Input: Consider Input: Question: Who was older the year Dane appeared on Jackie Gleason's show, Otis Spann or Willie Dixon? Passage:By 1959, Louis Armstrong had asked Time magazine readers: "Did you get that chick? She's a gasser!" and invited her to appear with him on national television. She appeared with Armstrong on the Timex All-Star Jazz Show hosted by Jackie Gleason on January 7, 1959. She toured the East Coast with Jack Teagarden, appeared in Chicago with Art Hodes, Roosevelt Sykes, Little Brother Montgomery, Memphis Slim, Otis Spann, Willie Dixon and others, played New York with Wilbur De Paris and his band, and appeared on The Tonight Show Starring Johnny Carson as a solo guest artist. Other national TV work included The Steve Allen Show, Bobby Troup's Stars of Jazz, and Alfred Hitchcock Presents. In 1961, the singer opened her own club, Sugar Hill: Home of the Blues, on San Francisco's Broadway in the North Beach district, with the idea of creating a venue for the blues in a tourist district where a wider audience could hear it. There Dane performed regularly with her two most constant musical companions: Kenny "Good News" Whitson on piano and cornet and Wellman Braud, former Ellington bassist.

Input: Consider Input: Question: How many weeks did the single that peaked at number nine spend on the charts? Passage:"Go Girl" was the first single released from the album. It was originally the lead single from the album, but the single achieved minimum success and was later deemed a promo single. However, the single managed to reach the top of the charts in Japan. The album's official lead single, "Never Ever", which features Young Jeezy, was released in the United States in January 2009 and reached a peak of number nine on the U.S. Hot R&B/Hip-Hop Songs. The second single, "Love Sex Magic", featuring Justin Timberlake, became a worldwide hit, peaking within the top ten in twenty countries including the U.S., where it peaked at number ten on the Billboard Hot 100. It went on to be certified platinum in Australia and received a gold accreditation in New Zealand. It received a nomination for "Best Pop Collaboration with Vocals" at the 52nd Annual Grammy Awards and also for Best Choreography in a Video at the 2009 MTV Video Music Awards. "Like A Surgeon" was the fourth single from the album. The song received no promotion and no single cover nor music video was released. However, the song did manage to peak at number fifty-nine on the Hot R&B/Hip-Hop Songs chart from airplay alone. "Work", the final single, achieved moderate success in international markets.

Input: Consider Input: Question: Who designed the American automobile that was developed in 1908? Passage:With the development of the Ford Model T in 1908, automobiles became affordable for the average American citizen. But few paved roads or highways existed, as long-distance overland travel was done by railroad and local transportation was horse-drawn. In the early 1910s, the National Park Service conceived of building a paved highway between Yellowstone National Park and Glacier National Park as a means of encouraging tourism in both parks. It helped establish "citizens associations" in both parks to lobby for state and federal funds for road construction. At first, the lack of a national transportation policy hindered these efforts. Later, World War I diverted funds and material to war use. In 1919, however, the first Geysers-to-Glaciers Highway opened. This two-lane highway followed what is now US 89 W from the Yellowstone border to Livingston, and then followed U.S. Route 191/Interstate 90 west through Bozeman to Three Forks. It then went north along what is now U.S. Route 287/Interstate 15 until it reached Exit 228, at which point it continued to follow the old Mullan Road route along U.S. Route 287 and Montana Highway 200 to Great Falls. From Great Falls, it continued north on what is now Interstate 15 to Shelby, then went west along current U.S. Route 2 from Shelby to Cut Bank. At that point, it went north along the Glacier National Park border, following current MT 213 from Cut Bank to the Canada–U.S. border. In 1920, a shorter eastern route known as the Yellowstone-Glacier Beeline Highway opened. The "Y-G Beeline" continued to follow U.S. Route 89 from Livington, until it reached Great Falls. It rejoined the Geysers-to-Glaciers Highway thereafter.
