Which essential element explains the motives behind an event in a report?

The element that explains the motives behind an event in a report is "Why." This aspect delves into the reasons or motivations that led to an occurrence, providing context and depth to the understanding of the event. By addressing the "why," reports are better able to analyze the underlying influences, intentions, and circumstances that precipitated the event, ultimately allowing readers to grasp the significance and implications of what happened.

In contrast, focusing on "how" pertains to the methods or procedures involved in an event, while "what" gives a description of the event itself. "When" offers the timing or chronology of the occurrence. Together, "how," "what," and "when" provide a framework for understanding events, but it is the "why" that truly captures the essence of the motivations driving those events.
