[Q]: 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.

[Q]: Question: What is one key difference between the Indus Valley civilization and early Vedic civilizations? Passage:The book discusses four prehistoric migrations in India. The book mentions that the Harappans were a mixture of Zagros agriculturists and First Indians, a wave of migrants who came from Africa into Arabia and then reached India around 65,000 years ago. Citing recent DNA evidence, the book traces the subsequent large migrations of anatomically modern humans into India—of agriculturalists from Iran between 7000 and 3000 BCE and Indo-European languages speaking pastoralists from the Central Asian Steppe (Aryans) between 2000 and 1000 BCE, among others. Tony Joseph used pizza as a metaphor to explain the break-up of subcontinental society. The book also discusses about similarities and differences between Indus Valley civilization and early Vedic civilization. The book mentions that ‘Aryan’ culture was most likely the result of interaction, adoption and adaptation among those who brought Indo-European languages to India and those who were already well-settled inhabitants of the region, and that Sanskrit and Vedas developed in the Indian subcontinent. Various tribes like the Andamanese and the Semang (Malay Peninsula), the Mani (Thailand) and the Aeta people (the Philippines) were the earliest inhabitants of Southeast Asia. According to Joseph, Proto-Dravidian is related to the Elamitic language of Iran. Caste system in India is a recent social system, reflected in sharply reduced inter-marriage (endogamy) and genetic mixing after 100 AD. This book also takes into account the path-breaking DNA research and findings from geneticist David Reich's research.

[Q]: Question: What year was the mine fire discovered that created a ghost town in Columbia County? Passage:PA 42 begins at an intersection with PA 61 in the near ghost town of Centralia in Columbia County, which has been largely abandoned because of a mine fire. From PA 61, the route heads north on two-lane undivided Locust Avenue. The road passes through abandoned areas of the town which have been overgrown with trees. The route turns east and crosses into Conyngham Township, becoming South Main Street and heading into forested areas. PA 42 becomes a four-lane road and heads to the northwest, passing through the residential community of Aristes, where it narrows back to two lanes. The road curves to the northeast and becomes Numidia Drive, heading into the Weiser State Forest and turning to the northwest as it crosses Big Mountain. The route turns west and northwest through more dense forests, passing to the east of Shamokin Reservoir. Continuing to the west-northwest, PA 42 enters Locust Township as it crosses Little Mountain, leaving the state forest and turning to the north. The road heads into open agricultural areas with some woods and residences. The route briefly turns northwest before heading north again and passing through the community of Numidia. PA 42 curves to the northwest as it heads through more rural areas, crossing the Roaring Creek and continuing into Catawissa Township. The road runs through a mix of farmland and woodland with some homes, gaining a second northbound lane. The route becomes a four-lane road in a wooded area before turning into a three-lane road with one northbound lane and two southbound lanes. PA 42 comes to an intersection with PA 487, at which point that route joins PA 42 for a concurrency, with the two routes heading north through more woodland as a two-lane road. The road crosses the Catawissa Creek into Catawissa and becomes Mill Street, heading northwest into residential areas. PA 42 splits from PA 487 by heading west-northwest on Main Street, heading through the commercial downtown of Catawissa. The road crosses Norfolk Southern's Sunbury Line before heading across the Susquehanna River, at which point the road becomes Rupert Drive and heads into Montour Township. Here, the route turns north and crosses the North Shore Railroad. PA 42 runs through wooded areas immediately to the west of the railroad tracks with the Susquehanna River a short distance to the east. The road turns north-northwest away from the railroad tracks and heads through the residential community of Rupert. The route passes through more woodland with some homes before reaching an interchange with US 11.
