I'm trying to write a book review essay on the Scarlet Pimpernel as a placement test for a class I'm taking. The assignment says that i have to "Pick One Author theme that you saw played out over and over in the book, such as selfishness brings heartache or love is blind." and then the second part is "Pick one literary plot motif that is the strongest (such as Rags to Riches, Initiation, or Quest.)" What is the difference between the two?? I am so confused.
