How does your prior knowledge help you better understand civil disobedience give specific examples and discuss parts of the passage that your pre reading thought process helped you to understand

not concrete, existing in thought or as an idea but not having a physical or concrete existence

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.
