Organization, Unity, and Cohesion

Organization questions on ACT English are really logic questions. The right answer makes the paragraph easier to follow from one sentence to the next.

Core Idea

Track what each sentence is doing and how it connects to its neighbors. A strong answer places ideas where their references are clear, uses a transition that names the real relationship, and opens or closes the paragraph without drifting away from its purpose.

Understanding

Rule: Organization questions test whether the paragraph's logic is easy to follow.

Start local. Ask what a sentence refers to, what point it develops, and which nearby sentence sets it up.
Words like "this," "that," time markers, and repeated nouns usually reveal the best placement.
Pattern check: setup → example → result; claim → evidence → takeaway; problem → response → effect.

Question

Worked Example

Concept Guides

Choose a logical sequence for sentences and paragraphs (chronological, cause–effect, compare–contrast, problem–solution).

Place sentences where they best support the surrounding ideas.

Select transitions that accurately signal relationships (addition, contrast, cause, example, conclusion).

Ensure pronouns and references are clear and connect smoothly to prior nouns/ideas.

Maintain paragraph unity by aligning each sentence with the paragraph’s controlling idea.

Improve coherence by combining, splitting, or rephrasing sentences to reduce abrupt shifts.

Build effective introductions that set context and focus.

Build effective conclusions that reinforce purpose without introducing new, unrelated ideas.
