Warming up is important before exercising to (3 points) question 3 options: 1) decrease intensity 2) prevent injury 3) strengthen muscles 4) improve performance

I think it is 4) Improve performance.

I hope this helps, if I get it wrong I'm soo sorry.

what the fuck

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 !
