Question: Of the three presumed first members, which of the small states was the smallest? Passage:An ancient Amphictyony, probably the earliest centered on the cult of Demeter at Anthele or Anthela (), which lay on the coast of Malis south of Thessaly. This was the locality of Thermopylae. Thus those living near the temple were called Amphictyones ("dwellers-round"). The immediate "dwellers-round", presumably the first members, were the small states Aeniania, Malis and Doris. Certainly Thessaly did have a share including the states of the Boeotian tribes who lived around Thessaly (perioikoi, "living around"). Boeotia and Phocis, the most remote of them may have joined during or after the "First Sacred War", which led to the defeat of the old priesthood, and to a new control of the prosperity of the oracle at Delphi. As a result of the war, the Anthelan body was known henceforth as the Delphic Amphictyony and became the official overseer and military defender of the Delphic cult. The name of Hellenes, which was originally the name of a Boeotian tribe in Thessalic Phthia, (Achaea Phthiotis) may likely be related to the members of that league and may have been broadened to refer to all Greeks when the myth of their patriarch Hellen was invented.

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.

Question: In what year was baseball first played in the stadium for which Rostenkowski secured a $150 million bond authority? Passage:In his book , author Charles Wheelan wrote "We Chicagoans can drive around the city and literally point to things that Rosty built." Although Rostenkowski never "literally" built anything with his own money or labor, he delivered federal funds for Chicago and the State of Illinois. Some of his notable projects include: securing $32 million for the Blue Line of the Chicago Transit Authority which expanded travel from the Chicago Loop to O'Hare International Airport, $450 million to repave and expand the Kennedy Expressway, $25 million to fix the dangerous S Curve on Lake Shore Drive $4 billion for the Deep Tunnel Project, which was designed to keep raw sewage from entering the Chicago River and Lake Michigan, while also protecting over half a million suburban and city home owners threatened by flooded basements. He followed that with $42.4 million for reservoirs in McCook and Thornton Townships and by O'Hare airport, $16.8 million for downtown's State Street Mall renovation, $3.5 million for the construction of the Cook County Boot Camp, a military-style alternative for first-time youthful offenders. When the Chicago White Sox baseball team was considering moving to Florida, Rostenkowski secured a $150 million bond authority for the construction of US Cellular Field. Once nearly abandoned and left in disrepair, he ensured $75 million in tax-free bonds for the remodeling of Navy Pier, which today has become Chicago's preeminent tourist attraction. To ease erosion that threatened Lake Shore Drive and several harbors and museums along the Chicago lake front, Rostenkowski secured $2.2 million for the Chicago Shoreline Protection Project, and laid the foundation for a coordinated partnership among the Army Corps of Engineers, the federal government and the City of Chicago. He also was responsible for securing funding for the upkeep of Chicago area bridges including the Chicago Skyway, the Division, Cermak, and Roosevelt street bridges.
