Which term represents observations or symbols of differences in nature?

• A. Data
• B. Information
• C. Knowledge
• D. Wisdom

Answer: (A)

Observations or symbols of differences in nature are data. They are the raw, unprocessed facts you collect—numbers, measurements, counts, notes, or pixel values—taken from the natural world. Data don’t carry meaning on their own; they’re the basic material you start with. When you organize and interpret these data, you get information, such as a chart of averages or a trend line. From information, you gain knowledge when you understand patterns and relationships, and wisdom when you apply that knowledge to make good decisions. So data is the best answer because it refers to the raw observations and representations before any processing or interpretation.
