1. Always allow to complete a writing project. A. just enough time B. about one week C. more time than you think you'll need O D. at least one day​

I don't know what others says but in C.about one week I would have already completed the project work!!

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 would pick a. i think this is more of a personal question though.
