Problem: Because of the difficulty of moving crude bitumen through pipelines, non-upgraded bitumen is usually diluted with natural-gas condensate in a form called dilbit or with synthetic crude oil, called synbit. However, to meet international competition, much non-upgraded bitumen is now sold as a blend of multiple grades of bitumen, conventional crude oil, synthetic crude oil, and condensate in a standardized benchmark product such as Western Canadian Select. This sour, heavy crude oil blend is designed to have uniform refining characteristics to compete with internationally marketed heavy oils such as Mexican Mayan or Arabian Dubai Crude.
What is the usually sold standard blend of bitumen and oils named?

Answer: Western Canadian Select

Problem: Tennessee politics, like that of most U.S. states, are dominated by the Republican and the Democratic parties. Historian Dewey W. Grantham traces divisions in the state to the period of the American Civil War: for decades afterward, the eastern third of the state was Republican and the western two thirds voted Democrat. This division was related to the state's pattern of farming, plantations and slaveholding. The eastern section was made up of yeoman farmers, but Middle and West Tennessee cultivated crops, such as tobacco and cotton, that were dependent on the use of slave labor. These areas became defined as Democratic after the war.
What type of farmers inhabited eastern Tennessee in the late 19th century?

Answer:
yeoman
