Question

in an informational text organized chronologically, where should the author introduce the central idea?

in the timeline
at the beginning
after the evidence
at the conclusion

Explanation:

Analyze the purpose of an introduction in informational texts

Regardless of the organizational structure (such as chronological, cause and effect, or comparison), an informational text must establish its central idea or thesis early to guide the reader's understanding.

Evaluate the placement options

• "in the timeline": A timeline is a supporting graphic feature, not the main text body where the central idea is introduced.
• "at the beginning": The introduction or beginning of the text is the standard and logical place to present the central idea so readers know the focus before reading the details.
• "after the evidence": Evidence is used to support a central idea that has already been introduced.
• "at the conclusion": The conclusion restates or summarizes the central idea rather than introducing it.

Answer:

• in the timeline
• at the beginning (Correct answer)
• after the evidence
• at the conclusion
