Could you reasonably and logically argue for the OPPO SITE?
Does your thesis simply state that a poet is using a set of poetic elements? If it does, you should revise your thesis to answer the question “So What?” Why is that important? Or revise to argue that the poet is using the poetic element(s) in a particular way.
Is your thesis too obvious? Was it your first thought / reaction? If so, you might need to revise.
Have you developed your thesis after carefully analyzing the text(s)? Or did you choose it first and pick evidence to match?
Is your thesis making a reasonable argument AGAINST something?
What might be the typical or expected way of reading the text(s)? And how is your idea different?
Do you have sufficient evidence to explore and reason in order to connect to your idea?
