Question: How many years had the Astor Hotel been in business the year that Ciampa scaled the exterior of it? Passage:A bricklayer by profession, Ciampa also worked in the entertainment business throughout the late 1940s and early 1950s, starring in Larry Sunbrock's Rodeo and Thrill Circus in New York City and then traveling with the circus to various U.S. and Canadian cities. Notably, his act did not include the typical, tightly choreographed feats of circus acrobatics such as trapeze swinging or trampolining, but rather improvised climbing and leaping stunts making use of scaffolding and circus rigging. Spectators were frequently alarmed by the apparently ad libbed and obviously dangerous nature of his performances. In 1947 Ciampa was arrested for having scaled the exterior of the Astor Hotel as a publicity stunt for the Sunbrock Circus, concerning onlookers who feared that he might have been attempting suicide.

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).
