[Q]: Question: How long is the river that's located in western Sweetwater County? Passage:It rises in western Wyoming, in northern Sublette County, on the western side of the Continental Divide in the Bridger–Teton National Forest in the Wind River Range. It flows south through Sublette County and western Wyoming in an area known as the Upper Green River Valley, then southwest and is joined by the Big Sandy River in western Sweetwater County. At the town of La Barge, it flows into Fontenelle Reservoir, formed by Fontenelle Dam. Below there, it flows through open sage covered rolling prairie where it is crossed by the Oregon, California and Mormon emigration trails and then further south until it flows past the town of Green River and into the Flaming Gorge Reservoir in Southwestern Wyoming, formed by the Flaming Gorge Dam in northeastern Utah. Prior to the creation of the reservoir, the Blacks Fork joined the Green River south of Green River, today the mouth of Blacks Fork is submerged by the reservoir.

[Q]: Question: When did the Tokyo Kaisei school change it's name? Passage:The Japanese exhibition at the fair was the product of years of preparation. The empire had received its invitation in 1871, close on the heels of the Meiji Restoration, and a government bureau was established to produce an appropriate response. Shigenobu Okuma, Tsunetami Sano, and its other officials were keen to use the event to raise the international standing of Japanese manufactures and boost exports. 24 engineers were also sent with its delegation to study cutting-edge Western engineering at the fair for use in Japanese industry. Art and cultural relics at the exhibit were verified by the Jinshin Survey, a months-long inspection tour of various imperial, noble, and temple holdings around the country. The most important products of each province were listed and two specimens of each were collected, one for display in Vienna and the other for preservation and display within Japan. Large-scale preparatory exhibitions with this second set of objects were conducted within Japan at the Tokyo Kaisei School (today the University of Tokyo) in 1871 and at the capital's Confucian Temple in 1872; they eventually formed the core collection of the institution that became the Tokyo National Museum.

[Q]: Question: What is the setting of the opera in which Sheridan appeared in July of 1919? Passage:Sheridan had her early vocal training while at school at the Dominican Convent in Eccles Street, Dublin, with additional lessons from Vincent O'Brien. In 1908, she won a gold medal at the Feis Ceoil. From 1909 to 1911 she studied at the Royal Academy of Music in London, during which time she was introduced to the Italian inventor Guglielmo Marconi, who was instrumental in arranging further studies for her in opera in Rome. With Marconi's help she auditioned in 1916 for Alfredo Martino, a prominent singing teacher attached to the Teatro Costanzi, and she made her début there in January 1918 in Puccini's La Bohème. In July 1919 she appeared at the Royal Opera House (Covent Garden) in the title role in Iris by Pietro Mascagni. Sheridan returned to Italy, where her career continued to grow, with performances at the Teatro Dal Verme in Milan and at the Teatro San Carlo in Naples, primarily in Puccini roles. In 1922 she first sang at La Scala, Milan, in La Wally by Catalani under the direction of Toscanini. For the next few years she would sing at La Scala with great success. Perhaps her greatest role was Madama Butterfly, which she sang extensively in Italy and at Covent Garden. When she played the part of Madama Butterfly, Puccini was said to be spellbound.
