Final answer:
The main idea in an informational text is the most important or central thought that tells the reader what the text is about, usually presented through a topic sentence.
Step-by-step explanation:
The main idea in an informational text refers to the most important or central thought of a paragraph or larger section of text, which tells the reader what the text is about. This is usually captured in a topic sentence that suggests generally what the paragraph is talking about, often including a transition from previous paragraphs. An informational text aims to present facts and draws conclusions based on those facts, ensuring that the inferences rely on factual information. When examining an informational text, it is essential to capture statements that summarize ideas since these hold critical insights about the text’s purpose and position.
While evaluating the content, you might also encounter evidence that clarifies, proves, or explains the main idea. This supporting evidence can include details, examples, quotations, facts, analysis, or expert opinions that are integrated throughout the text to reinforce the central idea.
