Explanation:

In music, the text refers to the words being sung. The meter is related to the rhythmic - time signature (such as duple or triple). Texture describes how the layers of sound interact, like monophonic (single - line) or changes in voice density. "Mass Proper" and "Mass Ordinary" are parts of the liturgical mass structure and not directly related to text, meter, or texture.

Answer:

text - no match from given terms in a direct sense
meter - Slow duple, triple
texture - all monophonic, frequent changes in the density of voices
