Which term describes the main point or most important idea the author is conveying?

• A. Inference
• B. Central Idea
• C. Theme
• D. Author's Purpose

Answer: (B)

The main idea describes the overall point the author wants you to take away from the text. It’s the big message that ties together the details and evidence the author provides. In nonfiction, that’s often the thesis or claim the piece argues. In fiction, it’s the core message or insight about life that emerges from the plot and characters.

To spot it, look for what the paragraph or the piece as a whole is mostly about—what idea keeps coming up, what the author is trying to persuade you to believe, or what claim everything in the text supports. The central idea isn’t a single fact or detail, but the overarching point those details work to establish.

In contrast, an inference is a conclusion you draw from clues, a theme is a broader message about life the work suggests beyond the surface story, and the author’s purpose is why the author wrote the piece (to inform, persuade, entertain). For this question, the term that best fits the description of the main point the author is conveying is central idea. If a passage argues that regular reading improves knowledge and imagination, the central idea would be that reading daily has broad, positive effects, with the rest of the text supporting that claim.
