The comparison of the two texts is made through analysis, in which you examine aspects of the story including literary devices such as flashback, foreshadowing, metaphor, simile and personification.
The analysis asks how and why the two pieces of literature are similar and different, and what those similarities and differences express about the texts and about life in general.
Analysis requires your interpretation of the texts as well as your reflections on society, morals, history and human nature.
This focus is the statement of the paper and so, it must be selected thoroughly.
In these types of paper, a weak type of writing might just reject the entire paper.
