This PowerPoint presentation discusses rules for proper pronoun reference and antecedents. It provides examples of pronoun errors and strategies for correcting ambiguous or unclear pronoun references. The rules address ensuring each pronoun refers to a single clear antecedent, avoiding pronouns that refer to possessive nouns, using pronouns like 'they' and 'it' precisely, and using 'who', 'which', and 'that' correctly depending on if the antecedent is a person, object, or unnamed item.
