c. gene has to work nights to pay for college and is unable to attend all the cool parties.
d. a working college student misses out on fun activities, but his hard work him appreciate his degree.

Gene's hard work pays off in the end, and he graduates from the university at the top of his class. is the answer to original post btw

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.

you didn't show the passage, so unfortunately i cant you.
