Example Input: Question: At what age did Huizong's surviving son declare himself as the dynasty's tenth emperor? Passage:Emperor Huizong of Song (7 June 1082 – 4 June 1135), personal name Zhao Ji, was the eighth emperor of the Song dynasty in China. He was also a very well-known calligrapher. Born as the 11th son of Emperor Shenzong, he ascended the throne in 1100 upon the death of his elder brother and predecessor, Emperor Zhezong, because Emperor Zhezong's only son died prematurely. He lived in luxury, sophistication and art in the first half of his life. In 1126, when the Jurchen-led Jin dynasty invaded the Song dynasty during the Jin–Song Wars, Emperor Huizong abdicated and passed on his throne to his eldest son, Zhao Huan who assumed the title Emperor Qinzong while Huizong assumed the honorary title of Taishang Huang (or "Retired Emperor"). The following year, the Song capital, Bianjing, was conquered by Jin forces in an event historically known as the Jingkang Incident. Emperor Huizong, along with Emperor Qinzong and the rest of their family, were taken captive by the Jurchens and brought back to the Jin capital, Huining Prefecture in 1128. The Jurchen ruler, Emperor Taizong of Jin, gave the former Emperor Huizong a title, Duke Hunde (literally "Besotted Duke"), to humiliate him. After his surviving son, Zhao Gou, declared himself as the dynasty's tenth emperor as Emperor Gaozong, the Jurchens used him, Qinzong, and other imperial family members to put pressure on Gaozong and his court to surrender. Emperor Huizong died in Wuguo after spending about nine years in captivity.

Example Output: After his surviving son, Zhao Gou, declared himself as the dynasty's tenth emperor as Emperor Gaozong, the Jurchens used him, Qinzong, and other imperial family members to put pressure on Gaozong and his court to surrender

Example Input: Question: Which US Air Force plane that was shot down in Yugoslavia is the fastest? Passage:An important portion of the 1999 war between Yugoslavia and the NATO coalition involved combat between the Yugoslav Air Force, which was the predecessor of today's Serbian Air Force, and the opposing air forces of NATO. United States Air Force F-15s and F-16s flying mainly from Italian air force bases attacked the defending Yugoslav fighters—usually MiG-29s, which were in bad shape, due to lack of spare parts and maintenance. A total of six Yugoslav MiG-29s were shot down in 1999, of which three were shot down by USAF F-15s, one by a USAF F-16, and one by a RNAF F-16. One aircraft, according to a Serbian documentary, was hit by friendly fire from the ground. Another four were destroyed on the ground. During the course of the air war, Yugoslav anti-aircraft defenses downed a USAF F-16C and an F-117 Nighthawk, the first stealth aircraft to ever be shot down in combat.

Example Output:
