Which text-structure pattern explains how one event leads to another, such as drought leading to crop failure?

• A. Compare/contrast; for example, two crops in different climates.
• B. Cause/effect; for example, a drought leads to crop failure.
• C. Chronological; For example, sequence of events.
• D. Problem/solution; for example, pest infestation and remedy.

Answer: (B)

Understanding how events are connected is about cause and effect. This pattern shows how one event brings about another, using clues like because, leads to, or as a result. In the drought example, the drought is the cause and crop failure is the effect, so the relationship is a clear cause/effect link. This is different from other patterns: compare/contrast would highlight similarities and differences between two things; chronological would simply list events in order without explaining why one leads to the next; problem/solution would present a trouble and then a remedy. The drought-to-crop-failure chain fits cause/effect best because it directly ties a cause to its consequence.
