Question in the picture below

for many centuries, the catholic church has been a patron of the arts. the church has used various scientific methods to maintain its power.

not 100% sure though!

it is ram's horn i took the test got this anwser wrong due to the person above me !

it seems to me that yes they solo on the chord changes.  coltrane for sure solos on the chord changes. instead of changing scales, they use a different method over the chord changes. this melody is very  unique but may often times even be considered simple, which is quite common in this modal  type. for example, there are changes from the key of minor to major in this piece, which makes it  unique in its own way.
