Context and question: As it has on every aspect of Charleston culture, the Gullah community has had a tremendous influence on music in Charleston, especially when it comes to the early development of jazz music. In turn, the music of Charleston has had an influence on that of the rest of the country. The geechee dances that accompanied the music of the dock workers in Charleston followed a rhythm that inspired Eubie Blake's "Charleston Rag" and later James P. Johnson's "The Charleston", as well as the dance craze that defined a nation in the 1920s. "Ballin' the Jack", which was a popular dance in the years before "The Charleston", was written by native Charlestonian Chris Smith.
Who wrote the "Charleston"?

Context and question: Gorbachev also radically expanded the scope of Glasnost, stating that no subject was off-limits for open discussion in the media. Even so, the cautious Soviet intelligentsia took almost a year to begin pushing the boundaries to see if he meant what he said. For the first time, the Communist Party leader had appealed over the heads of Central Committee members for the people's support in exchange for expansion of liberties. The tactic proved successful: Within two years political reform could no longer be sidetracked by Party "conservatives." An unintended consequence was that having saved reform, Gorbachev's move ultimately killed the very system it was designed to save.
What group wanted to stop reforms?
Answer: "conservatives."
