A strike fund would have to be raised, an information bureau set up where strikers could register for relief, or for help with legal and personal problems. Publicity was another vital need — photos and eyewitness accounts of workers on the picket lines being harassed by gorillas and police. The picket lines themselves would have to be organized. Why was publicity a vital need for the strikers?

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.
