Question: In 1953, Korolev was given the go-ahead to develop the R-7 Semyorka rocket, which represented a major advance from the German design. Although some of its components (notably boosters) still resembled the German G-4, the new rocket incorporated staged design, a completely new control system, and a new fuel. It was successfully tested on August 21, 1957 and became the world's first fully operational ICBM the following month. It would later be used to launch the first satellite into space, and derivatives would launch all piloted Soviet spacecraft.
Is there an answer to this question: R-7 Semyorka rocket resembled closely to what other missile?

Answer: German G-4

Question: The Siddi are an ethnic group inhabiting India and Pakistan whose members are descended from Bantu peoples from Southeast Africa that were brought to the Indian subcontinent as slaves by Arab and Portuguese merchants. Although it is commonly believed locally that "Siddi" derives from a word meaning "black", the term is actually derived from "Sayyid", the title borne by the captains of the Arab vessels that first brought Siddi settlers to the area. In the Makran strip of the Sindh and Balochistan provinces in southwestern Pakistan, these Bantu descendants are known as the Makrani. There was a brief "Black Power" movement in Sindh in the 1960s and many Siddi are proud of and celebrate their African ancestry.
Is there an answer to this question: What does the word "Siddi" derive from?

Answer: "Sayyid"

Question: To be considered 'enriched', the uranium-235 fraction should be between 3% and 5%. This process produces huge quantities of uranium that is depleted of uranium-235 and with a correspondingly increased fraction of uranium-238, called depleted uranium or 'DU'. To be considered 'depleted', the uranium-235 isotope concentration should be no more than 0.3%. The price of uranium has risen since 2001, so enrichment tailings containing more than 0.35% uranium-235 are being considered for re-enrichment, driving the price of depleted uranium hexafluoride above $130 per kilogram in July 2007 from $5 in 2001.
Is there an answer to this question: How much did a kilogram of depleted uranium hexafluoride cost as of July 2007?

Answer: $130

Question: For English Dominican mystics, the mystical experience was not expressed just in one moment of the full knowledge of God, but in the journey of, or process of, faith. This then led to an understanding that was directed toward an experiential knowledge of divinity. It is important to understand, however, that for these mystics it was possible to pursue mystical life without the visions and voices that are usually associated with such a relationship with God. They experienced a mystical process that allowed them, in the end, to experience what they had already gained knowledge of through their faith only.
Is there an answer to this question: What was not important to English mystics?
