In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

[Q]: Passage: The Tang dynasty was largely a period of progress and stability in the first half of the dynasty's rule, until the devastating An Lushan Rebellion (755-763) and the decline of central authority in the later half of the dynasty. Like the previous Sui dynasty, the Tang dynasty maintained a civil-service system by recruiting scholar-officials through standardized examinations and recommendations to office.  The rise of regional military governors known as jiedushi during the 9th century undermined this civil order.  Chinese culture flourished and further matured during the Tang era; it is traditionally considered the greatest age for Chinese poetry.  Two of China's most famous poets, Li Bai and Du Fu, belonged to this age, as did many famous painters such as Han Gan, Zhang Xuan, and Zhou Fang.  Scholars of this period compiled a rich variety of historical literature, as well as encyclopedias and geographical works. The adoption of the title Tängri Qaghan by the Tang Emperor Taizong in addition to his title as emperor was eastern Asia's first "simultaneous kingship".Many notable innovations occurred under the Tang, including the development of woodblock printing.  Buddhism became a major influence in Chinese culture, with native Chinese sects gaining prominence.  However, in the 840s the Emperor Wuzong of Tang enacted policies to persecute Buddhism, which subsequently declined in influence. Although the dynasty and central government had gone into decline by the 9th century, art and culture continued to flourish. The weakened central government largely withdrew from managing the economy, but the country's mercantile affairs stayed intact and commercial trade continued to thrive regardless. However, agrarian rebellions in the latter half of the 9th century resulted in damaging atrocities such as the Guangzhou massacre of 878–879. 
Question: Under what dynasty were the jiedushi created?
[A]: Tang dynasty.


[Q]: Passage: The bulk of the larger states, and some groups of small states, were integrated through a different, four-step process. The first step in this process was to convince groups of large states to combine to form a "princely union" through the execution by their rulers of Covenants of Merger. Under the Covenants of Merger, all rulers lost their ruling powers, save one who became the Rajpramukh of the new union. The other rulers were associated with two bodies—the council of rulers, whose members were the rulers of salute states, and a presidium, one or more of whose members were elected by the rulers of non-salute states, with the rest elected by the council. The Rajpramukh and his deputy Uprajpramukh were chosen by the council from among the members of the presidium. The Covenants made provision for the creation of a constituent assembly for the new union which would be charged with framing its constitution. In return for agreeing to the extinction of their states as discrete entities, the rulers were given a privy purse and guarantees similar to those provided under the Merger Agreements.Through this process, Patel obtained the unification of 222 states in the Kathiawar peninsula of his native Gujarat into the princely union of Saurashtra in January 1948, with six more states joining the union the following year. Madhya Bharat emerged on 28 May 1948 from a union of Gwalior, Indore and eighteen smaller states. In Punjab, the Patiala and East Punjab States Union was formed on 15 July 1948 from Patiala, Kapurthala, Jind, Nabha, Faridkot, Malerkotla, Nalargarh, and Kalsia. The United State of Rajasthan was formed as the result of a series of mergers, the last of which was completed on 15 May 1949. Travancore and Cochin were merged in the middle of 1949 to form the princely union of Travancore-Cochin. The only princely states which signed neither Covenants of Merger nor Merger Agreements were Kashmir, Mysore and Hyderabad. 
Question: What was the name of the union that was formed between Gwalior, Indore and eighteen smaller states?
[A]: Madhya Bharat.


[Q]: Passage: Despite a political climate that was unfavorable to modern art (often denounced as "formalist" by the communist authorities), post-war Polish composers enjoyed an unprecedented degree of compositional freedom following the establishment of the Warsaw Autumn festival in 1956. Górecki had won recognition among avant-garde composers for the experimental, dissonant and serialist works of his early career; he became visible on the international scene through such modernist works as Scontri, which was a success at the 1960 Warsaw Autumn, and his First Symphony, which was awarded a prize at the 1961 Paris Youth Bienniale. Throughout the 1960s, he continued to form acquaintanceships with other experimental and serialist composers such as Pierre Boulez and Karlheinz Stockhausen.
During the 1970s, Górecki began to distance himself from the serialism and extreme dissonance of his earlier work, and his Third Symphony, like the preceding choral pieces Euntes ibant et flebant (Op. 32, 1972) and Amen (Op. 35, 1975), starkly rejects such techniques. The lack of harmonic variation in Górecki's Third Symphony, and its reliance on repetition, marked a stage in Górecki's progression towards the harmonic minimalism and the simplified textures of his more recent work. Because of the religious nature of many of his works during this period, critics and musicologists often align him with other modernist composers who began to explore radically simplified musical textures, tonality, and melody, and who also infused many of their works with religious significance. Like-minded composers, such as Arvo Pärt and John Tavener, are frequently grouped with Górecki under the term "holy minimalism," although none of the composers classified as such has admitted to common influences. 
Question: What is the last name of the person who continued to form acquaintanceships with other experimental and serialist composers?
[A]:
Górecki.
