Explain how Elizabeth's choice to structure her speech this way helped make her argument more convincing.

the second sentence is a great revision in my opinion. that would be a great topic.

explanation:

c. barbarians with unexpected intelligence  

op: object of preposition

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.
