These are the _ Mountains.
A) Rocky
B) Andes
C) Himalayan

C) Himalayan

Explanation:

I know that it is not Andes mountain because those mountains have "U"

shapes and not really pointy. I know that its not rocky mountains because it doesn't have snow and its very rough.

(a) i got it right on the test

i'm not sure i completely understand your question, but i will do my best.

i think the answer you are looking for is sequence. (see below)

a repeated melodic fragment would be best defined as repetition, while repeated chords (different or the same) could be a chord progression. however, you then mentioned the chord and melodic fragment beginning on higher or lower pitches, in that case, the answer could be best defined as a sequence. the definition of a sequence is as follows: "the restatement of a motif or longer melodic (or harmonic) passage at a higher or lower pitch in the same voice."

let me know if this !
