A. Paradox
In literature, a paradox is a statement that may seem silly, contradictory, and usually opposite to what is commonly believed or accepted, but that has a great potential to be true, and it may actually be.
This passage exemplifies a paradox because society normally believes that a worker on an oil rig behaves in a rough and uncouth manner, usually talking with curses or bad words and loud, and is not polite at all. However, this may be only a prejudice, as for someone's occupation does not necessarily determines how a person behaves. Someone who does hard manual labor not necessarily has to be rude, they may be, as well, elegant, and talk properly.
