PROBLEM: 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?

SOLUTION: Tang dynasty.

PROBLEM: Passage: Wood was born in Oxford Street, London, the only child of Henry Joseph Wood and his wife Martha, née Morris. Wood senior had started in his family's pawnbroking business, but by the time of his son's birth he was trading as a jeweller, optician and engineering modeller, much sought-after for his model engines. It was a musical household: Wood senior was an amateur cellist and sang as principal tenor in the choir of St Sepulchre-without-Newgate, known as "the musicians' church".   His wife played the piano and sang songs from her native Wales. They encouraged their son's interest in music, buying him a Broadwood piano, on which his mother gave him lessons. The young Wood also learned to play the violin and viola.
Wood received little religious inspiration at St Sepulchre, but was deeply stirred by the playing of the resident organist, George Cooper, who allowed him into the organ loft and gave him his first lessons on the instrument. Cooper died when Wood was seven, and the boy took further lessons from Cooper's successor, Edwin M. Lott, for whom Wood had much less regard. At the age of ten, through the influence of one of his uncles, Wood made his first paid appearance as an organist at St Mary Aldermanbury, being paid half a crown.  In June 1883, visiting the Fisheries Exhibition at South Kensington with his father, Wood was invited to play the organ in one of the galleries, making a good enough impression to be engaged to give recitals at the exhibition building over the next three months. At this time in his life, painting was nearly as strong an interest as music, and he studied in his spare time at the Slade School of Fine Art. He remained a life-long amateur painter.After taking private lessons from the musicologist Ebenezer Prout, Wood entered the Royal Academy of Music at the age of seventeen, studying harmony and composition with Prout, organ with Charles Steggall, and piano with Walter Macfarren. It is not clear whether he was a member of Manuel Garcia's singing class, but it is certain that he became its accompanist and was greatly influenced by Garcia. Wood also accompanied the opera class, taught by Garcia's son Gustave. Wood's ambition at the time was to become a teacher of singing, and he gave singing lessons throughout his life. He attended the classes of as many singing teachers as he could, although by his own account, "I possess a terrible voice. Garcia said it would go through a brick wall. In fact, a real conductor's voice.". 
Question: What is the last name of the person whose mother gave him piano lessons?

SOLUTION: Wood.

PROBLEM: Passage: Four days after the events of the first film, former assassin John Wick retrieves his stolen 1969 Ford Mustang Mach 1 from a chop shop owned by Abram Tarasov, brother of Viggo and uncle of Iosef. John dispatches Tarasov's men in a violent rampage that heavily damages the Mustang, but spares Tarasov under the auspices of peace and returns home, cementing his weapons into the ground once again.
After car shop owner Aurelio takes John's Mustang for repairs, John is visited by Italian crime lord Santino D'Antonio. It is revealed that to complete his "impossible task"—which allowed him to retire and marry Helen—John asked Santino for help. As a form of contract, Santino swore John to a "marker", an unbreakable promise symbolized by a "blood oath" medallion. Santino presents the medallion to demand services from John, who declines, claiming that he is retired. In retaliation, Santino destroys John's home with a grenade launcher.
John travels to The Continental Hotel in New York City. Winston, the owner of the hotel, reminds John that if he rejects the marker, he will be violating one of the two unbreakable rules of the underworld: no blood on Continental grounds, and every marker must be honored. John reluctantly accepts his commitment and meets with Santino, who tasks him with assassinating his sister Gianna so he can claim her seat on the "High Table", a council of high-level crime lords. Santino sends Ares, his mute personal bodyguard, to surveil John. 
Question: What is the full name of the character who wants his sister assassinated?

SOLUTION:
Santino D'Antonio.
