PROBLEM: Passage: The river rises in northwestern Wyoming in the Absaroka Range, on the Continental Divide in southwestern Park County. The river starts where the North Fork and the South Fork of the Yellowstone River converge. The North Fork, the larger of the two forks, flows from Younts Peak. The South Fork flows from the southern slopes of Thorofare Mountain. The Yellowstone River flows northward through Yellowstone National Park, feeding and draining Yellowstone Lake, then dropping over the Upper and Lower Yellowstone Falls at the head of the Grand Canyon of the Yellowstone within the confines of the park. After passing through the Black Canyon of the Yellowstone downstream of the Grand Canyon, the river flows northward into Montana between the northern Absaroka Range and the Gallatin Range in Paradise Valley. The river emerges from the mountains near the town of Livingston, where it turns eastward and northeastward, flowing across the northern Great Plains past the city of Billings.
Link Information: Livingston is the county seat of Park County, Montana, United States. Question: In which state is the town that the Yellowstone River emerges after passing through the Gallatin Range?

SOLUTION: Answer: Montana

PROBLEM: Passage: Guyot took part to the Wars of the Third and Fourth Coalition with the Grande Armee, holding the rank of squadron commander in the Guard chasseurs-a-cheval regiment and being noted for bravery at the Austerlitz and Eylau. He fought at the minor Battle of Waren-Nossentin on 1 November 1806. A colonel in the Imperial Guard in 1807, he was created a baron of the Empire the next year and given a position in Lefebvre-Desnouettes's Guard light cavalry, commanding the Emperor's escort during the latter's brief campaign in Spain. In 1809, after the bloody battle of Aspern-Essling, Guyot was given the function of colonel commander of the Guard chasseurs-a-cheval and six weeks later he led a famous charge at the battle of Wagram. This action would bring him the rank of brigadier general. A Chamberlain of Emperor Napoleon I from March 1810, he was subsequently sent to Spain, where he won a promotion to general of division in 1811. During the Russian campaign and subsequent War of the Sixth Coalition, Guyot would serve as commander of the Guard chasseurs-a-cheval. In the 1813 campaign in Saxony, he was wounded at the battle of Lutzen and led a brilliant charge at the battle of Bautzen, before being made prisoner at the battle of Kulm, in August. Released after an exchange of prisoners, Guyot took part to the epic battle of Leipzig, before being created a count of the Empire in November of that year. The 1814 campaign in France saw general Guyot at the heart of the action, commanding cavalry at La Rothiere, Champaubert and Craonne.
