1. B)

2. A)

Explanation:

1. The other name of aleatory music is a chance music because of the elements of the compositions that were left to chance while other elements were composed. Chance elements are considering a lot of possibilities and variability. This aleatory can also be found in films. Henry Cowell and John Cage were composing modern usage of aleatory music.

2. Renaissance motets like Ave Maria were sacred because medieval motets had that sacred chant which was Latin and it was requiring a lowest voice with secular or nonreligious texts in everyday language who was above them. Since the secularisation is considering separation of religion, those motets were sacred.
