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?
Tang dynasty.

Passage: Between 9:00 pm and 10:00 pm the guards enacted a strategy whereby the police officers, backed by the bayonets of the soldiers, advanced to the crowd and arrested each a man, who was then taken into the station, disarmed, and held there. The strategy was largely successful, and by 11:00 pm the area around the station was mostly cleared, though sporadic gunfire could be heard throughout the night. Between 165 and 200 were detained in total, and the most violent of the captives were removed and taken to the police station. The news reported that four, including one police officer, were injured in the exchange, and several who resisted arrest were beaten severely.At the foundry near the Carey Street Bridge, a crowd of more than 100 gathered and threatened to set fire to the area. A contingent of the 5th under Captain Lipscomb arrived, and a volley fired over the heads of the crowd was sufficient to dissuade the crowd. An unsuccessful attempt was also made to burn a B&O transportation barge at Fell's Point. The news reported that 16 were arrested in a confrontation between citizens and the police at Lee and Eutaw, and that during the night, three separate attempts were made to set fire the 6th Regiment armory, but all were frustrated by the remaining garrison there.Just before midnight, 120–135 marines arrived at the station and reported to the governor, who ordered them to set about capturing the leaders of the mob. Governor Carroll telegraphed and advised President Hayes that order had been restored in the city.
Between 2:00 am and 3:00 am on Sunday morning, July 22, the peace was again broken and fire alarms began to ring throughout the city. To the west, at the Mount Clare Shops of the B&O, a 37-car train of coal and oil had been set on fire. Police, firefighters, and thousands of citizens flocked to the scene. A contingent of 50 marines was dispatched to the area to provide assistance. The cars which had not yet caught fire were detached from those burning, and by the time the flames were extinguished between seven and nine cars had been burned. Between $11,000 and $12,000 in damage was sustained.At 4:00 am another alarm sounded: the planing mills and lumber yard of J. Turner & Cate near the Philadelphia Wilmington & Baltimore rail depot, had been set on fire. The entire property, extending over a full city block, was destroyed. Realizing the severity of the situation, the firefighters concentrated their efforts on trying to save the surrounding structures.According to news reports, the first passenger trains left the city at 9:00 am, and continued running throughout the day. Around 10:00 am, General W. S. Hancock arrived and was followed by 360–400 federal troops from New York and Fort Monroe, who relieved those guarding Camden Station. They brought with them two 12 pounder artillery pieces. From that point on, the men of the 5th and the federal troops took turns guarding the station. 
Question: At what time was the lumber yard of J. Turner & Cate set on fire on the day where a car train of coal was set on fire?
4:00 am.

Passage: In 1917, France is embroiled in World War I. Dubois, head of the French spy bureau, offers to spare the life of a captured agent (an uncredited Mischa Auer) if he will reveal who he is protecting. Dubois suspects it is Mata Hari, a celebrated exotic dancer, but the prisoner chooses execution by firing squad.
Lieutenant Alexis Rosanoff of the Imperial Russian Air Force lands in Paris after a dangerous flight over enemy territory, bringing important dispatches from Russia. He persuades his superior, General Serge Shubin, to take him to see Mata Hari perform that night. Rosanoff is instantly smitten by her (as are most of the men of Paris). By youthful exuberance and good looks, he persuades her to spend the night with him. However, the next morning, she makes it clear to him that it was a one-time dalliance.
Carlotta secretly instructs Mata Hari to report to Andriani, their spymaster. Andriani orders her to find out from General Shubin the contents of the dispatches Rosanoff brought.
Meanwhile, when Dubois discloses his suspicions about Mata Hari to Shubin, the general laughs them off as ridiculous. However, Shubin has himself passed secret information to his lover Mata Hari, whom he is expecting for a private dinner. Rosanoff arrives unexpectedly, in case Shubin has further instructions before the pilot returns to Russia with more important dispatches. Upon learning of Rosanoff's mission, Mata Hari arranges for a confederate to steal the dispatches, photograph them and then return them undetected, while she keeps a puzzled, but delighted Rosanoff occupied. 
Question: Who warns the general about the exotic dancer?

Dubois.
