Angela is writing a character analysis about the main character in white fang.

is this a question or a comment

you need need more details so we can understand what your asking us.

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.

this is a good question! i'll do some research and come back when i have the answer!
