[Q]: Passage: In the town of Red Rock, gun salesman Steve Farrell demonstrates the new Colt .45 repeating pistols to the sheriff who is impressed that the United States government just ordered two thousand of these powerful weapons for the army. The demonstration is interrupted when men arrive to transfer one of the prisoners to another jail. As he's being led away, prisoner Jason Brett grabs the pistols, shoots the sheriff, and escapes, pretending that Farrell was his partner. Convinced that Farrell was involved in the escape, the townspeople arrest the innocent gun salesman. In the coming days, Brett initiates a campaign of robberies and cold blooded murder, with regular guns being no match for his Colt .45 pistols.
Four months later, Farrell is released from jail due to a lack of evidence. The new sheriff offers him a letter clearing him of the charges if he reveals Brett's whereabouts. Reasserting his innocence, Farrell vows to go after Brett to retrieve his guns. Farrell tracks his prey into Texas and comes across a band of Indians whom Brett has killed to provide cover for a stagecoach robbery. The only survivor of the attack, Walking Bear, tells Steve about Brett's plan. As the stagecoach approaches, Steve jumps onto the stage from a rock outcropping just in time to fight off the attack by Brett's gang with his own set of Colt .45s. The only passenger on the stage, Beth Donovan, tries to prevent him from fighting off the robbers. 
Question: Who uses the gun salesman?
[A]: Jason Brett.


[Q]: Passage: Ottavio's marriage troubled Alessandro; he struggled with the burden of chastity and entertained fantasies of marrying a princess. He resented his younger brother's arrangement; during the wedding ceremony he "became more deathly pale than death itself, and, so they say, is unable to bear this thing, that he, the first-born, should see himself deprived of such splendid status and of the daughter of an Emperor." In 1546 Paul gave Pier Luigi the duchies of Parma and Piacenza as papal fiefs, a highly political move by the pope: in doing so he gave titles and wealth to Pier and appointed a lord who was subservient and owed a debt of gratitude, guaranteeing that the duchies would remain under papal control. At the same time, Ottavio was posted to the North of Italy to support Charles. By 1546 Ottavio was 22 years old, married to Margaret of Austria and an accomplished and distinguished individual. In 1547 his father was assassinated and Ottavio claimed the dukedom of Parma and Piacenza against the express wishes of both Charles, his father-in-law, and Paul. In doing so, Ottavio acted in opposition to the pope's desire to maintain the duchies as papal fiefs, and to Charles, whom he believed responsible for the plot to assassinate Pier Luigi.Titian was a personal friend of Charles; the commissioning of the portrait was most likely intended by Paul as a signal of allegiance to the emperor. Pressure from reforming monarchs in France and Spain, coupled with a general shift of influence in France's favour, ended the Farnese hold on the papacy soon after Paul's death. Ottavio excelled as a military commander and was awarded the Golden Fleece by the emperor. While the post had been given as a means to strengthen the family position, it did not come without cost. His success bred resentment amongst his family, as he began to see himself unaccountable to Rome.At the time of the portrait Paul had convinced Alessandro to retain the post, hinting that he would later succeed him as pope – an aspiration that was ultimately frustrated. As Alessandro realised the emptiness of the promise he lost confidence in both his grandfather's word and political credibility. 
Question: What was the name of Alessandro's brother?
[A]: Ottavio.


[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.
