Input: Consider Input: Question: Of the provinces populated by founders of the Qing dynasty, which one has a larger population? Passage:The Qing dynasty was founded not by Han Chinese, who form the majority of the Chinese population, but by a sedentary farming people known as the Jurchen, a Tungusic people who lived around the region now comprising the Chinese provinces of Jilin and Heilongjiang. Although the Ming dynasty held control over Manchuria since the late 1380s, Ming political existence in the region waned considerably after the death of the Yongle Emperor. What was to become the Manchu state was founded by Nurhaci, the chieftain of a minor Jurchen tribe in Jianzhou in the early 17th century. Originally a vassal of the Ming emperors, Nurhaci started to take actual control of most of Manchuria over the next several decades. In 1616, he declared himself the "Bright Khan" of the Later Jin state. Two years later he announced the "Seven Grievances" and openly renounced the sovereignty of Ming overlordship to complete the unification of those Jurchen tribes still allied with the Ming emperor. After a series of successful battles against both the Ming and various tribes in Outer Manchuria, he and his son Hong Taiji eventually controlled the whole of Manchuria. Soon after the establishment of the Qing dynasty, the territory of today's Primorsky Kray was made part of the Government-general of Jilin, and along with the lower Amur area was controlled from Ninguta (a garrison town south of today's Mudanjiang).

He then retired shortly afterwards due to brake failure. Gutiérrez finished 14th at the Chinese Grand Prix, passing Nico Hülkenberg in the closing laps. At the Russian Grand Prix, Gutiérrez made contact with Hülkenberg, forcing him to pit for a new front wing. At the Spanish Grand Prix, Gutiérrez was in 8th until he was passed by Felipe Massa, Jenson Button and Daniil Kvyat in the closing laps, dropping him to 11th. Gutiérrez finished 11th at the Monaco Grand Prix, but crossed the line 12th, after being pushed out the way by Valtteri Bottas on the final lap. Bottas was given a five-second time penalty, promoting Gutiérrez back to 11th. At the European Grand Prix, Gutiérrez made contact with Hülkenberg on the first lap, damaging his front wing.

Input: Consider Input: Question: How old was the series that Grampa and Jasper imitate? Passage:Additionally, Homer sings Billy Joel's 1983 song "Uptown Girl". After drinking the tainted juice, Grampa and Jasper sit on a bench, laughing like the title characters from the series Beavis and Butt-head, while Flanders hallucinates skeletons and dancing bears (images associated with the Grateful Dead), marching hammers (from Pink Floyd's 1982 film Pink Floyd—The Wall) and The Rolling Stones' lips and tongue logo. Mr. Burns' film is credited as "An Alan Smithee Film", a reference to the Alan Smithee pseudonym credit used by directors who wanted to be disassociated from a film on which they had lost creative control, to the detriment of the final product. When Barney drinks alcohol to prevent the bad effects from the tainted juice, a pink elephant comes to his rescue, referencing the scene in Dumbo where Dumbo and Timothy drink alcohol and see pink elephants. Seth and Munchie's dog is named Ginsberg, thought to be a reference to beat poet Allen Ginsberg. Homer putting the flowers in the policemen's rifles is a reference to the iconic October 22, 1967 Life magazine picture, "Flower Power" by Bernie Boston.
