Comparison and contrast writing is usually organized in one of two ways which are called block organization and point by point organization. Using Internet and library sources, explain the differences, and then identify which kind of organization is used in each essay assigned for this week. Note that a writer will sometimes use both. Also, point out the transitional words and expressions which the authors use to maintain coherence. You must use the assigned essays in your answer, but you may also use examples from essays previously read. Give appropriate quotations and document your sources.
