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.

Input: Consider Input: 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?

Output: Tang dynasty.


Input: Consider Input: Passage: Bartlett decided to send a team back to establish the exact location of the island that the Anderson party had approached, and to determine if Anderson had actually landed there. An injury to his knee ruled Mamen out from this mission, which was undertaken by ship's steward Ernest Chafe, with the Inuit pair, Kataktovik and Kuraluk. Chafe's group came within 2 miles (3 km) of Herald Island before being stopped by open water. A careful examination through binoculars revealed no signs of the missing party, and Chafe concluded that Anderson and company had not reached the island. Chafe and his party then returned to Shipwreck Camp.Meanwhile, on 4 February, Mackay and his group (Murray and Beuchat, joined by seaman Stanley Morris) announced they were leaving the next day, to seek land. Mackay presented Bartlett with a letter dated 1 February that began: "We, the undersigned, in consideration of the present critical situation, desire to make an attempt to reach the land." The letter requested appropriate supplies, and concluded by emphasising that the journey was on their own initiative and absolving Bartlett from all responsibilities. Bartlett allocated them a sledge, a tent, six gallons of oil, a rifle and ammunition and food for 50 days. They left on 5 February; the last sighting of them was a few days later, by Chafe and the Inuit, returning from their abortive trip to Herald Island. They found Mackay's party struggling to make headway, with some of their provisions lost and clothing and other equipment discarded to lighten their load. Beuchat in particular was in a distressed state, nearly delirious and in the throes of hypothermia. However, the party refused assistance and rejected Chafe's pleas that they return with him to Shipwreck Camp. Thereafter the only hint of their fate was a sailor's scarf belonging to Morris, later found buried in an ice floe. It was assumed that the four had either been crushed by the ice, or had fallen through it. 
Question: What were the last names of the people in Mackay's group?

Output: Murray.


Input: Consider Input: Passage: Sometime after 4 p.m. on December 6, 1989, Marc Lépine arrived at the building housing the École Polytechnique, an engineering school affiliated with the Université de Montréal, armed with a semi-automatic rifle and a hunting knife. Lépine purchased a rifle on November 21, 1989, in a Checkmate Sports store in Montreal. He had told the clerk that he was going to use it to hunt small game. Lépine had been in and around the École Polytechnique building at least seven times in the weeks leading up to December 6.
Lépine first sat in the office of the registrar on the second floor for a while. While there, he was seen rummaging through a plastic bag. He did not speak to anyone, even when a staff member asked if she could help him. Lépine left the office and was subsequently seen in other parts of the building before entering a second-floor mechanical engineering class of about sixty students at about 5:10 p.m. After approaching the student giving a presentation, he asked everyone to stop everything and ordered the women and men to opposite sides of the classroom. No one moved at first, believing it to be a joke until he fired a shot into the ceiling.Lépine then separated the nine women from the approximately fifty men and ordered the men to leave. He asked the remaining women whether they knew why they were there, and when one student replied "no," he answered: "I am fighting feminism." One of the students, Nathalie Provost, said, "Look, we are just women studying engineering, not necessarily feminists ready to march on the streets to shout we are against men, just students intent on leading a normal life." Lépine responded, "You're women, you're going to be engineers. You're all a bunch of feminists. I hate feminists." He then opened fire on the students from left to right, killing six, and wounding three others, including Provost.  Before leaving the room, he wrote the word shit twice on a student project.Lépine continued into the second-floor corridor and wounded three students before entering another room where he twice attempted to shoot a female student. When his weapon failed to fire, he entered the emergency staircase where he was seen reloading his gun. He returned to the room he had just left, but the students had locked the door; Lépine failed to unlock it with three shots fired into the door. Moving along the corridor, he shot at others, wounding one, before moving towards the financial services office where he shot and killed a woman through the window of the door she had just locked. 
Question: What is the last name of the person who was seen searching through a bag?


Output: Lépine.
