question:
Passage: Born in 1915, Margaret Esse Danner came of age in Chicago during the Great Migration. Sources place her birth in Pryorsburg, Kentucky, in 1915, although she adamantly claimed Chicago as her birthplace. In eighth grade, she won first prize in a school contest for "The Violin", a poem describing Stradivarius and Guarnerius violins. Danner's college education included courses at Loyola University, Northwestern University, YMCA College, and the newly founded Roosevelt College. Perhaps equally significant was her education in the African-American cultural community of Chicago's South Side, which in the 1930s and 1940s harbored grassroots cultural institutions and informal circles devoted to politics, education, art and literature and often tied to the Communist Popular Front. Although Danner stayed detached from Communism and would eventually oppose all radical politics, she participated in various South Side groups, including Inez Cunningham Stark's poetry workshop at the South Side Community Art Center, along with Gwendolyn Brooks and Margaret Goss Burroughs, her "sometime friends (and rivals)." In 1946, Danner founded Art Associates to gather and promote Chicago's black writers and poets. She counted as friends the poet and critic Edward Bland, as well as Hoyt Fuller, who would head the revived Negro Digest (later Black World) beginning in 1951.

question:
Passage: Four days before the end of the Second World War, undefended Bergen was occupied by the Red Army on 4 May 1945. After the German Democratic Republic (East Germany) was founded, the new government pressed ahead with further industrialization. In 1952, construction began on the industrial area on the town's western outskirts. From 1953 to 1958, the dairy was established, which furnished 300 tonnes of milk daily. In 1955/1956 came the establishment of the VEB Brot- und Backwaren (Bread and Baked Goods). In 1957/1958, the slaughterhouse and meat plant went into production. An efficient food industry was set up in Bergen, supplied from the island and parts of the mainland. Since Reunification and East Germany's accession into the Federal Republic, the town has undergone a number of marked changes. The population dwindled from its former level of almost 20,000 to 16,500. Many prefabricated concrete structures, common in the former Warsaw Pact countries, were modernized and adapted to new demands. In addition, a few schools were closed and new hotels built. Historical downtown was completely renovated and decorated, giving it a new appeal.

What countries were part of the pact that saw prefabricated concrete structures modernized?


question:
Passage: Dodds gained a reputation as a top young drummer in New Orleans. In 1918, Dodds left Sonny Celestin's outfit to play in Fate Marable's riverboat band. A young Louis Armstrong also joined the band, and the two of them were on the boats for three years (from 1918 to 1921). The band played on four different boats, and usually left New Orleans in May and travel to St. Louis, though they also sometimes traveled further north. They played jazz, popular, and classical music while on the boats. Dodds and Armstrong left Fate Marable's band in 1921 due to a disagreement about musical style, and Dodds soon joined King Oliver's Creole Jazz Band. At this time, the personnel in Oliver's band were Joe "King" Oliver on cornet, Baby Dodds' brother Johnny Dodds on clarinet, Davey Jones on alto saxophone, Honoré Dutrey on trombone, Lil Hardin on piano, Jimmy Palao on violin, and Eddie Garland on bass fiddle. They moved to California in 1921 to work with Oliver there, and they played together for about fifteen months. In 1922, the band, excepting Garland, Palao, and Jones, followed Oliver to Chicago, which would be his base of operations for several years. They began playing at the Lincoln Gardens, and Louis Armstrong also joined this outfit. Dodds describes playing with this band as "a beautiful experience". Dodds recorded with Louis Armstrong, Jelly Roll Morton, Art Hodes, and his brother Johnny Dodds. Dodds played in Louis Armstrong's Hot Five and Hot Seven groups. In May 1927 Armstrong recorded with the Hot Seven, which consisted of Johnny Dodds, Johnny St. Cyr, Lil Hardin Armstrong, John Thomas, Pete Briggs, and Baby Dodds. From September to December 1927 the Hot Five Armstrong assembled consisted of Johnny Dodds, Kid Ory, Johnny St. Cyr, Lonnie Johnson, and Baby Dodds.
