Which of the following is best to include in the overview?

• A. Identify the most notable trend and summarize it succinctly
• B. List every data point
• C. Provide personal opinions
• D. Include technical jargon

Answer: (A)

The main idea of an overview is to present the big picture of the data—the overall pattern across the whole chart rather than the specifics. The best choice captures the most notable trend and summarizes it succinctly because it gives a clear, high-level takeaway that readers can grasp at a glance. This kind of statement shows the general direction, the main movement, and any striking contrasts without getting bogged down in numbers or minute details, and it nicely sets up the detailed descriptions that follow in the body of the response. If there are a couple of important patterns, you can mention them briefly in the overview, but keep it concise and avoid listing every data point. Personal opinions have no place in the overview, and using technical jargon tends to hinder readability. A strong overview might describe, in a single sentence or two, the overall rise or fall, any turning points, and how different parts relate, so the reader understands the data’s takeaway right away.
