Does the following sentence make use of parallel structure:
"Thus, Soyster’s diction most definitely exemplifies how he views himself in a dreary and pitiful manner and Mairs’s diction, contrariwise to Soyster’s, exemplifies how she views herself in a pleasant and benign manner."
If not, could you tell me how I can make it have parallel structure. I am very bad with English, and more mathematically inclined, so please break things down.
Thanks for the help.
