What is the region known as the Sahel in Africa, and what are two countries that would be located (or partially located) in that region?
The Sahel is the region south of the Sahara desert proper; it is sometimes considers a southern sub-region of the desert, known for a dry (but not completely desertified) climate with land dominated by scrub and dry savanna. Two countries in this are Chad and Niger.
If we were playing on the piano, a D major triad (d f# a), and I asked you to turn it into a D major 7, what note would you add. If I asked for a D augmented triad rather than a major, what would change?
A D major 7 would involve adding c# to the d f# a triad, resulting in a major 7th between the root and the 7. To modify a d major triad to an augmented one, we would simply raise the a one half step, resulting in d f# a#.
What were two factors that gave rise to the dynamic known as "urban blight" or "urban decay" in American cities in the early to mid-twentieth century?
1. The increasing popularity and availability of the automobile gave people the opportunity to live farther from their places of business, helping to develop the concept of suburbs. 2. The decline of urban manufacturing in many cities, particularly the Upper Midwest and East Coast, resulted in the loss of jobs and abandonment of large tracts of urban land.
