Answer please! take as long as you need, we are reading from the book "hidden figures" I can piece it together but you have to do the rest, (there is probably a PDF downloadable version.)

a) walter looks unhealthy

thousands of people

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.
