The term "additional information" refers to any piece of data or fact that provides more detail, clarification, or context about a particular topic. It is supplementary information that enhances our understanding and knowledge beyond what we already know. This can include statistics, quotes, anecdotes, expert opinions, or other relevant details that help us gain a deeper insight into the subject matter. In essence, "additional information" helps to round out our perception of something by providing more depth and perspective.
