When does bud know he will never beat todd amos?
a. when todd lies and his mother takes his side
b. when he sees that todd is bigger than he is
c. when todd's mother comes in and todd pretends he is sick
d. when todd attacks him with the pencil?

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.
