English 6th Grade SOL Practice Test

This question tests understanding of a text structure that shows how one thing leads to another. When a nonfiction article discusses how pollution causes health problems, it uses a cause-and-effect structure. It presents the cause (pollution) and then explains the effects (health problems), showing a direct link between them and often including evidence or examples to support that connection.

That explains why this option fits best. A chronological structure would focus on the order of events over time, not the relationship between pollution and health. A spatial structure would organize information by location. A problem/solution structure would present a problem and then propose or discuss solutions.
