Why the rewrite is better: The sentence turns administrative details into an analytical claim, names the unequal mechanism, and ties the paragraph directly to the essay's environmental justice argument.

More before and after examples

Novel analysis paragraph

Before

This paragraph comes after a section about unreliable narration. My point is that the repeated mirror scenes make the narrator confront versions of herself she has tried to leave out of the story.

After

The novel's mirror scenes turn unreliable narration into a visible conflict, forcing the narrator to confront the identities her own account repeatedly excludes.

Why the rewrite is better: The opener bridges from the preceding discussion, interprets the recurring image instead of merely noting it, and defines what the paragraph must demonstrate through close reading.

A topic sentence should establish the paragraph's job in the argument rather than simply introduce the next fact. This generator uses your paragraph point and overall thesis to create an opening with direction, scope, and a meaningful transition from the surrounding discussion. It can help diagnose paragraphs that contain useful evidence but lack a controlling idea. Once you have a candidate, make sure every sentence beneath it develops that exact claim; if the evidence pulls elsewhere, revise the topic sentence or divide the material into separate paragraphs.
