    Topic is the subject; central idea is what the author says about it. Topic = what it's about; central idea = the author's claim about it.

14. What does it mean when a passage has more than one central idea?

    It advances multiple main points that are each developed and linked. Complex texts can explore several interconnected main points.

    Synthesize repeated points and the author's overall claim. Look for patterns and the author's main argument across paragraphs.

24. What is an objective summary required to avoid?

    Personal opinions, judgments, and unsupported inferences. Objectivity requires sticking to facts the author presents.

    By repeated emphasis plus supporting examples, reasons, or evidence. Authors build their point through layers of proof and illustration.

32. Which detail is least relevant to the central idea "Bats control pests": "Eat insects nightly" or "Sleep upside down"?

    A specific piece of information that supports the central idea. Evidence or examples that directly develop the main point.

39. What is the primary purpose of a paragraph in relation to the central idea?

    To develop the central idea through a focused sub-point. Each paragraph advances the main argument with specific aspects.

40. What is a supporting detail in a passage?

    A specific fact, example, or reason that backs the central idea. These concrete elements provide evidence for the author's main argument.

41. Which option is a topic, not a central idea: "Renewable energy" or "Solar cuts costs"?

    Renewable energy. It names a subject without making any specific claim.

42. Identify the key detail: The author says tree shade lowers pavement temperatures.

    Tree shade lowers pavement temperatures. This fact directly supports the heat-reduction claim.

43. Which choice best distinguishes a topic from a central idea?

    Topic is broad; central idea is a specific claim about the topic. Topics name subjects; central ideas make assertions about them.

44. Which sentence is too broad to be the central idea of a specific passage? A) Technology affects society B) This text argues phones reduce attention

    A) Technology affects society. Too vague to capture a specific passage's unique argument.

48. What is the main difference between a central idea and a theme?

    Central idea is text-specific; theme is a broader universal message. Themes apply to many texts; central ideas are passage-specific.
