Distinguish source versions

Supplied materials

• Paper and pencil, or a browser text area. All named people/events/records are fictional learning inputs.
• Worked case: Excerpt A: Supplied key: Lee—Hinge Note, 2026, p. 2. The note should link Lee and Hinge Note to the reference entry. Excerpt B: Revision A says five bends; revision B corrects the text to six bends. The wording changed. Excerpt C: Research log: query paper hinge repeated bending; include dated test records with actual bend counts. Excerpt D: Card A records Jo’s test; Card B independently records Lea’s different test. Neither copied the other.
• Primary check: Excerpt A: Supplied key: Model Club—Test Card, 2026, section 1. The named organization authored this card. Excerpt B: A 2025 edition and a 2026 edition carry different publication dates, with no textual change supplied. Excerpt C: Research log: exclude Promotional Flyer because it has no dated trial result, the inclusion requirement. Excerpt D: Two websites reproduce the identical Trial Card A rather than conducting separate tests.

Learn the idea

Research records may have different dates, revised wording, another format or another translation. A reader should know which version supported a claim.

Inspect the stated version change and record the exact version used. Do not assume equal titles mean identical content.

Original worked input: Original excerpt B: Revision A says five bends; revision B corrects the text to six bends. The wording changed. The task is to distinguish source versions. The answer is “text was revised”. Evidence: Revision A says five bends; revision B corrects the text to six bends. The wording changed. Reasoning: text was revised is supported because a revised reported count changes source wording. PDF versus HTML alone does not prove different wording.

1. Read the supplied worked case and identify the part named in this lesson. An adult can model unfamiliar words.
2. Inspect the stated version change and record the exact version used. Do not assume equal titles mean identical content.
3. Check the worked solution: text was revised. Evidence: Revision A says five bends; revision B corrects the text to six bends. The wording changed. Reasoning: text was revised is supported because a revised reported count changes source wording. PDF versus HTML alone does not prove different wording.
4. Use the new primary and practice cases. Give a reason from the actual words before checking the feedback.

Take it further

Changed-input task: Original excerpt B: The same text is available in print and HTML, without a wording change. Give an evidence-based answer before looking at the model. Expected reasoning: Evidence: The same text is available in print and HTML, without a wording change. Reasoning: format changed without a text change is supported because the same wording is delivered in a different medium. PDF versus HTML alone does not prove different wording. Then write a brief alternative sentence, paragraph, source note or scene that demonstrates the same operation; label new fictional details and preserve source limits.
