When a writer revises an essay for coherence, he or she makes sure that
A. each paragraph connects smoothly and logically to the next.
B. all words are spelled properly.
C. errors in grammar are corrected.
D. all body paragraphs support the thesis statement.
Well, coherence means being logical, consistent, and forming a unified whole. Therefore, B, C, and D don't add anything to the coherence of an essay. Answer A, however, does. So, A is the answer. Hope this helps!
