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: New York City bouncer Frank "Tony Lip" Vallelonga is searching for new employment while the Copacabana nightclub, where he works, is closed for renovations. He is invited to an interview with Doctor Don Shirley, an eccentric African American pianist who is looking for a driver for his eight-week concert tour through the Midwest and Deep South. Don hires Tony on the strength of his references. They embark with plans to return to New York on Christmas Eve. Don's record label gives Tony a copy of the Green Book, a guide for African-American travelers to find motels, restaurants, and filling stations that would serve them.They begin the tour in the Midwest before eventually heading farther south. Tony and Don initially clash as  Don is disgusted by Tony's habits while Tony feels uncomfortable being asked to act with more refinement. As the tour progresses, Tony is impressed with Don's talent on the piano, and increasingly appalled by the discriminatory treatment that Don receives from his hosts and the general public when he is not on stage. A group of white men threatens Don's life in a bar and Tony rescues him. He instructs Don not to go out without him for the rest of the tour. 
Question: What is the last name of the person who Tony rescues?

Output: Shirley.


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: Others were less optimistic. Ramsey chose zero (a complete dud), Robert Oppenheimer chose 0.3 kilotons of TNT (1.3 TJ), Kistiakowsky 1.4 kilotons of TNT (5.9 TJ), and Bethe chose 8 kilotons of TNT (33 TJ). Rabi, the last to arrive, took 18 kilotons of TNT (75 TJ) by default, which would win him the pool. In a video interview, Bethe stated that his choice of 8 kt was exactly the value calculated by Segrè, and he was swayed by Segrè's authority over that of a more junior [but unnamed] member of Segrè's group who had calculated 20 kt. Enrico Fermi offered to take wagers among the top physicists and military present on whether the atmosphere would ignite, and if so whether it would destroy just the state, or incinerate the entire planet. This last result had been previously calculated by Bethe to be almost impossible, although for a while it had caused some of the scientists some anxiety. Bainbridge was furious with Fermi for scaring the guards who, unlike the physicists, did not have the advantage of their knowledge about the scientific possibilities. His own biggest fear was that nothing would happen, in which case he would have to head back to the tower to investigate.Julian Mack and Berlyn Brixner were responsible for photography. The photography group employed some fifty different cameras, taking motion and still photographs. Special Fastax cameras taking 10,000 frames per second would record the minute details of the explosion. Spectrograph cameras would record the wavelengths of light emitted by the explosion, and pinhole cameras would record gamma rays. A rotating drum spectrograph at the 10,000-yard (9,100 m) station would obtain the spectrum over the first hundredth of a second. Another, slow recording one would track the fireball. Cameras were placed in bunkers only 800 yards (730 m) from the tower, protected by steel and lead glass, and mounted on sleds so they could be towed out by the lead-lined tank. Some observers brought their own cameras despite the security. Segré brought in Jack Aeby's 35 mm Perfex 44. It would take the only known well-exposed color photograph of the detonation explosion. 
Question: What type of camera took the only known well-exposed color photograph of the detonation explosion?


Output: 35 mm Perfex 44.
