Final answer:
To improve sentence fluency and avoid redundancy, nouns can be replaced with pronouns that match in number and gender, or with gender-neutral pronouns such as 'they' to accommodate for unknown or non-binary gender identities.
Step-by-step explanation:
When revising sentences to incorporate pronouns effectively, it is important to ensure that they agree with their antecedents in terms of number and gender, and that they avoid gender bias or ambiguity. Replacing a repeated noun with an appropriate pronoun not only avoids redundancy but also improves sentence flow and coherence.
For example, in the sentence 'The child needed to use the bathroom, so the child asked a parent for help,' replacing the second mention of 'the child' with the pronoun 'he' or 'she' (depending on the child's gender) or 'they' (for a gender-neutral option) would be more concise and fluid.
