why is it important to use an organizational pattern in comparison and contrast essays?

A. to provide an outline of your essay

B. to provide details supporting the statements

C. to demonstrate your thesis

D. to clearly show the relationships between the items you are comparing

I would say the answer is D. to clearly show the relationships between the items you are comparing. The previous options are valid for all types of essays, not only the comparison and contrast ones. But the D option means that you really have to establish a thorough relationship between the compared items, and precisely know all the similarities and differences.
