Suppose you're writting a letter and recall a word you'd like to use but you don't know how its spelled if you wanted to look up the word in the dictionary you should use any of the following techinques except

the answer would be d. he tells the story through a teenage narrator.

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.
