Do we need prescriptive rules of grammar? What would happen if we didn’t?

Sorry I’m just doing a Challenge

Explanation:

answer: make the students take turns and express their opinions in 30 second intervals

explanation: in montessori schools we do this in socratic discussions

i believe the answer is: b. mr. head had a long, tube-like face with a rounded open jaw and a short depressed nose.

this is because in the un-revised sentence it said that mr. heads face was long and tube-like, and he had a rounded open jaw. this is not a very grammatically correct because of how it seems to drag on with the and, replaced with, with, makes it sound more fluent in the description.
