Answer
The structure of a timeline and a history article differ in that a timeline typically presents information in a linear fashion, while a history article may include a variety of elements such as a narrative, analysis, and argument. The structure of a timeline allows readers to quickly grasp the sequence of events, while the structure of a history article allows readers to gain a deeper understanding of the context and implications of the events. For example, a timeline may list the dates of major battles in a war, while a history article may provide an analysis of the causes and consequences of the war. The structure of each text thus contributes to the meaning of the text by providing readers with different levels of information.
