Using the materials you have developed thus far in this section, write a 500-word expository essay. Check spelling by focusing on each word separately. Check for capitalization, proper use of parentheses, question marks, commas, semicolons, colons, and other punctuation marks. Check for proper use of grammar. Have you written in complete sentences using proper agreements between subjects, nouns, verbs, pronouns, and their antecedents? Check for correct facts, such as names, dates, titles, statistics, and exact wording of quotations.
