I was missing from school for some time and essay topics were given out and everyone received a different topic. Today my literature teacher talked to me and told me that the only topic left is >>Renaissance showed in Shakespeare's Romeo and Juliet<<.

I am not quite sure what to write about, because there is not much time left and I don't know what to build on.

I just want to find out about some of the topics in the book and then I will describe them myself. I hope that it is allowed.
Thanks.

When you say you aren't sure what to write about, are you trying to find another topic or do you mean you're not sure how to approach the topic you've been given?
