Reread this passage from Narrative of the Life of Frederick Douglass, An American Slave. He said, "If you give a slave an inch, he will take a mile. A slave should know nothing but to obey his master--to do as he is told to do. Learning would spoil the best slave in the world.
What is the denotative meaning of spoil, as it is used in this passage?
endanger
ruin
save
persuade

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 !

the answer is letter b. false. fugue is a complex musical composition that does not occur or come together at the same time. in fact, it is composed of a number of voices or parts where the theme is introduced in one part and successively imitated in other parts.
