Input: Consider Input: Passage: Ali was one of several men hired by the United States Army to introduce camels as beasts of burden to transport cargo across the "Great American Desert." Eight of the men – including Ali – were of Greek origin. They arrived at the Port of Indianola in Calhoun County, Texas on the . The book Go West Greek George by Steven Dean Pastis, published in both Greek and English, specifically identifies all eight men. These pioneers were Yiorgos Caralambo (later known as Greek George), Hadji Ali (Hi Jolly, a.k.a. Philip Tedro), Mimico Teodora (Mico), Hadjiatis Yannaco (Long Tom), Anastasio Coralli (Short Tom), Michelo Georgios, Yanni Iliato, and Giorgios Costi. The Americans acquired three camels in Tunis, nine in Egypt and 21 in Smyrna: 33 in all. Ali was the lead camel driver during the US Army's experiment with the U.S. Camel Corps in using camels in the dry deserts of the Southwest. After successfully traveling round trip from Texas to California, the experiment failed, partly due to the problem that the Army's burros, horses, and mules feared the large animals, often panicking, and the tensions of the American Civil War led to Congress not approving more funds for the Corps. In 1864, the camels were finally auctioned off in Benicia, California, and Camp Verde, Texas. Ali was discharged from the Quartermaster Department of the U.S. Army at Fort McDowell in 1870.

Input: Consider Input: Passage: ABC's Wide World of Sports was unwilling to pay the price Knievel wanted for the Snake River Canyon jump, so he hired boxing promoter Bob Arum's company, Top Rank Productions, to put the event on closed-circuit television and broadcast to movie Investors in the event took a substantial loss, including promoter Don E. Branker, as well as Vince McMahon of what was then called the World Wrestling Federation. Arum partnered with Invest West Sports, Shelly Saltman's company, to secure from Invest West Sports two things: first, the necessary financing for the jump, and second, the services of Saltman, long recognized as one of America's premier public relations and promotion men, to do publicity so that Knievel could concentrate on his jumps. Knievel hired subcontractor and aeronautical engineer Doug Malewicki to build him a rocket-powered cycle to jump across the Snake River, and called it the Skycycle X-1. Malwecki's creation was powered by a steam engine built by former Aerojet engineer Robert Truax. On April 15, 1972, the X-1 was launched to test the feasibility of the launching ramp. The decision was then made to have Truax build the Skycycle X-2 and have it take off and fly more like a rocket than a motorcycle.

Output: How wide is the body of water that Evel Knievel attempted to jump across?


Input: Consider Input: Passage: When the Gilbert and Sullivan partnership collapsed after the production of The Gondoliers in 1889, their producer Richard D'Oyly Carte struggled to find successful new works to show at the Savoy Theatre. Carte produced Sullivan's grand opera, Ivanhoe at another theatre, and afterwards, he turned to Sullivan to create more comic operas for the Savoy. With Sydney Grundy, Sullivan wrote the nostalgic and sentimental Haddon Hall (1892) then, reunited with W. S. Gilbert, he produced Utopia, Limited (1893). He next returned, with his earlier collaborator F. C. Burnand, with The Chieftain (1894) and collaborated for the last time with Gilbert on The Grand Duke (1896). None of these had proved to be more than modestly successful, and Carte's other new pieces for the Savoy in the 1890s had done no better. Following the success of Sullivan's ballet Victoria and Merrie England in 1897, Carte asked Sullivan to work on another new opera for the Savoy.
