Which text feature is used to show step-by-step processes or chronological order?

• A. Table of contents
• B. Boldface
• C. Glossaries
• D. Timelines

Answer: (D)

Showing how events unfold over time is best done with a timeline. Timelines place events along a line in chronological order, often with dates. This layout lets you see what happened first, what followed, and how events relate to each other in time. It’s especially helpful for tracing a process that occurs step by step or for mapping the sequence of historical events, because the order is visually clear and time-stamped.

Other text features serve different purposes. A table of contents helps you navigate a text by listing chapters and page numbers, not by presenting time-based sequences. Boldface highlights important terms, and glossaries define those terms. They don’t arrange events in time, so they don’t convey chronological flow.
