Question 15 (1 point) Your friend Daniel notices wall supports that have a masonry block at ground level
and an arch that connects the block to the wall while studying gothic European
cathedrals. What structures is Daniel MOST LIKELY looking at?
flying buttresses
barrel vaults
lancet arches
Oribbed arches

Its flying buttresses just took the test.

Explanation:

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 !
