To achieve clarity in an exposition, the writer should ____.
A. Limit his subject or the scope of discussion, for it’s impossible to explain many things clearly in a short essay.
B. Prepare enough material (details of examples) to help his explanation; the reader often finds abstract discussions hard to follow if they are not illustrated by concrete examples.
C. Present his facts and views in proper order, in the order of time or of logical sequence depending on the nature of the subjects.
D. Make his exposition, if possible, interesting or moving.
