A story describes events in this order: wake-up, bus ride, science fair, awards. What is the text's sequence structure?

• A. Cause and effect.
• B. Chronological (timeline) sequence.
• C. Compare and contrast.
• D. Problem and solution.

Answer: (B)

Sequence structure shows how events are arranged in time. In this story, the events happen in the order they occur during a day: wake-up, bus ride, science fair, awards. Because the text presents things in time order from first to last, it uses a chronological (timeline) sequence. Other structures would focus on why something happened (cause and effect), compare similarities or differences between things (compare and contrast), or present a problem and its solution; none of those are the pattern here—the emphasis is simply the order of events as they occur.
