The word "escape" (line 11) implies that Angelou feels O trapped by her obligations
O anxious about the morning
O guilty for leaving her family
O peaceful as she goes to sleep

yes you could be a life guard if that the question.

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.
