[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 Tangri 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 878879.
Question: Under what dynasty were the jiedushi created?
[A]: Tang dynasty.

[Q]: Passage: "Halo" was composed by Ryan Tedder, lead vocalist of OneRepublic, together with Evan "Kidd" Bogart and Beyonce. In an interview for HitQuarters, Kidd narrated the events that led to writing the song. OneRepublic canceled their tour after Tedder had broken his Achilles tendon and had undergone surgery. The following day, the band sent Tedder to Los Angeles. There, he and Kidd were socializing when Tedder expressed his desire to write a song. Kidd was initially opposed to the idea because Tedder was supposed to be recuperating, but the pair went to Tedder's studio. During the writing sessions, singer Ray LaMontagne was the primary inspiration for "Halo". Kidd suggested they create a song in the style of LaMontagne's "Shelter" for Beyonce and her husband Jay-Z, and proposed the title "Halo" after hearing Tedder play "angelic" chords. They wrote the song in three hours.According to Simon Cowell, owner of the music production company Syco Entertainment, Bogart and Tedder intended "Halo" for his client, singer Leona Lewis, who could not record the song because of her tight schedule. Cowell was upset that Beyonce chose to record the song. David Balls, editor of the British media website Digital Spy, asked Tedder during an interview whether "Halo" had initially been written for Lewis. Tedder answered that he had only tentatively offered the track to Lewis, after Beyonce waited a long time before recording it. He commented:
There was this huge scandal that originally "Halo" was meant to go to Leona. That was never the case ... That song was written for Beyonce. What happened was that Beyonce waited long enough to record that song ... I thought this would be a brilliant first single for Leona, which it would have ... What I did was foolishly say to Leona's camp, "I have it on hold for another A-list artist and I'm pretty sure they'll take it, but if they don't, I just want to know if you like it enough to consider it". I sent it to them and they flipped on it. They loved it and instantly said they wanted to do it. I was like, "Wait, wait, wait, no, it's not free yet!".
Question: What is the first name of the person who broke his Achilles tendon?
[A]: Ryan.

[Q]: Passage: Tom is sleeping near the fireplace, and Jerry carefully sneaks past him. He goes up onto the dinner table and tries to reach for the food, but Tom attempts to slice him with a knife and he retreats, running up the staircase. Tom pulls the carpet off the staircase to catch Jerry, but also pulls down a large upright piano. While Jerry gets out of the piano's path, the piano crushes Tom to death. Tom's spirit ascends to the "Heavenly Express", a steam train that sends dead cats to Heaven.
Several cats are waiting to enter and the gatekeeper goes though their lives. The cats include Butch, who has lost a fight with a bulldog. Frankie, who was struck with a flat iron while singing on a backyard fence. Aloysius, who was run over and flattened by a steamroller. Even Fluff, Muff and Puff, a trio of kittens who were drowned after being thrown into a river. The gatekeeper allows them all through, as their deaths were untimely. However, he catches Tom trying to sneak past him to board the train and tells him to stand in line. The gatekeeper looks through his personal records and is disappointed by what he sees in it. Having learned that the main cause of Tom's death has been attributed to him persecuting "an innocent little mouse" all of his life and not from an accidental crushing of the piano, the gatekeeper refuses has entry to him for that action alone. He apologizes for this inconvenience, but the gatekeeper gives him a chance for a reprieve; should Tom have Jerry sign a certificate of forgiveness, he will be able to board the "Heavenly Express", which leaves in one hour. If he fails, Tom will be banished to hell where the hellhound devil awaits.
Question: Who drops the piano onto Tom?
[A]:
Tom.
