Explain how your thinking has evolved — changed or perhaps strengthened — on some issue we have considered in class.  In your essay, you should:
(i) summarize your perspective on the issue at the beginning of the semester;
(ii) defend or revised your position, with explicit reference to existing statistics/data, research papers, popular press presentations, and other supporting sources;
(iii) explain/acknowledge at least one limitation/weakness of your revised position, and one dimension that requires additional scrutiny.
