Tracking antecedents across sentences keeps pronouns anchored to their proper referents, preventing confusion. When a noun is introduced, it becomes the candidate for later pronouns, and as you move through a paragraph, several potential referents can exist. If you don’t actively map who each pronoun could refer to, a reader (or writer) might mistake one noun for another, especially when the text shifts subjects or introduces new characters. By keeping a mental or written map of who or what each pronoun points to and clarifying by reintroducing a noun when needed, you maintain a clear, continuous thread of meaning from sentence to sentence and paragraph to paragraph. This approach minimizes ambiguity, supports accurate comprehension, and makes writing more precise. The other strategies fall short because replacing all pronouns with nouns is impractical and awkward in natural writing and reading, guessing based on the closest noun in the current sentence often fails in longer or more complex passages, and skipping the pronoun removes essential connective tissue, leading to gaps in meaning.
