What term identifies the primary message an author conveys to readers?

• A. Plot
• B. Central idea
• C. Tone
• D. Setting

Answer: (B)

The main idea being tested is identifying the central idea—the primary message the author wants readers to take away. This captures the text’s overarching point that the author develops through details and examples. It’s different from other elements: plot is the sequence of events, tone is the author’s attitude toward the subject, and setting is where and when the action occurs. For example, a passage arguing that recycling benefits communities conveys a central idea about the tangible advantages of recycling. The other options describe aspects of how the story is told or where it happens, not the main message the author aims to convey.
