The type of metamorphism that takes place in response to large-scale mountain- building process is called as "Regional Metamorphism".

Explanation:

Regional  Metamorphism:

It is caused by massive geologic means such as mountain-building. These rocks, when exhibited to the surface, show the incredible pressure that induces the rocks to be bent and divided by the mountain building process. Regional metamorphism normally produces foliated rocks such as slates, gneiss, and schist.The differential strain normally occurs from tectonic forces that generate compressional tensions in the rocks, such as when two continental bodies collide. Hence, regionally metamorphosed rocks occur in the cores of thrust mountain regions or eroded mountain ranges.

The answer to this will be from your lab notes/procedure. it would be best to ask another student who participated in the lab as we do not know what was done, what enzyme or if the temperature is celsius or fahrenheit. if i were to guess though i'd say the rate stopped due to enzyme denturing at high temperature

Distillation.  distillation is the correct answer.
