What illustrates a sequential order?

The choice that illustrates a sequential order is the one that describes following a step-by-step process. Sequential order indicates that events or actions are arranged in a specific, logical progression where one step naturally follows another. In a step-by-step process, each step must be completed before moving on to the next, which reflects a clear sequence. This arrangement is essential for understanding processes, such as instructions in recipes or guidelines in assembly manuals, where the proper order is critical for successful outcomes.

The other options do not represent a structured sequence. A series of events occurring in a year might imply chronological aspects, but it does not guarantee a specific order essential for processes. A random collection of ideas lacks any arrangement or logical order, and a discussion about different times may touch on various events but does not necessarily present them in a clear sequential manner. Thus, the option highlighting a step-by-step process best exemplifies sequential order.
