A SECOND LOOK
A question to carry into the reading
When examining copper tripeptide-1, pause before carrying a conclusion from one context into another. Describe the context in the cited passage and the context you have in mind, using separate columns if that helps. Compare what is being evaluated, how it is presented, the period considered, and the result being sought. If any of those differ, ask what supports making the connection. Similar wording is a reason to inspect the relationship, not to skip that inspection. The finished note should identify the proposed transfer and its justification, while leaving unresolved differences visible rather than smoothing them into a broader claim.
Questions to keep beside the page
- Which features of the cited context match the context I have in mind?
- Where do the material, presentation, period, or intended result differ?
- What evidence would justify carrying the conclusion across those particular differences?
