Roman felief sculptures show objects in their entirety with no overlapping in order to tell a story cleary, wheras egyptain and mesoptamian relief sculptures show objects more realistically using over lapping

True

Roman relief sculptures show objects in their entirety in order to tell a story clearly, whereas Egyptian and Mesopotamian relief sculptures show objects more realistically using overlapping.

a chromatic scale uses the twelve tones of the octave, while a regular scale only uses eight, or seven different notes (as the first note is played twice)

i think it's but if you get it wrong its not my fault : )
