Which enlightenment idea is reflected in both satan in john milton's paradise lost and daniel defoe's character of robinson crusoe?
a absolutism
b the noble savage
c deism
d liberalism

I will go with b. Noble Savage.  This is all about rebellion in put in a situation you don’t want to be in.  Both Crusoe and Satan were put in their own isolation.  Each reacts to his situation in his own way.  Satan retaliates by tempting Adam and Eve and Crusoe is striving to survive in the environment he finds himself in.

including the octave, the answer would 8 notes in a major scale with one note being played twice. ex) c major scale includes: c, d, e, f, g, a, b, c

notice that c is played twice

however, if you were to ask me how many different notes are in a major scale- the answer would be 7.
