and Electra were among the many works created by Bellette in the 1940s that were inspired by the tragedies of Euripides, Sophocles and Homer. Her choice of subject matter and approach placed her at odds with mainstream modernism, while she seemed to shun explicit links between the classical and the Australian. Bellette reasoned that she preferred to choose her palette and the spatial arrangements of her compositions to evoke a place's atmosphere. Critics identified the influence of European modernists Aristide Maillol and Giorgio de Chirico, as well as Italian Quattrocento painters Masaccio and Piero della Francesca, about some of whom Bellette wrote articles in the journal Art in Australia.The most distinctive feature of the artist's work was this choice of classical subjects. In 1946, Bellette's paintings were hung in at least four separate exhibitions. Reviewers commented on her synthesis of "the impulsiveness of romanticism... answer the following question: Whose "romantically classical" approach was commented on by reviewers????
output answer: Bellette

Given the following context: During the 1950s, Szigeti began to develop arthritis in his hands and his playing deteriorated. Despite his weakened technical mastery, his intellect and musical expression were still strong, and he continued to draw large audiences to his concerts. In Naples, Italy, in November 1956, just after the Soviets crushed the Hungarian uprising, as soon as he walked onto the stage the audience burst into wild applause and shouts of Viva l'Ungheria! (Italian for "Long live Hungary!"), delaying the concert for nearly fifteen minutes.In 1960 Szigeti officially retired from performing, and returned to Switzerland with his wife. There he devoted himself primarily to teaching, although he still traveled regularly to judge international violin competitions. Top-class students from all over Europe and the United States came to study under him. One of these students was Arnold Steinhardt, who spent the summer of 1962 with Szigeti. He came to the conclusion that "Joseph Szigeti was a template for the musician I would like to become: inquisitive, innovative, sensitive, feeling, informed".Toward the end of his life, Szigeti suffered from frail health. He was put on strict diets and had several stays in hospital, but his friends asserted that this did nothing to dampen his characteristic cheerfulness. He died in Lucerne, Switzerland on February 19, 1973, at the age of 80. The New York Times ran a front-page obituary that ended with this 1966 quote from violinist Yehudi Menuhin: We must be humbly grateful that the breed of cultured and chivalrous violin virtuosos, aristocrats as human beings and as musicians, has survived into our hostile age in the person of Joseph Szigeti. answer the following question: What is the last name of the person who had weakened technical mastery?
----
Answer: Szigeti

Problem: Given the question: Given the following context: Although the Silk Road from China to Europe and the Western World was initially formulated during the reign of Emperor Wu (14187 BC) during the Han, it was reopened by the Tang in 639 when Hou Junji (d. 643) conquered the West, and remained open for almost four decades. It was closed after the Tibetans captured it in 678, but in 699, during Empress Wu's period, the Silk Road reopened when the Tang reconquered the Four Garrisons of Anxi originally installed in 640, once again connecting China directly to the West for land-based trade. The Tang captured the vital route through the Gilgit Valley from Tibet in 722, lost it to the Tibetans in 737, and regained it under the command of the Goguryeo-Korean General Gao Xianzhi. When the An Lushan Rebellion ended in 763, the Tang Empire had once again lost control over its western lands, as the Tibetan Empire largely cut off China's direct access to the Silk Road. An internal rebellion in 848 ousted the Tibetan rulers, and Tang China regained its northwestern prefectures from Tibet in 851. These lands contained crucial grazing areas and pastures for raising horses that the Tang dynasty desperately needed.Despite the many expatriate European travelers coming into China to live and trade, many travelers, mainly religious monks and missionaries, recorded the strict border laws that the Chinese enforced. As the monk Xuanzang and many other monk travelers attested to, there were many Chinese government checkpoints along the Silk Road that examined travel permits into the Tang Empire. Furthermore, banditry was a problem along the checkpoints and oasis towns, as Xuanzang also recorded that his group of travelers were assaulted by bandits on multiple occasions. The Silk Road also affected Tang dynasty art. Horses became a significant symbol of prosperity and power as well as an instrument of military and diplomatic policy. Horses were also revered as a relative of the dragon. answer the following question: What did China regain control of under the command of the Goguryeo-Korean General Gao Xianzhi?

The answer is:
the vital route through the Gilgit Valley
