Here is another example of a simple error of omission that could have been caught if the student had read the essay aloud or given it to a friend to read. The word "of" should be between "calculation" and "the." That one small error makes the entire sentence awkward and confusing. If the instructor has to reread the sentence to try to understand its meaning, the flow of the essay is interrupted. If this happens often enough in the essay, it gives an overall bad impression on what otherwise might be a very good paper in terms of research.
Where in the world did I get that idea? Now I finally understand — and I'm so much the better man and citizen for the understanding — that the true, indeed the only , obligation any company's top management has is to its Board of Directors and major shareholders.

My appreciation for the wonderfulness of the FEH can only be deepened by this knowledge, even if I am now forced to gaze upon that wonderfulness from a cold and comfortless place outside the warmth and safety of its shelter.
