Based on the Article ( Cool Cats( we can guess that the author is probably

A. In favor of protecting cheetahs
B. A trained veterinarian
C. Working at a zoo
D. Afraid of cheetad

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.

i believe it’s the first one, but it could be the second! not the third or fourth.

explanation:

you did not put the article. so i cannot answer the question.
