Topic Development (Purpose & Focus)
Development questions ask whether each sentence helps the writer do a job. On ACT English, the best choice keeps the paragraph focused and supported instead of merely adding more words.
Core Idea
Judge every detail by function. The right answer strengthens the main point with specific, relevant support, removes repetition, and keeps the paragraph consistent in focus, point of view, and level of detail.
Understanding
Rule: Development questions ask whether each sentence helps the writer do a job. The best choice keeps the paragraph focused and supported instead of merely adding more words.
- Ask first: is the paragraph explaining a process, supporting a claim, or showing why something matters?
- Judge details by function. ACT English rewards information that clarifies, proves, or sharpens the point. It does not reward facts that are merely true or loosely related.
- Strong development usually means one clear topic sentence, specific support, and revisions that keep the paragraph from drifting, repeating itself, or switching perspective without a reason.
