When one event sets off a chain of related events.

When one event sets off a chain of related events.

• A. Domino Effect
• B. Dust Bowl
• C. Economy
• D. Electrification

Answer: (A)

A single action causing a chain of related outcomes is a domino effect. The idea is like a row of dominos: tipping the first one initiates a sequence where each event leads to the next. This captures why one event can set off a series of connected changes over time—the consequences unfold step by step because each result becomes the cause of the next. The term fits best because it centers on this cascading pattern. The Dust Bowl describes a specific historical disaster, not the general mechanism of cascading events. The economy or electrification are broader concepts or processes, not the metaphor for a sequence of connected events.
