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: Did the war that Hurst served in last longer than 2 years? Passage:Aurthur Frederick Hertz was born in Bradford to Fanny Mary and William Martin Hertz, a merchant of German Jewish descent. Hertz changed the spelling of his surname to Hurst in 1916. He attended Bradford Grammar School and Manchester Grammar School before graduating from Magdalene College, Oxford in 1904. He joined the staff of Guy's Hospital in 1906 and ran his own private practice before serving in World War I as a consulting physician stationed in Salonika. From 1916 to 1918, Hurst led the neurology department at Netley Hospital. Seale-Hayne College was repurposed as a military hospital that same year. Hurst moved there to help with treatment of shell shock, working at Netley until 1919. After the war, Hurst relocated his private practice to Windsor and retired in 1939. Upon his retirement, Hurst became a consulting physician and served on Guy's Hospital board of governors. Hurst was knighted in 1937 six years after his older brother Gerald Berkeley Hurst. He died in Birmingham in 1944, aged 65.

Question: Do more people live in the town where Thomas was raised than the one where he was born?

He played junior hockey for the Toronto Marlboros of the OHL (he was the last original Toronto Marlboro to make it to the Maple Leafs of the NHL). Prior to playing in the NHL, Thomas won the Dudley "Red" Garrett Memorial Award in 1985 as the top rookie in the American Hockey League, while playing for the St. Catharines Saints.
