In the text coding system for active reading, which symbol marks something important?

• A. check mark
• B. x
• C. *
• D. RR

Answer: (C)

In active reading, using a symbol to flag important information helps you quickly find key ideas later. The star (*) is a clear, visually distinctive cue that signals something to pay extra attention to—such as main ideas, essential details, or important concepts you’ll want to revisit. A check mark tends to indicate completion or agreement rather than significance. An x usually marks something questionable or incorrect, not its importance. RR isn’t a standard marker for importance unless your specific system defines it that way, so it doesn’t convey priority as plainly as a star. So, the star is the best choice because it consistently signals that this part stands out as worth noting and reviewing.
