A) It gives one example to support the main idea about how the first day of college was a disaster.

answer: this is easy, i found "it"

i will repeat the question again, "find it."

here, i located it.

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.
