Concept 8

Choose coordination/subordination structures that reflect intended relationships.

Core Idea

Sentence structure should show the real relationship between ideas, not just place them side by side.

Understanding

Rule: Coordination gives equal weight to ideas. Subordination shows that one idea provides the reason, condition, contrast, or time frame for the other.

When ACT asks you to combine sentences, do not choose by rhythm alone. Choose the structure that tells the reader how the ideas connect.
